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.

South Korean crypto exchanges list USDTBithumb and Coinone, two of South Korea’s largest cryptocurrency exchanges, have recently listed Tether (USDT) — the USD-pegged stablecoin issued by Tether Limited — according to an article by local news outlet Kyunghyang Games on Thursday (local time). Both exchanges support Tether trading on the TRON network.Photo by DrawKit Illustrations on UnsplashTether gains momentum in South KoreaBithumb listed the currency today at KRW 1,316 in response to high investor demand. Meanwhile, Coinone, which listed Tether on Nov. 30 to become the first fiat-to-crypto exchange in the country to facilitate USDT/KRW trading, cited reasons such as Tether’s reliability and transparency, demonstrated by regular updates on its audits and reserves. The listing price was KRW 1,289.Industry sources anticipate that USDT/KRW trading in South Korea will eventually lead to reduced transaction fees and a simplified transaction process for domestic traders. Previously, in order to access most overseas markets where USDT is used as the default currency, users have had to sell their assets overseas first and then repurchase USDT to participate in trading.Simplified transactions are also expected to contribute to balancing pricing across different markets and reducing the Kimchi premium — a term used to describe the difference between trading prices of cryptocurrencies in Korea and in other foreign exchanges.Promotional eventsTo mark the occasion, Bithumb is offering a promotional event where 0.02% of the price of maker orders placed by Dec. 11 will be distributed to users in Bitcoin on Dec. 14. Maker orders are those that are placed at an asking price that differs from the current price, which means it is added to the order book instead of being matched or executed immediately. These orders add liquidity to an order book.Bithumb users can also make USDT withdrawals free of extra fees until Dec. 11. Coinone, on the other hand, requires a withdrawal fee of 1 USDT.According to CoinMarketCap, Tether has the third-largest market capitalization at approximately $90.1 billion as of this writing. The token’s trading volume in the last 24 hours was $49.3 billion.

Newly founded bankruptcy claim trading platform OPNX has provided further details about the entities backing the fledgling startup. Taking to Twitter on Friday, Open Exchange CEO Leslie Lamb outlined a number of venture capital backers, with a mixture of international and Asia-centric firms among them. Global backersLamb’s tweet via the firm’s official Twitter account, together with a similar announcement published to the firm’s website, outlined AppWorks, a leading Taiwanese venture capital firm and startup accelerator, as an investor in the company. Other Asian backers include Hong Kong-based crypto fund, Token Bay Capital and the Hong Kong-based arm of one of China’s largest banks, China Merchant Bank International.With the firm based in Dubai, Middle-Eastern interest is represented through the involvement of Saudi digital asset fund, Tuwaiq Limited. Otherwise, the company lists a number of other international backers, including US equity options exchange MIAX Group, DeFi-focused venture and trading firm Nascent, top tier global venture capital firm Susquehanna and the investment arm of market maker and early stage investor, DRW. Questionable founding teamOnly hours after the disclosure by Open Exchange, DRW reached out to CoinDesk to confirm that it is not an investor in the bankruptcy claims exchange. Nascent and Susquehanna also denied that they are involved. The companies are still being listed by OPNX as backers of the project on its website.The launch of OPNX has been mired in controversy from the outset as its founding team includes the founders of the former crypto hedge fund Three Arrows Capital (3AC) which failed spectacularly in 2022. Su Zhu and Kyle Davies, the founders of 3AC are now the founders behind OPNX. Before their involvement, OPNX was preceded by Seychelles-based crypto yield platform CoinFLEX. That business also failed during the 2022 crypto bear market. It entered into a restructuring process with the consent of the courts in the Seychelles. Emerging from it is OPNX with the 3AC duo of Zhu and Davies having gotten involved at that point. Industry push-backMany in the crypto space have been highly critical of the development of OPNX on the basis of the involvement of both Zhu and Davies. The duo are being blamed for the collapse of the crypto hedge fund due to mismanagement and the knock on effects the firm’s demise had on other entities within crypto. Many of the series of crypto lenders who failed at a later stage in 2022 had major exposure to the wayward hedge fund.There had been some speculation as to who was backing the new project. Earlier this month, BitMEX co-founder and former CEO Arthur Hayes claimed that the 3AC duo had received substantial funding from Bahrain’s sovereign wealth fund to establish the project. In February, Hayes suggested that the crypto bull market must be starting based on news of Zhu and Davies wanting to launch the OPNX platform.Crypto-focused venture capitalist Michael Arrington also spoke out around that time, stating on Twitter, that 3AC founders successfully raising capital for their latest venture was “the saddest bulls**t I’ve heard in a long time.”Upon its launch earlier this month, industry commentators quickly declared the project a flop citing a trading volume of $13.64 on its first day of trading. Five days in, OPNX made light of the situation, declaring a win on the basis that it had progressed to $12,398 in trading volume, representing a 90,000% increase in trading.Dubai’s Virtual Assets Regulatory Authority (VARA) issued an investor and marketplace alert on April 12 stating that while OPNX may be Dubai-based, it is not regulated by VARA and instead operates on an unregulated basis. It warned investors against using any unregulated crypto entity.
