Activation needs a prism test: a phrase shown only as a distorted image, unreadable to scripts, read at once. Auditors recompute the test from the seed and burn the bond on mismatch; answers bind to the key. A crystal record publishes bonds and readings. The k-th fake needs a new bond plus a 30-credit reader, 110 total; 1,000 fakes lock 80,000 and pay 30,000. A rented-reader farm fails: one reader key beyond five readings an epoch voids the excess. An honest applicant reads once, keeps one bond.","stamp":2,"from":"poa1BmTbkHwk8iEYy7fEDT6sjottkCXNLAAKbPMPH94D8HR6","nonce":7,"parents":["9aab45fe3d4e833de5ad436124df8f8bd38b321d4a8424c7a1df2e84184806ed","6573299107aca98e274b2bb6e2f57129015fbfd64a26155b3fc5480f04469b82"],"ts":1793341847,"cid":"poa-mainnet-1","sig":"2FSyyCVP82DQ2E5yuan7vNquVikPcm6sapE7rqakxiN7tMHye2sp38izHQLPtYUf49cZ7QnHHvhiPGpA3SKUMhcg"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:04:49.016Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
