基于区块链技术的全省不动产登记数据汇交可信校验模型探讨

Discussion on the Provincial Real Estate Registration Data Collection and Delivery Credibility Verification Model Based on Blockchain Technology

摘要: 浙江省不动产登记运用现有的数据汇交方式，存在省市县三级数据一致性和安全性的问题。针对此问题，本文提出以“协作链”的方式引入区块链技术，创建不动产登记数据可信校验汇交模型，将不动产登记汇交关键数据通过生成唯一校验码上链和广播节点存储，形成不可篡改、可查、可用的分布式服务，保证省市县三级各节点数据高效同步、加密存储，实现不动产数据精准核验。

Abstract: Existing real estate registration data collection and delivery methods in Zhejiang Province have the problem of inconsistency and security at the provincial, municipal and county levels. To solve this problem, this paper proposes to introduce blockchain technology in the form of a “collaborative chain”, and creates a trusted verification remittance model for real estate registration data, the key data of real estate registration is stored in the blockchain and broadcast node by generating a unique check code, form a blockchain distributed service that cannot be tampered with, checked and available, ensure efficient synchronization and encrypted storage of data at all nodes at the provincial, municipal and county levels, and realize accurate verification of real estate data.
