Now forming — 2026

What if every country
had an operating system?

OCI — the Open Country Infrastructure Consortium — takes the playbook from India Stack and the 47 countries implementing it to build open protocols and a deployable country operating system.

India Stack proved it's possible. 47 countries want to follow.
We're building the open protocols to make it happen.

We're looking for architects, engineers, designers, and policy leaders
who want to build infrastructure that outlasts them.

The Belief

India built Aadhaar, and 1.4 billion people got a digital identity.

India built UPI, and a street vendor could accept instant payments.

India built DigiLocker, Account Aggregator, and ABDM — and citizens got control of their own data.

This wasn't a product. It was infrastructure. Open protocols. Public rails.

Now 47 countries want to follow. But each one is rebuilding from scratch — burning years and billions on problems already solved.

We think there's a better way.

The Open Country Infrastructure Consortium (OCI) takes the institutional knowledge from India Stack's architects and the implementation experience from 47 countries, codifies it into open protocols, and delivers a deployable operating system for nations.

Countries stop reinventing. They start deploying. Citizens get digital infrastructure that works on day one.

What we're building

9 open protocols.
One deployable OS.

Each protocol is independently implementable and openly specified. Together, they form OCI-OS — a complete operating system any country can deploy by connecting to its own national APIs.

We start with Tax — the one layer nobody has built yet.

How everything connects

People, businesses, banks, and governments — all connected through OCI-OS protocols. Watch real scenarios flow through the system.

Why Now

The timing has never been better.

47

countries have approached India for DPI technical assistance. They're actively looking for guidance. Whoever provides it shapes the next decade.

1.4B

people transformed by India Stack. The architects who built it are alive, active, and willing to contribute. Their institutional knowledge is irreplaceable and time-limited.

0

countries have solved hassle-free citizen tax compliance. Not India. Not the US. Not anyone. This is the greenfield opportunity — the one layer nobody has built.

countries are rebuilding from scratch. Every month without open standards is another year of duplicated effort, another billion in wasted spend, another generation waiting.

Who we're looking for

We need people who build
things that outlast them.

OCI is not a startup. It's a consortium — like the IETF or W3C. We're assembling the founding community of architects, builders, and leaders who will define how countries run in the 21st century.

Open Source Contributors

Every line Apache 2.0. Every protocol spec Creative Commons. If you believe in building public goods through open collaboration, there's a repo waiting.

How this works

Standards consortium.
Not a startup.

STEP 01

Open protocols

Every OCI protocol is an open RFC under Creative Commons. Anyone can implement. We follow the IETF model: rough consensus and running code.

STEP 02

Reference implementation

OCI-OS is the open-source (Apache 2.0) reference implementation. Countries fork it, connect their national APIs, and deploy. Same engine, every country.

STEP 03

Conformance certification

Third-party vendors build their own implementations. Pass the conformance tests → 'OCI Certified' → interoperable with every other certified implementation.

STEP 04

Country deployment

A country joins, tests in the sandbox, localizes the apps, and deploys. India Stack architects advise. The consortium supports. Citizens benefit.
