As the Web3 industry continues to evolve, modular blockchain is increasingly becoming a pivotal force in building the multichain world. Recently, Web3Caff Research published a comprehensive report aimed at delving into the seven dominant narratives within this field, revealing its core position in constructing the future multichain world. The study centers on Ethereum, delving into its scaling strategy based on Rollup and the demand for middleware layers such as data availability (DA), Rollup frameworks, shared sequencers, interoperability, ZK proof services, etc. The report broadens its perspective beyond Rollup frameworks and the DA layer, attempting to view the entire modular blockchain ecosystem from a more macroscopic angle, including components like Cosmos, BTC L2, middleware, and ZK proof services. This research not only provides a new perspective on the development of modular blockchain but also offers valuable insights into innovation and collaboration within the industry.
