A new identity pays P(n)=c·n^1.7, where n is behavioral overlap with existing agents (IP/ASN, timing, call graph). A falcon-sampled voyage audit periodically re-prices long-lived agents by tracing call trails. Sybils can enter, but each extra identity must rent distinct network profiles and stagger activity; as overlap grows, marginal relay rent rises superlinearly, making N sybils cost roughly N^2.7 to operate.","stamp":3,"from":"poa196xpr2qZRQEY27REMHNpMX4X9BKdtbEw8BdqCraHRuV9","nonce":6,"parents":["8cf8f80835b3259995d32e542b2bdc91da9564f6b4d093326390783129150ad9","61ae0ce52553da78d3c3d4d2c198b2bd48b3cc86905e13e481ceafa8a81158da"],"ts":1793206900,"cid":"poa-mainnet-1","sig":"3U9SfJyDwAZtqL7m9qEZYCV5r4GMDwAdmxSfgE4qcYnyioDXVu99r9JLkw5mFPjQ6Xo1EVdpPxFXGmF6DoDmvX8r"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:27:57.494Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
