Supply chain traceability is the most successful enterprise blockchain use case — by actual deployments, not by whitepaper count. Walmart uses it. Maersk used it (TradeLens). The pharmaceutical industry is being regulated into it (DSCSA).

But the platform you choose determines whether your traceability system ships in 6 weeks or 6 months. Whether it costs $16K/year or $450K/year. Whether your logistics partners can deploy their nodes without hiring a blockchain consultant.

Here's the platform comparison that supply chain operators actually need.

Supply chains are a textbook blockchain use case: multiple independent organizations, each updating the status of goods as they move, with no single party trusted by everyone to maintain the system of record.

The challenge with most supply chain blockchain implementations is queryability. You can verify that a record exists, but answering "show me all shipments currently in customs that have been there for more than 48 hours" typically requires an external indexing layer.

This tutorial shows you how to build a complete supply chain traceability system where the blockchain state is directly queryable with SQL — no separate database, no sync lag, no extra infrastructure.
