Bitcoins stuck with Blockchain.info "Shared Coin" feature!
Hi, I've attempted to send 2.2714 BTC from my Blockchain.info wallet using the "Shared Coin" feature to my other Bread wallet. The transaction never went through and so I clicked "Recover Intermediate Addresses" with no success. My coins are currently in limbo with Blockchain.info as they are marked as a "Double Spend". The transaction hash for the "Shared Coin" send is https://blockchain.info/tx/0a26e7463319eea3e2729f6296b917abcad8a4e06c3982038e719a7bbbf0ab1e. Anyone know how to get my coins back? I've contacted support and they told me to click "Recover Intermediate Addresses" but as I said before, no success. Please help!
Long time lurker, first time poster. Used blockchain's shared coin feature 2 days ago and my coins have yet to appear Transaction I contacted support but they have been little to no help. 24 hours ago they said "the issue should be fixed". Its been 48 hours and nothing has happened. I have used shared-coin before and it took 5 minutes so I sent my coins with confidence. I have followed the coins through 20+ wallets, they don't change and just keep jumping from wallet to wallet. I have tried blockchains unstuck feature, my browser eventually logs out of the wallet because it timesout for so long, I've also sat there for an hour making sure it doesnt timeout and it just never "unstucks". I'm slowly losing confidence in bitcoin and all I want to do is switch to fiat now. Anyone know what to do in a situation like this? As of this post this is the last wallet they appear to be in.

We’re looking to make someone a millionaire. Could it be you? Quarantine may have placed some things at a halt, but we’re still operating as usual, so comment to enter! [Drawing Thread #54]
Depending on who you are, finals are either happening now or you’re done with them. With that being said, we’re still ending our year strong!
Introduction: Welcome to anyone and everyone coming from /popular. Quarantine has been making this subreddit more popular by the day, so thank you to everyone for supporting this. For those who aren't familiar:
Every month, we ask for comments for entry, and we pick one who represents our winner.
This process is completely random and verifiable, using the Bitcoin blockchain as a sophisticated die.
Following this, people then donate to the winner using a variety of mediums, and the winner would go on to be a "millionaire" (arguably, our definition of that term is pretty loose).
Also, I want to clarify on the situation with comments: you need to make only one top-level comment. You can reply as many times as you like. However! If you haven’t made a comment DIRECTLY to this post, you will not be counted. I’ve attached a helpful graphic visually clarifying the difference between a top-level comment and a reply right here: https://imgur.com/Si1VLX4 So once again, thank you for your support. The post lasts for 24 hours before getting locked, so make sure you place your comment before 7 PM ET. In addition, I will make a [Part 2] if we reach the limit, and changing some past precedent, I will extend comment collection by a full day. Let's make a millionaire! In Case You Missed It:
Our last winner, Ultima98, is currently accepting donations! Things have gone a bit rough for him, but that hasn’t stopped him from persevering, as he describes in his post. Donations will go to himself, to his local dog shelter, and among other recipients. If you would like to donate, click on the link here!
REQUIRED: Leave only one (1) top level comment in reply to this thread! (Replying to other comments will not qualify. You must be thirty days old or older to comment.)
A random user who commented will be chosen, and everyone donates a dollar to make a millionaire.
April 15 at 7:00 PM ET (epoch timestamp: 1586991600) is the cutoff for accounts. If you have created your account after this point, you are not eligible to enter and your submission will be disqualified automatically.
May 17 at 12:00 PM ET (epoch timestamp: 1589731200) will begin the process of selecting the winner. At this time, the [Draw] post will be online and start the process of waiting for the blockchain, in order to select the winner randomly and verifiably.
Changing how duplicates are handled: Starting this month, I’ll be changing how duplicates are handled. The TL;DR version is this: make absolute certain that you only left one top-level comment! Prior to this, I have set the comments to “FirstOnly”, meaning that if you have accidentally made more than one comment, you will be forgiven, and your first comment will count. This will not be the case anymore. Make sure that you checked your account and haven’t left any more comments than you should. From now on, if you have left more than one top-level comment on this post, your entry will be automatically removed! Other than that, if you do accidentally leave one and forget to remove it, make sure you enter next month!
May 17 at 12 PM ET (16 UTC), we will be picking our winner, and you won’t want to miss it. The post will be labeled [Draw], and one comment will be selected out of the many made here to make a winner! Remember, this is about generosity, making an impact, and uniting to make someone's life better. It takes three minutes to donate a bit to the winner, whether you're well off and want to donate a couple bucks, or going through tough times and can only donate a few coins. Every cent makes cents, and counts! If a lone $1 can get you an affordable utensil, then imagine the possibilities with $1,000,000. You can get a backpack, a farewell worth remembering, and pay for those pesky classes! A million dollars can make someone’s stay away from school. Spread the word: have your friends and family comment, post the link to your friendly-neighborhood social media network, and share it to anyone interested.
Let’s educate a millionaire!
All rise for this class. Take a stand, pencil in hand. How we’ve come so far.
You may be in quarantine, but that doesn’t mean we aren’t! For those who don’t know, every month this subreddit makes a millionaire out of one comment, and donates. With danger out and about, take some time and comment to enter! [Drawing Thread #52]
I thought this year would be a lot more normal.

Mini Survey: NOTE: A Google account is required to respond to hinder tampering, but you are not obligated to answer. So I’ve been thinking about this for a while: people are not having pleasant experiences with PayPal. If the account isn’t blocked, then there are issues with fees, fear of the seizure of funds, and the risk of revealing personally identifiable information. However, it is the largest platform used by /MillionaireMakers, and is the provider of most donations on this subreddit. This survey is purely to see how people feel about this. Unless if the winner chooses to not accept PayPal, we will continue to offer this service for tonight’s thread. My questions are: 1) How would you feel about a ban on the PayPal service here on /MillionaireMakers? 2) Would removing PayPal as a service affect your ability to donate? 3) Should /MillionaireMakers remove PayPal? I will periodically post results here. If you are interested in responding, please answer here, answers will not be accepted at the time the [Draw] is posted: https://docs.google.com/forms/d/e/1FAIpQLSffkP3SKdTi9lLPbtO8taG4_-cdctYlAf8SvohvzoJvTOYdhw/viewform?usp=sf_link Drawing Process Mini-Update: This is as short as they come, leroy627 has made a commit to the repository that adds backwards-compatibility up to Python 3.5. Procedure will be run with the following conditions: the first comment of duplicates are kept for the month of March, and any ineligible comments will be removed.

Dear Community, I am a tech professional with "good" programming knowledge. I believe I have sound logic and good understanding of data structures and functions. I have security programming background as well. With the constant noise on lack of development for LTC, it is high time we try to build parallel use cases for LTC much like BTC.. I am ready to spend my weekends and post working hours of my job to spend my time energy & effort in developing something so cool. I don't know where to begin though. My initial thought process is to clone the litecoin repo and start understanding the Blockchain code so that I may contribute further developments and gain a foundational understanding of it. Any resources or guidance on this will help. I am sure it's a big learning curve but it's one I'm ready to take on. I am also thinking to noting my progress & learnings along the way for as anyone who wants to start from basics and learn their way up. Happy to know your thoughts and comments. . . Update (9 July 2020) : So I've been scouring the internet , available documentation and shared links. And I am struggling.. So far I've managed some small wins. I've successfully cloned the litecoin repository in a private repo and managed to learn a little more about litecoin from a codebase standpoint. I found an article that gives an overall understanding of codebase (I believe maybe v0.17). Also , I've come to the conclusion looking at the repo that it mainly in c++ which is not something I've coded in for a while. I've also realized that LTC code in v0.18 is cognitively difficult to grasp and my task has become a tad harder. So I'm planning to focus my efforts on v0.8 (original code) because of two reasons - strength my foundations and leverage more accessible documentation for bitcoin code to draw any parallels. I will keep you guys posted on the updates. Link: https://medium.com/@philippsandnelitecoin-satisfying-codebase-with-room-for-improvements-4af4d5f21cda#:~:text=The%20Litecoin%20codebase%20shows%20a,category%20focuses%20on%20code%20issues . . Update (19 July 2020) - After doing my research and reading literally every opiniated article & knowledge base , I've come to the conclusion that spending energy on understanding the LTC codebase may not be serving a really significant purpose. Instead due to the similarities with BTC (literally silver to gold) , I'm currently going through a book called ' Programming Bitcoin by Jimmy Song".. I've gone through the contents and it seems highly relevant to understand to build apps on top of LTC and give way to use cases like Wrapped LTC on contact networks like ETH , EOS and TRX.. (wink wink).. I am assuming that this knowledge is transferable to LTC programming. Also there is a lot of hype on the op code CTV which is apparently paving way to mainstream contract building on value chains.. Will let you know as I progress. I've also been setting up the Mustard Wallet for LTC coin join and also reading up on fungibility concepts like Coin Shuffle and MimbleWimble with the upcoming upgrade. . .
Decentr ($DEC) - foundational cross-chain and cross-platform DeFi protocol
Decentr is a protocol designed to make blockchain/DLT mainstream by allowing DeFi applications built on various blockchains to “talk to each other”. Decentr is a 100% secure and decentralised Web 3.0 protocol where users can apply PDV (personal data value) to increase APR on $DEC that users loan out as part of of our DeFi dLoan features, as well as it being applied at PoS when paying for stuff online. Decentr is also building a BAT competitor browser and Chrome/Firefox extension that acts as a gateway to 100% decentralised Web 3.0
Allows DeFi Dapps to access all Decentr’s dFintech features, including dLoan, dPay. Key innovation is that the protocols is based on a user’s ability to leverage the value of their data as exchangeable “currency”.
Decentr is building foundational chain-agnostic protocols that will support “true” 100% DeFi Dapps, a 100% secure and decentralised, user-centric alt economy. DeFi dApps inter-connected by Decentr can talk to each other and share PDV (personal data value) of their users. PDV is best described as a personalized “exchange rate” (in a sense social reputation where more effort leads to more rewards and NOT more capital to more rewards. ) between currencies that users apply at point-of-sale to make the cost of goods and services cheaper online. PDV is applied to the APR users earn on $DEC (native token) that they hold that they loan out as part of the investing pool. PDV will also allow uncollateralized loans on their dLoan platform, and also on platforms like Aave and Compound.
Decentr will implement ZKsync to get super cheap and super fast transactions across the ETH network. It is also working with HoloChain and Tomochain to allow connect their DeFi ecosystem to the Ethereum DeFi ecosystem. Decentr has DEEP TIES and a PARTNERSHIP with Holochain: https://medium.com/@DecentrNet/decentr-holochain-ama-29d662caed03
Decentr is also building a browser and Chrome/Firefox extension - a gateway that “transitions” Web 2.0 into a 100% decentralised Web 3.0 via their suite of decentralised dFintech and dCommunications features. The browser adds a 100% decentralised “user layer” to current blockchain protocols so that applications built on blockchain can actually “talk to each other”. The browser uses encryption all the time and the power of blockchain to keep private keys safe. Browser will offer a more robust and innovative type of blockchain storage and caching that is much faster than VPN or TOR. It will allow surfing .onion addresses as well as the regular ones. >>BAT browser 400m marketcap, DEC marketcap 4m<<
Decentr is researching a hardware application, powered by Decentr software, that would greatly enhance current IoT networks. It’s called a “Smart Chip Node” (SCN) and will adhere to 4G LTE standards (with in-built 5G capability), which means connectivity between devices will match or exceed current speed and connectivity, dramatically improving stability and coverage of standalone devices, such as a laptop or tablet, as well as IoT devices, such as home routers and modems.
Decentr uses Coinbase API to optimise integrated implementation of the user layer and Blockchain as a Service (BaaS) to allow users to leverage cloud-based solutions to build, host and use their own blockchain apps. Tierion’s technological infrastructure, the Chainpoint Proof protocol, will come into play whenever a user adds something in Tierion’s data store. Hyperledger Fabric and R3 Corda private blockchains are used as an immutable transaction database for data transfers, including the following tech: R3 Corda, Hyperledger Fabric, Ansible, Bitbucket Pipelines, AWS, Node.JS, GoLang, Kotlin and CouchDB.
Implements a system of layered security protocols based on a radically-new software architecture that combines Elliptic Curve Cryptography (ECC)4 and Sobol sequencing with a n-dimensional chain as part of AI-enhanced, platform-wide community consensus mechanism — a mechanism that assigns mutually agreed value to data and user security protocol upgrades (further encouraging enhanced data integrity) by deploying a Delegated Proof of Stake (DPoS) protocol.
Bank of England has reached out to Decenr to discuss the potential of a UK CBDC upon hearing about the potential of their tech. Decentr is consistent with their own R&D into a "dGBP" and they requested a top-level document for review >> Decentr created this proposal: https://decentr.net/files/Decentr_Consultancy_Doc_UK_CBDC.pdf
A fee is charged for every transaction using dPay whereby an exchange takes place between money (fiat and digital) and data, and vice versa, either as part of DeFi features or via a dApp built on Decentr. They are launching pilot programmes in the following industries:
Banking/PSP Industry: On Product launch, due to Decentr’s powerful PSP connections (including the worlds #2 PSP by volume), a medium-scale pilot program will be launched, which will seed the network with 150,000 PSP customers in primarily the Spanish/LAC markets, generating revenue from day one.
“Bricks and Mortar” Supermarket/Grocery Industry: Decentr aims to ensure the long-term competitiveness of “bricks and mortar” supermarkets against online-only grocery retailers, such as Amazon, by a) building secure tech that allows supermarkets to digitise every aspect of their supply chains and operational functions, while b) allowing supermarkets to leverage this incredibly valuable data as a liquid asset class. Expected revenue by Year 5: $114Mn per year.
Online Advertising Industry: Decentr’s 100% decentralised platform credits users secure data with payable value, in the form of PDV, for engaging with ads. The Brave browser was launched in 2012 and in 8 years has reached over 12 million monthly active users, accented by as many as 4.3 million daily active users.
TOKEN $DEC AND SALE
Decentr recently complete their token sale on a purchase portal powered by Dolomite where they raised $974,000 in 10 minutes for a total sale hardcap of 1.25M. The $DEC token is actively trading on multiple exchanges including Uniswap and IDEX. Listed for free on IDEX, Hotbit, Hoo, Coinw, Tidex, BKex. Listed on CoinGecko and Coinmarketcap. Listed on Delta and Blockfolio apps. ➡️ Circulating supply: 61m $DEC. ➡️ Release schedule and token distribution LINK -> NO RELEASE UNTIL 2021.

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
Technology and some more:
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
Down the rabbit hole
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here. Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017. Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand. Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”.Scilla design story part 1
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
“Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
Smart contract on a sharded environment and state sharding
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
Business & Partnerships
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
Marketing & Community
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
(if you would like to add information or see mistakes, just comment below and I will credit you) What is Cardano? Cardano is an open source and permissionless "Third Generation" blockchain project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values, and the second one is the reason why values are transferred from one account to the other.
Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm known as Ouroboros to generate new blocks and confirm transactions.
IOHK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another development team - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020. Cardano was the first project built on a peer-reviewed scientific development method, resulting in dozens of research papers produced by IOHK. Among these papers is Ouroboros Genesis, proving that a Proof of Stake protocol can be just as secure as Proof of Work - which was originally developed for Bitcoin, and refined for Ethereum. This PoS protocol considerably lowers the resources cost to maintain network while still maintaining security and network speed. Cardano as a financial infrastructure is not yet completed, With significant development to be rolled out. What were the other two generations of blockchain? Gen 1 was Bitcoin. It exists by itself and talks to nobody but Bitcoin. It is capable of peer to peer transactions without a third party in such a way that you cannot cheat the system. This was a major step forward for the E-cash concept that people have been working on for the 20 years prior. Gen 2 was Ethereum and other smart-contract platforms that allow other coins and platforms to be built on top of their infrastructure. These coins can interact with others on the platform, but cannot interact with other platforms. Meaning it is still not truly interoperable. Most Gen 2 blockchains are also using Proof of Work likes Bitcoin, which effects scaling. Also missing is a built-in method to pay for upgrades and voting mechanics for decision making. Gen 3 blockchains are a complete package designed to replace the current financial infrastructure of the world. Cardano is using Proof of Stake to ensure security and decentralisation(Shelley). Scaling through parallel computation (Hydra in Basho), Sidechains to allow the platform to interact with other platforms (Basho), and also include mechanisms for voting for project funding, changes to the protocol and improvement proposals (Voltaire). Finally smart contracts platform for new and established projects that are developer friendly (Goguen). Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano. The first is the Cardano Foundation, an objective, non-profit organisation based in Switzerland. Its core responsibilities are to nurture, grow and educate Cardano users and commercial communities, to engage with authorities on regulatory and commercial matters and to act as a blockchain and cryptocurrency standards body. The second entity is IOHK, a leading cryptocurrency research and development company, which holds the contract to develop the platform until 2020. The final business partner is Emurgo, which invests in start-ups and assists commercial ventures to build on the Cardano blockchain. www.Cardano.orgwww.emurgo.iohttps://cardanofoundation.org/en/ What is the difference between Proof of Work and Proof of stake? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half validators agree, then the ledger is updated and the transaction is now secured. Proof-of-Work (PoW) happens when a miner is elected to solve an exceptionally difficult math problem and gets credit for adding a verified block to the blockchain. Finding a solution is an arduous guessing game that takes a considerable amount of computing power to compete for the correct answer. It is like “pick a number between 1 and one trillion” and when you get it right, you get $30,000 in Bitcoin, so the more computers you have working on it, the faster you can solve it. Also the more people who are trying to solve the same block, the harder the algorithm, so it may become 1 in 20 trillion. The downside is the massive amounts of power required to run the computers that run the network, and the slow pace that blocks are solved. To “Hack” a PoW system, you need 51% of the computing power, which would allow you to deny transactions, or spend the same coin twice. At the moment there are 8 main mining operations for bitcoin, and 4 of them make up more that 51% of the mining power. PoS instead selects a coin at random that already exists, and the person who owns that coin is elected to put the work in to validate the block. This means there is no contest and no guessing game. Some computer power is required, but only a fraction of a PoW system. The complex nature of selecting a coin that exists on the correct and longest chain and is owned by someone who can complete the block, AND in such a way that it is secure AND that computer currently running AND that person also having an incentive to complete the work, has made the development of PoS very slow. However only a few years ago it wasn’t even possible. In this method, the more of the coin (ADA) you stake, the more likely you are to be selected to close a block. Cardano also allows you to delegate your stake to someone else to validate the block so they do the work, and you share in the reward for doing so. To “hack” a PoS blockchain you need to own 51% of the tokens, which is significantly harder than owning 51% of the computing power. What is ADA and how is it different to Cardano? Cardano is the name of the network infrastructure, and can be thought of like a rail network. ADA is the native token that has been developed alongside Cardano to facilitate the network operation. This helps confusion and maintains distinction, compared to Ethereum being the native token of Ethereum. Similar to bitcoin or any other token, ADA can be sent peer to peer as payment, but is also the reward for running the network, and what is taken as transaction fees. In this metaphor “Cardano” is the train tracks, that everything runs on. A stake pool would be the locomotive, facilitating transactions on the network while ADA is the coal that powers the locomotive. The train carriages are Decentralised applications (Dapps) that are also running on cardano tracks, but are not actively powering the network. What is staking Cardano is a Proof of Stake protocol, and uses already existing coins like a marker to ensure security. The protocol chooses a coin at random and the owner of that coin is elected to validate a block of transactions. Staking is the process of adding your ADA coins to a Pool that has the resources to run the network. If the pool you have chosen to "delegate" your stake to is chosen to close/validate a block, then you get a portion of the rewards. The ADA never leaves your wallet, and you can "undelegate" whenever you like. this increases stability of the network and also gives an incentive to pool operators to invest the time and hardware required to run a pool. What is a stake-pool and how does it work?Cardano.org FAQ on the issue goes into much more detail A stake pool is where the computing power of the network takes place. During ITN there was 1200 registered stake pools while 300 were creating blocks. You can manage your own stake-pool or delegate your ADA to an already registered pool. Rewards are determined by the protocol, however the pool may elect to charge fee Percentages, or flat rate fee to upkeep their pool. Can I Stake my ADA right now? The staking testnet has closed, If you participated in the Incentivised Test Net and earned rewards, instructions to check the balance are here. However if you have just purchased some or it was held on an exchange, then you will need to wait until the Shelley mainnet launch happening at the end of July 2020. Where do I stake my ADA? Daedalus Flight wallet, and Yoroi Wallet (as a chrome extension) are the current best options. Adalite and several other third-party wallets also exist. Coinbase will also allow staking as a custodial service, and many exchanges may offer “staking as a service” so you can leave your coins on the exchange and still earn rewards if you enjoy trading. I do not recommend leaving coins on an exchange unless you are actively trading. What are the staking rewards now and what can I expect on a return in the future? The Incentivised Test Net (ITN) Delivered 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic. Check https://staking.cardano.org/en/calculato for a clearer picture. what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 50 pools with a 1,00ADA pledge each will be overall less profitable than 1-2 pool with the max ADA pledge (unknown but likely around 300k). Even if the 50 pools have the same over stake delegated by other users and have a better chance of being selected to close a block, the 50 pools may receive lower rewards.. (at least that is the theory) Who is IOHK? IOHK is a for-profit software engineering company founded by CEO Charles Hoskinson and Jeremy Wood in 2015 that has taken a scientific approach to the development of blockchain. IOHK started with “first principles” and looked at questions like “what is a blockchain” and “what should a blockchain be able to do” rather than accepting the established paradigm of Bitcoin and Ethereum. IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atala, Mantis and possibly other Blockchain related programs and infrastructure. Who is Charles? Charles Hoskinson is an early adopter of cryptocurrencies, American entrepreneur and cryptocurrency specialist. Charles Co-founded Ethereum with Vitalik Buterin and 5-8 others, However he only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project. Why isn’t ADA on coinbase? Cardano and coinbase have recently connected in a big way. With IOHK turning over all their ADA to the custodial services of Coinbase. This means that Cardano and Coinbase have been working together for some time and there is a strong partnership forming. Staking and cold storage will be available and trading on Coinbase will most likely become available after the release of Shelley (although no official word yet) Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon. Cardano does have a dedicated community driven wiki https://cardanowiki.info/wiki/Home What is Atala and why do I care?* Atala is a suite of services being developed on top of the cardano blockchain by IOHK that focusses on credential certification, for things like education, work history and degrees (Atala Prism). Product counterfeiting protection through registering products on a blockchain and create taper-proof provenance. This does not only apply to Gucci handbags, but also medication, art, and anything that can be counterfeited (Atala Scan). As well as supply chain tracking to see issues and inefficiencies with greater transparency(Atala Trace). Im new, how much is a good investment? Cardano is still a speculative market and although there is amazing potential here, it is still only potential. When investing in any High risk market like Crypto, only every invest what you are willing to lose. Cardano may be testing the 10c barrier now. But in March it dumped to 1.7c. And if you suddenly need your money back during the dump then you are out of luck. Do your research before you FOMO in. Start with a small amount and send it between wallets and exchanges to understand how the system works. Store your private keys offline (or online cloud service but encrypted) with a method that is unlikely to be damaged AND have multiple copies. So in the case of a house fire or a blow to the head, or the cloud service being shutdown/destroyed, you do not lose your money.

Hey guys, my name is Tolik and I'm new to Nano. I would like to tell you a bit about myself, and then about some ideas that I would like to share with you :) I'm a content creator form Israel, and I have about 65k subscribers over my 3 channels. I'm also the first Israeli partnered on Twitch and been doing that for 8 years now. Had a lot of fun with it for the first few years, playing my favorite games and earning good money, and eventually burning out hating the game that got me all my following. Our (Israeli) community exploded on youtube, but to make the most of it you need to make mindless trendy content, playing trendy and pretty childish games. I did that for a while, but it was too hard for my mind and I ended up burning out hard stepping away for a long while. Back in 2013 I first stumbled upon the world of crypto and realized the potential of the blockchain and the implementation of that technology in our world. Not enough to buy enough to get rich, but I never even considered that it could get to the volumes it got to now. In 2017 when it exploded, I realized I had some leftover coins from 2013-14 and cashed out a few thousand dollars, with the pain it could have been millions if I was a little more aware. Oh Well. A few years ago, I got into the world of self-development and got a new perspective on life. Doing only what I love and grooming a small but good community on youtube, not caring about trends, views, and money in my pocket. A few days ago, a colleague of mine started to promote some unknown coin to his child viewers, basically, the premise is a coin that you could mine on your phone. Immediately I had some red flags popping off my mind, especially because he promoted some shady CSGO gambling sites that I didn't even want to look into. He of course had his promotion code for registering to the gambling site, and using the mentioned crypto (downloading the app). If you can mine it on your phone, what would stop you using an expensive setup and just dominate the market? The fact that he advertised it as a get rich scheme, and the fact that it's a referral pyramid network, does not seem safe. After looking into it I did not see any promise, especially after I found so many altcoins with big communities that his crypto didn't have, information that did not add up, and a bunch of weird stuff going on. Because I started researching the crypto world (after so many years not being aware of what happened to it), youtube started suggesting me videos about it, one of them was u/SonderDev 's nanoPaint (Sorry I made SpongeBobs eye red) and started doing some research on nano and the technology. For 3 days I devoured all the info I can, reading most of the posts here on reddit, and joining on Discord and TG. I again felt that butterfly feeling in my gut, the one I felt so many years ago when I found out about bitcoin (and some other rare occasions). So much potential, and I kind of feel I am already late to the party, and yet, my mind can't stop thinking about what is possible. Now to the good stuff! Donations(tips) to streamers and content creators were always a huge part of our revenue. But we had a lot of problems with it - High fees, making small donations pretty much impossible, and the fear of someone charging you back and having you pay the fees for every donation that got charged back. I had someone give me about $2k for the span of two months with small donations, ended up charging all that money back, and having me pay $10 for each of his donations, even if they were under that amount. PayPal is pretty crazy. Also, If you consider something like Patreon (a monthly donation for a project or a creator you like for benefits) they also charge extra for their fee, and people can still charge you back, even though they will handle it, you still give them the benefits. Twitch takes a huge cut for subscribers (user pays $4.99 and I get as little as $1.70) and youtube are getting about 30% for their cut. See where I'm going with this? As proof of concept, a simple donation website/app could be made. You send the creator any amount of nano, it pops up on the screen for everyone to see. People would love the idea to impact the stream with as little money the creator allows. That would start up a conversation, people would start seeing the technology in action, how fast and feeless everything is going. Not to mention an integrated service could be made that is similar to delegate.it (allows users to do tasks for nano/fiat) in this instance, the tasks could be - follow the creator on Twitter, Instagram, like his posts and whatever else he decides, and it could be cheap, because people would be doing it to pop up on stream and help the creator, not for the actual fiat amount of the nano given. killing 3 birds with one stone. Promoting nano, allowing everybody a voice to a degree they choose, and promoting himself to his viewers. If this works, we could either go to one of the 2 biggest platforms (StreamLabs and StreamElements (who are Israeli and I know the 2 founders personally)) and they would integrate it to their already build system, or develop something to solely promote nano. We could reach out to smaller streamers that have small dedicated communities, not many donations and revenue coming in and allow them to use our system to promote their content and interact with their viewers. A few more ideas I have in mind for a project like that: For the donations (tips) • Having different donation alerts for different QR codes that you scan. Similarly to what NanoPaint accomplishes, we could have a different QR code to scan for an alert that the user chooses to show up. • Coloring the Camera frame - similarly to NanoPaint, drawing pixels on the frame of the camera of the streamer, changing it in real-time for nano. • Having text to speech for the alert • Have your donation impact the streamer in AR (putting something on his face or head). Crowd Funding • Donation goal that will make a purchase only if it gets there - setting up an X day goal to buy a new GPU for example, and having people contribute to it, and if it's reached, it automatically makes the order from amazon or wherever (having the data safe with our service), and if it's not - fully refunding the users. It could be a daily goal for pizza or whatever they choose. It will allow integration with businesses that would work with us. • Stream goals - if we get to X Nano this stream, 24 hour stream tomorrow! If we won't, get your nano back! Would encourage people to participate even if they are not sure the goal will be met, have the assurance that the full amount would be refunded if it did not get there. • Challenges - starting a bounty challenge, for example, have an Ace in CSGO (kill all 5 enemies) and get X amount of nano. If you didn't, money goes back. the crowd could vote on it having more interaction and validating if the challenge is complete. Voting • Have people engage with polls in real-time with nano, could scan their option to vote, and even get refunded if their option did not win, encouraging them to vote for their favorite option, even if it seems unlikely to win. User Battles • Having people start a challenge of a game, in an app or on the web, or perhaps even something random like gambling, and having it appear on stream for everybody to witness. Maybe even challenging the streamer for a nano incentive or someone else who watches. Chat • Having an on-screen chat that changes the colors and design of the people who donated with nano, and linked their account. more incentive to donate. Stream Sponsors • Having a rotating banner on-screen at all times, allowing users to pay nano to show their banner. As an auction or a price set from the creator. Most of these ideas occurred to me as I was writing this post, and I'm sure we could think of better ones with some effort. Some of them are already implemented on the websites that were mention above, however, having the power and speed of the nano is a game-changer IMHO. So why am I writing this post? First, just to share with you and get to know you better, maybe spark an idea or a motivation for anyone to do something good for nano. Second, money is tight now, moved back to my parents due to the pandemic, hard to find a decent job as we have more than %20 of the people in Israel looking for a job and as I mentioned before the content I make is not very profitable. I can't afford to invest money in this idea, and I lack the skills to do it myself. So maybe if it's good someone else could. If, however, someone would be inclined to help make this a reality, I would appreciate any comments, suggestions, investment of time, or money in testing this out. I have a dedicated community with thousands of people that will be aware of nano if we'll do it, years of experience in this field, and not to mention that I'm in good relations with most of the other content creators and platforms here in Israel, and some international. Discord: ToLy#2657 Feel free to DM me at any time :) Nice to meet you, and thank you for reading.
How to Explain Bitcoin: 3 Tips to Have Better Bitcoin Conversations
BTC Friends, Let’s be honest, Bitcoin is confusing. Not to you (you are on this / after all), but to the people who have no idea what it is. Trying to explain Bitcoin is even harder. I’m sure we’ve all had those long, complicated, drawn-out conversations which leave people more confused than when it started. To aid its adoption WE HAVE TO GET BETTER AT EXPLAINING WHAT BITCOIN IS. Here are a few tips that should, hopefully, help you manage a simple and easy to understand discussion about Bitcoin. Before we get to that, a few things to remember: Bitcoin is afundamentalchange from what most people believe. An explanation about Bitcoin shouldn’t be about “being right” or “winning the argument.” Instead, it should be about helping someone explore a new idea and begin to understand that there are actually different alternatives to the only “money” they’ve ever known. Bitcoin is complicated. It’s important to remember that this is as much of an emotion transformation for someone as it is a logical one. A CONFUSED MIND ALWAYS SAYS NO. If you leave a person confused or frustrated about what Bitcoin is, they are more likely to build up a resistance to it and become close-minded because “it’s just too complicated.” Adoption is a marathon, not a sprint. Don’t feel the need to word vomit all of your intense 1337 cypto-knowledge in a single conversation. Slow and steady. Like a good story-teller, keep them wanting more. Now, some tips to consider: 1. Start with ‘WHAT is Bitcoin?,’ not ‘WHY is Bitcoin?’ A fundamental mistake that people make is to try to justify WHY something exists before even explaining WHAT something is. Your explanations need to act as a building blocks of knowledge which means you have to have a very clear, very easily understood, fundamental premise: Bitcoin is…: Digital coins that exist on the internet that you can spend and save just like the paper money in your wallet. An alternative form of money than what you are given by your local government. That's it. That's Bitcoin. While I’m sure we can, and probably will, argue about what that base, fundamental definition is, it’s important to start with WHAT, not WHY. While hyperinflation, store of value, scarcity, the Federal Reserve, and how the printing of fiat devalues currency are all important, it does not answer the question of WHAT is Bitcoin. If you start with WHY, you are skipping a major building block in the mind of the listener and are on your way to creating confusion. And remember, a confused mind always says no! Here is an example. (Now, don’t go full-internet on me. I’m not degrading this person or this video THANK YOU PERSON FOR MAKING THIS VIDEO. This video is awesome! I only bring it up because it is a recent video that got some attention. It also demonstrates this point.) When asked to explain Bitcoin, here is the opening line: “The FED…is out of control with printing money…” This is a ‘WHY is Bitcoin’ response. Already, the listener is probably thinking, ‘what the heck does the FED have to do with anything? I just wanted to know what Bitcoin was…’ and you may just lose your listener right there. Furthermore, this video never actually says “Bitcoin IS…” While there is an implied comparison to gold, there is never a fundamental definition of WHAT Bitcoin is. Start with a clear, concise definition of WHAT Bitcoin is before moving on to WHY Bitcoin is. 2. Let Them Lead / Gauge Their Interest / Know When To Stop When explaining any topic to someone who doesn’t understand it, there is a very strong temptation to TELL everything you know. This is human nature. We are proud of what we know. We want to display knowledge and proficiency. We must, however, understand that it is counter-productive to the learning process. Imagine that certain math teacher going over that certain math problem. They explain it. They are enthusiastic about it. They write it on the chalkboard. Yet your eyes glaze over. It’s too much too fast. You are just waiting until the end when they finally tell you the answer. All logic and reasoning and understanding is gone. This is similar. Instead of telling them everything you know, LET THEM ASK! Allowing your listener to ASK demonstrates two things: an understanding of the last thing you said and, more importantly, interest! Ultimately, that’s what we want and need; their interest. Believe me, just like that little kid asking, ‘why, why, why…?’ They will give you every opportunity to share a little bit more, and a little bit more. For example: Bitcoiner – “Bitcoin are digital coins that exist on the internet that you can spend and save just like the paper money in your wallet.” (STOP TALKING AND LEAVE SPACE FOR THEM TO ASK!!!) Noob – “Oh…ok…well…why do we need that? What's wrong with the money I have now?” Bitcoiner – “Well, there is a risk that, over time, the money that you keep in your wallet or bank account will actually be worth less and be able to buy less stuff.” (STOP TALKING AND LEAVE SPACE FOR THEM TO ASK!!!) Noob – “Wait, what do you mean?” And we are now on our way to a discussion about these messy and intense concepts of inflation vs deflation, printing of fiat currency, fractional reserve lending, etc. And through it all, LET THEM LEAD. Now this is the tough part. If their eyes glaze over, YOU HAVE TO STOP! When the questions stop, YOU HAVE TO STOP! The last thing you want to do is ramble on once they’ve stopped listening. Instead, ASK them a question: “I’m sorry, did you not understand something I said?” “Did I answer your question?” “Is this interesting to you?” By doing this, you will give them an opportunity to ASK you another question: “…back up…what did you mean when you said ‘store of value’?” Or maybe even make a comment: “…wow…this stuff is pretty complicated…” In either case, this actually helps keep the conversation going. Just back up, explain it again, keeping in mind your base concepts and definitions, and see if you can talk them past where they got stuck. Maybe they shut you down entirely: “you know what, this is crazy, it can’t be true, let’s change the subject…” To which the ONLY correct response is, “Ok!” (we’ll get to this later). Keep in mind that letting your listener lead will allow you to carry the conversation much further than you trying to push it along on your own. 3. Know Your Role / A Little at a Time / Don’t Overcorrect So, what’s the end goal? Is it to have them whip out their phone, download an exchange, and make their first Bitcoin purchase right then and there?! No, of course not. The role of these conversations is to LEAVE THEM WANTING MORE. Your goal should be to spark interest and curiosity. If after talking with you they end up on The Google or The YouTube looking for more information, then you’ve done your part! Movies and TV condition us to want the big payoff at the end: the parade, the teary embrace, the triumphant symphony. That is not real life. Really, the best ending to a Bitcoin conversation might just be your listener making an audible, but clearly deeply contemplative, “…huh…”. You’ve done your job. You’ve got them noodling something they have never noodled before. Even once you understand Bitcoin, there is still an entirely different conversation about what the technology is, how it works, and how people interact with it. And let’s be honest, it’s complex and confusing. Exchanges, blockchain, forks, difficulty adjustments, miners, cold storage… More complicated ideas. More jargon. Make sure you throttle yourself back and explain just A LITTLE AT A TIME. It’s ok to have one conversation about the fundamentals of Bitcoin and then an entirely different conversation about blockchain technology or how people acquire BTC or the difference between storing Bitcoin on an exchange versus a cold wallet. Don’t fall into the trap of thinking you have to tackle all of this at once. While all this is happening, BE CAREFUL NOT TO OVERCORRECT. People know what they know, right? And what people know is always correct, right?? Be sensitive. If your listener makes a comment that isn’t true or is off track, don’t scold them or forcefully correct them. If your listener feels attacked or threatened, conflict will arise, and once that happens, their minds will be completely shut off. No one listens during an argument. Don’t attack. Explain. For example: Noob – “Well, the USD is backed by gold, so that will prevent it from ever devaluing!” Bitcoiner – “You know, it’s pretty interesting, a lot of people think the same thing. The truth is that while the USD was backed by gold for a long period of time, it isn’t anymore. You see, back in 1971…” Keep it simple, factual, and non-confrontational. Going back to our example from before, even if your listener shuts you down entirely, THAT’S OK! They have now experienced a Bitcoin conversation that will percolate around in their brain. And perhaps next time they hear the word Bitcoin, whether on the news or on the internet, they’ll think back to your conversation and what you shared with them. Hopefully you didn’t over-press and their memory of your conversation isn't a negative one which leaves them feeling negative about Bitcoin: “Bitcoin is stupid and people who believe in Bitcoin are arrogant and rude.” Finally, ENCOURAGE THEM TO DO THEIR OWN RESEARCH. The journey doesn’t start and end with you. You are simply a stepping stone along their path. Know that you are playing a part in their story; you are not the main character. Adoption of Bitcoin will occur over a long period of time. The conversations we have with our friends and family will create the buzz, attention, and understanding that is needed, but please be mindful that you are doing it in a helpful and productive way that leaves people wanting to know more. Oh, and step 4: Stack Sats and HODL!
PSA: How to use crypto to sell/buy PMs on r/PMsForSale
TL;DR 1: this is not an investment recommendation. This is not an endorsement of any crypto coin, token, or service. This post (which is a bit longish) describes how to use crypto as another payment mechanism. It would just add another tool to your PM trading toolbox. TL;DR 2: This is not an exhaustive review – it’s a simplified how-to. Calling me out on certain minute aspects is useless. However, if I made a mistake, or omitted something important PLEAESE correct me. TL;DR 3: I’ll describe everything in chapters, so as you go down, if you feel this is irrelevant to you, you can stop without spending too much time reading it all.
Chapter 1: Why use crypto
You control the entire transaction, end to end. You do not need a third party (Like PayPal or Google) telling you what you’re allowed to sell, and for how much. You do not need to resort to subterfuge (“use Friends & Family, and make sure to leave no notes!”).
Crypto transactions add a level of privacy (depending on how you use them).
Transactions are secure (read more about blockchain technology), and usually only involve you sharing your crypto address with your counterpart.
Transactions are irreversible – good if you’re an established seller who’s afraid of chargebacks by scammers.
Yet transactions can still be proven – they’re out there on the blockchain, available for all to see.
Most of the time, transactions are fast (depending on network traffic and amount of gas paid).
Chapter 2: Types of crypto
I’m not going to go into technicalities, and definitely not recommend anything. Let’s just split the crypto world right now into 2 types of coins: stable, and unstable.
Unstable coins (Bitcoin, Ether, Ripple etc.) can see their fiat value go up or down several times a minute. They’re volatile, and while they can be used to pay, the buyer and seller need to agree on the spot, convert fiat to the coin and start the transaction – at the end of which, the fiat value received may be higher or lower than when the transfer started. Because of that, I’ll avoid discussing them here.
Stable coins usually run on the Ethereum blockchain, and use a technology called “smart contract” to attach their value to fiat. A stable coin like USDC, DAI, USDT etc. will always be worth $1 (give or take 1% at certain times). For all intents and purposes, if I quote you a price of $250 and you send me 250 USDC – we’re done.
Chapter 3: what do I need to have to trade in stable coins?
An address – your crypto address allows you to control crypto on the blockchain. More specifically, it allows you to withdraw funds (since everyone can deposit to your address, whether you want it or not).
A crypto wallet. A wallet is NOT where you hold your coins! Your “money” is on the blockchain, assigned to your address. Your wallet allows you to mange the coins in that address. You can either use one of the free wallets out there, or have one provided to you by an exchange. I recommend MetaMask. It runs as a browser extension (Chrome, Firefox, Brave) or a mobile app. Make sure you do your due diligence before selecting a wallet, so you wont use a scammy app, that will use your pass phrase to clean up your address!
Some Ether (usually 0.05-0.1 ether is enough for several transactions) – every transfer on the blockchain has a fee, representing compensation for the computer work done to transfer funds from address to address. This fee, known as “gas” can go from fractions of a cent to several dollars – depending on the blockchain traffic at the time. You can control the amount of gas, and price of gas for your transactions, but generally speaking: the less you pay, the slower the transfer. Gas is paid in Ether only, so you need some in your wallet (see below on how to get it).
If you want to sell using crypto – you’re done!
If you want to buy using Crypto, you’ll need to convert some fiat to stable coins – see next chapter.
Chapter 4: Quickest way to get stable coins
The easiest way to start (in the US – your miles/kilometres may vary elsewhere) is to open a Coinbase account. (Disclaimer: you can choose any other exchange. I’m not compensated by Coinbase, I have no stake in Coinbase, I don’t work there, or know anyone who does. There’s a reason I mention them: they make this simple.) While Coinbase is the fastest and easiest way to go for noobs, there are some caveats:
Coinbase is a registered financial company. They require full KYC (i.e. photo of your driver’s license). Everything you do gets reported to the IRS, authorities, etc. But then, your bank does the same.
Coinbase doesn’t care where the funds come and go – unless law enforcement, IRS, SEC etc tell them to care. If you’re privacy-oriented, an exchange is not for you, go to the next chapter.
Let’s look at the steps of using Coinbase, and how much they’ll cost you:
Open Coinbase account (free)
Go through KYC needed to connect a bank account to your Coinbase account (free)
Transfer fiat to your account (free if bank transfer, otherwise credit/debit card fee applies)
Convert fiat to the stable coin USDC (FREE! Since Coinbase “owns” USDC, they don’t charge anything to convert back and forth between USD and USDC. And it’s always 1-1 conversion.)
Transfer USDC to an external wallet (yours, or a sellers) (FREE! Again, another perk – Coinbase pays your transfer gas fee).
If you’re content with using Coinbase as your wallet, you are done!
a. When you want to buy, you ask the seller for his address, and transfer USDC to him (free). b. When you want to sell, you give the user your Coinbase USDC address and he sends there (free again). c. Make sure you send the right address – there are no backsies in crypto!!!
Using your own wallet:
Install MetaMask. Follow instructions to create your address. Make sure you keep the pass phrase safe (NOT ON YOUR COMPUTER).
Go through steps 1-5 to convert some fiat to USDC for free.
Buy some ether – Currently Ether spot is about $230, meaning it’ll cost you about $10-20 to get some Ether + whatever fee Coinbase has on trading.
Send the USDC to your new address.
Send the Ether to your new address.
You are now good to send and receive payments!
When you receive USDC from a buyer, you can either keep them in your wallet for further use, or send to Coinbase, convert to fiat and send to your bank account. Always remember: on Coinbase 1 USDC == $1.
Chapter 5: Doing it on your own – for advanced users only
If you don’t like sharing all your info with Coinbase, you can definitely just install your own wallet (MetaMask is still the best option, IMHO, but there are many more), and fund it personally. The biggest challenge you’ll face is: how do I convert fiat to crypto? Here are some options:
The easiest: get someone to sell you some. Someone who already went through the whole process, and will agree to give you some crypto. Once you have crypto, you can easily convert it to any other crypto, without using any exchange, using crypto swap apps.
The more expansive: use a service like Changelly (and there are others – again: I have no stake) to “buy” crypto. Take into account that they have fees. There are also services (like LocalBitcoins) that will allow you to buy directly from other people, for lower fees.
You can use a different exchange, perhaps even one in a different country. Take into account that you’ll need to get actual money there, so at one point, someone will know something about you.
As said, once you have ANY crypto in your wallet, it’s easy to convert it to stable coins, Ether, or everything else you need.
I tried covering the basics of using crypto for payment. I did my best to avoid techy aspects and jargon. Crypto is here to stay. Next (and current) generations will use it, like we’re using credit cards and PayPal. It will have no “magic” or “hoax” attached to it. It’s not “good” or “bad” – it’s just another way to convey value. I was taught all this by someone. I’m sharing this with you now, in the hope you’ll share it with other people. That’s how knowledge grows. If anyone wants any clarification, or expansion on any item, feel free to comment below, or reach out to me.
Shared Coin is a method of making transactions which requires less trust in the service. Shared Coin is based on the CoinJoin concept which acts as a meeting point for multiple people to join together in a single transaction. Having multiple people in a transaction improves privacy by making transactions more difficult to analyse. I can see a recent blockchain.info “confirmed” transaction in a shared wallet, but I do not have a balance? 0 Moved Bitcoin-Qt wallet to blockchain - can see my funds but can't send them? Buying crypto like Bitcoin and Ether is as easy as verifying your identity, adding a payment and clicking "Buy". Sign up for our Wallet today. Create Wallet. Trade Crypto at the Exchange. Integrated with the Blockchain Wallet, our Exchange is a one-stop shop where you can deposit funds and place trades seamlessly in minutes. Get Started. Dive Shared Coin doesn't use or force like size inputs, it makes a list of random sized outputs and makes transactions on your behalf from blockchain.info's own wallet. What you end up with in the end is a chain of transactions in which every input is unspent except for the one owned by the initiator of the coinjoin, which is spent all the way until Bitcoin users in need of serious transaction privacy should avoid popular services like Blockchain’s SharedCoin and other CoinJoin implementations, according to a well-known security expert.
