What is Ethash

Ethash is the proof-of-work function in Ethereum-based blockchain currencies.

It uses Keccak, a hash function eventually standardized to SHA-3. These two are different, and should not be confused. From version 1.0 Ethash has been designed to be ASIC-resistant via memory-hardness (harder to implement in special ASIC chips) and easily verifiable.

General information of Ethash

The general route that the algorithm takes is as follows:

  1. There exists a seed which can be computed for each block by scanning through the block headers up until that point.
  2. From the seed, one can compute a 16 MB pseudorandom cache. Light clients store the cache.
  3. From the cache, we can generate a 1 GB dataset, with the property that each item in the dataset depends on only a small number of items from the cache. Full clients and miners store the dataset. The dataset grows linearly with time.
  4. Mining involves grabbing random slices of the dataset and hashing them together. Verification can be done with low memory by using the cache to regenerate the specific pieces of the dataset that you need, so you only need to store the cache.

The large dataset is updated once every 30000 blocks, so the vast majority of a miner’s effort will be reading the dataset, not making changes to it.
