Exploring a Role of Blockchain Smart Contracts in Enterprise Engineering

摘要

Blockchain (BC) is a technology that introduces a decentralized, replicated, autonomous and secure databases. Smart contract (SC) is a transaction embedded to blockchain that contains executable code and its own internal storage, offering immutable execution and record keeping. Enterprise Engineering (EE) examines all aspects of organizations from business processes, informational and technical resources, to organizational structure. Therefore, blockchain and smart contracts have been subject of interest concerning the discipline of Enterprise Engineering (EE) and how they can be used together. In this paper, principles for creating smart contracts from DEMO models are described and a software architecture of an IT system based on EE integrating smart contracts is proposed. Finally, a proof-of-concept implementation of a smart contract of a mortgage process using a DEMO methodology was developed, to demonstrate the feasibility of the proposed concepts.
