Japan Tops Crypto Losses to North Korean HackersHackers affiliated with the North Korean regime have been responsible for the theft of $721 million in digital assets from Japan.That’s the finding of a recent report by UK-based crypto compliance analysis firm Elliptic. Elliptic had produced the report on behalf of Japanese news media group, Nikkei. It leaves Japan at the top of the table when considering the distribution of digital asset losses suffered due to North Korean hackers on a country by country basis.Photo by FLY:D on UnsplashIncreasing lossesElliptic has the wherewithal to track and identify blockchain-based transfers. As part of its analysis, it grouped by region and by country those businesses that it identified as having cryptocurrency holdings that later were transferred to digital wallets held by the Lazarus Group, the most notorious hacker group connected with the North Korean government. It’s the first such analysis to break down crypto-related hacking losses on a country by country basis.The study included a consideration of both hacking and ransomware attacks. The loss associated with Japanese-based entities represents in excess of 30% of the global recorded loss. This latest analysis follows a recent report submitted to the United Nations which found that North Korea stole more digital assets in 2022 than any other year. That report had been submitted to the 15 members of a North Korea sanctions committee, finding that between $630 million and $1 billion worth of digital assets had been stolen.Lax securityElliptic’s analysis and subsequent report point to lax security being employed within Vietnamese and Japanese cryptocurrency marketplaces. Nikkei referred to an unnamed source who asserts that at least three Japanese cryptocurrency exchanges had been compromised by hackers between 2018 and 2021.One of those instances involved Zaif, a company that lost $51.4 million in 2018 and subsequently shut down operations. Overall, Elliptic estimates a global loss of $2.3 billion to hackers between 2017 and 2022 in digital assets, as suffered by crypto firms. It also estimates such losses suffered in the United States at $497 million, while Hong Kong-based losses have been calculated at $281 million.International responseIn April, the Office of Foreign Assets Control (OFAC) within the Department of the Treasury in the United States stated that it had sanctioned two Chinese nationals and a Hong Kong British national for allegedly having aided the North Korean government in crypto money laundering activities.On Saturday, a joint statement was issued by the Group of Seven finance ministers and central bank governors, following a meeting in Japan, outlining the “growing threat from illicit activities by state actors.” It’s widely believed that the proceeds of these hacks are contributing towards the funding of North Korea’s missile program and other such activities that threaten stability within the region.The Japan External Trade Organization (JETO) has estimated that the estimated $721 million stolen from Japan amounts to 8.8 times the value of North Korea’s exports in 2021.

Scroll’s zkEVM Launches on Ethereum MainnetScroll, the Seychelles-headquartered project behind the Ethereum layer-2 network of the same name, has officially made its debut on the Ethereum mainnet.Photo by Zoltan Tasi on UnsplashAttempting to solve for scalabilityThe project team announced the development via a press release which was published on Tuesday. The network launch signifies the latest in a series of attempts by various layer-2 projects, including Polygon and StarkWare, to address the persistent challenges of high transaction fees and network congestion that have hindered Ethereum’s usability in recent times. Speaking to layer-2 development, co-founder Sandy Peng stated:“We see a future where the vast majority of value transfer takes place on Layer 2s on Ethereum. What will drive that adoption is improved user and developer experience.”After testing and refinement on its testnet, Scroll believes that it is in a good position to play an active role within the Ethereum ecosystem by providing a general-purpose, zero-knowledge Ethereum virtual machine (zkEVM) roll-up.The project has 900,000 wallet addresses in active use on its testnet, having executed seven million transactions since August. The testnet has seen over 55 million transactions during its year-long operation.At its core, Scroll’s mission is to combine Ethereum’s network security with reduced fees and lower latency, making it an attractive proposition for existing Ethereum projects. According to Peng, Ethereum developers can seamlessly deploy their projects on Scroll and harness the groundbreaking zkEVM technology.Incorporating bytecodePeng emphasized the significance of zkEVM’s ability to batch proofs efficiently, resulting in faster transaction speeds and cost reductions, thanks to its bytecode-level compatibility.Bytecode, in the realm of computer programming, simplifies intricate machine cryptography, making code more accessible for computer hardware. Scroll allows deployed smart contracts to store the bytecode of their transactions, which is then sent to a centralized zkEVM node. This node verifies the transaction’s accuracy without revealing its content. Once verified, the transaction’s status is updated on the Ethereum network, eliminating the need for re-execution. Peng pointed out:“Thanks to this feature, Ethereum devs can leverage all the same tools they are familiar with, ensuring that everything operates seamlessly right from the start.”Scroll’s mainnet code was subject to audits conducted by four major auditing firms, namely Zellic, Trail of Bits, OpenZeppelin, and KALOS, in an effort to ensure robust security and reliability.Efforts towards greater decentralizationWhile Scroll’s current implementation offers compelling features, the team is actively researching ways to further enhance the network’s decentralization. Currently, if the sequencer goes offline, the protocol halts, creating a potential vulnerability. To address this, the Scroll team is working on a protocol upgrade that will enable “forced batches.” This update will allow permissionless publication of batches through the base layer, even in the event of a sequencer halt.Peng elaborated on the team’s vision, stating: “Mid-term, the goal is to minimize the probability of a sequencer halt through decentralization.” This approach aims to bolster the network’s resilience and ensure a smoother user experience.While headquartered in the Seychelles, the project has its origins in China through its Chinese founders, Ye Zhang and Haichen Shen, alongside Peng, with many of its 60-strong project team based in mainland China and Hong Kong.

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.
