Bitcoin's quantum-resistant security research is making strides with several new proposals and prototypes. Jonas Nick has introduced SHRIMPS, a hash-based signature scheme supporting multi-device signatures. Avihu Levy proposed QSB, a quantum-safe transaction construction method that requires no soft fork. Meanwhile, Olaoluwa Osuntokun developed a zk-STARK-based wallet recovery prototype, allowing ownership proof without exposing mnemonic phrases. These parallel explorations aim to address potential future cryptographic risks.
