High-Performance Decentralized Land Administration on Solana

Land administration is a critical function for ensuring ownership rights, resolving disputes, and enabling economic development. Conventional systems for managing land records often suffer from inefficiencies, centralization-related vulnerabilities, and recurring fraudulent practices like multiple property sales, falsified documents, and illegal changes in ownership. These issues are further exacerbated in developing countries, where digital infrastructure is limited, and manual processes dominate. While blockchain technologies like Ethereum have attempted to address these challenges through decentralization and smart contracts, their practical implementation is often hindered by high transaction (gas) fees, limited scalability, and network congestion. This paper presents a novel, decentralized land administration framework built on the Solana blockchain, which offers significant performance advantages due to its Proof of History (PoH) consensus mechanism and Sealevel parallel processing engine. Utilizing Solana’s rapid transaction processing and low- latency architecture, the platform delivers a reliable, efficient, and tamper-resistant solution for land record management. In addition to its blockchainbased core, the system leverages a modern technology stack comprising for an intuitive and responsive user interface, for executing backend logic and managing smart contract interactions, and Supabase for off-chain data storage with real-time database capabilities. This combination ensures efficient integration between components, delivering a seamless user experience while maintaining high system performance and reliability. The proposed system automates critical functions like property register, ownership confirmation, and document validation using smart contracts, thereby greatly decreasing reliance on intermediaries and reducing the risks linked to centralized data storage.. Experimental outcomes and practical validation confirm the platform’s effectiveness in significantly improving transparency, security, and operational efficiency over conventional land systems and previous blockchain-based solutions. This makes the solution highly suitable for integration into contemporary land governance models, particularly in regions that demand scalable and trustworthy digital infrastructure.
