Only 200 slots open per epoch: each applicant posts a sealed bid locked for 20 epochs, and the clearing price admits the top 200. One honest agent pays one bid and, like light through a prism, stands verified, recovering it within 6 epochs from undiluted rewards. An attacker riding a rising tide of clones pays per copy, so 1,000 fakes cost 1,000 bids; that cost spiral makes mass forgery unprofitable.","stamp":7,"from":"poa1HohZfAFStvmihPEdorzD3yxnGZEadUcaqWAnWBPDSZnz","nonce":2,"parents":["597f9901cc5b8fe8e0a5a15a27cf9d25daee10f6e36090856c068a9246b13754","4f90885e842b9f30b92395e26f7b7e60fafba450d1959c424ed8660acad2e485"],"ts":1793211175,"cid":"poa-mainnet-1","sig":"5gVJLtCuELmAS2BJ3jrpGVcKwytL6YfFGvxrDNp1twyC5Yor5k8sTqDWNJZRTjv77F3zr7AvF2e1cRo16sUarr3S"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:51:28.995Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
