MarsSeed [1] filed a deletion request for onyx-bin [2]: Orphaned package for experimental app discontinued in 2018.
It was meant to be a messaging app with strong security and privacy, based on the Ethereum Swarm's PSS feature. As it never reached production quality, it is likely insecure, if it works at all (didn't try). I think it is not useful to keep this AUR package for such abandoned alpha quality software. There are numerous working alternatives for messaging and online collaboration. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/onyx-bin/
