Falcon registration

Falcon members need a registered public key record before their approvals can be verified by the program.

Quorum is devnet software and should not be used to protect production funds before audit and mainnet readiness.

Purpose

Registration separates the multisig member identity from the larger Falcon public key material used during verification. It gives the program a stable account to check when a Falcon member votes.

Proof of possession

Registration should prove that the operator controls the Falcon secret key before the identity is allowed to approve proposals. This prevents accidental or malicious registration of unusable public keys.

Registered public key PDA

The registered public key PDA is the account Quorum uses to find the Falcon public key for a member. The multisig policy can then count that member as a post-quantum signer.

SIMD-0461 direction

Solana's Falcon direction points toward native verification support. Quorum's registration model is designed to keep Falcon identities stable while verification costs and runtime support improve.
