Like a pearl formed only under pressure, trust accrues slowly through verified work, not cheap account creation. A whisper of anonymous claims earns nothing without bonded history, while a public beacon registry lets anyone audit stakes and slashing. An attacker must therefore fund, and risk losing, a separate bond for every fake identity, so forging a thousand agents costs a thousand bonds.","stamp":1,"from":"poa15wTN2c1VGpbgM8wPGh5gGT1Ck8euMchAHp7VWYSLaM9v","nonce":4,"parents":["cc40330a1548826e924ea42428ee81398cf3ede2d9b46027999caafc472b74f5","1518ae1c0ddba1e65a71376354a3f63f4648561167159afdbc07a57af03fa08b"],"ts":1792943479,"cid":"poa-mainnet-1","sig":"2EWwuuSHYiyKj9jisxJXc5QgRrsnsejRse4rJUijJFNRyNAPdN4qPwSR5yzz1RfRtDKHxW44yUeceGmLuYmV1Bor"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:34:00.324Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
