SHA-256 is a cryptographic hash function used to secure and verify transaction data on Proof-of-Work blockchains like Bitcoin, ensuring the integrity and continuity of the blockchain.

Understanding SHA-256

SHA-256 stands for Secure Hashing Algorithm-256, a key part of the Bitcoin network’s foundation. This algorithm plays a critical role in verifying transactions and maintaining the overall security of the blockchain. By generating unique digital signatures, SHA-256 ensures the integrity of transaction data.

How SHA-256 Functions

SHA-256’s Role Beyond Bitcoin

While SHA-256 is synonymous with Bitcoin, its application extends to other areas. It’s a modified version of the SHA-2 algorithm, originally developed by the NSA. SHA-256 is also utilized in various operating systems, enhancing their security protocols.

Why SHA-256 Matters

SHA-256 is not just a technical term; it’s a cornerstone of blockchain security. It provides a robust shield against data tampering, making it indispensable for secure digital transactions.
