**OP Enterprise** introduces production-grade managed blockchain infrastructure, allowing companies to deploy custom OP Stack Layer 2 chains without operational complexity. **Key Features:** - Partners handle deployment and operations of custom L2s - Businesses retain ownership of their blockchain and revenue - Teams can focus on outcomes rather than infrastructure management The approach mirrors **Circle's success** with Visa stablecoin settlements, where technical complexity was abstracted away. OP Enterprise positions itself as infrastructure-as-a-service, ensuring enterprises receive ongoing support while exploring blockchain applications. This model addresses a common barrier: companies typically adopt services that deliver results, not infrastructure they must operate themselves.

The **Optimism Scaling Summit** has revealed its speaker roster, featuring teams advancing blockchain scaling solutions across multiple domains. **Key Focus Areas:** - Throughput optimization - Payment systems - Privacy solutions - Onchain entertainment **Participating Organizations:** Kraken, Dromos Labs, Celo, XLayer, Alchemy, Startale Group, Nethermind, Succinct Labs, LayerZero, Morpho, Gauntlet, Base, Spark, Flashbots, and OP Labs. The summit will take place in Denver with worldwide streaming available for remote participants.

**OP Labs is assuming complete ownership of OP-Reth specific crates**, marking a significant shift in the governance of this critical infrastructure. **Key Details:** - OP-Reth was originally co-developed by OP Labs and Paradigm engineers - Built using the Reth SDK to enhance OP Stack scalability - Serves as the primary high-performance execution client across the Superchain **Why This Matters:** As OP-Reth becomes increasingly critical infrastructure, direct stewardship by OP Labs aims to ensure: - More reliable release cycles - Continued development momentum - Streamlined maintenance and updates **Commitment to Ethereum:** OP Labs emphasized their dedication to maintaining a cohesive Ethereum ecosystem and will continue contributing improvements upstream.

As AI agents proliferate across digital systems, **proof of human** verification is emerging as a critical infrastructure component. The technology addresses three key challenges: - **Trust**: Distinguishing human actors from automated agents in online interactions - **Control**: Maintaining human oversight and decision-making authority - **Fairness**: Ensuring equitable access and preventing bot manipulation This verification layer becomes increasingly vital as autonomous agents handle more complex tasks and transactions. The framework helps preserve human agency while enabling AI assistance to scale effectively.

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.

The Superchain ecosystem continues to expand with the OP Stack emerging as the dominant L2 solution. Key metrics include: - 50+ chains and $17B+ in TVL - 6 of top 10 L2s running OP Stack - Powers 70% of all L2 transactions Recent developments: - Four networks (OP Mainnet, Base, Unichain, Ink) reached Stage 1 decentralization - Flashblocks upgrade reducing transaction times to ~200ms - Native interop features coming this summer - Growing number of teams joining Superchain Incubator The platform emphasizes security, speed, and seamless cross-chain interactions while maintaining Ethereum compatibility.

Two major audit contests have been announced for blockchain security: - **Superchain Security Contest** Open invitation for whitehats and developers to audit code for secure interoperability [Contest Details](https://cantina.xyz/competitions/44b385bf-e51a-4e6c-b3a8-adbbe24d16e1) - **STRK Staking Contract Audit** CodeHawks contest starting April 4th Prize pool: $80k USDC KYC required [Registration Link](https://codehawks.cyfrin.io/c/2025-04-starknet-part-2) *Both contests offer opportunities for security researchers to contribute to blockchain infrastructure security.*
