In October 2023, the Monetary Authority of Singapore completed the first live cross-currency transaction on Project Guardian, a decentralised financial infrastructure pilot connecting DBS, JPMorgan, and SBI Digital Asset Holdings. The transaction settled in seconds on a shared blockchain network, bypassing the correspondent banking system entirely. It was not a simulation. Real money moved between real institutions on infrastructure that did not exist five years earlier. The global blockchain market, valued at $31.18 billion in 2025 according to Fortune Business Insights, is increasingly driven by institutions building this kind of shared financial infrastructure rather than standalone applications.
What Decentralised Financial Infrastructure Means
Financial infrastructure is the plumbing of the financial system: the networks, protocols, and systems through which money moves, assets settle, and records are kept. Today’s infrastructure is centralised. SWIFT handles messaging. DTCC handles clearing and settlement for US securities. CLS Bank handles foreign exchange settlement. Each system is operated by a single entity that sets rules, charges fees, and controls access.
Decentralised financial infrastructure replaces single operators with shared networks. Instead of one entity maintaining the ledger, multiple participants maintain identical copies. Instead of one entity approving transactions, consensus among participants validates each entry. The infrastructure is a protocol, not a company.
This distinction matters for two reasons. First, shared infrastructure eliminates the reconciliation problem. When every participant reads from the same ledger, there is nothing to reconcile. Second, shared infrastructure reduces concentration risk. The failure of a centralised system (an outage at DTCC, a cyberattack on SWIFT) affects every participant simultaneously. A decentralised system continues operating as long as a sufficient number of nodes remain active.
83% of financial institutions are exploring or deploying blockchain solutions, according to Coinlaw. The shift toward decentralised infrastructure is not driven by ideology. It is driven by operational efficiency and risk reduction.
Payment Infrastructure: From Messaging to Settlement
The most advanced decentralised financial infrastructure is in payments. Traditional cross-border payment infrastructure separates messaging (SWIFT) from settlement (correspondent banks). A SWIFT message instructs banks to move money, but actual settlement depends on each bank in the chain completing its own internal processes. This separation creates delays, opacity, and cost.
Blockchain-based payment infrastructure combines messaging and settlement into a single transaction. When a payment is recorded on a blockchain, it is simultaneously a message (describing what should happen) and a settlement (executing the transfer). Blockchain-based cross-border payments now process approximately $3 trillion annually, growing at 45% per year, according to Coinlaw.
RippleNet demonstrates this architecture at institutional scale. Over 300 financial institutions use the network for cross-border settlement, with transactions completing in three to five seconds. The XRP Ledger acts as both messaging layer and settlement layer: a single transaction record serves as proof of payment, settlement confirmation, and audit trail.
The cross-border payments market itself is valued at $371.59 billion in 2025, per Fortune Business Insights, projected to reach $727.74 billion by 2034. The infrastructure supporting those payments is where the structural change is occurring.
Securities Infrastructure: Clearing and Settlement
Securities clearing and settlement is the next major infrastructure layer being rebuilt on decentralised systems. In the US equity market, a trade executed on Monday does not settle until Wednesday (T+1 as of May 2024, reduced from T+2). During that gap, the clearinghouse (DTCC) guarantees the trade, both parties post margin, and back-office teams reconcile records.
On a blockchain, trade and settlement can happen simultaneously. A tokenised security trade executes when the buyer’s payment token and the seller’s security token swap in a single atomic transaction. There is no settlement delay, no clearinghouse guarantee needed, and no reconciliation required. The trade is the settlement.
JPMorgan’s Onyx platform processes over $1 billion in daily repo trading volume using this model. Both counterparties see the same transaction record. Settlement failures, which cost the industry approximately $900 million annually on traditional infrastructure, are reduced by over 60% on Onyx.
The European Investment Bank, Goldman Sachs, and HSBC have all issued digital bonds on blockchain infrastructure. These bonds settle on the same day they are issued, compared to the standard five-day settlement cycle for traditional bond issuance. The Blockchain-as-a-Service segment, which accounts for 51.72% of blockchain market revenue, provides the middleware that connects these issuance platforms to existing custodial and fund administration systems.
Identity and Compliance Infrastructure
Know-your-customer (KYC) verification is another infrastructure layer ripe for decentralisation. Today, every financial institution performs its own KYC checks on every customer. A person who opens accounts at three banks completes essentially the same identity verification three times. The global cost of KYC compliance is estimated at $6 billion annually.
Decentralised identity infrastructure allows a customer verified by one institution to share that verification with others through a blockchain-based attestation. The customer controls their own identity data and grants access to specific attributes (name, date of birth, accredited investor status) without revealing everything to every institution.
The Ethereum Attestation Service (EAS), launched in 2023, provides on-chain identity attestations that any institution can verify. Polygon ID uses zero-knowledge proofs to allow verification without data exposure: a user can prove they are over 18 without revealing their actual birth date. These systems are being adopted by fintech companies for customer onboarding and by institutional platforms for regulatory compliance.
Singapore’s Project Guardian includes an identity component that tests portable KYC across participating institutions. If successful, a customer verified by DBS could open an account at JPMorgan’s Singapore branch without repeating the entire verification process. The time savings for customers and cost savings for institutions are significant.
The Interoperability Challenge
The biggest obstacle to decentralised financial infrastructure is fragmentation. A bank running trade finance on R3’s Corda cannot easily transact with a counterpart using Hyperledger Fabric. A tokenised bond on Ethereum cannot be settled against a payment on Solana without a bridge (a protocol that transfers value between blockchains).
Bridges have been one of the most attacked components in blockchain infrastructure. The Wormhole bridge hack ($320 million, 2022) and the Ronin bridge hack ($625 million, 2022) demonstrated that connecting blockchains introduces security vulnerabilities that individual chains do not have.
SWIFT’s blockchain interoperability initiative, launched in late 2023, takes a different approach. Rather than building bridges between public blockchains, SWIFT is testing how its existing messaging infrastructure can coordinate transactions across private blockchain networks. The concept is that SWIFT becomes a meta-layer: a network of networks that routes transactions to the appropriate blockchain just as it currently routes messages to the appropriate bank.
If this model works, it would solve the fragmentation problem without requiring all institutions to adopt the same blockchain. Each bank could use its preferred platform while SWIFT handles cross-chain coordination. This is pragmatic but it maintains SWIFT as a centralised coordinator, which partially undermines the decentralisation principle.
What the Infrastructure Layer Looks Like by 2030
The trajectory suggests a hybrid architecture. Public blockchains (Ethereum, Solana) will handle tokenised assets and stablecoin payments. Private blockchains (Corda, Hyperledger, custom platforms) will handle institutional settlement and compliance-sensitive transactions. Central bank digital currencies will provide government-backed settlement finality. Interoperability protocols will connect these networks.
North America holds 43.80% of the global blockchain market, driven by the concentration of financial institutions, technology vendors, and regulatory experimentation. The BFSI sector accounts for 23.52% of market revenue. Private blockchains represent 42.47% of deployments.
The financial infrastructure of 2030 will likely look nothing like the infrastructure of 2020. It will also look nothing like the fully decentralised vision that early blockchain advocates imagined. It will be something in between: distributed enough to eliminate reconciliation costs and single points of failure, but governed enough to satisfy regulators and institutional risk management requirements. The institutions investing now are betting that building on this hybrid infrastructure will be cheaper and more resilient than maintaining the legacy systems it replaces.
