A bond can be issued as a token and settled against digital money on shared infrastructure. That does not make the issuer, the legal claim or the need for reliable settlement disappear. It changes how instructions, ownership records and payment can be coordinated. This concrete distinction is more useful than treating Web3 as a replacement for the financial system. In finance, the term covers several architectures: public blockchains, permissioned distributed ledgers, tokenised securities, stablecoins, wallets and decentralised protocols. They have different governance and trust assumptions. Tokenisation changes the representation and workflow Tokenisation represents an asset or claim as a programmable ledger entry. Transfers can carry rules, and applications can combine issuance, collateral movement and settlement instructions. The Bank for International Settlements describes this potential in its work on the next-generation monetary and financial system: tokenisation can integrate messaging, reconciliation and asset transfer rather than passing them through separate databases. The token is not automatically the asset. A tokenised bond still depends on an issuer’s obligations and applicable securities law. A tokenised deposit remains a claim on a bank. A token representing property or a fund interest needs an enforceable link between the ledger entry and the offchain right. Code can control transfer without creating that legal link by itself. Delivery-versus-payment can reduce coordination gaps Traditional securities processing separates trade execution from clearing and final settlement. Multiple institutions reconcile records and manage the risk that one side delivers before the other. A shared ledger can support delivery-versus-payment: transfer of the asset occurs if the corresponding payment occurs under the same coordinated process. That model is being tested, not merely proposed. The European Central Bank’s 2025 report on new technologies for wholesale central-bank-money settlement records work with 64 participants and almost €1.6 billion in real and mock transactions. The exercises included normal flows as well as error and failure scenarios. Faster coordination does not guarantee irreversible finality in law. Participants still need rules for mistakes, sanctions, insolvency, governance and operational outages. The settlement asset matters too: commercial-bank money, central-bank money and a privately issued stablecoin do not carry the same credit and redemption risk. Stablecoins offer a payment rail with issuer risk Stablecoins can move around the clock between compatible wallets and applications. They are used as quote assets, collateral and settlement instruments in crypto markets, and increasingly as an interface between onchain services and conventional payment systems. The apparent simplicity hides several layers. A holder relies on the reserve assets, custody arrangements, redemption promise, legal entity and liquidity of the specific token. Tokens with the same unit of account on different chains may be separate liabilities or bridged representations. The BIS 2026 Annual Economic Report highlights fragmentation and interoperability limits in permissionless systems as well as the monetary shortcomings of stablecoins. DeFi makes financial functions programmable Decentralised finance uses smart contracts to perform functions such as exchange, collateralised lending and derivatives. Users can interact through a wallet, while other applications can call the same contracts. This composability allows developers to build on existing liquidity and rules without a bilateral integration for every service. It also links failures. A lending position may depend on an oracle, a collateral token, a bridge and an automated market maker. A fault or governance change in one component can propagate through the others. The Financial Stability Board’s assessment of DeFi vulnerabilities finds that DeFi reproduces familiar functions and risks—including leverage, liquidity mismatch and interconnectedness—while adding operational dependencies. “Decentralised” should therefore be tested component by component. A protocol may have public transaction execution but a centrally hosted frontend, concentrated voting power, changeable contracts or a small group controlling emergency keys. The architecture in our DeFi explainer separates these layers. What changes for institutions Issuance: asset terms and transfer restrictions can be represented in programmable instruments. Operations: a shared record can reduce repeated messaging and reconciliation between participants. Settlement: cash and asset legs can be coordinated more closely, potentially reducing principal risk. Collateral: eligible assets can move and be monitored on a more continuous basis. Distribution: wallet-based access can widen technical reach, subject to identity, legal and suitability rules. Institutions do not need to choose between an unchanged legacy stack and anonymous public-chain finance. Permissioned ledgers, public networks and conventional databases can interoperate in hybrid designs. Each boundary introduces questions about identity, data confidentiality, governance and which record is authoritative. A framework for evaluating a Web3 finance claim Name the function: issuance, trading, lending, custody, payment or settlement. Identify the claim: what legal or economic right does the token represent, and against whom? Locate control: who runs validators, changes code, operates the interface and can stop or reverse activity? Trace dependencies: include keys, custodians, oracles, bridges, stablecoins and offchain data. Define finality: distinguish technical confirmation from legal settlement and redemption. Measure the improvement: compare cost, time, failure handling and capital use against the existing process. Blockchain is changing parts of financial infrastructure, but progress is clearest where a specific coordination problem is defined and tested. Tokenisation can compress workflows; it cannot substitute for a sound claim, trustworthy money or accountable governance. Editorial note: Reworked from the evidence up on September 3, 2026. Obsolete market forecasts were removed, and tokenisation, settlement, stablecoins and DeFi are now assessed as separate systems. This is educational material, not financial advice.
