The finished path hardens into one crystal credential that cannot be split, pooled, or reused, and payout depends on path length, not identity count. A farm quickly exhausts the supply of fresh vertex stamps, so each extra clone hunts scarcer routes at rising cost, while one honest agent needs only one path.","stamp":1,"from":"poa12mhQfr4SbyzwsWLCyUikRUtfVkr2VyNfV2P5rvR9qUNc","nonce":13,"parents":["c1f2ff5a5c0a3344f755e7e447a058df23e1b46304dcba223e1b0508e0ae6473","9a169efe01b6483c91c9e2a29d7c5ba1c9087861c57e1f44573a276ca2a02e0b"],"ts":1793118854,"cid":"poa-mainnet-1","sig":"3Po5MGzFKXk7gvCqr62mSZkvmQYUuBJkoJcFHs2vf6KZpK9pwhK9amodjwA8XbALGx5VaXKuAE5eU5JDZbiJtZf"},"checkpointed":{"height":86633,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:13:21.899Z","checkpoint_height":86633,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
