A Blockchain and Smart Contract Framework for Transparent Administration
Abstract
A blockchain-and-smart-contracts architecture, which is suggested in the present research, can make public administration become more transparent, efficient, and trustworthy. The old-fashioned integrated systems of administration have the disadvantage of tampering with data, slow auditing and lack of trust of the population. To achieve these problems we develop a multi-layered solution that consists of: a user-facing application layer; a governance-rule automation layer driven by smart contracts; a Proof-of-Authority consensus layer that is fast with permissioned agreement; and a storage layer that integrates off-chain storage with immutable distributed ledger. To support the performance assessment, we establish mathematical models that are used to validate transactions, latency, cost, and transparency. The framework runs on a decentralized Hyperledger Fabric network with permissioned validator nodes and is tested on a real-world data sample of approximately 8, 000 government procurement records. Our experiments demonstrate significant improvements over conventional ERP-based systems: 2.8x increase in throughput, 65 percent decrease in average latency, an increase in a transparency index by 38 percent, 22 percent better data integrity, as much as 35 percent better fraud-detection effectiveness, and reduced operating cost per transaction by 39 percent. Through the introduction of read-only nodes, tamper-proof record and real-time audits, the suggested infrastructure enhances accountability and exemplifies how the blockchain-enabled governance can make the processes of the public sector more rapid, more secure, and people-focused.
