BlockConfess: Towards an Architecture for Blockchain Constraints and Forensics

Although Blockchain is still an emerging technology it has the potential to serve as a general purpose information technology platform. Already, smart contract / chaincode platforms, such as Ethereum and Hyperledger Fabric, provide support for the execution of arbitrary computations. However, the suitability of these platforms for specifying and enforcing data and service usage constraints (e.g., usage policies, regulatory obligations, societal norms) and providing guarantees with respect to conformance has yet to be determined. In order to address this gap, in this position paper we argue that symbolic artificial intelligence techniques in the form of semantic technology based policy languages and business process conformance tools and techniques, can together be used to provide guarantees with respect to the behaviour of autonomous smart contract / chaincode applications.
