Speaking as maintainer of the Python library python-bitcoinlib, I don't thi=

using Python for security critical codebases is a good idea. It's just too =

to make mistakes; I wouldn't recommend new projects use python-bitcoinlib.

Currently I'm doing 100% of my new projects on Rust. That's not to say Rust=
 is
the only language usable for this kind of work. But it fits my style of
programming well and the type system - esp good handling of immutability -
appears to offer significant benefits.
