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 Japan Exchange Group (JPX), operator of the Tokyo and Osaka stock exchanges, is considering measures to curb the expansion of publicly listed digital-asset treasury (DAT) firms, according to sources speaking to Bloomberg. JPX is reportedly exploring various regulatory avenues, ranging from tightening backdoor listing rules to mandating new audits for applicable firms. Following recent scrutiny from the exchange, three Japanese public companies have suspended their cryptocurrency purchase plans since September. These firms were reportedly warned that pursuing crypto investment as a core strategy could restrict their ability to raise future capital. While JPX currently lacks binding regulations explicitly prohibiting listed companies from accumulating digital assets, a representative stated that the exchange is monitoring firms with potential governance and risk issues to protect the interests of shareholders and investors.Photo by Su San Lee on UnsplashMetaplanet responds to regulatory concernsFollowing the Bloomberg report, Metaplanet, a Japanese public company that has adopted a Bitcoin accumulation strategy similar to that of the American firm Strategy, issued a clarifying statement. The firm asserted that it "has not been subject to any regulatory actions or investigations by relevant authorities concerning our business operations." Metaplanet emphasized its willingness to engage in constructive dialogue with regulators should any inquiries arise.According to BitcoinTreasuries.net data, Metaplanet is currently Japan’s largest corporate Bitcoin holder and ranks fourth globally among public companies, trailing only Strategy, MARA Holdings, and XXI. The extent of the firm’s commitment to this strategy was highlighted by Shinpei Okuno, Metaplanet’s Head of IR and Capital Strategy, who disclosed the company’s holdings via X. Balance sheet data as of September 30, 2025, reveals that Bitcoin accounts for 99% of Metaplanet’s total assets, 542.7 billion yen out of 550.7 billion yen. Okuno noted that the company aims to maintain a balance sheet structure that supports the issuance of digital credits collateralized by its crypto holdings. Market performance and sector outlookThe stock performance of DAT firms highlights the market's reaction to these risks. According to Yahoo Finance, Metaplanet’s share price has declined 40.29% over the past six months to 372 yen. This drop outpaces Bitcoin’s 8% decline over the same period. This downward pressure is visible across the broader DAT sector. Decrypt reported that Strategy's stock has fallen 50% from its July peak, while SharpLink, which invests in Ethereum, has dropped nearly 90%. Data from StrategyTracker indicates that the market-net-asset values (mNAVs) of these firms have slipped to near or below 1, reflecting depressed valuations. Analysts warn that low mNAVs complicate capital raising efforts, potentially forcing these firms to liquidate crypto holdings to cover operating expenses. At the same time, the analysts acknowledged possible tailwinds. Fakhul Miah, Managing Director at GoMining Institutional, told Decrypt that Bitcoin-oriented DATs generally outperform those investing in multiple, higher-risk crypto assets. He suggested that if U.S. economic data indicates easing inflation and the Federal Reserve cuts rates in December, Bitcoin could rally. Yaroslav Patsira, Fractional Director at CEX.IO, echoed this sentiment, noting that the outlook for DATs is tied closely to Bitcoin’s potential upside. Taking a longer-term view, Decrypt noted that despite the recent pullback, crypto-related equities have shown strong year-to-date (YTD) performance relative to the underlying asset.Galaxy Digital is up 73.4% and SharpLink 43.2% YTD, compared to Bitcoin’s 8.6% gain, suggesting the current correction is taking place within a broader uptrend. Japanese stablecoin push faces U.S. resistanceBeyond the equity markets, Japanese crypto initiatives are also encountering regulatory friction in the U.S. Decrypt reported that a coalition of small U.S. banks has formally objected to a bid by Connectia Trust, a proposed subsidiary of Sony Bank, to issue dollar-backed stablecoins in the U.S. Sony Group’s banking arm recently applied to the Office of the Comptroller of the Currency for a national trust charter to facilitate these issuances. The Independent Community Bankers of America (ICBA) argues that the Japanese institution is attempting to exploit regulatory gaps to avoid the oversight applied to traditional banks, noting that Connectia’s stablecoin bears similarities to bank deposits. However, Kadan Stadelmann, CTO of Komodo Platform, offered a different view, telling Decrypt the concerns are “overstated and driven by big-bank interests.” 

Akira ransomware, responsible for stealing $42 million from over 250 organizations across North America, Europe and Australia in just a year, is now targeting businesses in Singapore. In response, Singaporean authorities have issued a joint advisory warning local businesses about the increasing threat posed by a variant of this ransomware.Photo by Mike Enerio on UnsplashAlert follows complaintsThe alert follows multiple complaints from victims, prompting agencies like the Cyber Security Agency of Singapore (CSA), the Singapore Police Force (SPF) and the Personal Data Protection Commission (PDPC) to take action. These agencies emphasize the urgency of recognizing and combating this threat. How Akira operatesAkira affiliates employ various techniques to infiltrate a victim's network. These include exploiting known vulernabilities. For example, that could mean the targeting of services like Cisco virtual private networks (VPNs) that have been configured without multi-factor authentication (MFA). Another approach that the ransomware incorporates is attacking external-facing services such as the Remote Desktop Protocol (RDP) via brute force. Social engineering is another tool within its repertoire. This involves tricking victims into downloading malicious software or entering credentials on phishing websites. There is a marketplace for compromised credentials in the dark web. Akira also relies on such data, acquiring it from access brokers who sell network access.  Once inside a network, Akira affiliates often create new domain accounts to maintain persistent access, even after reboots. They use numerous tools to steal user credentials, escalate privileges and spread throughout the network. Detection and prevention measuresThe Singaporean advisory outlines several strategies for detecting, deterring and neutralizing Akira attacks. Authorities strongly advise against paying ransoms, on the basis that doing so does not guarantee data recovery or prevent future attacks. Authorities also warn that paying ransoms can encourage further attacks. The FBI has noted that Akira operators do not contact victims. Instead, they expect victims to initiate contact. Payment in BitcoinThe advisory outlines how Bitcoin is implicated in the ransomware scam. It states:”Ransom payments are requested in Bitcoin, which are directed to cryptocurrency wallet addresses specified by the affiliates. The TOR site (.onion) where victims contact the affiliates, contains stolen information and a list of the affected organisations.” It’s not the first time that Singaporean authorities have issued warnings that have implicated Bitcoin and crypto. In January, the CSA and SPF, in a joint advisory, suggested that people should use hardware wallets in an effort to guard against crypto-related malware and phishing attacks. A number of weeks prior to that, Singapore’s former Prime Minister, Lee Hsien Loong, took to Facebook to issue a warning with regard to a crypto scam that involved the use of deceptive content generated using artificial intelligence (AI). Mitigation techniquesBusinesses are being urged by the authorities to adopt best practices to mitigate the Akira ransomware threat. They suggest the implementation of a recovery plan alongside the use of multi-factor authentication (MFA) in order to secure data and the access to that data.  They also suggest filtering network traffic as it helps in identifying and blocking malicious activities. Meanwhile, disabling unused ports and hyperlinks curbs the risk further as it reduces the attack surface. Lastly, the authorities suggested the use of system-wide encryption to protect data even if it is accessed by unauthorized entities.
