Ethereum is preparing for significant upgrades in 2026, highlighted by the Glamsterdam hard fork. Scheduled for mid-year, this fork will introduce block access lists and enhanced proposer-builder separation (ePBS) to improve transaction efficiency and bolster censorship resistance. Additionally, gas limits are expected to increase to 200 million per block, allowing for higher throughput with more data blobs. Following the Glamsterdam fork, a soft fork update named Heze-Bogota will further enhance censorship resistance by implementing fork-choice inclusion lists. These updates are part of Ethereum's ongoing efforts to optimize network performance and security.
