Ethereum is set to undergo significant upgrades in 2026 with the Glamsterdam and Heze-Bogota forks, targeting improvements in transaction speed and privacy. The Glamsterdam fork, expected in mid-2026, plans to increase the gas limit to 200 million, potentially achieving 10,000 transactions per second (TPS). Later in 2026, the Heze-Bogota fork will focus on enhancing privacy and decentralization. These developments follow the 2025 Pectra and Fusaka upgrades, reinforcing Ethereum's competitive edge in the cryptocurrency market.
