Protocol: EIP-4844

[iAmMichaelConnor]

We might not actually have time to write this section before the end of the year. It'll require detailed investigation into:

• how much blob space will be available;
• whether Aztec will be able to make use of that blob space;
• what data Aztec should use blob space for (vs traditional calldata space);

...and then figuring out the actual protocol details for how we modify the circuits to commit data into blobs, instead of sha256-ing it all like we do today.
