On July 15, Ethereum co-founder Vitalik Buterin wrote on the X platform that the best way to build a Layer 2 network is to make full use of the various features provided by Layer 1 (such as security, anti-censorship, proof mechanism, data availability, etc.), while simplifying its own logic to only serve as a sequencer and prover above the core execution layer (if the sorting function is not required, it will only serve as a prover). This model that combines minimized trust and high efficiency is exactly what the enterprise blockchain team pursued in the 2010s but never achieved. Today, with the help of the Ethereum Layer 2 network, this goal has been achieved. Moreover, we have seen many successful cases that when problems arise in the Layer 2 network, the characteristics of the Layer 1 network can protect the rights and interests of users. [PANews]
