Caught up with some friends who work in cyber security. They're not Bitcoiners, but they have a good understanding of how the protocol functions. We had a long discussion about security, and how Bitcoin could be attacked from a purely technical perspective. One issue that took up a lot of discussion was the DNS seeds and hard-coded seed nodes, and whether those represented a vulnerability. We all went back and forth. I asked AI, and I thought the answer was quite reasonable.
