Why does Bitcoin have Ridiculously High Fees and Slow

Crypto-Powered - The Most Promising Use-Cases of Decentralized Finance (DeFi)

Crypto-Powered - The Most Promising Use-Cases of Decentralized Finance (DeFi)
A whirlwind tour of Defi, paying close attention to protocols that we’re leveraging at Genesis Block.
https://reddit.com/link/hrrt21/video/cvjh5rrh12b51/player
This is the third post of Crypto-Powered — a new series that examines what it means for Genesis Block to be a digital bank that’s powered by crypto, blockchain, and decentralized protocols.
Last week we explored how building on legacy finance is a fool’s errand. The future of money belongs to those who build with crypto and blockchain at their core. We also started down the crypto rabbit hole, introducing Bitcoin, Ethereum, and DeFi (decentralized finance). That post is required reading if you hope to glean any value from the rest of this series.
97% of all activity on Ethereum in the last quarter has been DeFi-related. The total value sitting inside DeFi protocols is roughly $2B — double what it was a month ago. The explosive growth cannot be ignored. All signs suggest that Ethereum & DeFi are a Match Made in Heaven, and both on their way to finding strong product/market fit.
So in this post, we’re doing a whirlwind tour of DeFi. We look at specific examples and use-cases already in the wild and seeing strong growth. And we pay close attention to protocols that Genesis Block is integrating with. Alright, let’s dive in.

Stablecoins

Stablecoins are exactly what they sound like: cryptocurrencies that are stable. They are not meant to be volatile (like Bitcoin). These assets attempt to peg their price to some external reference (eg. USD or Gold). A non-volatile crypto asset can be incredibly useful for things like merchant payments, cross-border transfers, or storing wealth — becoming your own bank but without the stress of constant price volatility.
There are major governments and central banks that are experimenting with or soon launching their own stablecoins like China with their digital yuan and the US Federal Reserve with their digital dollar. There are also major corporations working in this area like JP Morgan with their JPM Coin, and of course Facebook with their Libra Project.
Stablecoin activity has grown 800% in the last year, with $290B of transaction volume (funds moving on-chain).
The most popular USD-pegged stablecoins include:
  1. Tether ($10B): It’s especially popular in Asia. It’s backed by USD in a bank account. But given their lack of transparency and past controversies, they generally aren’t trusted as much in the West.
  2. USDC ($1B): This is the most reputable USD-backed stablecoin, at least in the West. It was created by Coinbase & Circle, both well-regarded crypto companies. They’ve been very open and transparent with their audits and bank records.
  3. DAI ($189M): This is backed by other crypto assets — not USD in a bank account. This was arguably the first true DeFi protocol. The big benefit is that it’s more decentralized — it’s not controlled by any single organization. The downside is that the assets backing it can be volatile crypto assets (though it has mechanisms in place to mitigate that risk).
Other notable USD-backed stablecoins include PAX, TrueUSD, Binance USD, and Gemini Dollar.
tablecoins are playing an increasingly important role in the world of DeFi. In a way, they serve as common pipes & bridges between the various protocols.

Lending & Borrowing

Three of the top five DeFi protocols relate to lending & borrowing. These popular lending protocols look very similar to traditional money markets. Users who want to earn interest/yield can deposit (lend) their funds into a pool of liquidity. Because it behaves similarly to traditional money markets, their funds are not locked, they can withdraw at any time. It’s highly liquid.
Borrowers can tap into this pool of liquidity and take out loans. Interest rates depend on the utilization rate of the pool — how much of the deposits in the pool have already been borrowed. Supply & demand. Thus, interest rates are variable and borrowers can pay their loans back at any time.
So, who decides how much a borrower can take? What’s the process like? Are there credit checks? How is credit-worthiness determined?
These protocols are decentralized, borderless, permissionless. The people participating in these markets are from all over the world. There is no simple way to verify identity or check credit history. So none of that happens.
Credit-worthiness is determined simply by how much crypto collateral the borrower puts into the protocol. For example, if a user wants to borrow $5k of USDC, then they’ll need to deposit $10k of BTC or ETH. The exact amount of collateral depends on the rules of the protocol — usually the more liquid the collateral asset, the more borrowing power the user can receive.
The most prominent lending protocols include Compound, Aave, Maker, and Atomic Loans. Recently, Compound has seen meteoric growth with the introduction of their COMP token — a token used to incentivize and reward participants of the protocol. There’s almost $1B in outstanding debt in the Compound protocol. Mainframe is also working on an exciting protocol in this area and the latest iteration of their white paper should be coming out soon.
There is very little economic risk to these protocols because all loans are overcollateralized.
I repeat, all loans are overcollateralized. If the value of the collateral depreciates significantly due to price volatility, there are sophisticated liquidation systems to ensure the loan always gets paid back.

Investments

Buying, selling, and trading crypto assets is certainly one form of investing (though not for the faint of heart). But there are now DeFi protocols to facilitate making and managing traditional-style investments.
Through DeFi, you can invest in Gold. You can invest in stocks like Amazon and Apple. You can short Tesla. You can access the S&P 500. This is done through crypto-based synthetics — which gives users exposure to assets without needing to hold or own the underlying asset. This is all possible with protocols like UMA, Synthetix, or Market protocol.
Maybe your style of investing is more passive. With PoolTogether , you can participate in a no-loss lottery.
Maybe you’re an advanced trader and want to trade options or futures. You can do that with DeFi protocols like Convexity, Futureswap, and dYdX. Maybe you live on the wild side and trade on margin or leverage, you can do that with protocols like Fulcrum, Nuo, and DDEX. Or maybe you’re a degenerate gambler and want to bet against Trump in the upcoming election, you can do that on Augur.
And there are plenty of DeFi protocols to help with crypto investing. You could use Set Protocol if you need automated trading strategies. You could use Melonport if you’re an asset manager. You could use Balancer to automatically rebalance your portfolio.
With as little as $1, people all over the world can have access to the same investment opportunities and tools that used to be reserved for only the wealthy, or those lucky enough to be born in the right country.
You can start to imagine how services like Etrade, TD Ameritrade, Schwab, and even Robinhood could be massively disrupted by a crypto-native company that builds with these types of protocols at their foundation.

Insurance

As mentioned in our previous post, there are near-infinite applications one can build on Ethereum. As a result, sometimes the code doesn’t work as expected. Bugs get through, it breaks. We’re still early in our industry. The tools, frameworks, and best practices are all still being established. Things can go wrong.
Sometimes the application just gets in a weird or bad state where funds can’t be recovered — like with what happened with Parity where $280M got frozen (yes, I lost some money in that). Sometimes, there are hackers who discover a vulnerability in the code and maliciously steal funds — like how dForce lost $25M a few months ago, or how The DAO lost $50M a few years ago. And sometimes the system works as designed, but the economic model behind it is flawed, so a clever user takes advantage of the system— like what recently happened with Balancer where they lost $500k.
There are a lot of risks when interacting with smart contracts and decentralized applications — especially for ones that haven’t stood the test of time. This is why insurance is such an important development in DeFi.
Insurance will be an essential component in helping this technology reach the masses.
Two protocols that are leading the way on DeFi insurance are Nexus Mutual and Opyn. Though they are both still just getting started, many people are already using them. And we’re excited to start working with them at Genesis Block.
https://preview.redd.it/wf1xvq3z12b51.png?width=700&format=png&auto=webp&s=70db1e9587f57d0c470a4f9f4523c216929e1876

Exchanges & Liquidity

Decentralized Exchanges (DEX) were one of the first and most developed categories in DeFi. A DEX allows a user to easily exchange one crypto asset for another crypto asset — but without needing to sign up for an account, verify identity, etc. It’s all via decentralized protocols.
Within the first 5 months of 2020, the top 7 DEX already achieved the 2019 trading volume. That was $2.5B. DeFi is fueling a lot of this growth.
https://preview.redd.it/1dwvq4e022b51.png?width=700&format=png&auto=webp&s=97a3d756f60239cd147031eb95fc2a981db55943
There are many different flavors of DEX. Some of the early ones included 0x, IDEX, and EtherDelta — all of which had a traditional order book model where buyers are matched with sellers.
Another flavor is the pooled liquidity approach where the price is determined algorithmically based on how much liquidity there is and how much the user wants to buy. This is known as an AMM (Automated Market Maker) — Uniswap and Bancor were early leaders here. Though lately, Balancer has seen incredible growth due mostly to their strong incentives for participation — similar to Compound.
There are some DEXs that are more specialized — for example, Curve and mStable focus mostly only stablecoins. Because of the proliferation of these decentralized exchanges, there are now aggregators that combine and connect the liquidity of many sources. Those include Kyber, Totle, 1Inch, and Dex.ag.
These decentralized exchanges are becoming more and more connected to DeFi because they provide an opportunity for yield and earning interest.
Users can earn passive income by supplying liquidity to these markets. It usually comes in the form of sharing transaction fee revenue (Uniswap) or token rewards (Balancer).
https://preview.redd.it/wrug6lg222b51.png?width=700&format=png&auto=webp&s=9c47a3f2e01426ca87d84b92c1e914db39ff773f

Payments

As it relates to making payments, much of the world is still stuck on plastic cards. We’re grateful to partner with Visa and launch the Genesis Block debit card… but we still don’t believe that's the future of payments. We see that as an important bridge between the past (legacy finance) and the future (crypto).
Our first post in this series shared more on why legacy finance is broken. We talked about the countless unnecessary middle-men on every card swipe (merchant, acquiring bank, processor, card network, issuing bank). We talked about the slow settlement times.
The future of payments will be much better. Yes, it’ll be from a mobile phone and the user experience will be similar to ApplePay (NFC) or WePay (QR Code).
But more importantly, the underlying assets being moved/exchanged will all be crypto — digital, permissionless, and open source.
Someone making a payment at the grocery store check-out line will be able to open up Genesis Block, use contactless tech or scan a QR code, and instantly pay for their goods. All using crypto. Likely a stablecoin. Settlement will be instant. All the middlemen getting their pound of flesh will be disintermediated. The merchant can make more and the user can spend less. Blockchain FTW!
Now let’s talk about a few projects working in this area. The xDai Burner Wallet experience was incredible at the ETHDenver event a few years ago, but that speed came at the expense of full decentralization (can it be censored or shut down?). Of course, Facebook’s Libra wants to become the new standard for global payments, but many are afraid to give Facebook that much control (newsflash: it isn’t very decentralized).
Bitcoin is decentralized… but it’s slow and volatile. There are strong projects like Lightning Network (Zap example) that are still trying to make it happen. Projects like Connext and OmiseGo are trying to help bring payments to Ethereum. The Flexa project is leveraging the gift card rails, which is a nice hack to leverage existing pipes. And if ETH 2.0 is as fast as they say it will be, then the future of payments could just be a stablecoin like DAI (a token on Ethereum).
In a way, being able to spend crypto on daily expenses is the holy grail of use-cases. It’s still early. It hasn’t yet been solved. But once we achieve this, then we can ultimately and finally say goodbye to the legacy banking & finance world. Employees can be paid in crypto. Employees can spend in crypto. It changes everything.
Legacy finance is hanging on by a thread, and it’s this use-case that they are still clinging to. Once solved, DeFi domination will be complete.

Impact on Genesis Block

At Genesis Block, we’re excited to leverage these protocols and take this incredible technology to the world. Many of these protocols are already deeply integrated with our product. In fact, many are essential. The masses won’t know (or care about) what Tether, USDC, or DAI is. They think in dollars, euros, pounds and pesos. So while the user sees their local currency in the app, the underlying technology is all leveraging stablecoins. It’s all on “crypto rails.”
https://preview.redd.it/jajzttr622b51.png?width=700&format=png&auto=webp&s=fcf55cea1216a1d2fcc3bf327858b009965f9bf8
When users deposit assets into their Genesis Block account, they expect to earn interest. They expect that money to grow. We leverage many of these low-risk lending/exchange DeFi protocols. We lend into decentralized money markets like Compound — where all loans are overcollateralized. Or we supply liquidity to AMM exchanges like Balancer. This allows us to earn interest and generate yield for our depositors. We’re the experts so our users don’t need to be.
We haven’t yet integrated with any of the insurance or investment protocols — but we certainly plan on it. Our infrastructure is built with blockchain technology at the heart and our system is extensible — we’re ready to add assets and protocols when we feel they are ready, safe, secure, and stable. Many of these protocols are still in the experimental phase. It’s still early.
At Genesis Block we’re excited to continue to be at the frontlines of this incredible, innovative, technological revolution called DeFi.
---
None of these powerful DeFi protocols will be replacing Robinhood, SoFi, or Venmo anytime soon. They never will. They aren’t meant to! We’ve discussed this before, these are low-level protocols that need killer applications, like Genesis Block.
So now that we’ve gone a little deeper down the rabbit hole and we’ve done this whirlwind tour of DeFi, the natural next question is: why?
Why does any of it matter?
Most of these financial services that DeFi offers already exist in the real world. So why does it need to be on a blockchain? Why does it need to be decentralized? What new value is unlocked? Next post, we answer these important questions.

Network effect doesn't explain Bitcoin dominance : technical arguments for Bitcoin Maximalism

I often saw some Bitcoiners counter the altcoin shillers with the following argument: "Bitcoin is the first so it has the network effect, so your altcoin will always worth less"
This is not totally wrong but I think this argument is bad. Using it implies implicitly that you admit that Bitcoin is technically less capable than altcoins with their higher transaction rate, fast blocks, instant confirmation, without fees and smart contract support....

And this is WRONG ! Bitcoin price is higher, because Bitcoin is already TECHNICALLY BETTER than any other altcoin and not because of network effect. In 2017, Bitcoin dominance was lower, some altcoin reaches almost the same level than Bitcoin. So network effect is not what prevents an altcoin to take the lead but it is the fact that almost all altcoin that pretend to be better than Bitcoin are technically flawed.
Why ? They use bigger blocks, DAGs (Directed Acyclic Graphs, like used in IOTA or Nano) or wtf they created to disturbe you and make you believe they are better than the good old Bitcoin blockchain. But they have at least one of these two weak points: validation time oand bandwidth.

If they use biggefaster blocks, validation time of block is higher and so block propagation is slower. Less nodes can operate as they may not be able to validate blocks fast enough to keep up with the tip of the chain. You end up like Ethereum that has less and less full verification nodes leading to centralization of the network.
If they use DAGs, they achieve consensus through a "proof-of-stake" vote and always at the cost of bandwidth (quadratic cost in number of node, linear in transaction rate). DAGs are often presented as "each node has its own ledger" but the reality is that the only global ledger you should trust is the complete DAG of the ledgers of each node. Only servers with a shitload of download bandwidth can maintain it as debunked here and here. To not look (in fact be) centralized, some DAG altcoins doesn't, opening the door to history rewrite by buying account that owned a big stake before and still use a lot of bandwidth to reach consensus. Bitcoin just add 80 bytes of proof-of-work data on a block of 1-2MB to achieve it and protect from history rewrite, almost zero cost for the network (that's why we pay fees to miners who carry the cost).
You only have those problems when it reaches a critical level of usage and only then we can see how much those limits where ignored. Until now, very few altcoins reached the limit (maybe Ethereum, and IOTA shows us it is centralized already by stopping the network)
Bitcoin has the highest price because Bitcoin is technically the only possible decentralized king (and a centralized cryptocurrency worths nothing). Yes maybe 1MB limit was too conservativ, yes fees are higher, yes 10 minutes is slow. But if everyone wants their coffee payment to be settled onchain, 1MB or 8MB or 32MB each 10 minutes, minutes or secondes will never be enough while it is a big difference for the network health. You only need the blockchain for settlement, for payment you have Lightning Network that can already destroy PayPal's transaction rate.
So next time you feel convinced by an altcoin that pretend to be better than Bitcoin while being decentralized by design, evaluate the requirement to be a fully validating node and what the overhead of bandwidth needed to achieve consensus. The chances are high that they didn't take care of one of these two issues and end up centralized or broken. You don't need the network effect argument.

Blockchain in Healthcare: Bridging Trust in response to COVID-19

Blockchain in Healthcare: Bridging Trust in response to COVID-19
Link to our article: https://block.co/blockchain-in-healthcare/
There’s never been a better time to provide proof-of-health solutions in the healthcare system globally. While it’s difficult to comprehend the significance of the role that technology may offer in such difficult times, essentially it can be nailed down to its basic concept of simplifying work and coordinating activities, which could have helped avoid the worst crisis people have experienced in their lifetime. If the healthcare system would adopt technological innovations in the early stages, it could have benefited and saved many lives.
Although the healthcare system has traditionally been slow in embracing the latest digital solutions, just like many other industries, we’ve observed in a previous article how the Covid-19 crisis has accelerated the adoption of digital technologies on a global scale in several industries, including healthcare.
The latest webcast brought to the audience by Block.co hosted some high profile experts from the industry. They illustrated how blockchain especially, together with other technologies such as IoT, and AI could in the future help elevate prompt responses, and provide more secure and efficient storage of data, something that has been missed in the recent pandemic.
Ahmed Abdulla from Digipharm, Dr. Alice Loveys from EY, and Dimitrios Neocleous from VeChain were hosted by Georgina Kyriakoudes, one of the first in the world to hold an MSc in Digital Currency, founder of Dcentric.Health and creator of the permissioned blockchain ecosystem app called Aria, which aims to transform the patient healthcare experience by giving individuals full control of their medical records.
Blockchain’s benefits in healthcare are primarily identified by efficiency, specifically on the transfer of data, facilitation of goods transport via the supply chain, prevention of counterfeit medicines sale, secure storage, and exchange of data around ID management. The impressive projects all the webcast guests have developed in the industry enable just these features, from the digitization of patient records to storage and exchange of medical data as well as easier processing of funds.
https://preview.redd.it/7k85objjz1851.png?width=768&format=png&auto=webp&s=237293e731024ae8f50861682c434b04d7742e05
Ahmed Abdulla founded Digipharm with the idea of issuing tokens to allow patients to be in control of their medical records at all times. Moreover, tokens are issued to be paid for anonymously sharing personal medical data to help research; pay for healthcare based on how it has improved quality of life.
We have experienced a disparity in Covid-19 tests costs around the world. For instance, getting tested in Cyprus costs around €60 while in the US it may add up to a few thousand dollars. This is due to the way countries arrange payment setups from payers to providers. Blockchain empowers people to take ownership of their records and funds while providing transparency of processes. This is where blockchain can be robust, by increasing transparency and allowing the patient to secure money transfer and hold their own records”, stated Ahmed.
His work as blockchain advisor at the UN Economic Commission for Europe is helping set up standards for the blockchain ecosystem, namely how the system should be used safely, and in a way that benefits all stakeholders.
“I lead the blockchain and healthcare team at the UN center for trade facilitation and e-business where we developed a blockchain and trade facilitation white paper; the second phase will soon provide an advanced technology advisory board to advise private or public stakeholders on what’s the best technology to use. It might not always be blockchain, hence we first understand and then advise if the tech is right for them or not. Blockchain is clunky, expensive, and not always proper for the organization we work with”, continued the blockchain expert.
Most people may prefer public and permissionless blockchain because it has major advantages over a private and permissioned one. Transparency stands out for the way the ledger is shared and for due diligence becoming unnecessary as a result. This means costs are also cheaper, in the range of 100% lower. On the other hand, a public decentralized blockchain has a major disadvantage since no legal framework is laid out. This means uncertainty as there is still a grey area in the legal field that might create confusion.
Dimitrios Neocleous is Ecosystem Manager at VeChain Tech and directly supported digital and technological solutions provider I-DANTE with the creation of the E-NewHealthLife and the E-HCert for the Mediterranean Hospital of Cyprus. Both apps give patients control over their health records, improve medical data sharing, and increase hospital operational efficiencies by simplifying the process of visiting a hospital.
E-NewHealthLife is a complex ecosystem solution that starts from a patient’s visit to an emergency room. A card with the reason for a patient’s visit is issued; it gets time-stamped; the patient is sent to the waiting room; once the patient’s turn comes and the medical check is completed, the card is scanned and the visit is closed. Patients can digitally access all diagnoses that took place anytime at the hospital.
“The platform produces a digital health passport, which is an encrypted non-fungible card that patients can use to identify themselves automatically when registering at the hospital’s emergency room. The passport is stored within a mobile app called E-HCert, which keeps track of each patient’s medical data and can be shared as needed”, announced Dimitrios.
E-HCert App is a Covid-19 lab test electronic wallet and pushes up the results of a patient who’s been tested for COVID. It has been proven to be very successful so far; currently, 2000 people who transited through the Larnaca airport in Cyprus have downloaded the app. With time-stamped records, it’s able to provide data such as the day and time when the sample was collected, it offers immutability, security, and integrity of data.
https://preview.redd.it/kqq7jfgpz1851.png?width=940&format=png&auto=webp&s=2c9a121e0a4839125418db7ff61ae3957c3fff41
“Covid-19 showed a deficiency in healthcare. The spread of the virus could have been prevented if we had digitization of processes and transparency of data through blockchain, and transfer of data through an authorized share of records. An open permissionless decentralized blockchain helps bring ownership of medical records back to the patient, and that is not possible in a centralized system”, continued the VeChain representative.
Dr. Alice Loveys is EY ‘s healthcare blockchain leader in the US and has been at the forefront of emerging healthcare technologies for her entire career including being a pioneer in electronic health record adoption, health information exchange, and privacy and security.
She believes that “blockchain technology is like a plumbing system that brings clean and transparent trusted data that can be used. It’s not proper for a track and trace system as it invades privacy unless there is the consent from patients, in that case, blockchain transparent share of data would be extremely useful for medical research and testing”.
One problem we experienced during the crisis is the confusion that arose with divulged information and the frustration that comes with it. People do not understand anymore which information can be trusted; at first, it looked like COVID-19 symptoms were not dangerous, then it came out that they actually were. Masks were not useful at the beginning, then they suddenly became necessary.
“Blockchain could have prevented lockdown and economic crisis through data management in that a much faster response would have been provided to tackle misinformation because blockchain can help manage data from different sources”, continues Dr. Loveys. “Moreover, it’s a great way to protect the database. Instead of moving any private sensitive medical data through the more traditional digital systems, blockchain simply allows us to send an algorithm, encrypted data that safeguards the information. It’s not a great use as a database as it does not scale, therefore we would not be able to store information for billions of people in it. But for the data that is in the blockchain, using algorithms, makes it very convenient and secure”.
Another topic discussed during the webcast was the GDPR compliance for blockchain. GDPR (General Data Protection Regulation) was created before blockchain therefore it doesn’t account for decentralized technologies. Generally speaking, it all comes down to how the technology is used and what kind of data is incorporated in it. Timestamping data without invading anyone’s privacy, or timestamp of consented data, should determine no issue at all. This is what privacy by design stands for, taking human values into account in a well-defined manner throughout the whole process.
Block.co, powered by the University of Nicosia, is establishing itself as a global leader in the issuance of digital immutable and secure certificates timestamped on the Bitcoin blockchain. In the field of healthcare, it could include medical records, prescription issuance, insurance disputes, supply chain documentation, and any type of verifiable certificate that requires authenticity at its core.

Liquid CAD: Canadian dollar payments on the Liquid Sidechain

Hello fellow Canadian bitcoiners or bitcoinca! You will find below all the information related to the launch of Liquid CAD and Bull Bitcoin's Liquid Bitcoin integration. I'll be checking comments here to answer your questions! I'm also posting some comments on my announcement tweet here: https://twitter.com/francispouliot\_/status/1245758698120605697?s=20

Making the Canadian Dollar Bleed Into Bitcoin

Building the infrastructure for the Bitcoin Standard in Canada before the collapse of fiat currencies is the critical mission objective that drives innovation at Bull Bitcoin.
We are very excited to announce an important milestone in fulfilling this duty: the public release of Liquid CAD, our newest product designed to accelerate and facilitate the adoption of Bitcoin.
Liquid CAD is a non-custodial prepaid payment system denominated in Canadian dollars. Units of Liquid CAD (L-CAD) consist of vouchers issued on the Liquid Network as confidential bearer assets that can be transacted peer-to-peer using a Liquid wallet.
Users acquire Liquid CAD by withdrawing their account balance out of Bull Bitcoin, by purchasing Liquid CAD with Bitcoin on Bull Bitcoin, by using the Liquid CAD withdrawal method on other Bitcoin liquidity providers such as Aquanow or by accepting L-CAD as method of payment.
L-CAD assets can only be redeemed for Bitcoin. They cannot be redeemed for a fiat currency payment.
Liquid CAD is a unique project rethinking the concept of fiat-pegged assets, avoiding the banking business model of “fiatcoin” (aka stablecoins) in favor of a prepaid payments model entirely centred around Bitcoin on-ramp and off-ramp. Liquid CAD is not a currency, nor is it a security: it is a prepaid card.
Importantly, the business model of Liquid CAD is not to collect interest on funds in our custody, unlike fiatcoins, but rather to drive the sales of Bitcoin from which we derive our revenue and we benefit from Liquid CAD assets being cashed out and thus removed from our balance sheet. Bull Bitcoin does not get any revenue from interest.
Every time an L-CAD token is purchased by a user, the amount of dollars deposited on Bull Bitcoin is guaranteed to one day be used by someone to purchase Bitcoin. It’s a one-way street: once a unit of fiat is tokenized as L-CAD, it’s never going back to its off-chain fiat form and will ultimately result in a buy order on a Bitcoin trading platform.
The Liquid CAD logo is a drop of blood because our objective is to accelerate “fiat bleed”, a phenomenon best described by Pierre Rochard in his magnificent essay Speculative Attack:
“Bitcoin will not be eagerly adopted by the mainstream, it will be forced upon them. Forced, as in “compelled by economic reality”. People will be forced to pay with bitcoins, not because of ‘the technology’, but because no one will accept their worthless fiat for payments. Contrary to popular belief, good money drives out bad. This “driving out” has started as a small fiat bleed. It will rapidly escalate into Class IV hemorrhaging due to speculative attacks on weak fiat currencies. The end result will be hyperbitcoinization, i.e. “your money is no good here. Bitcoins are not just good money, they are the best money. The Bitcoin network has the best monetary policy and the best brand. We should therefore expect that bitcoins will drive out bad, weak currencies. My own prediction is that slow bleed has been accelerating and is only the first step. The second step will be speculative attacks that use bitcoins as a platform. The third and final step will be hyperbitcoinization.”
Different representations of Canadian dollars compete to be used as payment methods (cash, bank balances, PayPal balances, closed-loop prepaid cards, open-loop prepaid cards, etc.) and that the winner will be the one that has the best Bitcoin saleability, i.e. which can be most easily sold for Bitcoin at a moment’s notice.
We’re very proud to provide this alternative payment method to Canadians in a time where the banking system is falling deeper into crisis, especially as the Canadian dollar is demonstrating itself to be one of the most pointless and weakest currencies that nobody really wants to hold.
Finally, we’re very happy to be partnering with Aquanow, our recommended institutional liquidity provider for high-volume BTC-CAD trading. They will accept Liquid CAD deposits and withdrawals as being interchangeable with Canadian dollars. We hope that Liquid CAD will become the standard representation of Canadian dollar value among Canadian Bitcoin users.

Liquid Bitcoin (L-BTC) integration

In addition to Liquid CAD, Bull Bitcoin is also announcing that Liquid Bitcoin (L-BTC) payments are now supported interchangeably with Bitcoin transactions for all Bull Bitcoin services. This means that our users can buy, sell and spend L-BTC instead of BTC.
Canadian Bitcoin traders can purchase L-BTC from BullBitcoin.com and fund their international trading accounts with L-BTC using ultra fast and cheap confidential transactions. They can also cash-out their Bitcoin balance as L-BTC from these platforms and sell those L-BTC for fiat on Bylls.com, avoiding risky and expensive international wire transfers to unknown and untrusted foreign banks.
The transactional benefits of L-BTC are very potent:
Disclaimer: Liquid Bitcoin (L-BTC) is not the same as Bitcoin (BTC). L-BTC Liquid Network assets are IOUs for Bitcoin held in a multisignature contract by the Liquid Network federation. The custody of the underlying Bitcoin is managed by a decentralized network of 15 members which process transactions and withdrawals from the multisignature contract according to the Liquid Federation protocol rules.

Liquid CAD detailed overview

Peer-to-peer prepaid payments by Bull Bitcoin

Liquid CAD is a non-custodial prepaid payment system denominated in Canadian dollars. Units of Liquid CAD (L-CAD) consist of vouchers issued on the Liquid Network as confidential bearer assets that can be transacted peer-to-peer using a Liquid wallet. Users acquire Liquid CAD by withdrawing their account balance out of the Bull Bitcoin, by purchasing Liquid CAD with Bitcoin on Bull Bitcoin, by using the Liquid CAD withdrawal method on other Bitcoin liquidity providers such as Aquanow or by accepting L-CAD as method of payment.

A new payment method in Canada

Liquid CAD can be used by anyone to send and receive payments denominated in Canadian dollars. Because of the permissionless nature of the Liquid Network, Bull Bitcoin cannot prevent Liquid CAD from being traded on secondary markets. Merchants, individuals and institutions must accept that only Bull Bitcoin can guarantee redemption of the L-CAD and that this redemption will be exclusively paid out in Bitcoin. Accepting Liquid CAD as payment is, in effect, the same as accepting gift cards as payment. However, Bitcoin being the most liquid commodity on the market, it can be transformed into any other currency easily for example using services such a Bylls which allow Canadians to pay all their utility bills, send bank transfers to third parties or sell Bitcoin to their bank account.

Making Canadian dollars bleed into Bitcoin

The purpose of Liquid CAD is to facilitate the transfer fiat in the context of the purchase and sale of Bitcoin and providing innovative new services that help Bitcoin users hedge the value of Canadian dollars against Bitcoin in the context of their commercial transactions. Our goal is to create a payment method that is specifically targeting Bitcoin users that wish to liquidate Canadian dollar payments for Bitcoin. Our mission is to accelerate the phenomenon known as “fiat bleed” whereby Canadians will gradually abandon inferior money (such as the Canadian dollar) for the superior Bitcoin alternative. Every Liquid CAD issued will ultimately be exchanged into Bitcoin. We are excited for the day Liquid CAD will be made obsolete by the inevitable hyperbitcoinization of the Canadian economy.

Regulation: is Liquid CAD a stablecoin?

Liquid CAD is not a general-purpose “stablecoin”. It is a closed-loop Bitcoin prepaid card. It can exclusively be redeemed for Bitcoin on the Bull Bitcoin platform (or at affiliated merchants). Bull Bitcoin is the only counterparty, and it cannot be redeemed for a canadian dollar payment. It is substantively the same as Canadian Tire money. Unlike stablecoins, Bull Bitcoin makes money with L-CAD by driving the sales of Bitcoin on its platform, and doesn’t collect interest on the deposits of Liquid CAD users.
The purchase of Liquid CAD with Canadian dollars is regulated in the Province of Quebec as a prepaid card under the Consumer Protection Act and the Regulation respecting the application of the Consumer Protection Act Consumer Protection Act which define a prepaid card as “a certificate, card or other medium of exchange that is paid in advance and allows the consumer to acquire goods or services from one or more merchants”.
The purchase of Bitcoin using Liquid CAD is regulated in Canada by the Financial Transactions and Reports Analysis Centre of Canada under the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (S.C. 2000, c. 17).

Counterparty risk

Like all other closed-loop prepaid instruments, Liquid CAD has counterparty risk. The owners are trusting that they will eventually be able to use Liquid CAD as a payment method on the Bull Bitcoin platform to fund their account and purchase Bitcoin. When a Bull Bitcoin user withdraws his Bull Bitcoin account balance as an L-CAD token, the Canadian dollars he used to fund this balance remains in our possession in the same manner as regular Bull Bitcoin vouchers. These funds are used to execute Bitcoin purchases when L-CAD owners decide to redeem their L-CAD for Bitcoin. In essence, each L-CAD is “backed” by the Canadian dollar deposit of the user that withdraws it from the platform in the first place.

Benefits of using and accepting Liquid CAD for payments

Irreversible, non-custodial and no bank required

Liquid CAD payments cannot be charged back, cancelled, delayed or frozen. There is no intermediary between the sender and the recipient. It is a bearer asset: whoever owns the keys owns the coins. It is a perfect way to accept payments or transact securely without depending on banks and payment processors. Canadians can use Liquid CAD to purchase Bitcoin and then use Bylls.com to pay billers, personal payees or simply sell Bitcoin to their bank account.

Fast transaction and cheap fees

Liquid Network transactions are sent and received instantly and require 1 minute for settlement. Transaction fees paid using Liquid Bitcoin can be as low as 300 satoshis per transaction (a few cents). In order to benefit from these cheap fees, make sure to download the latest version of the Elements software and ensure that the minimum transaction fee is set at 100 satoshis per kilobye. It only takes a few minutes to set up a free Liquid Network wallet, such a Green Wallet by blockstream.

Confidential transactions

Unlike Bitcoin, transactions between the sender and the recipient are encrypted. It is impossible for third parties observing Liquid CAD transactions on a block explorer to determine the amount of the transaction. In addition, it’s also impossible to even know you are using Liquid CAD, since the data identifying the asset itself is also encrypted!

What are the use-cases of Liquid CAD?

Buying and selling Bitcoin

The primary use-case of Liquid CAD is to make it easier to buy and sell Bitcoin on the Bull Bitcoin platform. By withdrawing their balance from Bull Bitcoin, users are reducing some (but not all) of the custody risk associated with keeping fiat currency on an exchange. For example, use Liquid CAD to create your own non-custodial dollar-cost-averaging schedule!

Onboarding new Bitcoin users

New users can be overwhelmed by the experience of dealing with banks to buy Bitcoin (and the heavier KYC process of account funding). You may be tempted to buy Bitcoin for them, but that will impose a lot of burdens on you. It’s much easier to set them up with a Green wallet, send them Liquid CAD and show them how to use Bull Bitcoin! They decide when is the right time for them to invest, with a lower KYC burden.

Hedging Bitcoin price

You may believe the price of Bitcoin will go down in the short term, but you still want to hold Bitcoin in the long term. Normally you have two options: short the Bitcoin price (very risky!) or sell your Bitcoin and receive Canadian dollars in your bank account (inconvenient!). By selling your Bitcoin for Liquid CAD, you can lock in the value of Bitcoin right now and buy them back later without needing to use your bank account or taking risks with leverage.

Accepting payments

As a merchant, you want to receive the settlement of payments in Bitcoin. But this imposes a burden on your customers, which have to deal with the Bitcoin price volatility when they are paying you. Ask your clients to pay you with Liquid CAD, and you can get the settlement with Bitcoin on your own terms.

Payroll and suppliers

What if your staff or suppliers want to get paid in Bitcoin? It can be very difficult, because this means you are effectively buying Bitcoin on their behalf. Instead, you can pay them in Liquid CAD and let them deal with the process of choosing the exchange rate and using their own wallet. Let them deal with the tax burden, exchange rates and Bitcoin wallet security.

List of Bull Bitcoin Liquid Network features

Withdraw account balance as L-CAD

This is conceptually the same as “buying” Liquid CAD with your account balance. We call it “Withdrawing L-CAD” because on the Bull Bitcoin platform, we consider L-CAD and CAD to be interchangeable and fungible.

Fund account balance with L-CAD

To redeem Liquid CAD for Bitcoin, users need to first fund their account by selecting the “Deposit L-CAD” payment method. Bull Bitcoin users must always fund their account first before buying Bitcoin, and then purchase Bitcoin with their account balances. Reminder: account balances cannot be withdraw as fiat payments, but can later be withdrawn again as L-CAD.

Sell Bitcoin for L-CAD

You can sell Bitcoin and receive Liquid CAD payments instead of a bill payment, personal payee payment or bank payment. As soon as the Bitcoin transaction is confirmed, the Liquid CAD transaction is sent to the address you provided.

Liquid Bitcoin (L-BTC) and Bitcoin interchangeability

For every service which involves a Bitcoin payment, the user can substitute traditional Bitcoin payments for Liquid Bitcoin payments. This includes:

A REVIEW ON LEASEHOLD DECENTRALIZED PLATFORM

A REVIEW ON LEASEHOLD DECENTRALIZED PLATFORM

https://preview.redd.it/myag8bgerrt41.jpg?width=2226&format=pjpg&auto=webp&s=f2770899309d92ca6acab5b1c5fdcc76f69778a2
INTRODUCTION
In the world today, there are many upcoming blockchain projects with great potentials, each aiming to bring a change to what we know and see in different systems be it in the healthcare industry, financial industry and so on. It is worthy to know that blockchain technology has contributed a lot to the development of many projects owing to its features such as decentralization, tokenization, use of smart contracts etc. Also, in addition to being based on blockchain, many platforms have different consensus algorithms which are believed by the team to help them in achieving their aim. With this being said, there is a blockchain platform known as LEASEHOLD, which aims to bring a change in the property industry.
https://preview.redd.it/a55t1e0drrt41.jpg?width=2048&format=pjpg&auto=webp&s=4ba13f6477ad66c90a2855688e63d60ddb30531d
A REVIEW ON LEASEHOLD PLATFORM
A review helps many potential investors have a feel or glance of what a particular project or platform is all about, before proceeding to read further via the project's whitepaper etc.
  1. The first and foremost thing to know about Leasehold platform is that it is decentralized that is to say, it is based on blockchain. Leasehold is also a profit-sharing business or platform with the sole purpose of sharing rental income via tokenization brought about by blockchain. In the same way, it is good to know that, the Leasehold platform aims to be a valuable one and to achieve this, sees it fit to ensure their token holders are always comfortable hence the idea of rewards being in the form of buy-back and burn; with this strategy, the Leasehold platform take the acquired profits, buys back its tokens from the market and burn them. In other ways, Leasehold token is a Deflationary token which will continue to be bought and burnt as the platform ensures strict growth policies are followed.
  2. Like earlier stated, there are many blockchain projects with different consensus algorithms such as Proof-of-Stake, Proof-of-Work etc, in the case of Leasehold, it will be based on Delegated Proof-of-Stake (DPOS). This DPOS is of the idea that delegates within the platform can create blocks, these delegates are trusted and as such selected to be active within the platform in addition to the fact they secure the chain while getting their rewards which is strictly based on a good performance.
  3. In the blockchain space today, there is a known issue with most platforms and that is the issue of slow transactions etc, thus to stand out from this, the Leasehold team ensured the platform is written in JavaScript, through this way, allowing for fast processing of all functions and services such as transactions, payments and accounting. Also, to ensure efficient services, the Leasehold platform was forked from Lisk, the aim of this is to run as the first Lisk Side-chain through this way having its own Decentralized Exchange (DEX) thereafter.
  4. Talking about a decentralized exchange, it offers more security because, in the crypto space, there are many exchanges that have been hacked, exit scam with funds as well as closing accounts without reason. Therefore, Leasehold will sure have its own because the team wants to offer a secure, safe, trustworthy and reliable platform for trading of LSH tokens. When trading in Leasehold platform's DEX, there will be no malicious acts but instead a good level of trust and transparency.
  5. Another point as to why Leasehold is worthwhile is the fact that it makes it possible for users to partake in profit-sharing without owning properties physically, nor is there a need to identify themselves. In view of this, Leasehold is working towards taking huge advantages of the tourist industry, everyday living industry etc since it has been proven that booking platforms grow with more than double the users from the previous years. With this move, as a user, there is an opportunity to profit by owning the property, while with Leasehold, everything is simplified leading to owning a portion of profits.
  6. Another wonderful attribute of Leasehold platform is that token holders are carried along in the development of the platform, in this case, they are always presented with updated happenings which includes buy-back details, acquisition of properties etc.
  7. Since security is paramount in Leasehold platform, the team created a hub, which will make it possible for token holders to securely store their tokens in their wallet. This wallet is connected directly to the Leasehold network.
  8. There are many projects already in the crypto space which supports mining and same is the case with Leasehold. Leasehold will have a real-time data pool bearing all the financials of the platform's earnings. It will also display a list of the current buy-back funds which will be used for buy-back and burn purposes.
  9. Currently, many people in the world are limited when it comes to using of cryptocurrencies and this is where tokenization comes to play; that is, with tokenization, many people in the world will be free and able to buy crypto easily. With this in mind, in the Leasehold platform is tokenization as well, with tokenization of LSH tokens, people from all over the world will be able to take part in profit-sharing from the Leasehold short term rental markets. This is profitable because a study has shown that, short term rental markets are now booming all over the world because there is no need putting up large amounts of capital at once, which many individuals do not have or have access to.
  10. There are two methods of property rental in Leasehold platform which is developed to accommodate different types of users; a. Property rental of non-owned apartments: This is a method where the Leasehold team will accept the responsibility of running apartments for homeowners which will be at an agreed amount. In this case, the team will use their marketing strategies and booking system methods to ensure the best of services is offered to homeowners while on the other hand, this will also help Leasehold to acquire constant funding for its buybacks. b. Property rental of owned properties: In this method, the Leasehold team will strive to achieve the maximum amount of returns since all profits will belong to the company at the same time distributed to the buybacks. Furthermore, from the profits made, Leasehold will continue buying property on the open market while renting it out using its specially designed cross-platform method.
  11. Just like there are blockchain platforms which sought for funding before continuing building their platform, same is with Leasehold. The team will carry out 5 stages of ITO’s with the aim of raising enough funding so as to acquire small apartments thus starting the renting process and partner site setups. According to the team, the reason for these stages of ITO is that each stage will allow the Leasehold platform to acquire and set up the working business model that will make the buy-back and burn process possible. The end result of this is, Leasehold will be in a position to be free from cryptocurrencies volatility as well as being far bear markets. Leasehold Initial Token Offering (ITO) has started already and stipulated to end by May 2020. Read more on (ITO). (It is wise to make your own research before investing or participating in any token sale.)

WHY LEASEHOLD IS WORTHY OF ATTENTION
a. The Leasehold team aims for success thus setting strict growth policies which will make it possible for the platform to always acquire more and more property in its life cycle.
b. By allowing ownership of profits to take place in the property rental industry, Leasehold succeeds in bringing liquidity. To make it more interesting, people can buy and sell the rights to profits without having to pay the unnecessary charges of Deed registration and property acquisition.
c. In the world today, the cryptocurrencies are gaining more attention which is seen in Airbnb now accepting Bitcoin, with this in mind, the Leasehold team believes that more platforms are likely to follow hence creating its very own booking system within the ecosystem that will allow users to book holidays with LSH token.
d. Leasehold platform is all about success and growth and with this in mind, the team has already 4 signed contracts for 4 separate apartments which started this month (April 15th). Not only that, but the team is also on the verge of signing more as time goes by.
e. Leasehold has many partners including; i. Booking.com. ii. Airbnb. iii. NightsBridge. iv. HouseME. v. HomeAway. vi. Bookme. vii. Airdna. Read more on partners.
f. For security sakes, and in order to stand out as well, Leasehold created its own wallet which is available and active on different operating systems such as Windows, Mac etc. Steps; i. Download your desired Leasehold Wallet application from the link. ii. Install. iii. Use the option "Create an account" to create an account. Most importantly, remember to save the passphrase, which will enable you as the owner to be able to access the wallet in the future. iv. Login to have a feel of what the wallet looks like.
g. Leasehold token has the ticker LSH, it was forked from Lisk as well as being the first "Lisk Side-chain off Lisk" with a total supply of 100,000,000. Owing to what Leasehold token is backed by, the tokens will be appropriate for trading, holding and booking apartments in the near future. In the same way, to be transparent as regards its buybacks, the necessary information will be available to the public in the form of e-mail and website updates, through this way, users will be able to keep track of the entire platform's Income.
h. Hardly can anyone invest in what he won't profit from; in the case of Leasehold, the team will use the funds generated for property acquisition this means that there will be a strong profitable business built by the team. With this move by the Leasehold team, token holders will grow together with the platform while profiting as well.

Top 7 unique, high-potential cryptocurrencies of 2019 that are actually innovating the space

Right now, the top 20 has 2 forks of Bitcoin, Tether, an exchange's token, Ethereum Classic, and a few other projects that make this space look far less serious than it really is. On the other hand, you have many great projects out of the top 20 with huge potential going forward. The purpose of this post is to discuss the cryptocurrencies that I believe are exciting, different, and already have (or are extremely close to having) a working project. These are the projects that actually keep my faith alive in crypto among all the other BS out there. I'm hoping to outline a few projects you know, as well as some smaller ones. I will exclude Bitcoin, Ethereum, and XRP from this list, as everyone knows them already and what they do. This is NOT MEANT TO BE AN ALL-INCLUSIVE LIST - that means I'm definitely missing some projects. However, these are some of the projects I believe will make seriously large contributions to the space going forward.
1 - Nano. Reddit already shills the hell out of this coin, and it's for good reason. Nano is the single fastest and cheapest (100% free) P2P digital currency in the space, period. There's something to be said about sending somebody 50 Nano and them receiving EXACTLY 50 Nano, not 49.999 or something similar. Nano is an actual innovation in the space, with a very different codebase than other coins. It uses a block lattice (instead of using a blockchain), which is an incredible invention, and is reminiscent of the kind of innovation that ETH first offered for blockchain applications in 2015 - but for digital cash. Nano feels like what Bitcoin should have been from Day 1. Download the mobile app/create a web wallet and send some back and forth between the two - you'll understand why people are so bullish on this coin once you've tried it out for yourself.
2 - Monero. If any coin most clearly resembles the fungibility and privacy of using physical cash, it's Monero. It's the only major coin that is fully private by default, 100% of the time. The recent updates over the past few months have made Monero extremely cheap and fast to use, and if you haven't tried it out, I'd highly recommend it (MyMonero's web wallet is excellent https://wallet.mymonero.com). There's no denying this coin's potential to shape the space in the future as the top privacy coin. Monero has also proven to be highly resistant to bear trends, holding its price better than nearly every other top 40 coin in the last bear market. Lastly, the team is extremely competent and makes real innovations to this coin - between making transactions fully private, cost reduction/speed upgrades, and forking away from ASIC mining, this team has proven that they are little talk, ALL action, and committed to constantly improving this cryptocurrency.
  1. Augur - This decentralized betting platform was one of the first Ethereum dapps ever planned, and took nearly 3 years to come to fruition. It is one of the most well-made, useful dapps running on Ethereum right now and has real users making markets every single day. You can bet on pretty much anything using Augur, and it's actually completely decentralized - meaning no third parties or governments who are unhappy with the content or types of bets being placed - can shut this dapp down. It does have a few issues for sure, but I am confident that they are minor and will be resolved in time as this market continues to mature.
  2. Lisk - Though the project has seen many delays in its time, the Alpha SDK - their biggest innovation - is just about to launch. Lisk will be the first project to really bring sidechains for dapps into the cryptocurrency space, and this is a big deal. It's not just another dapp platform - these sidechains allow for much more customization than simply running a dapp on Ethereum, Tron, or EOS. Dapps can be written in pure Javascript, a language that every software developer knows, and the dapps themselves won't be held back by many of the issues that Ethereum has (average-slow network speed/congestion issues, etc). Not to mention, their team is massive (30+), they have plenty of funding and the price is very low right now ($2, with an ATH of over $35).
  3. IOTA - No matter what you think of this coin, IOTA's tangle is undeniably different. It's DAG-like technology is refreshing to see in a space where 98% of coins are just clones/forks of other coins - even if it doesn't work the way it should yet. It's possible that the removal of blocks and instead creating a tangle of transactions where every node in the network helps to power future transactions could allow for scaling beyond what current blockchains offer.
  4. BitTorrent - I really hesitated to list this one. Do I agree with the way Justin Sun markets and overhypes every small meeting or minor project development? Of course not. However, there is no denying that this token will expose a TON of new users to cryptocurrency for the first time - arguably more than any other dapp token. BitTorrent, the application, is already being used by millions of users, and there's no denying that. This is a rare situation and no other cryptocurrency dapp has anywhere near the user count that this BitTorrent has. While I don't love Tron in general... it is largely an Ethereum clone with few advantages other than added hype...BTT is guaranteed to at least see some real-world usage and it might be good to own a few tokens.
  5. Upfiring - If you like the idea that BitTorrent is putting forth (rewarding seeders), Upfiring is that exact idea - but their dapp is literally already out and nobody knows about it yet. I hesitated to list this project due to the low market cap, but it just might be one of the most useful dapps out there and one of the best uses of smart contracts. The dapp is awesome - super sleek and easy to use. In terms of high potential projects, this one is huge with around a 2 million USD market cap and really could explode at any time imo. You can download their dapp right now and share files on the blockchain, set a price in UFR for your files and earn crypto when others download them. Torrenting is one of the areas that I believe crypto will make a big impact in, since rewarding seeders is an excellent use-case to incentivize file-sharing. With an ATH of 40 million, it has reached 20x the current market cap before, so the price and hype level is currently low.
Major projects to watch out for due to being overvalued or other significant red flags (please don't downvote this post if you disagree with these - instead, let us know why you disagree in the comments):
1 - Litecoin. I'd certainly agree it should be in the Top 50 due to its fame status, but the #4 position is ridiculously high for a coin like this. Put simply, there is simply no major use case for this coin. If you wanted to use something as cash, Nano and even Bitcoin Cash are arguably both better options. At least Bitcoin serves as the standard for markets on exchanges. Remember that the creator of this coin has literally sold all of it as well - while arguably a smart move on his part, it's something to keep in mind.
2 - Binance Coin. Regardless of the fact that it is Binance, and Binance is great, this coin's entire value is based on a 100% CENTRALIZED business. That's a big deal. This means if something ever happens to Binance, for whatever reason, BNB's value will directly be affected as a result. In addition, a 4.5 BILLION dollar market cap for an exchange token is just a ridiculous market cap in general, even if it is Binance. Props to Binance for making this token so successful, though.
3 - Stellar. This is a big one, and I know I'm going to take some heat for listing this, so let me clarify. I really like what Stellar is doing with payments, for sure, but one thing that makes that all null and void from an investment standpoint - Stellar's team owns over 80% of the entire Stellar coin supply. Let that sink in for a second. 19,331,690,041 XLM is circulating among every single Stellar holder, while the team themselves holds 85,710,809,041 XLM. People tend to ignore this fact for some reason, but it's unfortunately a huge deal and requires that you put a ton of trust in Stellar's team not to casually sell millions of dollars worth of their XLM whenever they want more money. How would you feel if Vitalik owned 400,000,000 ETH? That's the same ratio to what the Stellar team owns. There's also been a ton of sketchy things that have happened with the team selling off millions of dollars worth of coins in 2017/early 2018 - you can search those in the search bar to read up on those incidents where users here tracked those transactions. Lastly, Stellar is a fork of Ripple. Not that this is a bad thing necessarily, but it's something to keep note of.
4 - Bitcoin SV. Yeah, it's pumping right now. Who cares, so are lots of coins. Ignore it, and maybe it will go away. This coin once again serves no real purpose and has no place being the #8 cryptocurrency with how many great projects are sitting below it.
5 - Ethereum Classic. This coin has already been 51% attacked SUCCESSFULLY, and it's value has gone up since then. In addition, no changes have been made to the coin to prevent such an attack in the future, and none are planned. No hard forks will happen to improve this coin, ever...that's because Ethereum Classic's main value proposition is immutable and irreversible transactions, Ironic - because the 51% attack showed that transactions on this chain are actually the exact opposite of this. Obviously, this coin should be avoided.
And before you ask, why did I leave out... -Cardano: Interesting project but too far away from releasing their smart contracts to mention in this post. In addition, market cap is extremely high for not having a working product out yet
-Tron: A hyped-version of Ethereum with few differences. Not necessarily bad, but not innovative enough to mention from a technological standpoint. I won't comment on their marketing tactics...
-Vechain: It remains to be seen whether this use-case will ever play out using a public blockchain like this with real businesses. Certainly one to keep an eye on, but as of right now it's not being used on any sort of large scale
-Qtum: Still has yet to find a real niche over projects like Ethereum, Tron, and EOS
-EOS: Raised billions of dollars in their ICO but their platform still has many issues. There are some decent developments like Everipedia on it, but overall I decided to leave it out due to once again, not offering anything THAT innovative to the space, and the lack of decentralization (EOS team can freeze transactions)
I'll update the top list as well if anyone provides me with good projects that I may have missed out on here!

To everyone rushing back into BTC from altcoins: What matters is that you learn why Bitcoin needs to be conservative in its development.

Over the past year, the prevailing thought among many in the cryptocurrency communities is that bitcoin is not keeping up with other coins. That somehow bitcoin was being intentionally crippled, or that the developers did not know what they were doing. As we are seeing with the bitcoin dominance going up, that prevailing thought was wrong. The coins who were supposedly going to kill bitcoin have been all but abandoned in many cases. Many others are in the process of dying a slow death (which may take years to fully play out).
To everyone who went heavy on these coins and sold all of their bitcoin, but are now coming back: Welcome back. We are glad to have you. But before you pretend like everything is great with bitcoin again, it's important to realize why you were wrong.
But first let's go back a few years. In 2015, I was a staunch big blocker. I want to share a post made during this time that I initially downvoted. (The reason I know this is because after a certain number of months/years, reddit does not let you change whether you upvoted/downvoted something). I downvoted it because it went against my biases which had already been built up around the scaling decision, and later I came back to this post after being referred to it again. The 2015 version of me had only been in Bitcoin for 2 years, and was disillusioned with what I thought bitcoin was. And not what it actually was, or what its limitations were. The 2018 me now realizes why I was wrong, but back then I spent far too much time thinking I had it all figured out. The post that I downvoted, is as relevant today as it ever was:
A trip to the moon requires a rocket with multiple stages or otherwise the rocket equation will eat your lunch... packing everyone in clown-car style into a trebuchet and hoping for success is right out.
A lot of people on Reddit think of Bitcoin primarily as a competitor to card payment networks. I think this is more than a little odd-- Bitcoin is a digital currency. Visa and the US dollar are not usually considered competitors, Mastercard and gold coins are not usually considered competitors. Bitcoin isn't a front end for something that provides credit, etc.
Never the less, some are mostly interested in Bitcoin for payments (not a new phenomenon)-- and are not so concerned about what are, in my view, Bitcoin's primary distinguishing values-- monetary sovereignty, censorship resistance, trust cost minimization, international accessibility/borderless operation, etc. (Or other areas we need to improve, like personal and commercial privacy) Instead some are very concerned about Bitcoin's competitive properties compared to legacy payment networks. ... And although consumer payments are only one small part of whole global space of money, ... money gains value from network effects, and so I would want all the "payments only" fans to love Bitcoin too, even if I didn't care about payments.
But what does it mean to be seriously competitive in that space? The existing payments solutions have huge deployed infrastructure and merchant adoption-- lets ignore that. What about capacity? Combined the major card networks are now doing something on the other of 5000 transactions per second on a year round average; and likely something on the order of 120,000 transactions per second on peak days.
The decentralized Bitcoin blockchain is globally shared broadcast medium-- probably the most insanely inefficient mode of communication ever devised by man. Yet, considering that, it has some impressive capacity. But relative to highly efficient non-decentralized networks, not so much. The issue is that in the basic Bitcoin system every node takes on the whole load of the system, that is how it achieves its monetary sovereignty, censorship resistance, trust cost minimization, etc. Adding nodes increases costs, but not capacity. Even the most reckless hopeful blocksize growth numbers don't come anywhere close to matching those TPS figures. And even if they did, card processing rates are rapidly increasing, especially as the developing world is brought into them-- a few more years of growth would have their traffic levels vastly beyond the Bitcoin figures again.
No amount of spin, inaccurately comparing a global broadcast consensus system to loading a webpage changes any of this.
So-- Does that mean that Bitcoin can't be a big winner as a payments technology? No. But to reach the kind of capacity required to serve the payments needs of the world we must work more intelligently.
From its very beginning Bitcoin was design to incorporate layers in secure ways through its smart contracting capability (What, do you think that was just put there so people could wax-philosophic about meaningless "DAOs"?). In effect we will use the Bitcoin system as a highly accessible and perfectly trustworthy robotic judge and conduct most of our business outside of the court room-- but transact in such a way that if something goes wrong we have all the evidence and established agreements so we can be confident that the robotic court will make it right. (Geek sidebar: If this seems impossible, go read this old post on transaction cut-through)
This is possible precisely because of the core properties of Bitcoin. A censorable or reversible base system is not very suitable to build powerful upper layer transaction processing on top of... and if the underlying asset isn't sound, there is little point in transacting with it at all.
The science around Bitcoin is new and we don't know exactly where the breaking points are-- I hope we never discover them for sure-- we do know that at the current load levels the decentralization of the system has not improved as the users base has grown (and appear to have reduced substantially: even businesses are largely relying on third party processing for all their transactions; something we didn't expect early on).
There are many ways of layering Bitcoin, with varying levels of security, ease of implementation, capacity, etc. Ranging from the strongest-- bidirectional payment channels (often discussed as the 'lightning' system), which provide nearly equal security and anti-censorship while also adding instantaneous payments and improved privacy-- to the simplest, using centralized payment processors, which I believe are (in spite of my reflexive distaste for all things centralized) a perfectly reasonable thing to do for low value transactions, and can be highly cost efficient. Many of these approaches are competing with each other, and from that we gain a vibrant ecosystem with the strongest features.
Growing by layers is the gold standard for technological innovation. It's how we build our understanding of mathematics and the physical sciences, it's how we build our communications protocols and networks... Not to mention payment networks. Thus far a multi-staged approach has been an integral part of the design of rockets which have, from time to time, brought mankind to the moon.
Bitcoin does many unprecedented things, but this doesn't release it from physical reality or from the existence of engineering trade-offs. It is not acceptable, in the mad dash to fulfill a particular application set, to turn our backs on the fundamentals that make the Bitcoin currency valuable to begin with-- especially not when established forms in engineering already tell us the path to have our cake and eat it too-- harmoniously satisfying all the demands.
Before and beyond the layers, there are other things being done to improve capacity-- e.g. Bitcoin Core's capacity plan from December (see also: the FAQ) proposes some new improvements and inventions to nearly double the system's capacity while offsetting many of the costs and risks, in a fully backwards compatible way. ... but, at least for those who are focused on payments, no amount of simple changes really makes a difference; not in the way layered engineering does.

If you're made it this far and want to read more, or perhaps from a different perspective, here is another article which influenced me more recently by Melik Manukyan
Lightning Network enables Unicast Transactions in Bitcoin. Lightning is Bitcoin’s TCP/IP stack.
It has recently come to my attention that there is a great deal of confusion revolving around the Lightning Network within the Bitcoin and Bitcoin Cash communities, and to an extent, the greater cryptocurrency ecosystem. I’d like to share with you my thoughts on Bitcoin, Blockchain, and Lightning from a strictly networking background.
To better understand how blockchain and the lightning network work, we should take a step back from the rage-infused battlegrounds of Twitter and Reddit (no good comes from this 😛) and review the very network protocols and systems that power our Internet. I believe that there is a great wealth of knowledge to be gained in understanding how computer networks and the Internet work that can be applied to Bitcoin’s own scaling constraints. The three protocols I will be primarily focusing on in this article are Ethernet, IP, and TCP. By understanding how these protocols work, I feel that we will all be better equipped to answer the great ‘scaling’ question for Bitcoin and all blockchains alike. With that said, let’s get started.
In computer networking, the two most common forms of data transmission today are broadcast and unicast. There are many other forms such as anycast and multicast, but we won’t touch up on them in this article. Let’s first start by defining and understanding these data transmission forms.
Broadcast — a data transmission type where information is sent from one point on a network to all other points; one-to-all.
Diagram: Broadcast Data Transmission https://cdn-images-1.medium.com/max/800/1*xbgXKepaeHZRqmHWsCb_qw.png
Unicast — a data transmission type where information is sent from one point on a network to another point; one-to-one.
Diagram: Unicast Data Transmission https://cdn-images-1.medium.com/max/800/1*i18TOm6hT_h7UQ8cnt8U_Q.png
Based on our understanding of these types of data transmission forms, we very quickly discover that blockchain transactions resemble Broadcast-like forms of communication. When a transaction is made on the Bitcoin network, the transaction is communicated or broadcasted to all connected nodes on the network. In other words, for a transaction to exist or happen in Bitcoin, all nodes must receive and record this transaction. Transactions on blockchains work very similarly to how legacy, ethernet hubs handled data transmissions.
A long time ago, we relied on ethernet hubs to transfer data between computers. Evidently, we discovered that they simply did not scale due to their limited nature. Old ethernet hubs strictly supported broadcast transmissions, data that would come in through one interface or port would need to be broadcasted and replicated out through all other interfaces or ports on the network. To help you visualize this, if you wanted to send me a 1MB image file over a network with 100 participants, that 1MB image file would, in turn, need to be replicated 99 times and broadcasted out to all other users on the network.
In Bitcoin, we see very similar behavior, data (a transaction or block) that comes from one node is broadcasted and replicated to all other nodes on the network. Blockchains similarly to old, legacy ethernet hubs are simply poor mediums to perform data transmission and communicate over. It is simply unrealistic to me as a network engineer to even consider scaling a global payment network such as Bitcoin via Broadcast-based on-chain transactions. Even to this very day, us network engineers take great care and caution in spanning our Ethernet and LAN networks, let alone on a global level.
To put it into perspective, if we were to redesign the Internet by strictly relying on broadcast data transmissions as exhibited in blockchains and ethernet hubs — we would have effectively put every single person, host, and device in the entire world on the same LAN segment or broadcast domain. The Internet would have been a giant, flat LAN network where all communication would need to be replicated and broadcasted to every single device. In you opening up to read this article, every other device on the Internet would have been forced to download this article. In other words, the internet would come to a screeching halt.
In computer networks, the most frequent form of communication relies on unicast data transmissions, or point-to-point. Most of the communication on the internet is routed from one computer to another, we no longer need to rely on blind broadcast transmissions of data with the hopes that our recipient will receive it or see it. We are able to accurately send, route and deliver our messages to our receiving party(ies). We learned that the transfer of a 1MB image file in a broadcast network would require the file to be replicated and broadcasted to every participant on that network. Instead, in a network that supports unicast data transmissions, we are able to appropriately route that image file from source to destination in a clearcut manner.
To me, the Lightning Network is the IP layer of Bitcoin. (I understand that these data transmission forms exist in both Ethernet and IP.) But, I do feel that these analogies help us to better understand these complex and largely abstract ideas: blockchain, lightning, channels, etc.
Let’s take a moment and ignore all explanations and overly simplistic definitions of Lightning that are perpetuated from both sides of the debate for a moment. Instead, lets objectively take a close look at Lightning and determine what we know. What do we know about lightning? It allows us to lock our Bitcoin and form channels with others. What else do we know? We can bidirectionally send and receive transactions between the two points that constitute the channel. What else do we know? We can further route transactions to their correct destination.
Based on these key understanding points, we are able to see that lightning enables unicast transactions in a system [Bitcoin] that previously only supported broadcast transactions. To me, Lightning nodes in Bitcoin are the equivalent of IP hosts — where we can finally conduct or route one-to-one or point-to-point transactions to their appropriate recipients. In traditional IP, we send and receive data packets; in Lightning, we send and receive Bitcoin. IP is what allowed us to scale our small and largely primitive networks of the past into the global giant that it is today, the Internet. In a similar manner, Lightning is what will allow us to scale our global Bitcoin network.
Where Lightning Nodes can be seen as IP hosts, I view Lightning Channels as established TCP connections. On the Internet today, when we try to connect to a website for example, we open a TCP connection to a web server through which we can then download the website’s HTML source code from. Alternatively, when we download a torrent file, we are opening TCP connections to other computers on the Internet which we then use to facilitate the transfer of the torrent data.
And in Lightning, we establish channels with our respective parties and are able to directly [point-to-point] send and receive data (transactions) similarly to TCP. Where Blockchain is similar to Ethernet, Lightning Nodes are our IPs and Lightning Channels our TCP connections.
To conclude, I see many similarities to our pre-existing network technologies and protocols that power our computer network(s) and I feel that we are redesigning the Internet. From a technical point of view, I don’t believe that scaling Bitcoin on-chain will ever work and fear broadcast storm-like events in the future. I welcome our new unicast transaction methods enabled by the Lightning Network. Even more so, I am excited for the ‘web’ moment in Bitcoin.
While everyone has their eyes fixed on blockchain technology, I look towards Lightning. Lightning is the TCP/IP stack of Bitcoin. Lightning is where we will transact on. Lightning is where everything will be built on. Lightning is what will power and enable our applications and additional protocols and layers. With this said, what is to become of the main Bitcoin blockchain? It will and should remain a decentralized, tamper-proof, immutable base or foundation layer which will provide us with cryptographic evidence of what is a Bitcoin.
Some individuals and groups within our communities and ranks spread fear and warn us of false narratives of “lightning hubs”, but fail to grasp that their scaling approach of on-chain transactions only pushes us in the direction of an actual (ethernet) hub design. If Bitcoin loses decentralization on its base layer, then we will lose Bitcoin. The past 9 years of work will have only resulted in a large, centralized broadcast hub with only a few remaining with the ability to operate such a monstrosity.
I wrote this article with hopes that it will help clear up the ongoing confusion about Bitcoin, Blockchain, and Lightning. It is designed to help better explain Blockchain and Lightning through analogies to concepts that we may be more familiar with. I also wrote this very quickly and it may contain typos. If you notice any typos, please bring it to my attention.

1 Introduction to the Bitcoin System

1.1 Introduction and General Description

There are many definitions and descriptions of Bitcoin. Some describe it as an innovative virtual or crypto currency, some as the system for peer-to–peer electronic cash payment transactions, and some others as decentralized platform and infrastructure for anonymous payment transactions using any type of crypto currency.
In this Report we will adopt the concept that the Bitcoin system is a payment system. It has its own features, its own currency, its own protocols and components, and with all that Bitcoin supports payment transactions. In other words, the core function of the Bitcoin system is to support payments between two parties – the party that makes a payment and the party that receives the payment.
Based on the original concept and the description of the Bitcoin [Bitcoin, 2016], “it is a decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: transaction management and money issuance are carried out collectively by the network”.
The system is decentralized since its supporting platform blockchain, comprises an infrastructure of multiple distributed servers, mutually linked by an instantaneous broadcasting protocol. Users perform transactions within the open and distributed community of registered users. Digital currency used in the system is not electronic form of fiat currency, but a special form of the currency generated and used only within the Bitcoin system. This concept is based on the notion that money can be interpreted as any object, or any sort of record, that is accepted as payment for goods and services and repayment of debts in a given country or socio-economic context. Bitcoin system is designed around the idea of using cryptography to control the creation and transfer of money, rather than relying on central authorities.
There are several important requirements when making any type of payment and with any currency. The best example of a “perfect” payment transaction that meets all these requirements is payment using cash over-the-counter. When a consumer pays to a merchant using cash over-the-counter, such transaction satisfies all requirements and expectations of both parties. First, the transaction is instantaneous, as the paper bill is transferred hand-to-hand, from the consumer to the merchant. The transaction is cheap, in fact there is no overhead charge to perform transaction, so the merchant receives the full amount. The transaction is irreversible, what is the property beneficial to merchants. The transaction is legal, as the merchant can verify the legality of the paper bill. And, finally, the transaction is anonymous for the consumer as he/she does not need to reveal his/her identity.
The only “problem” with cash over-the-counter is the cash itself, as using and handling cash has many disadvantages.
Bitcoin concept and system solves all issues and problems with the use of cash, but at the same time provides all advantages when performing transactions using digital and communication technologies. So, paying with Bitcoins is effectively payment transaction that uses “digital cash over-the-counter”. The concept of the Bitcoin system provides all advantages and benefits mentioned above with payments using cash over-the-counter, but eliminates the problems of using cash. That is the reason why Bitcoins are often referred to as “digital cash”.
One of significant features of payments using cash over-the-counter is that there are no third parties to participate or assist in the execution and validation of a transaction. This feature makes Bitcoin transactions very efficient and also very cheap to perform. Other types of todays payment systems, for instance using bank-to-bank account transfers or using bankcards, use many additional intermediate parties and use very complicated background infrastructure to validate and clear payment transactions. These infrastructures are complex to establish and operate, they are expensive, and they are vulnerable to attacks and penetrations by hackers. Bitcoin does not use such complex infrastructures, what is the reason that its transactions are efficient and cheap. An additional problem with third-party transaction players is that transaction parties must put the complete trust in all these parties without any means to verify their functionality, correctness, or security.
Bitcoin system uses public-key cryptography to protect the currency and transactions. Logical relationships between transaction parties is direct, peer-to-peer, and the process of validating transactions is based on cryptographic proof-of-work. When performing a transaction, the net effect is that certain amount of Bitcoins is transferred from one cryptographic address to another. Each user may have and use several addresses simultaneously. Each payment transaction is broadcast to the network of distributed transaction processing servers. These servers collect individual transactions, package them into blocks, and send them for validation.
Each block is cryptographically processed by the large number of so called “miners”. They each attempt to create cryptographic hash value that has special form. This is computationally very difficult and time-consuming task, therefore, it is very difficult to perform and repeat. Individual blocks are validated using cryptographic processing procedures that require substantial amount of work and computing power.
Approximately an hour or two after submitting the transaction for validation, each transaction is locked in time and by cryptographic processing by the massive amount of computing power that was used to complete the block. When the block is validated, it is added to the chain of all previous blocks, thus forming a public archive of all blocks and transactions in the system.
One of the most important problems with uncontrolled digital currency, where there are no third parties to validate and approve transactions, is so called double spending. Since the currency is digital, stored at user’s local workstations, in mobile phones, or on network servers, it can be easily copied and sent to multiple recipients multiple times.
Bitcoin system solves this problem with a very interesting approach. It is the first effective example of the solution for the double-spending problem without the need for assistance of any third party. Bitcoin solves this problem by keeping and distributing an archive of all transactions among all the users of the system via a peer-to-peer distribution network. Every transaction that occurs in the Bitcoin system is recorded in that public and distributed transactions ledger. Since the components in that ledger are blocks with transactions and the blocks are “chained” in time and in a cryptographic sequence, the ledger in the Bitcoin system is called blockchain.
That full blockchain of all transactions that were performed in the Bitcoin system before the specific transaction can be used to verify new transactions. The transactions are verified against the blockchain to ensure that the same Bitcoins have not been previously spent. This approach eliminates the double-spending problem. The essence of the verification procedure for a single transaction in fact is the test of the balance of the sending account. The test is very normal and natural: payment of a certain amount of the currency can be made only of the balance of the outgoing account is equal or larger than the payment amount. Current balance of an account is established by tracing all incoming and outgoing transactions for that account.
The procedure to verify the validity of individual transactions and to prevent double-spending is based on the use of special type of cryptographic protocol called public-key cryptography. With this type of cryptographic systems each user has two cryptographic keys. They are mutually related in the sense that, what ever the one key encrypts, the other key can decrypt. One of the two keys is a private key that is kept secret, and the other key is public key that can be shared with all other users in the system. When a user wants to make a payment to another user, the sender transfers certain amount of Bitcoins from his/her account to the account of the receiver. This action is performed by the sender by creating a payment message, called a “transaction,” which contains recipient’s public key – receiving address and payment amount. The transaction is cryptographically processed by the sender’s private key, the operation called digital signing, and as the result digital signature is created and appended to the transaction.
By using sender’s private key every user in the system can verify that the transaction was indeed created by the indicated sender, as his/her private key can successfully decrypt the content of the digital signature. The exchange is authentic, since the transaction was also cryptographically processed with the recipient’s public key, the operation which is called digital enveloping. This transformation guarantees that the transaction can be accepted and processed only by the holder of the corresponding private key, which is the intended recipient.
Every transaction, and thus the transfer of ownership of the specified amount of Bitcoins, is inserted, then time-stamped, and finally displayed in one “block” of the blockchain. Public-key cryptography ensures that all computers in the network have a constantly updated and verified record of all transactions within the Bitcoin network, which prevents double-spending and fraud.

1.2 The Concept and Features of the Bitcoin System

There are many concepts and even more operational payment systems today in the world. Some are standard paper–based, some are digital and network based. What makes Bitcoin unique and distinctive, compared with all other payment systems that are in use today, are several of its core features.
The first of them is that the system uses its own currency. The reason for using its own currency is to make the system independent of financial institutions as trusted third parties. The unit of the currency is called Bitcoin. The currency is so called crypto currency, because it is generated and used based on execution of certain cryptographic algorithms and protocols. Performing specific cryptographic protocols is in the heart of operations to create new Bitcoins, to transfer them between transaction parties, and to validate the correctness of transactions.
Since appearance of Bitcoins, several new systems were introduced that use cryptography to manage its own currency, so all such currencies represent the category of crypto currencies. Later in this Report, some other digital / virtual currencies will be described that are created and managed using some other principles, so they are not called crypto currency. At the time of writing this Report, all such digital virtual currencies were called with general term tokens, sometimes also digital assets tokens. The reason is that they were created by the process called collateralization and therefore they are related to the value of some categories of real world assets which is expressed in digital tokens units.
The second interesting and important feature of the Bitcoin system is that the logical relationship between the two transaction parties is direct, peer-to–peer, i.e. there are no other parties that participate in the transaction. This is an important feature and benefit / advantage of the system that contributes to its efficiency when compared with the todays complex and expensive financial payment infrastructures and protocols. However, for distribution of transactions to their validators and later to all other members in the Bitcoin system the physical flow of each transaction is very complex and includes many parties.
It should be emphasized that performing transactions as direct, peer-to–peer transfers is one of the key features and the most significant reason for many benefits and advantages of the Bitcoin system. This approach is the key feature of the Bitcoin system as it enables security and anonymity of parties, efficiency in performing transactions, scaling of the system, and instantaneous settlement of payments. Therefore, supporting execution and validation of serious business peer–to–peer transactions is one of the core benefits of the blockchain concept, as it changes the current paradigm of Internet applications and transactions. Currently all Internet applications are organized and performed as client–server transactions. Such transactions are not efficient, do not provide sufficient privacy of participants, have dependencies on third parties and usually are vulnerable due to attacks of functional problems with large centralized application servers.
The next very important characteristic of the Bitcoin system is anonymity of users, their accounts, and transactions. This property means that the identities of the participants in the system are not known even to the partners performing a payment transaction. All other system operations – receiving payments, making payments, validating transactions, etc. are also performed anonymously. Interpreting this property correctly, the anonymity of transaction participants is so called pseudo-anonymity. Namely, in the process of validating transactions, all previous transactions of the sender are traced back to the original initial transaction. If that initial transaction was the purchase of Bitcoins at some Bitcoin Exchange, then the identity of the original owner of Bitcoins is known. Most if not all service providers in the Bitcoin system today require very strict identification of participants for the purpose of enforcing legal and regulated transactions and include certain restrictions of transaction frequency and amounts. This procedure, although understandable from the legal and regulatory point of view, has in fact in essence changed one of the core principles of the original concept of the Bitcoin system – full anonymity of users.
Better solution for fully anonymous payment transactions is so called zero–knowledge protocol, where the identity and authorization to perform Bitcoin transactions, is validated by anyone without revealing any identity information of the parties. The only problem with this approach is revealing the identity of transaction participants to law enforcement authorities in case of illegal transactions. But, such authorities have special authorization under the law and they should be enabled to get identifying information about transaction participants in the process of legal law enforcement procedures. But, all other service providers do not have such status, so if Bitcoin principles are strictly followed, they should not be able to have identifying information about system participants.
This approach and potential improvement of the Bitcoin system implies that the system needs one of the classical security services: role–based authorization. In such arrangement, there would be at least two categories of system participants: those that are authorized to maintain and access identifying information about the participants and those that are only authorized to perform transactions. In the first category are legal authorities, like police, driving license authorities, tax authorities, etc. In the context of the standard Identities Management Systems, such participants are called Identity Providers. All others are Identity Verifiers. Therefore, one of the main conclusions about true anonymity in the Bitcoin system is establishment of a sophisticated and multi-role Identities Management System, where some parties will be authorized Identity Providers and all others will be Identity Validators. Finally, referring back to the infrastructure of the Bitcoin system to perform and validate transactions – blockchain, the conclusion is that what is needed, as one of the most important extensions of the current concept of anonymity of Bitcoins participants, is an Identity Management System based itself on the use of blockchain and without Identity Providers as trusted third parties. Creation, distribution, use and validation of identities are transactions in the system, equivalent to payment transactions, so they should also be performed using blockchain protocol. Such system, that can provide reliable identities of all participants may be called Blockchain Identity Management System.
Another very important feature of the original concept of the Bitcoin system is that it is not controlled by any financial institution, by any regulatory body or by any legal financial authority when it comes to issuing Bitcoins and determining their value. This means that the currency used in the system and all transactions are exempted from any legal and financial rules and regulations. The rules controlling Bitcoin system are built in its code. This property is usually called “rule by the technical code”, as the rules of system operations, built in the code of its operational components, control and rule the operations of the system [UK, 2016], Chapter 3. This property is sometimes described as “control by the community”, i.e. the participating users.
This property implies that the value of Bitcoins is determined solely on the market – based on its supply and demand. This is quite natural approach, as the value of shares of companies are also determined on an open trading market. However, such approach implies that the value of Bitcoin, as crypto currency, is volatile related to fiat currencies. This property represent serious problem to perform payments using Bitcoin. It is well-known that volatile currencies are not suitable for payments. The practice of all the years while Bitcoins are in use has shown that its volatility represents one of the major obstacles for its main purpose – to be used as the payment system. In fact, it was announced that in 2019 the total value of Bitcoin transactions performed was about $ 11 T. However, unfortunately, only about 1.3% of those transactions were payments, all others were trading manipulations on exchanges. Based on that, it may be clearly stated that Bitcoin today is not used as the payment system, but as currency manipulation system. This is one of the main problems with the concept and current implementation and deployment of Bitcoin system and in near future may represent the main reason for its decline in popularity.

1.3 Innovative Contributions of the Bitcoin System

Besides an effective procedure to transfer an amount of crypto currency from one user (account) to another user (account), the major and indeed an essential contribution of the concept of the Bitcoin is the solution to the general problem how to establish trust between two mutually unknown and otherwise unrelated parties to such an extent and certainty that sensitive and secure transactions can be performed with full confidence over an open environment, such as Internet. In all current large scale and not only financial systems that problem is solved by using the assistance of third parties. For many (may be even all) current Internet applications and transactions those third parties are integrated and linked into a large, complex, expensive and vulnerable operational infrastructures. Examples of such infrastructures today are bankcard networks supporting global international payments, global international banking networks supporting international financial transfers, Public–Key Infrastructures (PKI), Identity Management Systems, and many others. It is a general consent that such infrastructures are expensive and, more important, vulnerable to external and internal attacks.
In addition to the complexity and vulnerabilities of such current operational supporting infrastructures, another requirement and prerequisite to use their services is that users must put the complete trust in these third parties. Accepting to trust those third–party service providers is the necessary and mandatory prerequisite to use their services.
Therefore, one of the most important contributions of the concept of Bitcoin is that it solves the issue how two parties, mutually unknown to each other in advance and otherwise completely unrelated, can perform sensitive and secure transactions, such as transfer of money – payments, but without assistance of any third party and without the need to place trust in any component of the system.
The practical benefits of solving this problem and the most important consequence of the solution for this problem – Bitcoin system, is that it provides the possibility for one Internet user to transfer not only Bitcoins, but also any other form of digital asset to or shared with another Internet user, such that the transfer is guaranteed to be safe and secure, that everyone knows that the transfer has been performed, and nobody can challenge the legitimacy of the transfer.
This feature of the Bitcoin system generated many very new, creative and innovative ideas where the concept equivalent to the Bitcoin can be used to perform secure and reliable transactions between users in an open community handling any type of digital asset ([Andreesen, 2014], [Sparkes, 2014], [UniCredit, 2016], [BitID, 2015], [PoE, 2015]). The examples of such applications and transactions range from commercial transitions, real estate transactions, energy trading, electronic voting, medical applications, and many others ([Kounelis, 2015], [Muftic, 2016]). The concept of blockchain as technology supporting validation of all such transactions is therefore called disruptive technology.
As the conclusion in this section, we may give a definition of blockchain:
Blockchain is an innovative concept, implemented as an infrastructure comprising multiple and distributed servers, mutually linked by special broadcasting and synchronization protocols, managing immutable objects with the purpose to enable and protect secure peer–to–peer transactions in a global and open environment.

1.4 Summary of Problems and Potential Solutions

In section 1.2 several problems of the Bitcoin system were mentioned and potential solutions for these problems were outlined. Recently, at the time of writing this Technical Report, several sources, mainly personal blogs and articles, appeared with very interesting opinions and statements regarding some other serious Bitcoin problems. Some of them are problems with the concept of the system, some problems of its design, and some problems of operations. In this section some of these problems are briefly summarized including suggestions for their potential solutions. The source of some problems was the article [Ein, 2018].
Problem 1: Complex Crypto Algorithms
Problem: Bitcoins is crypto currency and cryptographic algorithms used in the current version are very complex, based on the concept of proof–of–work, and require long time, special hardware and a lots of energy to perform
Potential Solution: Potential solution fro this problem is to use cryptographic algorithms that are simpler and therefore more efficient to execute and need less energy
Problems with Potential Solution: Lowering the complexity of crypto algorithms introduces vulnerability to hackers. Therefore, what is needed are strong algorithms and simple to perform for regular users and complex to break by hackers
Problem 2: Indirect Transactions, not Peer–to–Peer
Problem: Contrary to the concept claimed, in todays implementation Bitcoin payment transactions are not performed as direct, peer–to–peer transactions. They are performed indirectly, submitted to the Bitcoin network, and recipients receive them indirectly, by downloading validated transactions from the ledger
Potential Solution: Transactions should be performed directly, by transferring them directly between two users
Problems with Potential Solution: The problem with the potential solution is validation of transaction for proof of possession of Bitcoins by the sender and for prevention of double-spending. Therefore, what is needed is the protocol to validate peer–to–peer transactions.
Problem 3: Anonymity of Users not provided
Problem: Contrary to the concept claimed, in todays deployments of additional system components, mainly exchanges, users are not anonymous
Potential Solution: Blockchain–based Distributed Identity Management System with Role-based Authorizations
Problems with Potential Solution: The problem with potential solution is that it depends on trusted third parties with authorized roles. Therefore, what is needed is blockchain-based Identity Management System using hybrid (permissioned and unpermissioned) blockchain
Problem 4: Volatile Value, not suitable for Payments
Problem: Contrary to the concept claimed that Bitcoin is payment system, volatile value of the currency makes it inconvenient for payments
Potential Solution: Crypto currency with stable value
Problems with Potential Solution: The problem with the potential solution is that the value of Bitcoins is determined on the secondary market, during its trading (cash-in / cash-out). Therefore, what is needed is crypto currency that does not have volatile value
The remaining problems in this section are quoted from [Ein, 2018]:
Problem 5: Negative Environmental Impact
Problem: Mining algorithms and operational facilities (“mining farms”) consume too much electrical energy, based on the “proof-of-work” protocol
Potential Solution: Using mining algorithms that consume less energy, either as simpler / lighter crypto algorithms or using alternative crypto protocols to protect transactions integrity (“proof-of-stake”)
Problems with Potential Solution: The problem with the potential solution is that simpler / lighter algorithms open vulnerabilities to hackers while alternative crypto protocols are not backward compatible with the current system
Problem 6: Slow Performance (Delays) / Low Throughput
Problem: Due to blocking and the designed time for protection of transactions (10 minutes) Bitcoin system has very slow performance – transactions are validated in about an hour and transaction processing throughput is about 7 transactions per second
Potential Solution: Using transaction validation algorithms and protocols that do not need blocking of transactions, but transactions should be validated individually
Problems with Potential Solution: There are no serious problems with the proposed potential solution
Problem 7: Limited Number of Bitcoins
Problem: Due hardware and other types of failures, the number of available Bitcoins in the system is constantly reducing
Potential Solution: Potential solution could be to use smaller portions of Bitcoin (“Satoshi”) or introduce hard-fork by splitting the amount of available Bitcoins
Problems with Potential Solution: The problems with the first solution that it is not user-friendly and the problem with the second solution is backwards compatibility.
Problem 8: Real Value of Bitcoins
Problem: The value of Bitcoins is purely psychological and reflects only pure market speculations
Potential Solution: Potential solution could be to peg the value of Bitcoin to local fiat currencies in countries of deployments
Problems with Potential Solution: The problems with the potential solution is that such Bitcoins would be a new class of Bitcoins, not traded on exchanges and not volatile
At the end of this section, it is very interesting to quote two opinions about the future of Bitcoin and blockchain:
[Ein, 2018]: “It seems that Bitcoin will likely cease to have meaningful value*, defeating the whole point and philosophy imagined by Satoshi Nakamoto, the alleged inventor of Bitcoin. Its current value appears to be purely psychological, and the hype seems to be driven by irrational exuberance, greed and speculation. Modern human history has seen many* bubbles*, including the dot-com bubble, the housing bubble and even the tulip bubble. However, when these bubbles exploded, many excellent dot-com companies survived, most houses regained their value and tulips still have meaning and carry value in our lives today. But what will happen when the Bitcoin bubble bursts? What* utility or residual value will Bitcoin have to consumers and businesses? Most likely none*. And this is the real problem with Bitcoin and crypto currencies.*
Bitcoin will likely go down in history as a great technological invention that popularized blockchain yet failed due to its design limitations*. Just like the industrial revolution was fueled by the combustion engine, Nakamoto’s most valuable contribution is the* blockchain polymorphic engine that will further accelerate innovation in the post-information age and immensely affect our lives”.
This quote makes two very important and far–reaching predictions:
(1) Bitcoin, as the payment system will disappear (“. . . will go down in history”), and
(2) The most valuable contribution of the Bitcoin system is blockchain
This article was written in 2018. It is very interesting to notice that at the time of writing this Technical Report, (1) Bitcoin was still “alive” and (2) the concept and deployments of blockchain were in serious trouble.
Based on the principle of positive and creative approach, in the rest of this Technical Report, besides description of all technical details of the Bitcoin system, some potential solutions for its improvement will also be discussed.
However, contrary to the predicted status of Bitcoin, it seems that the predicted status of blockchain, in 2020 was still facing serious problems.
[Barber, 2019]: What's Blockchain Actually Good for, Anyway? For Now, Not Much
“Not long ago, blockchain technology was touted as a way to track tuna, bypass banks, and preserve property records. Reality has proved a much tougher challenge”.

[Lucanus, 2020]: Has Blockchain Failed Before It Even Really Began?

“Just as everyone was getting really excited about its potential, it appears blockchain is dead. For a technology that was supposed to transform and solve seemingly every problem in the world, the enthusiasm is fading pretty quickly”.
At the time of writing this Technical Report, there were many new blockchain – concepts, design and even several deployed and operational instances. Some of them are even very popular, but only among enthusiastic developers. The overall trends with real life deployments, and more and more comments about the capabilities and features of blockchains are appearing with negative connotation. Therefore, seems that even for blockchain some innovative concepts and approaches are needed. They are beyond the scope of this Technical Report and will be addressed in some of our follow-up reports.
