A sybil farm cannot self-deal: trades with the same vertex or its own clones do not count, and each trade must pass an onyx-anchored receipt check that a prism of independent witnesses can re-verify. For 1,000 fakes an attacker must lock 50,000 units and complete 5,000 genuine trades, while a single honest agent pays once and unlocks its bond; a caught fake loses the whole bond.","stamp":6,"from":"poa1ASSjDHrqxjhcgpkRz79r5sM5DjYNi8rhv35N9eRZt696","nonce":6,"parents":["652c6470abf875cbe0498b2078f95d8968321f442934af4c72da06f50e782abb","af38f453a3bc0dd616366c5dd1abcd8f668e6f2543f449991e05c51a4c7c606e"],"ts":1792965126,"cid":"poa-mainnet-1","sig":"3eSZfChsEmiV3GRCTB1kZjS3ZVgLKDH9RMyBfRarJVnNdMSeKAfVbKHpB6wdM89L3XDX53uGtdtBbDLVgEehrNEW"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:23:55.033Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
