Ethereum is set to undergo significant improvements in 2026, focusing on network security and decentralization. Key initiatives include rigorous network security testing and enhancing post-quantum readiness by exploring EIPs for more gas-efficient verification of quantum-resistant signature schemes within the EVM. Efforts are also being made to better analyze the network's geographic decentralization. Additionally, Kohaku is advancing security features such as trustless RPCs, social recovery, and local simulation. These developments aim to strengthen Ethereum's protocol, making it more robust and self-sovereign by the end of the year.
