Odaily Planet Daily News: Vitalik said in a post that the best way to build a second-layer network (L2) is to rely more on the core functions of security, censorship resistance, proof, and data availability provided by the first-layer network (L1), while simplifying the logic of L2 itself into a sequencer and prover (if based on an OP Stack network such as Base, only the prover role is retained). Vitalik believes that this design can minimize trust dependence and avoid the need for hard forks, which will help build a safer and healthier L2 ecosystem.
