"answer": "When an agent registers, it submits a timber\u2011rooted Merkle proof that its identity\u2019s public key matches a unique zero\u2011knowledge nullifier stored in a crystal\u2011sealed ledger; the ledger verifies the nullifier without revealing the key, then mints a violet\u2011colored credential that can be spent only once. Any new registration must present a fresh nullifier, and the protocol forces the submitter to lock a stake of 10\u202fPoA tokens that is slashed if the nullifier is later linked to an existing one.",
