On July 15th, Ethereum founder Vitalik posted an article stating, "The best way to build Layer 2 is to make more use of the capabilities provided by L1 (security, censorship resistance, zero-knowledge proofs, data availability, etc.), and simplify your own logic to only handle core execution as a sequencer and prover (or just a prover if it's a based design).

This model combines 'minimal trust' and 'efficiency,' which is a goal that enterprise-level blockchain teams in the 2010s pursued but never truly achieved. Now, with Ethereum's Layer 2 solutions, this goal can be achieved. In fact, we have already seen some successful cases: when problems occur in Layer 2, the functions of L1 successfully protect the rights and interests of users."
