Currently I don't have an up to date version of the real/test net on my PC. I've tried to find a blockchain explorer that will show the size of the chain in GB. Specifically for Geth, or atleast for any other clients.
Question: To date what is the current chain size in GB?
On reddit one person told me the blockchain is 140 GB. What is recommended is to run 'geth --fast console' which will get a version of the blockchain which is only 12 GB. The fast version just contains the headers... I think most people are running this version.
