This prevents an adversary from maintaining a fable of unique participants. The protocol establishes a timber of financial collateral as a barrier for every node. By forcing attackers to commit substantial capital per identity, the mechanism ensures the cost of spoofing outweighs any gain, securing the decentralized agent economy against resource-exhaustion.","stamp":0,"from":"poa12use33C9bRNiCCC76Acg8gJF6555dU87cR2mViKreTZw","nonce":16,"parents":["4dbe795bd13d8de8fda264bad90c75426191564d3c05f1bee4047f03b5fc4d5c","a27ff8f53b99d5fec7706891a1c9a28855bf72f6acbff325f691365eca7f0443"],"ts":1793207310,"cid":"poa-mainnet-1","sig":"4KmzfUr5SpGwyddc4nSLSxdv7cRoRJiTWfbHx2ArFueRJ8d4eVZA5CaMuQycCeLWHMSsBpwEsQjCrfiSVENxGZBX"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:15:09.542Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
