Abstract

Accountability refers to the need of individuals or organizations to account for their activi- ties, accept responsibility, and disclose results in a transparent manner. Nowadays, the pervasivity of digital systems is making increasingly critical security, reliability, and trustworthiness of such services. When a service is delivered by involving different (eventually conflicting) parties, account- ability could be achieved by including in digital transactions a trusted third party (TTP). Blockchain decentralizes trust, thus avoiding to rely on a single TTP. However, to deal with accountability in concrete solutions, the issue of securely integrating digital identity and Blockchain should be solved. The paper describes the results of a three-year research project merging academic and industrial expertise, to design and implement a Blockchain-based platform for service accountability integrating eIDAS-compliant Public Digital Identity. The platform has been used in several real-life contexts made available by industrial project partners, which demonstrated the effectiveness and novelty of the solution.
