Jameson Lopp took part in a podcast where he talked more about the threat of quantum computing and this BIP proposal with the host Pete Rizzo. It's a 45-min podcast and you can watch it below if you are intereted:
https://x.com/SupplyShockBW/status/1948749357316276516Jameson talks about how the network can't afford to wait until quantum computers become an unpredictable threat and that the Bitcoin community needs to plan ahead. He talks about quantum computers becoming a global phenomena in the future. Even if the US managed to regulate the development somehow, there is nothing they can do to stop Russia or China, for example, to do the same. Jameson doesn't believe QCs are anywhere near to breaking Bitcoin's cryptography at the moment but it's impossible to predict future advancements.
On the current quantum-resistant algorithms, Lopp doesn't believe any is good enough for Bitcoin. He even said "
they suck" if I remember it correctly. They take up too much space. The signatures and keys are longer and they are slower to verify. He clarified that the idea of the BIP is not to choose a post-quantum algorithm, but how to get the community to migrate to a new system asap after one is chosen.
He mentioned satoshi's coins as an example. He said that freezing his coins violates the principles of Bitcoin but if they didn't migrate, quantum computers might steal them eventually, dump them on the market, and harm Bitcoin as a whole. It feels like he is saying if we do something, it's bad but if we don't do anything it's also bad.
