Ethminer is an Ethash/ProgPoW GPU mining worker: with ethminer you can mine every coin which relies on an Ethash Proof of Work thus including Ethereum, Ethereum. Ethash, ProgPoW, Equihash, CuckooCycle GPU Miner C/C++ implementation of Ethash and ProgPoW – the Ethereum Proof of Work algorithms. “ProgPoW is a proposal to change the Proof of Work function for Ethereum from the current Ethash algorithm (which can be effectively performed.

As a consequence, a discussion about the increasing centralization of the Ethereum network through ASIC mining was initiated. In addition, numerous GPU miners complained about a lack of profitability. ProgPoW was then submitted under EIP and discussed for months within the Ethereum community and in the Ethereum core developer calls. The first preliminary approval was already given on January 4, The Ethereum Cat Herders were commissioned to carry out an audit. This audit is currently still in progress.
Follow us for the latest crypto news! Worries about a possible hard fork Although ProgPoW has already received the approval of the core developers several times, the discussion is still ongoing. A few express concern about the possibility of splitting the community. Some opponents of the proposal fear that exchanges could run both Ethereum versions, with and without ProgPoW.
The only optimizations available are: Remove the graphics pipeline displays, geometry engines, texturing, etc Remove floating point math A few ISA tweaks, like instructions that exactly match the merge function These would result in minimal, roughly 1.
This is much less than the 2x for Ethash or 50x for Cryptonight. Rationale for PoW on Commodity Hardware With the growth of large mining pools, the control of hashing power has been delegated to the top few pools to provide a steadier economic return for small miners. High barrier to entry: Initial miners are those rich enough to invest capital and ecological resources on the unknown experiment a new coin may be.
Thus, initial coin distribution through mining will be very limited causing centralized economic bias. No obvious decentralization of control even with decentralized mining: Once large custom ASIC makers get into the game, designing back-doored hardware is trivial. ASIC makers have no incentive to be transparent or fair in market participation. The protection that this offers when the coin is unknown also makes it an attractive target for a dedicate mining ASIC company as soon as it becomes useful.
Therefore, ASIC resistance is: the efficiency difference of specialized hardware versus hardware that has a wider adoption and applicability. A smaller efficiency difference between custom vs general hardware mean higher resistance and a better algorithm. This efficiency difference is the proper metric to use when comparing the quality of PoW algorithms.
Efficiency could mean absolute performance, performance per watt, or performance per dollar - they are all highly correlated. To process a single op on a CPU or GPU requires fetching and decoding an instruction, reading data from a register file, executing the instruction, and then writing the result back to a register file. This takes significant time and power. A single op implemented in an ASIC takes a handful of transistors and wires. This means every individual op takes negligible power, area, or time.
A hashing core is built by laying out the sequence of required ops. The hashing core can execute the required sequence of ops in much less time, and using less power or area, than doing the same sequence on a CPU or GPU. A bitcoin ASIC consists of a number of identical hashing cores and some minimal off-chip communication.
Unfortunately, popular coins such as Litecoin only use a scratchpad size between 32kb and kb for their PoW mining algorithm. This scratch pad is small enough to trivially fit on an ASIC next to the math core. The implementation of the math core would be very similar to SHA, with similar efficiency gains.
Each individual hashing core would have similar efficiency to an individual SHA core, so the overall design will have the same efficiency gains. X16R requires the multiple hashing cores to interact through a simple sequencing state machine. Each individual core will have similar efficiency gains and the sequencing logic will take minimal power, area, or time.
It has been upgraded to enable new algorithms that sequence the hashes in different orders.

In some situations, you can tell what portion of a network is running a certain model of mining rig depending on the nonce patterns guessed by the machines. Unfortunately, the E3 will become obsolete in the next few months, said Minehan and Carter, alluding to a recent report from mining pool 2Miners. Minehan and Carter say they fear a more powerful ASIC miner will replace the E3, creating a tech cycle that iPhone users are quite familiar with: planned obsolescence.
This fear becomes even more pressing given the size of the Ethereum network, said Starkware product manager Louis Guthmann. A compromise between the two camps was also given screen time on the call. Tl;dr As of now, nothing has been decided. Core developers on the call said they feel the community is fairly anti-ProgPoW.
Without this support, a change cannot be implemented even if perceived as a net benefit to the network. As the call closed, DiFrancesco pointed out that both parties have begun talking past each other, though there does seem to be agreement on one thing: nobody wants a contentious chain split. Read more about. Programmatic Proof-of-Work is nothing more than an extension of the Ethereum algorithm Ethash. The upgrade is meant to help graphics cards become more competitive against ASICs.
This way, miners can fight back against centralisation on the blockchain. Why is the Ethereum ProgPoW important? Since Ethereum was designed as a decentralised network, miners could use their GPUs to validate transactions and add new blocks to the chain. But when tech companies started producing ASICs which are more powerful than graphics cards and consume less energy , making profits using GPUs became a lot harder. The new equipment left GPU miners substantially out of pocket.
Many of them, in fact, are still struggling to recover their initial investment. This situation is leading to a loss of interest in maintaining network operations for Ethereum. Miners are moving to other blockchains where they have higher chances of getting rewards.
The domination of ASICs leads to a concentration of power in the hands of a limited number of users who own the right equipment. Decentralisation is therefore at risk. That would be enough to manipulate the entire blockchain. Instead, it brings some balance back to the equation by making them less effective than GPUs. The principle behind this extension is quite simple. The algorithm uses all components of GPUs to their full extent while changing the problem in mining regularly.
An unnecessary diversion from the Proof-of-Stake move? The crypto community is split between people who see ASICs as a threat to decentralisation and those who have the resources to invest in expensive equipment to gain higher rewards. This is why Ethereum developers have been planning a switch to Proof-of-Stake for almost four years.
