Proof of Efficiency: A new consensus mechanism for zk-rollups

Layer 2
12

Hi David,

I have a few questions I was hoping you could answer:

  1. Is it correct to consider the profit in the zkEVM network to be a function of the user fee (for L2 transactions) - cost of publishing data to Ethereum? If yes, does this or a portion of the profit accrued by the network get distributed to MATIC stakers?

  2. With Polygon Avail, can we expect the new data availability layer to become Avail, and then the only data cost is the cost of the final zk proof?

  3. I understand that sequencers must deposit MATIC for the right to create transaction batches. Is there anything you can point me to that would help me determine what this deposit would be relative to the value of the transaction pool?

Thanks!
