Blockchain-based secure estate property management system (BlockeState).

Estate property bonds are official legal documents used to prove a person's ownership of a property. These documents represent a guarantee of the legal rights of property owners. Challenges related to record keeping, transfer of ownership, and verification of ownership pose major problems. These issues also negatively affect the rights and interests of real estate owners and government agencies in the real estate sector. One solution to these challenges is using blockchain technology. This technolog provides a decentralized and immutable ledger to facilitate the protection of real estate transactions and the tracking of assets. In this paper, a property records registration and management system based on blockchain technology called "BlockEstate" is designed and implemented. A system leverages smart contracts (written in Solidity), produces an irreversible and non-repeatable hash value using the keccak256 function (making it a unique and reliable indicator of the contract) and deployed on the Binance Smart Chain. The BlockEstate system was applied on about 50 real estate records for testing purpose. The experimental results showed its capability to achieve fast access within time frame not exceed two seconds. It was also achieved easy management on estate property bond through digital, secure, eliminating for physical documents, signatures and seals. These results indicate the potential for BlockEstate to be used as an innovative and future-proof tool in real estate property management. [ABSTRACT FROM AUTHOR]
