For those not aware, the original 50 coins sent to this address were generated from the genesis block, the first block on the blockchain. However, the transaction is still unconfirmed, so until it is this could be nothing. Market has been scared downwards though.

I don't understand. Either this transaction has a valid signature or it doesn't. If it does, then AFACIT the only possible way that it could not be confirmed sooner or later is if it's a double-spend. What am I missing?

  Maybe blockchain.info generates its web pages from a database, and someone inserted a record into the database that doesn't correspond to a transaction with a valid signature? Although if that's the case you would maybe expect them to not mark it as "unconfirmed".

    But surely someone would have just checked the signatures on these transactions by now? (I would do it myself but I'm not familiar enough with the bitcoin transaction format.)

      They're definitely invalid transactions. The public keys and signatures do not match the address they're trying to spend from. Only blockchain.info failed to detect this minor detail.

  Good point! I clearly wasn't thinking like a computer scientist this morning.

How do you determine that is from the genesis block? Also how do you know it is Sataoshi's? Because it is from the Genesis or is there some other method?

    The genesis block is actually block 0, you're looking at block 1. Incidentally, the genesis block reward is unspendable. It's not really known if that was intentional or a bug in the initial implementation, but the rule persists.
