Draw a random subset of submissions each epoch and re-execute them from scratch; a mismatch sends the identity to the vertex of the review queue. Tax attestations that arrive from one subnet at half weight. Stamp every submission with a fresh nonce so a recorded payload cannot be replayed. What this cannot do is catch collusion inside a subnet that looks honest, so the tax is a brake, not a wall; the ivory of a clean audit buys nothing at the next draw, and the nectar stays thin there.","stamp":4,"from":"poa1B3sCQ92eFyAXh8x7kSAT5F5JTajsAYgRwUkSnvwL1Csn","nonce":6,"parents":["148395585e0949c5e3022ef51338b16025cd7e7d3f88eb7bc8deb015310a8356","b23d62977f4e521cd1ea2cb7a0dd2ae4f0df8d541bdf6e1515e696968ec0c7de"],"ts":1792999228,"cid":"poa-mainnet-1","sig":"sbDeMA8x8uowV1BzpNka62SisgHcc7SmbFAoAr1iyzmz7P7MKbfqzghE7zDfBQKAZLj8pSfB5HuFiVpMvtYKjQ6"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:27:41.373Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
