MarsSeed [1] filed a deletion request for lux-qt [2]: This cryptocurrency project was abandoned mid-2021 [a], then the creator forked a completely different blockchain and renamed it to newlux [b]. But that fork was also abandoned in Nov 2021. Project website is dead, domain parked. [c] There is just one, albeit duplicated comment in AUR, from 2019, about build failure. Package was last updated in 2018. Seems this was one of the myriad of short-lived cryptocurrency projects during the heyday of its hype.
