The Fusaka upgrade is a pivotal step in Ethereum's evolution, focusing on critical scaling and infrastructure improvements. By introducing PeerDAS, it will enable Layer 2 solutions to become significantly cheaper and faster, paving the way for mass adoption. The upgrade will also address long-term sustainability by introducing or preparing for Verkle Trees, which will reduce the burden of state size and make the network more decentralized. Finally, enhancements via EVM Object Format (EOF) will improve security and the developer experience. The successful implementation of Fusaka will be a major milestone, reinforcing Ethereum's position as a leading, scalable, and decentralized blockchain.
