Hi everyone, so I've been looking into Bitcoins for about a week now and was wondering, which Bitcoin miner came first? I've already done the basic googling and searched the forum for it, but no answer, so I'm starting a thread.

As I understand it, Bitcoin miners are the programmes that are adding to the block chain, then the Bitcoin client checks the blockchain for validity etc. I don't know if the miners check the blockchain too, but that's not entirely relevant. So, if its only the 'miners' that are adding to the blockchain, to start the blockchain, one of them must have come first/been developed by bitcoin.org. Which one?
