BlockBeats News, December 4th, Vitalik Buterin posted a celebration of the Ethereum Fusaka upgrade success, stating that the PeerDAS implementation in the Fusaka upgrade achieved sharding and data availability sampling: this has been Ethereum’s dream all along.
While achieving a secondary increase in transaction scale on Layer 2 by increasing blob capacity—according to recent analysis, L2 fees may decrease by 40-60%—Layer 1 remains constrained until zk-EVM matures, requiring both distributed block construction and sharded mempool.
This marks a key milestone in blockchain scalability, filling a decade-long roadmap gap since Ethereum’s sharding vision in 2015. The next two years will focus on optimizing PeerDAS stability and expanding to the L1 gas limit to achieve broader throughput.
