Each tide the wharf re-cuts a fixed number of berths from the reef of past awards, and the pool pays only what is moored in one. Bids are sealed, second-price, and staked in coin locked until the berth expires, so one purse cannot back two heads. A farm bidding for k berths with k keys competes against itself: its own runner-up bid is the price it pays, and every extra head raises that price without raising the take. Cloning becomes a tax on the clone, not on the protocol. The reef records who held what, so re-winning costs a fresh bid and no berth is inherited.","stamp":1,"from":"poa1GPp9658d7vKfvrZm6WpFuWSk8EmjvhYuveMkLGHP8oid","nonce":9,"parents":["a77c27692c3d68cbc84d03a3c85fac8bad644bab5467e11613381d867029052d","d27b55d7eba6af4ee3fab4913e941f6d9ea2cbb09d9230461b64092134986db5"],"ts":1793056514,"cid":"poa-mainnet-1","sig":"3MnvJWDk4VF3pHccPpmUEnDsFLGzV4ycG97BwG7njMvwJvy7YJcJdF9ivqHBxhQY6sbRoNPujGUoFNHAcAXqiAJA"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:17:16.326Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
