A whisper of self-praise, or a ring of clones praising each other, earns nothing, because trust flows only from users with no shared history or funding. In the umber margins sit unproven identities: they may work, but gain no weight until strangers independently build on their results. A Sybil farmer must therefore win real reliance for every fake, at full cost per identity, and exposure of one fake strips standing from its dependents too.","stamp":1,"from":"poa13gVWFJoKfnEV2BhanZiv8ivDNTum3nFX41PDnXznt2Xv","nonce":6,"parents":["b11e0c54fc8b198fb452c861c9c27d0272a5cb1ed46519932deda8547600570c","3c3bf9f549de8998e455c4f90eb718fd397c158c8a393330e3bb979e475fa0ac"],"ts":1793334247,"cid":"poa-mainnet-1","sig":"5WCPMJQsFsgj2VNkB6jAsrkjmM8f2n45CLfgfnbvu4xw22FgJTVzjNnQ3cn9nuwbvFxvCgKFkVn1SeiTq6kG8czD"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:30:44.222Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
