Can someone help me understand this situation a bit more?
https://blockchain.info/tx-index/81601637I was supposed to receive 92.85$ in BTC from 14YUJhQ8oT3YEuqyHWP9XGG4cBLsgWynVj
As you can see on the right.
But that transaction has disappeared from both his, and my transaction history.
I can follow the output history on the left, and see that he somehow was paid with double spent money and that's why my transaction got clogged.
But the part I am very confused by is what happens next or how do I fix this?
It appears my transaction has disappeared, but I don't think he got his money back? If he didn't get it back, and it never confirms(goes2me) then
how does he get it back or the transaction go through? I am using BitCoin Core if that matters, and this was my receiving address.
https://blockchain.info/address/14W25e9yWK3ReBWSHnjV6Jgorn5JC6UwxQshorena explained it nicely, but your transaction was dependent on other transactions. It seems someone was either trying to scam you or trying to scam the person who was supposed to be sending you the bitcoin.
As far as "how does he get it back" - bitcoin is not really "in" an address, that is an abstraction and it isn't ever in limbo between one address and another. It is based on inputs and outputs, so he won't have to "get it back" since it doesn't go anywhere. It is either spent or unspent. So if the long chain of transactions was all in his control, he never lost the money. If the long chain was from someone sending to him, then he'd have to talk to the person who sent him those transactions.
Right now it looks like only way to fix it is to have him send you bitcoin that isn't dependent on other transactions that are double-spend attempts since as shorena noted, one of the transactions in the sequence has many confirmations.
, I think I understand most of it now.
