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.

Uzbekistan’s New Private Bank Joins National Crypto Card InitiativeIn a step towards enhancing its cryptocurrency ecosystem, the Republic of Uzbekistan has given the green light to include another private bank in its ongoing national crypto card project. The development was announced through an official press release earlier this week by the National Agency of Perspective Projects (NAPP), the country’s regulatory authority for digital assets.Photo by engin akyurt on UnsplashBuilding upon a crypto frameworkUnder the provisions outlined by the Uzbekistan Ministry of Justice on December 30 of last year, the Special Regulatory Sandbox Regime was established. This unique framework empowers specific entities within Uzbekistan’s crypto sphere to provide specialized services. JSV Ravnaq Bank has now been registered as a member of this regime, enabling its active participation in the pilot phase of the nation’s crypto card project.Virtual bank cardThis initiative is poised to introduce a virtual bank card named “CRYPTO CARD — UzNEX.” The card’s standout feature is its ability to facilitate automatic fund addition to users’ primary accounts. This is achieved by swiftly converting crypto assets from a digital wallet on a partner crypto exchange platform.A vital aspect of the crypto card’s development lies in its compatibility testing with various financial systems, including the widely used Mastercard payment platform. According to NAPP’s statement, the participant bank within the special regulatory regime will be rigorously testing the integration of the automated banking system, crypto-exchange information system, bank processing center, and the MasterCard international payment system.December launchNotably, the addition of Ravnaq Bank marks the second entrant into the project, with Kapital Bank being the first participant approved in May. While Kapital Bank’s testing phase commenced at the end of June 2023, Ravnaq Bank is set to initiate its test launch by the end of October 2023. Both banks are expected to launch the full project by late December, in accordance with NAPP’s timeline.Beyond these private banks, the Special Regulatory Sandbox Regime also includes UZINFOCOM, a company authorized to develop NFT certificates based on distributed data registry technology.

South Korea’s retail-heavy crypto market is losing momentum ahead of broader institutional access to trading. Data from the Financial Services Commission (FSC) and the Financial Supervisory Service (FSS), cited by Financial News, shows that in the first half of 2025, Korean-won balances held at the country’s five licensed fiat-to-crypto exchanges sank 42% to 6.2 trillion won ($4.4 billion), signaling less dry powder waiting on the sidelines for trading. Only five platforms are permitted to support won-denominated trading, and the drop in parked cash underscores a broader cooling. By the end of June, the Korean crypto market cap stood at 95.1 trillion won ($67.5 billion), down 14% from six months earlier. The global market also contracted, but the decline was more modest at about 7% over the same period.Photo by Y K on UnsplashTrading slows but retail base expandsTrading activity eased as well. Average daily volumes across 25 domestic virtual asset service providers (VASPs) fell 12% to 6.4 trillion won ($4.5 billion) in the first half. Paradoxically, the number of market participants climbed 11% to 107.7 million across those platforms. Nearly all were individuals, as only 220 were institutions, reflecting long-standing restrictions on institutional won trading. That retail skew has consequences. Data submitted by the FSS to a lawmaker, cited by Digital Asset, reveals that the top 10% of users by trading volume accounted for roughly 90% of activity at the five fiat on-ramps. By exchange, the figures were Upbit (89.36%), Bithumb (97.97%), Coinone (97.54%), Korbit (97.52%), and Gopax (97.95%).  Market lawyers warn that this concentration heightens manipulation risk. Lee Seung-min of SEUM Law Firm said volatility may be more pronounced in tokens listed only on Korean venues, but added that deeper institutional participation could help reduce such volatility and support longer market cycles.  Regulators are inching in that direction. Earlier this year, authorities allowed universities and nonprofits to sell their crypto holdings. By year-end, the FSC plans to let about 3,500 publicly traded companies and professional investors, excluding financial institutions, open accounts at the licensed platforms for trading. Exchanges pour cash into promotionsWhile regulators are preparing to bring more institutional players into the fold, exchanges continue their long-running effort to draw in retail users. Another Digital Asset report noted that from 2023 through July 2025, promotional outlays by the five won-enabled platforms totaled 190.3 billion won ($135 million). Bithumb alone accounted for 180.3 billion won ($128 million), far outspending Upbit (9.4 billion won), Coinone (1.7 billion won), Korbit (1.6 billion won), and Gopax (100 million won). The gap suggests Bithumb, which ranks second in market share, has pursued a particularly aggressive approach to expand its customer base. Taken together, the numbers depict a subdued market, with less capital parked on exchanges and lighter trading while activity remains heavily concentrated among a small cohort of traders. Even so, the expanding base of individual accounts represents a bright spot, underscoring the market’s continued dependence on retail investors. If policymakers follow through on opening the door to a broader set of corporate and professional players later this year, Korea’s crypto landscape could shift from retail-driven fluctuations toward steadier, institution-supported flows.
