AI Technical Summary
The existing electronic guarantee system has problems with omissions and information leaks during the review process, resulting in low accuracy and threatening the interests of relevant parties.
A two-layer blockchain technology is used to hash and encode key information of engineering activities. Combined with the dependencies between preceding and subsequent activities of the critical path chain (CPM), a multi-link tree structure is formed. The blockchain is expanded by hash encoding and its matching degree to ensure information privacy and authenticity. At the same time, smart contracts are deployed to automatically trigger contract terms.
While ensuring information privacy, it maximizes the efficiency and credibility of information interaction, solves the problem of low speed in establishing and accessing blockchain databases, and achieves transparency, traceability and immutability of information.
