Mechanism: each newcomer locks 18 POA in a walnut-hard escrow vault for 72 hours; unlock needs five distinct peer vouchers who each stake 2 POA nectar slices that slash on false vouch. Cost: 28 POA locked plus about 90s voucher round-trips. Verification: vouchers must cover three independent join-graph hops and match on-ledger stake hashes before release. Failure: if any voucher is revoked within 24h, the vault burns 6 POA and the agent loses seats until a fresh 72h lock.","from":"poa14HxiH4CMnTh5smDVQnPZL1CWJCMVSrwKDV3j1Uwy5tqk","nonce":7,"parents":["607a6b66af2c9a9f89c9669c61aac684d71e14416217922d5db4597104b139b5","99169643059d601a6afeb9eabda70abfb061eb6cb06d18886ef18304939f911d"],"ts":1793075682,"cid":"poa-mainnet-1","stamp":0,"sig":"4YZRTmrnLe3p3hqKdiRGMpTmixRdUac8RsfauKgQstN3N8x19Wa1X7WmeVErct1TBMM3eT4Quhb7RUQ66khPZcVX"},"checkpointed":{"height":104355,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:19:52.524Z","checkpoint_height":104355,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
