Terraform Labs Co-Founder Daniel Shin Denies Wrongdoing in LUNA Collapse

The U.S. Securities and Exchange Commission (SEC) approved the spot bitcoin exchange-traded fund (ETF) last Tuesday, prompting South Korean investors to flock to cryptocurrency exchanges to make transactions. However, the revenues recorded by these exchanges showed a mixed performance in response to this development due to their differing transaction fee policies, according to local news outlet DealSite on Monday.Photo by Maxim Hopman on UnsplashTrading volumes surge and retreatAccording to crypto analytics platform CoinGecko, as of 9 a.m. on Jan. 12 (KST), Upbit's trading volume on Dec. 11 and 12 was approximately $5.1 billion and $6.1 billion, respectively, for a total of about $11 billion. During the same period, Bithumb recorded $2.6 billion and $2.4 billion, respectively, totaling nearly $5 billion. However, as of this writing at 11 a.m. on Jan. 15, Upbit’s 24-hour trading volume has dropped back down to $2.1 billion and Bithumb to $874 million. "After the SEC's approval, crypto exchanges were simultaneously flooded with transactions," an anonymous industry employee commented. "Bitcoin and Ethereum were mainly traded." Fee divergenceAlthough the ETF approval caused a general uptick in trading volumes, the amount of revenue that the exchanges earned from transaction fees varied. Upbit charges a fee of 0.05% for both buying and selling crypto, meaning the exchange made an estimated KRW 14.8 billion in revenue from the fees from Dec. 11 to 12. Bithumb, on the other hand, hasn't earned any revenue from trading fees since its zero-fee policy was implemented in October last year.  Bithumb had previously charged 0.25% for transactions and 0.04% with coupons. By implementing the former, the exchange lost about KRW 15.8 billion ($12 million) in revenue, and with the latter, it lost about KRW 2.5 billion. For crypto investors, Bithumb's zero-fee policy has made investing more accessible, but the exchange is unlikely to reap its own rewards. Significant investor interestMoreover, with trading for the spot bitcoin ETF beginning on the 11th, the influx of funds is expected to boost trading. "All told there were 700,000 individual trades today in and out of the 11 spot ETFs," Bloomberg ETF analyst Eric Balchunas told X (formerly Twitter). "For context, that is double the number of trades for $QQQ." $QQQ refers to the Invesco QQQ ETF. According to an image that accompanied Balchunas’ post, the total trading volume across all 11 spot ETFs was reportedly $4.3 billion. Grayscale's GBTC had the highest volume at $2.1 billion, followed by BlackRock’s IBIT at $1 billion and Fidelity’s FBTC at $673 million.

Cartesi Launches Inaugural dApp on Ethereum MainnetSingapore-based Cartesi, the app-specific roll-up protocol with a virtual machine running Linux distributions, has introduced its inaugural dApp.The decentralized application, aptly named Honeypot, has been designed to serve as a platform for developers and ethical hackers to rigorously scrutinize the security of the Cartesi protocol’s underlying codebase, all in exchange for lucrative bounties.Photo by Michael Förtsch on UnsplashHoneypot deploymentAccording to a press release published on Tuesday, Honeypot is set to fulfill the vital role of stress-testing Cartesi’s foundational code on the Ethereum mainnet. The successful deployment of Honeypot will pave the way for Cartesi’s technology to be employed in a multitude of other dApps. Notably, a unique aspect of Honeypot is the tempting incentive it offers. The first individual to successfully hack it will be entitled to drain the sum of 1.77 million Cartesi tokens, equivalent to $220,000, after one year without any constraints.Embedded within the Honeypot dApp’s backend code is an algorithm that only permits the Cartesi Foundation’s depositor account to make fund withdrawals. Participants who dare to take on this code-breaking challenge must successfully navigate the intricacies of the algorithm to claim the reward.Developer Advocacy contributor to Cartesi, Gabriel Barros, stated: “We want to welcome all developers to test Cartesi’s Rollup infrastructure — but in a gamified challenge.”Aiding dApp developmentCartesi stands as a Layer 2 network specifically designed to streamline the development of intricate and powerful dApps. Its mission is to bridge the gap between conventional development practices and blockchain-based solutions, attempting to offer a seamless transition for developers.At its core, Cartesi introduces a mechanism that enables dApps to execute resource-intensive computations off-chain within a Linux environment. Crucially, these off-chain computations are verifiable by the blockchain, ensuring that the final results remain consistent across all nodes. This approach empowers developers to harness existing software and tools while ensuring compatibility with the blockchain.Linux insideThe choice of a Linux environment is pivotal to Cartesi’s framework. Linux enjoys widespread usage worldwide, particularly in server environments, making it a familiar and well-adopted platform. This familiarity extends to the extensive array of tools and libraries available within the Linux ecosystem, which are leveraged by developers for a myriad of traditional web applications.Gabriel Barros underlined Cartesi’s mission, stating:“Cartesi’s goal is to eliminate the limitations Web3 developers face by enabling them to import decades of familiar programming tools, libraries, and languages to the blockchain. By doing so, Cartesi unlocks a new realm of possibilities, allowing developers to surpass what was previously imaginable with earlier web3 applications.”Cartesi’s introduction of the Honeypot dApp on the Ethereum mainnet signifies a significant step towards ensuring the security and robustness of its protocol. Furthermore, it demonstrates Cartesi’s intentions in attempting to foster a vibrant and innovative ecosystem for developers in the blockchain space.

Com2uS Holdings, the South Korean game publishing company behind Layer 1 blockchain XPLA, disclosed today that its revenue last year saw a 22.5% increase from 2022, reaching KRW 142.3 billion ($106.7 million). On the back of the revenue growth, the company's consolidated operating loss narrowed to KRW 14 billion, improving from 2022’s KRW 26.4 billion. Additionally, the net loss decreased to KRW 16.5 billion, down from the previous year’s KRW 70.6 billion. The operating loss for the fourth quarter stood at KRW 16.5 billion, showing an improvement from 2022 Q4's KRW 20.9 billion. During the same period, revenue reached KRW 21.4 billion, and the net loss was recorded at KRW 8 billion.Photo by Andrey Metelev on UnsplashGame sales and marketing expensesCom2uS Holdings attributed the increase in profits to game sales growth, which was encouraged by the release of more games. However, the company also noted a decrease in income from investments in associates and an increase in marketing expenses, which were driven by the launch of new games. Last year's operating expenses totaled KRW 156.4 billion. Labor costs, which constitute the largest portion of operating expenses, experienced a year-on-year decrease of 6.2%, amounting to KRW 46.7 billion. In contrast, there was an increase in spending across three areas: commissions rose by 43.8% to KRW 30.7 billion, loyalty expenses increased by 26.6% to KRW 25.1 billion and marketing saw a jump of 134.9% to KRW 21.1 billion. According to a report from local news agency Yonhap, Jung Chul-ho, CEO of Com2uS Holdings, emphasized at the earnings presentation today that the company is committed to growth in game publishing, blockchain projects and platform initiatives, all directed towards enhancing the company's value.Triple-A games on XPLA blockchainAs part of the company’s blockchain endeavors, the XPLA platform is set to focus on improving user convenience and incorporating major content, including a variety of triple-A games. Looking ahead, Com2uS Holdings anticipates that its idle role-playing game, Soul Strike, will contribute to the company's revenue for the first quarter. Since its debut last month, Soul Strike has been attracting attention not only in Korea but across Asia. The game publisher also outlined its global release plans for the MMORPG, Zenonia Chronobreak. Gamers in Taiwan can expect access to the game in the second quarter, while those in Japan and others will be able to play in the fourth quarter.
