There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

If the recieving address is empty. There’s probably a good chance there wipers to any funds to start with in that wallet since it said it’s been able to load keys alright.
I might be completely wrong but this is just my interpretation. Maybe a copy of the debug log for the second instance might be helpful? Open command prompt and type notepad D:\btccore\debug.log and post it here?

Use pastebin.com or a similar service. I doubt the majority will download a file just to look at your debug.log.

On receiving address tab all is empty.
Looking at the dump, your node is crashing after syncing at block height=237172 And it also seems your wallet.dat is corrupt or in old format. The fastest and quick/dirty way is open the wallet.dat with nodepad (PC), texteditor(mac) or gedit (ubuntu) Search for the string "name" and after that you should see a 34 character string starting with "1" which is most probably a bitcoin address which you can check balance online with blockchain.info Another step I would recommend is to download pywallet from github, https://github.com/jackjack-jj/pywallet which can parse the wallet for you and see what version, addresses etc. There is also a web wrapper on port 8989 so its much easier to use. If you have a PC, you can check your ip in a terminal with ipconfig, then use that ip, like 192.168.0.10 and add ":8989" in a browser and you would be able to open the wallet with a friendly interface. You would first need to run pywallet with "python pywallet.py -web" to start it. Then in a browser type "192.168.0.YOURIP:8989" You could also try to run this command: python pywallet.py –dumpwallet -datadir="yourpath" > wallet.text --passphrase= PASSPHRASE to try to dump it. Third step would be to try to "fix" the wallet which is saving data which can be saved, you would need to run the bitcoin core start command in a terminal with the command option "-salvagewallet" ,it will make a dump of whatever is correct data. If you need more in depth guidance on any above, just let me know. /KX

Yes, Python is required to run pywallet. The version you need is 2.7, you can find it here: https://www.python.org/download/releases/2.7//KX

Regarding pastebin, you dont need pro to paste the log, just register, its or free
You need when you're pasting a big file (bigger than 512 kb). Just check the image OP posted above... Actually, even with PRO he wouldn't be able to do it. His file is 16 Mb and Pastebin PRO only allows 10 Mb files.

If it's encrypted you need to install the wallet to see the addresses, but then you can just copy them and check online instead of downloading the entire blockchain. Source: https://www.reddit.com/r/Bitcoin/comments/7o3cob/quicked_way_to_check_walletdat_address_balance/Another user had a similar issue and that was the solution from reddit.

@ETF this probably calls for the use of pywallet, and failing that, a check to see if there are any other wallet.dat backups from around that time that might hold the uncorrupted private and public keys. EDIT: actually can he not just hit the new address button? Won't that show his original addresses that are next from the keypool? @keychainX, you've just essentially posted something that means he can shut down core

On receiving address tab all is empty. If you or your friend is poking around a "found" usb with btc data...on a computer that you use regularly and/or with your personal wallet on it, there's a really good chance that you'll soon be back here posting about how your wallet was hacked. If I was you and had a wallet on a computer that you plugged that usb into, I'd move the funds to a different wallet on a different computer of phone, STAT. You dont mention it, so I assume you didnt do this: anytime you find a USB and want to see whats on it, you should use a "live CD" boot on your computer.

In this laptop i don't have any wallet, and the usb stick belongs to my friend. I use hardware wallets anyway. keychainX can you tell me steps i should follow now and what to do to see address?

try this (datadir is where your wallet is) python pywallet.py --dumpwallet --datadir=/tmp | \ grep addr | sort | uniq | awk -F'"' '{print $4}' > \ ~/tmp/wallet_dump.txt If you want to see the value for each address, do this python addrep.py ~/tmp/wallet_dump.txt /KX
