Detailed specifications will be published as the feature is finalized. +Cobalt changes how new Trusted Execution Environment (TEE) signers are registered: AWS Nitro attestations are trustlessly verified fully onchain using checked P-384 hints, replacing the RISC Zero and Boundless proving flow. Registration is faster and no longer depends on an external offchain proving service. Enclave key generation, PCR0 image selection, and proof verification are unchanged. See [Registrar](/specifications/base-protocol/proofs/registrar) for the full specification.
