“A giant drawback with Ethereum proper now could be that for a block to be thought of finalized, it usually takes 12 to 19 minutes,” Farmer stated. “In the event you’re transferring funds between like Arbitrum and Polygon: till that transaction has been withdrawn from Arbitrum and deposited to Polygon, Polygon cannot safely credit score these funds to a consumer till that transaction has been finalized on the L1. In order that simply leads to a nasty user-experience, whereas if in case you have 12-second finality, that turns into a greater consumer expertise.”
