GroundX to Bring NFT Activities to 2023 Seoul Light Hangang Bitseom Festival

Seoul’s Seocho District Leverages Blockchain Coins to Catalyze Social ImpactSeocho District, one of the 25 districts in the South Korean capital of Seoul, is leveraging blockchain technology to tackle environmental and welfare issues with the introduction of the “Good Seocho Coins,” as reported by local news outlet Shinailbo.Photo by TANIM MUNSHI on UnsplashContribute and earn rewardsUnder this program, residents of Seocho can earn Good Seocho Coins by engaging in socially beneficial activities. Each coin holds a value of 100 KRW ($0.076) and can be utilized for various purposes such as accessing facilities, enrolling in educational courses, and making purchases at the Seocho Community Center and the Seocho Joongang Senior Welfare Center.From recycling to in-kind donationsTo earn these coins, residents can participate in three categories of activities: recycling, identifying marginalized households, and making in-kind donations. By returning items like paper bags, clothes hangers, empty plastic bottles, and ice packs to 300 Carbon Zero-certified stores within the district — ranging from coffee shops to laundromats and butcher shops — residents can earn coins. For instance, returning ten hangers or empty plastic bottles would earn them a coin.Residents who identify marginalized households and assist them in obtaining welfare benefits will receive ten coins, while those who connect them with social services will earn five coins.Talented individuals can also contribute to the community and earn coins. For example, photographers, hairdressers, makeup artists, and performers of the non-verbal comedy show Nanta can donate their services and earn one coin per hour. Additionally, health educators and volunteers can earn coins by assisting residents aged 60 or older.Expanding horizonsOriginally conceived as an initiative to promote the health and community engagement of elderly individuals, the Good Seocho Coin project underwent revisions last month to encompass a broader community through regulatory changes.Mayor Jun Sung-soo of Seocho District stated that the aim of this initiative is to harness the potential of blockchain technology and motivate district residents to actively contribute towards tackling a wide range of social challenges. He further highlighted the district’s intention to broaden the scope of this initiative in order to cultivate a sense of pride and satisfaction among the residents, leading to a positive ripple effect throughout the community.

OKX Ventures, the investment wing of the Seychelles-based cryptocurrency exchange OKX, has disclosed a strategic A-round investment in Polyhedra Network. Details of the investment have been outlined through a press release published via PRNewswire on Tuesday. Specializing in the creation of Web3 infrastructure, Polyhedra Network places a premium on interoperability, scalability and privacy, leveraging advanced zero-knowledge (ZK) proof technology.Photo by Precondo CA on UnsplashInteroperability with privacyA ZK proof provides the ability for one party to cryptographically prove to another party that it possesses a certain piece of information without having to reveal the actual underlying information to the other party. Central to Polyhedra Network's product offering is its zkBridge protocol, a system facilitating trustless and efficient cross-chain infrastructure for both layer-1 and layer-2 interoperability. The protocol empowers the receiving chain to verify specific state transitions on the sending chain. This approach ensures robust security without external assumptions, effectively reducing the costs associated with on-chain verification. Polyhedra Network made an initial impact in 2023 with the launch of the "zkBridge Mainnet Alpha." That product enabled interoperability over 20 layer-1 and layer-2 blockchains, including well-known networks such as Bitcoin, Ethereum, BNB Chain and Arbitrum. Distributed proof systemThe innovative strides of Polyhedra Network, which was founded in the United States by James Zhang, Tiancheng Xie and Nikhil Shah, continued in 2023 with the introduction of deVirgo, a novel distributed proof system expediting proof generation. The deVirgo protocol also incorporates recursive proofs which trim on-chain proof verification costs associated with zkBridge. Last month, Polyhedra Network unveiled its Bitcoin messaging protocol with zkBridge, ushering trustless interoperability into the Bitcoin ecosystem through the use of ZK-proof technology. Asian backingBy championing entrepreneurs contributing to the blockchain industry's advancement, OKX Ventures is helping to build innovative companies, bringing global resources and historical experience to the forefront of blockchain projects. It is one of many Asia-centric venture firms to do so. Polyhedra has secured backing from Hong Kong’s Animoca Brands and HashKey Group, Singapore’s UOB Venture Management, NGC Ventures, Signum Capital and Foresight Ventures, alongside KuCoin Ventures. In an initial funding round in February 2023, the UC Berkeley team attracted $10 million in funding. By April, a pre-Series A round had raised a further $15 million. Dora Yue, the founder of OKX Ventures, expressed their honor in participating in the investment in Polyhedra Network's interoperability infrastructure. Yue lauded the creativity demonstrated by Polyhedra Network's team in developing advanced ZK-proof mechanisms, emphasizing the balance achieved between ZK interoperability and scalability. OKX Ventures, with an initial capital commitment of $100 million, is committed to supporting Polyhedra Network's vision of seamlessly connecting the Web2 and Web3 worlds, aiming to attract a more extensive user base to the industry. As the investment arm of the global crypto exchange platform, it dedicates itself to exploring top-tier blockchain projects on a global scale. Its focus is on fostering cutting-edge blockchain technology innovation, aspiring to support the healthy development of the global blockchain space and investing in long-term structural value.

Korea unveils detailed plan for retail CBDC transaction pilot with 100K participantsThe Bank of Korea (BOK), Financial Services Commission (FSC) and Financial Supervisory Service (FSS) jointly announced on Thursday (local time) their comprehensive plan to pilot a central bank digital currency (CBDC). This pilot program will concentrate on two key areas: retail transactions and technical experiments within simulated environments.For the retail transaction aspect, the test aims to give citizens direct experience in using the new digital currency, helping them understand its advantages. This practical approach will promote public familiarity with the CBDC.In terms of technical experiments, these will be conducted in partnership with various banks. The goal is to explore and develop methods for constructing a financial market infrastructure suitable for the future, leveraging the capabilities of the digital currency.Photo by Terrence Low on UnsplashRetail CBDC test to commence in Q4 2024The initiative to examine retail transactions using a CBDC is scheduled to begin in the fourth quarter of 2024. This test will focus on improving how vouchers work. Currently, the use of vouchers faces several challenges, such as high fees, complex and slow settlement procedures and the risk of fraudulent transactions. CBDC-based deposit tokens programmed with the digital voucher functionality could help solve these problems. The exploration of digital vouchers within the realm of CBDCs is not just a concern in Korea but also a topic of global interest.Banks that will participate in the CBDC retail transaction test are to be selected by the end of the third quarter of next year, following necessary procedures such as the financial regulatory sandbox policy. These selected banks will receive the green light to issue deposit tokens within this regulatory sandbox framework. They’ll be in charge of recruiting and managing test participants, which includes both individuals and merchants. Additionally, these banks will be responsible for developing digital wallets for users and handling payment transactions. On the other hand, any bank interested in joining technical experiments in simulated environments may apply to do so until mid-December this year.Citizens who want to take part in the retail transaction test for the CBDC can apply through the banks involved in the test. However, it’s important to note that since this CBDC utilization test is a limited trial, the number of participants will be limited to a maximum of 100,000.The retail transaction test for the CBDC will involve three stages: issuance, distribution and payment. Initially, banks will issue deposit tokens with digital voucher functions upon request. Users will then use these tokens to buy goods from merchants, with the transactions being settled accordingly. Before starting, the BOK, FSC and FSS will propose pilot tasks to the banks, following consultations with relevant agencies and the review of pertinent laws. Banks will also propose tasks related to the voucher function. During the test, these tokens will be used solely for digital voucher transactions, and peer-to-peer transfers won’t be allowed.Simulated environment experiments: three use casesFor technical experiments within simulated environments, the financial authorities have selected three use cases focused on examining the technical feasibility of new types of financial instruments.The first objective is to collaborate with Korea Exchange, the only securities exchange operator in the country, to connect the CBDC system with a carbon credit trading simulation platform. This platform will be based on an external distributed ledger. The key objective here is to assess if the “delivery versus payment” (DvP) mechanism between carbon credits and special payment tokens can function smoothly. DvP is a settlement method that ensures the transfer of securities occurs only after the corresponding payment is made.The second objective will see collaboration with the Korea Financial Telecommunications and Clearings Institute (KFTC). In this scenario, a hypothetical issuer will release tokenized assets to the public through a public offering. To manage this, deposit tokens that match the subscription amount by investors will be temporarily frozen, preventing them from being liquidated. After the final allocation of these tokenized assets is determined, the system, using smart contracts, will automatically transfer funds equivalent only to the allocated tokenized assets.The last objective revolves around advancing the concept of a unified ledger introduced by the Bank for International Settlements (BIS). In this endeavor, the BOK aims to issue digital demo securities within the CBDC system. Following this, an experiment will be conducted where financial institutions will have the opportunity to trade these digital securities using the institutional CBDC. This trading will be executed using the DvP method.
