Fabric, a collaborative initiative focused on standardizing rollup infrastructure, introduced Signal-Boost, a proposed mechanism that enables Ethereum rollups to access L1 data in real time. Designed to be sequencer-agnostic, Signal-Boost works with both existing rollups that use dedicated sequencers and based rollups, without requiring any changes to their underlying stacks.  The sequencer collects read-only L1 queries, executes them, hashes the results into a Merkle tree, and publishes the root to a SignalService contract on L1. The root is then included in the L2 block, allowing L2 contracts to verify L1 data using Merkle proofs. Signal-Boost enables real-time, same-slot access to arbitrary L1 data from L2 contracts, supporting use cases like instant deposits, live oracle reads, and atomic cross-chain transactions.

Coinbase disclosed a data breach involving its overseas customer support operations, where a small group of employees were bribed to leak customer data. Exposed information included full names, addresses, phone numbers, emails, partial Social Security and bank account numbers, government ID images, and account data. The attackers demanded a $20 million ransom, which Coinbase refused to pay. Instead, Coinbase launched a $20 million bounty for information leading to the attackers’ conviction. Coinbase notified affected users—fewer than 1% of its 100+ million customers—and committed to reimbursing those who have lost funds.

Obol Network introduced the Obol Stack, a modular, plug-and-play framework for building, distributing, and running decentralized applications and infrastructure. Leveraging Kubernetes and Helm, the Obol Stack brings scalable, composable, and accessible enterprise-grade software delivery to the Ethereum ecosystem. Networks and developers can package and distribute systems, while node operators can discover and run them to earn rewards. Obol Network is a Distributed Validator Technology (DVT) protocol, securing over $1 billion in staked ETH across validators on its network. It is also the first protocol to go live on Tally Staking with stOBOL tokens.

Privacy Pools, an onchain privacy protocol leveraging ZKPs for private token transfers, has temporarily paused new deposits following the discovery of a bug affecting two user transactions. The issue occurred when two deposits were made back-to-back, causing the reuse of the same preCommitmentHash. The bug led to duplicate nullifiers, which are necessary for withdrawal, rendering the affected deposits permanently stuck. Only two deposits were impacted, totaling 0.2 ETH. The Privacy Pools team has reimbursed the affected users. All other funds in the contract are not affected, and users can still withdraw or exit. A smart contract fix is being implemented to prevent the issue from recurring.
