The transfer in question is confirmed as having already been processed and credited to recipient's account as of Fri 13 Jan 2012 07:12:25 PM JST. Please be aware that transfer to 1JcMWSggw3mnFanp81HMeBCtKyFJwJ253S is an intra transfer. When BTC is sent to another Mt.Gox address, the transfer is done instantly and will not appear on the BTC network.
First I should say that the recipient is not me it is the person I bought the board from. So it is his word that the bitcoins did not show up at his address.
How does this work? Does MtGox have their own block chain? When I sent to that address did it appear in MtGox's block chain but not the one the real world uses? When I sent 5.9 BTC to that same address and it appeared is that an address in a different block chain? Will that 11.1 BTC never show up in the Satoshi block chain?
Where should the recipient look to find his bitcoins? Does he posses them? Can he spend them? Have I successfully paid for the board?
If MtGox has their own block chain can I see it?
If the answer to any of these questions is yes then that is just another complication to bitcoins that will make it's wider acceptance difficult.
