Achieving Service Accountability through Blockchain and Digital Identity

This paper proposes a platform for achieving accountability across distributed business processes involving heterogeneous entities that need to establish various types of agreements in a standard way. The devised solution integrates blockchain and digital identity technologies in order to exploit the guarantees about the authenticity of the involved entities’ identities, coming from authoritative providers (e.g. public), and the trustiness ensured by the decentralized consensus and reliability of blockchain transactions.
