Problems solved by technology

[0004] 1. The offline contract signing process is complicated, and the cost of cooperation between the two parties is high
The connection between the business party and the customer needs to be carried out offline. When the contract is signed, it needs to go through multiple negotiations, which will consume a lot of labor costs and time costs.

Embodiment Construction

[0022] The purpose and effect of the present invention will become more obvious by describing the present invention in detail according to the accompanying drawings and specific embodiments.

[0023] Such as figure 1 , 2 As shown in and 3, a blockchain-based electronic contract deposit method includes the following steps:

[0024] Step 1: The contract signing initiator uploads the electronic contract:

[0025] In the electronic contract online signing system based on blockchain technology, the business party, as the contract signing initiator, can configure the corresponding electronic contract in the system, support Word, PDF and other file uploads, and the system records the contract initiator and contract information into the blockchain;

[0026] The contract initiator uses the personal private key and electronic signature to sign the contract. After signing the contract, the initiator designates the signatory of the contract, and the system sends the contract to the cli...

Abstract

The invention discloses a blockchain-based electronic contract evidence storage method, which comprises the following steps that: a contract initiator specifies a contract signer to upload a private key and initiates signing of a contract; according to the information of the joint signer, a signed contract notification message is sent to a contract receiver, and a certificate in the signing process of the to-be-signed party is generated; the contract receiver completes contract signing; it is determined that the joint signers complete signing, and when the plurality of signers complete signing, signed contracts are stored to the blockchain system; the block chain records the certificates in all the generated electronic contract data processes; two parties of the contract can upload a contract file, and contract content is stored in the block chain; according to the transaction hash value, the two parties can check and verify one stored contract content to judge whether the stored contract content is changed by the village or not. Through the steps, the whole process from signing to checking of the contract is recorded in the block chain system, and the electronic contract can not be tampered.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for depositing certificates of electronic contracts based on block chains. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data, information cannot be forged and tampered with, and transaction confirmation on the blockchain is shared by all nodes on the blockchain Completed, the consensus algorithm guarantees its consistency. A public ledger is maintained on the blockchain to store the balance of all users on the blockchain network. The public ledger is located at any node on the storage block to ensure that it cannot be forged and tamper. [0003] In the traditional paper contract signing process, there are basically the following two problems: [0004] 1. The offline contract signing process is complicated, and the cost of cooperation between the ...
