Problems solved by technology

However, the existing electronic contract signing methods inevitably require the participation of at least one presumed trustworthy subject, such as the CA center maintaining digital certificates, or the intervention of a notary office based on a specific public-trusted identity. The CA center is technically reliable, but the reliable use must use the Ukey of the hardware medium, resulting in a serious lack of convenience, and the intervention of the notary office can solve the objective and credible identity problem of the electronic contract platform in legal terms. However, this can only be done entirely out of moral trust in the notary office, and cannot achieve reliable technical guarantees; in practice, solutions that are both convenient to use and technically reliable are very rare

Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] Such as figure 1 As shown, an electronic document signing method based on block chain and smart contract, it adopts business platform server CS, multiple block chain node servers TS and multiple block chain smart contract script servers JS, wherein, business platform server CS is used to accept user access and provide data interaction. CS connects and communicates with each block chain node server TS, and each TS communicates with the corresponding JS. The databases of each TS maintain data synchronization. The contract script server JS is a pre-set script execution code server deployed on the network. As a smart contract script on the blockchain, it can accept input in a predetermined format and complete the calculation output after receiving qualified input. The steps of the method include:

[0058] S1. Initialization steps:

[0059] S1.1. U...

Abstract

The invention provides an electronic document signing method based on a block chain and an intelligent contract. A service platform server CS, a plurality of block chain node servers TS and a plurality of block chain intelligent contract script servers JSs are adopted, wherein the service platform server CS is used for accepting the user access and providing data interaction, the CS communicates with the block chain node servers TS, each TS communicates with the corresponding JS, the databases of the JS keep data synchronization. The electronic document signing method is proposed based on the technical application of the block chain, and the problem of ensuring the electronic contract signing reliability from the technical aspect is solved without depending on a specific credible main body by means of the decentration idea of the block chain and in combination with the distributed account book and the intelligent contract mechanism.

Description

technical field [0001] The invention relates to the technical field of smart contracts, in particular to an electronic document signing method based on blockchain and smart contracts. Background technique [0002] At present, with the continuous development of e-commerce, traditional paper contracts are being replaced by electronic contracts. However, the existing electronic contract signing methods inevitably require the participation of at least one presumed trustworthy subject, such as the CA center maintaining digital certificates, or the intervention of a notary office based on a specific public-trusted identity. The CA center is technically reliable, but the reliable use must use the Ukey of the hardware medium, resulting in a serious lack of convenience, and the intervention of the notary office can solve the objective and credible identity problem of the electronic contract platform in legal terms. However, this can only be done entirely out of moral trust in the no...
