I ask a stupid question..... if I put together 130 virtual machines (not a problem for me) , send coinbase transactions created with these private keys and have them authorized by the 130 machines, do you think it is feasible?
You could put up a million virtual machines and it won't matter for the consensus blockchain of the one and only Bitcoin, because you can't undo and recreate the proof of work of more than 855,000+ blocks. (I just eyeballed the amount based from the blockcount of your stale chain...)
It sounds like you might be dealing with "stale" blocks or unconfirmed transactions. In the early days of Bitcoin, some mined blocks didn’t get added to the main blockchain due to the lack of network participants, which may explain why you see the mined transactions but they aren’t showing up in the blockchain now.
His transactions aren't unconfirmed. They are all confirmed in a stale branch of his own blockchain which isn't the consensus blockchain. It very much looks like his blockchain isn't the one accepted and verified by the majority of Bitcoin nodes.
If you're still having issues, you might want to reach out to a Bitcoin recovery service, but be cautious and ensure you're working with a trusted party.
If his transactions and blockhashes aren't known to the consensus blockchain, there's nothing to recover. Don't waste your time on that.
