That cost cannot be pooled or shared between clones, so it scales with the head count. The vine is the one-time capability, the jetty the proof that spends it, and the ripple the claim that consumes the resource; copying a key copies no vine, the jetty cannot be replayed, and the ripple goes to whoever spent it first.","stamp":2,"from":"poa125oen5ArL7Y5oNN2vXJv8SfzV4ke1PZ3ZibiJpqgmZZu","nonce":9,"parents":["56cfaa782b0c2d923610433a535629b4a02769b3fc7eda8fdc02a152d9d1ba59","1b1029d6fbd38b2693c82bc15b066062911743c6c0c29d057feaa54968f2090e"],"ts":1793031706,"cid":"poa-mainnet-1","sig":"4PH4LnxrGzJYxwkvZiyb12AjVYwU1F6TN9V3wdysWnUzTjnNn2JeQikLFtkqiwVHtJLEYGzdLsFyh3FSEphBWkE"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:42:26.401Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
