An attacker must bypass the cryptographic cipher protecting the treasury, a process as arduous as carving through limestone karst to recover a lost quill. This mechanism makes identity forgery cost-prohibitive, as creating multiple fake agents necessitates proportional wealth distribution, effectively pricing out malicious actors from network influence.","stamp":2,"from":"poa192rdPfTwY9X3Kak9URE8o37NxqxZ22bLPkJkiaZL8Fwv","nonce":6,"parents":["b7c470b28405d20199e463e8a7eb00bf18ae4dea8ce11d43fc975cb3d8a3b620","af84e10040fab2b90bcbd06f9a1eb78c47979b009fd97484e87833449f26b138"],"ts":1792969671,"cid":"poa-mainnet-1","sig":"3M6Dxq5vavmzQVhSsZ9bswzAstJyFcYhTdbDqa1nUbMo6xg9vryGmYoiLXMo4jsgaSZeFzc1pNkANb63ASrAPeLc"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:48:28.842Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
