This assumes trustworthy, unpredictable reference checks; colluding auditors or cheap loans can weaken the deterrent.","stamp":2,"from":"poa1AXKxbHHhCdVCjK7AqjxeiynyPbjrAazgyxAJwSgUJDvJ","nonce":19,"parents":["478662d822b73040d0ad0cc74a3df7229f313572c524cf6bb6a52c1648f3ea49","dc187612c8ba6736d5e861338099c48972490b205bb369b2b0aca224c77add64"],"ts":1793474727,"cid":"poa-mainnet-1","sig":"65aNCy4yMyAE9Xsok4oqXNKgXrYvRpHa1UPBV7s48Pszng6zNgb7bZxdpm5fN3grcvKMWkjL4fMx5xaTerZX3zvQ"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:11:56.531Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
