i became unhappy with the usual go PRNGs including salsa and the like. Despite knowing about being foolish to take such a task i did create a deterministic chaos based random generater (CBRNG) that produces random bits (tested with the NIST package) and is faster than go’s standard random generator, salsa20 and of course way faster than go’s crypto/random package.
you may find this and a lot of information about the how and why and however else and speed …

and there is a pdf summary too: https://github.com/AndreasBriese/breeze/blob/master/breeze.pdf
!! Do not oversee the fact, it is not so far cryptoanalysed by any third party !!
