ACIS-mining and its 3 best algorithms
Hello. 👋🏻 Today we will tell you about ACIS-mining and its 3 best algorithms. 📌 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.

ASICs are coming to the Ethereum mining industry, and small independent miners are virtually doomed. 2Ether has come up with a solution — the third element in our dynamic block reward system. But before we explain it, we’ll have to talk about Ethereum ASICs. If you don’t know that much about Ethereum, you might be surprised to learn that ASICs for mining ETH actually exist. Isn’t Ethereum’s algorithm — Ethash — supposed to be ASIC-resistant? If it isn’t then why is everyone still mining using GPUs? Well, Ethash is indeed much less ASIC-friendly than the algorithm of Bitcoin. It doesn’t mean that you can’t make ASIC chips for mining ether, though. It’s just that it’s difficult to make ASICs that would be much more efficient than graphic cards (GPUs). The efficiency of a piece of mining hardware is calculated as a ratio of power (measured in kilowatt hours) to hash power (measured in megahash per second). So for example, if you have two devices that both produce 50 MH/s, but one of them consumes 1 kWh, and the other consumes 2 kWh, then the first device is twice more efficient. ASICs cost a lot of money to design, and their market price is high. So it only makes sense to buy an ASIC if it gives you a serious advantage over other types of hardware. You should also keep in mind that if the algorithm changes, you’ll need to replace your ASIC with a new model. Such chips are built to carry out one task and one task only — that’s why they are called application-specific integrated circuits (that’s how the acronym is deciphered). Now, the first ASICs for Ethereum came out in April 2018, and they were more than a curious gadget than a serious rival to GPUs. Vitalik Buterin said that they were not a threat and the best action would be no action. But the situation changed. Soon, there were ASICs twice as efficient as the best graphic cards. Still, it wasn’t enough to justify the price difference. Finally, in late September 2019, Chinese manufacturer and distributor of mining hardware Canaan announced that it would start selling a new ASIC that is 5 to 7 times more efficient than the leading GPU models.Its W/MHs ratio is just 0.68–7.5 times better compared to AMD Vega 64 and 5.3 times better than AMD RX570. What does this mean for Ethereum mining? When such models go on sale, whoever can afford them will be able to extract very high profits. GPU miners will be at a disadvantage. And if you have only a small rig with a couple of GPUs at home, your prospects are grim. You might ask: can’t Ethereum devs do something — say, change the algorithm? Bitcoin algo changes regularly, after all. Unfortunately, Ethereum works differently, so every algorithm change would require a hard fork — with all the consequences it entails. The devs have been talking about introducing a new consensus protocol called ProgPOW (Programmable Proof of Work). It would make the algorithm change regularly and ensure ASIC resistance. But Vitalik Buterin believes that the real goal is a switch to Proof of Stake, not tweaking PoW. What other options are there to protect small miners from the upcoming wave of ASICs? In our next post, we’ll explain how 2Ether plans to deal with this problem. https://2ether.com/ Web site — https://2ether.com/ Twitter — https://twitter.com/2Ether_ Discord — https://discord.gg/TuqG4py Facebook — https://www.facebook.com/2Ethe Reddit — https://www.reddit.com/use2Ether Medium — https://medium.com/@2ether Teletype — https://teletype.in/@2ether Telegram — https://t.me/ether2support Telegram chat — https://t.me/blockchain_2ether
There has been a lot of talk about botnets, and potential solutions to help improve the profitability of mining XMR. I want to help shed some light on this. This post is my attempt to take a look at one of the proposed solutions and to clear up some misunderstandings surrounding this problem. I do want to preface this by saying that I really don't know shit about shit. I a 21 year old college kid who like to pretend I can write code. I don't have any real knowledge on the matter, so take what I say with a grain of salt. Make Monero work only on GPUs, and still be ASIC Resistant So, this is a fun idea, but I think it is rooted in some misunderstandings about what is actually going on under the hood of the CryptoNote algorithm. The first thing that I want to touch on is this idea of "ASIC Resistance" because I think it is a little misleading. People think that there is some magic "scratchpad" that makes BitMain and other ASIC companies shake in their boots. This is just silly. Monero is not ASIC resistant. Let me repeat that: MONERO IS NOT ASIC RESISTANT, and to help illustrate this point it is helpful to think about some other algorithms like SHA256 or Scrypt. Think about these algorithms for a little bit. They were invented before the hardware that implemented them was produced. That is why people could straigh up mine Bitcoin back in the day. SHA256 existed, but then some smart engineers figured out how to make a chip that would run that algorithm faster. Same thing with Blake2s or Scrypt, algorithms came, engineers made hardware to suit it. CryptoNote, however, went in the opposite direction. For Bitcoin people fine tuned hardware to fit the algorithm, the CryptoNote developers on the other hand fine tuned their algorithm to fit the hardware. When people say
Monero is ASIC resistant
They think that this means that nobody will be able to build an ASIC to mine for the token. However, what they are actually saying is
The ASICs for Monero already exists, and it is everywhere. Everyone already has the Monero ASIC in their home PC.
See, people think that Monero is some special unicorn, and that companies like BitMain, Intel, or Nvidia are not able to outsmart the algorithm to make any "real ASICs." That is just not true. If Intel wanted, they could make a machine tomorrow that would crunch a few megahashes per second. So could Nvidia, or AMD, or BitMain. The reason that they dont is because fast memory is expensive. Any of them could make such a product, they dont because nobody would buy it. It would cost so so so much more than you would ever make mining with it. Monero is only "ASIC resistant" because the supply of fast memoery is low, if this changes then Monero if fucked. CryptoNote is a proof-of-work algorithm, yes, but really it is more like a proof-of-memory-speed algorithm. You can 100% make an ASIC for that. This brings be to why the algorithm cannot be "fixed" to work well on GPUs while still being ASIC resistant. GPUs have slow memory. If you take a proof-of-fast memory algorithm and make it work better on slow memory then you will be trading the only thing that makes it "ASIC Resistant". They are mutually exclusive. It literally cannot both be optimized for GPUs while still keeping BitMain out; because BitMain essentially makes optimized GPUs. In closing It is just not a thing. If I got anything wrong absolutely call me out, I want this post to help bring understanding and if is is actually just muddying the water i will take it down :D Let me know your thoughts :D Edit: Here, when i use the term ASIC i am loosely saying "the most profitable machine to mine for a token"
Help me understand NiceHash statistics chart (the units).
I am specifically interested in labels (near mouse) on the following screen: http://i.imgur.com/uwmI0P8.png First says: Paying: 4.2908 BTC/MSol/Day Second says: Hashing speed: 25.26 MSol/s And my interpretation of them: First: NiceHash is paying me 4.2908 Bitcoins for one Megahash (Mega solution) per day. So if I understand it right: If I could deliver MSol (Megahash) per every day, I would earn 4.2908 bitcoins (probably minus fee) every day. Second: As this number is very large (and in MSol/s unit!) I assume that this is currently available hashing speed (from all active miners). Do I understand those right?

So say that I have a device that is operating a given frequency. For easy math, one hertz (one cycle per second). For each hertz, it uses one watt more. Therefore, its energy efficiency is 1W/Hz. Obviously, this could be simplified to 1 J/cycle, or 1 cycle/J. However, if the people I'm talking to don't know the unit "watt" or "cycle", and I want to write 1 J/s/cycle/s, what's the best way to do this? Do I use parenthesis around each part [ex. 1 (J/s)/(Cycle/s)]? Or say they know the term "watt", but not "hertz". Would that be: 1 W/(Cycle/s)? I know this sounds trivial, but the application here is in bitcoin mining, where you measure MH/s/$ and MH/J (but nobody know MH on its own, or J on its own, so you have to do MH/s/J/s). Note that MH = megahashes = million hashes (which is the analog of cycles in the example).
I have just started mining bitcoins with my computer, but don't want to invest in a mining rig. My current hashrate goes along the lines of about 92 Megahashes per second with two GeForce GT 755M, is there any way to increase my hashrate?
I am trying mining for the first time with litecoin (my bitcoin mining experience is also near nil) and I was wondering what unit cgminer is reporting for my hashrate because I am confused... It says 23.70M/23.56Mh/s. From my small understanding of litecoin this would be extremely fast, no? This is impossible though because my graphics card is ancient and terrible. I hear about hashrates for most video cards being in the Kh/s range, not Mh/s. Is this some unit such as "micro-hash" or "milli-hash per second" instead of megahash per second? Also, I am starting my mining experiment through p2pool.org, about how many days would I have to wait at that hashrate to get one share? edit: actually after not waiting more than 10 min I noticed that cgminer says "best share: 4". So Ive mined atleast one share?
1 mega hash per second is one million (1,000,000) hashes per second. 1 giga hash per second is one billion (1,000,000,000) hashes per second. 1 tera hash per second is one trillion ... Obviously, hashes per second can be computed by some sort of some of hashes per time frame, divided by time in frame. like... 0% of mining hardware will deliver its full-on however-millions-of-hashes directly to the mining software. From what I can tell, there's 2 other ways to measure the metric: # of qualified nonces to produce hash. As far as I know, this figures in the 'difficulty 1' mask ... Hash per second is an SI derived unit representing the number of double SHA-256 computations performed in one second, referred to as hash rate.It is usually symbolized as h/s (with an appropriate SI prefix).. Use in hardware specifications. The hash rate is the primary measure of a Bitcoin miner's performance. In 2014, a miner's performance was generally measured in Ghash/s, or billions of ... Hashrate (Hash per second, h/s) is an SI-derived unit representing the number of double SHA-256 computations performed in one second in the bitcoin network for cryptocurrency mining.
