Real-world blockchain use cases: what worked and what didn't

Supply chains, identity, healthcare and more: the projects that delivered, the ones that were quietly shut down, and why.

The short answer

Blockchains have proved most useful where several parties who don't fully trust each other need a shared record that no single one controls, and where money or tokens move on it, which is why payments, stablecoins and tokenized assets are the clearest successes. Many corporate projects outside finance struggled: Maersk and IBM shut down the TradeLens shipping platform in early 2023, and the Australian stock exchange wrote off about A$250 million on a blockchain settlement system in 2022. Some narrower uses, like food traceability at Walmart, did reach production.

When does a blockchain actually help?

A blockchain is a slow, expensive database with one superpower: many parties can share it without trusting any single operator. That helps only if:

Several organizations need to write to the same record,
They don't want any one of them (or a vendor) in control,
They can't easily agree on a trusted third party instead, and
The data going in is trustworthy in the first place. A blockchain faithfully records a false label typed in at the warehouse.

The US National Institute of Standards and Technology put it bluntly in its 2018 overview: blockchain "is not magical; it will not solve all problems". If one company runs the system anyway, an ordinary database is usually cheaper and faster. See what is a blockchain?

Supply chain

Worked, narrowly: Walmart food tracing. Using a Hyperledger Fabric system built with IBM, Walmart said tracing the origin of a package of mangoes fell from about seven days to 2.2 seconds. In September 2018 it asked its leafy-greens suppliers to join. The win came largely from suppliers digitizing records in one shared format.
Shut down: TradeLens. Maersk and IBM's global shipping platform was announced as closing on November 29, 2022, and went offline by the end of the first quarter of 2023. Maersk said it hadn't reached commercial viability, because "full global industry collaboration" hadn't been achieved: rival shipping lines didn't want to join a platform run by a competitor.
Also closed: bank-backed trade-finance networks we.trade (2022) and Marco Polo (2023) ran out of money after their backers stopped funding them.

Finance and markets

Worked: payments and stablecoins. Dollar stablecoins move hundreds of billions of dollars of value on public blockchains. See stablecoins and remittances.
Growing: tokenized assets. Funds holding Treasury bills and other traditional assets are now issued as tokens on public and private blockchains.
Failed: ASX CHESS replacement. The Australian Securities Exchange abandoned its blockchain-based replacement for its share settlement system in November 2022 after an independent review, writing off about A$245–255 million before tax.

Identity

The idea: you hold credentials (a diploma, a license, proof of age) in your own wallet, signed by the issuer, and share only what's needed. The W3C published a Decentralized Identifiers (DID) standard in 2022, and several governments are rolling out digital ID wallets. Most of these keep personal data off any blockchain, and many don't use one at all; where a blockchain is used it typically stores only public keys or revocation lists. Putting personal data on an unchangeable public ledger clashes with privacy laws such as the EU's right to erasure.

Healthcare

Health records are the classic example in pitch decks and among the least successful in practice: records are sensitive, must be correctable, and hospitals already have regulated systems. The more practical work has been in the drug supply chain. In the US, the MediLedger project, started in 2017 by drug makers, distributors and pharmacies, built a shared network to verify drug product identifiers under the Drug Supply Chain Security Act. Even there, much of the industry's compliance runs on conventional systems.

Gaming and digital ownership

Games where items are NFTs let players resell what they own. The 2021 play-to-earn boom showed the demand and the danger: see NFT gaming and Axie Infinity. Name systems such as ENS are a smaller but durable use of NFTs.

The pattern

Tended to work	Tended to struggle
Moving value: payments, stablecoins, tokenized funds	Industry consortiums led by one big company
Narrow, well-defined records with a strong sponsor	Projects where the blockchain was a solution looking for a problem
Open networks anyone can join	Data that must stay private or be corrected

Frequently asked questions

What are real-world uses of blockchain?

The clearest are payments and stablecoins, tokenized funds, and some supply-chain traceability such as Walmart's food tracing. Many corporate projects in shipping, trade finance and stock settlement were shut down.

Why did TradeLens fail?

Maersk said it never reached commercial viability because the shipping industry didn't collaborate fully. Competitors were reluctant to join a platform run by a rival. It shut down by the end of the first quarter of 2023.

Is blockchain used in healthcare?

Mostly in limited ways, such as verifying drug products in the supply chain. Putting patient records on a blockchain has largely not caught on, for privacy and practical reasons.

Does a digital ID need a blockchain?

No. Most digital identity wallets work without one. Where a blockchain is used, it usually holds only public keys or revocation lists, not personal data.

Is enterprise blockchain dead?

Not entirely, but many high-profile consortium projects closed between 2022 and 2023. Activity has shifted toward tokenized assets and payments on shared networks.
