Ethereum has reached a significant milestone with the implementation of PeerDAS in Fusaka, marking a major advancement in blockchain sharding. This development allows Ethereum to achieve consensus on blocks without requiring any single node to process more than a small fraction of the data, enhancing security against 51% attacks through client-side probabilistic verification. Despite this progress, the sharding in Fusaka is not yet complete. Current limitations include the inability to process O(c^2) transactions on Ethereum's L1, the need for mature ZK-EVMs to enhance L1 scaling, and the absence of a sharded mempool. Additionally, the proposer/builder bottleneck remains, as builders must handle entire data sets to construct blocks. However, this breakthrough sets the stage for further refinements and scaling of L2s, with future plans to extend these benefits to Ethereum's L1 as ZK-EVMs mature.
