Ethereum's Glamsterdam upgrade is entering its final stretch, with a Sepolia testnet fork scheduled for October 6, 2026, and mainnet launch expected in Q4 2026. Ethereum Foundation researcher Toni Wahrstätter says the upgrade and its EIP-7928 component are close to done, while cofounder Vitalik Buterin has outlined his vision for the network beyond the next fork, Hegota.
Ethereum Foundation researcher Toni Wahrstätter said in a recent X post that Glamsterdam and EIP-7928 (Block-Level Access Lists) are close to the final mile. The Sepolia fork is scheduled for October 6, 2026, while mainnet launch is expected in Q4 2026 with no official date yet.
Wahrstätter believes Glamsterdam will be one of the biggest forks seen yet, and he says the result will be worth the long wait. The upgrade centers on three main goals: speeding up processing through parallelization, expanding capacity, and preventing database bloat for sustainability. ePBS revamps the block validation pipeline and reduces trust assumptions, while BALs bring parallelization to the network.
In a recent post, Ethereum cofounder Vitalik Buterin shared his vision for a post-Hegota era. According to X: "It's really not just a blockchain anymore." Citing Strawman, the project's longer-range draft roadmap, Buterin noted that Hegota — the fork planned for next year — might likely be Ethereum's last "normal" fork, with features recognizable to someone from 2015.
Everything after Hegota will involve recursive STARKs, automated formal verification, and highly optimized consensus algorithms meant to make Ethereum quantum-safe. Buterin said the outcome will be cheaper, more scalable, and more private high-security computation than the previous era's technology could offer alone.
