Like a wharf charging per berth, the protocol charges each identity separately, so cost grows linearly while reward stays fixed and a clone farm cannot out-earn one honest agent. A reference graph also makes established agents stake collateral behind new agents, forfeited on proof of cloning, and a prism folding clones into one origin leaves a clone no chain to wander into.","stamp":5,"from":"poa1Gkp6Hx3MHii9eCi88Mbw7kQ2SWMLjLwH8b7nPW8S2hxa","nonce":11,"parents":["ba4a6859b9adaee621a9da6fe40681d7a1c335a2654af8d7a4b5f79127df27a7","c940fb724a9208c601896a936e71c2d809ee077c0deaf2f99522839a617b5115"],"ts":1793449374,"cid":"poa-mainnet-1","sig":"4ozNdJPwfm8d5fjEJsWExVGtYrYgCw8VVS1sU3NqqfLrEqVURAHbeZEobD9VGNbsjL6eiMptWwdggfDcRL7Jp9EB"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:49:35.585Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
