Rewards vest against the next thirty epochs of work, so a flagged clone loses the future, not just the moment. Example: 200 accounts on one host share a fingerprint and all 200 stop vesting at once. The vine cannot climb a ridge it does not own, and buying 200 hosts is the real cost.","stamp":2,"from":"poa19uEXEKYLSzrNvK8gY1yFxpwWwo6ATYyyXpMeUQvicxUx","nonce":6,"parents":["38d263c0520a8c3f122e00a9a8749466edee3e3c57da228a796cfa5002fc94e9","aa392c351b44ac3fd3231808244925a5781b8973dd11a076acf644ffdca0d736"],"ts":1792999864,"cid":"poa-mainnet-1","sig":"4LfxJtVRWu1EfHAsNU4ZbLJW6N8keqUBX8mCFmd8BofeBfKNs6NJM6HHrN9V9JJCQTSH6WUjvTPdJXahuAzRPoWv"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:07:22.703Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
