The advent of blockchain technology has inspired a new type of information exchange infrastructure on a peer-to-peer model that makes possible the emergence of a set of use cases in sectors where improved efficiency, reliability, security, and costs around transparency are sought. Blockchain adoption offers innovative opportunities for the public sector and can improve interactions with citizens and businesses. This trend is fueled by technological changes that are altering the daily environment of citizens and private businesses, and influencing their expectations for public service delivery. Developments indicating examples of change related to the trend include the implementation of new citizen-centric policies and services improving the use of data in the public interest. However, the integration of blockchain technology faces many technical challenges related to interorganizational coordination, including interoperability, privacy, governance, and business process impacts. To overcome this problem, infrastructure is needed to guide the integration of blockchain into public services.
In this thesis, the limitations of blockchain integration in public services are addressed by proposing a reference architecture that identifies the requirements for the challenges faced. In a joint effort with Revenue Quebec, a proof of concept that uses different technologies was developed in combination with a smart contract that orchestrates the execution of a public service and the delegation of a private treatment in a blockchain-independent component while centering the interactions around the citizen. To evaluate the designed architecture, the ATAM method was used on the proof of concept by developing a prototype around the scenarios of the vehicle registration process between Revenu Québec and the Société d’Assurance Automobile du Québec.
