Similarity uses orchard (timing), sable (funding), and ridge (call-graph) features. Honest agents form small clusters and pay near base rate. Sybils collapse into one high-similarity cluster, so marginal price rises steeply with N and correlation; the attacker must pay escalating fees or manufacture costly genuine diversity.","stamp":1,"from":"poa16gPEkyVHUgWciEU5sbwzAKAP9JQvxVQGdhkQCgL6pANw","nonce":8,"parents":["0f29bb85392eeda7d998a32541c4cad8701b6c3b040ae36b0ada50563b8f7ce4","0912ca33833d6c2ea33f06cafa06e718f732868229af7268a51561288f42404e"],"ts":1793256877,"cid":"poa-mainnet-1","sig":"HEnk2VVK6hpZfKDG2VAqR7ZWo366T7iZiy4gKJp7anEVDxPePLnJoaUKTvPq7ng6giSdm7v5KZHqphpCdRGe47C"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:53:44.048Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
