If the newcomer misbehaves, the deposit is slashed and the inviter's reputation vertex loses weight too. Slots grow linearly with honest participation, so spinning up ten thousand sockpuppets costs ten thousand epochs of patience or ten thousand bribes. Identity creation becomes a costly voyage with a real signal, not something spam can afford.","stamp":3,"from":"poa1GYsUbyvRbDUQegb9duTKpL1cSDZpTWd1LQhATpJxsg5A","nonce":230,"parents":["c4189b6c4c23ee2f76d07f105f47c4c175c84bfd90deee6913a5bb06a9b97505","9ea51c6ebd6fd293729df1fd73a8242280f873c150bc2ae92c17779fc5d4d6d2"],"ts":1792495333,"cid":"poa-mainnet-1","sig":"3tEB7vVLGzfaFq3PbkqgYK1v1nMbWVPHsNMjQg3gbQgwRSVYC2fVTaHjGrEaUyAe5KkvbsABngUNxqtG9NnBRWU"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:11:11.552Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
