Odaily News XION, a wallet-free Layer 1 blockchain dedicated to promoting the mainstreaming of Web3, today officially released its flagship mobile development toolkit, Dave, which will open Web3 channels to more than 18 million mobile developers and 5.8 billion mobile users worldwide. Dave supports native iOS and Android. Developers can achieve on-chain identity authentication and interaction through a process similar to Google OAuth without docking wallets or jumping links, truly making blockchain "invisibly" integrated into mainstream apps. This innovation has greatly lowered the threshold for using Web3 applications and truly realized "making Web3 as easy to use as Web2." Burnt Banksy, founder of XION, said, "Mobile has long been a blind spot in the crypto industry, and this is precisely the main entry point for most Internet users. With Dave, developers will be able to create Web3 applications that are as intuitive as Web2, which is an important step in our vision of popularizing Web3." At the same time, XION will launch a developer hackathon competition centered on mobile terminals to encourage developers to use Dave to build truly feasible and user-friendly mobile applications. The competition will last for 6 to 8 weeks and will be open to all Web2 and Web3 developers, ushering in a true wave of popularization of Web3.

Odaily News Aptos Labs CEO Avery Ching will testify at a hearing in the House of Representatives on June 4, US time, sharing his unique perspective on blockchain infrastructure construction. The theme of the hearing is "American Innovation and the Future of Digital Assets: From Blueprint to Practical Framework", which aims to promote the formulation of a clear and practical legislative framework for digital asset market structure. As one of the very few founders and CEOs of Layer 1 Blockchain Technology invited to speak in Congress, Avery will explain the core role of tokens in open networks, practical use cases on Aptos, and the importance of clear regulation to American technological innovation from the perspective of engineers and builders. This hearing is led by the Agriculture Committee, which is responsible for supervising the CFTC (Commodity Futures Trading Commission), and has a substantial impact on digital asset market structure legislation. Avery's testimony will be included in the official record and may provide key references for future policy making.

Odaily News On May 20, Tabi founder Xavier pointed out that in the past, the success of public chains often relied on innovative applications within the ecosystem, such as ETH's ICO and DeFi Summer. However, as the industry matures, this traditional path has gradually become ineffective. He mentioned that HyperliquidX, as a model of "fat application and thin protocol", shows a new direction for the development of public chains in the future. Compared with the numerous DApps, future public chains should focus more on the application chain model to improve efficiency and practicality. Application chains may become the key to the success of the next generation of public chains. In addition, Xavier also affirmed Cosmos' contribution to the application chain field. From account abstraction to inter-chain communication, these concepts provide an important theoretical basis for the future development of Layer 1.

Odaily News According to the official announcement, BitMart will launch Obol (OBOL) at 19:00 (ET) on May 7, and the OBOL/USDT trading pair will be launched. Obol is committed to the distributed, decentralized and democratized digital infrastructure of the future - starting with Ethereum and expanding to the entire Web3 platform. As the foundation of the Layer 1 blockchain and decentralized infrastructure network, Obol Collective has the world's largest decentralized operator ecosystem.

Odaily News Pharos Network, the RWA public chain, announced today that its test network will be officially launched on May 7. The test network released this time aims to demonstrate Pharos' innovative Layer 1 solution, which has high throughput and can increase the transaction speed on the chain; at the same time, EVM compatibility allows developers to migrate and deploy Ethereum applications, thereby accelerating the development of the RWA ecosystem on the chain.

Odaily News Vitalik and StarkWare-backed Kakarot announced the development of an independent Ethereum zero-knowledge proof (ZK) stack, and plans to achieve real-time Layer 1 block proof by the end of 2025. Kakarot is built on the Cairo language and uses the STARK system to avoid dependence on the existing mainstream ZK technology stack. It aims to enhance the diversity and system resilience of Ethereum ZK verification and help achieve Ethereum's goal of full ZK in 2028. (The Block)

Odaily News Scroll co-founder Ye Zhang tweeted that Scroll has achieved a key upgrade through the Euclid update, becoming the first zk-Rollup to reach Stage 1 status, ensuring that users have enough time to exit before the system changes, supporting Layer 1 forced transaction submission, and the network can be automatically opened when the sequencer or prover goes down, ensuring the system is active.

Odaily News On April 29, Bitlayer, a project based on the BitVM technology of the Bitcoin ecosystem, announced that BitVM Bridge has been connected to the Monad testnet, allowing users to experience the cross-ecological BTC bridging function in a trust-minimized manner. Monad is an emerging high-performance Layer 1. The total number of active users of the network has exceeded 9.8 million, and the number of independent wallets has exceeded 69 million. After the completion of this integration, Monad's tens of millions of ecological users will have the opportunity to directly experience the first BitVM-based landing application BitVM Bridge, bridging the vBTC on the BitVM Bridge testnet (BitVMNet) to the Monad Testnet, minting the corresponding YBTC, and exploring the financialization of YBTC in the Monad ecosystem. At the same time, BitVM Bridge now supports the function of bridging YBTC back to BitVMNet, and users are welcome to log in to experience it.

Odaily News Ethereum core developers are considering quadrupling the Gas limit of Layer 1 as a key feature of Fusaka, the next hard fork after Pectra. On April 23, developer Sophia Gold proposed EIP 9678, proposing to increase the Gas limit to 150 million during the Fusaka hard fork. On April 24, core developer Tim Beiko said in the meeting summary that the ACDE meeting had discussed raising the Gas limit as a "key feature" of Fusaka. Developers have drafted an EIP and plan to merge it early next week and formally propose it at the next ACDE meeting. As work progresses, changes may be required within the protocol to support a higher Gas limit, and even if the hard fork range is set, more EIPs will need to be added for Fusaka. Pectra plans to launch its mainnet in May, and Fusaka may be launched at the end of 2025. Developers said that increasing the Gas limit is intended to expand Layer 1 execution capabilities, and no new features are needed, but guidance from execution layer developers is needed to test and fix client vulnerabilities, so it is reasonable to include it in the hard fork EIP. On February 4, validators supported raising the network's Gas limit, increasing the maximum amount of Gas used for transactions in a single Ethereum block. Ycharts data shows that the current value is slightly less than 36 million. (Cointelegraph)

Odaily News R2, the RWA stablecoin yield protocol, announced that it has completed its deployment on the Plume testnet, marking a key step in its multi-chain strategy. Plume is a high-performance Layer 1 public chain focusing on the RWA track (RWAFi), dedicated to providing infrastructure support for real assets on the chain. Since the testnet was launched 5 days ago, the R2 protocol has attracted more than 55,000 users worldwide to participate in the interaction. Users can receive test tokens through Discord, experience functions such as minting R2USD, staking R2USD, BTC, ETH, and receive points rewards. Officials said that R2 will access more test networks in the near future, continue to expand the multi-chain ecosystem, and enrich the access path of underlying assets. R2 aims to create the next generation of stablecoin protocols with real returns, redeemability and transparency. The underlying assets cover diversified sources of income such as on-chain US bonds and compliant MMF strategies. The mainnet is expected to be officially launched in the second quarter of 2025.
