ChatGPT Helps Amateur Mathematician Solve 60-Year Erdős Problem
An amateur mathematician used ChatGPT to solve a combinatorial math problem proposed by Hungarian mathematician Erdős in the 1960s. This is another milestone in AI-assisted mathematical research, proving that large models are evolving from "assisted verification" to "substantial breakthroughs" in formal reasoning.
Hot Topic: The HN community is debating whether this is a victory for "human + AI" or a breakthrough solely by AI, as well as the issue of the strictness of mathematical proofs.

OpenAI Introduces Privacy Filter
OpenAI has released a new privacy filtering tool that allows enterprise users to automatically filter sensitive information when calling the API. This is another step for OpenAI in compliance within the enterprise market, following the data retention policy.
Qwen3.6-27B Runs 100 TPS on a Single RTX 5090
Using vllm 0.19 and INT4 quantization, Qwen3.6-27B achieved 100 tokens/second at a 256k context length. Consumer-grade GPUs are approaching the performance of last year's enterprise-level inference cards, further lowering the cost threshold for local deployment.
> Hot Comment: Last year we were discussing "cloud vs local", this year it has turned into "which consumer card offers better value". The speed at which AI computing power is becoming more accessible is faster than everyone expected.

CFTC Sues New York State to Regulate Coinbase and Gemini
The U.S. Commodity Futures Trading Commission has filed a lawsuit against the New York State Department of Financial Services, claiming its regulatory intervention on Coinbase and Gemini intrudes on federal jurisdiction. This marks the first direct conflict between U.S. federal and state regulators in the crypto space, potentially reshaping the American crypto regulatory landscape.
KelpDAO Vulnerability Leads to DeFi Community Establishing Recovery Fund
After the KelpDAO vulnerability caused rsETH to depeg, protocols such as Aave, EtherFi, Ethena, and Lido jointly established a recovery fund with KelpDAO contributing 2000 ETH. The final plan has been determined, awaiting DAO votes and technical execution, affecting 71,700+ users.
Hot Topic: The community is discussing whether this represents the "DeFi mutual aid spirit" or "large protocols having to save themselves to prevent systemic risk".

Tether Freezes $344 Million Iranian Central Bank Wallet
The U.S. Treasury's OFAC has blacklisted two cryptocurrency wallets directly linked to the Iranian Central Bank, and Tether cooperated in freezing $344 million. This is the largest single amount of sanctions enforcement by a stablecoin issuer, once again exposing the "switch" risk of centralized stablecoins.
Brazil Bans Kalshi and Polymarket
Brazilian regulators have banned prediction market platforms like Kalshi and Polymarket under the pretext of "protecting investors from unlicensed gambling risks". Following China and India, yet another emerging market says no to decentralized prediction markets.
Litecoin Rewrites 3-Hour History to Undo Privacy Layer Vulnerability
The Litecoin network experienced a significant vulnerability in its privacy layer that caused double-spending, and miners coordinated to rework the chain and rollback 3 hours of transaction history. This is yet another collision between the promise of "immutability" and the reality of security.
> Hot Comment: Tether freezing $344 million only requires a backend operation, while Litecoin rolling back 3 hours requires coordination from all network miners. Sometimes, "decentralization" turns out to be more fragile.

A-shares Have Second Longest "Huddling" Since 2007
CITIC Securities' research report points out that the current institutional huddling duration in A-shares is the second longest since 2007, and the next asset allocation direction is advised to be "neither hot nor conflicting". Core asset valuations are at historical highs, and signals for style switching are gradually strengthening.
Today's Underlying Trends
As ChatGPT helps an amateur mathematician crack the Erdős problem, Trump has fired the entire National Science Board; Tether's freezing of $344 million Iranian wallets demonstrates the real existence of stablecoin "switches", while Litecoin had to rely on full network coordination to rollback 3 hours to fix its vulnerability. The tech world of 2026 is staging two parallel narratives: AI is empowering individuals like never before, but macro power structures (whether government or centralized protocols) are becoming more explicit and direct. "Decentralization" is not a technological issue; it is a political economic issue.
