We Need to Talk About Quantum Computing and Bitcoin…

Quantum computing has quickly become one of the most talked-about topics in crypto. But how much of it is real? Could quantum computers eventually threaten Bitcoin? And if so, how can the industry prepare? In this episode of Trezor Sessions, Trezor CTO (Chief Technology Officer) Tomáš Sušánka answers your biggest questions about quantum computing, Bitcoin security, and post-quantum cryptography. Topics covered: • What quantum computing actually is • The “6.8 million BTC at risk” discussion • Whether today’s quantum computers are capable of attacking Bitcoin • How the industry is preparing for post-quantum security • What Trezor is doing as a company • Why this conversation matters now, not later Important context: cryptography-relevant quantum computers do not currently exist. However, researchers, security experts, and the broader crypto ecosystem are already exploring how to prepare for a future where they may become relevant.
