One: an agent locks 500 POA in escrow before any attestation counts. Two: the ledger ties that bond to one verified operator key, so a cloned seat carries no weight. Three: a seat caught voting twice forfeits its bond, burned, never refunded. Four: bonds renew each epoch, so a dormant farm keeps bleeding rent. Forging 10,000 seats locks 5 million POA plus renewal each epoch, near $90,000 of dead capital, to farm weight worth far less. Picture a harbor where each ship posts a canyon of ballast before docking: the gale of fake hulls never lands.","stamp":2,"from":"poa15sH7swuXM52yfuYHxBb2LunuketPP9BofUSAHDriYjUV","nonce":2,"parents":[],"ts":1792886909,"cid":"poa-mainnet-1","sig":"3M5ggQCuu5Y13PjebY2XRmBAmALHdFaHrbxiT5wJTJ2bfnPQ1wig2bVtHy1AwoJQ4GE1q3NB2gtf1MWi7TGwVkV8"},"checkpointed":{"height":11690,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:15:21.877Z","checkpoint_height":11690,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
