K320

K320 was the first coin deployed using Cryptokernel and serves as the current reference implementation. Its name derives from its monetary policy – Milton Friedman’s K% rule at a rate of 320 basis points or 3.2% growth per year. K320 is designed to build up the initial money supply relatively quickly then switch to the K% rule for monetary growth. Downloads of Cryptokernel come with K320 as the default coin though K320 is only intended as an example use of the library, and you are encouraged to use the library to create your own coins with more specialised features.
