- 1Bitcoin Taproot debate: exposed keys and quantum risk▼Taproot: not your public key hashes, totalitarian state CRQCs' coins # Bitcoin
A Bitcoin discussion is arguing that Taproot's design, which places full public keys on-chain instead of hashes, could leave those coins exposed to cryptographically relevant quantum computers, potentially including machines held by authoritarian states able to raid such funds. Critics counter that hash-based outputs offer some quantum protection, and the exchange is feeding wider debate about Taproot's security trade-offs and quantum-resistance of Bitcoin.
- 2HashSmash Challenge Pits Crypto Hashes Against AI Attacks●HashSmash Challenge Tests Crypto Hashes Against AI Attacks
The HashSmash Challenge is testing whether cryptographic hashes can withstand AI-driven attacks, drawing attention from security researchers and enthusiasts. Participants are exploring how machine learning tools fare against established hashing methods, sparking debate about whether current cryptographic standards remain robust as AI capabilities advance.

An online mathematics project is assigning a SHA-256 hash to each of 5,000 integer sequences decomposed into a unique weight × level + jump form, verifying the decomposition at every deployment. Primes are among the sequences given cryptographic fingerprints, with Claude assisting in generating and checking the hashes, a hybrid of number theory and software integrity practice.

Security firm Trail of Bits says combining multiple values into a single hash is easy to get wrong, and those mistakes can enable forgeries. It notes TupleHash addresses the problem but only works with Keccak, while outside SHA-3 developers often roll their own, insecure multihashing. The firm has built SequenceHash, a length-suffixed construction that works with any hash function.
