Out of sheer boredom, I have created a cryptocurrency. Here's the spec:

PiCoin (PCN)
π

Totally pointless crypto-homage to the circle.

Block target of 3.14 minutes
Block payout of π3.14159265359
Coin Maximum 314,159,265
Difficulty adjusts daily
120 confirms

Windows users will have to build from source


Gotta say, it was fun. I do need people to download and mine with it though.
