damn from 4GB to 13GB in less than a year.. seems like a solution needs to be drawn up relatively soon. by this time next year, that number could easily be 30GB.
There is a solution. It's called quark coin.
Google quark coin , first result:
"At Least 54 Bitcoin
Clones Have Been Created Since April"
So , what does it do , have Kermit jumping up and down and reducing the blockchain?
