Drawings
FIG. 1 is a schematic diagram of a blockchain-based electronic contract signing method of the present invention.
Detailed Description
The invention is described in detail below with reference to the drawings and the specific embodiments.
As shown in fig. 1, the electronic contract signing method based on block chain of the present invention comprises the following steps: and S1, signing the electronic contract by the two contract signing parties through an electronic signing platform. And S2, the electronic signing platform respectively processes the data information of important links of the two signing parties in the signing process of the contract to obtain a plurality of certificate storage points. And S3, the electronic signing platform sends a plurality of certification deposit points to the certification deposit platform. S4, the certification platform stores a plurality of certification points and synchronizes the certification points to the judicial blockchain respectively. Through the steps, key information signed by the contract is encrypted and uplink, trusted storage is carried out on a third party node by using a block chain consensus mechanism, indiscriminate evidence-providing service and judicial service are provided for both electronic contract signing parties, and legal effectiveness of the electronic contract signing is ensured. The above steps are specifically described below.
For step S1, the two contract signing parties sign the electronic contract through the electronic signing platform.
The specific process of signing the electronic contract by the two contract signing parties through the electronic signing platform comprises the following steps: user registration, real name authentication, signing intention confirmation, CA certificate issuance, electronic contract signing, and the like.
And S2, the electronic signing platform respectively processes the data information of important links of the two signing parties of the contract in the signing process of the contract to obtain a plurality of certificate storage points.
In the application, the electronic signing platform integrates the certificate storage SDK, and the electronic signing platform respectively processes the data information of important links of the two contract signing parties in the contract signing process through the integrated certificate storage SDK to obtain a plurality of certificate storage points.
Here, the important links refer to user registration, real name authentication, signing intention confirmation, CA certificate issuing, and electronic contract signing of both contract signing parties in the contract signing process. The electronic signing platform respectively processes the data information in the links of user registration, real name authentication, signing intention confirmation, CA certificate issuing and electronic contract signing of the two contract signing parties in the contract signing process through the integrated certificate storage SDK to obtain a plurality of certificate storage points.
Specifically, the evidence storage SDK calculates evidence digital abstract, time stamp and digital signature of evidence storage content to obtain a plurality of evidence storage points, and determines evidence storage content, evidence storage time and evidence storage party.
Specifically, the data information contains basic information. The basic information includes: time information, location information, user information, and platform information. That is, in the important link described above, the basic information (time information, location information, user information, and platform information) is also authenticated together each time.
Further, the evidence storage SDK calculates an evidence digital abstract, marks a time stamp and digitally signs the evidence storage content to obtain an evidence storage point according to the data information of the system log.
For step S3, the electronic signing platform sends the plurality of certification deposit points to the certification deposit platform.
And for the step S4, the certification platform stores a plurality of certification points and synchronizes the certification points to the judicial blockchain respectively.
Specifically, the judicial blockchain comprises a plurality of nodes such as a court node, a judicial identification center node and a notarization department node, and the certification platform synchronizes the certification points to the judicial blockchain respectively and then performs certification curing on the court node, the judicial identification center node and the notarization department node through a distributed billing mechanism of the blockchain.
The above process is the uplink evidence-storing process of electronic contract signing, when one of the two parties of the contract signing needs evidence-storing evidence to conduct litigation proof, any one of the two parties of the contract signing submits a report generation request to the electronic signing platform, and the electronic signing platform generates a contract evidence-storing report after receiving the report generation request and returns to the submitting party of the report generation request. The chain of contract evidence forensics report may serve as the prover material for the submitting party. And submitting the received contract evidence chain evidence storage report to any one of a court node, a judicial identification center node and a notary node by a submitting party, and carrying out on-line comparison and confirmation on the contract evidence chain evidence storage report by any one of the court node, the judicial identification center node and the notary node for receiving the contract evidence chain evidence storage report so as to judge the authenticity of the contract evidence chain evidence storage report. Thereby saving the period of the proving process and greatly shortening the litigation time.
