- The wallets page does not seem to mention Open Source, GitHub, compiling yourself, etc. I found the source code on GitHub, but it hasn't been touched for almost a year.
- The website does not use https, so literally everything users see / download there could be replaced by a MITM effortlessly.
- The Android wallet is not on Google Play. Instead it is just an APK file to download from the website (see item above).
- Did not find GPG keys or digests for the files, so installing any of these is really dangerous (especially for anyone who might have another cryptocurrency on the same system like people here).
- The Linux binary on the website has no file extension. Not a big deal, but makes me wonder if anyone has ever downloaded and used it.
I have some questions about the economics / distribution, but need to read & think more. :-)
I have looked into this coin myself and had these concerns as well as the business model of the coin itself. The idea is nice and all but i'm not exactly sure how the execution is going to work, perhaps i'm not fully understanding how it all will work. That being said, I do actually want to see this one succeed because well, the cause seems noble and can actually help some very poor people in their lives.
The economics and distribution of UBI are very important considerations. A review of articles on UBI challenges and proposed solutions has led me to believe that the technical and practical aspects of UBI can and will be overcome within the next 6 to 12 months. Searching "Universal Basic Income think-tanks" led me articles and sites where many very smart people are working through many of the challenges. Fortunately cryptocurrency provides a viable solution for both distribution and decentralized control.
One of the largest remaining impediments, IMHO, is pushback from national governments, central banks and the rich/powerful everywhere who have greatly benefited from the current systems and practices. A new income system that reduces the power/control of those who have it is likely to face significant resistance from those same people and institutions. A second and equally formidable challenge will be changing the mindset of the masses in some countries. In the USA for example, the concept of income is very tightly bound to "earnings" or "holdings" - many people would argue that UBI equates to money for nothing and would promote laziness and/or idleness. Changing deeply ingrained mindsets can take a very long time.
However, there is a storm on the horizon that may force societal change and almost everyone to rethink UBI. The advancements in AI and automation will displace millions of workers globally and ballooning debt levels/fiscal crises will devastate many fiat currencies in the years ahead. This trifecta of upheaval may spark widespread discussion and ultimate acceptance of UBI (hopefully) or civil unrest/state collapse/failure of national governance (bad times for all involved). Let us all hope that viable UBI such as Manna comes to fruition in the near-term to prevent widespread catastrophe in the long-term.
