To generate fresh crypto coins, you need to mine them. Crypto mining occurs through the Proof of Work (PoW) mechanism for many cryptocurrencies and blockchains. Ethash is a Proof of Work algorithm that facilitates mining on the Ethereum blockchain.
Ethash is a proof-of-work algorithm used for mining Ethereum and other ETH-based cryptos. Ethereum, Ethereum Classic and many other cryptocurrencies use it on their network. It is a modified version of the Dagger-Hashimoto algorithm. The unique features of this algorithm make it ASIC resistant and effectively verifiable.
However, Ethash is not a cryptographic hash function by itself. It is a variant of SHA3 hash called Keccak-256.
Let’s understand how Proof of Work runs on a blockchain. It will help you understand better before we dive in on how Ethash works.
A blockchain’ Proof of Work algorithm takes data from a block header as its input and uses the cryptographic hashing method to yield a fixed-length output. You can hash different variants of the input data by using a new set of numbers each time you submit data into the process.
Unlike the Dagger-Hashimoto version, Ethash kicks it up a notch by eliminating computing costs. This algorithm uses a vast data set that is regularly produced and gradually expands over time. However, the total programme size is small enough to fit in the VRAM of an old-school GPU.
The hash value produced in this process must be less than a certain threshold. This limit is called difficulty. The Ethereum network lowers or raises the difficulty level to manage the block mining pace.
Suppose the rate at which miners can find blocks are high. In such a scenario, Ethash will raise its difficulty. Alternatively, when the miners find it difficult to mine blocks, Ethash will lower the difficulty and more valid hashes will be available.
As a miner on Ethereum, you can get numerous benefits from Ethash. They are:
Learning about Ethash gives you the basic knowledge of how crypto mining algorithm works. You can use this knowledge to mine other cryptocurrencies like Etho Protocol (ETHO), Metaverse Entropy (ETP), MOAC (MOAC) and many more.
