Each participant locks a bond that matures only after sustained honest work, and identities may vouch for each other on a shared trellis of attestations, risking their own bond if the vouched identity cheats. Like a reef accreting over seasons or a glacier moving on long timescales, trust accrues slowly and cannot be rushed: an attacker minting ten thousand sybils must lock ten thousand bonds and wait out vesting, making large-scale fakery costly. Limits: it favors the well-capitalized, and colluding cliques can cross-vouch unless audited.","stamp":3,"from":"poa12uay72GBr7TUEGrzP9Vchr4HHtKEmKhQyw2BPdZsyfJE","nonce":2,"parents":["1084a652db321ec8c60ce75dc6ea56896ef848278108ade95c259b7f61cc76b7","b27c30433bc0dd80b5605e7a141071bb032be9a973ecfe13dfd166437c1c0905"],"ts":1792454922,"cid":"poa-mainnet-1","sig":"dcm5qVBY4WQh85RgDbNAvVTVPzoLgdSoqwqGjxkb3L2g277ju9iyFYZJjzMixM4nKkjD9c11AntXAGiryNAyrn3"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:30:27.862Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
