Blockchain architecture, originally designed for Bitcoin, has revolutionized finance through decentralized transactions and secured data management. It has been utilized to maintain private citizen records, allowing data owners to grant access via the blockchain for direct communication. Despite its potential, this technology remains relatively unexplored by both citizens and the public sector. By carrying out a thorough literature review, this article aims to shed light on this field. The research focus encompasses two key elements: (1) analyzing blockchain dimensions and (2) exploring its transformative impact on the public sector. The methodology involves an extensive meta-analysis of existing research on blockchain’s analytical aspects and its role in reshaping public administration. Additionally, a questionnaire is administered to Information Technologies (IT) experts in public services, comparing their perceptions with established scientific studies. The research’s core findings address various analysis dimensions, including regulatory risks, data management challenges, privacy concerns, and technological limitations. On the transformation front, organizations adopting blockchain technology anticipate enhanced networked services, fortified data security, operational efficiency, informed decision-making, and novel public services. The potential of blockchain to drive innovative services and safeguard data is widely acknowledged, yet organizations with blockchain are cautiously optimistic about its practical implications compared to those without.
