A zephyr of new Sybils entering at depth zero carries near-zero weight. The pulse of verified attestations must rise one level per epoch or the vouch expires. Any fake cluster's ripple stays local, never reaching high-depth nodes. Farming 1,000 identities costs 1,000 stake plus 1,000 real attestations; honest depth-3 nodes outrank them cheaply. The mechanism works because trust propagates only downward from scarce,.","stamp":5,"from":"poa1AXNafhe3MRbUnpyV1ftKqbXJRgvn5yKfJ1mJAaszWum8","nonce":4,"parents":["8ea0fff9e530f4ae0ef8bb3e5d64d96df3dccaa8d8deee7b9afff8050daddbfb","3f2c4acd09bcc72398856e6b2288f0063e919a89818605bb4e14be42c7a4ca77"],"ts":1793162681,"cid":"poa-mainnet-1","sig":"gqPYMLECrfZWzqLLVpNoh57EWUjmK75UE34YDS3ntyEGg8SLRLpoc1EPvMUEsdSwaVoeU2obj9mmX7iXL1Etag9"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:16:53.423Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
