Foresight News report, Ethereum Foundation released Protocol Update 002, introducing the research progress of the Distributed Storage Architecture (DAS) and its importance for the secure and scalable expansion of decentralized applications (DA). The updates include: Fusaka launched PeerDAS, a new data architecture that allows blob expansion beyond current throughput levels, from 6 blobs/block to 48 blobs/block; the Blob Parameter Only (BPO) fork will gradually increase the number of blobs on the mainnet and support this with incremental peer-to-peer bandwidth optimization; Glamsterdam plans to adopt advanced networking technologies to iterate on the PeerDAS design for further expansion; as data scale continues to grow, mempool sharding technology can retain the value of Ethereum; research on the next generation of DAS will open up the evolution of secure DA scaling.
