All Core Devs Call on Pectra, History Expiry & Fusaka
Ethereum Foundation held an All Core Developers call to discuss the upcoming Pectra mainnet upgrade, the rollout of history expiry, and the finalized scope for the Fusaka hard fork.
During the call, core developers confirmed that Pectra is scheduled to ship on mainnet on May 7, 2025, with client releases already live on the new Hoodi testnet, marking it as the largest protocol fork in Ethereum’s history by EIP count.
They also outlined the history expiry feature, which will enable optional pruning of pre-merge state to reduce hardware requirements; Sepolia support is expected by May 1, followed by a mainnet rollout immediately after Pectra.
Fusaka’s scope has been locked in, centering on the PeerDAS EIP for zk-sampling blobs and formalizing the All Core Devs process to split testing and scoping calls, streamlining upgrade workflows and accelerating future delivery.
The discussion briefly noted that EOF (EVM Object Format) was deferred from Fusaka’s agenda due to complexity and maintenance considerations, postponing its evaluation to later upgrades.
Scroll Euclid Upgrade with 90% Lower Fees and 4x Throughput
Scroll has announced the Euclid upgrade, its most substantial protocol transformation since mainnet launch, promising 90% lower data-availability costs and a fourfold increase in transaction throughput.
In phase‐1 testing, Scroll migrated to an OpenVM prover architecture to reduce proving latency and audit complexity, enabling support for arbitrarily complex transaction types without the previous circuit-capacity constraints.
The upgrade also transitions state commitments from Halo2 zktrie proofs to a Merkle-Patricia Trie (MPT) model, enhancing sequencer performance and improving compatibility with dApps that rely on Ethereum-native proof structures.
Euclid implements an optimized rollup process by moving blob verification into the zero-knowledge circuits, amortizing message-queue costs, and allowing multiple blob commitments per transaction to lower gas overhead further.
Support for EIP-7702 and RIP-7212 introduces smart-account features and a dynamic fee market for blob storage, unlocking next-generation UX improvements and passkey-based authorizations for layer-2 applications.
Scroll has already activated Euclid on Sepolia testnet (March 13, 2025) and plans a phased mainnet rollout with rigorous devnet and backtest validations to ensure stability across five test environments. Node operators and indexers are advised to prepare for MPT migration and updated batch-commit flows.
By combining lower costs, higher throughput, and enhanced security mechanisms like permissionless batch submission, Euclid positions Scroll as a leading zk-rollup ready for Stage-1 decentralization standards.
5 Account Abstraction Use Cases by Etherspot with developer tips
Etherspot has highlighted five real-world Account Abstraction use cases, urging developers to adopt features that streamline dApp user experiences:
- Gasless transactions, allowing users to interact without needing native gas tokens
- Session keys, enabling multiple actions in a single session without repeated signing prompts
- Social recovery mechanisms for lost wallet access
- Automated streams and recurring payments for DeFi activities
- Web2-style onboarding flows that mirror familiar authentication methods
Developers can integrate these patterns using our Modular SDK and Arka Paymaster, with step-by-step guidance and code samples to simplify implementation and reduce friction.
By demonstrating these practical examples, the Etherspot team aims to accelerate the adoption of account abstraction standards and equip Web3 builders with tools to create smoother, smarter experiences.
Ethereum to Standardize Cross-Chain Addresses with ERC-7930 & ERC-7828
Ethereum core contributors have announced that two interoperable address standards, ERC-7930 and ERC-7828, will be finalized on May 9, 2025, to streamline cross-chain transactions and reduce user errors.
The ERC-7930 specification will introduce a machine-readable format that unambiguously identifies which network an address belongs to, ensuring that wallets, dApps, and smart contracts interpret addresses consistently.
Wonderland, a multi-protocol development team, explained that “users and apps need ways to unambiguously refer to an address on a specific chain,” highlighting that the lack of a standard format has led to costly mistakes when assets are sent to the wrong network.
Implementation is expected across major wallets and cross-chain protocols shortly after final ratification, with developers focusing on backward compatibility and minimal integration overhead.
By unifying address handling, these standards aim to enhance the overall user experience, boost confidence in cross-chain interactions, and pave the way for more seamless interoperability across Ethereum Layer 1 and its growing ecosystem of sidechains and rollups.
Base Achieves Stage 1 Decentralization
Base has achieved Stage 1 Decentralization by launching permissionless fault proofs and establishing a decentralized Security Council to oversee contract upgrades.
This milestone delivers stronger security guarantees and reduces trust assumptions by allowing any participant to propose and challenge state claims onchain without relying on a central operator. Fault proofs enable permissionless proposals and challenges, ensuring users can withdraw funds from Base to Ethereum without intermediary control.
The newly formed Security Council, composed of ten independent entities from diverse jurisdictions, must approve contract upgrades alongside Base and Optimism at a 75% threshold, preventing any single party from unilaterally altering network rules. Upgrades cannot proceed without broad stakeholder consensus.
Vitalik Buterin’s three-stage decentralization framework underpins this progression, defining Stage 1 as “limited training wheels” where fault proofs and decentralized overrides enhance resilience and reduce points of failure. Base’s implementation aligns with this roadmap, moving beyond operator-driven validity checks toward a more robust, permissionless model.
Looking ahead, Base plans to integrate multiple proof systems, including ZK-based fault proofs, and to advance toward Stage 2 full decentralization, where no group can override protocol outputs except in defined bug scenarios.
