Ethash is a proof-of-work algorithm that is used in the Ethereum blockchain. It is designed to be memory-intensive, making it ASIC-resistant and favoring GPU mining instead.
Ethash is unique in that it requires a significant amount of memory to solve the cryptographic puzzles needed to mine new blocks on the Ethereum network. This memory-hard characteristic helps to prevent the centralization of mining power by making it more difficult and expensive for specialized mining hardware to gain an advantage over traditional consumer GPUs.
By using Ethash, Ethereum aims to create a more decentralized and accessible mining ecosystem. This is in contrast to other proof-of-work algorithms that can be dominated by large mining farms with specialized equipment.
Overall, Ethash plays a crucial role in maintaining the security and integrity of the Ethereum network by ensuring a fair distribution of mining power among participants.
