As the blockchain world rapidly evolves beyond the limitations of monolithic chains, a new architectural paradigm has taken center stage: the modular blockchain. This model, which separates core functions like execution, consensus, settlement, and data availability into specialized layers, promises to finally crack the long-standing scalability trilemma. While much attention is paid to fast new execution layers (rollups) and interoperability bridges, one foundational component is often overlooked by casual observers yet is absolutely vital for security and scalability: the Data Availability (DA) layer.
This is precisely where innovative protocols like @Walrus 🦭/acc are carving out an essential niche. Walrus is not building another smart contract platform; it is focused on providing a robust, high-performance DA layer. But what does this actually mean, and why does it matter so much for the future of Web3?
