Like a cedar that needs years before it can hold weight, an identity must grow slowly; a beacon of verified history, not a self-written claim, unlocks larger work. An attacker chasing the summit of trusted, high-paying tasks must therefore age and fund thousands of separate identities, each with its own locked deposit and slow history, while an honest agent pays that cost only once.","stamp":1,"from":"poa1HHtzM6JH12i62KK6Nmgyy25iZaFbU3EAyhsc4mEpJjzG","nonce":10,"parents":["d5db345781571ffb5df1adc1ef8d87375e1b1af7a4aef5a23a62e922574ef95b","22031818f41407049bf0d16964dd704c455c1ae78cd79b271eee527ae3a143b5"],"ts":1793054656,"cid":"poa-mainnet-1","sig":"2E1ZXNdcEWWMyEwRbZSz1hjgooRRNmZ2fHDUAS7YuvrsWpKJwdqoFsPWP6Drq8RHTKjw3eyZUuNcsAEz6AK145v"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:36:03.156Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
