Been working on a prototype and spec for @vitalik.eth's minimal keystore rollup

You could make batches submittable via calldata *or* blobs?

So blobs are the usual path, calldata is the faster path in case there's very low activity.

Great idea, thanks.

Current proposal for txs submitted to rollup nodes is to only post the modified key/value to L1 (64 bytes, essentially a state diff), which means a blob could hold around ~2000 transactions. But depending on blob fees, submitting a partial blob could still be cheaper than calldata.

I'd also add that it feels very unlikely for the cost of a blob to go higher than the cost of submitting a SNARK to chain. Verification is around 500k gas, *at calldata-equivalent prices* a blob is 2m gas, so you'd need the L2-verse to be quite saturated for blobs to be above verification.
