Blockchain-Based Tokenization and Management of Land Documents: A Decentralized Approach for Secure Ownership and Transfer

Abstract

Blockchain technology is transforming real estate with its transparency and security. Its decentralized, immutable ledger ensures all transaction records are tamper-proof and visible. This paper addresses a critical flaw in the traditional market: fragmented systems that often overlook approvals from inspectors and lenders. By leveraging the Ethereum blockchain and its smart contracts, Block realty automates agreements, eliminating intermediaries and enhancing efficiency. The paper utilizes the ERC-721 standard to tokenize real estate assets, converting properties into unique digital tokens. This fundamentally changes asset management, enhancing market liquidity and global accessibility. A key feature is a comprehensive three-step approval process, ensuring all stakeholders-buyers, lenders, inspectors, and sellers are actively engaged. Each party's approval is immutably recorded on the blockchain, creating a verifiable chain of custody that boosts transaction integrity. The use of Non-Fungible Tokens (NFTs) also facilitates fractional ownership, allowing multiple investors to jointly own a single property. This democratizes real estate investment by lowering the barrier to entry. For data management and cost optimization, Blockrealty integrates the Inter Planetary File System (IPFS), a decentralized storage protocol for securely housing property images and metadata. Additionally, seamless Metamask integration provides a user-friendly interface. Looking ahead, upcoming Ethereum advancements like the Pectra upgrade are poised to enhance Ethereum's scalability and efficiency, further strengthening the foundation for platforms like Blockrealty by enabling them to handle transactions more effectively and reliably.
