Based on the results of the feasibility simulation experiment, actually apply the visa contract algorithm to the power grid engineering business visa business, feedback optimization, adapt to various dynamic changes, adopt a contract incentive mechanism, optimize existing contracts, and propose new contracts; S4. Based on the blockchain visa process, conduct multi-dimensional traceability evaluation based on actual use cases, including execution time, cost, number of uses, participants, effect feedback, etc.

[0006] The invention patent application with the application publication date of 2021.02.19 and application publication number CN 112380549A discloses "a method for managing statistical data of power grid engineering project investment based on blockchain". By establishing a data management framework for power grid investment engineering projects based on blockchain, it can achieve decentralized data sharing and data security storage in a distributed system where distributed nodes / departments do not need to fully trust each other through the use of data certificates, data encryption, workload authentication, distributed consensus and smart contracts. It provides an effective and feasible solution to the problems of high cost and low efficiency of centralized data platforms, and provides a basis for promoting lean data management of power grid engineering projects and improving the standardization of project process management.

[0007] Although the above technical solution focuses on decentralization and data confidentiality requirements, it requires strong support from high-performance computer systems and is not suitable for operation and use by ordinary technicians, which brings certain inconveniences to its specific implementation and use. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide an App-based power grid project feasibility study design process management system.
