The SHA256 algorithm generates a 256-bit hash value for the input data to ensure the consistency and integrity of the data. In blockchain, the main application of the  SHA256 algorithm is to validate block headers (including the hash value of the previous block, the transaction hash value of the current block, etc.) and create new blocks. By using the SHA256 algorithm, the blockchain system can achieve high security and tamper-resistant characteristics."}]}],"pr":"b5a7b27ff1d31046a988ecc2c07b749d2b913e59df60128aa0afdd5644a707fa"}
