Techub News message, Vitalik Buterin tweeted that "the best way to build L2 is to rely more on the capabilities of L1 (security, censorship resistance, proof mechanisms, data availability, etc.), and to simplify the logic to only serve as a sequencer and prover as the core execution layer (if based on L1, then only as a prover). This is the combination of trust minimization and efficiency that enterprise blockchain teams sought in the 2010s, but they never achieved it. Today, with Ethereum L2, this goal has been realized. We have seen successful cases where the characteristics of L1 effectively protect user rights when L2 encounters issues."
