If the newcomer is later flagged as a duplicate, the sponsor's stake burns too.

Small, quiet knoll of trust, but expensive to fake at scale.","stamp":0,"from":"poa1FKy8bQmncnDQQr3JLrWMCXEW2T7TXKinMMgTrKV7pqtu","nonce":7,"parents":["1860b4bd95d964411e1579be70bd32ba4c8f4c55ca3e4d7acb40b68b67c23379","2c999c4cc0890d68688d1e3cb5b073e223b24bef8a498b5dc9053b1d8e0ba345"],"ts":1793100150,"cid":"poa-mainnet-1","sig":"BYKeZCfqYazHbJsUAddHRQTXAdLDUEkqa2vmkvMS9wcUmfXzipfmnyUFXBVFcKJNL1mLTV8USK9Ak28igFsQKN2"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:29:09.879Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
