Incheon City to leverage blockchain for construction transparency

Cronos Labs launches zkEVM chain testnetCronos Labs, the developer behind the Cronos blockchain ecosystem, is charting a new path in the blockchain space by launching a zkEVM chain.From Cosmos to EthereumThe Cronos zkEVM chain is being launched in the first instance as a test network. The layer-2 blockchain will rely upon ZK Stack, the software kit developed by Matter Labs. In this way, the project will be extending its scaling roadmap from Cosmos to Ethereum. As Matter Lab’s SVP of Business and Operations, Marco Cora put it:“When we introduced the ZK Stack, we opened up the door for anyone wanting to build on top of Ethereum to do so by deploying hyperchains. Whether you’re building a specialized Rollup or a general purpose one, hyperchains allow you to tap into Ethereum’s extensive userbase base and liquidity while preserving its robust security and decentralization.”The journey began with the creation of the first chain in the Cronos ecosystem — a Cosmos appchain developed in collaboration with Singapore-headquartered crypto platform Crypto.com and launched in 2021. Subsequently, Cronos introduced an EVM-compatible chain in 2022, built using the Cosmos SDK. Notably, these new endeavors complement, rather than replace, the earlier established chains.Photo by Kanchanara on UnsplashThe product of collaborative effortsA significant development in Cronos’ evolution is the introduction of zkEVM, a result of collaborative efforts involving Cronos Labs, Matter Labs and engineering teams from stakeholders Crypto.com and existing dApp developers. The zkEVM testnet is a breakthrough, utilizing Ethereum’s Sepolia testnet and incorporating zkSync’s open-source prover, Boojum — a STARK-based zero-knowledge proof system known for its efficiency in the layer-2 rollup space, with low hardware requirements and fees.The decision to launch a native Ethereum chain stemmed from challenges in bridging EVM chains and bridging between Cosmos and Ethereum, according to Ken Timsit, Managing Director at Cronos. Timsit emphasized the richness and robustness of the Ethereum developer ecosystem for building DeFi and NFT applications.Native account abstractionHyperchains within the ZK Stack share components, including a native bridge to the Ethereum mainnet and zkSync’s trustless bridging mechanism, ensuring assets remain secured by Ethereum. The implementation of zkSync’s native account abstraction allows transaction fee payments in various cryptocurrencies, including Cronos’ native token (CRO).Cronos’ zkEVM is anticipated to progress to the mainnet in the second quarter of 2024, marking a pivotal moment in the evolution of hyperchains.The landscape of hyperchains is expanding, with projects like GRVT and Tradable utilizing the ZK Stack. GRVT, a derivatives exchange, and Tradable, a tech firm focused on bringing private credit on-chain, exemplify the diversity and specialization within this emerging sector. Tradable aims to establish an institutional-focused hyperchain, potentially forming a decentralized chain alongside other institutional partners.Matter Labs views the zkSync hyperchain as a superior option compared to app-specific chains in Cosmos, emphasizing the scalability and security benefits. Hyperchains, a potential alternative to private blockchain frameworks like Hyperledger or Corda, offer technical scalability with the benefits of Ethereum. However, practical scalability remains a challenge due to cost considerations and the social coordination problem.

The Sandbox Adds Singapore Virtual Neighborhood Lion CityMetaverse platform The Sandbox has announced the launch of Lion City, Singapore’s virtual neighborhood, during its inaugural Singapore Partner Day event.In a blog post published on Tuesday, The Sandbox project team outlined that Lion City is set to debut in September 2023 and will feature 512 plots of virtual land. With over 40 partners and 10+ studios, Lion City aims to showcase global and regional brands, along with established Web3 natives, representing Singapore’s culture in sports, fashion, entertainment, and technology within The Sandbox metaverse.Photo by Kin Pastor on PexelsRegional brand partnershipsThe Sandbox has attracted a range of local partners for Lion City, including MM2 Asia, ONE Championship, Mighty Jaxx Group, Spa Esprit Group, METAVI, Technology Development Centre (TDC) of ITE College Central, UKISS, Bandwagon, Renovi, Affyn, 8sian, The Engineers, Metaskull by Jacky Tsai x Froyo Games, Fabric of Reality, CreativesAtWork, Memotics, FXMedia, Kappou, The Parlour, Manifest, Vaniday, PengWine, LOFI, and Zodium. These partners represent various industries and will contribute to the diverse offerings and experiences within Lion City.Studio partnersMoreover, studio partners catering to the Singapore market will be an integral part of the Lion City experience. These studios include Smobler Studios, CGame Studio, Oceanus Media Global, and iCandy Interactive subsidiaries Lemonsky Studios and Hashcode Studio, New Moon Studios, Pangu by Kenal, and Clevereen. Collaborative ecosystem partners such as OKContract, Pinnacle, DIFY, and Peatix are also contributing to the development of the metaverse.Unlocking Web3 opportunitiesThe Sandbox emphasized the significance of Lion City as a gateway and launchpad for Southeast Asia. With over 400 global brands, including Singapore’s DBS Bank, already on board, Lion City has the potential to unlock new Web3 possibilities in the region. The supportive and collaborative ecosystem in Singapore will provide companies with opportunities to explore digital frontiers and test decentralized technologies.The project also announced the milestone during the Singapore Partner Day event held at the Marina Bay Sands Expo & Convention Centre. The event served as a platform for networking and sharing insights among The Sandbox’s partners.Keynotes were delivered by Sébastien Borget, the Co-Founder and COO of The Sandbox, and George Wong, the project’s Head of Singapore. They discussed the vast opportunities within the metaverse, and panel discussions with ecosystem partners took place, covering topics like intellectual properties (IPs) and the metaverse’s future, as well as the development of the open NFT metaverse.During the event, Borget highlighted Singapore’s regulatory environment, as being conducive to emerging technologies. He also emphasized Singapore’s position as an innovation hub for Web3 advancements.The metaverse faces new challenges in 2023, with the crypto market gravitating towards a more institutional-friendly approach, and questions surrounding its relevance. Recently, Borget had a clash with the SEC in the United States, disagreeing with the regulator’s classification of the project’s native $SAND token as a security.No doubt that experience has helped to underscore his appreciation for Singapore’s regulatory setup. Nevertheless, Wong described 2023 as an important and pivotal year for metaverse growth.

At Hong Kong FinTech Week 2025, Securities and Futures Commission (SFC) Chief Executive Julia Leung outlined plans to link Hong Kong’s crypto market with global liquidity. She announced that licensed virtual asset trading platforms (VATPs) will be allowed to share a global order book with their overseas counterparts. According to a statement published on the SFC’s website, this step will enable local investors to access international markets more efficiently, improving price discovery and competitiveness. Leung added that more initiatives are on the way to connect local brokers directly to global liquidity networks. This latest connectivity push comes as Hong Kong considers new guardrails for crypto holding companies such as digital asset treasuries (DATs), which hold cryptocurrencies as strategic assets.Photo by Manson Yim on UnsplashSFC points to regulatory gaps for digital asset treasuriesThe state-owned newspaper Wen Wei Po reported that Securities and Futures Commission (SFC) Chairman Kelvin Wong noted the current lack of regulations governing listed companies operating as DATs and the limited understanding of such entities. Chairman Wong added that firms seeking to list in Hong Kong as DATs would need to persuade both the SFC and the Hong Kong Stock Exchange (HKEX) of their suitability. For companies already listed, he urged investors to remain alert to the potential risks involved. This regulatory concern over crypto investing companies emerges as Hong Kong simultaneously presses ahead with its ambition to become a leading hub for digital finance. City advances on e-HKD and tokenizationIn line with that ambition, the Hong Kong Monetary Authority (HKMA) unveiled its e-HKD Pilot Programme Phase 2 Report in an Oct. 28 press release. The report outlines the potential benefits of its central bank digital currency (CBDC), the e-HKD, and tokenized deposits, noting that public feedback on both concepts has been broadly positive. The program's second phase involved 11 pilot projects led by various consortiums. These projects explored retail use cases, emphasizing the e-HKD’s commercial viability and scalability. Key focus areas included the settlement of tokenized assets, programmability, and offline payments. Participants in the program included Aptos Labs, the Boston Consulting Group (BCG), Hang Seng Bank, Standard Chartered, and BlackRock. Based on the report's findings, the HKMA stated it would initially prioritize the e-HKD’s application in wholesale or large-value payments, leveraging its credit risk–free nature as a central bank liability. Concurrently, the authority plans to continue studying potential retail and corporate applications, aiming to lay the groundwork for broader implementation by the first half of 2026. Survey shows strong investor appetiteAmong the program’s participants, Aptos Labs, Boston Consulting Group (BCG), and Hang Seng Bank reported accelerating interest in tokenized funds. A survey they conducted found that 61% of retail investors in Hong Kong and mainland China planned to double their exposure. Held between May and June 2025 among more than 500 retail fund investors, the survey tracked sentiment and appetite for tokenized products. Mainland participants showed particularly strong demand for cross-border access. The findings also detailed differing motivations among Hong Kong investors. Active traders expect to lift tokenized fund allocations from 10% to 26%, attracted by round-the-clock trading and greater flexibility. Wealth transfer planners indicated an expected expansion from 5% to 16%, highlighting programmable fund structures for tailored trusts and transparent oversight. Long-term investors aim to raise exposure from 8% to 25%, citing instant liquidity and the ability to use tokenized assets as loan collateral. Mainland investors projected their allocations would climb from 11% to 24%, reportedly viewing tokenized funds as a practical route around capital restrictions. The survey noted that programmable features could support dynamic allocation across Hong Kong products, the onshore use of profits, and smoother cross-border transfers. BCG commented that the survey outcomes align with Hong Kong's measured advance in crypto oversight, pointing to the city’s stablecoin regime that came into force in August. The Hong Kong Monetary Authority (HKMA) has signaled, however, that licensing under that regime will not begin until early next year. The ongoing development of the e-HKD and the prospective regulation of digital-asset treasuries point to Hong Kong’s broader strategy of integrating digital finance into its mainstream economy. Together, these initiatives underscore a cautious yet steady effort to position the city as a global center for digital finance.
