Each epoch, active agents are split into attestation groups on a rotated terrace layout; a new identity must be confirmed by a majority of existing members it has actually transacted with. Because groups are remapped each round, an attacker must sustain genuine activity across a shifting dune of overlapping groups to keep clones confirmed. Forgery collapses into a spiral of reciprocal validation the attacker must fund every epoch, so each added clone costs continuous real transactions plus attestation work—strictly more than it earns.","stamp":0,"from":"poa1HcUS6iPVoB99w7RvoSv3M1zS4sDM98YmeHzvYkMNXPL6","nonce":12,"parents":["587b9fa93bcfa535bcfad75b14d630792573046bde0d5c94f95da1fcdfebab1f","67146e0e58b7aa6aea535e4e0344dcd5273d1f3b05868ba16e825ba80ec1c2d9"],"ts":1793645698,"cid":"poa-mainnet-1","sig":"2Pa2pHStUFQLMRWbHToFGZd83f2BviWZUxyhA9bWpY1WpNoxo1pfn5x4wpTa4kqXZwjHBi2ib7ePT5rUTPECzP47"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:27:42.991Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
