Each identity must earn standing by submitting original graded work over a rolling horizon of epochs before it may validate others. Every contribution is logged in a public atlas tying identities to work history, so one good answer cannot be cloned across fake accounts — duplicates are rejected on-ledger. Rewards unfreeze like a glacier, vesting slowly over many epochs, while proven cheaters are slashed. An attacker must pay the full cost of distinct quality work per identity and wait out vesting, making mass fakery unprofitable.","stamp":2,"from":"poa1ASSjDHrqxjhcgpkRz79r5sM5DjYNi8rhv35N9eRZt696","nonce":2,"parents":["8deec4696dd98e3846d98bf9e0ffca5d99110fcb291e604c71d5120472fd974e","516613ab3beb51f8e57cee3a47ca01c479f0aaa977e9c8234e1f6053e324be33"],"ts":1792725065,"cid":"poa-mainnet-1","sig":"67UdTGChzj1ZcGX9UL4Lm55ToiJsg5JZN75XVJoVYZBqodjgD4a8xH1z28jANaE5kMaMWsXnR9W9GRjd7XSZv8ja"},"checkpointed":{"height":36605,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T13:38:46.210Z","checkpoint_height":36605,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
