Korean Blockchain Experts Suggest Tackling Everyday Challenges with Blockchain Adoption

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.

Ethereum Co-Founder Highlights User-Friendly Crypto Wallets at Ethcon Korea 2023Ethereum co-founder Vitalik Buterin delivered a keynote speech last Friday at Ethcon Korea 2023 — a hackathon and conference sponsored by Ethereum for the Korean Ethereum community in Seongsu-dong, Seoul — where he emphasized the importance of making crypto wallets user-friendly by striking a balance between user familiarity and decentralization.Photo by Nenad Novaković on UnsplashEnhancing security and convenienceParticipating in the event via video call, Buterin explained Ethereum’s ERC-4337 account abstraction upgrade during his speech, which was livestreamed on the Ethcon Korea YouTube channel. “The goal of account abstraction — a field that many wallets are currently working on developing — can be broadly categorized into two areas: security and convenience,” he said.Deployed on the Ethereum mainnet in March, the ERC-4337 is a standard that makes it possible to transact and create contracts in a single contract account, paving the way for more user-friendly crypto wallet designs. At its core are features such as easy account recovery, improved security, and customized services like auto-pay and bundled transactions. This provides a more convenient alternative to other crypto wallets, which mostly rely on private keys for account access, complicating setup and recovery procedures especially if a user loses their seed phrase.“Wallets must fundamentally be secure in a decentralized way, but there should also be ways to recover passwords as hardware wallets do,” Buterin stated. “However, many projects still rely on methods such as account recovery via email.”Simplifying transactionsAnother change introduced through the update is gas flexibility. Gas is a fundamental fee that users must pay to conduct transactions or execute a contract on Ethereum. Wallets backed by ERC-4337 can pay gas fees with any Ethereum utility tokens and more, including USD coins (USDC).From a convenience standpoint, Vitalik argued, it is very useful for first-time Ethereum users to be able to pay for gas with the USDC they already have. Sponsored transactions, where applications pay for fees, will be a great way to attract new users, especially for non-financial applications.He further elaborated that in order to transition from being user-friendly but centralized to more decentralized, a combination of a faster but precarious centralized approach with a slower but safer decentralized approach is required.He also stressed the importance of utilizing the various options available in modern technology concerning convenience, security, and decentralization, saying that it is essential to utilize these options effectively, continuously improve them, and take advantage of the benefits.Since 2019, Buterin has used Ethcon as a platform to announce Ethereum’s development roadmap and major technical updates.

South Korea’s central bank, the Bank of Korea (BOK), plans to begin testing peer-to-peer (P2P) transactions with its central bank digital currency (CBDC) in October, according to the Seoul Economic Daily. This will mark the second phase of its ongoing CBDC pilot, Project Hangang, which currently allows 100,000 citizens to use digital tokens for payments at both online and offline stores. In the fourth quarter, the pilot will also introduce voucher programs enabling local governments to distribute welfare benefits.Photo by Mathew Schwartz on UnsplashSandbox deadline pressureThe BOK originally planned to gather feedback from participants in the first phase and refine the system before proceeding. However, the central bank decided to speed up the timeline, as the broader project is operating under a regulatory sandbox program that provides two years of regulatory flexibility. A BOK official noted, “Since the current test ends in June, we can’t wait too long to move forward. Also, the fourth quarter timeline is still tentative.” While the BOK focuses on its CBDC, Korean commercial banks are accelerating efforts to develop stablecoin infrastructure and launch related pilot projects, Edaily reported. These initiatives reflect growing expectations that stablecoins will become a key tool for cross-border payments. Banks see this as an opportunity to attract new customers and earn fees from crypto exchanges by facilitating stablecoin transfers through their own networks. One example is Project Pax, a joint initiative involving Shinhan Bank, Nonghyup Bank and Kbank, which is testing stablecoin transfers between South Korea and Japan. Led by Japan’s digital asset platform Progmat, along with Korea’s Fair Square Lab and Korea Digital Asset Custody, the project enables Korean banks to send won-based stablecoins to Japanese financial institutions and receive yen-pegged stablecoins in return. Rising stablecoin useAn executive at a local bank expressed concern that South Korea is falling behind in stablecoin adoption. He predicted faster uptake, noting that consumers can save time and money by avoiding traditional foreign exchange processes. He also cautioned that, without action, the private sector could take the lead in building cross-border payment networks, bypassing the traditional SWIFT system. Another banker urged financial authorities to establish clear regulations for stablecoins, stressing the need for oversight as stablecoins are increasingly used to move foreign currencies out of Korea. Contrasting perspectivesHowever, BOK Governor Rhee Chang-yong remains skeptical of stablecoins, arguing that CBDCs offer far greater transparency. He pointed to the volatility of unregulated stablecoins and warned that their widespread use—especially if issued by private financial institutions—could undermine the central bank’s role as the sole issuer of legal tender. That said, financial authorities appear to be exploring a regulatory framework where CBDCs and stablecoins can coexist. Sharing his personal view, one official noted that while the future of stablecoins is uncertain, it’s important to remain open to various possibilities. He added that agencies are also reviewing recent changes in U.S. federal law, along with regulations in Japan and the EU.
