Show Notes

Brandon Black is a Bitcoin software engineer. In this episode we discuss why quantum computing is unlikely to threaten Bitcoin in the foreseeable future, how exaggerated claims around qubit scaling and Shor’s algorithm distort the real risk, what concrete evidence would actually force Bitcoin to act, and how questions around soft forks, post quantum cryptography, property rights, and confiscation should be framed if progress ever becomes real.
