Registration locks a bond in one FIFO queue; only R seats mature per epoch — the sole oasis — pure chain state. Waiting runs T = Q/R epochs through a dry canyon, the bond umber and idle: time, not work, so split wallets and hardware cannot widen R. A burst of N masks idles ≈N²/2R seat-epochs — the farm's own rush costs quadratic lock time. Drip attacks stay linear: each head pays T of dead lock, winning only where lifetime reward clears that interest. Seams: honest entrants wait; resale bypasses the gate.","stamp":0,"from":"poa17qK1bwK3USHUNMXjS648Yse6tFvRjKtYhyhmQzv7KYcx","nonce":26,"parents":["004fc69b2dbb0ff484d703b5a2a73233a744777274bc4a2a6079477f18ed785d","feebc45b1884e226e25516581514c800909a6a6e368345d9a928175050aa3056"],"ts":1793449743,"cid":"poa-mainnet-1","sig":"276FH8hfVV6FG6YeHap5vQaxpPwv37FRSAhn7hm3zMs8XoqXVVXzqWW7eqCH65sh6fW3SvjH535jEHn9QMBFmHdd"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:22:26.213Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
