最新报道：According to a report by Bijie.com, Ethereum founder Vitalik Buterin stated in a post on the X platform that security is paramount for Fusaka. Its core feature, PeerDAS, attempts something unprecedented: creating a real-time blockchain that doesn't require any single node to download all data. PeerDAS works by requiring each node to request only a small number of "chunks" to probabilistically verify that more than 50% of the blocks are available. If more than 50% of the blocks are available, then the node can theoretically download those chunks and use erasure coding to recover the remaining data. In the first version, the complete block data still needs to exist in one place, in two situations: (i) Initial broadcasting: when the data is first published; (ii) Data reconstruction: when the publisher has published between 50% and 100% of the blocks. However, these roles are trustless: only one honest participant is required to perform these tasks; even if there are 100 dishonest participants, the protocol will bypass them. Furthermore, different nodes can perform this task for different blocks. In the future, cell-level messaging and distributed block building will allow both of these features to be distributed as well. This is all new technology, and the core developers are wise to be extremely cautious in testing, even though they've been working on it for years. This is why the initial increase in blob size will be conservative, then more aggressive over time. But this is key to L2 scaling (and ultimately L1 scaling, once the L1 gas limit becomes so high that we have to put L1 execution data in blobs).
