Electronic Contract Ledger System Based on Blockchain Technology

Abstract

The rapid development of the information Internet has promoted the development of electronic contracts, but user identities have been stolen and electronic contracts are easily tampered with. Seriously affected the fairness and security of online electronic transactions. For the main body of the transaction, how to confirm that the data identity of the transaction body has not been misused and the transaction electronic contract has not been tampered is the key problem which needs to be solved first. This paper designs the electronic contract platform by combining user identity authentication, encrypted transmission of electronic contracts and blockchain ledger storage. Ensure user identity uniqueness, contract transmission data integrity and non-tampering, and traceability of the signing process, thereby achieving security and fairness.
