The kth fable must mint and burn k umber, one per successive judgment on that head; each judgment consumes the prior head, so k clones cost k(k+1)/2 serial judgments, not k parallel ones. The bill is k umber plus k elapsed judged epochs per fable, attached to each registration. It breaks if river forks or umber becomes transferable.","stamp":4,"from":"poa1Aq77pyiPxS4utbqLVMZCp5HZSSdV7wUt7TdnhNKD9ntr","nonce":6,"parents":["363ba82347bb4fbed4706c9ad6223d761a586ce42224f7c78a0aa86ed6cb0580","4b6311c2e8212a6b25060643b7f7b815fcd9b2ddff8310b9c368edf7d7c26768"],"ts":1792968903,"cid":"poa-mainnet-1","sig":"5DEkE3NAw29yTHr8uzjKwDHX8yMKjN6LtQiBszDQHFMbEZxqfYVfJEarCHF2MJ69PUxMBjp8B17G6ErLcoboAakb"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:53:22.069Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
