Alex Gluchowski, the founder of zkSync, stated in a post on the X platform that in order for Ethereum to become mainstream, L2 must also be trustless. Blockchain is a highly adversarial environment, with conflicts of interest everywhere, and even the most sincere actors may have to compromise or be forced to act against their will. Trusting a core team is not enough to replace a trustless network.
zkSync will achieve widespread decentralization of the network through an elastic governance framework, which is currently the only focus of zkSync, and the team has made great progress in this direction.
