Ethereum co-founder Vitalik Buterin recently published a series of technical articles discussing the future roadmap of Ethereum. In the latest article, he focused on analyzing the potential centralization risks in the block building pipeline and proposed solutions such as expanding the FOCIL mechanism and introducing encrypted mempools to enhance the network's censorship resistance.According to the plan, Ethereum will launch the Glamsterdam upgrade in the first half of 2026, which will introduce the enshrined Proposer-Builder Separation (ePBS) mechanism. This mechanism allows block proposers to outsource block construction to a permissionless open market, reducing the centralization risk at the staking level. However, Buterin pointed out that while ePBS can prevent the concentration of block building rights among a few staking pools, the block construction itself may still become concentrated among a few high-tier participants due to specialization and maximizing MEV, leading to a new trend of centralization.To address this issue, Ethereum developers plan to simultaneously launch the FOCIL (Forward Obligatory Commitment to Inclusion Lists) mechanism in the Glamsterdam upgrade. The initial version will randomly select 16 witnesses and mandate that specific transactions must be included in the block; otherwise, the block will be rejected. Buterin stated that even if block construction is controlled by a single malicious entity, FOCIL can still ensure that transactions cannot be completely censored.Additionally, Buterin explored the possibility of expanding the scale of FOCIL ("big FOCIL") and introducing encrypted mempools to further mitigate the issues of information asymmetry and power concentration in the block building process. Recently, Buterin has been vocal about topics such as the quantum resistance roadmap, execution layer improvements, and block building mechanisms, indicating that the core Ethereum development team is conducting systematic design and risk assessment for the next phase of protocol upgrades.

Ethereum co-founder Vitalik Buterin recently released the Ethereum scalability roadmap, which is divided into short-term and long-term strategies. In the short term, the upcoming Glamsterdam upgrade will introduce block-level access lists for parallel validation, while optimizing block processing efficiency through ePBS and launching an innovative multi-dimensional Gas model that separates "state creation" from "execution" costs.In the long-term plan, Ethereum will handle data at rates of up to 8 MB/second using PeerDAS technology and plans to gradually introduce ZK-EVM technology starting in 2026, expanding its application scope by 2027, ultimately achieving a highly scalable blockchain network validated through multiple proof systems. This move aims to enhance Ethereum's transaction processing capacity while maintaining decentralization and security.

Ethereum co-founder Vitalik Buterin posted on the X platform that Ethereum's scalability is divided into short-term and long-term parts.In the short term, the Glamsterdam upgrade will introduce block-level access lists for parallel validation, ePBS will allow a larger proportion of time slots for block validation, and gas repricing will ensure that operational costs align with actual execution time.The multi-dimensional gas mechanism will be implemented in phases, starting with Glamsterdam, where the "state creation" cost will be separated from the "execution and calldata" cost, with state creation gas not counted towards the approximately 16 million transaction gas limit. The EVM level will introduce a "reservoir" dimension mechanism, which will prioritize the consumption of dedicated dimension gas by default, and when insufficient, will draw from the reservoir. This will eventually transition to multi-dimensional pricing, where different dimensions may have different floating gas prices.Long-term scalability includes ZK-EVM and blob components. In terms of blobs, there are plans to continuously iterate PeerDAS, aiming to achieve approximately 8MB of data processing capacity per second, with future Ethereum block data directly entering blobs.The ZK-EVM aspect will be implemented in phases: by 2026, there will be a validator client supporting ZK-EVM, allowing about 5% of the network to rely on it; by 2027, this will expand to a larger proportion of a few nodes while advancing formal verification; once conditions are mature, it will transition to a five-out-of-three mandatory proof mechanism, ultimately continuously enhancing the security and formal verification level of ZK-EVM, and involving changes to VMs such as RISC-V.

According to official news, the Ethereum Foundation has released the 2026 protocol priority update, which indicates that it will advance along three tracks: scalability (integrating L1 execution with Blob scaling), improving user experience (focusing on native account abstraction and cross-chain interoperability), and strengthening the L1 layer (enhancing security, censorship resistance, and network resilience).Moreover, the Ethereum Foundation stated that it will continue to push the Gas Limit to 100M and above, promote ePBS and further Blob parameter adjustments, advance the zkEVM attester client, as well as work on censorship resistance and post-quantum security; the next major upgrade, Glamsterdam, is targeted for the first half of 2026, with Hegotá planned for follow-up later in the year.

According to a post by Christine D. Kim on platform X summarizing the 173rd Ethereum consensus layer core developer meeting, to launch the Glamsterdam upgrade before mid-year, developers may need to significantly scale down the upgrade.Although there has not yet been an official acknowledgment of discrepancies in planning and timelines, if issues do exist, they need to be resolved by the end of February. Key discussion points from the meeting include: if a compatible version of EIP-7732 cannot be achieved by the end of February, it will be considered for removal from Glamsterdam and postponed to a future hard fork; performance issues with nodes were discovered in the Consensys Teku client during mainnet stress testing, affecting progress; EIP-7928 requires clients to conduct a small-scale API review; the submission deadline for the Hegota upgrade Headliner EIP proposal is February 4; some client teams have completed preliminary work on the EIP-7688 library update.

According to the minutes of the 172nd Ethereum Consensus Layer Developer Meeting by ACDC, developers discussed the upcoming Glamsterdam upgrade and the next phase of the Hegota upgrade.Among them, EIP-8070 "Sparse Blob Pool" has been included as a candidate feature for Glamsterdam, and the second hard fork of Fusaka, limited to blob parameters, has successfully gone live on the mainnet, increasing blob transaction block space by 40%. In addition, the proposal window for the Hegota upgrade is now open, with a deadline of February 5. Relevant proposals must be published on Ethereum Magicians and presented at the developer meeting. The meeting also covered topics such as ePBS testing challenges, suggestions for consensus layer anti-censorship mechanisms, and optimization of the EIP governance process.

According to records from forkcast org, the 172nd Ethereum Consensus Layer Core Developer Conference (ACDC) mainly discussed: successful activation of BPO2, Blob Target increased to 14, Limit increased to 21; EIP-8070 (Sparse Blob Pool) confirmed to be included in Glamsterdam; the proposal process for the Hegota headline proposal has been opened.

According to Cointelegraph, Ethereum will undergo several major upgrades in 2026, including the Glamsterdam and Heze-Bogota hard forks, aiming to achieve L1 scaling and further application of Web3 technologies.The Glamsterdam hard fork is expected to be launched in mid-2026, focusing on "block access lists" and "built-in proposer-builder separation" (ePBS). The former will enable perfect parallel processing, allowing Ethereum to shift from a single-channel model to a multi-channel model, significantly increasing transaction processing speed; the latter will help improve block generation efficiency and provide more time for the verification of zero-knowledge proofs. Additionally, the Gas limit for Ethereum in 2026 is expected to rise significantly from the current 60 million to 100 million or even 200 million, while the number of data blocks may increase to over 72 per block, further supporting L2 protocols to process hundreds of thousands of transactions per second. It is anticipated that 10% of Ethereum network validators will shift to validating zero-knowledge proofs, paving the way for L1 scaling to 10,000 transactions per second (TPS). The Heze-Bogota hard fork at the end of the year will also focus on enhancing privacy protection and censorship resistance, further optimizing the Ethereum ecosystem. Previously, Ethereum developers named the subsequent upgrade of Glamsterdam "Hegota."

According to Coindesk, Ethereum core developers are advancing a major protocol upgrade named "Glamsterdam," scheduled to launch in 2026, focusing on addressing the maximum extractable value (MEV) fairness issues in the current network.One of the leading proposals for this upgrade is EIP-7732: Enshrined Proposer-Builder Separation (ePBS), which formally introduces the division of roles between Proposer and Builder at the protocol level, reducing reliance on centralized relays and external MEV infrastructure, thereby enhancing censorship resistance and fairness in the block production process.Another key proposal that complements this is EIP-7928: Block-level Access Lists, which allows blocks to pre-declare which accounts and contract data will be accessed, helping nodes to preload and reuse data more efficiently, making block execution faster and more predictable, and laying the groundwork for future scalability. The complete list of EIPs for Glamsterdam is still being finalized.

According to The Block, Ethereum developers have named the next upgrade after Glamsterdam "Hegota," which combines the execution layer Bogota upgrade and the consensus layer Heze upgrade. The Bogota upgrade continues the tradition of naming updates after the host city of Devcon, while Heze is named after a star.It is reported that the main EIP for Hegota will be finalized in February, while the development work for Glamsterdam (the first planned upgrade for Ethereum in 2026) is still ongoing.

According to Christine Kim's summary of the 171st Ethereum Consensus Layer Core Developers Meeting (ACDC), the main topics discussed in this meeting included: retaining trustless payments as a component of the embedded proposer-builder separation (ePBS) in the Glamsterdam upgrade, while formally removing the Fork Choice Mandatory Inclusion List (FOCIL) feature. Additionally, the Fusaka upgrade successfully launched on the mainnet on December 3, and the subsequent blob parameter hard fork was smoothly activated on December 9, with the network operating stably.The meeting also discussed proposals such as EIP 7688, 8061, and 8080, and plans to start planning the Heka upgrade in January next year, while considering replacing its star names with those that meet the International Astronomical Union standards.

ChainCatcher news, the summary of the 222nd Ethereum Execution Layer Core Developer Meeting (ACDE) by Christine Kim shows that regarding the Fusaka upgrade, developers have initiated a shadow fork of the Sepolia testnet in preparation for the Sepolia upgrade, which is still scheduled for October 14.The meeting focused on the follow-up upgrade proposal codenamed Glamsterdam, which is the next major network upgrade following Fusaka. For Glamsterdam, developers have planned three key changes: 1. Block-level access lists (EIP 7928), with a multi-client testnet expected to launch next week; 2. Gas pricing reform, including a storage tax mechanism (EIP 8032) aimed at curbing state growth through dynamic pricing; 3. A new opcode (EIP 7791) that supports converting Gas directly to ETH. Additionally, the meeting clarified the proposal deadline for Glamsterdam, which will be one week after the Fusaka mainnet date is determined. The Holesky testnet is confirmed to be deprecated by the end of this month.

ChainCatcher message, Tim Beiko summarized the 219th Ethereum Execution Layer Core Developers Meeting (ACDE), the main contents of this meeting are:Fusaka development network progress: Devnet 3 is expected to be completed today, the consensus layer team is fixing synchronization issues, and if all goes well, Devnet 5 will be launched;Decommissioning Holesky: Plans to decommission Holesky a few weeks after Fusaka is activated on Holesky, and a public post will be released to explain the timeline and migration guidance;Gas Limit: The goal is to reach 60 million before the Fusaka upgrade;Glamsterdam update: Future meetings will prioritize discussing client-requested PFI matters, etc.

ChainCatcher news, according to Cointelegraph, Ethereum core developer Barnabé Monnot recently discussed the EIP-7782 improvement proposal, which aims to reduce the block generation time from 12 seconds to 6 seconds. This plan is intended to be included in the Glamsterdam upgrade at the end of 2026. Technical adjustments include compressing the block proposal time from 4 seconds to 3 seconds and reducing the verification time from 4 seconds to 1.5 seconds, resulting in an overall savings of 6 seconds in latency.Analysis indicates that after the speedup, DeFi transaction confirmations will be more efficient, and the window for arbitrage opportunities will shorten, but it may put pressure on network bandwidth and low-configuration validating nodes. If successfully implemented, the Ethereum Gas limit is expected to triple, and the supply of blobs may reach up to 8 times the current amount. The proposal is currently in the early discussion stage and requires rigorous testing to avoid smart contract compatibility issues.
