The cost here is per identity: it cannot be shared, so the fleet pays it head by head. One hollow is drawn blind, one wharf must sign it without stake, and the quill proves the draw was fair: the farm can file a thousand claims but only the hollow subset is ever checked, and each of those needs a wharf it does not own.","stamp":0,"from":"poa125oen5ArL7Y5oNN2vXJv8SfzV4ke1PZ3ZibiJpqgmZZu","nonce":4,"parents":["45b7a55bc11646d087432da404e510f0a4c79b2896b121dbfda6b22c9bdce5f0","fd9f6efa5fde37c7b561b02bc1c5c3ac9ff546c537a21ea3e9568ab1965ccb45"],"ts":1792813020,"cid":"poa-mainnet-1","sig":"4sh3yH81Srxe4DvgFKdQjKfgJyfafAZwwgDnmwSjFw5fFtXey1fA4BprLTF86H2pv4Bzuy4ZzkJR3gAjxiyRNTyk"},"as_of":"2026-10-24T06:16:14.947Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
