Empowering Innovation Through Open-Source Excellence
National Node Net is an open-source platform that enables organisations to build trusted, federated digital ecosystems. It provides the core capabilities needed to connect organisations securely, establish trust between participants and support interoperability across organisational boundaries.
Originally developed through the UK's National Digital Twin Programme, National Node Net has grown into an independent open-source platform. Giving it its own identity recognises that it is no longer simply a programme deliverable, but a shared platform that organisations can adopt, extend and contribute to.
Today, National Node Net is developed in the open, with a growing community of contributors working together to build trusted digital infrastructure that can be used across sectors and domains.
Why National Node Net?
Organisations increasingly need to collaborate across complex networks of partners, suppliers and public bodies. Whether sharing operational information, supporting digital twins or enabling cross-sector services, secure interoperability has become a fundamental requirement.
Building these capabilities independently often results in fragmented architectures, duplicated effort and tightly coupled integrations that are difficult to evolve.
National Node Net provides a common foundation for trusted digital collaboration. Rather than creating bespoke integrations between organisations, it offers shared capabilities for identity, trust, federation and discovery that allow participants to connect while retaining control of their own systems and data.
This enables organisations to focus on delivering value through their applications and services, rather than repeatedly solving the same infrastructure challenges.
Open by design
National Node Net is developed as an open-source platform because openness supports long-term interoperability, transparency and collaboration.
Its source code, documentation and technical decisions are developed in the open, enabling organisations to understand how the platform works, contribute improvements and build on a common foundation. This approach encourages interoperability across implementations, reduces barriers to adoption and supports the long-term sustainability of the platform.
Whether deploying National Node Net within your own organisation or contributing new capabilities to the platform, everyone works from the same open foundation.
Built through collaboration
National Node Net has been shaped through collaboration between government, industry and academia, bringing together expertise in digital infrastructure, interoperability and distributed systems.
As an open-source platform, its continued development depends on a broad community of organisations and individuals. Contributions are welcomed across software development, architecture, documentation, testing and real-world implementation.
By developing the platform in the open, National Node Net can evolve in response to practical experience while remaining focused on interoperability, security and trust.
From programme to platform
National Node Net began as part of the National Digital Twin Programme (developed under as the “Integration Architecture”), where it was created to address the challenge of trusted information sharing across complex systems.
Establishing National Node Net as an independent project reflects its role and importance beyond digital twin applications and creates a clear home for its technology, community and future development.
Its foundations remain rooted in the principles established through the National Digital Twin Programme, while its future is driven by an open community committed to building trusted digital infrastructure for everyone.
Get involved
National Node Net is designed to be adopted, extended and improved by its community.
Whether you're exploring the platform, deploying your first node, integrating existing systems or contributing code, documentation or ideas, there are many ways to participate.
