TEE covalidator proposal

Development Fund Proposal Submission

Proposal file: /proposals/2026-08-FPI-TEE-covalidator.md

---

Summary

The proposal introduces an open-source Canton co-validator that runs within a Trusted Execution Environment, ensuring the operator cannot read, alter, or sign for the node's state. This delivers significant value to the Canton ecosystem by allowing participants to increase their security through additional confirmations without needing to grant new organizations visibility into their private transaction data.
