Scalable, Secure and Broad-Spectrum Enforcement of Contracts, Without Blockchains (1904.09940v1)

Abstract: This paper introduces a scalable and secure contract-enforcement mechanism, called Cop, which can be applied to a broad range of multi-agent systems including small and large systems, time-critical systems, and systems-of-systems. Cop enforces contracts (or protocols) via the existing Law- Governed Interaction (LGI) mechanism, coupled with a new protective layer that significantly enhances the dependability and security of such enforcement. Cop is arguably superior to the currently popular blockchain-based smart-contract mechanisms, due to its scalability, interoperability, and the breadth of the spectrum of its domain of applications.
