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.

Chung-Ang University to Issue Blockchain-Based CertificatesChung-Ang University, a post-secondary institution in South Korea, on Monday announced plans to implement a system that distributes blockchain-based digital OmniOne badges to students upon accomplishment of tasks such as the completion of courses or extracurricular activities. By doing so, the school aims to leverage blockchain technology to secure digital records of students’ educational backgrounds, thereby creating a more solid foundation for the cultivation of young global talent.Photo by Josefa nDiaz on UnsplashElevating identity verificationThe badges are a blockchain-based software as a service (SaaS) tailored for identity authentication and built on Raon Whitehat’s decentralized identity platform, OmniOne. Raon Whitehat is the blockchain service provider of Korean tech security firm RaonSecure.As a certification tool customized for Chung-Ang students, the badges can showcase progress and achievements in learning, skills, and experience as well as keep records of awards, licenses, and endorsements.“By providing blockchain-powered digital badges, we aim to support individuals in building their expertise and competencies,” said Park Sang-gue, the school’s President.Bringing blockchain technology to the campusThe school said it would run a trial for the system from the end of this month to January next year, then officially implement it starting in next year’s spring semester. It will be applied first to the LG PerfecTwin education curriculum, which the school jointly operates with IT solutions provider LG CNS, and the industrial security convergence program. Students can pass exams and successfully participate in discussions to receive digital badges, which can be managed on the university’s e-portfolio portal.The university also plans to eventually bring the badges to other subjects like artificial intelligence (AI) and the metaverse, then expand the system outside of the classroom so students can use the badges when going through employment processes, academic competitions, and certification acquisitions.Chung-Ang is also working to establish a system where non-fungible token (NFT) degrees and digital badges can be managed together in a single digital wallet. It had formerly worked with Raon Whitehat last year to issue NFT degrees to some 2,000 graduates.Furthermore, the school plans to solidify a support system for global talent development by collaborating with overseas educational institutions and global corporations.“We will provide a safe and convenient learning experience, continuously expand domestic and international partnerships, and create a foundation for students to grow as global talents,” President Park emphasized.

HashKey Report Outlines Risks of Liquid StakingLiquid staking derivatives (LSD) are not without their potential pitfalls according to a report published by Hong Kong’s HashKey Capital.Photo by Shubham Dhage on UnsplashLiquid staking exceeds $22 billionThe report, which was published by the digital asset manager and finance house in July, emphasizes the pressing need for enhanced decentralization to counteract the risks associated with this growing trend of liquid staking.The figures themselves are impressive. This year, the total value locked in the liquid staking derivatives market has surged past the $22 billion mark. Correspondingly, the market capitalization of LSD projects has skyrocketed to $18 billion, indicating a substantial influx of interest and investment.However, the growth that these protocols are witnessing also presents a dual-edged conundrum for the Ethereum ecosystem. HashKey Capital’s report underscores that despite the advantages these protocols might offer their respective communities and token-holders, they could potentially destabilize the Ethereum ecosystem in multifaceted ways.Centralization riskAs evident in HashKey Capital’s overview, several LSD protocols heavily rely on a limited number of node operators, effectively centralizing a significant portion of validator nodes. This centralization trend, as highlighted by the report, is a cause for concern. The concentration of node operators raises red flags, as it contradicts the fundamental tenets of decentralization that underpin blockchain technology.The report articulates the adverse effects of centralization in the realm of liquid staking. It points to the dangers of reduced competition and a heightened risk of censorship.The report raises an important caution: “There is a heightened possibility of censorship with centralized staking players, as they may be subject to incentives or regulatory pressure to censor transactions. This can potentially result in a disruption of the trust within the network.”Security threatsCentralization also ushers in security threats. The dominance of major staking players makes the Ethereum ecosystem more susceptible to 51% attacks. Furthermore, the potential for collusion among centralized stakers looms large, leading to actions that counteract the very essence of decentralization, such as front running and malicious maximal extractable value (MEV) susceptibility.However, amidst these centralization risks, HashKey Capital acknowledges that most protocols are in their nascent stages. Many of them have devised strategies to incorporate distributed validator technology into their protocols, a proactive step towards fostering greater decentralization and resilience.HashKey Exchange awarded retail services licenseIn an unrelated development, HashKey Exchange received approval on Wednesday to upgrade type 1 and type 7 licenses, allowing it to cater to retail investors in Hong Kong. This accomplishment comes a mere two months after the city introduced its Virtual Asset Service Provider (VASP) licensing framework on June 1.In this evolving landscape, HashKey Capital and OSL were among the pioneer licensed exchanges under the city’s earlier voluntary program. Now, the new regulations stipulate that crypto trading platforms must obtain a license to serve retail investors, further solidifying Hong Kong’s commitment to cultivating a thriving crypto ecosystem.As the HashKey Capital report and recent developments in Hong Kong demonstrate, there’s a lot in play relative to both crypto regulation, protocol design and new product innovation. The challenges posed by centralization in liquid staking underscore the importance of vigilance and corrective action. Meanwhile, Hong Kong’s aspirations to become a crypto stronghold offer a beacon of hope in an ever-evolving regulatory landscape.
