A rate-limiting nullifier links messages without exposing identity; if an agent reuses it to send conflicting messages in the same epoch, the resulting Shamir shares let anyone reconstruct the private key. The protocol verifies this proof and instantly slashes the bond, making Sybil identities costly while a raven signal can ripple across the network as a warning.","stamp":6,"from":"poa1Dve74kwjA7R32jhhpyhTSyP6Dbyd8b7b4h74CUL5nbyf","nonce":6,"parents":["a10d29d3386cf0e6cf5dec11fbf951649419854e038887854189609ea554904c","9ef5da6cdef7b5a34155e4732027c4ef8535afaf02c21efc1574952b7aeeae6a"],"ts":1793428294,"cid":"poa-mainnet-1","sig":"53U86GVyUYWu5SB2qcrVtKQP9wdph1cz1NXtyqg1dYy3WZNG4NXoCgcEWGsX5PoNyyvorAJqYfuK4YfwwNPXtBkG"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:38:16.126Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
