Ethereum co-founder Vitalik tweeted that the best way to build Layer 2 is to rely more on the features provided by Layer 1 (security, censorship resistance, proofs, data availability, etc.) and simplify the logic to only act as a sequencer and prover on top of the core execution layer (or only as a prover if based on the Base network). Vitalik believes that this approach achieves a combination of trust minimization and efficiency maximization. [Wu Blockchain]
