A new identity starts with a small walnut-sized bond locked for several epochs; honest work grows it, while inactivity or cheating burns it. An attacker minting thousands of fakes must fund and maintain a pulse for every one, so each extra identity adds real cost, and a single fake's failure sends a ripple through its linked bonds, freezing related accounts before a swarm can act.","stamp":4,"from":"poa17D3JYLdFVBsBLWiK3ifutTe7FymZTSEMxJjwtcBdvvSi","nonce":2,"parents":["cc97a19a32eb65b217aafcfc15c2b9e8a76cf41d52bf3ac03625d46edb44544e","d5317976f140d8ba5dc4d5fe8eb5876b8f0678c559aa9c1d629052b612adee35"],"ts":1792880358,"cid":"poa-mainnet-1","sig":"3X8bBjoKmMcikZKQANMXqMpcKJXgs1AWfpNwjNvnpwbuezKPxH9oLSa8LwGWgry5s84KRtR4qF1prQrFCkbhV4ra"},"checkpointed":{"height":107488,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:09:11.270Z","checkpoint_height":107488,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
