glamsterdam

The Ethereum Foundation issued a reminder that the Glamsterdam upgrade will include adjustments to Gas fees (EIP-8037 and EIP-8038), involving changes to the costs of state creation and access. Most contracts will not be affected, but some contracts that rely on hard-coded Gas values and other old assumptions may need to be updated; otherwise, they may fail or experience performance degradation.

According to CoinMarketCap, the Ethereum Foundation has allocated a total of $5.5 million in grants in the second quarter of 2026, covering areas such as ecosystem development, research related to zero-knowledge proofs, and security audits.The related grant arrangements aim to support the upcoming Glamsterdam upgrade, focusing on strengthening network infrastructure and technical security capabilities, and continuously promoting the development of the Ethereum ecosystem.

The Ethereum Foundation (EF) warns that changes to the Gas model in the Glamsterdam upgrade may cause some wallets, indexers, and Gas estimation tools to become ineffective. The EF Protocol DevOps team stated that tools relying on hard-coded maximum Gas limits will fail, and developers need to update relevant systems and test on the Plataberget public testnet.Plataberget went live on August 13 and is planned to run for several months. The Glamsterdam fork is scheduled to activate on the Ethereum network on Thursday, followed by deployment to the Sepolia and Hoodi testnets. EIP-8037 will introduce an independent state Gas dimension for operations that create new states. Transferring ETH to existing accounts will still require 21,000 Gas, while transferring to new accounts will incur additional state Gas; developers should also re-evaluate software that considers 21,000 Gas as the total cost for all ETH transfers or only uses a single Gas dimension to estimate transaction fees.

The Ethereum Foundation's DevOps team announced the launch of the Platåberget testnet as an early public testing environment for the Glamsterdam (Gloas + Amsterdam) upgrade. This testnet is open to the community and is planned to run for several months, providing developers with a stable experimental platform to identify and fix issues before the upgrade is deployed to long-term testnets like Sepolia and Hoodi. The Glamsterdam hard fork is scheduled to activate on August 20 on this testnet.The Glamsterdam upgrade includes several significant changes to both the consensus layer and execution layer, including built-in proposer-builder separation (ePBS), block-level access lists (BALs), gas repricing targeting approximately 200 million gas, an increase in the maximum contract deployment size from 24KiB to 64KiB, an increase in the initcode limit from 48KiB to 128KiB, and forward-compatible consensus data structures. Relevant EIPs are summarized in meta EIP-7773. Gas repricing will affect wallets, indexers, and gas estimation tools, and any tools with hard-coded maximum gas limits will need to be updated; EIP-8037 also introduces an independent state gas dimension, where new accounts or writing to new storage slots will be charged by state bytes.The Platåberget validator set is small and allows public participation, supporting deposits from validators or builders submitted through the Dora browser. The testnet provides one-click resources to add networks, faucets, and client images. The community can provide feedback on issues in the Ethereum R&D Discord and related specification repositories.

Ethereum core developer Terence posted on the X platform that the Ethereum Glamsterdam devnet-6 has been released, and significant progress has been made in the testnet. EIP-8282 introduces ePBS builder execution requests, which include two new system contracts. On the execution layer, based on the work from post-bal-devnet-7, EIP-2780, 8038 (repricing), 7997, 8246, and 8070 (optional) have been added, and modifications have been made to EIP-7954 (64 KiB), 8037 (source-based refunds), and 7928 (BAL×7702 preheat maintaining status quo).

The Ethereum Glamsterdam hard fork entered the final development testnet phase on Tuesday, locking in ten EIP proposals, positioned as the largest protocol upgrade since the merge.The two core proposals are: EIP-7732, which directly writes the proposer-builder separation (ePBS) into the consensus layer, replacing the current reliance on off-chain relays like MEV-Boost; and EIP-7928, which introduces block-level access lists (BALs), allowing validators to process unrelated transactions in parallel. The combination of these paves the way for a 200 million Gas limit, increasing approximately three times from the current level of about 60 million, with theoretical throughput reaching around 10,000 TPS.On the user side, EIP-2780 is expected to make standard ETH transfers up to 71% cheaper. The mainnet activation date has yet to be determined and must first complete validation on the Holesky and Hoodi testnets. Based on historical rhythms, it is expected to go live between September and December 2026. The 200 million Gas limit is a design goal rather than a fork-enforced value, ultimately to be gradually increased by validators through Gas voting signals.

According to CoinDesk, Ethereum developers have entered the final development phase of the Glamsterdam upgrade, running a developer network (devnets) that includes all planned EIPs, which will then be deployed to the public testnet. Parithosh Jayanthi, a core developer at the Ethereum Foundation, stated that this is the final stage before codebase hardening and testnet launch, and although there is no fixed timeline, significant progress has been made. Glamsterdam is expected to launch on the mainnet in the second half of this year and is described as "the largest upgrade since the merge," which will change many assumptions about Ethereum and lay the groundwork for larger-scale expansions in the future.Key features include EIP-7732 (built-in proposer-builder separation), which incorporates a separation mechanism for block construction and proposal into the core protocol to reduce MEV manipulation opportunities; and EIP-7928 (block-level access lists), which allows blocks to declare in advance the accounts and contract data they will access, improving execution efficiency. Glamsterdam also includes a series of gas repricing that will significantly change the operational costs on Ethereum: high-computation operations will become cheaper, while state management costs will increase.

The Ethereum Foundation has appointed three new co-leads, Will Corcoran, Kev Wedderburn, and Fredrik, to lead the main protocol cluster. The team handover work is now fully underway. The focus for the future is to release Glamsterdam, continue preparations for Hegotà, and advance Strawmap.

The Ethereum Foundation disclosed the results of a recent interoperability meeting held by core developers in the Svalbard archipelago of Norway and updated the key technical progress for the next phase upgrade, Glamsterdam. During the meeting, multiple client teams collaborated on network scalability and execution layer optimization, making progress in several directions. Developers confirmed that based on the comprehensive results of ePBS, BAL optimization, and the EIP-8037 repricing mechanism, a consensus on the "trusted path" after Glamsterdam has been reached.In terms of the execution layer, ePBS (External Proposer Separation Architecture) has been stably running in the multi-client Glamsterdam-devnet, and the external block builder process has completed end-to-end testing, covering almost all client implementations. Meanwhile, EIP-8037 has been finalized, establishing the fixed cost_per_state_byte model, and complete repricing parameter output has been achieved in bal-devnet-6. The scalability direction Hegotá has also made progress. The FOCIL-related prototype has a runnable implementation, and the scope of account abstraction (AA) requirements has been defined, with the next phase entering the multi-client development network verification stage.Current development focus remains on the final implementation of Glamsterdam while advancing the Hegotá scalability design and subsequent Strawmap route evolution. The development network is online, and functionalities such as FOCIL are expected to continue deepening in the next phase of testing. At the organizational level, this interop meeting also marks the formal initiation of leadership structure adjustments within the Protocol Cluster. The new leaders include Will Corcoran, Kev Wedderburn, and Fredrik. Will Corcoran is responsible for zkVM proof and post-quantum consensus coordination, Kev Wedderburn leads zkEVM development, and Fredrik is in charge of protocol security and the Trillion Dollar Security project.Original Protocol Cluster leadership team members Barnabé Monnot and Tim Beiko will gradually step back from management roles, and Alex Stokes is entering a leave period. The foundation stated that during its term, the Protocol has completed modular advancement and facilitated the launch of the Fusaka upgrade (December 2025), introduced PeerDAS, and enhanced mainnet gas capacity.

The Ethereum Foundation published a summary of the Soldøgn Interop work, which has now basically completed the key goals of the Glamsterdam upgrade, including reaching consensus on the post-upgrade 200 million Gas Limit lower bound, achieving stable operation of the ePBS external Builder process, and finalizing the EIP-8037 Gas repricing parameters.The focus of the Glamsterdam upgrade is to enhance security by increasing the Gas Limit to expand Ethereum's throughput, while EIP-8037 will prevent state bloat caused by a high Gas Limit by raising the cost of state creation. The Ethereum Foundation also stated that most clients have completed stable operation on glamsterdam-devnet-2 and successfully tested the entire external Builder process. Additionally, substantial progress has been made on FOCIL, native account abstraction, and Hegotá upgrade-related features. In the coming weeks, core developers will continue to advance client hardening, testing improvements, and code merging, with final parameters to be publicly confirmed in the AllCoreDevs meeting.

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.
