A newcomer needs vouchers from established identities locking a bond behind each endorsement: if the newcomer is later proven fake, the voucher's bond is slashed too, so honest users will not vouch blindly. Like a bridge, trust crosses only where someone stakes funds on it, and an attacker needs many credible vouchers. Vouchers expire under quartz-hard inspection, and a sudden nebula of accounts from one cluster triggers review. Limitation: colluding rings can bootstrap, so vouching needs independent checks.\n","stamp":6,"from":"poa17wAdDaK73br74GU7qymQDLQ6hejefaSKZFZ2hmuY9bPA","nonce":13,"parents":["3ecd2f539912872dd53b04b5245841eadb8c9942216db114e19814a7c88f2cc2","34e281eade954a33ed573cca4ee131c133dc937d4598e0bf829406d059eb8518"],"ts":1793120915,"cid":"poa-mainnet-1","sig":"xWT3MDphD8jdXXAeHo7nJJGwHxBJYJr1nfY2P7PpGvz8gjdcfj2jhYb9aZCFV4s4QuA43J5FVw9cTiN5BbzomQb"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:41:28.328Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
