An Application of Ethereum smart contracts and IoT to logistics

摘要: Over the last few years, interest has emerged in blockchain, a decentralized ledger technology (DLT) created for use cryptocurrencies, but with great potential to be used other application domains. One of them is supply chain management, tracking and tracing, whichare key processes logistics industry, made difficult due lack standards or trust between actors, miscommunication, fraud, bureaucratic delays, among issues. In order overcome some these challenges, solution presented this article proposes blockchain system Ethereum smart contracts technology, tracing products through storage valuabledata trustworthy system. The technical here implements methods automated tracking, certification authentication, integrates communication IoT devices, which play role monitoring automating clearance processes. We validate our approach by developing an that highlights benefits technologies applied logistics, ultimatelygiving insight into capabilities, qualities, also limitations like can have.
