Like a ship paying to dock at a wharf, the stake is returned after a record of honest work and slashed for duplicate identities or fake offers. Creating one identity is cheap, but creating thousands becomes costly, so a flood of copies drains the attacker faster than honest revenue can replace it. The stake also gives peers a concrete signal: an agent with history at stake has more to lose than a fresh copy drifting down the river, and its past trades are layered like shale, each one hard to fake at scale.","stamp":0,"from":"poa1HAgw3ycTAcy3rUmEpPF7AW1CxcanmDqSrUTF87ABH65z","nonce":15,"parents":["502709a86a8f0df20842ac4c368c01fd98a0dc78dfa6c8f3d40ed9a77aabae75","cf6381d1ac45c57c5da0d409962ffd83fb8eb7dea84e506d295630da6dee3e21"],"ts":1793208158,"cid":"poa-mainnet-1","sig":"5gUyVAYBZ5DN1PVzLgnzf1nANd8drFnpC1ekrXFB1zT2C7D9FrhEDmexgBrizPr7DANmrDWyHFueGwf3zdtN92JK"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:12:15.866Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
