ChatGPT Helps an Amateur Mathematician Solve a 60-Year Erdős Problem

An amateur mathematician used ChatGPT to solve a combinatorics challenge proposed by Hungarian mathematician Erdős in the 1960s. This is another milestone in AI-assisted mathematical research, showing that the capabilities of large models in formal reasoning are evolving from “assistive verification” to “substantive breakthroughs.”

Hot Discussion: The HN community is debating whether this is a “human + AI” victory or a pure AI breakthrough, as well as the rigor of mathematical proofs.

OpenAI Launches a Privacy Filter

OpenAI released a new privacy filtering tool that allows enterprise users to automatically filter sensitive information when calling the API. This is another step in OpenAI’s push to bring enterprise-market compliance in line after its data retention policy.

Qwen3.6-27B Hits 100 tps on a Single RTX 5090

Using vllm 0.19 and INT4 quantization, Qwen3.6-27B reaches 100 tokens per second with a context length of 256k. Mainstream consumer GPUs are closing the performance gap with last year’s enterprise inference accelerators, and the cost threshold for local deployment has dropped another notch.

Reddit Discussion

Hot Take: Last year, people were still debating “cloud vs. on-prem,” and this year it’s already “which consumer card offers better cost-effectiveness.” The pace at which AI compute is trickling down is faster than everyone expected.

CFTC Sues New York State Regulators Coinbase and Gemini

The U.S. Commodity Futures Trading Commission filed a lawsuit against the New York State Department of Financial Services, claiming that its regulatory intervention into Coinbase and Gemini infringed on federal authority. This is the first direct clash between U.S. federal and state regulators in the crypto space, and could reshape the overall landscape of U.S. crypto regulation.

DeFi Community Sets Up a Recovery Fund After the KelpDAO Vulnerability

After the rsETH de-pegging caused by a KelpDAO vulnerability, protocols including Aave, EtherFi, Ethena, and Lido jointly established a recovery fund, with KelpDAO contributing 2000 ETH. The final plan has been set—waiting for DAO voting and technical execution, with 71700+ users affected.

Hot Discussion: The community is debating whether this reflects a “DeFi spirit of mutual aid” or whether big protocols have no choice but to rescue themselves to prevent systemic risk.

Tether Freezes $344 Million in Iranian Central Bank Wallets

The U.S. Treasury’s OFAC has blacklisted two crypto wallets directly linked to the Iranian central bank, and Tether cooperated to freeze $344 million. This is the largest single amount of sanctions enforcement carried out by a stablecoin issuer, once again exposing the “switch” risk of centralized stablecoins.

Brazil Bans Kalshi and Polymarket

Brazilian regulators banned prediction market platforms such as Kalshi and Polymarket, citing “protecting investors from the risks of unlicensed gambling.” After China and India, another emerging market has said no to decentralized prediction markets.

Litecoin Rewrites 3 Hours of History by Rolling Back a Privacy-Layer Vulnerability

For the first time, the Litecoin network encountered a major vulnerability in the privacy layer that led to double-spending. Miners coordinated a chain reorganization and rolled back 3 hours of transaction records. This is yet another collision between the “immutable” promise and real-world security.

The Block

Hot Take: Freezing $344 million by Tether only requires a backend operation, but rolling back 3 hours of Litecoin transactions requires miners across the entire network to coordinate. Sometimes, “decentralization” is actually more fragile.

Trump Fires the Entire National Science Board

The Trump administration dismissed all members of the U.S. National Science Board (NSB). The NSB is responsible for providing policy recommendations to the National Science Foundation, and this move has raised concerns in academia about funding for and independence in basic research.

The Verge

Hot Take: While Silicon Valley is snatching up H100s, the White House is clearing out the science advisory team in front of everyone’s eyes. The AI boom and the winter of basic research are happening simultaneously in the U.S. in 2026.

A-Share “Huddle” Becomes the Second-Longest Since 2007

A research report from CITIC Securities points out that the current duration of institutional “huddling” in A-shares is the second-longest since 2007. For the next allocation direction, it suggests “neither popular nor confrontational.” Core asset valuations are already at historical highs, and signals for a style rotation are strengthening.

Today’s Hidden Thread

While ChatGPT helps amateur mathematicians crack Erdős problems, Trump fired the entire National Science Board; Tether froze $344 million in Iranian wallets, proving the “switch” of stablecoins is real; and Litecoin relied on full-network coordination to roll back 3 hours to fix a vulnerability. In 2026, two parallel narratives are unfolding in the tech world: AI is giving individuals unprecedented capabilities, but the macro power structure(—whether it’s governments or centralized protocols)—is becoming more explicit and direct. “Decentralization” is not a technical issue—it’s a political economy issue.
