Blockchain in Supply Chains: Trust Beyond the Hype

For those not steeped in technology, blockchain sounds abstract - part philosophy, part database, part network, part bookkeeping tool.

When it comes to supply chains, it all boils down to something very practical: trust.

The same properties that make blockchain useful in finance - immutability, decentralisation and consensus - have a significant relevance in supply chains.

Whether verifying where a product came from, confirming payment for shipments or preventing counterfeits, blockchain’s potential stretches across the global flow of goods.

Transparency from source to shelf

Blockchain keeps a record - permanent and tamper-proof - of whatever it’s asked to log.

In supply chains, that can include the provenance of raw materials, the handover points between factories and distributors, or whether goods meet certifications for ethical sourcing or sustainable farming.

A blockchain record means regulators, businesses and end-consumers can follow a product’s entire journey. It removes any doubt about origin, transit or ownership.

Every step becomes traceable. As the article puts it: blockchain is a “digital ledger” that records data across thousands of computers, rather than one central server. Once something is added to this ledger, it cannot be changed without agreement from the entire network.

In a supply chain context, that kind of audit trail provides real-time transparency that manual systems and spreadsheets simply cannot match. 

It also removes the need for intermediaries. The article notes that blockchain allows direct transactions between parties, bypassing brokers. That applies neatly to logistics, where suppliers, manufacturers and freight carriers often do not fully trust each other.

A shared blockchain platform lets them verify payments, shipments and certifications independently.

Barriers standing in the way

Still, blockchain is not yet the default for supply chains. The technology’s theoretical advantages are still wrestling with real-world obstacles.

As the article highlights, the issues are threefold: complexity, scalability and interoperability.

Wesley Crook, Chief Executive of blockchain engineering firm FP Block, says: “Developers often spend months rewriting code for different blockchains, systems buckle under real-world demand and projects are locked into a single chain that may not meet their needs over time.”

That fragmentation is especially problematic for global supply chains.

Different parts of a supply network often run on entirely separate systems - whether that’s SAP, Oracle or a custom local ERP. They need to exchange data, but often can’t. This mirrors the challenge banks face in moving money between incompatible ledgers.

According to Wesley, “more than US$2.8bn has been lost through bridge exploits,” referring to the tools used to link different blockchains.

“This highlights the fragility of current interoperability solutions. Instead of unlocking growth, poor design has exposed projects to massive security risks,” he says.

These technical failures matter, because supply chains generate vast volumes of data - from Internet of Things (IoT) sensors, shipping manifests, barcodes and invoices. If blockchain can’t scale to handle this load, its role will remain niche.

Competitive pressure is mounting

Despite the hurdles, momentum is building. The global banking cooperative Swift - used by more than 11,500 financial institutions - is working with Bank of America, Citigroup and NatWest to build its own blockchain infrastructure.

The new ledger will “record, sequence and validate transactions and enforce rules through smart contracts,” Swift says.

The move is designed to make “instant, always-on cross-border transactions possible at unprecedented scale.” It also mirrors why supply chains are showing interest - competitive pressure.

Much like Swift faces disruption from stablecoins, digital currencies pegged to fiat currencies, traditional supply chains face scrutiny from consumers, regulators and ESG auditors. These stakeholders demand faster, more transparent and verifiable data.

Those that can provide it, using blockchain, stand to gain a clear edge. Being able to verify product origins, ethical practices and arrival times without waiting on emails, spreadsheets or third-party assurances has business value.

Wesley believes strong engineering is what will finally unlock blockchain’s promise. His company’s platform, KOLME, allows applications to run on their own blockchains, but still interact with networks like Ethereum or Solana. This sidesteps scalability issues while enabling cross-chain interoperability.

“Too many projects fail because they were built on shaky foundations,” he says. “We apply mature DevOps and DevSecOps practices, rigorous code audits, and compliance-minded architecture to ensure projects are reliable, scalable and future-proof.”

The result, he argues, is that blockchain is on track to become “the backbone of trust and value exchange.” But that can only happen if companies shift from pilot schemes to serious infrastructure investment.

“We believe interoperability will be the key to unlocking its mainstream role,” Wesley says. “Once enterprises and developers can build applications that work seamlessly across ecosystems, blockchain will shift from experiments and pilots to critical infrastructure in the global economy.”

In other words, for blockchain to transform supply chains, it must first learn to speak the many languages those supply chains already use.

Once it does, it can deliver the transparency, traceability and trust the sector has long been missing.
