The most established real-world blockchain use cases are stablecoin payments, tokenised funds and commodities, decentralised finance, supply-chain traceability and publicly verifiable custody. The common thread is a record that several parties who do not fully trust each other need to share and check, rather than one company keeping a private database.
Which blockchain use cases are already in use?
Each example below draws on one or more of the core benefits of blockchain: a shared tamper-evident record, 24/7 settlement, public verifiability or programmable assets.
| Use case | Example | What the blockchain adds | Caveat |
|---|---|---|---|
| Stablecoin payments | US dollar stablecoins such as USDT moving between wallets | Transfers at any hour, settled on-chain | Depends on the issuer's reserves and on regulation |
| Tokenised money-market fund | BlackRock's BUIDL, launched on Ethereum in March 2024, holding cash, US Treasury bills and repurchase agreements | Shares that move 24/7 between pre-approved investors, with dividends paid as new tokens | Open to qualified investors only |
| Tokenised gold | Tether Gold (XAUT): each token represents one troy fine ounce on a London Good Delivery bar | Fractional gold exposure that can be transferred at any time | Relies on the issuer's custody of the bars |
| Tokenised stocks and ETFs | Ondo Global Markets tokens that track US stocks and ETFs | Economic exposure held on-chain | No shareholder voting rights; restricted for US persons |
| Supply-chain traceability | Walmart's Hyperledger Fabric system for tracing food | One shared record across suppliers and the retailer | Only as accurate as the data suppliers enter |
| Decentralised finance (DeFi) | Exchanges and lending markets run by smart contracts | Open access and building blocks that combine | Smart contract, oracle and bridge risk |
| Verifiable custody | Custodians publishing wallet addresses so balances can be checked | Anyone can confirm that assets exist | Shows assets held, not what is owed to customers |
How is blockchain used in finance?
Finance has the most production use, because the product is itself a digital record of ownership. Stablecoins let dollars move between wallets at any hour. In the US, the GENIUS Act signed on 18 July 2025 created a federal framework for payment stablecoins that requires 100% reserve backing with liquid assets such as US dollars or short-term Treasuries, plus monthly disclosure of reserves.
Tokenised funds such as BUIDL show large asset managers issuing fund shares directly on public chains. Tokenised commodities such as tokenised gold let investors hold fractions of a physical asset. Our guide to real-world asset tokenisation explains how these structures work, and Ondo tokenised stocks explained covers on-chain exposure to US equities.
How is blockchain used outside finance?
Supply chains are the best-documented example. Walmart and IBM built a food-traceability system on Hyperledger Fabric; in the pilot, tracing mangoes back to their source fell from 7 days to 2.2 seconds, and Walmart later traced more than 25 products from 5 suppliers. Other uses include digital identity, where wallets hold verifiable credentials, and registries of ownership or provenance.
NIST lists a need for "full provenance of digital assets" and for a "decentralized naming service or ordered registry" among the signs that a blockchain may fit. Where one organisation controls the whole process, a database usually does the job better.
Which blockchain projects have failed, and why?
Not every project survives. Maersk and IBM's TradeLens shipping platform, announced in 2018, was shut down after Maersk said in November 2022 that it had not reached the commercial viability needed to continue, citing a lack of full global industry collaboration. The lesson repeats across sectors: a shared ledger only helps if the participants agree to share it. NIST also warns that many organisations adopt blockchain out of fear of missing out rather than need.
How do smart contracts make these use cases possible?
Most financial use cases run on smart contracts: token contracts that track balances, exchange contracts that swap assets and multi-signature wallets that need several approvals before moving funds. The weak point is the link to the real world. A token is only as good as the gold, Treasury bill or stock behind it, and the issuer's records of that backing.
Tokenised assets in Wealtii's funds: Wealtii's Balanced fund holds tokenised gold (XAUT), a tokenised silver ETF (SLVon) and a tokenised S&P 500 ETF (SPYon) alongside TRON, Bitcoin (BTCB), XRP and BNB. Tokenised stocks and ETFs give economic exposure only, with no shareholder voting rights, and funds that contain them may not be available in all jurisdictions, including the United States.
Frequently Asked Questions
What are the real-world use cases of blockchain?
The most established are stablecoin payments, tokenised funds, gold and stocks, decentralised finance, supply-chain traceability and verifiable custody. Each involves several parties sharing a record they all need to trust.
How is blockchain used in finance?
Blockchains carry stablecoins, tokenised money-market funds such as BlackRock's BUIDL, tokenised gold and stocks, and decentralised exchanges and lending markets. They allow 24/7 transfers and on-chain settlement, but the tokens still depend on their issuers and on regulation.
Is blockchain used in supply chains?
Yes. Walmart's food-traceability system, built with IBM on Hyperledger Fabric, cut the time to trace mangoes from 7 days to 2.2 seconds in a pilot. Other projects, such as Maersk and IBM's TradeLens, closed because not enough of the industry joined.
What is asset tokenisation?
Asset tokenisation means issuing blockchain tokens that represent a claim on a real-world asset, such as a fund share, a gold bar or a stock. Tokens can trade in small units and move 24/7, but their value depends on the issuer actually holding the asset.
