Hegota Upgrade Marks End of Pre-Lean Ethereum, Paving Way for Network Rebuild
Ethereum's Hegota upgrade marks the end of pre-Lean Ethereum, according to Vitalik Buterin. This major network overhaul aims to replace key components and achieve quantum safety.
The Lean Ethereum effort includes replacing how transactions are confirmed, data storage, and achieving quantum safety through a new design for blobs to protect Layer 2 networks. Hegota is the second upgrade of 2026, with a proposal deadline of October 4, 2026, and a selection date of November 3, 2026.
The PFI deadline passed on August 6, 2026, while the CFI deadline arrives on December 10, 2026. The roadmap also includes a large gas limit increase in the Glamsterdam upgrade to provide more room for transactions in each block.
