Design And Implementation Of Notary Collaboration Platform Based On Consortium Block Chain

With the development of global economic integration and regional economic integration,economic cooperation projects spanning multiple regions,provinces and even countries are blooming everywhere.While the scope of economic activities has long since broken the limits of geography,the corresponding development of notarial legal services still lags behind.Due to the provisions of the Notary Public Law on practice areas,notary publics work separately from each other in terms of notary system informationization,and there are problems such as poor coverage of off-site business,lack of effective means of communication,continued need for centralized institutions,and low willingness to share data among various notary publics,so that notary clients are unable to handle notary business quickly and effectively.In response to the above-mentioned problems in the notary field,this paper applies the consortium chain technology to the notary system and combines blockchain smart contracts,consensus algorithms,multi-level data encryption and other technologies to design and implement a notary federation platform for notary institutions built by consortium chain technology for cross-regional notary business processing.By combining the traceable and non-tamperable features of the consortium chain,the system provides two functions of interface data sharing and collaborative service opening to solve the problems arising from the non-uniform security technology standards and non-adaptation of historical interface data among notary institutions.In terms of performance,this paper significantly improves the response speed of the system under the condition of ensuring the system data security and trustworthiness through the on-chain and off-chain trusted collaboration mechanism.At the same time,this paper proposes a dynamic incentive mechanism based on smart contract,based on evolutionary game theory,introducing reputation level and value level,modeling and simulating the behavior of notary institutions,and designing a smart contract with dynamic incentive on top of the simulation results,which improves the willingness to share among notary institutions through scientific incentive.
