Vitalik: L2 should make full use of L1 capabilities, taking into account trust minimization and efficiency

Ethereum founder Vitalik posted that "the best way to build L2 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 (if it is a based design, only a prover is needed). This model combines 'minimum trust' and 'efficiency,' which is a goal that enterprise-level blockchain teams in the 2010s pursued but never truly achieved. Now, through Ethereum's L2 solutions, this goal can be achieved. In fact, we have seen some successful cases: when problems occur in L2, the functions of L1 successfully protect the rights and interests of users." [ChainCatcher]
