Abstract: In this paper, we present a solution to the problem of e-contract validation in a supply chain with chain contracting topology. In chain contracting, there are multiple bi-lateral contracts that are related, for example one original contract between two partners is modified by subsequent negotiations to form other bi-lateral contracts between other parties in the supply chain. We study how to validate these contracts and ensure appropriate relationship between these contracts. We first identify key technical requirements for such a solution and then present our models that address these requirements. The models are based on the concepts of commitment scheme and zero-knowledge proof. It can be implemented in a contract engine that supports both the contract formation and contract execution phases of the contract life cycle. Also proposed is a cryptographic scheme to facilitate the electronic transfer of payments.
