Gold Medal: Peercoin
I like this solution the most because
it is the simplest. Simple solutions
are usually the best, which is why
proof-of-work and longest chain has
stood the test of time.
It would be nice to see if Peercoin
would work without checkpointing.
Geniuses simplify things...
While merely highly intelligent people complicate the shit out of everything...
(See Ripple, most 2nd Gen Crypto Assets, etc).
Twitter is genius... because it's dead simple.
This is why PeerShares could sweep away the Pretenders...
Sunny knows that "good enough" and "dead simple" wins.
