No, just one block with unavailable TxObject data.
Isn’t this preferable? Censoring committees should be the least profitable.
Provers (like block-builders) will centralize on price regardless. The worst-case impact on liveness is the time it takes to predict a profitable opportunity [1].
A MIN_PROVER_TIME can also be set to make decentralized compute competetive [2].
You could add epoch-sized-proofs to Re-Based by letting the bonded prover post TxEffects over time (with MAX_PROOF_TIME == EPOCH_TIME). This would sell epoch-building rights at the bond price, and remove parallel block proving.
