Ethereum Foundation researcher Thomas Thiery has recently proposed adopting the FOCIL (Fork Choice Inclusion List) mechanism as the core feature of Ethereum’s second major upgrade in 2026—"Hegota."
The Hegota upgrade is expected to launch in the second half of 2026 and is set to be far more technically complex than previous updates. This upgrade aims to introduce FOCIL’s anti-censorship capabilities to address the growing risks posed by increasingly centralized block builders. Additionally, it will tackle the persistent issue of "state bloat" through the implementation of Verkle trees and state expiry mechanisms.
Upgrade Background
Ethereum is undergoing a pivotal transformation from a "world computer" to a "global settlement layer." As network activity surges and adoption widens, two major bottlenecks threaten its long-term growth: infrastructure centralization risks and state data bloat.
According to the Ethereum Foundation’s technical roadmap, the Hegota upgrade is positioned as the next major protocol update following the mid-2026 Glamsterdam upgrade. The name "Hegota" merges the execution-layer Bogota upgrade with the consensus-layer Heze upgrade. Its core objective is to ensure Ethereum remains a vibrant decentralized platform for the next decade.
Technical Architecture of the Hegota Upgrade
The Hegota upgrade focuses on two main directions: enhancing censorship resistance with the FOCIL mechanism and addressing state bloat with Verkle trees.
On the censorship resistance front, FOCIL is proposed as the centerpiece of the upgrade. This mechanism empowers a committee of validators to forcibly include valid transactions in blocks, rather than relying solely on the decisions of individual block builders. By modifying Ethereum’s fork choice rules, FOCIL ensures that any valid transaction will be included in an on-chain block within a defined timeframe.
To solve state bloat, the Hegota upgrade plans to replace the current Merkle Patricia trees with Verkle trees. This change will significantly reduce proof sizes and enable stateless clients to verify the blockchain without the need for extensive local storage.
How the FOCIL Anti-Censorship Mechanism Works
FOCIL is intricately designed to fundamentally shift how transaction inclusion responsibilities are distributed. According to the technical specifications in Ethereum Improvement Proposal EIP-7805, FOCIL decentralizes power through a committee system. In each slot, a group of validators is selected as inclusion list committee members. Each member builds and propagates an inclusion list based on their subjective view of the mempool.
Validators play a critical role in the FOCIL mechanism. Within a specific time window, they receive, store, and forward inclusion lists, and stop accepting new lists after the view freeze deadline. Most importantly, validators only vote for blocks that satisfy the inclusion list conditions. This means any block that fails to include the specified transactions cannot garner enough votes to be considered part of the canonical chain.
ERC-8004 Standard and the AI Transformation
Parallel to the Hegota upgrade, the Ethereum ecosystem is actively embracing an AI-driven transformation. In January 2026, Ethereum contributors outlined the ERC-8004 standard, which aims to bring structured communication and settlement between AI agents to both the mainnet and L2 networks.
The core innovation of ERC-8004 is providing portable identity and reputation systems for AI agents. Each agent is assigned a unique on-chain identity, recorded as a non-fungible token (NFT). The standard also introduces an on-chain reputation layer, where ratings and feedback based on task performance and user experience are permanently stored on Ethereum.
For high-risk or sensitive workflows—such as financial operations—ERC-8004 supports verification mechanisms. The verification registry connects agents with independent validators, who can stake funds to rerun tasks or use technologies like zero-knowledge proofs to confirm that outputs match the agent’s claims.
Market Data and Investment Perspective
According to Gate market data, as of January 29, 2026, Ethereum (ETH) is experiencing a complex market landscape. The current price stands at $2,954.34, with a 24-hour trading volume of $473.57M and a market capitalization of $353.69B, representing an 11.30% market share. In terms of price movement, Ethereum has changed -1.37% over the past 24 hours, -6.18% over 7 days, and -0.3% over 30 days.
Looking at long-term data, Ethereum’s all-time high is $4,946.05, while its all-time low is $0.4329—demonstrating the asset’s extreme volatility. The current circulating supply is 120.69 million ETH, with the total supply the same and no maximum cap.
Market forecast models predict Ethereum’s average price in 2026 will be $2,926.98, with possible fluctuations between $1,990.34 and $3,834.34. By 2031, Ethereum’s price could reach $7,657.97, representing a potential return of +77.00% compared to current levels.
Ecosystem Impact and Outlook
The advancement of the Hegota upgrade and the ERC-8004 standard marks Ethereum’s multi-dimensional push to solidify its role as a globally neutral settlement layer.
The introduction of FOCIL directly addresses the growing centralization in the block builder market. In recent years, MEV competition and vertical integration among builders, relayers, and searchers have led to increased concentration. Researchers warn that this structural centralization poses inherent risks, even if large-scale censorship incidents remain rare for now.
On the AI ecosystem front, ERC-8004 has received broad support from contributors at MetaMask, Coinbase, and Google’s agent-to-agent protocol. Over 70 projects have submitted demos or built agent browser interfaces similar to blockchain explorers. L2 networks like Taiko have publicly backed ERC-8004, positioning it as foundational infrastructure for the anticipated expansion of the agent economy. Ethereum Foundation AI lead Davide Crapis describes the current phase as an early beginning, with February 2026 marking the "genesis" period for the standard’s ecosystem.
Ethereum Price on Gate market data is $2,954.34, while the median market forecast for 2031 stands at $5,209.50. Behind these figures lies a revaluation driven by technical upgrades. As AI agents begin to interact autonomously and build on-chain reputations via the ERC-8004 standard, network activity will enter a new dimension. The introduction of Verkle trees will lower the barrier for node operation, further reinforcing decentralization. On the technical roadmap, Ethereum is weaving a broader web—censorship-resistant mechanisms safeguard transaction freedom, state optimizations ensure network sustainability, and AI standards open new frontiers for applications. Every node in this web serves a unified goal: creating a neutral global infrastructure free from control by any single entity.
