We use libbitcoin in our app, and are currently under review to have it posted on
bitcoin.org. It was brought to us that we aren’t using a CSPRNG, rather libbitcoin’s native PRNG. Looking into it further, I found a way to get secure data from Libsodium, but I wasn’t sure how to go about adding it via PR to the project (or if it would even be a solution that should be added)
