Soneium: Soneium is an ethereum L2 launched by tech giant Sony, which is built primarily on the Op Stack and will also join Optimism's Superchain network. From the limited information available, the overall architecture is expected to be not much different from Optimism, with DA relying mainly on the main Ether network, but indexing is perhaps mainly controlled by the project team, and details such as execution and settlement are not yet clear. Currently after more than half a month of development, the eco-project has taken shape with more than 60+ projects, and the collaborative applications will focus on entertainment, Web3 games and NFT services. In terms of project vision, the main goal is to utilize Sony's global distribution channels and capabilities in We2 to bridge Web2 and Web3, while it is relatively clear that Soneium plans to develop a Story Protocal-like feature to protect creators' intellectual property rights.
