K-pop fans enjoy collecting photo cards featuring their favorite singers or actors, and thanks to blockchain technology, these cards can now be transformed into non-fungible tokens (NFTs), ensuring their authenticity and preventing forgeries and counterfeits. Dunamu’s blockchain expertise has combined with HYBE’s intellectual property to create a range of collectible items for K-pop fans.In a recent interview with Donga Ilbo, Levvels CEO Cha Sang-hoon explained the company’s current status and future plans. Cha said that Levvels is primarily a blockchain-based Web3 company aiming to leverage various technological tools to offer a range of services.Levvels’ Momentica issues digital photo cards called TAKEs, which capture unique and memorable moments of artists, and the collection, appreciation, and trading of these cards are facilitated through the Momentica app. Fans can use Momentica to collect digital cards featuring artists such as Seventeen, Le Sserafim, and Fromis_9. The authenticity of TAKEs is verifiable, as they are recorded on the blockchain.© Pexels/Sebastian ErviPhysical to digitalMomentica transitions the fan experience from the physical world to the digital realm. Through the app, K-pop aficionados can now exchange photo cards, promote their favorite stars, and maintain a virtual album. Exclusive content, including pictures, videos, and handwriting from some artists, will be available only on Momentica.Cha mentioned that Momentica has users across 93 countries, with Koreans constituting 40% of the total. Japanese users represent over 30%, indicating the app’s strong presence in the Japanese market. Taiwan, Indonesia, and the US follow in the number of users. Overall, the app’s popularity aligns with regional interest in K-pop.Beyond HYBEWhile the current service focuses on limited collections of digital photo cards, Momentica plans to enhance the experience by allowing K-pop fans to personalize and directly exchange cards. The company is also working on collaborations with artists from labels beyond HYBE for them to participate in Momentica.

MAS and NY Fed Publish Report on CBDC Cross-Border PaymentsNew York’s Federal Reserve Bank and the Monetary Authority of Singapore (MAS) have collaborated on an endeavor titled “Project Cedar Phase II x Ubin+,” examining the use of a central bank digital currency (CBDC) for wholesale cross-border payments using one or more vehicle currencies.The joint effort has culminated in the publication of a report detailing their findings and results. Commenting on the initiative, MAS Managing Director Leong Sing Chiong stated:“The Cedar x Ubin+ experiment envisages a future digital currency landscape where central banks can enable interoperability of wholesale CBDCs to facilitate more efficient cross-border payment flows including for less liquid currencies, without requiring a common infrastructure.”Photo by NASA on UnsplashExploiting positive DLT characteristicsSpecifically, the New York Innovation Center (NYIC) of the NY Fed was the entity that contributed directly towards the research project. The work built on previous phases of Project Cedar. The objective was to explore perceived advantages of digital ledger technology (DLT) such as reduced settlement risk and reduced settlement time, in the context of cross-border payments.The conventional system primarily uses the SWIFT financial messaging network. The approach is highly inefficient. It’s time-consuming and needlessly ties capital up in vostro and nostro accounts (accounts held for another entity from an account another entity holds). Tying up capital proves to be a liquidity headache for corporations and any business entity that gets involved with international trade settlement.Smart contracts and off-chain messagingAgainst that backdrop, the project team was focusing on harnessing the ability to effect atomic or real-time settlement using DLT. Having commenced the work in November, the project team decided to rely on hashed timelock smart contracts in order to bridge distinct ledgers, so as to effect cross-currency and cross-border transactions.According to the report, the proposed system also relied on off-chain messaging functionality. Cross-border trade settlement often involves a number of stakeholders. Off-chain messaging can be beneficial in disseminating information relative to the process to all stakeholders.The researchers found that each simulated payment scenario achieved end-to-end settlement in under thirty seconds on average, realizing the goal of near real-time settlement. In turn, that speed of settlement meant that stakeholders could be notified of payment finality within a matter of seconds. Certainty of settlement, and thus reduction in counterparty risk was achieved by simulating atomic settlement, such that transactions only settled if all legs in the cross-currency payment chain executed successfully.From the point of view of interoperability and autonomy, the experiment demonstrated the ability to safely execute across multiple ledgers without the need to involve a centralized clearing authority or the establishment of a shared central network.The Bank of International Settlement (BIS) recently highlighted the finding that on a daily basis, $2.2 trillion of foreign exchange transactions don’t use a payment versus payment (PvP) settlement mechanism. PvP is a less risky form of settlement where two currency legs are exchanged simultaneously. Singapore is more exposed than most in this regard. Therefore, the use of DLT to counteract that risk in line with the experiment’s findings would be a progressive step.

GRVT Debuts zkSync’s Inaugural ‘Hyperchain’GRVT, the hybrid crypto exchange incorporated in the British Virgin Islands, is all set to debut as zkSync’s inaugural “hyperchain,” marking a significant milestone in the zkSync ecosystem’s evolution.zkSync represents Ethereum’s second layer solution offering cheaper and faster transactions.Photo by Shubham Dhage on UnsplashCombining CEX and DEX qualitiesPronounced “gravity,” GRVT is an innovative platform that attempts to seamlessly blend the advantages of centralized and decentralized exchanges. It promises users a Robinhood-like experience while integrating self-custodial features akin to Uniswap-style exchanges. Matter Labs, the developer brains behind zkSync, shared news of GRVT's imminent project milestone in an interview with The Block.The introduction of GRVT as the first Hyperchain within the zkSync ecosystem has broadened the horizons of potential applications for this technology, according to Matter Labs. The project stated:“There is nothing like GRVT being built, not in the zkSync ecosystem nor outside of it. By being able to design and deploy custom hyperchains connected through hyperbridges, teams like GRVT’s can build entirely new use cases.”The ability to design and deploy custom hyperchains connected via hyperbridges opens the door to entirely new use cases, affording projects like GRVT the freedom to explore innovative possibilities.A layer 3 ValidiumGRVT will play a role as a Layer 3 Validium within the zkSync ecosystem. Validiums are Ethereum scaling networks that bear similarities to zk-rollups found in Layer 2 solutions. The critical differentiator is in how they handle data. Zk-rollups maintain data on-chain, whereas Validiums securely store it off-chain. This approach enhances user security by safeguarding against front-running and market manipulation.GRVT’s alpha version is set to make its debut next month, followed by the mainnet release in the first quarter of the upcoming year. Promising a transaction speed of up to 600,000 trades per second and less than two milliseconds of latency, GRVT leverages zkSync’s “horizontally scaling” infrastructure to deliver enhanced performance.Explaining the concept of horizontally scaling, Hong Yea, GRVT’s co-founder and CEO, told The Block:“Horizontally scaling means to deploy additional underlying pairs as new hyperchains. Say BTC/USDT perpetual futures is one hyperchain and so on. And we can look to add other infrastructure components like this as new hyperchains to scale throughout, as they can interoperate. This allows high-frequency traders to trade more efficiently with high transactions per second similar to a central exchange.”Token launchGRVT enjoys the backing of CMS Holdings, Hong Kong’s digital assets wealth manager Metalpha, alongside Matter Labs and others. Yea founded the company alongside CTO Aaron Ong and CCO Matthew Quek. Although incorporated in the British Virgin Islands, the firm employs people who are based in Hong Kong, the UK, Lithuania, and Singapore.It recently disclosed that it had successfully raised $7.1 million in pre-seed and seed funding in an equity with a token warrant round, achieving a $39 million post-money valuation. The launch of GRVT’s token is anticipated in 2024.GRVT is also making a concerted effort to obtain trading licenses in various jurisdictions. Currently, it has attained a virtual asset service provider (VASP) license in Lithuania, with work ongoing to achieve licensing in Bermuda. The firm hopes to then expand in Europe and the Middle East going forward.
