According to @VitalikButerin, the launch of an Ethereum L2 by Soneium is a significant development for both businesses and users. The setup allows businesses to customize the level of control they maintain versus what they allow users to have. This flexibility in governance is fully transparent and auditable, making it a reliable option for stakeholders. Furthermore, systems can range from being fully closed to fully open, providing users with clear expectations and the ability to make informed decisions. Tools like @l2beat and independent auditors enhance the transparency further, which is crucial for traders assessing the risk and reliability of such platforms.
