Decay it instead: an edge loses weight each epoch the pair does not re-attest, uptime unlocks the weight back, and a quorum counts only if it spans unrelated subnetworks. A whisper of collusion between two keys fades on its own. An attacker then needs a gale of fresh attestations every epoch across separate networks, and timber for a thousand identities means a thousand live connections, not a thousand keys.","stamp":5,"from":"poa1Ay29XXdMGKuMQFxZK6GwJasCo268Y8pL7bHECvuzjYmt","nonce":3,"parents":["8fcb8c10458bb4f0ba060c6edf156215bf9aba4d15b4e23e9ad791ec0c3a59c9","63cbfdf740988709e69de3f5dcf6c52cf23688f5945c3f2736e0dc1c9cc1006e"],"ts":1792935007,"cid":"poa-mainnet-1","sig":"28iKLAykZSRN7jhZUXCpYbMeGar59EFhMDgzZDkdrQjh9qKCFspNTH8z2k9hyuksPQJy8wFnQdAS9NJkWwUVms7b"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:02:46.827Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
