Its been almost ten years since Satoshi Nakamoto first introduced Blockchain technology to the world in his 2008 Bitcoin Whitepaper. Since that time, these revolutionary networks have gained popularity in both the corporate and governmental sectors. This growth is easily explained when you consider that blockchain technology provides the world with some unique advantages that were previously unimaginable. Consequently, today, you can find blockchain technology in nearly every sector of the global economy.
What is Blockchain Technology?A blockchain is a network of computers that share a distributed ledger across all network participants (nodes). This strategy is far different than say, fiat currencies that originate from a centralized authority figure. Importantly, this ledger keeps an unbroken chain of transactions since the birth of the network. This “chain” of transactions grows larger as new “blocks” of transactions are approved and added to it.
In order to approve new transactions, each node works together with others to validate new blocks. Additionally, the nodes also validate the current state of the entire blockchain. In order for a new block of transactions to be added to the blockchain, they must receive approval from 51% of the network’s nodes. Nodes are also referred to as miners. In this manner, blockchain networks are decentralized networks that provide unmatched security to the world of digital assets.
Security via DecentralizationDecentralization is an important aspect of blockchain technology because it makes these revolutionary ledgers immutable and unalterable. In fact, since there is no centralized attack vector, hacking a blockchain is nearly impossible. The larger the blockchain network, the more secure the data on it remains.
For example, let’s look at the world’s largest blockchain, Bitcoin. Currently, the Bitcoin blockchain has over 10,000 active nodes located across the globe. This distribution means that in order for an attacker to alter even just one tiny piece of information on the blockchain, they would need to successfully hack 5,000+ computers at once.
While this task may not be impossible for the quantum computers of the future, it’s so unprofitable that it makes no sense to even attempt such a monumental task. Additionally, on top of successfully hacking 5000+ computers at once, an attacker would also need a supercomputer to recalculate the new blockchain transactions in time to introduce them into the network. It would literally be more affordable to create a new cryptocurrency from scratch.
Consensus MechanismsOne of the reasons why blockchain networks are so secure is the integration of consensus mechanisms. Consensus mechanisms are cryptographic protocols that leverage the participants of a blockchain network in securing its data. In the case of Bitcoin, the Proof-of-Work (PoW) consensus mechanism is used.
Proof-of-Work (PoW)The Proof-of-Work consensus mechanism was revolutionary to the world of cryptography when it was first introduced years prior by Adam Back in his Hashcash whitepaper. In the concept, Back describes the integration of a mathematical equation to the network’s security protocols. In this way, every computer can show “proof” of their work securing the network.
Miner RewardsIt’s important to understand that nodes receive a reward for their mining efforts. These rewards adjust automatically depending on the network’s difficulty and value. In the case of Bitcoin, miners originally received 50 Bitcoin for their efforts. Today, this seems like fortune, but back in 2009, Bitcoin was only worth pennies. As the value of the token rises and the network goes, the mining rewards shrink. Today, Bitcoin miners receive 6.5 BTC if they add the next block to the chain.
SHA-256Notably, every node validates and secures the blockchain, but only one gets to add the next block of transactions to the network. To determine who the next miner is that gets to add this block, every computer competes in a mathematical race to figure out the PoW equation. In the case of Bitcoin, the equation is known as SHA-256. Importantly, the first SHA algorithm dates back to Hashcash. This early version of the equation was known as SHA-1.
Notably, the SHA-256 equation is so difficult that it’s easier and more efficient for your computer to just make random guesses rather than attempting to figure out the equation directly. The answer to the equation must begin with a predetermined amount of 0s. In the Bitcoin blockchain, the equation’s answer must start with four zeros. However, if the network’s congestion rises, so does the difficulty of these equations. This difficulty adjusts by the addition of another zero at the beginning of the required SHA-256 answer.
Similarly to traditional commodities such as gold, there are costs that are associated with the creation and introduction of these digital assets into the market. These random guesses utilize intense computational power. This power equates to real-world costs such as electricity bills. Studies have shown that securing the Bitcoin network can use more electricity than required by entire countries. Luckily, over 80% of Bitcoin’s power consumption comes from renewable sources such as solar or hydroelectric. This cost of mining also adds measurable value to each Bitcoin.
MinersAs Bitcoin began to gain in profitability, its network’s computing power expanded significantly. In the beginning, nodes, also known as miners, could mine for Bitcoin using nothing more than your home PC. Eventually, miners realized that graphic cards were far better at the repetitive guessing required to figure out the SHA-256 algorithm. This led to a computational race in the market.
ASICEventually, large blockchain firms such as Bitmain introduced Application Specific Integrated Circuit (ASIC) miners into the equation. These purpose-built miners were thousands of times more efficient at guessing the SHA-256 algorithm than the GPUs and CPUs before them. Consequently, their introduction created a scenario in which the average miner now needed to invest thousands in mining equipment to stay relevant.
Mining PoolsLuckily, some creative minds in the field began to think of ways to level the playing field out again. They developed “mining pools.” A mining pool is a network of miners that all share computational power for the common goal of mining blockchain transactions. Importantly, mining pool participants receive a percentage of the reward based on their contributions to the network’s overall hash (computational power).
Importantly, over the last three years, there has been a push to move away from power-hungry consensus mechanisms such as PoW. This desire to secure blockchains in a more efficient manner has led to the development of some truly unique consensus mechanisms in the sector.
Proof-of-Stake (PoS)The Proof-of-Stake mechanism does away with the difficult mathematical algorithms and instead utilizes a more psychological approach to securing the network. In a PoS blockchain, users don’t need to compete mathematically to add the next block to the blockchain. Instead, PoS users “stake” their coins via network wallets to secure the network. The way staking works is simple.
Keeping a certain amount of coins in your wallet allows you to participate in transaction validations. The more coins you stake, the more likely the chances are you get to add the next block of transactions to the network. In most PoS systems, a miner from those with the most tokens staked at the time receives the chance to add the blocks.
The advantages of a PoS consensus mechanism are immediately evident. For one, you don’t need to pour tons of resources into your network to keep it safe. Additionally, since nodes are chosen based on their amount of staked coins, there is never a scenario in which a node gains anything from validating incorrect transactions. Basically, a hacker would have to fully invest in the cryptocurrency prior to attacking the network. In this way, PoS systems create a huge deterrent to attackers.
The Future of Blockchain TechnologyBlockchain technology has come a long way from its early days as a means to secure cryptocurrency networks. Today, blockchain technology has numerous uses across every type of industry imaginable. Specifically, blockchain programs have impacted the logistical, financial, and data security sectors in a major way.
Blockchain Technology LogisticsBlockchain logistical systems are more efficient and cost-effective to operate than traditional paper-based models. In fact, the immutable and unalterable nature of blockchain tech makes it ideally suited to logistical tasks. Soon, you may be able to ascertain much more information regarding the creation and delivery of your products thanks to these new-age systems emerging.
FundraisingBlockchain technology has also altered the way in which businesses raise funds. In a traditional corporate crowdfunding strategy such as an IPO, companies must balance between cost-effectiveness and participation. The inability to process smaller transactions meant that for the longest time, companies had to turn away potential investors. Nowadays, blockchain technology enables businesses to easily automate these procedures via smart contracts.
Smart ContractsSmart Contracts feature preprogrammed protocols that execute when they receive a certain amount of cryptocurrency sent to their address. These contracts live on the blockchain and enable remarkable functionality. For example, in the case of fundraising, a smart contract can automate processes such as the approval of investors and the distribution of funds.
Blockchain Technology TodayYou can expect to see further expansion of the blockchain sector in the coming months as more governments and institutions explore its benefits. For now, the blockchain revolution is well underway.
We are back!submitted by mineshop to gpumining [link] [comments]
For the last 2 years there was not much to shill in mining mining was on the life support. And the profits constantly got decreasing. Start of 2020 Bitcoin and Altcoins are showing great performance in price action. This price action has also increased mining profits in some coins for more then 100% since december 2019. It might be to early to say that “we are back” , as crypto can be so unpredictable. But there is a lot of signs that we have now oversold a lot and value of crypto market is increasing steadily. We might see this pattern continue for good bit of times as BTC halving is coming up in 3 month. Let’s get in straight in. I will choose 3 hardware devices which in my opinion would be the best choice and we will see how profitable they are.
If you are new to mining and you want to know which devices to choose, choose from top market cap coins latest equipment. This will be your safest bet, as the mining profits are much more stable on bigger cap coins then on smaller cap coins. If you are small miner and don’t have large electric bills, you can choose smaller cap coins. They might go up in price lot faster then bigger cap coins in bull market, but be aware they they might dump lot faster. It is high risk high reward type of mining.
If you are really serious about mining, you need to look at cheapest power source possible which would be in 0.05c a kw/h range. It is not 2017 and mining from home wont be profitable at 0.30c a kw/h. Industrial power is possible to achieve 0.05 in many places in the world. If it is not possible in your country , look for the country where it is possible. So all profit calculations done for 0.05c a kw/h
Top mining profitability websites :
The top and 3 most profitable Crypto currencies to mine in February 2020 , for some people miner pick could be different. The prices changes if you are buying new/used , depending in which part of the world are you. This is my recommended , brand new purchase in Europe.
These would be my to pick miners for start of 2020. There is big risks in any on these miners as no high reward investment is guaranteed anywhere. I’ll have more detailed explanation of the risks of each of these miners in my next post.
Any miner suggestion, what would be your best choice and why?

What is the hottest blockchain project in 2020?
Besides GFS, GFS is still GFS in my mind! GFS currency - the only token of Forbes cross chain blockchain!
Forbes is the latest generation of blockchain, which can be said to be a new blockchain mode, or it is not a pure blockchain project. As we all know, in the era of blockchain 1.0, the bitcoin of Nakamoto brings decentralized distributed bookkeeping book, which enables human beings to have just assets for the first time; in the era of 2.0, the Ethereum smart contract created by V God makes the blockchain have divergent applications; in the era of 3.0, innovation public chains such as EOS make the application of blockchain easier to land. It will open Forbes in the era of blockchain 4.0 and create a distributed financial era of "ten thousand chain interconnection". My feeling is that Forbes is going to overthrow the traditional Internet and the classic blockchain, and reshape a financial world built directly on the blockchain.
The most classic sentence on the Internet is: change your life, but it has nothing to do with you.
In this way, Forbes uses the philosophy of blockchain and further technology to redo blockchain and bring blockchain to a new dimension. Today's bitcoin looks like a monument and a myth, but Forbes is using its cross chain technology and financial deployment to gently reinterpret the blockchain.
Next, I will expand what you are concerned about and what I see in the form of Q & A:
1. Is it investment or speculation to participate in Forbes?
Although we do not exclude speculation, there is no doubt that participating in Forbes is one of the best investment behaviors in 2020, no less than investing in bitcoin in 2013 and Ethereum in 2016. Forbes is a pure technology project, with no messy black box operation. As Forbes early deployed the ore field to facilitate the construction of cross chain system, early users can rent the Forbes BTC miner loaded with self-developed bitcoin ASIC chips by way of mortgage, with the strongest configuration on the ground. Moreover, in the process of mining, the early nodes do not even need to pay a penny, only mortgage deposit can deploy the physical miner. The income obtained can also participate in the early stage node plan carried out by Dao organization, and part of the income can be converted into GFS through Forbes wallet.
And the deposit is not a routine, all the mortgage deposits will be locked in the chain. With the shortening of the lease term, each day will be returned to the user's wallet through the "deposit smart contract", without any centralized individual and organization participation in the whole process. In this way, it is equivalent to zero risk investment! After all, Forbes, with its cryptology and open source spirit, is inherently powerful. What Forbes wants to change is the life of centralization!
And then there's no more. Jane is not simple.
2. Why do you like Forbes?
Very simple, blockchain 4.0
First of all, let's not talk about anything. Forbes has solved a problem - mining hegemony.
In the past, blockchain seems that nodes can enter and leave freely, but in fact, it needs a huge threshold to become nodes and obtain mining rewards. Whether it's bitcoin, you need to buy very expensive and complex mining equipment (ASIC miner), or EOS, Tron and other POS projects, and you need to hold a large number of coins to be elected as nodes. All in all, most of the current blockchain systems need very high mining costs, which in essence violates the principle of zhongbencong's blockchain design.
The powerful thing about Forbes is that it creatively constructs dpoc as a consensus mechanism of trunk chain (main chain). Dpoc is a kind of common understanding of POC. There is no big deployment threshold for mining with hard disk miner. As a result of the consensus between Forbes blockchain Multi Chain Design and dpoc, all mining machines that do not have the relay chain node selected can pack the interaction information between the parallel chain and the relay chain, and can also obtain the block reward. In essence, such a design realizes Zhongben Cong's idea that everyone can dig. Let alone Forbes to build a mine pool, to build the strongest mining machine that can dig out the Forbes token GFS.
With this in mind, which blockchain product can match.
Layout of Forbes
The vision of Forbes: to build the most universal distributed financial system in the world, driven by Forbes, the most widely used cross chain system in the world.
I saw two key words: cross chain, distributed Finance
Cross chain is the most urgent problem in current blockchain ecology. In the past 10 years, various blockchain systems have been deepening in security and performance, but no progress has been made in chain and chain scalability. As you can see, the chain and the chain is an island. Can EOS players and wave players break the bond?
In the human financial life, transaction, loan, personal credit, supply chain finance, stock, commodity... They are directly full of interaction and connection. It can be said that human beings are dealing with all kinds of transactions all the time. Can the isolated blockchain really solve the problem?
Forbes is born to be a global distributed financial system and truly a financial ecosystem. Imagine what a change it would be if you could smoothly carry out blockchain financial activities with foreign small partners. This pattern is too big for me to say. But please believe that if this is done, it can be described as a complete disaster.
3. Is it better to mine or invite new people?
Since this is my experience interpretation, I think: invite, boldly invite new people. Every time you invite one, you add a certain amount of calculation power. It's good to mine in Buddhism, but if you can participate in the birth of a great project, you can get more profits. Why not?
Let's take a different perspective: now that you recognize Forbes, you recognize its value. Or you're not going to dig, are you! So, why can't we add more yards! Since we are trying to change our destiny, this is the highest lever. If it does, which lever can be bigger than Forbes!
So, invest money or energy, and do what you can.
4. Do I want to join the Forbes pool project?
Do you want to do it.
They all recognize the value, so they can download the application directly.
My original intention:
First of all, GFS coin is a new mining model - POC hard disk mining that "everyone can dig, everyone can benefit". It avoids pow (proof of work workload) which is a large power consumption mode. In the initial stage of the main network online, Forbes opened the mine pool plan, leasing the mine machine at zero cost, becoming the earliest node of blockchain 4.0 representing the project, and obtaining the maximum benefit. Why not? You know, GFS production is also halved in four years. To dig now is to dig bitcoin before 2013, without cost.
Secondly, in this stage, we can also increase the number of invited nodes. After the completion of the mining pool plan, we can only rely on hard indicators to increase the computing power. Now we can also rely on our efforts to get more profits. Therefore, in the face of equal opportunities for all, this is a great opportunity to take the initiative. Still hesitant?
5. Blockchain is my knowledge blind area. What can I do if I don't understand cross chain knowledge?
First of all, you have to ask you, this is the excuse you don't want to get wealth?
Not only Forbes is your knowledge blind area, but blockchain is a knowledge blind area for ordinary people. However, you should know that in 2020, the State advocates blockchain, the central bank DCEP has been put into trial operation, and blockchain has been applied in many aspects. Are you still in your blind spot?
Of course, it's not good to pull the national flag. Let's talk about something practical. Opportunity always appears in new things. Ask, what's the matter with you, a solidified model? You have money or connections. I believe that choice is more important than effort. A road, if we choose the wrong direction at the beginning, the harder we work, the farther away we are from our goal.
Therefore, the knowledge blind spot is not my problem, but whether you have a heart willing to contact new things!
Among the miners I know, there is a 67 year old elder brother who has been a soldier, a factory, a traditional businessman and a cell phone. Do you still have his blind spot?
6. Will Forbes succeed?
To be honest, I don't know. But I know that it is the blockchain project that I hope to reach the most in 2020. For details, please refer to the second question, why I like Forbes. If you really question Forbes, you can choose to only participate in the "miner Alliance Plan" and choose to mine at zero cost. No matter how the Forbes project progresses, you can get the benefit of mining without cost. Why not? Besides, when the Forbes project is really implemented, you can decide whether to invest in GFS. I'm sure you will have your own judgment at that time.
7. What is the most important thing to dig GFS?
Insist, insist, or insist.
We must make full use of our efforts in the earliest planning activities of the mine pool. After all, mining at zero cost + inviting to increase the calculation power and increase the support in the wet season. At this stage, we must dig more coins and exchange more for GFS. Maybe the reward coins you dig out in three months can't be found in a year after you try to buy hard disk mining machines for nodes.
8. There are so many people who rent mining machines first. Do I have a chance?
People die more than people, and goods are thrown away more than goods. Don't compare with others, just be yourself.
God said, I can fulfill your one wish, but I will give you twice as many neighbors.
You will choose 10 million positive choices,
Or one less arm in the dark?
Mining is like this. Those old miners are your neighbors. Dare to own 10 million good, do not think about neighbors than you 10 million. Is that right? And when there are 10000 GFS, do you still want someone to have 100 more than you?
9. How much is GFS worth?
To be honest, I don't know. The number of GFS is 21 million bitcoin, and the price of bitcoin is about 60000 yuan. The GFS main network has just been launched. In some markets, its price has increased more than 10 times in five days, far exceeding the price of bitcoin before the half reduction. The miners who rent mining machines in advance are blessed.
As for the future, with the start of the implementation of blockchain financial facilities this year, GFS must be just the beginning. Where is the top? We witnessed it together.
10. Which do I want, kusd or usdt?
For now, it doesn't matter which one you use. Although usdt has a lot of potential risks, there are still many people using it. However, we all know that it will have a thunderstorm sooner or later.
As a cross chain gold stable currency, when cross chain finance begins to integrate into public life, kusd will show its power, which is better than issuing a usdt once in a chain. Moreover, more than 95% of the value of each kusd is based on gold, which can be exchanged by major gold exchanges in the world. The stability of gold. Have you seen it clearly in this epidemic? This is beyond the dollar.
Thank you for inviting Horizen to the GPU mining AMA!submitted by Blockops to gpumining [link] [comments]
ZEN had a great run of GPU mining that lasted well over a year, and brought lots of value to the early Zclassic miners. It is mined using Equihash protocol, and there have been ASIC miners available for the algorithm since about June of 2018. GPU mining is not really profitable for Horizen at this point in time.
We’ve got a lot of miners in the Horizen community, and many GPU miners also buy ASIC miners. Happy to talk about algorithm changes, security, and any other aspect of mining in the questions below. There are also links to the Horizen website, blog post, etc. below.
So, if I’m not here to ask you to mine, hold, and love ZEN, what can I offer? Notes on some of the lessons I’ve learned about maximizing mining profitability. An update on Horizen - there is life after moving on from GPU mining. As well as answering your questions during the next 7 days.
Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Author: Rolf Versluis - co-founder of HorizenIn GPU mining, just like in many of the activities involved with Bitcoin and cryptocurrencies, there is both a cycle and a progression. The Bitcoin price cycle is fairly steady, and by creating a personal handbook of actions to take during the cycle, GPU miners can maximize their profitability.
Maximizing profitability isn't the only aspect of GPU mining that is important, of course, but it is helpful to be able to invest in new hardware, and be able to have enough time to spend on building and maintaining the GPU miners. If it was a constant process that also involved losing money, then it wouldn't be as much fun.
Technology ProgressionFor a given mining algorithm, there is definitely a technology progression. We can look back on the technology that was used to mine Bitcoin and see how it first started off as Central Processing Unit (CPU) mining, then it moved to Graphical Processing Unit (GPU) mining, then Field Programmable Gate Array (FPGA), and then Application Specific Integrated Circuit (ASIC).
Throughout this evolution we have witnessed a variety of unsavory business practices that unfortunately still happen on occasion, like ASIC Miner manufacturers taking pre-orders 6 months in advance, GPU manufacturers creating commercial cards for large farms that are difficult for retail customers to secure and ASIC Miner manufacturers mining on gear for months before making it available for sale.
When a new crypto-currency is created, in many cases a new mining algorithm is created also. This is important, because if an existing algorithm was used, the coin would be open to a 51% attack from day one, and may not even be able to build a valid blockchain.
Because there's such a focus on profitable software, developers for GPU mining applications are usually able to write a mining application fairly rapidly, then iterate it to the limit of current GPU technology. If it looks like a promising new cryptocurrency, FPGA stream developers and ASIC Hardware Developers start working on their designs at the same time.
The people who create the hashing algorithms run by the miners are usually not very familiar with the design capabilities of Hardware manufacturers. Building application-specific semiconductors is an industry that's almost 60 years old now, and FPGA’s have been around for almost 35 years. This is an industry that has very experienced engineers using advanced design and modeling tools.
Promising cryptocurrencies are usually ones that are deploying new technology, or going after a big market, and who have at least a team of talented software developers. In the best case, the project has a full-stack business team involving development, project management, systems administration, marketing, sales, and leadership. This is the type of project that attracts early investment from the market, which will drive the price of the coin up significantly in the first year.
For any cryptocurrency that's a worthwhile investment of time, money, and electricity for the hashing, there will be a ASIC miners developed for it. Instead of fighting this technology progression, GPU miners may be better off recognizing it as inevitable, and taking advantage of the cryptocurrency cycle to maximize GPU mining profitability instead.
Cryptocurrency Price CycleFor quality crypto projects, in addition to the one-way technology progression of CPU -> GPU -> FPGA -> ASIC, there is an upward price progression. More importantly, there is a cryptocurrency price cycle that oscillates around an overall upgrade price progression. Plotted against time, a cycle with an upward progressions looks like a sine wave with an ever increasing average value, which is what we see so far with the Bitcoin price.
Cryptocurrency price cycle and progression for miners
This means mining promising new cryptocurrencies with GPU miners, holding them as the price rises, and being ready to sell a significant portion in the first year. Just about every cryptocurrency is going to have a sharp price rise at some point, whether through institutional investor interest or by being the target of a pump-and-dump operation. It’s especially likely in the first year, while the supply is low and there is not much trading volume or liquidity on exchanges.
Miners need to operate in the world of government money, as well as cryptocurrency. The people who run mining businesses at some point have to start selling their mining proceeds to pay the bills, and to buy new equipment as the existing equipment becomes obsolete. Working to maximize profitability means more than just mining new cryptocurrencies, it also means learning when to sell and how to manage money.
Managing Cash for MinersThe worst thing that can happen to a business is to run out of cash. When that happens, the business usually shuts down and goes into bankruptcy. Sometimes an investor comes in and picks up the pieces, but at the point the former owners become employees.
There are two sides to managing cash - one is earning it, the other is spending it, and the cryptocurrency price cycle can tell the GPU miner when it is the best time to do certain things. A market top and bottom is easy to recognize in hindsight, and harder to see when in the middle of it. Even if a miner is able to recognize the tops and bottoms, it is difficult to act when there is so much hype and positivity at the top of the cycle, and so much gloom and doom at the bottom.
A decent rule of thumb for the last few cycles appears to be that at the top and bottom of the cycle BTC is 10x as expensive compared to USD as the last cycle. Newer crypto projects tend to have bigger price swings than Bitcoin, and during the rising of the pricing cycle there is the possibility that an altcoin will have a rise to 100x its starting price.
Taking profits from selling altcoins during the rise is important, but so is maintaining a reserve. In order to catch a 100x move, it may be worth the risk to put some of the altcoin on an exchange and set a very high limit order. For the larger cryptocurrencies like Bitcoin it is important to set trailing sell stops on the way up, and to not buy back in for at least a month if a sell stop gets triggered. Being able to read price charts, see support and resistance areas for price, and knowing how to set sell orders are an important part of mining profitability.
Actions to Take During the CycleAs the cycle starts to rise from the bottom, this is a good time to buy mining hardware - it will be inexpensive. Also to mine and buy altcoins, which are usually the first to see a price rise, and will have larger price increases than Bitcoin.
On the rise of the cycle, this is a good time to see which altcoins are doing well from a project fundamentals standpoint, and which ones look like they are undergoing accumulation from investors.
Halfway through the rise of the cycle is the time to start selling altcoins for the larger project cryptos like Bitcoin. Miners will miss some of the profit at the top of the cycle, but will not run out of cash by doing this. This is also the time to stop buying mining hardware. Don’t worry, you’ll be able to pick up that same hardware used for a fraction of the price at the next bottom.
As the price nears the top of the cycle, sell enough Bitcoin and other cryptocurrencies to meet the following projected costs:
As the cycle has peaked and starts to decline, this is a good time to start investing in mining facilities and other infrastructure, brush up on trading skills, count your winnings, and take some vacation.
At the bottom of the cycle, it is time to start buying both used and new mining equipment. The bottom can be hard to recognize.
If you can continue to mine all the way through bottom part of the cryptocurrency pricing cycle, paying with the funds sold near the top, you will have a profitable and enjoyable cryptocurrency mining business. Any cryptocurrency you are able to hold onto will benefit from the price progression in the next higher cycle phase.
An Update on Horizen - formerly ZenCashThe team at Horizen recognizes the important part that GPU miners played in the early success of Zclassic and ZenCash, and there is always a welcoming attitude to any of ZEN miners, past and present. About 1 year after ZenCash launched, ASIC miners became available for the Equihash algorithm. Looking at a chart of mining difficulty over time shows when it was time for GPU miners to move to mining other cryptocurrencies.
Horizen Historical Block Difficulty Graph
Looking at the hashrate chart, it is straightforward to see that ASIC miners were deployed starting June 2018. It appears that there was a jump in mining hashrate in October of 2017. This may have been larger GPU farms switching over to mine Horizen, FPGA’s on the network, or early version of Equihash ASIC miners that were kept private.
The team understands the importance of the cryptocurrency price cycle as it affects the funds from the Horizen treasury and the investments that can be made. 20% of each block mined is sent to the Horizen non-profit foundation for use to improve the project. Just like miners have to manage money, the team has to decide whether to spend funds when the price is high or convert it to another form in preparation for the bottom part of the cycle.
During the rise and upper part of the last price cycle Horizen was working hard to maximize the value of the project through many different ways, including spending on research and development, project management, marketing, business development with exchanges and merchants, and working to create adoption in all the countries of the world.
During the lower half of the cycle Horizen has reduced the team to the essentials, and worked to build a base of users, relationships with investors, exchanges, and merchants, and continue to develop the higher priority software projects. Lower priority software development, going to trade shows, and paying for business partnerships like exchanges and applications have all been completely stopped.
Miners are still a very important part of the Horizen ecosystem, earning 60% of the block reward. 20% goes to node operators, with 20% to the foundation. In the summer of 2018 the consensus algorithm was modified slightly to make it much more difficult for any group of miners to perform a 51% attack on Horizen. This has so far proven effective.
The team is strong, we provide monthly updates on a YouTube live stream on the first Wednesday of each month where all questions asked during the stream are addressed, and our marketing team works to develop awareness of Horizen worldwide. New wallet software was released recently, and it is the foundation application for people to use and manage their ZEN going forward.
Horizen is a Proof of Work cryptocurrency, and there is no plan to change that by the current development team. If there is a security or centralization concern, there may be change to the algorithm, but that appears unlikely at this time, as the hidden chain mining penalty looks like it is effective in stopping 51% attacks.
During 2019 and 2020 the Horizen team plans to release many new software updates:
When the governance is transitioned, the project should be as decentralized as possible. The goal of decentralization is to enable resilience and preventing the capture of the project by regulators, government, criminal organizations, large corporations, or a small group of individuals.
Everyone involved with Horizen can be proud of what we have accomplished together so far. Miners who were there for the early mining and growth of the project played a large part in securing the network, evangelizing to new community members, and helping to create liquidity on new exchanges. Miners are still a very important part of the project and community. Together we can look forward to achieving many new goals in the future.

After sustained growth over the past three months, computing power on the bitcoin network has seen a fallback as the summer rainy season trails off in China.
According to data from Poolin, the world’s largest bitcoin mining pool by real time hash rate, bitcoin’s seven-day average computing (or hashing) power has dropped to around 90 exahashes per second (EH/s) since Oct. 24, signaling that some miners have been unplugging from the network. It had previously been estimated that the hash rate would go above the 100 EH/s threshold by the end of 2019
As a result of the power drop, data from mining pool service BTC.com estimates that bitcoin’s difficulty – a measure of how hard it is to compete for mining rewards on the world’s top cryptocurrency by market value – will decrease by 1.5 percent when it’s set to adjust in about seven days.
Bitcoin’s mining difficulty had reached an all-time-high at 13.69 trillion on Oct. 24, following a 38 percent increase since early August. The climb resulted mainly from an increase in miners’ hashing power made possible by the abundant and cheap hydroelectricity in China’s southwestern provinces.
Mining difficulty is designed to adjust itself to go up or down about every 14 days, based on whether the hashing power on the network in the two-week cycle increases or declines, respectively. The Oct. 24 difficulty record followed a jump in the 14-day average hash rate to an all-time-high at 97.90 EH/s.
Poolin’s co-founder Chris Zhu said in a recent WeChat post that one main reason for the fallback over the last week is the gradual end of this year’s rainy season in China. As a result, some hydropower stations in China’s Sichuan province – estimated to account for 50 percent of bitcoin’s global computing power – no longer have the capacity to generate enough energy to support mining activities.
Miners without sufficient hydropower supply would have to shut down their operations or relocate to other provinces like Xinjiang or Inner Mongolio, where mining farms have a more stable, but more expensive, power supply generated from fossil fuel plants.
Xun Zheng, CEO of Hashage, which owns mining facilities in China’s southwestern Sichuan province, echoed Zhu’s comments, adding that even if some may still be able to find a hydropower resource, the cost has gone up from $0.04 per kilowatt-hour (kWh) in the summer to around $0.05.
Further, bitcoin’s sudden price drop on Oct. 23 to below $7,500 could have resulted in a large scale of shutdown of older but widely used mining models like the AntMiner S9 made by Bitmain. The S9’s profit break-even price point is between $7,000 to $7,500. However, the price’s significant rebound since last weekend may have stopped that panic.
The fact remains, though, that the profitability of the S9 and other similar modes made by Bitmain’s rival miner makers, is a critical issue for their utility lifespan. And that may soon be affected by the higher winter cost of electricity in China, as well as the scheduled halving of bitcoin mining rewards in May 2020 – before next year’s rainy season.
According to a miner profitability index provided by Poolin and its rival F2pool, at bitcoin’s current price and an electricity cost of $0.05 kWh, the mining profit margin of models like S9 is about 30 percent.
Some, like INBTC, a sister company of Poolin, are currently making efforts to extend the life of the S9 miner by merging two units into one in an attempt to generate a higher ratio of hashing power over electricity consumption. That would allow a higher daily profit margin than would be achieved using two individual units, though it remains to be seen if such a method can be proven to work and adopted on a large scale.
