Hello. 👋🏻 Today we will tell you about ACIS-mining and its 3 best algorithms.submitted by VS_community to pyrk [link] [comments]
📌 With the advent of ASICs for mining, it became possible to mine Bitcoin in much larger quantities than using video cards. ASIC is an integrated circuit specialized to solve a specific problem, in our case, only for bitcoin mining. These schemes are many times more profitable than video cards, because with more power (hash calculation speed) they consume much less energy. This served as a good reason to create a cryptocurrency mining business.
📌 In bitcoin and other blockchain systems, the complexity of mining depends on how quickly the miners find the block. Compared with the GPU and CPU, specialized #ASIC miners solve #PoW puzzles better and are therefore able to quickly find new blocks.
📌 Since PoW is still the preferred mining consensus mechanism, we propose to take a multiple algorithm approach. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: #SHA256, #Scrypt, and #X11.
🔹 The SHA-256 algorithm has a number of advantages over other information protection technologies. Over the years of use in the cryptocurrency industry, he has shown his resistance to various hacking attempts.
🔹 Scrypt is a cryptocurrency mining algorithm that was previously interesting to many single miners in view of its resistance to the so-called “hardware attack”. The speed of creating blocks in a Scrypt-based blockchain is about 30 seconds. The hashrate, like Ethash, is measured in Megahash per second. Scrypt, first of all, became popular due to its use in Litecoin #cryptocurrency.
🔹 X11 is an encryption algorithm in which eleven are used instead of one function. This means that this technology can provide a high degree of security, because in order to harm the system, an attacker will have to crack all 11 functions, which is very unlikely, because the changes made will be visible after breaking the first function, and developers will have a lot of time to protect the system before the hacker reaches the eleventh function.
Since these miners are already in wide use, the distribution of mining should be fair and even. Furthermore, the use of three different algorithms results in a far less chance of any single person gaining a majority hash rate share. Lastly, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining.

I want to clear out the air about Ethereum mining. The GPU mining vs Asic mining, is Ethereum now Asic mining Algorithm. Can RX5700 most efficient Graphic cards for ETH mining Compete with Asic miner A10.
For the last day i have been working on some stats and ROI for 2 types of investment for 12xGPU RX5700 MineBox 12 mining rig and Innosilicon A10 ETH ASIC miner. My goal was to let the data speak about it self and then make a decision what is better investment for ethereum mining GPU or ASIC. Im compering 2 most efficient miners :
I have created google spreadsheet and inserted the GPU data and performance by the current currencies price and mining profitability. Included also my thoughts about advantages and disadvantages using GPU or Asic miner:
Opinion based on mining profit data. We can see that MineBox 12 ROI if electric price is free or very cheap is faster then ASIC miner A10. And even at 0.10c a kw/h at current Ethereum price there is only 80day difference on Equipment payback time. But the biggest thing is for example when your miners are paid back your investment. You still are available to resell your MineBox 12 hardware for other use case or just mine different coins. Where with Innosilicon A10 you can throw it into bin as soon as ETHASH coins are not profitable to mine. This is the biggest downside of Asic miners. So to answer your question is ETH asic mining coin. My answer would be Yes ASIC miners are slightly more profitable , BUT they are not worth the risk you are getting by buying one. Also you can see clearly that GPU miners has lot more advantages then Asic miners. The difference on ETH miners are not so noticeable then like it was Bitcoin GPU vs ASIC mining. There is still profit to be made with GPUs mining ETH. If ETH switches to new POW ProgPOW , again another benefit for GPU rigs as the same GPUs are quite efficient mining ProgPow. Buying and Asic miner there is to much risk, saying from experience. Have lost a lot of money, my last adventure bought 5xAntminer S17 back in November and 4 of them hashing boards stopped working after 1st week. Not counting the previous purchases Antminer D3 etc..
Let me guys know what you think about this, would your rather use ASIC miner for mining ETH of GPU miner?

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.

The whole crypto world discusses how Ethereum will switch from Proof of Work to Proof of Stake now. This change can significantly affect the cryptocurrency market. What are the positive and negative sides of PoW and PoS?submitted by CoinjoyAssistant to ethtrader [link] [comments]
Cryptocurrencies can be divided into two types: those that can be mined (Bitcoin, Litecoin, Monero) and pre-mined ones (Ripple, Stellar, Cardano, EOS, NEO).
What is the big difference?Although they differ in the method of generation, the basis of both types of crypto is the same: verification. Every transaction processed by the network must be verified by someone to ensure that virtual money has not been spent twice. Here we are talking about the difference in the verification process. Transaction groups are combined into a block; after verification, the block joins other previously confirmed blocks, and create a chain of transactions, or blockchain.
PoW: Mined CryptoMining is a process in which individuals, groups, or companies solve complex mathematical equations to verify transaction blocks using powerful computers. These math problems are part of the encryption process that protects transactions from cybercriminals and third party access.
The first who solves the problem and signs a block of transactions receives a reward. The miner, who confirmed the block of transactions e.g. in the Bitcoin network, receives a reward in BTC.
Disadvantages of Mined Crypto
PoS: Non-Mined CryptoAt the other end of the spectrum are pre-mined cryptocurrencies such as Ripple (XRP), Stellar, Cardano, EOS, and NEO.
In the PoS model, super-powered computers are not needed, and participants do not compete for the right to sign the next block. Thus, the costs of this approach are significantly lower. Transaction verification is carried out by cryptocurrency owners. The more cryptocurrencies you have, the longer you own it, the higher the probability that you will be selected to check the transaction block.
Certain mechanisms are built into the system that prevents the dominance of large cryptocurrency holders over the verification process. There are many random ways to select owners who get the right to sign a transaction block. This ensures that small holders have a chance to participate in the process.
Disadvantages of Non-Mined CryptoDespite the fact that the costs of the Proof-of-Stake method are lower, PoS has its drawbacks.
Which method is better?Both methods have their pros and cons. Nevertheless, sooner or later, some of the largest mined currencies (e.g. BTC) will reach their token limit. At this point, they will have to switch to Proof-of-Stake. Since it significantly reduces power consumption and doesn't require powerful computers, gradually all crypto including BTC will switch to a non-mined model just like Ether did.

With cryptocurrencies entering the mainstream with a bang, more and more people every single day develop an interest in this new and strange world of blockchain. A lot of these people come to cryptos because they had heard that it’s possible to make money from them. If you’re one of those people, you’re in luck, because today I want to tell you how to mine cryptocurrency.
Understanding MiningTo put it into very simple terms, crypto mining is a process in which a machine performs certain tasks to obtain a little bit of cryptocurrency. This is the biggest TL;DR possible, so let’s branch out a bit, shall we? Imagine that you have a machine that mines crypto coins. We’ll talk about the specific types of machines later on in the tutorial, but for example’s sake, let’s just say that it’s your own, personal computer and you’re trying to figure out how to mine cryptocurrency. That is a very short and simple way of defining what is cryptocurrency mining. Now let’s move on to what you came here to see; how to mine cryptocurrency.
Cryptocurrency MiningThere are a few ways you could go about cryptocurrency mining. I’ll cover the main ones here, and start from the easiest one – cloud mining.
Method #1 – Cloud MiningIf you’re looking for crypto mining ways, cloud mining is probably the most popular way to mine cryptocurrencies without having to lift a finger. Cloud mining is a process where you pay someone (most often it’s a big corporation) a specific amount of money and “rent out” their mining machine called a “rig”, and the process of mining itself. This rent lasts for an agreed-upon period, through which all of the earnings that the rig makes (minus the electricity and maintenance costs) are transferred to your cryptocurrency wallet. The people (companies) that offer these cloud mining services usually have huge mining facilities with multiple farms (tens or hundreds of rigs stacked and operating together) at their disposal and know perfectly well how to mine cryptocurrency.
Cloud mining has become so popular mainly because it offers the possibility to participate in the world of cryptocurrencies for people who might not have enough money to buy their rigs or who perhaps simply aren’t interested in owning a rig. There are two options of cloud mining – free and paid. Naturally, a lot of people that are looking for ways to mine cryptocurrency would gravitate towards the “free” options, but it does have its drawbacks (very slow mining speeds, extra conditions, etc.). Paid cloud mining usually works like this: It is usually expected that you’ll break even at around the half-a-year – one year mark, and then profit from that point onwards. No one can know for sure, though, because the prices of cryptocurrencies are very volatile and their prices tend to sway by quite a bit.
Method #2 – CPU MiningCPU mining utilizes processors to mine cryptocurrencies. It used to be a viable option back in the day, but currently, fewer and fewer people choose this method of mining cryptocurrency daily. There are a couple of reasons why that is. First of all, CPU mining is EXTREMELY slow. You could go on for months without noticing the smallest amount of revenue. It’s also usually not worth it – you make very little amounts of money, but you probably spend ten times that amount on electricity and cooling. The problem mitigates itself by a bit if you can find a place that has nice cooling and cheap electricity bills, but that’s rarely the case.
So why do people still even use CPU mining, then?
Well, basically because anyone with a desktop computer could do it. All you need to be able to mine using the CPU method is just a computer and a couple of programs. It is possible to do it with a laptop, but it is VERY STRONGLY NOT ADVISED. Your laptop will probably fry and overheat in a matter of a couple of hours. The fact that it’s so easy to start cryptocurrency mining attracts new CPU miners every day. Some people that are looking for how to mine cryptocurrency don’t care about the details – they just want to start the process as soon as possible, and in any way possible.
Method #3 – GPU MiningGPU mining is probably the most popular and well-known method of mining cryptocurrencies. If you google “cryptocurrency mining”, GPU rigs are going to be some of the first things that you’ll see.
Cloud miners, for example, use GPU rigs for their services. And these guys are professionals that sometimes have hundreds if not thousands of rigs, so they probably know what they’re doing, right?
GPU mining is very popular because it’s both efficient and relatively cheap. Don’t get me wrong, the construction of the rig itself tends to be costly – but when it comes to its hash speed and the general workforce, the GPU mining rig is great. GPU rigs utilize graphics cards to mine cryptocurrencies. One standard rig is made out of a processor, a motherboard, cooling, rig frame and – of course – a few (2 – 8) graphics cards.A typical price for a well-performing and nicely built GPU mining rig aims to be around the $3000 price range. It is a hefty investment but will pay off much faster than, let’s say, a CPU miner. People looking for ways to mine cryptocurrency should check them out.
Method #4 – ASIC MiningASICs (Application-Specific Integrated Circuits) are special devices that are designed explicitly to perform a single task, which in this case is crypto mining. ASICs are very well known and treasured because they produce insane amounts of cryptocurrency when compared to its competitors’ GPU and CPU. But if they are so good, why didn’t I mention them sooner?
Well, mostly because they’re a big subject of controversy. You see, when the ASIC company announced its new version of the machine, the announcement caused an uproar in the cryptocurrency community. Many people have called for an outright ban on these machines.
Why? Because ASICS are so powerful, they rob other miners who are using GPU or CPU rigs of the possibility to keep up both in hash speeds and in earnings. Also, ASICS have twisted the economy of certain specific cryptocurrencies – imagine if the majority of earnings would go to one miner with an ASIC farm, what kind of chaos that would ensue.
The Best Method to Mine CryptocurrencyNow that you have an understanding of how to mine cryptocurrency and about all of the different ways to do it, which one is the best way?
The method that suits you the most depends solemnly on a few key details: are you willing to spend some initial money? If so, how much? Do you want to OWN a rig? Do you even want to do it with a rig?
Which Cryptocurrency to Mine?Your choice of gear should also depend on the type of cryptocurrency mining that you’ve decided to do. Some of the obvious favorites would be Bitcoin, Ethereum or Dash. Keep in mind, though, that Bitcoin mining is probably the trickiest of them all – since the coin is so popular, there are many miners around the world tuning into the few pools that there are and trying to snatch at least a small bit of Bitcoin. This might result in you waiting for countless hours until the first drops of Bitcoin start coming in.
Keeping that in mind, your best bet would probably be to stick with Ethereum or some other less-popular cryptocurrency. Depending on your method of choice, check out the prices, calculate when your return on investment would happen, do some math and you’ll figure it out in no time!
ConclusionAs you’ve probably noticed, there are many different ways on how to mine cryptocurrency. These are simply the main methods – if you’d like, you could even forget about mining and jump into Bitcoin faucets – but that’s a whole different story for a whole different day. But it’s an option!
One thing that you should not only remember, but also do right away is to create a cryptocurrency wallet. Decide on the type of cryptocurrency that you want to mine and simply look up the wallet options for that currency. You’ll have no problems finding one for coins like Bitcoin, Ethereum or Litecoin, but if you want to mine the less-known currencies, then you might need to search for a bit until you find a reputable wallet.
Getting a secure and reputable wallet is the most important task when you’re starting with cryptocurrency mining. Imagine if you’d be mining for a year and all of your savings would be stolen only because you didn’t pay enough attention while choosing the wallet and picked a fishy one that got hacked into.
If you’re serious and are looking for ways on how to mine cryptocurrency, I would suggest buying a hardware wallet – they are the safest and most trustworthy cryptocurrency wallets out there.
Well, this is the end of my tutorial on crypto mining. We’ve covered a few different topics and explored the different varieties of cryptocurrency mining methods. Remember – the method that suits you the most will depend solemnly on what you want and what kind of resources you have, so choose carefully! If you do decide on giving mining a chance, I wish you the best of luck!
