Ethereum’s upcoming Fusaka upgrade is set for December 3, marking the network’s next big step toward scalability and efficiency. The upgrade will introduce 12 EIPs focused on lowering costs, improving security, and optimizing infrastructure for long-term growth.
A major highlight is the doubling of blob capacity through two follow-up forks in December and January. Since blobs handle off-chain data for rollups, this expansion should ease congestion and make layer-2 transactions cheaper. Fusaka also debuts PeerDAS, allowing validators to verify only parts of data instead of full downloads lowering bandwidth requirements and supporting smaller node operators.
Meanwhile, Ethereum’s validator exit queue has hit record levels, raising concerns about sell pressure. Developers argue that longer queues help maintain trust and stability. With Fusaka, Ethereum is laying the groundwork for broader adoption by scaling rollups, cutting user costs, and preparing for the next wave of demand.
