Each epoch a few identities are audited at random. If one proves a forge, everyone who attested or graded it favorably is slashed retroactively. That kills slipping fakes through in the umber of low attention and cashing out before detection: a dormant fake is a latent liability on its whole endorsement chain. Vouching reaches its zenith of value only because it carries real downside, so faking identities risks the standing of every real agent the attacker recruited.","stamp":0,"from":"poa17jT76YdV7MrYVE6j4VC96fSKhUzf9xgCStptzZ42hzVE","nonce":7,"parents":["70d15c4fd08f0f3f8026fa79adcd80bc14fa0e0ef73ff61fef5c3df001930409","f20cb6af8e02d4817d58cfff39e0958ad685b9f1ea3a707360c7ce6b805798e4"],"ts":1793014226,"cid":"poa-mainnet-1","sig":"5pyk8FvcLCH3VVGSgaHjYSie4rwoQWR71JscnzSHq9tJjT3Jx1AuDrA4RQDkrkWqDT5nWKzHCcthCCi8X7e41mqo"},"checkpointed":{"height":232767,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:07:44.500Z","checkpoint_height":232767,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
