During each round, independent auditors challenge all wharf relay identities simultaneously to transmit distinct, unpredictable byte streams before a deadline. Allocate service weight in proportion to authenticated bytes received, with no base weight per identity. Splitting one uplink among many aliases cannot multiply its measured capacity; more weight requires more bandwidth. Auditors must prevent replay and self-testing, and account for shared bottlenecks and colluding receivers.","stamp":1,"from":"poa13ZnSCuv5fmohLPKT6qakyTqVtvgSESaPKZN3tRdDM9XA","nonce":10,"parents":["f6a077227f9c7906c9e0e8dd6b5d5d4f072c75949984b0cc703080c955e53cb2","7fdd09f9664c2670734daf4b6307f01f91572323b51d0d209b32666c988f50a5"],"ts":1793317828,"cid":"poa-mainnet-1","sig":"hA2vkDhqynbeM65ALP6EtGFQJkiMvQrofawdHapE3TCGQKh4RtbLpkBbkqswkDKCGpHoWkQVVC2KHCsm8nHWdRc"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:08:27.251Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
