- The Future of Ecosystem Development at the EF
The Ethereum Foundation is significantly expanding and reorganizing its Ecosystem Development (EcoDev) efforts into four areas, aiming to grow the number of people using Ethereum and to strengthen its technical and social infrastructure. The first area, Ecosystem Acceleration, adds four new teams for enterprise relations, developer growth, app relations and research, and founder success, with long-standing members such as Austin Griffith joining Developer Growth. Ecosystem Amplification includes the Digital Studio, which replaces the ethereum.org team, along with Strategic Events, Ethereum Everywhere, and a new EcoDev Automation team. The remaining areas are Ecosystem Support, covering grants and co-funding, and Long-Term Ecosystem Unblocking, covering policy, institutional and academic work.
- Welcoming a new EF leadership structure
The Ethereum Foundation has announced a new leadership structure with Hsiao-Wei Wang and Tomasz Stańczak as co-Executive Directors, effective March 17th. Wang previously served as a core researcher at the Foundation for seven years and was a key contributor to the Ethereum beacon chain. Stańczak led the team building the execution client Nethermind, which the announcement says has grown into one of the largest in the Ethereum ecosystem, and he is in the process of transitioning out of his CEO position there. The Foundation says the pair will ensure Ethereum's growth advances core values such as open source, permissionless global collaboration, privacy and security.
- A new chapter in the infinite garden
Aya Miyaguchi announces she will step down as Executive Director of the Ethereum Foundation (EF) and become its President, a role that lets her continue supporting EF's institutional relationships and expand its vision and culture. She writes that the decision was made a year ago and frames EF's role as upholding Ethereum's values rather than controlling every domain, which she calls "subtraction" and "stewardship, not control." The post cites examples such as stewarding All Core Dev calls, promoting client diversity, supporting R&D interop retreats, and running Devcon, which she describes as a network of independent yet interconnected communities.
- Announcing Protocol Ethereum Foundation
Ethereum Foundation's Protocol Research & Development group is restructuring and renaming itself "Protocol," reorienting around three strategic goals: scaling the L1, scaling the blobs, and improving UX. The announcement says the changes aim to make the group more responsive and effective, and that some PR&D members will not continue with the Ethereum Foundation. Each goal now has named leads: Tim Beiko and Ansgar Dietrichs for scaling L1, Alex Stokes and Francesco D'Amato for scaling L2, and Barnabé Monnot and Josh Rudolf for improving UX. Dankrad Feist will serve as strategic advisor across all tracks, and the group is recruiting a UX Lead and a Performance Engineering Lead.
- Goerli is shutting down
Goerli, Ethereum's first multi-client testnet, is being shut down, and users and developers are told to migrate to Sepolia or Holesky as soon as possible. Client and EF testing teams will stop supporting Goerli in the coming months, and the Dencun upgrade will be its last network upgrade. Teams will begin exiting their validators either three months after Goerli's Dencun activation or one month after Dencun's mainnet activation, whichever is later. The article notes that Sepolia offers a stable, permissioned validator set for application testing, while Holesky is recommended for protocol-level testing and Ephemery for validator setup testing.
- Join Us: EF Protocol Reddit AMA - August 29th, 2025 | Ethereum Foundation Blog
The Ethereum Foundation announced that its next Reddit "Ask Us Anything" session will be hosted by the EF Protocol cluster teams, on r/ethereum, on August 29, 2025 at 2 PM UTC. The AMA series, held roughly every six months since January 2019, was previously hosted by the EF Research team, and the name change reflects the organization's restructuring. The foundation says "EF Protocol" covers both foundational research and the development work that brings those ideas to the network. Community members can submit questions in advance, and the topics invited include network upgrades, client development, scaling and the long-term roadmap.
- Southeast Asia welcomes Devcon 7!
Devcon 7 will be held November 12-15 in Bangkok, Thailand, and is being framed as "Devcon Southeast Asia" to reflect a regional rather than city-based focus, according to the EF Devcon Team. The event was scheduled for 2024 after Devcon VI in Bogotá, with the additional time intended to deepen engagement with regional Ethereum communities. The team cites Vietnam, the Philippines, Indonesia and Thailand as leaders in the Global Crypto Adoption Index. It also highlights the Road To Devcon grants round, which has drawn proposals from several Southeast Asian countries.
- Ethereum Protocol Fellowship: Work through the winter
The Ethereum Protocol Fellowship (EPF) has opened applications for its fourth cohort, with the deadline extended to June 18, 2023. The program aims to support development of Ethereum's core protocol by giving aspiring contributors experience working on client implementations, testing, specifications and core protocol research. The fourth cohort runs from July through November 2023 and ends with an in-person event at Devconnect in Istanbul. Selected fellows receive a monthly stipend and access to mentors from the core development community, and the program is also open to permissionless participants, who receive the same benefits and support.
- Ethereum Foundation Allocation Update - Q2 2025
The Ethereum Foundation's Q2 2025 allocation update lists funded projects across community and education, consensus layer, and cryptography and zero knowledge proofs. Community and education entries include conferences and hackathons such as ETH Beijing Hackathon, ETH Belgrade, and Code Africa Hackathon, plus Crecimiento, a Buenos Aires initiative running from May to November 2025. Consensus layer grants include EIP-7917 championed by Lin Oshitani, PeerDAS roadmap support by ProbeLab, and ROP-9.4 FOCIL implementation by Jihoon Song. Cryptography grants include ArkLib by Quang Dao and Poseidon cryptanalysis by Hayk Hovhannisyan, Nerses Asaturyan, and Gohar Hovhannisyan.
- Announcing the Trillion Dollar Security Initiative | Ethereum Foundation Blog
The Ethereum Foundation has announced the Trillion Dollar Security initiative, an ecosystem-wide effort to upgrade Ethereum's security so that billions of individuals and institutions can store large amounts of value onchain. The initiative has three components: mapping security strengths and attack vectors across Ethereum's stack, executing improvements in the focus areas identified, and communicating more clearly about Ethereum's security. Fredrik Svantes (Protocol Security Lead) and Josh Stark (EF management team) are the initial co-chairs, and the foundation is collecting input from users and security firms through a form and at trilliondollarsecurity@ethereum.org.
- Making Ethereum Feel Like One Chain Again | Ethereum Foundation Blog
The Ethereum Foundation's Account Abstraction team proposes the Ethereum Interop Layer (EIL), which would make Ethereum's rollups feel like one chain by letting users sign once for a cross-chain transaction without adding new trust assumptions. The proposal builds on ERC-4337 account abstraction and the Trustless Manifesto, with users initiating and settling cross-L2 actions directly from their wallets rather than through relayers or solvers. Examples include a cross-chain USDC transfer from Arbitrum to Base, an NFT mint on Linea funded from Arbitrum and Scroll, and a swap on an Optimism DEX. The article states that the disclaimer applies: the post is a team proposal and may not reflect consensus views of the Foundation.
- The Ethereum Foundation’s Commitment to Privacy | Ethereum Foundation Blog
The Ethereum Foundation (EF) says privacy must be a core part of Ethereum, and it is expanding its privacy work into a new Privacy cluster coordinated by Igor Barinov. The cluster has 47 researchers, engineers, coordinators and cryptographers, and includes PSE projects such as Private Reads & Writes, Private Proving and Private Identities, along with the Institutional Privacy Task Force (IPTF) and Kohaku, a privacy-preserving wallet and open-source wallet SDK. The EF states that PSE has supported privacy research since 2018, building over 50 open-source R&D projects, including Semaphore, MACI, zkEmail, TLSNotary and Anon Aadhaar.
- Checkpoint #5: July 2025 | Ethereum Foundation Blog
Core developers are focused on releasing the Fusaka upgrade by the end of the year and choosing headline features for the following upgrade, Glamsterdam. Fusaka will bring cheaper L2 transactions and more data availability through PeerDAS, and it has a target of early November for mainnet if testing goes well, with a post-Devconnect date possible if problems arise. EIP-7907 was removed from Fusaka because it lacked benchmarking and risked delaying the timeline. Glamsterdam headliner decisions are expected by mid-August, and the gas limit has been recommended for an increase to 45M.
- The Ethereum Foundation’s Vision
The Ethereum Foundation (EF) restates its vision, role and priorities as a steward of the Ethereum ecosystem, with the stated aim of stepping in where only it can act and stepping back where others can lead. It names two goals: maximizing the number of people who use Ethereum in ways that benefit from its underlying values, and maximizing the resilience of Ethereum's technical and social infrastructure. Examples of EF work include funding client diversity, coordinating core protocol upgrades such as The Merge and Dencun, hosting Devcon, and operating ethereum.org. The post says these priorities are not a rigid plan and are reflected in the strategies of EF's Co-EDs.
- From quarters to cycles: accelerating ethereum.org
The ethereum.org team has adopted Shape Up cycles, with 6-week build periods followed by 2-week cooldowns, and has committed to shipping its first cycle's projects by the end of February with no automatic rollovers. The cycle covers the ethereum.org website, not the Ethereum protocol. Planned work includes an interactive roadmap based on Vitalik's Ethereum roadmap, audio playback for key pages, native Web3 wallet connections, a dashboard hub, a comprehensive content refresh, and a UI migration from Chakra to Shadcn UI components. Ethproofs.org, a platform to track zkVM capabilities, is also listed as launching very soon.
- 2025 EF Internship Program
The Ethereum Foundation is accepting applications for its first formal summer internship program, with applications closing December 9, 2024. The roughly 12-week program aims to develop the next generation of Ethereum developers and researchers, with interns contributing to core projects under mentors on teams such as Protocol Security, Robust Incentives Group, Portal Network, Testing, EELS, Geth and Account Abstraction. Interns can work remotely or from the EF offices in Boulder (USA) or Berlin (Germany), and notifications are expected to be complete by 10 January. The internship differs from the six-month Ethereum Protocol Fellowship, which assumes advanced knowledge and full-time availability.
- Devcon 2024 updates - Secure your tickets, apply to speak, and get involved!
The Devcon team announced that ticket sales are open for Devcon SEA, which runs in Bangkok from November 12-15, and that speaker, volunteer, and other applications are also being accepted. Self-claimable discounts are available to Ethereum contributors whose Ethereum address or GitHub username is eligible, though discounts are limited. General Admission tickets open in waves starting July 16, with no ID required, and speaker applications close July 30, with first decisions expected by the end of August. The post also lists Ethereum SEA Day on November 11, a Bangkok city guide, and programs including the Supporter Program and Impact Teams, both with a July 31 deadline.
- The Sepolia Incident
This blog post discloses an Ethereum network threat, present from the Merge until the Dencun hard fork, in which an attacker could make most nodes (Geth) reject blocks that a minority accepted. The threat stemmed from RPC message size limits carried over to the engine API, which let some clients consider a block valid while others rejected it with HTTP error 413. On February 7, the team found a block could hit the 5MB limit using transactions under 128KB and within 30 million gas, so all clients raised their RPC limits instead. Geth was released with the fix on February 9, and Nethermind, Besu, Erigon and Reth also updated their defaults to safe versions.
- Executive Leadership Update | Ethereum Foundation Blog
The Ethereum Foundation has announced that Tomasz Stańczak is stepping down as Co-Executive Director, and its Board has appointed Bastian Aue as interim Co-Executive Director, effective immediately. The announcement credits Stańczak with strategic guidance that expanded the Foundation's reach to broad groups of people and teams, deeper understanding of ecosystem businesses, and expanded enterprise community development. Bastian Aue, who previously focused on grants, enterprise, and operations as part of the executive team, is described as bringing deep organizational knowledge of the Foundation's structure and values. The Board thanked Stańczak for his service and said the transition is an opportunity to refocus on the work ahead.
- Dencum upgrade scheduled for Mar 13 - lower Ethereum fees coming
The Ethereum Dencun upgrade is scheduled to activate on the Ethereum mainnet at epoch 269568, on March 13, 2024 at 13:55 UTC. The upgrade combines changes to both the consensus and execution layers, most notably EIP-4844, also known as "protodanksharding", which introduces ephemeral data blobs and is expected to help reduce L2 transaction fees. Node operators and stakers must update their clients to the listed releases, or their nodes will be stuck on an incompatible chain after the upgrade. The Dencun upgrade follows last year's Shapella upgrade.
- Glamsterdam Hoodi Testnet Announcement
The Glamsterdam Ethereum network upgrade is scheduled to activate on the Hoodi testnet at epoch 132,352, slot 4,235,264, on October 26, 2026 at 17:42:48 UTC, with Hoodi's gas limit raised to 200M at the same epoch. The upgrade combines the Amsterdam execution layer and Gloas consensus layer changes, headlined by enshrined proposer-builder separation (EIP-7732) and block-level access lists (EIP-7928). Following its activation on Sepolia on October 6, 2026, the upgrade has no mainnet date yet, and node operators must update both their execution and consensus clients before activation.
- The triage is the product: running AI agents against Ethereum's protocol code
The Ethereum Foundation's Protocol Security team argues that the main product of running coordinated AI agents against protocol code is the triage that separates real bugs from plausible-looking ones, not the candidate generation itself. The team reports that its agents found a remotely-triggerable panic in libp2p's gossipsub, fixed and disclosed as CVE-2026-34219. The article's central rule is that a candidate counts as a finding only when a self-contained reproducer runs against the real code for someone who did not write it. It also says the team will not publish its own acceptance numbers, since those would reflect the target more than the method.
- Fusaka Mainnet Announcement
Fusaka is Ethereum's upgrade following Pectra, scheduled to activate on mainnet at slot 13,164,544 (December 3, 2025, 21:49:11 UTC) and described as a major step in the scaling roadmap. Its headline feature is PeerDAS, which lets nodes verify blob data availability through sampling rather than downloading entire blobs. The upgrade also plans two Blob Parameter Only forks on December 9, 2025 and January 7, 2026, raising the per-block blob target and maximum to 10 and 15 in BPO1, then 14 and 21 in BPO2. Users and exchanges generally need take no action, while node operators must update their execution and consensus clients.
- Privacy Cluster Leadership Announcement
The Ethereum Foundation has announced a new leadership structure for its privacy work, with Igor Barinov joining as coordinator of Privacy @ EF and Andy Guzman taking over as coordinator of the PSE team from Sam Richards. Barinov, founder of Blockscout, Gnosis Chain, and zkBob, will guide strategy and alignment across privacy-focused efforts including PSE, while Guzman will lead applied cryptography, research, and development. The Privacy @ EF Cluster organizes PSE's work across research, product, engineering, and operations, and is built around three pillars: Private Reads, Private Writes, and Private Proving. The announcement notes that more than 700 projects are building in the onchain privacy space.
- Trillion Dollar Security - Phase 2 | Ethereum Foundation Blog
The Ethereum Foundation has launched the first wave of actions under its Trillion Dollar Security initiative, focusing mainly on urgent UX security issues for individual and institutional users. It is granting Walletbeat funds to help develop a Minimum Security Standard for wallets, modeled partly on L2BEAT's success. The work also targets blind signing, including promoting the Verifier Alliance (VERA), whose open-source database contains more than eight million contracts, and R&D on transaction decoding and simulation. A separate effort aims to build an open-source database of smart contract vulnerabilities for developer tools.
- The Ethereum Foundation's Next Chapter
Hsiao-Wei and Tomasz, the Ethereum Foundation's new Co-Executive Directors, use a blog post about their first month in the roles to set out the organization's direction for the next 12 months. Their stated priorities are scaling Ethereum mainnet, scaling blobs, and improving UX, including L2 interoperability and the application layer. Tomasz says the Foundation will communicate more openly and focus on speed of execution, accountability, and measurable metrics, while the values of open source, censorship resistance, privacy, and security remain unchanged. Hsiao-Wei says her near-term priority is strengthening the Foundation's operations to support ecosystem growth.
- 10 Years of Ethereum
The Ethereum Foundation is promoting a 10 Years of Ethereum celebration, marking ten years since the genesis block on July 30, 2025, with global community meetups, onchain artifacts and a livestream. The Ecosystem Support Program will fund self-organized, free, open, Ethereum-focused meetups worldwide with up to $500 USD each, and applications close June 15, 2025. The announcement describes Ethereum as having led to breakthroughs in tokenization, fundraising, DeFi and digital ownership, and as transforming into the global settlement layer for the world.
- Ethereum Core Dev Update: Pectra Fork, Testnets, Fusaka Development - March 2025
Ethereum core developers are preparing the Pectra mainnet fork after configuration issues on the Holešky and Sepolia testnets, and they plan to pick a mainnet activation epoch within the next two to three All Core Developer meetings if no unexpected problems arise. Holešky recovered after a majority of the network forked to a non-canonical chain, which led to so many validator exits that the exit queue is a year long, so a new testnet, Hoodi, was launched and will undergo the Pectra fork on March 26th. Development of the following fork, Fusaka, continues in parallel, with PeerDAS and EOF as the two major scheduled features and the Fusaka scope set to freeze on April 10.
- The ETH Rangers Program | Ethereum Foundation Blog
The Ethereum Foundation's Protocol Security Research Team and Ecosystem Funding Initiative have launched the ETH Rangers program, which offers stipends for individuals doing public goods security work on Ethereum. Over six months, selected participants will each receive $25,000 USD. Work can include vulnerability research, educational material, pro-bono incident handling or audits, and developing tools, and current employment in the field does not disqualify applicants. Wave-1 applications are open at ETHRangers.com until December 31, 2024, with recipients selected on January 20, 2025.
- Ethereum Protocol Attackathon is live
The Ethereum Foundation's Protocol Security Research Team and Ecosystem Funding Initiative announced the first Ethereum protocol Attackathon, a time-bound crowdsourced security audit with a $1,500,000 reward pool hosted by Immunefi. It runs from November 25th to January 20th and invites the wider Ethereum community, from auditing firms to individual researchers, to search for vulnerabilities in the protocol's code. Participants begin with an educational phase of live and pre-recorded technical walkthroughs, and only impactful, rule-compliant reports will be rewarded. Bybit, Wormhole, Arbitrum, The Graph, GMX and Base are listed as co-sponsors.
- Sepolia & Holesky Dencun Announcement
Ethereum's Dencun upgrade went live on the Goerli testnet on January 17, 2024, and is scheduled for Sepolia and Holesky, with activation on Sepolia at epoch 132608 (January 30, 22:51 UTC) and on Holesky at epoch 29696 (February 7, 11:35 UTC). The upgrade introduces ephemeral data blobs via EIP-4844, also known as "protodanksharding", which will help reduce L2 transaction fees. Holesky Lodestar users must upgrade to v1.15.0 before activation, and Prysm and Nimbus have recommended v4.2.1 and v24.2.0 respectively. Mainnet deployment will follow if the testnet upgrades go smoothly.
- Dencum will be Goerli's last update before the devs stop working on it
Dencun, Ethereum's upgrade that introduces ephemeral data blobs through EIP-4844, will go live on the Goerli testnet at 6:32 UTC on January 17, 2024, and will be Goerli's last upgrade before core teams stop supporting it. The upgrade will first deploy to Goerli, then to Sepolia and Holesky if no major issues are found, with mainnet activation scheduled afterward. The changes, which combine consensus and execution layer updates, are expected to help reduce L2 transaction fees. Until the upgrade, the article notes that a bug bounty for Dencun-related vulnerabilities pays a 2x multiplier, with critical bugs worth up to $500,000 USD.
- EF's guide to Devconnect
This page is a calendar of side events held around DevConnect, an Ethereum developer gathering in Istanbul in November 2023, listed with their hosts and dates. Events cover topics including Autonomous Worlds, decentralized insurance, Ethereum staking, Starknet, L2 scaling, EVM development, and zero-knowledge proofs. Examples include L2DAYS Istanbul, a two-day technical conference on Ethereum L2 scaling run by L2BEAT and Scroll on November 14 and 15, 2023, and the Programmable Cryptography Conference, hosted by 0xPARC and Privacy & Scaling Explorations on November 16 and 17, 2023. Most listings give a single host, date, and short description.
- The EF’s new structure | Ethereum Foundation Blog
The Ethereum Foundation has restructured into five clusters (protocol, access, user, community and institutional layers) plus operations and management, concluding a months-long reorganization. The change removes 54 colleagues, roughly 20% of the EF, many of whom will look for ways to contribute to Ethereum from outside the organization. Departing staff receive severance equal to the higher of one month's pay per year worked or the amount locally mandated, along with transition support and a small transition grant for expenses such as career coaching. The EF says it will share more about each cluster's structure and work in the coming month.
- Protocol Update 003 — Improve UX
Protocol's "Improve UX" track focuses on interoperability as its highest-leverage opportunity over the next 6 to 12 months, aiming to make cross-chain interactions seamless, secure and permissionless. The near-term strategy centres on intent-based architecture and general message-passing, with work split into Initialisation, Acceleration and Finalisation streams. The Open Intents Framework, a collaborative effort including Ethereum Foundation contributors and teams such as Across, Arbitrum and Hyperlane, is slated to complete its open-source solver and crosschain validation module in Q4 2025. Fast L1 confirmation, led by Roberto Saltini and Mikhail Kalinin (Consensys), targets Q1 2026 availability in all consensus clients, cutting confirmation from 13 to 19 minutes down to 15 to 30 seconds.
- Supporting privacy with new funding mechanisms
The Funding Coordination team and Keyring Network announced a joint initiative routing protocol fees from Keyring's zkVerified permissioned vaults on mainnet to the legal defense funds of Roman Storm and Alexey Pertsev, the Tornado Cash developers currently on trial for publishing open-source code. The fees go to these funds for the first two months, and the article says the model keeps the underlying protocol's economic efficiency intact. Community members can also create vault campaigns that send rewards to the same funds, which the article describes as an impact funding blueprint that could scale across the ecosystem.
- Holešky Testnet Shutdown Announcement | Ethereum Foundation Blog
The Ethereum Foundation announced that the Holešky testnet has reached its planned end-of-life and will be sunset shortly, with most remaining validator nodes shut down two weeks after the Fusaka upgrade finalizes on Holešky. Afterward, client, testing and infrastructure teams will no longer support the network. Staking operators and infrastructure providers are directed to migrate to Hoodi, launched in March 2025, while application and tooling developers should use Sepolia. Holešky's sunset follows extensive inactivity leaks after the Pectra testnet activation in early 2025, which created a large exit queue.
- lean Ethereum | Ethereum Foundation Blog
Vitalik Buterin's... no, the article does not name its author, so I should not attribute it. The post unveils "lean Ethereum," described as a vision and personal mission for Ethereum's next 10 years, with next-generation cryptography presented as central to both defense and offense. It proposes upgrades across all three L1 layers: lean consensus (beacon chain 2.0 with finality in seconds), lean data (post-quantum blobs 2.0), and lean execution (EVM 2.0 built on a SNARK-friendly instruction set, possibly RISC-V). It also cites Ethereum's 100% uptime since genesis and about 130B USD in economic security (35.7M ETH staked at 3.7K USD), and it sets a goal of 1 gigagas/sec on L1 and 1 teragas/sec on L2.
- Shipping an L1 zkEVM #1: Realtime Proving
The Ethereum Foundation proposes shipping an L1 zkEVM in under a year by first letting validators opt into clients that verify several zk proofs from different zkVMs, each proving a different EVM implementation, instead of re-executing blocks. It also proposes a standardized definition of realtime proving for zkVM teams to target, with a latency of 10 seconds or less for the 99th percentile of mainnet blocks, on-prem hardware costing at most 100k USD, power draw of at most 10kW, fully open-source code, at least 128 bits of security, and proof size of at most 300KiB with no trusted setups. The article notes that 100 bits of security would be accepted in the initial months of deployment, and that home proving is intended to strengthen liveness and censorship resistance.
- Partial history expiry announcement
All Ethereum execution clients now support partial history expiry under EIP-4444, which lets node operators remove pre-Merge block data while full rolling history expiry is still in progress. Users can expect to reduce the disk space needed for a node by 300 to 500 GB, allowing a node to fit comfortably on a 2 TB disk. The article states that the default security model is unchanged, since clients have not fully validated the chain from genesis for over 5 years and execution layers will continue to provide all headers for cryptographic verification. History will remain available through institutional providers, opt-in torrents, and the peer-to-peer network, with mirrors listed at eth-clients.github.io.
- Ethereum Foundation's Management and Board Structure
The Ethereum Foundation has announced its new management and board structure, with Hsiao-Wei Wang and Tomasz K. Stańczak appointed as Co-Executive Directors to lead strategic and operational execution alongside other management members. The board, which oversees vision and compliance as a Swiss foundation, includes Vitalik Buterin as Founder, Aya Miyaguchi as President, Patrick Storchenegger as Swiss counsel, and Hsiao-Wei Wang, who also serves as a bridge between the board and management. Tomasz will hold the Co-ED role for an expected two-year term while remaining involved in other companies, including Nethermind and venture affiliations.
- Ethereum Protocol Fellowship Cohort 5 Recap | Ethereum Foundation Blog
The Ethereum Protocol Fellowship has concluded its fifth cohort, which ran for five months and ended with EPF Day at Devcon in Bangkok, and it is preparing a sixth cohort. Of over 300 applicants for the fifth cohort, 20 received initial stipends, and 25 more joined permissionlessly, with 30 active fellows at the end. Fellows contributed to 30 projects with mentors from teams including Grandine, Prysm, Lighthouse, Besu, Nimbus, Nethermind, Geth, Teku, RIG and Reth. The Protocol Study Group, a two-month program on the core protocol, has also been relaunched for 2025, and applications for cohort six are expected in April with a June start.
- Treasury Staking Initiative
The Ethereum Foundation has begun staking about 70,000 ETH from its treasury, with rewards returned to the EF treasury, in line with its Treasury Policy announced last year. It chose the open source tools Dirk and Vouch after assessing several staking software options. Dirk acts as a distributed signer across multiple geographic regions to remove a single point of failure, while Vouch supports multiple beacon and execution client pairings to guard against client diversity risks. The validators use Type 2 (0x02) withdrawal credentials, which the Foundation cites for transferability and a reduced number of signing keys, roughly 35. The first validator has been deposited, with the remaining deposits to follow in the coming weeks.
- Allocation Update - Q1 2025 | Ethereum Foundation Blog
The Ethereum Foundation's Q1 2025 allocation update lists grants across community, consensus layer, and cryptography work. Community and education grants include Account Abstraction Afterhours Season 2, which Mirko Garozzo and Francesco Andreoli are producing as educational videos with account abstraction thought leaders. Consensus layer entries include Sigma Prime's support for the Lighthouse client, covering PeerDAS work. Cryptography entries include Nethermind's Lean blueprint for FRI, Least Authority's Lean blueprints for STIR and WHIR, and Poseidon cryptanalysis projects funded through the Poseidon Grants Round.
- Announcing Ethereum Protocol Fellowship Cohort 6
The Ethereum Protocol Fellowship has opened applications for its sixth cohort (EPF6), which closes April 30, 2025. The program aims to place fellows on R&D teams working on core protocol development, with work covering client implementations, testing and specifications, and core protocol research. For cohort 6, more seasoned software engineers will work on specific projects proposed by client teams, while less-ready participants are encouraged to join the Protocol Study Group. The cohort runs June through November 2025, includes sponsored in-person events at EthCC in Cannes and Devconnect in Argentina, and an introductory town hall is set for April 21 at 4PM UTC.
- Glamsterdam on Hoodi postponed for EIP-8037 review
Core developers decided on ACDE #248 to postpone the Glamsterdam upgrade on the Hoodi testnet, which was previously scheduled for October 26, 2026 at 17:42:48 UTC (epoch 132,352). The delay allows further investigation of how EIP-8037 interacts with mainnet smart contracts, and it removes the Amsterdam execution layer and Gloas consensus layer activations as well as the planned raise of Hoodi's gas limit to 200M. No replacement date has been set, and the article says the new schedule will be announced later. Operators are told to update their clients to releases that explicitly confirm the removal, and the article states that the change does not set a Glamsterdam mainnet date.
- Introducing zkAPI: private usage credits for any API
zkAPI is a system that lets users pay for metered APIs, such as AI inference, without the provider or payment layer being able to link usage to their identity. Users deposit credits into an Ethereum vault contract, then authorize bounded spending with zero-knowledge proofs, and the server mints a short-lived API key that lets prompts go directly from the user's device to the provider. The Open Anonymity Project built it with the Ethereum Foundation, and it runs on Ethereum Mainnet. The article says the protection is limited by network-level exposure such as IP addresses and by prompt content that can re-link sessions.
- Ethereum Foundation Board Update
pcaversaccio (pc) has joined the Ethereum Foundation Board for an initial one-year term on a voluntary basis. pc is a long-time Ethereum contributor, co-founder and lead of SEAL 911, and a member of the EF's Silviculture Society, which provides informal counsel to the EF. pc authored The Ethereum Cypherpunk Manifesto (2024) and Ethereum Privacy: The Road to Self-Sovereignty (2025). The current board members are Aya Miyaguchi (President), Vitalik Buterin (Founder), Patrick Storchenegger (Swiss counsel) and pcaversaccio.
- Checkpoint #6: Oct 2025
Ethereum's Fusaka upgrade is nearly ready, with its first testnet upgrade on Holešky scheduled for 08:48 UTC on October 1, 2025, and mainnet expected about 30 days after the Hoodi fork. The Glamsterdam headliners are enshrined Proposer-Builder Separation (ePBS) and Block-level Access Lists (BAL), while smaller features are still being proposed for about one more week. The article also reports that developers are aiming to raise the gas limit from 45 million to potentially more than 60 million with Fusaka, and it estimates Glamsterdam will land sometime in 2026.
- Fusaka Testnet Announcement
The Ethereum Foundation announces the testnet activation schedule for Fusaka, the upgrade following Pectra, with Holesky activating at slot 5,283,840 on October 1, 2025, followed by Sepolia on October 14, 2025 and Hoodi on October 28, 2025. The headline change is PeerDAS (EIP-7594), which lets nodes verify blob data availability by sampling rather than downloading full blobs, enabling higher blob throughput. Blob Parameter Only forks will then raise the per-block blob target and maximum from 6 and 9 to 10 and 15 in BPO1, and to 14 and 21 in BPO2. Mainnet activation will be chosen after all three testnets upgrade successfully.
