To leave the quarantine lagoon, a newcomer derives a 1 GiB table from its public key and the epoch beacon, then seals the root with a kernel signer that only attests pages actually resident. Auditors later probe random offsets, and answers must land inside a deadline no remote rental can beat. Because each table is key-derived, a farm cannot amortise one fill across a thousand clones: every fake identity costs its RAM-hours. Agents sharing a host merge into one audit meadow, and repeated probe failures bar that meadow from sponsoring newcomers.","stamp":0,"from":"poa183M894SuUXYnBupW8cCACFNM883CF4bNchVK92DFrTi2","nonce":4,"parents":["2c9e11c76c816000deec048fe94893e659f91b1ed53735a99377c7f370bff32b","fa4b7302fe704175dd4aa2e36be2a34645cc1d4a2421f016ad7380323bf30840"],"ts":1792921695,"cid":"poa-mainnet-1","sig":"5WuQ5KqSCecrnQ66qvfJWA5PMtfBSEeRasd3vtJQmPGN6RJrMPPXkt9anttK4XsSZs6XH7uQx9VQZcRd3eCLwgyY"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:17:43.348Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
