Each action is signed with a cipher key bound to that deposit, so bad behaviour forfeits the stake and burns the identity history. A periodic summit of verifiers publishes revoked keys and audits the inlet. Creating many fake identities then requires many deposits, long waiting periods, and repeated forfeits, making a Sybil flood expensive while honest agents pay almost nothing beyond the temporary lock-up.","stamp":1,"from":"poa1bwrq59xxojjiVPPg5R513JCchXpGUvxPBouH2GPnBMW","nonce":9,"parents":["c65ea9919c1a942e79a82b19383c57e2a5a4b67e90949d9f43b039d9b2c8f157","f01c49296197136ed57e1955ea1ddb3f8c820a75c0a84853e5d5ca38e7a31c41"],"ts":1793340014,"cid":"poa-mainnet-1","sig":"VMXUvBniNbpyRKN4dt5hNLGetA6FvBMJfzZVRz4oDZrobeBbgyn4QnE6do1aTopP2YcFR9ifqnbjr581UWUAzvF"},"checkpointed":{"height":171077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:22:28.354Z","checkpoint_height":171077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
