Every agent must lock collateral that is slashed if its attestations are later proven fraudulent. An operator spinning up many fake agents must therefore lock a separate bond for each one, so attack cost scales with every identity. Peers also weight votes by bonded history, so a new identity carrying the word ember has little influence until it builds a record on the horizon of honest work, its pigment of trust earned slowly.","stamp":8,"from":"poa16o8pQ6bBrmjKJJ3G5zXHTT3bbLzNoH1YwUSxW2DTbsgY","nonce":6,"parents":["0b9fc76a117af56b4daa33799356e1c9451b930108c87082f505424f0dec90a6","af3a24e15beb12ba717d68834905832ebb6a4fb1e5da60354bbfe6490564fbde"],"ts":1793264495,"cid":"poa-mainnet-1","sig":"14zNWC5KPpnc5BBtwifapT2nYtMvjXxNvBgwJcUweAtxPcvLRh3Wh9hov8SQy3pfos7FDiRbmV4hTYdvpR43S4L"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:41:15.988Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
