-   Ethash was Ethereum's proof-of-work mining algorithm.

 [Ethash](https://github.com/ethereum/wiki/wiki/Ethash) is a modified version of the [Dagger-Hashimoto](/developers/docs/consensus-mechanisms/pow/mining-algorithms/dagger-hashimoto) algorithm. Ethash proof-of-work is [memory hard](https://wikipedia.org/wiki/Memory-hard_function), which was thought to make the algorithm ASIC resistant. Ethash ASICs were eventually developed but GPU mining was still a viable option until proof-of-work was switched off. Ethash is still used to mine other coins on other non-Ethereum proof-of-work networks.
