Ethash is a proof-of-work algorithm primarily used by Ethereum to secure its network and validate transactions. It is designed to be memory-intensive, meaning it requires significant amounts of RAM to operate efficiently. This helps to reduce the advantages that specialized hardware, like ASIC miners, have over traditional GPUs.The process begins when miners compete to solve complex mathematical puzzles. The first miner to find the solution gets to add a new block to the blockchain and is rewarded with Ether, the network’s currency. Ethash’s memory-heavy design ensures that mining remains accessible to individuals using consumer-grade hardware.Ethash also includes a feature called “DAG” (Directed Acyclic Graph), which changes periodically. This characteristic ensures that the mining process remains challenging and continually adapts to the network’s needs. As a result, Ethash aims to promote decentralization by making it harder for any single entity to dominate the mining process.
