Blockchain Governance for Trustworthy Digital Societies: From Smart Contracts to Decentralized Public Services

Abstract

Blockchain technology has matured from a cryptocurrency-only substrate into a general-purpose infrastructure capable of underpinning the governance of digital societies. By coupling cryptographically verifiable state with self-executing smart contracts and decentralized consensus, blockchains offer an alternative architecture for public services in which the rules of interaction are encoded, observable, and resistant to unilateral revision. This paper develops an integrative framework that situates blockchain governance at the intersection of computer science, public administration, and institutional economics. We synthesize the most recent literature (2016–2026) on smart-contract design, decentralized autonomous organizations, and government-led blockchain deployments to articulate a multi-layered governance architecture comprising infrastructure, consensus, smart-contract, governance, and public-service layers. We then analyze how each layer contributes to the seven trust dimensions—transparency, immutability, auditability, decentralization, privacy, resilience, and accountability—that we argue are jointly necessary for trustworthy digital societies. Using a structured cross-domain mapping of more than 170 documented deployments across digital identity, electronic voting, land registry, health records, welfare disbursement, taxation, and educational credentials, we identify the conditions under which decentralized public services improve service-delivery outcomes, the conditions under which they entrench new risks, and the design choices that mediate the difference. The analysis demonstrates that public-sector blockchain success depends less on technological maturity than on the alignment between on-chain mechanics and off-chain institutional capacity. We conclude with a research agenda that prioritizes governance interoperability, privacy-preserving auditability, and the legal recognition of code-based public obligations.
