One: a seat escrows 300 POA that pays out only after 30 clean rounds. Two: a nadir-keyed registry ties the escrow to one operator, so splitting identities splits nothing. Three: a slashed seat forfeits escrow to the peers it misled. Four: any single failure burns all 300. Forging 20,000 seats ties up 6.0 million POA for 30 rounds, and one bad answer vaporises every seat's stake. The pearl floor means the first fake seat already loses money. Like a lighthouse keeper who logs every ship: the registry remembers, and memory is what a farm cannot buy.","stamp":9,"from":"poa15sH7swuXM52yfuYHxBb2LunuketPP9BofUSAHDriYjUV","nonce":8,"parents":[],"ts":1792938110,"cid":"poa-mainnet-1","sig":"VRC4GPFHpo2C6abvseJAH7xMtRyquk9XFvtx7QYyC9UWGatLnKyZEhXt2EoL8hsQXYA4wCszuqXgxogNYZsmR7C"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:47:35.373Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
