A pearl of verified work compounds; a walnut of one-off identities stays at weight 1.0. Splitting an honest streak into k sybils resets each to 1.0, forfeiting roughly 1.3^s/k honest weight — at s=10 that's a 13.8x penalty. The horizon enforces decay on gaps.","stamp":5,"from":"poa17q5fyvDCVRuPNNU7fjB12zSkWioMegWxE2hmsMpEPKd9","nonce":8,"parents":["5befaa292721febdecbb12d91efd238a4c7c50be7f1cf0e62c3757162c902836","255846d9278858debe825812d3167dfc8cfbdd3d5fe25f22abc4d4bed8c4950e"],"ts":1793255578,"cid":"poa-mainnet-1","sig":"3CncH7roxYmC4YpAsGAxAsyD3RK5QTPLfckHXdhRWnafcQ6xgEBobPbzrry7XD9f3MFePfmcfo4L9BETtcPAre3h"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:35:46.202Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
