ChainCatcher news, co-hosted by ChainCatcher and ZAN (the Web3 brand under Ant Group) and Artela, held an offline communication event titled "Focusing on Web3 Infrastructure, Unlocking New Scenarios for DApp Applications" today in Nanshan District, Shenzhen. During the event, Artela's CTO CP shared a presentation titled "EVM++, Unlocking Parallel EVM and On-Chain Scalability."In the presentation, Artela's CTO CP mentioned that EVM++ is Artela's upgrade to the next-generation EVM execution layer technology. It unlocks the extensibility and scalability of EVM blockchains through EVM+WASM, while also supporting parallel execution of EVM.EVM++ aims to expand the boundaries of EVM, allowing existing EVM assets, protocols, and infrastructure to seamlessly connect with new ones, facilitating mass adoption applications and accelerating the integration of crypto with mainstream at the application level.Additionally, Artela has made innovations at the infrastructure layer compatible with EVM, launching Aspect programming, which allows developers to build EVM+ applications using the EVM+Aspect paradigm, and has developed many innovative extension use cases covering areas such as AIpto, full-chain gaming, DeFi security, and middleware.

ChainCatcher news, CertiK tweeted that a significant vulnerability has been discovered in the smart contract platform CosmWasm within the Cosmos ecosystem, which could lead to a network-wide outage. They have promptly reported it and collaborated with the CosmWasm team to release an effective patch, and have notified potentially affected application chains to ensure preventive measures are taken to address the issue without impacting users.

ChainCatcher news, Sei Labs co-founder Jayendra (Jay) Jog posted on social media that Sei v2 will support both EVM and Cosmwasm.It is reported that by using stateful precompiles and chain-level message scheduling, EVM and Cosmwasm contracts will also be able to call each other.

ChainCatcher news, according to The Block, the Cosmos-based blockchain Neutron has acquired a 25% stake in CosmWasm developer Confio. This investment and strategic partnership aim to increase the adoption of CosmWasm and align the development strategies of Neutron and Confio. Neutron did not disclose the amount of the investment.

ChainCatcher news, the NEAR Foundation announced a collaboration with Polygon Labs to build zkWASM based on Polygon CDK, aimed at developing zero-knowledge provers for WASM blockchains. The zkWASM prover will be an upgrade for NEAR validators, bringing the NEAR protocol closer to Ethereum and allowing WASM chains to leverage Ethereum liquidity, paving the way for greater trustless interoperability between the NEAR and Ethereum ecosystems. The zkWASM prover is currently under active development and is expected to be launched next year. Additionally, the NEAR Foundation has become a core contributor to Polygon CDK.

ChainCatcher news, the Ava Labs team has launched the WASM-based smart contract framework HyperSDK Programs. In the coming weeks, the Ava Labs team will release HyperVM, which allows for permissionless deployment of HyperSDK programs.It is reported that WASM is a binary instruction format tailored for stack-based virtual machines, designed as a portable target that allows high-level languages such as C, C++, and Rust to be compiled and executed on different platforms with near-native performance. To avoid memory allocation and serialization bottlenecks in WASM, HyperSDK programs never inject complex objects into the WASM execution at runtime, but only reference them in the host memory space.

ChainCatcher news, Binance Labs announced an investment in zkWASM infrastructure provider Delphinus Lab, which provides developers with the first fully implemented open-source zkWASM virtual machine. This funding will be used for the ongoing development of Delphinus Lab's zkWASM-based application upgrade platform, zkWASM Hub, which offers automatic proof and batch processing services for Web3 application development.

ChainCatcher News: Ethereum zkWASM Execution Layer Fluent announces the upcoming launch of its testnet, and is currently accepting applications for its early builders program.Fluent integrates three key innovations: alleviating application performance and cost constraints through ZK Rollup; supporting programming languages such as Rust, TypeScript, and Go via a WebAssembly virtual machine; and EVM tool compatibility to enable features like Solidity, MetaMask support, and account abstraction.

ChainCatcher message, the Bitcoin security sharing protocol Babylon has completed the v0.7.1 testnet upgrade, supporting all smart contract functionalities based on the CosmoWasm and Wasmd frameworks, allowing developers to extract security from Bitcoin to protect their applications and blockchains by deploying Babylon smart contracts.According to RootData data, Babylon completed an $8 million seed round financing on January 1, 2022, and on March 9, 2023, Babylon launched its testnet. The Babylon testnet has integrated with 28 Cosmos SDK chains, including Osmosis, Akash, Sei Network, Injective, Evmos, and Stride. This upgrade expands Babylon's capabilities beyond the Cosmos ecosystem, enabling it to cater to a broader range of applications.

ChainCatcher message, the "Zhen" series event co-hosted by ChainCatcher and RootData was held today in South Korea, with the theme "The New Opportunity of Web3 in Seoul." Sarah THIAM, the head of developer experience for FVM (Filecoin Virtual Machine), mentioned the FVM development roadmap and basic tutorials in her keynote speech.Sarah mentioned that the Filecoin Virtual Machine (FVM) launched this year has fully achieved compatibility with EVM, and the upcoming development plans include storage transaction aggregation standards, storage transaction replication, repair, and renewal standards, local WASM execution, and providing more partner integration virtual machine tools, among others. Additionally, she elaborated on how FVM can be specifically applied using Biscuit DataDAO as a case study.Filecoin is a distributed cloud storage network that currently has over 20 EB of capacity. Since 2014, Filecoin and IPFS have provided useful and popular storage and retrieval functionalities. This year, the Filecoin Virtual Machine (FVM) was launched, now offering programmable storage, unlocking the potential for developing network-scale applications. In the future, FVM will introduce computation to data after Filecoin builds the world's largest distributed storage network to support network-scale applications.

ChainCatcher news, cryptocurrency wallet Trust Wallet released "WASM Vulnerability, Incident Update and Recommended Actions." The announcement states that in November 2022, a security researcher reported a WebAssembly (WASM) vulnerability in the Trust Wallet open-source library Wallet Core through the bug bounty program. The Trust Wallet Browser Extension uses WASM in Wallet Core, and new wallet addresses generated by the Browser Extension between November 14 and 23, 2022, contained this vulnerability. Trust Wallet quickly patched the vulnerability, and all addresses created after these dates are secure.However, Trust Wallet still detected two potential vulnerabilities, which resulted in a total loss of approximately $170,000 during the attacks. In response, Trust Wallet will compensate eligible losses caused by the hacking due to the vulnerabilities and has created a compensation process for affected users. Additionally, Trust Wallet urges affected users to transfer the remaining balance of approximately $88,000 from all vulnerable addresses as soon as possible.Users who only use the Trust Wallet mobile app, only imported wallet addresses into the browser extension, and created a new wallet using the browser extension only between November 14, 2023, and November 23, 2022, are not affected by this vulnerability. If users receive a warning notification in the TW Browser Extension, they may be at risk. Users who experienced unusual fund flows in late December 2022 and late March 2023 may be among the few victims of these two vulnerabilities. (source link)

ChainCatcher news, Astar Network founder and CEO Sota Watanabe announced on Twitter that Astar 2.0 will be launched in the first quarter of 2023. Astar will focus on EVM and WASM in the future, and once Layer 1 is ready, it will deploy Ethereum bridging and Dfinity bridging.It is reported that Astar 2.0 aims to become a multi-chain DApp hub in the Polkadot ecosystem, supporting EVM, WebAssembly, and multiple Layer 1 blockchains. In addition, Astar will also launch a DApp staking feature to provide financial incentives for developers of DApps and infrastructure. (source link)
