Another really n00b question, apologies... can someone explain to me how to read BlockExplorer.com... like which addresses mean what? For example, on
http://www.bitlotto.com it says you can send a payment (the winnings) back to the person who sent the winning ticket bitcoin... so I assume another address is created which is associated with the sender of bitcoins? so confusing
I tell the person they HAVE TO send using Bitcoin software on their computer. Since Bitcoin sends payment from only addresses they own, I can send some back to the identical address because they own it. I don't need to know who it is! Only the owner of the address! With ewallets such as mybitcoin those addresses/keys are all shared.
