The dagger-Hashimoto algorithms can now be used to mine Ethereum and Ethereum classic. It was more memory-intensive and connected to Scrypt. Ethash is a more complex algorithm.

Graphic cards can be used by miners to mine Ethereum. Mega-hashes (MH/s), a unit for measuring the Ethash hash rate, is measured in mega-hashes.

Ethash is a Proof of Work algorithm that is exclusively designed for Ethereum (ETH) and is used only for mining. The primary reason for developing the Ethash hashing function was to support ASIC machines. The memory-intensive Ethash algorithms can only be mined using a GPU, and are resistant to ASIC technology.
