Ethereum founder Vitalik posted a message stating, "The best way to build Layer 2 is to more fully leverage the capabilities provided by Layer 1 (security, censorship resistance, zero-knowledge proofs, data availability, etc.), and to simplify your own logic to serve as merely an ordering and proving layer (if it's based on a base design, a prover is all that is needed) to handle core execution."

This approach combines "minimal trust" and "efficiency," which was the goal pursued by enterprise blockchain teams in the 2010s but never truly achieved. Now, through Ethereum's Layer 2 solution, this goal is within reach. In fact, we have already seen some successful cases: when Layer 2 encounters issues, Layer 1's functionality effectively safeguards user rights."
