前工程师警告称，如果没有明确的领导，以太坊的未来将面临风险

Coinbase 正在敦促美国银行业监管机构允许银行提供加密货币服务，包括交易和托管。 据彭博社报道，该加密货币交易所认为，现行法规设置了不必要的障碍，阻碍银行全面进入数字资产市场。 Coinbase 在致货币监理署、美联储和联邦存款保险公司的一封信中呼吁进行改革，使银行更容易与加密货币公司合作。 你可能还喜欢：比特币能否在即将到来的金融崩溃中幸存下来？| 观点 美国银行需要额外批准才能参与加密货币业务 具体来说，Coinbase 要求 OCC 撤销一项政策，该政策称该政策对希望从事加密相关活动的银行施加了额外的审批。它还敦促美联储和联邦存款保险公司确认，受其监管的银行既可以提供加密服务，也可以外包加密服务。 由于监管不确定性，银行一直不愿进入加密货币领域。据报道，2022 年至 2023 年期间，联邦存款保险公司 (FDIC) 要求一些金融机构暂停或限制其加密货币活动。这导致银行不再提供数字资产服务，尽管机构和散户投资者有需求。 Coinbase 的举措正值唐纳德·特朗普总统执政期间监管环境发生变化之际。特朗普任命了对加密货币持更开放态度的监管机构，并最近废除了美国证券交易委员会的一项规定，该规定使银行提供加密货币托管服务的成本变得高昂。 Coinbase 发出这封信的时间值得注意，因为参议院银行委员会正在准备就“去银行化”举行听证会——即切断对某些行业（包括加密货币）的金融服务。Coinbase 长期以来一直认为，严格的银行政策使加密货币公司难以获得传统金融服务。 Coinbase 的请求得到了三家大型律师事务所的支持，它们认为现行法律已经允许银行与加密货币公司合作。美国货币监理署和联邦存款保险公司拒绝置评，美联储尚未回应。 你可能还喜欢：2 月份 Solana 和莱特币可能会飙升；以下是分析师的看法

Tornado Cash developer Roman Storm faces a trial in the United States in July, and a federal judge has declined to order the U.S. Department of Justice to review its records related to the case. Judge Katherine Polk Failla, in a Friday ruling, declined to order the DOJ to review materials it holds that might be helpful to Tornado Cash (TORN) developer Roman Storm’s legal team. The judge’s ruling comes as Storm and his defense team prepare for the developer’s trial scheduled for July 2025, CoinDesk reported. “I’m not going to require a further review based on the representations made that there’s no additional material of this type, and based on my views that I don’t believe the material was exculpatory,” the judge noted. The judge’s decision is key, as an order finding that prosecutors failed to share all relevant information in their possession with Storm’s legal team could have impacted the defense’s case during trial. The law requires that prosecutors share with the defendant all information they have that could aid the accused person’s defense. Storm is set to stand trial after the DOJ confirmed earlier this month that the government will proceed with the prosecution of the Ethereum mixer co-founder.

Instead, prosecutors will now go after what they termed “bad actors” within the industry who exploit such solutions to aid illicit activities like money laundering. The DOJ’s crackdown would not be focused on the platforms, but bad players. The DOJ initially filed charges against Roman Storm and Roman Semenov, another Tornado Cash founder, in August 2023. The charges included operating the mixing service and laundering more than $1 billion. In February this year, a Dutch court released Alexey Pertsev, a Tornado Cash developer arrested in August 2022 in Amsterdam. Read more:Monero breaks out as privacy demand surges post-Tornado Cash

随着以太坊探索转向 Poseidon 哈希函数以增强其零知识证明能力的可能性，Vitalik Buterin 呼吁研究人员加入 Poseidon 加密分析计划。 以太坊 (ETH) 联合创始人 Vitalik Buterin 在 X 上的最新帖子中鼓励研究人员加入 Poseidon 加密分析计划。Vitalik 正在考虑切换到 Poseidon 哈希函数，以改进其与 zk-provers（用于私下验证交易的工具）的配合使用。为了帮助做出这一决定，以太坊希望获得有关 Poseidon 安全性的更多信息，并且他们已将申请资助计划的截止日期延长至 3 月 15 日。 强烈鼓励研究人员参与 Poseidon 密码分析计划。我们正在认真考虑将以太坊迁移到 Poseidon 哈希以优化 zk-prover 友好性，因此拥有更多有关其安全属性的信息非常有价值。https://t.co/AhbV8abD4z— vitalik.eth (@VitalikButerin) 2025 年 2 月 26 日 2022年11月，一项名为以太坊改进提案（EIP）5988的提案被提出，建议在以太坊虚拟机中添加预编译合约以实现Poseidon哈希函数，旨在增强EVM与零知识汇总之间的互操作性。 你可能还喜欢：什么是以太坊虚拟机 (EVM)？深入探究 自该提案提出以来，EIP 5988 似乎还没有任何官方实施或重大更新，但看起来以太坊仍在认真考虑实施 Poseidon。 Poseidon 哈希函数于 2019 年推出，与 SHA-256 和 Keccak 等成熟的哈希函数相比相对较新，后者已经存在了几十年，并经过了广泛的测试。然而，SHA-256 或 Keccakt 并非专门为零知识证明而设计。相比之下，Poseidon 专门为零知识证明而设计。虽然它没有像 SHA-256 和 Keccak 那样经过广泛的测试，但 Poseidon 已经在以太坊网络和其他区块链项目的第 2 层系统中投入生产。 以太坊对 Poseidon 哈希函数的探索只是其增强网络性能的广泛努力的一小部分。最值得注意的是，期待已久的 Pectra 升级将于 4 月 8 日正式启动，旨在增强以太坊的可扩展性、改善账户抽象、提高第 2 层效率并增加验证者奖励。此次升级是在最近的 Dencun 硬分叉之后进行的——该硬分叉于 2024 年 3 月推出，大幅削减了第 2 层网络的交易费用。 你可能还喜欢：以太坊 Pectra 升级计划于 4 月 8 日进行主网升级

SBI VC Trade has become the first firm in Japan to receive regulatory approval to handle stablecoins. The exchange plans to start processing USDC transactions on March 12. According to a report by CoinDesk Japan, SBI Group’s crypto trading firm has become the first Japanese firm to gain approval for an “electronic payment instrument business operator” license. The firm is registered at the Kanto Regional Financial Bureau with registration number No. 00001. After receiving the license, SBI VC Trade plans to start facilitating transactions for Japanese customers through the Circle-issued stablecoin, USD Coin (USDC), on March 12. However, the firm noted that the stablecoin service will remain in the beta phase and distribution will be restricted to only a few customers within the group. Once the stablecoin service becomes available to the public, SBI VC Trade will be able to offer services that will enable individual and corporate customers to buy and sell as well as deposit and withdraw USDC. Because the stablecoin is pegged to the U.S. dollar, SBI VC Trade will need to stock up on U.S. dollars, securing an amount that is equal to or greater than the amount of USDC deposited by customers. 你可能还喜欢：Circle 首席执行官预测稳定币将在香港贸易中发挥重要作用 SBI VC Trade 首席执行官近藤智彦表示，SBI 集团旗下新生信托银行将负责该公司的信托安全。他表示，到测试版发布时，用户将能够在该公司的交易平台上看到“USDC”。 该稳定币将可与现货交易对进行交易，包括 BTC/USDC 和 ETH/USDC 对。预计该交易平台还将包括与 USDC 的杠杆交易。 他在一份翻译声明中表示：“我们将首先检查业务流程。我们希望尽快正式启动这项计划。” At press time, SBI VC Trade is the only Japanese firm that holds all three operating licenses: a cryptocurrency exchange business license, the financial instruments business type 1 license, and theelectronic payment instruments trading business license. Last February, the Japanese Financial Services Agency approved a report which included a reform that would allow for stablecoins to be backed by short-term government bonds and fixed-term deposits in addition to demand deposits. In addition, the proposal also recommended an upper limit of 50% on the bonds and deposits that can be used as collateral for stabelcoins.

Despite the news that Binance will delist the token on May 2, Alpaca Finance shocked the cryptocurrency market with a 1,100% price increase in the last week. Binance announced on Apr. 24 that it would remove ALPACA and three other tokens from its platform following a routine evaluation. The exchange cited factors such as low trading volume and developer inactivity. ALPACA spot trading pairs will be disabled on May 2, while deposits and withdrawals were phased out in the days after the announcement. Normally, tokens drop in value after delisting news, but ALPACA did the opposite. After briefly declining in response to the news, ALPACA surged by as much as 2,300% in just a few days, jumping from $0.029 to a peak of $1.47, a 60x increase on some trading pairs. ALPACA is now trading at $0.53, down 40% in 24 hours but still up 1,100% over the past week, as per CoinGecko data. The rally appears to have been driven by a short squeeze. After the delisting news, many traders opened short positions expecting the price to collapse. However, they were forced to buy back the token to cover losses when ALPACA unexpectedly surged, which caused the price to rise even further.  You might also like:Bitget to take legal action against eight accounts for $20M VOXEL token manipulation The squeeze was further tightened when Binance modified its funding rates. The funding cap was increased from ±2% to ±4%, and settlement intervals were reduced from four hours to one hour, which resulted in higher costs for short sellers. This made holding bearish positions expensive and risky. Meanwhile, ALPACA’s supply tightened. A supply shock was caused by the team’s suspension of new token issuance and the burning of about 35 million tokens, or 18.6% of the maximum supply. Some on-chain observers suspect market manipulation. Positions totaling more than $50 million, including $43 million from short sellers, were liquidated. It’s possible that coordinated whale activity contributed to price increases which caught leveraged traders off guard. The situation was likened to the Gamestop short squeeze of 2021, in which institutional short sellers were outbid by retail traders. However, there are still concerns about how long the ALPACA pump can last and what will happen after Binance’s final delisting.
