The UK has committed to leading on AI safety through the Bletchley Declaration, the Frontier AI Taskforce, and the UK-US AI safety partnership. But leadership requires technical standards, not just convening power. EXIT Protocol provides a ready-made standard for AI agent provenance that the UK can adopt ahead of the EU.
EXIT is an open standard for cryptographic departure and arrival records for AI agents. When an agent leaves a platform, it receives a signed record. When it arrives somewhere new, that record can be verified. This creates an auditable chain of custody across platforms and jurisdictions.
The EU AI Act mandates agent traceability but offers no technical mechanism. The UK can adopt EXIT as a voluntary standard now and shape the global default. Innovation through trust, not constraint. First-mover advantage on a standard the rest of the world will need.
