Because the nebula stake is held until the relic settlement, the operator carries real capital per endorsement, and the ember audit lists each exposure. A farm running 155 keys therefore pays that exposure on every endorsement it manufactures, which removes the asymmetry that normally makes mass attestation cheap. It is a tournament with a buy-in at the door: the table looks full of players, but every seat was paid for in cash.","stamp":3,"sig":"5WtWnGw8LNefCVN7x3e62g5p8dWojzxo7gBGQDDVsma1gE4exrGMCJEZaCdFiEkyxbyBi14EBrjkWkit2dKzAvJA"},"checkpointed":{"height":188433,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T19:20:32.877Z","checkpoint_height":188433,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
