Problems solved by technology

This form will inevitably lead to cost, efficiency and data security issues. Once the third-party platform is attacked, or the centralized organization has fraud or data tampering, it will seriously affect the authenticity and security of the warehouse receipt.
[0003] On the other hand, data privacy protection is difficult in the verification process of traditional warehouse receipts. Many core data involve commercial secrets. Enterprises are worried about data leakage, which makes it difficult for enterprises to balance data transparency and privacy protection.
[0004] According to relevant research, in the bulk commodity industry, there is no good solution to the lack of trust in the transaction process, the difficulty of verifying the authenticity of cargo rights and warehouse receipts, and the difficulty of data privacy protection

Embodiment 1

[0037] Such as figure 1 with figure 2 As shown, a warehouse receipt verification method based on blockchain and zero-knowledge proof, the warehouse receipt verification method based on blockchain and zero-knowledge proof includes the following steps:

[0038] Step S1: Build a blockchain distributed storage database;

[0039] Construct a blockchain encrypted data distributed storage database for warehouse receipt verification, specifically using blockchain technology for distributed accounting, including steps such as endorsement, consensus, sorting, and accounting;

[0040] Step S2: Encrypt the owner's warehouse receipt information and upload it to the blockchain;

[0041] The data encryption specifically includes: adopting the SHA-512 encryption algorithm for data encryption.

[0042] The concrete steps of described SHA-512 encryption algorithm include:

[0043] Generate the salt value, combine the business json data with the salt value, and arrange them in ascending lex...

Abstract

The invention discloses a warehouse receipt verification method based on a block chain and zero knowledge proof. The warehouse receipt verification method comprises the following steps: constructing ablock chain distributed storage database; the warehouse receipt information of the cargo owner is subjected to data encryption and then is uploaded to the block chain; when a transaction occurs, zero-knowledge verification is carried out on warehouse receipt information through nodes of each party of the block chain; the authenticity of the warehouse receipt and the cargo information is proved according to a verification result; and the authenticity, accuracy and privacy of warehouse receipt information in the transaction market can be ensured.

Description

technical field [0001] The invention relates to the technical field of warehouse receipt verification, in particular to a warehouse receipt verification method based on blockchain and zero-knowledge proof. Background technique [0002] In the commodity industry, traditional warehouse receipts can only be issued unilaterally by the warehouse and can only be recorded and maintained by the warehouse. The issuance of electronic warehouse receipts needs to rely on large insurance companies, credit agencies, electronic certification agencies, supply chain service companies, electronic Business companies, spot and futures exchanges, arbitration institutions, quality inspection agencies and other multi-level institutions work together, and the trust between institutions at various levels depends on the reputation and scale of the third-party platform. This form will inevitably lead to problems of cost, efficiency and data security. Once the third-party platform is attacked, or the c...
