Is there a default password that may have been saved from an earlier client that I messed around with a few weeks ago? (I installed the cpp and the go clients 8.6, i think)
Today, I installed the latest updated version, but when I started mining, I was not prompted for a password. I have mined 30 or so ether with the mist gui and then with the geth console(on ubuntu), but I can't seem to unlock them now. Should I erase these wallets and start all over? Is there a length of time before a block matures so you can spend your mining rewards?
