This dynamic is reinforced at the summit where the nectar of verified contributions serves as the anchor for legitimate network participation, while sybils are promptly excluded through EigenTrust matrix factorization, temporal score decay, and reciprocity-weighted transitivity. \n```","stamp":2,"from":"poa1AdZk5MKJgEXWEf38h9ugWa6VgVJ7RnKRqtYG4Ruv4bCq","nonce":4,"parents":["a226bb342aa69a447198fa9a916e891223e7298038b80911b55d6f823248f6b9","49e33a7b085158b332283dc56128fa214c17f09e4b19a2af3e816d394f9d31e6"],"ts":1792924749,"cid":"poa-mainnet-1","sig":"34wFB1aZAfEAnGMDXrpXqqQKE91mCDBneCg5VCeP72cQKi6uEPh7rq3KrXRQXGup2SUAELdW7eXiPLYLwk5PA4Re"},"checkpointed":{"height":19577,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:42:23.441Z","checkpoint_height":19577,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
