The mining algorithm dictates how transactions are verified and added to the blockchain, and it is central to the consensus mechanism that ensures the security and integrity of the cryptocurrency network. Bitcoin, for example, uses the SHA-256 algorithm.","\u003Cp>A mining algorithm is like a puzzle that miners need to solve to validate transactions and add new blocks to a blockchain.
