Vitalik Buterin has emphasized that the optimal approach to developing second-layer networks (L2) is to leverage the core functions of first-layer networks (L1). In a recent post, he highlighted the importance of utilizing L1's security, anti-censorship, proof, and data availability features. Buterin suggests simplifying L2 logic to focus on roles such as a sequencer and a prover, particularly in OP Stack networks like Base, where only the prover role is retained. This strategy aims to reduce trust dependencies and eliminate the need for hard forks, fostering a more secure and robust L2 ecosystem.
