The Real Direction of On‑Chain Finance: The Structural Divide Between J.P. Morgan’s Private Ledger and Citi’s Global Settlement Network
3-Point Summary
- Japan is redesigning its national financial infrastructure by moving equities, government bonds, and cross‑border payments on‑chain, centered on Citi’s Swift Digital Ledger–based settlement system now live in production.
- J.P. Morgan and Citi are taking fundamentally different on‑chain approaches: J.P. Morgan is building a private Besu‑aligned institutional ledger, while Citi is extending SWIFT’s global payment and settlement network directly onto blockchain.
- Despite different strategies, both systems rely on the EVM, signaling that global regulated finance — including Japan, Citi, J.P. Morgan, HSBC, and BlackRock — is converging on Ethereum‑based infrastructure for long‑term global settlement standardization.
Japan is entering a new phase of on‑chain finance, extending SWIFT‑based global settlement infrastructure onto blockchain for real‑time, risk‑minimized cross‑border payments.

Japan Redesigns Its On‑Chain Infrastructure for International Payments and Settlement
How Citi, J.P. Morgan, and the SWIFT Digital Ledger Connect
Japan has officially launched a national project to move core financial infrastructure—equities, government bonds, and cross‑border payments—on‑chain. At the center of this shift is the Swift Digital Ledger–based cross‑border payment infrastructure operated by Citi Bank in Japan, which is now live in production. This marks Japan’s transition beyond the experimental phase into the global settlement infrastructure expansion phase.
J.P. Morgan has built a proprietary private ledger that processes payments inside the institution and among selected participants through Onyx, JPM Coin, and Liink. Citi, by contrast, has chosen the Swift Digital Ledger model, which keeps SWIFT’s global messaging and payment network intact while extending only the settlement layer onto blockchain.
As a result, Japan’s on‑chain financial transition is clearly converging not on a Besu‑based internal execution layer, but on a strategy of expanding SWIFT‑centric global payment infrastructure. Japan is preserving SWIFT’s international payment, settlement, and messaging structure while using blockchain to achieve 24/7 real‑time settlement, minimized risk, and enhanced international accessibility.

1) Citi Bank Brings Tokenized Cross‑Border Payment Infrastructure to Japan
In Japan, Citi Bank has deployed a Swift Digital Ledger–based cross‑border payment infrastructure, keeping SWIFT messaging intact while extending the payment and settlement layer on‑chain. Through this, Japan has moved a global payment system that offers 24/7 real‑time cross‑border transfers and instant liquidity into full production.
2) J.P. Morgan — Onyx + JPM Coin + Liink (Proprietary Private Ledger)
J.P. Morgan has built a private‑ledger‑based payment network using Onyx, JPM Coin, and Liink to process payments inside the institution and among selected counterparties. This is a closed infrastructure designed for automated global payments and real‑time settlement, not to replace SWIFT’s global payment flows, but to create a parallel, independent payment network.
J.P. Morgan’s private ledger is technologically aligned with Besu‑based permissioned networks and is structured to support EVM compatibility, bridges, and asset movement with public Ethereum.
3) Citi — The Swift Digital Ledger Family (Global Payment Infrastructure Expansion)
Citi’s model is designed to extend the entire global payment and settlement infrastructure operated by SWIFT onto blockchain. SWIFT messaging (MT/MX) is preserved as‑is, while the payment and settlement layer is migrated to blockchain, enabling integrated processing of cross‑border payment authorization, settlement, and messaging.
Unlike Besu, which primarily serves as an internal execution layer, Citi’s approach expands the global settlement layer that connects 11,000 financial institutions worldwide onto blockchain.
4) The Common Foundation: EVM (Ethereum Virtual Machine)
J.P. Morgan’s private ledger stack (Quorum, Onyx, Besu) and Citi’s Swift Digital Ledger pursue different objectives, but they share the same technical foundation: the EVM (Ethereum Virtual Machine). This means that while global regulated finance has not directly adopted public Ethereum as its base, it has effectively chosen the Ethereum technology stack as its standard execution environment.
An EVM‑based architecture unifies smart contract logic, transaction formats, developer tooling, and security models. J.P. Morgan can maintain its private ledger while still enabling bridges, asset transfers, and interoperability with public Ethereum. Citi, meanwhile, gains technical flexibility to keep SWIFT’s global payment network intact while extending only the settlement layer on‑chain.
In practice, major global institutions—Japan, Citi, J.P. Morgan, HSBC, BlackRock, and others— are pursuing different strategies yet converging on the same EVM‑based technical foundation. This trajectory suggests that, over the long term, global payment infrastructure may be standardized on top of the Ethereum technology stack.
5) Technical Differences Between J.P. Morgan’s Private Ledger and Citi’s Global Settlement Expansion
Even though both systems share an EVM foundation, J.P. Morgan and Citi’s on‑chain strategies differ completely in purpose, scope, and operational design. J.P. Morgan uses Onyx, JPM Coin, and Liink to build a closed private ledger that processes payments inside the institution and among selected participants.
J.P. Morgan’s model handles payment automation, liquidity management, and real‑time inter‑institution settlement within its own network, with J.P. Morgan directly controlling network governance. As Quorum has been re‑architected on Besu, EVM compatibility, bridges, and asset movement with public Ethereum are now possible—but this stack is not designed to carry the world’s cross‑border payment flows.
Citi’s Swift Digital Ledger model, on the other hand, keeps the SWIFT network that connects 11,000 financial institutions worldwide intact while extending only the payment and settlement layer onto blockchain. This is a global payment infrastructure that integrates cross‑border payment authorization, settlement, and messaging, covering a far broader scope of international payment flows than J.P. Morgan’s private ledger.
In short, while both systems are EVM‑based, J.P. Morgan is building an institution‑centric private execution and settlement layer, whereas Citi is extending a SWIFT‑based global settlement layer on‑chain. They use similar technology, but the scale and role of the financial infrastructure they target are fundamentally different.
Conclusion
Japan’s on‑chain financial transition has moved beyond experimentation into a full redesign of global settlement infrastructure. With Citi Bank deploying a Swift Digital Ledger–based cross‑border payment system, Japan has clearly chosen to extend SWIFT‑centric global payment architecture onto blockchain.
J.P. Morgan, through Onyx, JPM Coin, and Liink, has built an institution‑focused private‑ledger payment network with EVM‑based interoperability with public Ethereum. However, this stack is not designed to carry the world’s cross‑border payment infrastructure.
Citi’s model, by contrast, preserves the global payment and settlement layer operated by SWIFT and extends it onto blockchain. For Japan, this is the most stable way to implement integrated cross‑border payment, settlement, and messaging at national scale.
In summary, Japan’s on‑chain settlement project is converging not on a Besu‑based internal network, but on a SWIFT‑based global settlement layer (EVM‑powered). Japan is choosing a strategy that maintains compatibility with international financial infrastructure while using blockchain to achieve 24/7 real‑time settlement and risk minimization.
