Supply Chain Blockchain: How It Works and Real Uses in 2025

When you hear supply chain blockchain, a digital ledger that records every step of a product’s journey from origin to customer. Also known as blockchain in logistics, it doesn’t just track shipments—it proves they happened, who touched them, and when. Unlike old paper logs or scattered databases, this system is shared, unchangeable, and visible to everyone who needs to see it.

That’s why major players like Walmart, Maersk, and Nestlé are using it. If a bag of coffee is traced back to a farm in Colombia, the blockchain tracking, the system that logs each handoff with timestamps and digital signatures. Also known as supply chain transparency, it lets buyers verify claims about fair pay, organic status, or carbon footprint. If a medicine gets lost in transit, the supply chain security, the protection against tampering, counterfeits, and unauthorized access built into the ledger. Also known as blockchain integrity, it flags any change that wasn’t approved. No more guessing. No more forged certificates. Just facts stored on a network that no single company controls.

It’s not magic. It needs sensors, scanners, and people who actually enter data correctly. But when it works, it stops fraud before it spreads. A shipment of tuna from Indonesia? You can see the boat ID, the catch date, the port it left, and the freezer temp at every stop. A pair of shoes made in Vietnam? You know if the factory paid workers fairly, not just what the label says. That’s the power of a shared truth.

What you’ll find below aren’t theory pieces. These are real reviews of tools, platforms, and projects that actually use this tech—some working well, others failing hard. You’ll see which DEXs tie into logistics tokens, which airdrops pretend to solve supply chain issues, and which exchanges quietly track goods on-chain. No fluff. Just what’s real, what’s broken, and what’s worth your time in 2025.
