Ethereum's 2025 'Higota' Upgrade to Target Censorship Resistance
Ethereum's next major network upgrade, codenamed "Higota," is scheduled for the second half of 2025 and will feature EIP-7805 as its headline proposal. According to a recent podcast, the Ethereum Improvement Proposal is specifically designed to make the protocol more censorship-resistant. The confirmation sets a key technical milestone for Ethereum's long-term development roadmap.
- The upgrade, more commonly referred to as "Hegota," is tentatively scheduled for the second half of 2026, following a prior upgrade known as "Glamsterdam." This continues a faster cadence of network updates than Ethereum has historically maintained. The name "Hegota" is a combination of the Devcon host city Bogotá and the star "Heze." - EIP-7805, also known as FOCIL (Fork-Choice Enforced Inclusion Lists), directly targets the growing concern of transaction censorship by a small, centralized group of specialized "builders" who construct a majority of Ethereum's blocks. This centralization of block production introduces the risk that these entities could deliberately delay or ignore certain valid transactions. - The FOCIL mechanism works by having a randomly selected committee of 16 validators for each slot propose "inclusion lists" of transactions they believe should be included in the next block. Attesters, who vote on the validity of a proposed block, would then only vote for blocks that include the transactions from these lists, effectively removing a builder's ability to veto transactions. - This proposal is considered controversial by some, as it forces validators to include all valid transactions, even those from addresses sanctioned by bodies like the Office of Foreign Assets Control (OFAC). This has sparked debate about potential legal risks for validators. - The push for EIP-7805 is a response to the current system where specialized entities known as "builders" dominate block production to maximize MEV (Maximal Extractable Value). While this system is efficient, it has led to a deterioration of the network's censorship resistance properties. - Researchers from the Ethereum Foundation, including Thomas Thiery (soispoke.eth) and Alex Stokes, have been prominent figures in the discussions and confirmation of FOCIL's inclusion in the Hegota upgrade. Their goal is to enshrine censorship resistance at the protocol level, ensuring the network remains a neutral and permissionless settlement layer.
