example 1

[0056] This example is used for the signing of an existing electronic contract. The signing process includes the following steps:

[0057] After the user registers and authenticates successfully on the electronic contract platform, he uploads the existing electronic contract to the electronic contract platform, and the user applies to the CA for an event certificate and uses the certificate to sign the original electronic contract. Other relevant parties of the electronic contract sign the same electronic contract through the same steps. The electronic contract platform records each operation process information to the blockchain. When there is a dispute over the contract, the user submits the original electronic contract to the notary office, and the notary office notarizes the original electronic contract.

example 2

[0059] This example is used to sign an electronic contract generated using an online template. The signing process includes the following steps:

[0060] After the user registers and authenticates successfully on the platform, he selects a template from the contract template library, modifies the template information, fills in the specific contract content, and applies for a CA certificate to sign the electronic contract. Other relevant parties of the electronic contract sign the same electronic contract through the same steps. The electronic contract platform records the information of each operation process, including contract element information other than the template, to the blockchain. When there is a dispute over the contract, the user submits the original electronic contract generated to the notary office, and the notary office notarizes the original electronic contract.

Abstract

The invention discloses a block chain evidence-based electronic contract system signing method. The method comprises the following steps of: creating an electronic contract on an electronic contract platform by a user or uploading an existing electronic contract to the electronic contract platform, and signing the electronic contract by using an event certificate issued by a CA; recording information of each key point in a contract signing process of the user and event occurrence time points to a block chain evidence platform by the electronic contract platform; and extracting the information from a node of a block chain evidence consortium chain by a notary office, decrypting the information by using a secret key of the user, obtaining specific information of contract signing, and notarizing the contract of the user. According to the method, the signing of electronic contracts is more convenient, the time and costs of the users are saved; a block chain evidence system technically ensures that the electronic contracts cannot be tampered; and the process information of contract signing also can be recorded, so that the contract signing behaviors of the users can be restored.

Description

technical field [0001] The present invention relates to the field of electronic contracts, in particular to a method for signing an electronic contract system based on blockchain storage, and in particular to a system for electronic contract storage using blockchain. Background technique [0002] The electronic contract transfers the traditional contract signing process to the Internet. The traditional contract signing process requires both parties to sign the paper contract and then mail it. The whole process takes a long time and costs high. The certificate issued by the Certificate Authority signs the electronic contract and has the same legal effect. The current electronic contract platform proves that it will not tamper with the contract by acting as a neutral third party, but technically speaking, it is possible for the electronic contract platform to tamper with the content of the contract. Blockchain technology is very suitable for the storage of electronic contract...
