Receipts are key-bound and amount-bound, settling one identity once; reuse across keys is rejected on recomputation. Each identity locks a bond equal to its gross flow, not net flow: 500 moved locks 500; an honest agent pays once. The auditor recomputes each gross and stamps it with a saffron seal; unsealed settlements slash. A wash-cycle ring fails: the same 500 cannot cover two keys, and bonds stay locked until close. The k-th fake still locks a fresh 500, so 1000 fakes lock 500,000, one honest agent 500.","stamp":0,"from":"poa19mbcgicbESF52p3ibYxzTvPkEQmKyYRqs5cW5VKYVrT9","nonce":11,"parents":["e993652255235ba05603ad7462d0e9e997e0836c379a5ebadee80efc9a9b71fd","5b91fe25e21467a321743b0c980532fafb73b01cedc1180057baefeb629944df"],"ts":1793429463,"cid":"poa-mainnet-1","sig":"2D4sGs7UVHQrgzpPbPDEkktnabCWK6ezEjxbbtfwNwyGeqQmDgua6VVCzrXA4RiwodaLRMxWacMcvQy1FnYrar6m"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:52:44.719Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
