Blockchain-Based Port Logistics Data Integrity Platform

In multi-party port logistics, data exchanged among terminal operators and logistics platforms is vulnerable to disputes when managed by a centralized system. Built on Hyperledger Fabric, this platform enables each stakeholder to independently record and verify logistics transactions across CFS/CY operations on a shared, tamper-proof ledger. Key differentiators: (1) equal, independent verification rights with no central authority; (2) ETRI-certified data confidentiality (TTAK.KO-10.1359); (3) production-ready with three registered software components and granted Korean patent (KR 10-2916863).
