Is there any code available online for the chaos-based hash algorithm CHA-1?
I am trying to apply the methodology of this paper to blockchain applications.
This is an obscure and not peer-reviewed article of dubious quality (I'm being polite). It has far too many flaws to list here. It should be best left ignored. The author did not publish a reference implementation, and the software they used is most likely just a proof-of-concept, not usable in practice.
