Scroll’s zkEVM Launches on Ethereum MainnetScroll, the Seychelles-headquartered project behind the Ethereum layer-2 network of the same name, has officially made its debut on the Ethereum mainnet.Photo by Zoltan Tasi on UnsplashAttempting to solve for scalabilityThe project team announced the development via a press release which was published on Tuesday. The network launch signifies the latest in a series of attempts by various layer-2 projects, including Polygon and StarkWare, to address the persistent challenges of high transaction fees and network congestion that have hindered Ethereum’s usability in recent times. Speaking to layer-2 development, co-founder Sandy Peng stated:“We see a future where the vast majority of value transfer takes place on Layer 2s on Ethereum. What will drive that adoption is improved user and developer experience.”After testing and refinement on its testnet, Scroll believes that it is in a good position to play an active role within the Ethereum ecosystem by providing a general-purpose, zero-knowledge Ethereum virtual machine (zkEVM) roll-up.The project has 900,000 wallet addresses in active use on its testnet, having executed seven million transactions since August. The testnet has seen over 55 million transactions during its year-long operation.At its core, Scroll’s mission is to combine Ethereum’s network security with reduced fees and lower latency, making it an attractive proposition for existing Ethereum projects. According to Peng, Ethereum developers can seamlessly deploy their projects on Scroll and harness the groundbreaking zkEVM technology.Incorporating bytecodePeng emphasized the significance of zkEVM’s ability to batch proofs efficiently, resulting in faster transaction speeds and cost reductions, thanks to its bytecode-level compatibility.Bytecode, in the realm of computer programming, simplifies intricate machine cryptography, making code more accessible for computer hardware. Scroll allows deployed smart contracts to store the bytecode of their transactions, which is then sent to a centralized zkEVM node. This node verifies the transaction’s accuracy without revealing its content. Once verified, the transaction’s status is updated on the Ethereum network, eliminating the need for re-execution. Peng pointed out:“Thanks to this feature, Ethereum devs can leverage all the same tools they are familiar with, ensuring that everything operates seamlessly right from the start.”Scroll’s mainnet code was subject to audits conducted by four major auditing firms, namely Zellic, Trail of Bits, OpenZeppelin, and KALOS, in an effort to ensure robust security and reliability.Efforts towards greater decentralizationWhile Scroll’s current implementation offers compelling features, the team is actively researching ways to further enhance the network’s decentralization. Currently, if the sequencer goes offline, the protocol halts, creating a potential vulnerability. To address this, the Scroll team is working on a protocol upgrade that will enable “forced batches.” This update will allow permissionless publication of batches through the base layer, even in the event of a sequencer halt.Peng elaborated on the team’s vision, stating: “Mid-term, the goal is to minimize the probability of a sequencer halt through decentralization.” This approach aims to bolster the network’s resilience and ensure a smoother user experience.While headquartered in the Seychelles, the project has its origins in China through its Chinese founders, Ye Zhang and Haichen Shen, alongside Peng, with many of its 60-strong project team based in mainland China and Hong Kong.

WEMIX Foundation launches omnichain walletThe WEMIX Foundation, a subsidiary of South Korean blockchain gaming publisher Wemade, has officially launched the una Wallet, according to an official announcement on the company’s website on Thursday (KST). una Wallet is a core application of the Unbound Networking & Accelerating Growth Initiative, or “unagi,” the company’s newest innovative omnichain network and interoperable Web3 gaming platform.Photo by Shubham’s Web3 on UnsplashEasy asset managementThe wallet service offers a solution for users to conveniently earn, manage and trade their digital assets like NFTs and tokens on multiple blockchains — such as WEMIX3.0, Ethereum and Polygon — in one borderless place. The WEMIX Foundation said it would add more supported chains in the future.Effortless access and robust securityIn particular, una Wallet’s convenience and security stem from an easy login procedure utilizing connections to social media accounts and multi-party computation (MPC) technology. MPC is a cryptographic security measure that enables multiple parties to assess a computation without revealing their private information or data. This technology splits private keys, or mnemonic phrases, and allows users to easily recover their wallets through social login even if they lose their keys.The service also provides transaction route recommendations, allowing users to move or trade assets across chains with minimal costs or signature procedures. Subsequently, they can also view their transaction history on each chain and the movement of assets between different chains.WEMIX plans to add various features to make authentication and asset-tracking processes even easier. una Wallet is currently available on Google Play and the Apple App Store.

South Korean Job Seekers to Benefit from Digital Badges for License CredentialsSouth Korean job seekers will soon be able to enjoy the convenience of proving their license credentials with digital badges based on non-fungible tokens (NFTs).The South Korean Ministry of Employment and Labor has announced that its affiliate, the Human Resources Development Service of Korea (HRDK), plans to create a mobile application that supports virtual asset wallets. These wallets will allow citizens to conveniently store their HRDK-issued licenses in the form of digital badges.Photo by Gül Işık on PexelsNFT-based digital badgesThese digital badges, which are based on NFTs, will also serve as proof of certification for HRDK’s education and training courses. Decentralized identifiers (DIDs) based on blockchain technology will prevent forgery and counterfeiting and improve personal information protection. The incorporation of gaming elements within NFTs is expected to motivate citizens to engage in continuous learning.Chosen as this year’s state-led blockchain initiative last December, the digital badge project is supported by the Ministry of Science and ICT (MSIT) and the Korea Internet and Security Agency (KISA). HRDK aims to complete the transformation of its 18.5 million issued licenses into digital badges by the end of this year. The project also involves digitizing vocational training certificates issued by the Korea Employment Information Services (KEIS), which has an average annual issuance of 3.6 million certificates. Access to these badges will also be facilitated through not only state-managed mobile ID wallets but also private platform wallets.In the context of employment and career management, individuals have traditionally received paper certificates and had to deliver them to relevant organizations. This process often involved inconvenience, as it required in-person visits, mailing, or scanning. Moreover, individuals faced the hassle of repeatedly obtaining the same certificate due to expiration dates and storage concerns.Seamless certificate managementWith the introduction of the digital badge service, users will be able to download a mobile application on their smart devices. This app will enable them to access their national certificates, allowing them to view their qualification and training completion information at any time. Additionally, users will gain the convenience of instantly submitting or verifying their certificates remotely through their mobile devices whenever necessary.HRDK will further enhance its services through strategic partnerships with credentialing organizations from both the public and private sectors.Kim Young-joong, the Acting President of HRDK, emphasized the significance of national licenses and training certificates as objective measures of individuals’ performance and skills, underscoring their importance in the employment landscape. He further expressed HRDK’s commitment to ensuring customer satisfaction by leveraging cutting-edge technology and efficient data management practices to drive innovation in public services.
