Electronic contract chaining method based on block chain

Abstract

The invention discloses an electronic contract chaining method based on a block chain. The electronic contract chaining method comprises the following steps that two contract signers register block chain accounts respectively; a group of operation sub-accounts are respectively configured through block chain accounts of two parties of a contract, the operation sub-accounts comprise an entering person account and a decision maker account, and each operation sub-account has a public and private key pair; the method comprises the following steps: jointly entering a newly created contract through entering person accounts of both parties of the contract, respectively utilizing private keys of the two parties to carry out contract chaining operation signature, then carrying out signature authorization on respective contract chaining operation signatures through decision maker accounts of the two parties of the contract, and sending the contract to a block chain node and chaining; when the contract needs to be modified, the contract is modified through the logger accounts of the two parties of the contract, contract chaining operation signatures are carried out on the newly modified contract through the private keys of the two parties of the contract, and then the contract is sent to the block chain node and chained after signature authorization is carried out on the respective contract chaining operation signatures through the decision maker accounts of the two parties of the contract.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based electronic contract chaining method. Background technique [0002] A contract is an agreement between the parties or both parties to establish, modify, and terminate a civil relationship, which mainly includes paper contracts and electronic contracts. The signing of paper contracts requires processes such as printing, stamping, express delivery or manual delivery. Once there is any modification, these processes need to be repeated. The main defect is that the process is complicated, time-consuming and labor-intensive. Electronic contracts solve the problem of complex process of paper contracts, but electronic contracts are usually kept by the platform side, lack of third-party storage, prone to tampering, low transparency, and greater legal risks. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ...
