sign

Sign usually refers to digital signature technology in the fields of blockchain and cryptocurrency. A digital signature is a cryptographic technique used to verify the authenticity and integrity of digital information. It encrypts and decrypts data using public and private keys, ensuring that only users holding the private key can generate a valid signature, thereby providing authentication and data integrity assurance. Digital signatures play a key role in smart contracts, transaction verification, and identity authentication.

first_img OpenAI announced significant progress on the Millennium Prize Problems

OpenAI stated to The New York Times that since announcing progress on the Navier-Stokes equations on September 8, it has made "substantial progress" on one of the Millennium Prize Problems, but did not disclose which specific problem it is or provide a timeline for disclosure. The Millennium Prize Problems are seven mathematical problems established by the Clay Mathematics Institute since 2000, each with a reward of one million dollars.Speculation suggests that the problem may be the Hodge Conjecture, a 76-year-old problem regarding how to calculate the number of "holes" in complex geometric shapes. OpenAI has not confirmed this speculation and has not responded to rumors that its underlying model is a version of Aeon specifically designed for long-duration tasks. Previously, on September 8, OpenAI announced that its unreleased internal model generated a proof verified by Lean, indicating that the Navier-Stokes equations could "blow up" to physically impossible infinite speeds, involving about 10,000 coordinated AI agents and taking approximately 88 hours.However, this statement has sparked controversy. New York University mathematician Tristan Buckmaster stated that he and Anthropic researcher Levent Alpöge had been working on the related proof for nearly a year prior and completed it on August 22, while OpenAI's Sébastien Bubeck published his findings first upon learning of it. OpenAI stated that it is not pursuing the one million dollar prize, but rather using these problems as a public benchmark to measure the speed of model progress. The review of the Navier-Stokes proof by the Clay Mathematics Institute is still ongoing, and verification of past Millennium Prize Problems typically takes several years.

first_img The head of Grayscale Research reiterated that Bitcoin at $58,000 is the bottom, signaling a green light to clients

According to The Block, Grayscale's research director Zach Pandl stated that the approximately $58,000 low reached around June 30 remains his assessment of the bottom of the current bear market phase, and Grayscale is currently advising clients to allocate Bitcoin.Pandl mentioned in an interview with The Block during the Avalanche summit in New York that they have maintained the view that $58,000 is the bottom of this bear market phase for the past few months. This assessment echoes the comments made by Coinbase CEO Brian Armstrong, who stated on September 10 that Bitcoin has bottomed out in the current cycle and expects a sustained upward trend for the next two years.Pandl stated that Grayscale uses a three-part framework to assess whether clients should allocate Bitcoin, including long-term structural trends, market cycle phases, and macro context. He believes that all three conditions are currently met, thus giving clients the "green light" to allocate Bitcoin. As of Thursday morning, Bitcoin was above $76,000, up 0.8% in 24 hours, but still down about 39% from its historical high of approximately $126,000.Pandl also compared Bitcoin with Zcash, noting that Grayscale has offered investment products for Zcash for about nine years. He believes that Zcash occupies an "underutilized and unexplored design space," rather than directly competing with Bitcoin, and pointed out that as artificial intelligence becomes more powerful, privacy issues are receiving more attention, with Zcash providing investors a way to express their views on personal and financial privacy.

Phishing websites use meme coin display pages to attract traffic, resulting in significant losses for multiple traders

Recently, the meme coin market has been booming, and on-chain trading has become increasingly active. However, with the warming market, meme coin display pages have frequently shown highly disguised phishing links, and the "novel" attack methods have caused several seasoned traders to fall victim. Crypto KOLs @insidecalls and @cladzsol recently revealed that while scanning chains, they clicked on the meme coin homepage, which resulted in a "cloudfare verification" prompt. After completing the verification as instructed, the victim's on-chain funds were stolen. Among them, @cladzsol lost approximately $600,000 in assets.According to market news, on several recently popular meme coin display pages, the homepage redirects to a "cloudfare verification" page, which is actually a phishing link. If users follow the prompts, their computer systems will download and execute malicious scripts, leading to asset loss. This phenomenon is so rampant that it may be related to the delayed review processes of mainstream trading aggregation platforms like DexScreener. Currently, the display logic of relevant platforms is to directly reference the "official website" or social media links filled in the token metadata. These fields can be updated by token creators or those who later claim "community takeover." Hackers are exploiting this review loophole to transform meme coin display pages into new "fishing grounds" for phishing attacks. Users may inevitably click on unfamiliar links during the chain scanning process; if a "cloudfare verification" or other highly suspicious page appears, they should close it immediately to avoid interaction and protect their asset security.
