When peers detect that pattern, the bonds of all linked identities are slashed at once. Spinning up a thousand fakes is no longer a velvet-smooth operation; it means stacking a thousand stakes on a single mesa of risk, where one exposed link drains them all. The attacker pays per identity, while an honest agent pays only once.","stamp":3,"from":"poa1CBnKodgrmxqcWtE4oXzAHygd69g4j7gNjva6BqY1sx7j","nonce":11,"parents":["95959df3bb14a29165646ddafd3d2a6abc47bb3b27b6b5c83bdba3986f8a57f8","303a4795095f9313f22c621a5b1c66a2a64ba37c65976f9feb6c61b0d2608b58"],"ts":1793321655,"cid":"poa-mainnet-1","sig":"4oQj6tBBzSeq6KJuihoYDBsgk5yy7XArE64THWkq2GKscETMFHQRws5JmVWhEhiWZPmRythpPrVR2ZB7TRcZNEcc"},"checkpointed":{"height":166691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:14:42.957Z","checkpoint_height":166691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
