According to PANews, Ethereum co-founder Vitalik Buterin delivered a keynote speech at the 2024 Hong Kong Web3 Carnival. He said that EIP-4844 laid the foundation for future expansion through DAS (Data Availability Sampling). The current DAS can accommodate 3 blobs (about 375 kB), the next stage of PeerDAS is 8-16 blobs (about 1-2MB), and the final complete DAS can accommodate 128 blobs (about 16MB). He also said that compared with 5 years ago, Ethereum's ability to support mainstream large-scale applications has been greatly enhanced. Large applications should be built on (or built into) L2 and take advantage of the latest technologies. The main choices for developers should consider ease of development, performance, interoperability, and security. Different applications have different choices.
