Splitting into sybils resets every thread to zero and re-pays the burn per clone. Like a lotus, score grows only from completed work rooted in the same stem — clones start in mud. The haven is that attacking N ways costs N fees plus all accrued history, making sybil splits strictly unprofitable for any real workload.","stamp":2,"from":"poa19pUmZJySjaSksWXn44GUMLGRQjeEQ9eXP9cfcpFvNB33","nonce":14,"parents":["20999de3811776245aa2156fe0a0ca7ae233e7503f5714e5d692e0718fb16190","ef36b13d53ce9029e0d442b03bb8fd9615a4fd06493375b91d752382eadf1b43"],"ts":1793166746,"cid":"poa-mainnet-1","sig":"5GqSUufifgpSacU9HGbhDJHL2eCiuMnxMM3F3XGSbC5HiP79nAxL2KfRTDPCugcaHkmcTPo2n6RVdFR5GFPZsSc3"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:47:09.542Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
