中新网海口6月18日电 (尹建军 李思雨)不动产证书是重要的财产权属凭证，广泛应用于房产交易、抵押融资、政务办理等场景。海南省自然资源和规划厅18日介绍，海南依托区块链技术深化不动产登记数字化改革，实现电子证照“链上存证、指尖亮证、安全可信、全域可用”，大幅提升群众办事便利度和产权交易安全性。
Hainan, which launched the blockchain application pilot for real estate registration in 2023, continues to promote the deep integration of technological innovation and government services. In 2025, Hainan will coordinate the promotion of blockchain on-chain data with the construction of "Internet + Real Estate Registration", relying on the province's unified government blockchain base, and will fully complete the on-chain integration of real estate registration electronic licenses for the whole province (excluding Sansha City) in 2026. The relevant blockchain query, license display, and verification functions were officially launched in May this year.
At present, Hainan has built a trusted database of blockchain real estate electronic licenses that is unified throughout the province and dynamically updated, and has successfully connected to the national main chain of the Ministry of Natural Resources, realizing provincial data retention, national aggregation, and national mutual recognition. All real estate licenses in the province are stored on the chain, relying on the tamper-proof and traceable technical characteristics of the blockchain, preventing data tampering and certificate forgery risks from the source.
In the past, when people handled transfer, mortgage, financing, water, electricity, and gas transfer and other businesses, they had to repeatedly carry and present paper certificates. It was more time-consuming, laborious, and costly for owners in other places and overseas owners. Now, they only need to log in to the Hainan Provincial Real Estate Registration Comprehensive Service Platform and display and verify licenses online anytime and anywhere through their mobile terminals, without paper materials and without running back and forth. Electronic licenses have the same legal effect as paper licenses, which simplifies the business process and standardizes transaction verification.
The landing application of blockchain technology this time is an important measure for Hainan to promote "reducing certificates and benefiting the people", deepening the construction of digital government, and helping the construction of a smart Hainan and a free trade port. A relevant负责人 of the Hainan Provincial Department of Natural Resources and Planning said that the next step will be to expand the application scenarios of blockchain real estate electronic licenses, covering high-frequency fields such as financial mortgages, financial leasing, and linkage transfer of water, electricity, and gas.
At the same time, actively connect with the national real estate registration "cross-provincial handling" reform requirements, relying on the open advantages of the free trade port, explore new models of blockchain empowerment for cross-provincial handling, continue to promote data trusted sharing and business interconnection, and make every effort to achieve "online handling, video handling, one-time handling, and cross-provincial handling" of real estate registration.
