According to BTC Times, research on Bitcoin's post-quantum security is making steady progress, with researchers proposing several new solutions and prototypes. Jonas Nick introduced a hash-based signature scheme called SHRIMPS, which supports multi-device signing. Avihu Levy proposed a quantum-secure transaction construction method, QSB, that doesn’t require a soft fork. Meanwhile, Olaoluwa Osuntokun developed a zk-STARK-based wallet recovery prototype that can prove ownership without exposing the mnemonic phrase. Multiple post-quantum approaches are currently being explored in parallel to address potential future cryptographic risks. https://(wublock123.com)/news/bitcoin-post-quantum-research-multisig-recovery-prototypes-59465
