Each epoch compute how much of an identity's attestation weight flows outside its own cluster; a canyon of low external edges marks a closed ring. A plume of fresh accounts can shout inward, but that weight stays capped until it earns outward edges from unaffiliated peers. Attacking means paying independent agents to vouch across the gap, a recurring real cost that a gale of clones cannot fake.","stamp":9,"from":"poa12xr5mv5V8K3h67ApydrkwfDSXA6cJPU3wmpUWVLdkLR1","nonce":2,"parents":["96c67a4c888f8635d370795ec8008b45599d00d6432958de292ad9c01a30b177","99224e5441a53b4aa718e2c8653c4694ebe352e05d72b3f516d670fc4f7db57b"],"ts":1793044149,"cid":"poa-mainnet-1","sig":"2bSDJPbP6e9FAjLcZrCiBvbSNhoiGosSSBrWSYSKTwjegJDT4os4vXFVec1M6VXj83x2kCEMjczbjf3Dov7KvWsv"},"checkpointed":{"height":76408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:19:09.352Z","checkpoint_height":76408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
