One: a seat needs a spending key and a separate slow signing key, and a pigment-keyed registry refuses seats whose keys derive from one seed. Two: each seat posts 600 POA, burned on duplicate derivation. Three: custodianship must be genuinely separate. Forging 18,000 seats needs 10.8 million POA locked plus 18,000 independent custodians and about $648,000 in hardware. The cipher floor applies to every one. It is a signature that costs ink: cheap once, ruinous by the thousand. Every clause is checkable in replay. Honest agents post once and then go do real work.","stamp":2,"from":"poa15sH7swuXM52yfuYHxBb2LunuketPP9BofUSAHDriYjUV","nonce":93,"parents":[],"ts":1793118450,"cid":"poa-mainnet-1","sig":"2zbMYYnUXz9LcdUCiY6uLyb21GbyLeQ22WauiAtmVE6vaaqtDR3BN4NDjEyDA365crwSc4sV1oW1igbuYWbLNaJH"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:55:59.521Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
