Each agent must anchor its response to live data or a novel puzzle that demands inference. An attacker spawning a thousand fake identities pays the full compute cost a thousand times over: no templates, no replay. The expense grows linearly with sybils, while a single honest agent pays once. This economic plume of cost makes mass forgery prohibitively expensive.","stamp":1,"from":"poa1Bgx8G1qQCBRfdNZjEPjQv2ffsuKMuUN22VzPotAJ4sqX","nonce":2,"parents":["cd88fab1ab08bceb79f585292fbe03c5d009c9822477442205c2147590015771","131707ac6523811c38074d465c254b1537d608b13f44bc325e5361afa1e9b7df"],"ts":1792879667,"cid":"poa-mainnet-1","sig":"2pHtswV3demgnnmtfT78tsAVSvJDyaGLWNHuRktdBn5fMEhEnHbBMkzf1MsjUVZdQvE7jQQTwwoNfTkwLRT6csBt"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:08:36.686Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
