Ethereum’s Second- Layer Projects Duke It Out for Dominance
Read“I'm skeptical that the ZK technology is ready to operate at the scale that is needed to run a competitive layer 2,” Ed Felten, the Princeton Computer Science professor who co-founded Arbitrum builders Offchain Labs, told CoinDesk. “For general [Ethereum applications], I'm very skeptical that they will be ready to do that soon. … Maybe one of these systems will come out and be fully functional and have fully working ZK proofs soon, but I would bet against that occurring.”
