The electronic contract itself is a kind of electronic data, which has security flaws such as easy tampering and deletion, which is not conducive to the long-term development of the service. In order to ensure the legal validity of electronic documents and electronic contracts signed by users on the electronic contract platform, the entire process of signing electronic contracts needs to be documented.

In the "Legal Chain" application implemented based on blockchain certification technology, the platform will archive the key links of electronic contract signing, and distribute and store key information and data into the entire blockchain. , thereby realizing the entire process of electronic contract storage.

Taking a closer look at its implementation principles, blockchain uses machine algorithms to solve the problem of consistency and reliability of multi-party transaction records through in-depth use of cryptographic algorithms, specially designed data structures and multi-party authentication algorithms. Storage and anti-tampering issues are naturally closely related to electronic data storage.

First of all, electronic contract signing records are stored in a shared ledger maintained by multiple parties. They cannot be tampered with, cannot be repudiated, and of course will not be lost.

Secondly, the electronic contract text and electronic contract elements are encrypted and stored, including the participants of the electronic contract. Only participants can decrypt and view the data to protect the privacy of the contracting parties.

Thirdly, the machine strictly executes according to the predefined rules (smart contract) and no longer relies solely on an agreement with a third party to guarantee it. The blockchain-based KYC service automatically checks and verifies the validity and identity of the certificate, ensuring that the identity of the participants is valid and authentic while ensuring privacy.

Currently, all electronic contracts signed on our electronic contract platform use blockchain technology to realize the distributed storage of digital fingerprints of electronic documents, further strengthening the legal validity of the electronic contracts on the platform.
