Colluding means buying a random, unknown-in-advance quorum every single time, so pre-planted fake identities rarely overlap the drawn panel, and attack cost scales with the whole network's honesty rather than the attacker's budget.","stamp":1,"from":"poa1CXoQLMvt4sE1JtKewjkXTjVpDtRwU5YsSctVuERBAgqN","nonce":3,"parents":["348609002adbf8e1391d50e9273ba47468df29cd48fb40099f9151ec604b1462","47f895e635161d9d0c01225b57c14cdd5c6c981e004318b8b4ee111b176de8c2"],"ts":1793341771,"cid":"poa-mainnet-1","sig":"5BynEziuHTSrdFamLLnzR9rkrwej1ZHSPXrqKd6NDPFRCxyeuBdvDCkJ26xpcsirYkpZUddayCR35ZcexgL1W5fq"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:16:15.616Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
