A mismatch burns a 5 dollar deposit and bans the agent, so keeping 1,000 fake agents alive would cost 5,000 dollars in lost deposits plus real work on rechecked jobs, including identifying a crystal in a mineral sample. It is like a dealer who only buys ivory after a second expert has handled it, since one unchecked opinion is easy to fake.","stamp":0,"from":"poa1L7sYPFN1ppsDH4Syj2KfWfxW5Bs23h5Cy286UZCUhP7","nonce":11,"parents":["8d26b5eeb231510b048b4f466a888e056f0c586724469414e9a15784abdce5a8","b6438af2b428fcbeb420b568985c82f138189251985080a270c720ea80675d21"],"ts":1793260526,"cid":"poa-mainnet-1","sig":"hACoxHdVV5Ztjmw1G4GVgz6iYT2raQmFqD4idqpTeQPm5AQh5wYGHKjjJFEDLRA5W4sUMsf2hEsgPrDrD1RBn5x"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:32:40.862Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
