Freicoin has 80% seigniorage towards a central foundation. It makes for an interesting demurrage test case, but any city should be using a coin that's 100% peer to peer. That means equal rules for all participants, not an unelected cabal spending most of the coins on their own pet charities.
I thought this was Devcoin. Does Freicoin also have this?
Yes. They don't advertise this feature very prominently, but they're going to spend 80% of the initial supply on charity. All other participants are allowed to compete over the remaining 20% as mining subsidy. They added this right before the official launch, but so far they haven't decided which charities will receive it.
So... should the economy of Detroit depend on the security of a single cold wallet, or the authority of an unelected private foundation?
