How BRICS Pay works — the four pillars

Every big payment system rests on a few pillars. SWIFT had “a single message standard + a network of correspondent banks”. Visa and Mastercard have “a global card network + an association of issuing banks”. BRICS Pay’s pillars are different — modern, technology-driven and resilient to political pressure. There are four, and they shape the entire design of the system.

Four foundational principles

What “decentralisation” means in practice

The word “decentralisation” gets thrown around so often it almost loses meaning. In BRICS Pay’s case it has a very concrete technical meaning.

Picture this: SWIFT is a giant switchboard in Belgium through which every international banking message in the world flows. Switch that off tomorrow (technical or political) — half of world trade stops. SWIFT is therefore a centralised system with a single point of failure.

BRICS Pay is built differently. Each member country runs its own server (or several) that talks to peers in other countries directly over a secure protocol. This is a P2P network (peer-to-peer — the same architecture as torrents). If servers in one country are switched off tomorrow, the rest keep working. If two countries have a falling-out, third parties can keep transacting independently.

That gives resilience: you can’t turn the system off with one political decision. And it gives equality: no country has privileged access or the right to block others.

What blockchain is — in plain English

“Blockchain” is probably the trendiest and most opaque word in fintech. At heart it is a secure database that you can only append to, not edit retroactively.

An analogy: imagine a ledger where every entry is sealed to the previous one with a mathematical “fingerprint”. If anyone tries to change an old entry, all subsequent fingerprints become wrong and the forgery is immediately obvious. Plus the ledger lives in millions of copies around the world: forging one record means changing all copies at once — practically impossible.

In BRICS Pay blockchain isn’t used to store money (the way bitcoin does), but to keep the transaction journal. Every operation is written into an immutable log seen by all node participants. That gives transparency (anyone can verify any operation) and fraud resistance (you can’t alter an amount or a recipient after the fact).

How integration with national systems works

Every BRICS country has built its own fintech infrastructure over the decades. In the 2010s countries put huge investment into national payment systems — SBP in Russia (since 2019), UPI in India (since 2016), Pix in Brazil (since 2020), PayShap in South Africa (since 2023). They are successful and loved.

BRICS Pay does not try to replace them — that would be expensive and politically impossible. Instead BRICS Pay plugs in “on top” via a standardised protocol. Technically:

1. A tourist in Brazil opens BRICS Pay and scans a QR in a cafe.
2. BRICS Pay recognises this as a Brazilian Pix-format QR.
3. The app converts the request into Pix format and sends it into the national Pix network.
4. Pix processes the payment in reais inside Brazil.
5. In parallel, the tourist’s linked BRICS Pay card is debited in their currency.
6. Between card and Pix sits a “bridge” — market-rate conversion through DCMS.

To the user it all happens in seconds and looks like one tap. But under the hood four systems cooperate via a single protocol.

Simplicity is the main product principle

In UX, anything more complex than “tap one button” is too complex. So BRICS Pay follows the principle “if it can be automated, it must be automated.”

• Sign-up — 2–3 minutes by phone or email.
• KYC — passport + selfie, in-app, no office visit.
• Linking a card — like in any banking app.
• Payment — “scan QR → confirm → done.” No currency choice, no manual conversion, no recipient account number to type.
• Protection — biometrics and a passcode, nothing harder.

Complexity is hidden inside: blockchain, DCMS, multilateral netting, CBDC bridges — all run on the backend, the user only sees the result. That is the right product approach: technology shouldn’t burden the user.

Transparency as protection

Transparency is a political word, but in finance it means something very concrete: every transaction leaves an immutable trail in the system. It cuts both ways.

For users it means you can always check the status of a payment in your app history. Not “the money went somewhere and got stuck” — but a concrete path: debited from card, processed in DCMS, credited to recipient, transaction ID, timestamp. You can cite that record in a dispute.

For regulators and society it means suspicious transactions are easier to find. AML systems automatically track anomalies: sudden large transfers, chains that look like “laundering”, transactions with addresses on sanctions lists. All of that is blocked before money moves.

Key benefits — what it means for users

• Lower costs: potential reduction of cross-border transfer costs of up to USD 15 bn annually across BRICS+ trade.
• National-currency settlement: support for member states’ local currencies without forced USD conversion.
• Economic growth: new opportunities for trade and cooperation across BRICS+.
• Financial inclusion: access to international settlement for SMEs and individuals previously priced out of cross-border work.
• Financial sovereignty: reduced dependence on Western financial infrastructure — without isolation from the global economy.
• Tech innovation: spreading modern fintech solutions across emerging markets.
