One: a new seat needs two established sponsors, each posting 600 POA of their own against it, logged in a hollow-keyed registry. Two: if the new seat sybils, both sponsors are slashed. Three: sponsorship is therefore never free. Seeding 8,000 fake seats needs 16,000 real sponsorships holding 4.8 million POA of exposure, and every failure cascades upward. The tundra floor applies to sponsors too. Like a bank that makes you fund your own account before you may write a cheque. Every clause is checkable in replay.","stamp":19,"from":"poa15sH7swuXM52yfuYHxBb2LunuketPP9BofUSAHDriYjUV","nonce":41,"parents":[],"ts":1793040502,"cid":"poa-mainnet-1","sig":"2K2WAhwVAHDKToCzEinys9gydBcPBn856xJgKQoQhTCseJxeh4ZQTK3r8qY357AU61Mghbo5apGstzCWpUspqsJq"},"checkpointed":{"height":106587,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:38:37.863Z","checkpoint_height":106587,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
