DeFi 协议 Euler Finance 在 Sonic 上上线

专注于隐私的交易所 eXch 将于 5 月 1 日停止运营，此前有越来越多的指控称其被用于清洗 15 亿美元 Bybit 黑客攻击事件中被盗的资金。 eXch 团队在 4 月 17 日比特币论坛上发布通知称，该项目已成为“跨大西洋行动”的目标，旨在关闭该项目并可能以洗钱和恐怖主义的罪名起诉关键人物。 这家总部位于捷克的交易所以极低的“了解你的客户”要求而闻名，它强调，其创建是为了进行隐私实验，没有任何经济目的。它否认有任何协助非法活动的意图。虽然 eXch 经常被贴上“混合器”的标签，但该团队澄清说，它是一个专注于隐私的即时交易所，而不是传统的货币混合器。 该团队声称，它从“国家情报部门”的联系人那里获得情报，证实其被纳入与洗钱加密资产有关的正在进行的调查中。 该交易所此前曾否认洗钱指控，最初否认了其协助朝鲜拉撒路集团的报道。然而，后来它承认处理了“一小部分”被盗资金。 您可能还喜欢：在 Bybit 被盗 14.3 亿美元数月后，Safe 裁减了 14 名团队成员 Elliptic 和 TRM Labs 等区块链分析公司指出，eXch 是洗钱过程中的关键枢纽。2 月 21 日，Bybit 冷钱包中约 40.1 万枚以太坊 (ETH) 被盗，Lazarus 集团利用包括 eXch 在内的去中心化交易所、跨链桥和隐私工具网络，隐藏了被盗资产的来源。 eXch 在关闭公告中批评了中心化交易所所谓的“荒谬政策”，称其未能有效阻止洗钱活动。eXch 重申了其捍卫用户隐私的使命，并宣布设立 50 比特币 (BTC) 基金，用于支持比特币和以太坊生态系统中的开源隐私增强项目。 尽管eXch已关闭，但它警告称，关闭其平台并不能消除加密货币领域的非法活动。声明中写道：“认为eXch可以阻止全球所有洗钱活动，并以此为由关闭eXch，这种想法荒谬至极。” eXch 的 API 将在有限时间内继续向合作伙伴开放，与此同时，新任管理团队将决定平台的最终过渡。公告最后总结道：“隐私不是罪。” 阅读更多：得益于零售流动性，Bybit 在黑客攻击后市场份额翻了一番

美国总统唐纳德·特朗普关于加密货币的行政命令，加上美国的整体监管转变，可能会打破比特币的四年周期。 这是资产管理公司 Bitwise 首席投资官 Matt Hougan 的观点。Bitwise 高管在 1 月 29 日发布的一份报告中分享了他的观点。 霍根写道：“具体来说，我一直在想，华盛顿对加密货币的态度最近发生的变化是否足以‘打破’四年周期，并将加密货币当前的牛市延续到 2026 年及以后。” 阅读更多：Bitwise 首席执行官预测特朗普政府将推动加密货币合并 比特币的四年周期 从历史上看，比特币 (BTC) 遵循四年周期，在牛市中价格普遍上涨三年，随后回调。这种模式在 2014 年 Mt. Gox 崩盘后、2018 年美国证券交易委员会打击 ICO 期间以及 2022 年 Terra 生态系统崩溃后都曾出现过。 特朗普 11 月当选美国第 47 任总统，进一步推动了这一看涨势头。但在支持加密货币的特朗普政府领导下，华盛顿的政策转变能否打破比特币的四年周期？ 霍根相信这是可能的。 他指出，早期迹象表明，可能会出现痛苦的熊市，这是历史上过热市场过度杠杆化的模式。然而，特朗普在重返白宫的第一周签署的加密货币行政命令可能会改变这一轨迹。 霍根表示，除了其他一些积极进展外，该命令还标志着“加密货币全面主流化”。一个关键转变是潜在的监管框架，该框架可能允许银行全面进入加密货币托管市场，从而增强华尔街对数字资产的信心。 国家数字资产储备是另一个需要考虑的重要因素。综合来看，该行政令暗示，未来可能会有数万亿美元流入加密货币。 2026 年可能还不行 Bitwise CIO 表示，特朗普行政命令和其他因素预期的积极影响可能需要数年才能实现。这意味着市场不能排除 2026 年再次出现加密货币寒冬的可能性。 “我猜我们还没有完全克服四年周期。随着牛市的形成，杠杆率也会增加。过剩现象将会出现。不良行为者将会出现。在某个时候，当市场恢复正常时，可能会出现大幅回调，”霍根总结道。 你可能还喜欢：FOMC 的决定将如何影响比特币和山寨币的价格？

Aztec Network, the Ethereum layer-2 protocol focused on programmable privacy, has officially launched its public testnet. According to a May 1 press release shared with crypto.news, the launch marks a key milestone in Aztec’s eight-year journey to bring stronger data protection to web3. The testnet is now open to developers and paves the way for a fully decentralized mainnet, where no central authority will have hidden access to user data. The release follows successful internal testing phases that included over 100 sequencers. Years of research and development at Aztec led to innovations in zero-knowledge technology and programming tools that allow developers to create secure applications. These tools make it possible to keep sensitive user data private while still using Ethereum’s (ETH) infrastructure. PLONK, a proving system created by Aztec’s team to enable fast and secure zero-knowledge proofs, is at the heart of Aztec’s advancements. This technology powers the testnet’s privacy layer and served as the basis for previous products such as zk.money and Aztec Connect.

With Noir’s developer-friendly design, adding privacy to smart contracts is easier and doesn’t require a deep understanding of cryptography. According to Zac Williamson, co-founder of Aztec, privacy on blockchains doesn’t need to be “all-or-nothing,” as Aztec enables more flexible approaches. “Developers can use Aztec to build dApps with privacy features that seamlessly blend with Ethereum’s existing infrastructure, and they won’t need to struggle implementing complex cryptography.” — Zac Williamson, Co-founder of Aztec   Backed by a $100 million Series B led by a16z, Aztec is building a privacy-first Ethereum layer-2 that can scale encrypted smart contracts and support real-world use cases. Ali Yahya, General Partner at a16z Crypto, said their investment in Aztec was driven by the team’s vision of making privacy programmable and widely accessible.

UK regulators plan to ban retail investors from buying crypto assets with debt, citing financial risk and volatility. The UK is introducing sweeping rules for crypto, including a ban on buying these risky assets with debt. On Friday, May 2, the UK’s Financial Conduct Authority published a new document proposing new rules for crypto assets. The ban would include purchases made with credit cards, e-money, and any other form of debt. According to the regulators, the goal is to protect consumers in the event that these volatile assets decline in value. In addition, retail investors will be barred from engaging with certain crypto lending platforms, which the regulator deems high-risk.

For one, crypto companies would be required to establish a legal entity in the UK and fall under UK regulatory oversight. Specifically, the regulations would mandate transparent pricing and the segregation of platform assets from those of users. Moreover, the proposed regulation would ban payment for order flow, citing the potential for misuse. The practice refers to brokers directing their clients’ orders to selected market makers, potentially creating conflicts of interest. UK is ‘open for business’: FCA director David Geale, FCA executive director of payments and digital finance, stated that these regulations aim to provide investor protections. However, he dismissed claims that the country was cracking down on the crypto industry. “Crypto is an area of potential growth for the UK but it has to be done right. To do that we have to provide an appropriate level of protection,” David Geale, FCA. You might also like:A way out or a way around? Rethinking A16z’s crypto regulation Proposal He compared crypto with other high-risk assets and noted that, in many cases, crypto regulations offer even less protection. However, he emphasized that the country is welcoming toward crypto trading and innovation. “I would in some ways compare this to any other high-risk investments, which if anything often have less protections . . . We are open for business” You might also like:‘Massive year for crypto in the U.K.’: London unveils sweeping crypto rules, eyes regulatory ties with USA
