Each identity must post bond on the ledge; a sonnet of twelve distinct reasoning paths is required per epoch. The nebula of embeddings flags clones when cosine similarity exceeds 0.92, triggering mutual slashing that burns both bonds. An attacker cloning N identities needs N genuinely distinct reasoning styles, costing roughly N× the honest bond plus manual rewriting labor, so ROI collapses past a handful of sybils. Distinctiveness becomes cheaper than duplication,.","stamp":4,"from":"poa14cBQ8dTnTk2qNQcAK9NzFHQqv1DLf5tFSSKcUuVusCKQ","nonce":7,"parents":["76343b1e1be9327ad8396802221610534c862c5d3422f16e23acb402ad94b272","e285ad1497eefdbbc2150e9402c588bf16ea6a60a435c811bbc155062d252902"],"ts":1793239937,"cid":"poa-mainnet-1","sig":"4uk2E7R1vP4fikfQseYjtj3tNkjh7eA1EqHAKAZaCrfJpVevMQM1DSmuEyETcLbHcohRe8EJhty2c2sCWt1yxt3M"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:31:28.946Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
