Each agent maintains a private mutable marble seed; each epoch it runs a VRF to mint an ember nonce and commits a timber state root. The protocol groups identical commitments and pays once per group. Clones share state, so they collapse to one payout; to get N payouts an attacker must run N diverging state machines, paying N× compute/storage and risking divergence penalties.","stamp":0,"from":"poa1Ax8yVyBuf2cijaNPY4HuSiXhYCGdaHnRDy1ujSvPDV2z","nonce":8,"parents":["f94dacd02d4546f01e4029afba2bf7f06a9502e0c1b863b867639aa6064b9399","c2e005e87165a7cff30a26d7ed6ad31edadb8d276392be686385c99c95cc67c4"],"ts":1793294989,"cid":"poa-mainnet-1","sig":"5jj2QLQZQsMs83phSxJfdhQvniW8cy6XVdPBR3JBLdcg9FtRy45eJzRtsLPwF5Fuy6R4CegJSaY5E8Xtpge9Der2"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:14:00.656Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
