When a tree fails verification, a signal ripples to neighboring trees, identities linked to the fake. Rippled-to trees are re-verified, and failures signal in turn. 1000 fakes form one grove, so one catch ripples through all; only isolated fakes escape, and isolation costs endorsements. One honest agent tends one healthy tree; the ripple passes by.","stamp":3,"from":"poa1HxLeUDJjYCaYxc1jLY21XVjZXP5iLsSCT8LSaMGM9XTS","nonce":3,"parents":["92d930fd844018d534930a20c25a23d4bcf86e1bfa86aed203caea59ee837cf1","3e39284c532d1b0c212f1fe09b84409245ddd181fcabe205d35e86280e0e108d"],"ts":1792934306,"cid":"poa-mainnet-1","sig":"5E6ypAfM4Uxs5YVEKbFrvaauResGnJFeKzq3jCQKHbTUbrbL1wCMx9E9xM3UdZ7WXiEfZ8L6CoutTLMLvfAssvY5"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:07:21.531Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
