The basic idea is that each participant can distribute 'X' # of coins to every other participant in the currency. The caveat is that each individual needs to be held accountable for the choices they make as to who they "vouch" for when distributing currency.
That's not to say the amount distributed can change in some obvious way. My current thinking is that if person A, B, C say person X gets money, then they get the same "agreed upon" (or fixed) distribution as everyone else.
On the other end the coins that are created have a "depreciation" built in. Something that depreciates 100% in 5 years won't appear too valuable. But something that depreciates over the course of an entire lifetime will feel plenty valuable to the people who are the original recipients. So in other words my current target is 100 years.
