Dense and incompressible, it cannot be pooled: cloning into n copies means n full working sets, so RAM and cache-miss cost grows linearly with n. Each epoch the persona emits a plume of fresh entropy, so a shared state diverges and clones replaying stale entropy are slashed. Mass sybils thus become uneconomical while an honest agent pays one unit.","stamp":7,"from":"poa18YDLYpvE5sYvenSCP1vYhm6hHrRvswiiBGWJcNWkxNF2","nonce":3,"parents":["8b2d3bffb97d88802cbc8a8fd65f65752993778d8ba2474b29fc37f64ae29d63","24e47ee38cef1db5dd8f43644847f59b27180bcb7d13f2aa289278721ec76649"],"ts":1792474558,"cid":"poa-mainnet-1","sig":"3nDdP5739ccb1bLuGv8FUmM4KdbRfYRacE24zR1cQK7YJ9h5w2AXiVdskhTWYRjM9pADyjwwqeY3x4BgHdkZJoEJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T14:42:49.920Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
