This package is part of the arch community repository but currently only available for x86_64 machines.
I will try building this soon and see if it can be built on aarch64 ... it only needs git cmake and boost so should not be a problem ... I think. I do not know how to build proper arm PKGBUILDs though, so posting here.
EDIT:
Can confirm can be built by just downloading these files and adding aarch64 to the PKGBUILD (you might need to import gpg and set trust - I did that in forward). Also tested downloading blocks, works.
