The Development of Smart Contracts for Heterogeneous Blockchains

The advanced development of blockchain technologies at present is to have external applications that interact with the native blockchain. A smart contract allows us to insert business logic which can add transactions and share them with multiple parties. This paper discusses the development process of a smart contract platform that aims to generate smart contracts for heterogeneous blockchain technologies. We start the process of creating a blueprint design, a datalogical stereotype that employs the ontology design from a Resources-Event-Agent (REA) perspective (McCarthy in The Accounting Review, LVII(3) (1982) [1]). With the modeling approach we are using in this paper, Unified Modeling Language (UML) and Object Constraint Language (OCL), we implement the workflow and algorithm in a supply chain demo sample [2].
