**Ronin**, the blockchain gaming network that has onboarded millions of players over four years, is returning to Ethereum using the **OP Stack**. - The network has established itself as crypto's most proven gaming infrastructure - After years of operating independently, Ronin chose Optimism's technology stack for its Ethereum integration - This move brings millions of existing onchain gamers back to the Ethereum ecosystem The migration represents a significant validation of both Ronin's gaming-focused approach and the OP Stack's scalability solutions for high-throughput applications.

**Critical deadline approaching for OP Stack operators** op-geth will be deprecated on May 31st, requiring all OP Stack chain operators to transition to op-reth validator nodes. **Why start now:** - Node synchronization takes significant time - snapshots should be prepared in advance - Running validators carries no risk, eliminating the need to wait for devnet testing - Early deployment allows time to identify and resolve network-specific issues Operators should begin the migration process immediately to ensure a smooth transition before the deadline. For complete migration instructions, see the [op-geth deprecation docs](https://docs.optimism.io/notices/op-geth-deprecation)

Re7 Capital has introduced **mRe7ETH**, an ETH-denominated investment product on OP Mainnet targeting institutional allocators. **Key Details:** - Product accessible through Midas platform - Expands DeFi product offerings on OP Mainnet - Reflects growing DeFi activity in the ecosystem *Important Disclosures:* Re7 operates independently of Optimism Foundation and OP Labs. The Foundation has committed ETH to Re7's ETH Yield strategy, creating a financial interest in mRe7ETH. Participation in digital asset protocols carries risk—conduct thorough due diligence before use.

**Privacy Boost** by Sunnyside is now live on OP Mainnet, marking the first privacy solution from an Optimism core developer. **Key Features:** - Drop-in SDK for confidential computing across any OP Stack chain - Hybrid ZK + TEE (Trusted Execution Environment) architecture - Sub-500ms proof generation with high throughput - Compliance-compatible design **Why It Matters:** Institutions have been asking how to move onchain without exposing sensitive customer data. Sunnyside built this solution specifically to address that need on the OP Stack. The launch comes as the Superchain processes 59% of all L2 transactions, providing a large anonymity set crucial for privacy applications.

The OP Stack is enabling a new era of blockchain customization, according to insights from @karl_dot_tech. **Key Points:** - Customization allows blockchains to be tailored for specific use cases and requirements - The OP Stack provides the infrastructure to make this customization technically feasible - This represents the next significant wave of innovation in crypto development The ability to customize blockchains opens new possibilities for developers to create specialized solutions rather than one-size-fits-all networks.

The **Scaling Summit** brought together founders and builders to address critical industry challenges: - **User retention** in an attention-scarce market - **Product differentiation** in a crowded builder landscape - **Compliance frameworks** that balance regulation with innovation momentum - **RWA and stablecoin adoption** beyond builder narratives toward mainstream use The event focused on practical solutions rather than theoretical discussions, with participants examining how to move from concept to global implementation.

The **Superchain ecosystem** now handles **14.1% of all cryptocurrency transactions**, representing nearly **2x growth** in just five months. **Key metrics:** - $17.8B secured across 30+ chains - 24M+ daily transactions - $6.2B in stablecoins onchain Major chains include Base, Celo, OP Mainnet, Unichain, World Chain, and others building on Ethereum's scaling infrastructure. This growth demonstrates the **increasing adoption** of Layer 2 solutions as users seek faster, cheaper transactions while maintaining Ethereum's security.

**Fusaka is now live on Ethereum mainnet**, delivering the infrastructure needed for Layer 2 scaling. The upgrade introduces **PeerDAS**, which allows validators to sample small data chunks instead of downloading full blobs. This reduces storage requirements from 40-100 GB to just sampled shards. **Key improvements:** - More blob capacity for rollups through Blob Parameter-Only forks - Gas limit increase from 45M to 60M - Lower data availability costs for L2s - Reduced fees for end users The upgrade emerged from **cross-ecosystem collaboration** between Ethereum core developers, client teams, Base, Soneium, OP Labs, and Sunnyside. Teams worked together to solve L2 scaling bottlenecks that were causing rising fees. **For builders:** OP Stack chains now have more throughput headroom, lower L1 data costs, and a predictable scaling roadmap. The implementation included extensive testing through devnets that pushed different client combinations under real rollup workloads.

**Scaling isn't just about bigger numbers** - it's about delivering real value to users, according to insights from @karl_dot_tech at the New Horizon event. Key challenges identified: - Compute bottlenecks - Parallelism implementation - Cross-chain liquidity issues **Real progress requires solving these together**, not chasing TPS metrics alone. *"Through interoperability, we grow the pie. You can build something a competitor builds on, and both of you win."* The focus shifts from raw performance claims to **practical solutions** that enhance user experience and enable true blockchain collaboration.

Optimism Collective announces its H2 strategic goal: achieving $100M monthly in cross-chain asset transfers across interoperable Stage 1 chains. The Citizens House introduces three stakeholder groups: - Top 15 chains by revenue - Top 100 apps by gas fees - End-users with verified activity Key registration requirements: - End-users must prove human status via WorldCoin - Limited spots available - Sybil protection through HumanPassport screening This follows Optimism's recent $2M bug bounty extension for Superchain protocol upgrades, which has already paid out $2.6M since 2022.
