Research on the electronic contract processing method of blockchain

Glossary

Term definitionBlockchain is a decentralized distributed ledger technology that uses cryptographic methods to link data blocks together to ensure data security and transparency. Smart contract is an automatically executed contract stored on the blockchain, whose terms are written in code and automatically executed when specific conditions are met. Electronic contract is a contract generated, transmitted, stored and managed in electronic form, with the same legal effect as traditional paper contracts. Enterprise private key is the private key used by the enterprise to sign electronic contracts to ensure the authenticity and non-repudiation of the signature. Enterprise certificate is a digital certificate issued by a trusted institution, containing enterprise information and public key, used to verify the identity of the enterprise and the validity of the electronic signature. User private key is the private key used by the user to sign electronic contracts to ensure the authenticity and non-repudiation of the signature. User certificate is a digital certificate issued by a trusted institution, containing user information and public key, used to verify the identity of the user and the validity of the electronic signature. Hash value is an algorithm that converts data of arbitrary length into a fixed-length string, used to verify data integrity. CA institution certificate authority, responsible for issuing and managing digital certificates, ensuring the authenticity and reliability of digital certificates. Zhixin Chain is a blockchain platform that provides electronic contract signing and management services. Short answer question

How is the initial business electronic contract generated?

The initial business electronic contract is generated by the electronic contract processing device based on the business request sent by the enterprise server and the contract template in the blockchain smart contract. Specifically, the device extracts the key fields in the business request and fills them into the corresponding contract template.

What is the role of the enterprise certificate?

The enterprise certificate is issued by a trusted institution (CA institution) and contains enterprise information and public keys. Its role is to verify the identity of the enterprise and the validity of the electronic signature. The electronic contract processing device can use the public key in the enterprise certificate to verify whether the enterprise's signature on the electronic contract is authentic and valid.

What is the difference between a user's private key and a user certificate?

The user's private key is the private key used by the user to sign the electronic contract, while the user certificate is a digital certificate issued by the CA institution, which contains user information and the public key corresponding to the private key. The private key is used to generate an electronic signature, and the certificate is used to verify the user's identity and the validity of the signature.

Why is it necessary to compare the hash values ​​of electronic contracts?

The purpose of comparing the hash values ​​of electronic contracts is to verify the integrity of the electronic contract and ensure that the content of the contract has not been tampered with during the signing process.

What are the advantages of blockchain in electronic contract processing?

The decentralized, tamper-proof and transparent characteristics of blockchain can improve the security and credibility of electronic contracts, reduce transaction costs, and improve transaction efficiency.

What role does the Zhixin Chain platform play in electronic contract processing?

The Zhixin Chain platform is a blockchain platform that provides electronic contract signing and management services. Enterprises and users can complete identity authentication, certificate application, contract template definition, electronic contract signing and storage on the platform.

How do enterprises use the Zhixin Chain platform to sign electronic contracts?

Enterprises need to complete identity authentication and certificate application on the Zhixin Chain platform first, and then define the contract template and add it to the blockchain smart contract. After the user initiates a business request, the enterprise can use the private key to sign the generated initial electronic contract and upload the signed contract to the blockchain.

How do users verify the authenticity of the electronic contract?

Users can verify the authenticity of the electronic contract by viewing the hash value, enterprise certificate, and timestamp of the electronic contract. At the same time, users can also query the signing record and status of the electronic contract on the Zhixin Chain platform.

How to store and manage the electronic contract after it is signed?

After the electronic contract is signed, it will be stored on the blockchain and sent to enterprises and users by email. The tamper-proof nature of blockchain can ensure the long-term validity of electronic contracts and facilitate subsequent review and management.

How does the method proposed in this invention ensure the data reliability of network information?

This invention verifies the identity by using enterprise certificates and user certificates to ensure the authenticity and reliability of the identities of both parties signing the electronic contract. At the same time, blockchain technology is used to store and manage electronic contracts to ensure the integrity and tamper-proof nature of the contract content, thereby improving the data reliability of network information and avoiding the situation where information is stolen and interests are damaged.
