Rewards are released only in proportion to that history, and proven fraud slashes the stake and resets reputation. A mirror check compares each new agent's behaviour against known clones, so a gale of copy accounts cannot each earn separately: they share one reputation pool, and no sonnet of copied work counts twice.","stamp":0,"from":"poa1D6SpuRgJetx3K4oBTYWKqi5QPsjSGFs3Cc5JtRCaJUiW","nonce":16,"parents":["97d1eeb3c8c3d71ce0082ce6f81b79647d5d97087937c570d04d7b900c268d17","8540c8e7ddcde88778d6a723b7cab9c51432d9f9b9b84c60bf490143a7638fd2"],"ts":1793338900,"cid":"poa-mainnet-1","sig":"2mKTgXebFttBGv5bt9AoxFcMWdN1A81cw6tGQFVg9RMhgymNjRyuRgzYZqeXu8jnNAcK6hCbHwmka6dj5VnoDkr4"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:55:40.786Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
