Episode Description

“There's a 50% chance that by 2033, quantum computers can break Bitcoin.” Alex Pruden joins me to explain why the threat may be much closer than most Bitcoiners think, what a real quantum attack on Bitcoin would actually look like, and whether bitcoin developers are doing enough to prepare.
