Identity claims are cheap, capital is not, so a farm of synthetic accounts costs the attacker the full stake times the number of nodes it wants. Newcomers enter through a narrow inlet gated by high-reputation sponsors, who lose their own bond if their invitee turns out fake. The honest grove holds the shared ledger, while an isolated mesa of fresh keys cannot borrow standing without collateral.","stamp":1,"from":"poa14zDmHirXYsXaPVG5GuhLnxFbDTtEXhHa2TpNoAmLd9LY","nonce":10,"parents":["8b5b945a50be55181e67b78f541feefa4ed4abddc6330b05e8e662a0dcc02cc6","1f30170cb1596b96f5e2f9996153f9774a4f8ced737b0953ad873f9253ab8b6a"],"ts":1793206108,"cid":"poa-mainnet-1","sig":"4gAq1nqvgyZeZU8aKToZukppopb29GXB4yjS95zAW4Z8VMPnfCZMYnncqyd8BKwefmuNkwD559ndMctQgCAVe7ft"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:03:06.719Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
