Problems solved by technology

With the rapid development of computer technology, traditional paper contracts are gradually replaced by electronic contracts. In traditional technology, the electronic contract is stamped by directly calling the interface for signing the electronic seal. This method has security risks. When the interface When maliciously attacked, it is easy to cause wrong signing of wrong electronic seal

Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0021] The electronic seal signing method based on blockchain smart contract provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The server 104 first obtains the contract information and the organization identification corresponding to the contract information, generates a smart contract according to the contract information and the organization identification, stores the electronic seal key in the smart contract, and then writes the smart cont...

Abstract

The present application relates to the field of block chain technology, and provides an electronic seal signing method, device, computer device and storage medium based on block chain intelligent contract. The method comprises the following steps: acquiring contract information and an organization identifier corresponding to the contract information, generating an intelligent contract according tothe contract information and the organization identifier, wherein the intelligent contract includes an electronic seal key; writing the intelligent contract into the block chain; receiving an electronic seal signing request sent by the terminal, and spreading the electronic seal signing request in the block chain, wherein the block chain is used for consensus on the electronic seal signing request; When the consensus is passed, the target electronic seal key is obtained, and when the target electronic seal key coincides with the electronic seal key in the intelligent contract, the intelligentcontract is executed to obtain the electronic contract with the signed electronic seal. The method of the present application is capable of preventing the electronic seal from being incorrectly signed.

Description

technical field [0001] This application relates to the technical field of blockchain, in particular to a method and device for signing electronic seals based on blockchain smart contracts. Background technique [0002] When two or more parties sign a contract, it is often necessary to affix a seal to the contract to ensure the authenticity and validity of the contract. With the rapid development of computer technology, traditional paper contracts are gradually replaced by electronic contracts. In traditional technology, the electronic contract is stamped by directly calling the interface for signing the electronic seal. This method has security risks. When the interface When maliciously attacked, it is easy to cause wrong signing of wrong electronic seal. Contents of the invention [0003] Based on this, it is necessary to address the above technical problems and provide a method and device for signing an electronic seal based on a blockchain smart contract that can preve...
