Collection: SHA-256

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function widely used for data encryption and verification. It’s best known as the proof-of-work algorithm used in Bitcoin mining, where miners solve complex mathematical puzzles to validate transactions and secure the blockchain. SHA-256 generates a unique 256-bit output from any input, ensuring data integrity, as even a minor change in the input drastically alters the hash. Its robust security makes it resistant to collision and preimage attacks, and it plays a crucial role in securing decentralized networks like Bitcoin.
