  Bitcoin employs the SHA-256 (Secure Hash Algorithm 256-bit) encryption algorithm to protect its transactions. SHA-256 is a cryptographic hash function that takes an input and produces a fixed-size output, which is a 256-bit (32-byte) hash value. This algorithm is designed to be secure and resistant to collisions, meaning it is highly unlikely for two different inputs to produce the same hash value. By using SHA-256, Bitcoin ensures the integrity and immutability of its transaction data.

  The encryption algorithm used by Bitcoin is SHA-256. It's like a digital fingerprint for each transaction. When a transaction is made, the transaction data is hashed using SHA-256, resulting in a unique hash value. This hash value is then included in the blockchain, making it virtually impossible to alter the transaction data without being detected. SHA-256 is widely used in the cryptocurrency industry due to its strong security properties.
