Cold-chain logistics needs decisions that are fast in operation and defensible at audit. This article presents a compact, evidence-centric workflow for service-level agreements (SLAs). SLA clauses are encoded as smart- contract rules on a permissioned blockchain with Byzantine fault-tolerant consensus (Hyperledger Fabric).
A reference architecture of such workflow has been presented and built with AWS cloud. It links signed IoT readings to small on-chain records while the raw data stay off-chain. The system has been tested with Hyperledger Caliper on three cold-chain scenarios and results indicate that the proposed architecture is effective for fast, reproducible, and auditable SLA enforcement in the cold chain logistics.
