Towards a graphical DSL for tracing supplychains on blockchain

Nowadays, supply chain tracing notarization is among the most used non-financial blockchain applications. However, creating a blockchain based system for the management of a supply chain remains a complex task. In this paper, we propose a graphical domain specific language (DLS) and a tool allowing the supply chain domain expert to easily represent the supply chain he needs to trace. The graphical representation of the supply chain is then translated in automatic way in a set of solidity smart contracts implementing it. A small intervention of a programmer is required to customize and finalize such smart contracts.The obtained semi-automatic process of smart contract generation will boost the blockchain usage for supply chain traceability
