Background

A long-standing open problem in mathematics is a question that has resisted solution for decades or longer, such as the Riemann hypothesis or the P versus NP problem. Theoretical computer science studies the fundamental capabilities and limits of computation, and cryptography relies on problems believed to be hard to solve. In recent years, researchers have used AI models to generate conjectures and assist in finding proofs, making AI-assisted mathematical discovery an active area of exploration.

Background

Bitcoin mining difficulty is an automatic measure of how hard it is to find a valid block hash; it adjusts after every 2,016 blocks based on the average time taken. When miners leave, the hash rate falls, and the network automatically lowers difficulty to make mining easier for those who remain. Miner revenues depend on Bitcoin price, transaction fees, and energy costs, so low revenue periods often force operators to pivot or exit. This mechanism is a key element of Bitcoin's design to maintain consistent block production.

Background

Bitcoin options are derivative contracts that give the holder the right to buy or sell bitcoin at a set price by a certain date. In the U.S., exchanges like Nasdaq and CME need regulatory approval from the SEC to list such products. The SEC's review process allows it to reconsider approvals when challenged, which is part of its oversight role.
