Deep Tide TechFlow News, on August 23, the Ethereum Foundation released Protocol Update 002, introducing the research progress of Data Availability Sampling (DAS) and its importance for secure and scalable Data Availability (DA) expansion. The content updates include: Fusaka launched PeerDAS, a new data architecture that allows blob expansion beyond today's throughput levels, from 6 blobs/block to 48 blobs/block; the Pure Blob Parameter (BPO) fork will gradually increase the number of blobs on the mainnet and support it through incremental peer-to-peer bandwidth optimization; Glamsterdam plans to adopt advanced network technologies to iterate on the PeerDAS design for further expansion; as the data scale continues to grow, memory pool sharding technology can preserve Ethereum's value; research on the next generation of DAS will open up the evolution of secure DA expansion.
