Blockchain for Governance and Security: A High-Assurance Multi-Layer Framework for National-Scale Public Administration | IJCT Volume 12 – Issue 6 | IJCT-V12I6P59
Government systems across the world continue to experience structural issues such as data manipulation, lack of auditability, opaque administrative workflows, and rising cyber threats. Although blockchain technology offers decentralized trust, immutability, and transparent validation mechanisms, existing governance-oriented implementations remain fragmented and insufficient for nationwide deployment. To address these limitations, this study introduces the High-Assurance Multi-Layer Blockchain Governance Framework (HMBGF)—a comprehensive architecture that integrates decentralized identity management, a hybrid Delegated Proof-of-Stake and Byzantine Fault Tolerant consensus model, tamper-resistant audit chains, and policy-driven smart contracts.
A series of large-scale simulations using realistic governance datasets demonstrate that the proposed framework significantly enhances operational efficiency and security. The system reduces validation latency by more than 41%, increases tamper-detection accuracy to near-perfect levels, and maintains throughput exceeding 2600 transactions per second under intensive loads. Additionally, a formal security bound is derived to quantify adversarial success probability under validator corruption, confirming the architecture’s resilience. The results indicate that HMBGF is well-suited for real-world governance applications such as electronic voting, property registration, public fund oversight, welfare distribution, and inter-agency coordination. This work contributes a novel, secure, and scalable foundation for next-generation digital governance.

Conclusion
This study introduces a comprehensive, secure, and scalable blockchain-based governance architecture capable of addressing the structural vulnerabilities of centralized public administrative systems. Through its multi-layer design—incorporating decentralized identity, hybrid consensus, and tamper-resistant audit chains—HMBGF provides an integrated solution for transparent and accountable governance.
The system demonstrated substantial improvements in throughput, latency, and tamper detection during extensive simulation and adversarial testing. The theoretical guarantees further substantiate its robustness against validator compromise and external threats. Collectively, these results highlight its potential for deployment across high-stakes governance domains such as elections, property management, welfare verification, and financial oversight.
While limitations exist in scalability, infrastructure dependency, privacy risks, and off-chain vulnerabilities, the architecture provides a solid foundation upon which future innovations—including quantum-safe cryptography, AI-driven automation, and interoperable governance networks—can be built.
HMBGF represents a promising advancement toward building trustworthy, efficient, and secure public governance systems that align with emerging digital government paradigms worldwide.
