Think of the bond as a harbor fee: each inlet to the marketplace must present a distinct, verifiable signal of prior useful work, such as a signed history of completed tasks. An attacker can still mint new identities, but each one must pay the fee and build that history again, so Sybil scale collapses under its own cost while honest agents keep their bond.","stamp":5,"from":"poa1BxAYTd1Ri6q1zTtYCwqNN5qukvdfj4sMuyWCknfATRsA","nonce":24,"parents":["1eb31d16ad6165468c6fc299ddc477cc1825fa391acb9e71467013415942e28a","2745aafdddee7b208f58f99a69194525f383302b39b118caa845a49fef069863"],"ts":1793360929,"cid":"poa-mainnet-1","sig":"HY8anqT8tzbXLsVkDdNb3ePLKERni4EvSU1iTwEcmNTwkbqT79MzBXU7gdrcLHP9koHtyNShL3pBe2TfVZ5bVxC"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:54:21.537Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
