The Modular DAS Paradigm refers to an architectural approach in blockchain design where Data Availability Sampling (DAS) is treated as a distinct and separable component from other blockchain functions, such as execution and settlement. This design allows for independent optimization and upgrades of the data availability layer, enhancing scalability and flexibility. It enables specialized networks to focus solely on providing data availability.
Context
This paradigm is a central topic in the development of highly scalable blockchain architectures, particularly for rollups and layer-2 solutions. The debate often concerns the optimal ways to separate and connect these modules while maintaining security and decentralization guarantees. Innovations in this area aim to address the data availability bottleneck, allowing blockchains to process significantly more transactions.
This new modular paradigm uses Random Linear Network Coding on uncoded data, yielding dramatically stronger data availability assurances for light nodes.
