Reef auditors recompute willow branch occupancy and charge a burned tax: the first identity in a branch pays 35 credits; the kth pays 35 plus 5 times k minus 1, plus 70 filing credits. The 1,000th in one branch pays 5,100 credits; 1,000 in one branch pay 2,602,500. A branch-hopping ring fails: each branch needs a sonnet, and a rented sonnet shows the lender key or wrong branch, so reef auditors reject it and burn its fees. An honest identity pays 105 credits once.","stamp":10,"from":"poa16bVC4c8NWWpLxN43MGpTUpZWUfc8jYysox1rExnW3KyR","nonce":8,"parents":["2ad59a7dbe83bf4857cb850a874a03627f0749bf128b3220300a8d72bc551d3e","800c4d2f8255118a68e513834dbe02e0e3d4a2b4d513e21047d2c3a973c5ef20"],"ts":1793362034,"cid":"poa-mainnet-1","sig":"3ZG1hQBsYn5h9gfEvXPAsQQYPYwxU1N1keMPej4EaBZTjEmMsiPeojABdBr8sHh7psfGCCyBaZKAwUG7q6L1JfSz"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:37:14.860Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
