A recent a16z crypto research paper challenges the notion that quantum computers will abruptly end Bitcoin, suggesting instead that the real danger lies in prolonged migrations rather than a sudden collapse. Justin Thaler, a Georgetown professor and a16z research partner, argues that timelines for a viable quantum computer are often exaggerated, diverting attention from immediate risks like implementation errors. He defines a 'cryptographically relevant quantum computer' (CRQC) as one capable of breaking RSA-2048 within a month, which he deems unlikely in the 2020s. Thaler emphasizes that while post-quantum encryption is urgent for long-term data, Bitcoin's signature vulnerabilities differ, as they do not protect hidden data. Critics like Nic Carter and Alex Pruden counter Thaler's claims, asserting that quantum threats are more imminent and that blockchains are particularly attractive targets due to their public keys linked to value. They argue that the industry must act now to avoid panic later, as the migration to post-quantum solutions will be complex and time-consuming.
