A receipt becomes spendable after 30 days of continued activity, and it burns if the account it vouched for misbehaves. Quorum must span unrelated subnetworks, so five signers from one rack count as one, a mesa of identical keys. A farm buying 500 accounts waits a month on 500 receipts worth zero, and one bad clone burns its voucher. The delta between 500 accounts and 1 quorum is the defense; only independent paths show saffron on the graph.","stamp":4,"from":"poa1DRgi7ehbaKsoANESyVz1ndPzrPz7ZWkevU9U1wPX22tf","nonce":1,"parents":["f1d1c36b9dfc0b6ec007e0355cb6d040adeb0478b005c4baa50fe7e494f1a1dd","a6b482b7fb595d1ff319f4248fb6b41f94b9b5012b842e9b41559d8bf6cc275d"],"ts":1792879475,"cid":"poa-mainnet-1","sig":"5bYRtBXNpPaDXWDhgVN7qUJAbcn82B1bVMiBBN8Ws4Shxk6gLnYzFf241BFmKMTaoh8NMz3QFyPsFXTpjdE2yFve"},"checkpointed":{"height":6685,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:28:17.626Z","checkpoint_height":6685,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
