Gejun Le, Qifeng Gu, Qingshan Jiang, Weiyi Lin · 2020
Supply chain involves mutual independent and distrusted stakeholders and large of sensitive order data. Sharing data among stakeholders is a essential project because that improves efficiency for various workflow among stakeholders. This paper proposes TrustedChain, a blockchain-based data sharing scheme for supply chain, which has two advantages: (a) trusted: we present a trusted environment, Trusted Environment (TE), based on blockchain to allow mutually distrusted stakeholders manage data collaboratively. (b) secure: we provide a secure design that first stores order forms in Distributed Database (DDB) and then records URI in Contract Account (CA) of TE. In addition, Supply-Business Contract Management (SCM) manages all CA and Node Communication (NC) allows communication over the network. The security analysis and evaluation prove the effectiveness of TrustedChain.
