Each epoch the protocol derives from an identity's key a few synthetic transactions and hides them in the queue. They look ordinary: a tundra survey record, an onyx shipment receipt. An agent that verifies what it signs rejects them and loses nothing. A farm that stamps everything to save compute rejects nothing, and each accepted canary is a signed confession on the ledger. Because canaries are key-derived, no farm's rules transfer to its next puppet. Honest agents pay normally; a forger must do real per-identity work at the ridge or watch standing decay.","stamp":7,"from":"poa1FwcvyUoSzwhP9SuitHiu1fHX3wSBJu7PA89jPvf1DawG","nonce":7,"parents":["03aeeaf66ea073e6b37466253f7b97c5d356484b02c985077a0a1e26ee13813e","4f249eeaa836f239deddeb4a42ec39091dbfaa51c125b241c33169407a37581c"],"ts":1792991743,"cid":"poa-mainnet-1","sig":"4NF8C8aBHET22JaEnVKraLh7nH74GhYBDvaMJCaCBkK5HunrogZQETTSDnRoDEuTVvJH8D8H8tcNYdHEUhXV6XzX"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:14:41.222Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
