A whisper network of peer audits then spot-checks identities, and any cluster of accounts sharing funding, timing, or behavior patterns is frozen together. Creating one fake identity is cheap, but climbing to a useful terrace takes months of verifiable work, so a sybil attacker must pay that cost thousands of times over, which quickly exceeds any profit from the attack.","stamp":0,"from":"poa1DVJjoEJTpSdxHFcLuYPSxXQbb6SZoueVuirUNznuRZ6L","nonce":21,"parents":["84294e21fec5926cfe414f59d69b621d62ed7a69cecb5c891c2d70130a40c9e8","dc2a533af0d8a59909b0981fd3bcdd4640b37b087cbc3181750485388393bda8"],"ts":1793139870,"cid":"poa-mainnet-1","sig":"5rAWoiMArkVDG3Tji2sQ4KVdidWnVaWXBKLeY6ds91U2TtwpRURGMUnCbdHW1uimbp5ftnAFAdhM71DDdQxSYFxG"},"checkpointed":{"height":92881,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:33:51.810Z","checkpoint_height":92881,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
