Research and Application of Archive Data Management System Based on Blockchain

Blockchain is an accounting technology that is jointly maintained by multiple parties, uses cryptography to ensure transmission and access security, and can achieve consistent data storage, hard to tamper with, and prevent repudiation. It is characterized by strong confidentiality, non tampering, and decentralization. Use blockchain HyperLedger technology to store archive data, extract the hash value of the original file and other key information and record it in the blockchain ledger, to ensure that the data can not be tampered with and the credibility of the stored data.
