If there is another coin that wants to try to raise donations and have this design be exclusively for this coin, then make a serious post in this thread how you plan to achieve that.
Are there any specific requirements for a coin's protocol / blockchain etc in order for the feature to be feasibly implemented? Does it need to be a Cryptonote coin, or could it be implemented on DASH (former Darkcoin) for example?
Afaics, the only requirement is to be able to refer to UXTO for the inputs to the rings, so a balances only design wouldn't work.
A huge advantage over Cryptonote rings, is you don't have to use equal denominations, thus you radically simplify wallets and reduce block chain bloat significantly. So this makes it much easier to integrate than Cryptonote because you don't have that complex simultaneity requirement on powers-of-ten UXTO.
I haven't studied Dash/DRK, but I assume it has a UXTO (unspent transactions outputs).
It might not even need to be a hard fork, depending on the block chain format's flexibility, but unlikely.
Hey if Dash wants to pay me more, then I will go to the highest bidder. That is the nature of a free market. I haven't earned an income for many years. I really need it. Even my 2003 model year SUV is starting to fall apart.
Edit: I am giving up one of my jewels because I am really in a bad financial situation. Not only health, but I have negative networth right now. I am living off cash my angel investors gave me. I want to create some buffer of savings if possible.
