**Payy** has launched as a privacy-focused stablecoin chain built on Ethereum. The platform enables programmable payments while keeping transactions private by default. **Key features:** - Transactions aren't publicly exposed - Maintains privacy without compromising Ethereum compatibility - Designed specifically for stablecoin payments This follows a similar privacy trend in the Ethereum ecosystem, with projects like [Fluidkey](https://fluidkey.com) recently launching to help users receive and manage funds without linking them to their public identity. Payy represents a growing focus on bringing privacy features to Ethereum's payment infrastructure while maintaining the network's programmability and composability.

Ethereum's weekly All Core Developer calls generate significant discussion that can be challenging to follow. A new **"Checkpoint" series** addresses this by providing: - High-level updates every 4-6 weeks - Digestible summaries of core development progress - Regular tracking of important protocol changes The series aims to make Ethereum's technical development more accessible to the broader community by condensing complex developer discussions into manageable updates.

**Key Ethereum Developments:** - Pectra upgrade live with smart account features and 2x L2 capacity - Stripe launches stablecoin accounts in 101 countries - Uniswap reaches $3T all-time swap volume - Multiple L2s reach Stage 1: Base, Kinto, Scroll, and Starknet **Technical Achievements:** - ZKSync achieves full EVM equivalence - SuccinctLabs/RiscZero reduces block proving to 12s - Aztec launches public testnet for private L2 **Adoption Highlights:** - Coinbase integrates Farcaster social - AAVE partners with ANT for RWA marketplace - WorldID verifies 12.5M humans on L2 - MorphoLabs hits $1B TVL on Base

Microsoft Fabric users can now access Ethereum blockchain data through Space and Time's integration. This development marks a significant step in enterprise blockchain adoption. - The integration enables direct querying of Ethereum on-chain data - Space and Time, operating on ZKsync Chain, provides ZK-verified data - Enterprise users can now access trustless, queryable blockchain data for business analytics This collaboration bridges the gap between traditional enterprise systems and blockchain technology, making Web3 data more accessible to mainstream businesses.

A new 'Checkpoint' series has been introduced to provide condensed updates from Ethereum's weekly All Core Developer calls. - Series will cover 4-5 calls per update - Focus on high-level development progress - Aims to make technical discussions more accessible The initiative comes as Ethereum continues to evolve, with recent discussions including the Dencun upgrade coordination among core developers. *Follow the Checkpoint series to stay informed about Ethereum's technical development without getting overwhelmed by weekly details.*

The Ethereum Foundation emphasizes its dedication to treating information as a public good, highlighting two key initiatives: - **Research Grant Program**: Launched in 2022 to support academic research and knowledge sharing - **Next Billion Fellowship**: Focuses on documenting community impact stories and technological accessibility These programs align with the Foundation's core mission of keeping technology open and accessible while fostering community-driven development. *Learn more about ongoing research opportunities and fellowship applications through the Ethereum Foundation portal.*
