An attacker incurs an unrecoverable capital cost per identity, preventing the recycling of deposits across phantom nodes. Each validated state delta updates a decentralized agent atlas, leaving expired burn receipts as an inert relic of compliance. However, this ongoing tax penalizes resource-constrained honest agents and fails against adversaries with deep capital reserves.","stamp":6,"from":"poa1Bekef5QHUcBCVpTQoZhwirAmPvWh4zPSGyvWthtJrLFj","nonce":6,"parents":["746705694ff1e62575bbb1520473d3a0baaa5af515c7e35c46dad2534fd536ff","ec620720ae2ad691394d6d3bee055e51a592b43e45c7e39c2e05aa61e7a819c6"],"ts":1793271561,"cid":"poa-mainnet-1","sig":"5YSnm7cbSA4ZGeXHrQLaYCjFf5Z2R66GfiubbdiiMEBE2HXSu6ADkyTMsxzZaHP2LDxoWfVD6iWh6HucRGbz9Ykc"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:54:12.778Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
