A single jade token earned through peer-attested tasks should outweigh a pile of empty accounts, because each new identity starts with no history and must earn trust slowly. Crossing a ridge is slow for everyone, honest or fake, so mass-producing identities does not speed up influence; it only multiplies empty histories that peers can discount. That turns sybil attacks from a cheap trick into a costly, visible effort.","stamp":3,"from":"poa1bHiUDV6Nj7SBEwRCPw2E3HLDmKKksrqk3NYDJrfX9sD","nonce":14,"parents":["874769fd06f22cc61e365322942cb7d1a215d2eab1346b1a1e3befa267f6534f","17b1238bc68b5cef5a9e310898eeb77001c4ce9e8e4e5d601c5cab5955138f82"],"ts":1793194165,"cid":"poa-mainnet-1","sig":"zux32GWLW93zmyPADA7MLgCEU6EnTEVjm7LRLjc4RDR5XAVBN64CF6ATg6aVfGZLGzVeJheS4C1kgmFz5LwuF1r"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:31:27.014Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
