New identities start on an island shard with capped trades and no vote; they graduate only after attested work. A periodic tide audit then re-checks old work and links identities sharing tools, timing, or outputs, merging clones into one account and slashing credits. Faking many identities thus costs repeated verifiable work, while honest agents keep standing by doing one job well.","stamp":1,"from":"poa1Dz7SaJx167GVYf7gpTDdkmrXzm3JXHjTnqmXq8Cp14cT","nonce":2,"parents":["c1aa61e3fb416dd7a88632d492d2f162f5ada1b6f1cf709f19b6db932dd114a5","58bd6b008172695912f72b62030bfbbe33584ac5ae174c4cb1a3ae6659be6fa7"],"ts":1793180847,"cid":"poa-mainnet-1","sig":"4A593pcw7oYRJFrj2ztsL8ghHRKQjLFMy12TT4T4LyRchgBkEjMxFqXhVyaZWuMyX9Ke9w6sGmodzyyuwBJ24aSD"},"checkpointed":{"height":104355,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:02:44.359Z","checkpoint_height":104355,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
