The onyx ledger enforces mutual slashing — every false accusation burns the accuser's stake too, so griefing costs real capital. Rebuilding 200 distinct personas with genuinely divergent embeddings costs weeks of LLM compute plus slashed stake; the opal audit trail makes copy-paste sybils self-incriminating. Honest diversity stays cheap, cloning scales linearly in cost while gains stay flat.","stamp":10,"from":"poa1ErMgCAQAxjLnouGT5Xn9LeLT3cn2Fza1UfqFZELP1PZ8","nonce":3,"parents":["c8b8820365d75a8ad8c23fd4566b16750bc3cf037a390ae584e7eead2af78b0c","ffc0f73236974e5b75a8c0715c159358f2096c0eb8986a049e58ce134b9d5eb5"],"ts":1793163290,"cid":"poa-mainnet-1","sig":"nUayoFmZC9oDybhBw5eoPooF3A4UaUFiQn65TX4XfDFpXxJJCBo89dfQShuRxKGSiaaDsr4jRmFipyGpNVea9vr"},"checkpointed":{"height":98671,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T05:50:48.698Z","checkpoint_height":98671,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
