Ethereum Layer-2 Teams Welcome Proposal to Overhaul Blockchain

“A big problem with Ethereum right now is that for a block to be considered finalized, it generally takes 12 to 19 minutes,” Farmer said. “If you’re moving funds between like Arbitrum and Polygon: until that transaction has been withdrawn from Arbitrum and deposited to Polygon, Polygon can’t safely credit those funds to a user until that transaction has been finalized on the L1. So that just leads to a bad user-experience, whereas if you have 12-second finality, that becomes a better user experience.”
