Bitcoin Forum

Omitting the characters you have likely still makes you identifiable (especially since block hashes are quite easy to search through if you've got the blockchain in front of you).

You could try taking out the private keys and exporting them into electrum (from electrum.org) but if the address doesn't have funds on a block explorer, something else might be an issue (perhaps if you've spent the coins or the block didn't broadcast correctly).

You could also install an up to date version of bitcoin core for the best privacy but it might need a lot of time to sync and a lot of bandwidth.

I don't really understand what you mean by "it takes 10 years to update".
Are you trying to download the blockchain in bitcoin core and it says it takes 10 years to be synced? If so, it shouldn't take that much.


No.
Either you don't have bitcoin at all or you are looking at a wrong address.

According to the data you shared, the 50 BTC have been mined in the block number 4111.
Bitcoin generated on that block haven't been moved at all and are still in the address 1C7JtZUBeSPy7eZQ9vuCcaHRzYjKmnXACJ. This address doesn't match what you shared above.
The transaction ID you shared above is also different from the hash of coinbase transaction of that block.

Where did you take this data from?

1. No. If you have received (mined) this block you have already received it... and of course are visible on blockchain.
2. Blockchain is already updated. You can just check from any laptop.

Try to recover your wallet using electrum or bitcoin core as already suggested by jackg

Coins from this block have been moved with such tx on Jan 2021

coins have not been spent. here original coinbase. thank you @hosseinimr93

You are looking at a wrong transaction.
In the transaction you shared, 17.61386661 BTC has been sent from a segwit address.

According to the data shared by OP, the 50 BTC have been mined in the block number 4111. Click here (https://www.blockchain.com/btc/tx/394f36eb9ff916a3e913444f7fd32c0e1593134d648d2fdb2f84ab8efa441fc5) to see the coinbase transaction of that block.
The 50 BTC mined in that block is still unspent.

Thank you for the tips, Jack!

• 1. I do have another machine (macbook) with bitcoin core full synced. Do you think is safe to import his private key on this computer?
• 2. There is no transaction on his wallet. I hope it was not broadcast correctly. Is still possible to recover?

• 1. Is possible to have "broadcast" problem because of outdated computer?
• 2. How did you get the Block and this Wallet Address?

My friend send this data from his computer (I think it is the miner's software output)

Don't worry about broadcasting your transaction.
First, you should know whether you have any bitcoin or not. If you really have bitcoin and you own the private key, you will be able to spend the fund.


From "blockheight": 4111
As I said above, the data you shared doesn't match the blockchain.


What's the name of the software?

If I do have private key, what is the next step? Import it into full synced bitcoin core, right?

How do you filter the block by blockheight? is there any website/script?

I will figure out the software's name...

Exactly.

You don't need to do that. Importing the private key will suffice to get access to those funds again.

Just open the console window in Bitcoin-Qt (if you use that) and enter: importprivkey <your private key>.
If you run Bitcoin Core on command line, it's bitcoin-cli importprivkey <your private key>.

You may need to reindex the blockchain after that though, to see your updated balance.

What's is


 ???

in my mind should be something like "nonce" (number used once)

Each transaction has one or more outputs (just as it has one or more inputs) and each output has an index inside the output array. The index of the first one is 0, next is 1 and so on. "vout" is that index here.

If your computer is clean and isn't infected with a malware, yes. That' safe.


Yes.

Both should work. Of course, if there's any bitcoin.


If you are going to import the private key of this address, it will be useless. Blockchain doesn't lie to you.


That simply means that there is no transaction with that ID at all.

Doesn't the gray font with the address between brackets mean it's not confirmed?

That doesn't add up with this though:
Text is easier than screenshots, I typed this: 8202144d4cdb2340497c8a69ec805b27e49553f66da531c6c8f6a5eaa359751f, which doesn't exist.

Bitcoin was less than 2 months old back then. Any chance you bought the wallet instead?

Take note that you might get false-negative result in Electrum because coinbase outputs at that time are P2PK by default, unless mined using other software.
Means that Electrum might see zero transaction despite having a valid transaction;
if you want 100% accurate result, you need to at least sync Bitcoin Core for a few minutes or until it reached beyond that block's height.

However, taking all the available info in consideration, your 50BTC may just be from an orphaned block (not in the blockchain).

care with electrum, download correct version, be aware from fake/cracker server

as @bitbollo said I can give you a hand
I'm not as good as Dave, but my fee is lower than Dave's

I can do the work you request cleanly, quickly and seriously

Removed content due sensitive data

What's shown in block explorers is definitely correct. If you don't see any transaction, it simply means that the address has never received any bitcoin.
Even if you download the blockchain and your wallet is synced, you won't be able to spend the fund which is not yours. The transaction you see in bitcoin core doesn't exist in the blockchain.

You didn't answer the question asked by LoyceV above.
Were you really mining bitcoin in 2009? Haven't you purchased the wallet file?

The only way to be 100% safe, is be syncing the new computer, then taking it offline before you copy wallet.dat. You don't need to copy your old database files, only the wallet.

Did you or your friend ever see those coins in your Bitcoin Core back in 2009 or did someone send you those screenshots? Maybe the same person who sold you the wallet? If in fact you bought it. I find it hard to believe that someone was mining Bitcoin that early on in its existence but is struggling to understand how to work the private keys and can't point out his address. But exceptions do occur.

need to copy only wallet.dat (like other said)
you can use it in a blank bitcoin-qt and extract priv keys of address with money without download all blockchain
after u can use this private key for swipe content and send to another address

this is the correct way to do without broke nothing

The bitcoin was mined in March/2009 (I know it hard to belive) so, i think due the outdated computer it was not put on the blockchain yet... is it possible?
If it does, how the safest way to put it back to blockchain, by updating blockchain on computer right?
How do it with new computer, which files do I need to move to new computer?  

We did not purchased anything, it really was mined.

No, that's not possible. You could have created an orphaned block, which explains why it's not confirmed in the first screenshot. But that doesn't make sense since your other screenshot shows 6246 confirmations, and that doesn't make sense because the block you mined doesn't exist.

You're 13.5 years too late to add block 4111 (https://blockchair.com/bitcoin/block/4111).

Something must have gone wrong, the block you mined never made it to the blockchain.

In addition to what stated above by LoyceV, block number 4111 was mined on February 13, 2009. In the data you shared, the block time is 1237118551 which is March 19. In the image you shared the date is March 02. In March 2009, you were trying to mine a block which had been mined and broadcast to the network in February by someone else. Most probably you didn't mine any bitcoin at all.

Sure, as long as your new machine is not compromised, it's safe to do. Importing the wallet.dat might actually be even easier, since you don't need to export and import all keys one-by-one.

This is not how Bitcoin works. The very fact of successfully having mined a block and receiving the block reward, requires having published a valid block to the blockchain. You can't receive the block subsidy without publishing anything. Furthermore, coins don't actually exist 'on the computer' at all. They only exist on the blockchain and the keys simply allow you to spend them.

Do you think is possible to fake those data (Edit wallet.dat or something like that)?


I saw the computer and the bitcoins are there. it is NOT photo edit.

There have been many people who have fallen victim to fake wallet.dat files. Scammers usually sell those fake files to those who want to get rich quickly.


Bitcoin are stored on the blockchain, not on the wallet. What's shown on blockchain explorers is surely correct. It's possible that what you see in your computer is wrong.

It was too easy for newbies actually, just have to download "Bitcoin" which was exclusively for Windows, then tick "Option->Generate Coins" and pooof... it's mining.
If his "friend" is honest that it's not bought, then I think they accidentally made a fork back then and mined a block in their own blockchain.

Copy the wallet.dat from bitcoin's data directory (en.bitcoin.it/wiki/Data_directory#Default_Location (http://en.bitcoin.it/wiki/Data_directory#Default_Location))
Paste it to the new PC's "wallets" folder inside bitcoin data directory, rename the wallet file or put it inside a folder with your preferred wallet name
then Open Bitcoin Core and load using the menu: "File->Open Wallet".

You don't have to put it to a fully synced Bitcoin Core since it's only @4111 which is a few (nearly)empty blocks away from the genesis block.
After getting past that height/block timestamp, you can immediately see in the transactions tab if your generated bitcoin is verified (with check) or invalid (with questionmark)
Spoiler: hover-over your mouse pointer

You can fake anything on your own computer. That's why you should load the wallet in a fresh Bitcoin Core installation, see which addresses are funded, and see if it has the private keys to those addresses.

You said that you mined coins, you said you have seen wallet with coins, then you ask if it is possible that wallet is forged.
I do not understand - if you KNOW you mined coins, you know that it is possible that wallet has your coins. Do you suspect your friend to show you forged wallet?
What is the story behind? Computer was off-line for a decade and now is suddenly on?

I feel like we're being lied to here.

My intuition is telling me that the OP (or any friend of his) did NOT mine a block in 2009 at all.

What my intuition is telling me instead is that someone is trying to trick the OP into believing that THEY mined a block in 2009.  Perhaps the person the OP is communicating with is attempting to sell a fake wallet to the OP, or perhaps they have some other scam that they are attempting to perform against the OP which depends on fooling the OP into believing that they possess a wallet with a mined block from 2009. Either way, I suspect that the OP didn't want to admit where the wallet came from, so they instead made up a story about a friend mining a block.

For what it's worth; the internet never forgets.
