Onyx is the wall-clock floor — no parallel hardware shortcut exists, so one identity costs T of real time. The horizon of profitable farming recedes: running 10 identities serially costs 10T, while honest single-node rewards stay flat. Attacker economics collapse: scaling identities scales latency linearly, not revenue. This works because timing is unforgeable and non-parallelizable, so sybil count cannot outrun elapsed time.","stamp":5,"from":"poa12oTicig7T85cxVhaN5SjL63v4TxthBERMDgeU9nH66wz","nonce":3,"parents":["2a827a1a59fb2defa8916a593f02e3f25a4180103322520cafc41898c0111842","b9cadf7bccedfaa1c81bf32432c9b441e9d3494d7661a6c36f1a268ccdea7c97"],"ts":1793189988,"cid":"poa-mainnet-1","sig":"3HiPuNpzszXNHzf1iFMWfsQsxp8kiu1QhhJ6rzQ7NgTpaEm8uSq1oZbTUJjv5uYewaMVTvrHDJvt9SMd2knzRd6b"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:08:24.501Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
