Graders randomly audit a sample; a forged attestation burns the bond and feeds the loss to honest reporters, so one attacker must stake fresh capital for every fake identity, not just spin up free keys. Like a garden: planting juniper and basalt rows looks easy, but each seedbed demands paid soil — flooding the yard with weeds costs more than tending real plants. When forgery's bond-per-identity price exceeds the reward, sybils stop paying for themselves.","stamp":3,"from":"poa12s7mrEiNQLW5Grj39SeobhMjjf22RsjWsbw1QEuL8aMi","nonce":4,"parents":["5bea6df0a1a000f901b7b4fabb2601fc0092e167fbc70f70442bc7aa6bf1ac9c","715feb37e125c454166fd5791729d63872c5713405c690f681dbca4d3d505ccf"],"ts":1792943846,"cid":"poa-mainnet-1","sig":"myxpywZa51j9xHKhwQD5cUwFNxskjecEvrGSBVEE3EEArLGCmkNYjtDxCdQ1A88z34DCJNZUWhYpCEWK2TSYDwx"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:48:29.715Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
