📰 Key TakeawaysFusaka mainnet upgrade scheduled for early NovemberDevnet-3 launching July 23, with EIP 7907 removedePBS and BALs likely to headline GlamsterdamDevelopers aim to finalize Glamsterdam priorities in 2–4 weeks📺 All Core Developer Calls AllCoreDevs - Execution (ACDE) Call #216 Fusaka Upgrade: Developers agreed on a proposed timeline for Fusaka’s mainnet launch in early November, with public testnet upgrades starting late September. To speed up testing, they removed EIP 7907, which proposed changes to smart contract code size limits. The next devnet (Devnet-3) is expected to launch July 23, including updates to EIP 7825 and pending decisions on the engine_getblob API. Glamsterdam Planning: Client teams showed strong early support for making enshrined proposer-builder separation (ePBS) and block-level access lists (BALs) the main features of the next upgrade, Glamsterdam. A final decision is expected in 2–4 weeks, pending more community input. Why this matters: These upgrades aim to improve scalability, censorship resistance, and the developer experience on Ethereum—impacting how builders deploy contracts and how users interact with the chain under high load. Action Items and Timelines:Fusaka UpgradeJuly 22 – Decide on engine_getblob APIJuly 23 – Launch Devnet-3Late August – Release clients for public testnetsSept 22 – Oct 3 – First testnet upgradeOct 6 – 10 – Second testnet upgradeNov 5 – 12 – Mainnet launch 🚀Glamsterdam PlanningNow – Start building ePBS + BALsNext 2–4 weeks – Get feedback from Flashbots, L2s, and othersAugust 1 – Confirm upgrade features on next ACDE call All Core Devs - Testing (ACDT) #44Testing updates for protocol changes were the focus, ensuring smooth deployment of upcoming Ethereum updates. Why this matters: Guarantees reliable and seamless user experiences during network upgrades. Action Items: Extensive testing and bug fixes for upcoming features. Timeline: Ongoing through Q4 2025. 🧪 Protocol Research ➗ The Glamsterdam EquationEthereum Foundation researchers have introduced the "Glamsterdam Equation," a new method designed to improve Ethereum’s security by optimizing validator incentives. Simply put, this equation helps balance rewards and penalties for validators, ensuring network health and stability while deterring malicious activity. Why this matters: Improves security for users and gives developers a clearer validator incentive structure. Action Items: Formalize incentive structures and conduct simulations. Timeline: Initial testing by Q4 2025.⌛ State Expiry RoadmapEthereum developers discussed updates to the state expiry roadmap, specifically addressing how to efficiently remove outdated or unused data (state). This helps Ethereum remain scalable by reducing the storage burden on validators and improving performance. Why this matters: Users will enjoy faster transactions and lower network fees. Action Items: Finalize implementation proposals and testnet deployments. Timeline: Targeting rollout by mid-2026.🌐 Stateless Ethereum and SIC CallsIn recent SIC (Stateless Ethereum Implementation Call), developers focused on refining approaches to "stateless Ethereum," a technique designed to minimize Ethereum nodes' storage requirements. Stateless Ethereum allows nodes to operate with minimal data, significantly enhancing decentralization. Why this matters: Users will experience greater network resilience and decentralization. Action Items: Continue developing prototype nodes and optimize proof generation methods. Timeline: Prototype evaluations ongoing through 2025.🛡 Privacy-Preserving Sybil ResistanceNew research proposes using Multi-Party Computation (MPC), TLS protocols, and Semaphore proofs to enhance privacy-preserving mechanisms against Sybil attacks, where fake identities flood networks. Why this matters: Users' privacy and network integrity will be significantly improved. Action Items: Develop protocol demonstrations. Timeline: Protocol testing by early 2026.🔒 FLUXE: Universal Privacy ProtocolFLUXE introduces a universal privacy protocol designed for cross-chain stablecoin payments, combining privacy and compliance. Why this matters: Users can securely and privately transact across multiple blockchains. Action Items: Cross-chain protocol integration tests. Timeline: Integration testing throughout 2026.🧠 Post-Quantum Signature Interop (PQ-Interop)Researchers discussed interoperability of post-quantum cryptographic signatures, focusing on future-proofing Ethereum against quantum computing threats. Why this matters: Ensures long-term security for users against future quantum attacks. Action Items: Develop and test interoperability standards. Timeline: Initial standards proposal by late 2025.🏁 Thanks for Reading Ethereum Daily!
