SHA-256 (Secure Hash Algorithm 256-bit) is a hashing function used in the Proof of Work (PoW) consensus mechanism to validate transactions and create new blocks in a blockchain. The most famous SHA-256 coin is Bitcoin, but other coins, such as Bitcoin Cash and Bitcoin SV, also use the SHA-256 algorithm.","\u003Cp>SHA-256 coins are cryptocurrencies that rely on the SHA-256 algorithm for their mining and transaction verification processes. SHA-256 is a type of cryptographic hash function, which takes input data (like transaction details) and generates a fixed-length string of characters (called a hash). This hash is a unique identifier for that data and is used to secure blocks in the blockchain.\u003C\u002Fp>\u003Cp>For example, when Bitcoin miners solve complex mathematical puzzles to add a new block to the blockchain, they use SHA-256 to generate a hash that meets specific criteria. The first miner to find the correct hash gets to add the block and is rewarded with Bitcoin. Other SHA-256 coins use similar methods for mining and transaction validation.\u003C\u002Fp>","\u003Cp>SHA-256 coins operate using the Proof of Work (PoW) consensus mechanism, where miners use computational power to solve cryptographic puzzles based on the SHA-256 algorithm.
