Hash-based signatures for Bitcoin's post-quantum future? with Jonas Nick | SLP713

In this conversation, Stephan Livera and Jonas Nick discuss the implications of quantum computing on Bitcoin's security, focusing on the risks posed to cryptographic signatures. They explore the current vulnerabilities in Bitcoin, the potential for quantum attacks, and the need for post-quantum cryptographic solutions. The discussion covers various signature schemes, including hash-based signatures, their trade-offs, and the challenges of transitioning to a quantum-resistant Bitcoin. They also touch on the implications for hardware wallets, multi-signature schemes, and the potential need for block size increases to accommodate new signature sizes.
