Tin tức từ ChainCatcher, công ty khởi nghiệp an ninh AI Attestable đã công bố chính thức thành lập và hoàn thành vòng gọi vốn hạt giống 20 triệu USD. Vòng gọi vốn này được dẫn dắt bởi Jamin Ball của Altimeter Capital và Yonatan Mandelbaum của TLV Partners, cùng với sự tham gia của các tổ chức như Halcyon Futures, Cerca Partners và nhiều nhà đầu tư khác.Người sáng lập Attestable, Yogi, cho biết, khi AI dần trở thành một phần của cơ sở hạ tầng quan trọng, an ninh quốc gia và hệ thống doanh nghiệp lớn, việc xác minh độ tin cậy của quá trình hoạt động của AI trở thành một vấn đề quan trọng mà toàn cầu đang phải đối mặt. Công ty hy vọng xây dựng một lớp xác minh chung cho các phòng thí nghiệm AI tiên tiến, cơ sở hạ tầng quan trọng và ứng dụng cấp quốc gia.Theo thông tin, Attestable sử dụng công nghệ chứng minh không kiến thức (Zero-Knowledge Proof) để chuyển giao sự tin tưởng vào hệ thống AI từ trung tâm dữ liệu sang cơ chế xác minh toán học. Công nghệ này có thể chứng minh rằng một mô hình đã được phê duyệt, trọng số mô hình, dữ liệu đầu vào và chiến lược hoạt động thực sự tạo ra đầu ra cụ thể, đồng thời không tiết lộ tham số mô hình hoặc dữ liệu riêng tư của người dùng, cũng như không cần phải chạy lại mô hình để hoàn thành việc xác minh.Attestable cho biết, công nghệ của họ hiện đã thực hiện xác minh suy diễn mô hình Meta Muse Glimmer 30B trên một GPU NVIDIA H100, đạt tốc độ 85 token mỗi giây. Tài liệu chứng minh được tạo ra có kích thước nhỏ và có tính năng an toàn chống lại lượng tử, có thể hoàn thành xác minh nhanh chóng.Về vấn đề này, Vitalik Buterin, đồng sáng lập Ethereum, đã đăng bài viết và cho rằng thành tựu này có nghĩa là hiệu suất mất mát của chứng minh không kiến thức cho các mô hình ngôn ngữ lớn đã gần đạt mức đơn số. Ông cho biết, thách thức tiếp theo là giảm thiểu thêm chi phí hiệu suất của các công nghệ như mã hóa toàn phần (FHE).

According to BIT analysis, a significant feature of Bitcoin over the past four years is that most of the price increases are concentrated in a short period of rapid growth, followed by a prolonged period of sideways consolidation. The pullback phase also shows a similar pattern, where the price usually drops quickly at first, releasing most of the downward pressure in one go, and then gradually stabilizes.This round of pullback is mainly influenced by two factors: first, the U.S. April CPI announced in May was higher than expected; second, there are concerns in the market about Strategy selling Bitcoin and the subsequent potential selling pressure. As a result, the spot Bitcoin ETF quickly shifted from net buying to significant net selling, with a cumulative net sell of about $1.5 billion this year, creating noticeable pressure on the market.Currently, Bitcoin is still under pullback pressure, with $63,445 being a key support level to watch. Whether this level can hold will affect the market's judgment on the depth of this adjustment: if the price stabilizes near this area, this pullback will still be considered a phase adjustment; if it effectively breaks below, it may enter a deeper adjustment and consolidation.

This project involves the BIS, seven central banks, and more than 40 regulated institutions, including the New York Fed, the European Central Bank, the Bank of Japan, the Bank of England, as well as JPMorgan, UBS, Deutsche Bank, and others.The prototype adopts the concept of a "unified ledger," utilizing blockchain technology to complete interbank transfers between different countries in seconds, trading in an "atomic" manner.

The cryptocurrency market was at a critical juncture on Wednesday. After failing to break through $78,000 on Tuesday, Bitcoin's price has fallen below the $76,000 "bear market boundary" defined by Tom Lee, now approaching the support level of $75,000. Ethereum also retreated after reaching $2,150 on Tuesday, falling towards the $2,000 support, and then rebounding around $2,050.

Ethereum's open interest reached a historic high of 15.57 million, but the trading volume difference is also negative, suggesting that traders are shorting contracts to bet on deeper declines after the critical technical support trendline was breached. The 30-day implied volatility index for Bitcoin rebounded from a year-to-date low, rising nearly 3% to 37.35%, indicating that the market is beginning to seek protection against potential price declines.
