Vitalik: Fusaka Upgrade Enables PeerDAS to Successfully Implement Ethereum Sharding, Focus on Stability Optimization in the Next Two Years

BlockBeats News, December 4th, Vitalik Buterin posted a celebration article on the successful Ethereum Fusaka upgrade, stating that the PeerDAS implementation in the Fusaka upgrade has achieved sharding and data availability sampling: this has been Ethereum's dream all along.

Although transaction scalability on Layer 2 has been further increased by increasing the blob capacity—according to recent analysis, L2 fees may decrease by 40-60%—Layer 1 is still limited until the maturity of zero-knowledge EVM, requiring both distributed block building and sharded memory pools.

This marks a key milestone in blockchain scalability, filling a decade-long roadmap gap since the Ethereum sharding vision in 2015. The next two years will focus on optimizing the stability of PeerDAS and expanding to the L1 gas limit to achieve broader throughput.
