Blockchain in Supply Chain
Definition
Blockchain in supply chain uses a shared, tamper-evident digital ledger so multiple trading partners can record and verify transactions — provenance, custody, certifications — without trusting a single central party.
In Practice
Each participant writes events (harvested, shipped, inspected, received) to a distributed ledger that no single party can quietly alter. That immutability makes blockchain attractive where partners do not fully trust each other's records: provenance of food, conflict minerals, luxury goods authentication, and trade documentation.
Practitioners should be clear-eyed: blockchain solves record integrity, not data quality — a false entry recorded immutably is still false, so it works best paired with IoT sensors or third-party verification at the point of capture. Several high-profile consortium projects have shut down where simpler shared databases sufficed.
Example: IBM Food Trust lets a grocer trace a package of mangoes back to the farm in about two seconds, versus nearly seven days using paper trails — dramatically narrowing the scope of a contamination investigation.
