#PowellRemarks Supply chain transparency is one of the most practical and powerful applications of blockchain. Blockchains like VeChain, OriginTrail, IBM Food Trust (on Hyperledger Fabric), and Ambrosus are leading in this field. VeChain uses NFC chips, RFID, and IoT sensors to record the journey of products from production to the hands of consumers, ensuring that data cannot be altered. OriginTrail focuses on data compatibility and standardizing information across chains. IBM Food Trust collaborates with major corporations like Walmart to trace food origins in seconds instead of days. These systems help businesses combat counterfeiting, increase consumer trust, and improve operational efficiency. In the era of globalization, blockchain is not just a financial technology, but also a powerful tool for managing supply chains transparently and decentralizing.
