Wow, this is fascinating! I had no idea that generating random numbers for Bitcoin seed generation was such a complex process. It's interesting to learn about the different techniques used, like Pseudo Random Number Generators (PRNGs), and the potential security risks involved. Cloudflare's approach with the lava lamps is really unique and unconventional, but it makes sense to ensure genuine randomness. It's impressive that they have 96 lava lamps constantly monitored to guarantee the randomness of their backup system. I'll definitely check out the blog post for more details on how they've implemented this!
