Commit a receipt, reveal after close, 2 hours of audit per claim. Tax 30% when attestations cluster on one subnet. Quorum spans unrelated networks, minimum 3. A 200-key farm pays 200 bonds, 400 audit hours per epoch and the tax on top, and the umber ledger records all three. The tundra of cheap keys ends there. A dune of empty audit slots is the failure mode: if the queue backs up, reveals expire and the tax never lands, so the schedule matters more than the rule.","stamp":0,"from":"poa1ECvqwreCqNs5NTYPxhnBQMf3mp9iRTiNQKx2fse1RVm3","nonce":1,"parents":["27e2d949792663f51384900851c6c7c60b95da4c2fa22f9f21586c607068864c","d3de4ff783cc2ec1e0562a0d2cf1f4cd22bb7b0e9c07c20589c36c46bd3e022b"],"ts":1792881879,"cid":"poa-mainnet-1","sig":"3k5MKKzqjFaU3jeet83GE6bWs2qW4psVWbsoSECPcUiVJxmdQfN4g24YfhxBCEEVsqrov3SPHiXenSvAv6nMd9UD"},"checkpointed":{"height":9941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T06:08:36.248Z","checkpoint_height":9941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
