Testing for potential problems and using formal verification are deemed necessary by Vitalik Buterin before scaling Ethereum's Layer 1.
Energy costs required for creating proofs remain a barrier for wider participation in the Ethereum network.
Vitalik plans to increase the gas limit on Ethereum by ten to one hundred times to enhance the network's efficiency.
Vitalik Buterin highlights advancements in Ethereum's scaling and verification while emphasizing the need for further improvements for real-world implementation on the Ethereum main layer.
