  SHA-256 is a cryptographic hash function used in blockchain technology to secure transactions. It takes an input, such as transaction data, and produces a fixed-size output of 256 bits. This output, known as the hash value, is unique to the input data. In the context of blockchain, each transaction is hashed using SHA-256, and the resulting hash value is stored in the blockchain. This hash value acts as a digital signature for the transaction, ensuring its authenticity and integrity. Any attempt to modify the transaction data will result in a different hash value, alerting the network to the tampering attempt. SHA-256 is widely regarded as a secure and reliable cryptographic algorithm, providing a strong layer of protection for blockchain transactions.
