马斯克发力 XChat,“比特币风格”的加密架构到底是个啥?

marsbitPublished on 2025-06-01Last updated on 2025-06-02

6月1日,马斯克开始发力,宣布X平台推出全新消息系统XChat,主打端到端加密、消失消息、任意文件传输和跨平台音视频通话。

也就是说,X 不仅能够发推看推了,后续或许会逐渐具备类似于 Telegram 或微信的即时聊天功能。

目前该功能还在测试阶段,并不是所有用户都能体验到。

不过更吸引眼球的是,马斯克宣称XChat采用了“比特币风格的加密”,并用Rust语言开发,号称“全新架构”。

数字签名

比特币过于经典,经典到以至于很多人对它的名字如雷贯耳,将其当做一种领头羊资产在对待,但对它到底用了怎样的技术并不是很清楚。

马斯克所说的比特币风格的加密架构,到底是个啥?笔者又翻了下比特币白皮书,站在一个老韭菜的角度来解读一下。


XChat 测试版功能抢先看

据某些推友反馈,自己的 X 账号当前已经被推送了 Xchat,并标记为"Beta”测试版,最核心的功能是私信会在你所有的设备上进行端到端加密,任何人都无法读取你的私信,X也不例外。

数字签名

那么我们可以结合马斯克的原贴以及网友反馈,拆解一下这个功能。

  • 端到端加密:消息、通话内容只有通信双方能看到,第三方(包括X平台)无法窥探。
  • 阅后即焚:可以设置消息在一定时间后自动删除,比如10分钟后,保护隐私更彻底。
  • 任意文件传输:支持发送任何类型的文件,包括照片、视频、文档等,不再受限于格式或大小。
  • 跨平台音视频通话:无需手机号即可拨打,支持手机、电脑等多设备,通话内容同样加密。

你别说,这还有点像 Telegram 。


这关比特币什么事?

提到“比特币风格加密”,很多人的第一反应可能是:比特币不是用来转账的吗,跟加密聊天有啥关系?

别急,我们先来回顾一下比特币的加密技术,再看看XChat可能怎么借鉴。

数字签名

其实十多年前的比特币白皮书标题已经说的很清楚了,“点对点的现金支付系统”,这里的点对点也即经常听到的P2P。

BTC---想要实现点对点(我和你)转账,不需要中间人来管;

Xchat---想要实现点对点(我和你)聊天,不需要中间人来管。

这是同源技术的不同实现方向。

要点对点,比特币是怎么做的呢?

把区块链的账本技术先放在一边,比特币要实现点对点转账,使用的加密技术,简单说就是“锁”和“签名”。

  • “锁”:椭圆曲线加密(ECC): 比特币用了一种叫椭圆曲线加密(ECC)的东西,简单说,它就像一把超级安全的锁。每个人都有两把钥匙:一把是公钥(公开的,相当于锁),一把是私钥(只有你知道,相当于钥匙)。比如,你要给朋友转比特币,你的钱包会用朋友的公钥“锁”住这笔交易,只有朋友用自己的私钥才能“开锁”,拿到钱。整个过程没人能偷看或篡改,连比特币网络都看不到交易细节。
  • “签名”:数字签名(ECDSA) 除了“锁”,比特币还用数字签名来证明“你是你”。当你转账时,你的钱包会用私钥生成一个签名,证明这笔交易确实是你发的。别人可以用你的公钥验证这个签名,但无法伪造。
  • “防篡改”:哈希算法(SHA-256) 比特币还用了一种叫SHA-256的哈希算法,把交易信息变成一串固定长度的“指纹”。如果交易被改动,哪怕只改一个字母,指纹也会完全不同,网络马上就能发现。

注意,这些加密算法和签名算法,并不是比特币发明的,而是将它们放在一起综合使用。

数字签名

 

因此,结合XChat的功能,我们可以推测它可能这样用比特币的技术,也就是马斯克口中的“比特币风格加密”:

  • 端到端加密:消息的“保险箱” XChat的端到端加密可能用了ECC的变种(比如ECDH协议)。当你发消息给朋友,你的手机会用朋友的公钥加密消息,只有朋友的私钥能解密。 举个例子:你发“我今晚7点到”,消息会变成一串乱码,只有朋友的设备能解开,X平台或其他人都看不到。音视频通话也可能用类似方法,保护通话内容不被窃听。
  • 数字签名:证明消息是你发的 XChat可能用类似ECDSA的数字签名技术,确保消息来源可信。比如你发了一份合同文件,XChat会用你的私钥签名,朋友收到后可以用你的公钥验证,确认文件是你发的,没被篡改。
  • 阅后即焚:加密+定时销毁 消失消息功能可能结合加密和定时销毁机制。消息加密后,只有接收方能看,服务器会在指定时间(比如10分钟)后自动删除,即使设备被黑客攻破,也找不到历史消息。
  • 文件传输:防篡改的“指纹” 传输文件时,XChat可能用SHA-256生成文件的哈希值(指纹)。朋友收到文件后,系统会自动验证指纹,确保文件没被中途篡改。

至于用什么开发语言,RUST还是啥,笔者并非技术出身在此不做过多解读。


不止于聊天

XChat的推出,不只是一个聊天工具那么简单。

马斯克一直想把X打造成“everything app”(超级应用),类似我们常用的微信。

数字签名

从他的一些动作上是可以看出端倪的,比如先收购推特,再借鉴微信的诸多功能,集成 Grok AI 等等。

而随着美国稳定币法案的逐渐通过以及加密友好的大环境形成,后面我们也有理由期待支付相关的功能出现,比如 XPay。

微信在中国的成功,靠的是基于社交关系和强大的粘性,把聊天、支付、打车、购物等功能融为一体。XChat如果能整合支付(XPay)、AI助手(Grok 3)、社交(X平台的社区功能),再加上强大的隐私保护,完全有可能成为西方的“超级微信”。

最后,再来看看“比特币风格加密”这个说法真的那么独特吗?其实未必。

椭圆曲线加密(ECC)、数字签名(ECDSA)、哈希算法(SHA-256)这些技术,早就不是比特币的专属。

很多安全应用都用类似技术,比如WhatsApp、Signal的端到端加密,也依赖ECC和哈希算法;苹果的iMessage甚至在2010年代就采用了ECC。比特币的加密技术虽然可靠,但更像是“行业标配”,并没有太多独创性。

马斯克选择“比特币风格”这个表述,更可能是出于营销考量。比特币作为加密货币的“代名词”,自带流量和信任光环。

不过亲加密的表述越多,我们当然越开心。

在注意力代币化的大环境里, X和马斯克后续的更多功能和玩法,也同样值得期待。

2028: The Arrival of Recursive Self-Improvement (RSI)

**AI Recursive Self-Improvement (RSI): The Countdown to 2028 Begins** AI is no longer just a trained tool but is starting to rewrite its own evolutionary pace. According to Anthropic co-founder Jack Clark, there is a 60% probability that by the end of 2028, Recursive Self-Improvement (RSI) will become a reality. This means AI could autonomously design and build a more capable next-generation version of itself without any human researcher involvement—Claude 10 creating Claude 11, for instance. Supporting this timeline, Google DeepMind's CEO Demis Hassabis confirms that all leading AI labs are intensely focused on RSI, making it an industry-wide priority. He expresses profound concern, stating this potential is what keeps him awake at night. Concrete data underscores this acceleration: - METR evaluations show current top models like Claude are solving tasks up to the 16-hour limit of existing test frameworks. - In Epoch AI's challenging MirrorCode benchmark, Claude Opus 4.7 recreated complex software in hours for a fraction of the human cost. In one extreme test, AI autonomously coded for 19 days straight. - Anthropic reports over 80% of its codebase is now written by Claude, and researcher productivity has increased up to 8-fold since 2024. - OpenAI's policy blueprint highlights RSI as a major upcoming governance challenge. CEO Sam Altman reportedly hinted RSI might arrive within six months, potentially delaying OpenAI's massive IPO. The implication is an impending "intelligence explosion," where AI-driven progress outpaces human control. The central question is no longer if it will happen, but whether humanity is ready.

World Models, Metaverse, Digital Twins, Physical AI: Are They the Same Thing?

Title: World Models, the Metaverse, Digital Twins, Physical AI: Are They the Same Thing? The article clarifies that concepts like the metaverse, Web3, simulation platforms, digital twins, and Physical AI are not the same thing but are all part of the broader trend of blurring the lines between the digital and physical worlds. It positions "world models" as the foundational "cognitive layer" or "operating system" that enables AI to understand and simulate the world. Key distinctions are made: - The **Metaverse** is a destination for immersive social and economic experiences. World models could act as its "engine," generating interactive 3D content efficiently. - **Web3** focuses on decentralized ownership and economics (rules layer), operating on a different technical level than world models. - **Simulation Data Platforms** (e.g., for autonomous vehicles) are a 1.0 version, relying on manual design. World models represent a 2.0 version, using AI to generate realistic, varied scenarios autonomously. - **Digital Twins** create high-fidelity, real-time mirrors of physical systems (e.g., a factory). World models go a step further by enabling predictive simulation of future states. - **Physical AI** (robots, AVs) refers to AI that acts in the physical world. World models are a core component, providing the understanding and prediction needed for planning. A proposed hierarchy places world models at the cognitive layer, supported by infrastructure (compute, data) and supporting application tools (simulation, digital twins), action systems (Physical AI), user experiences (metaverse), and rules (Web3). In conclusion, while distinct, many of these previously hyped concepts may ultimately rely on advances in world model technology to fulfill their promises, as world models provide the essential cognitive foundation for simulating and interacting with complex environments.

"Shocking" CPO: How Does the Glass Bridge Actually Work? Detailed Explanation from Corning

Chinese CPO stocks plunged over 6% following Corning's announcement of its Glass Bridge platform at a Seoul tech conference. The new technology utilizes wafer-level glass ion-exchange waveguides for passive alignment between fibers and photonic chips, potentially simplifying traditional CPO architectures that rely on complex Fiber Array Units and active alignment equipment. This raised market concerns about reduced long-term demand for mid-stream CPO components. Corning's official documentation details Glass Bridge as a platform for fiber-to-PIC connectivity in NPO, CPO, and high-density modules. Its key features include wafer-level manufacturing for consistent, cost-effective production; a standardized, removable MT ferrule interface for ecosystem integration; and a separable high-density connector design supporting over 24 channels for assembly flexibility. Corning positions the technology as complementary to FAUs, addressing limitations in ultra-high-fiber-count scenarios. The market reaction reflects a broader reassessment of the AI optical interconnect value chain. Funds shifted from CPO and PCB manufacturing stocks towards glass substrate concept stocks like Kaisheng Technology and Dyer Laser. Analysts note glass substrates are seen as a next-gen advanced packaging material, offering a potential path for domestic industry differentiation amid AI-driven demand for high-performance, large-scale packaging, marking a structural migration in value towards upstream specialty materials.
