Conclusion, I need to open the wallet.dat file with the good Bitcoin Core client... And I can't find it  Did you try extracting the addresses/wallets in it? I saw you can open it with a simple text editor or using a tool that do that automatically, there are existing (but be careful choosing/using a tool, it can be harming)! Do Bitcoin Core don't gave you the list of your wallets ?  You can just check the balances manually! I try to extract the addresses/wallets and the balance through the Bitcoin Core client. but for now it doesn't accept the wallet.dat file you can't open the file with a simple text editor, it's shows unreadable encrypted information. A tool for that? I don't know yet which tool but good idea! Do Bitcoin Core don't gave you the list of your wallets ? No : https://www.youtube.com/watch?v=recqagQ0Hss You can just check the balances manually! I don't know how but i think the may be corrupted according Bitcoin Core, so the first step is to salvage it. Thank you for your help |

Thank you for your help. I entered the command rescanblockchain and I got this : "Can't rescan beyond pruned data. Use RPC call getblockchaininfo to determine your pruned height. (code -1)" Conclusion, I need to open the wallet.dat file with the good Bitcoin Core client... And I can't find it That was the " prune block storage" setting that I was talking about in my first reply. You may stop the sync process now and disable the said setting; or if disabling isn't possible due to storage issue, only restart the sync once the target wallet is already loaded. Read that post for more info. But you know what is worst? I think that actually the Bitcoin Core 25 cannot open my 2011 wallet.dat file... I'm sorry to have misled you.
(I was misleading because of the text at the bottom of the video "sync with the network...3 years and 27 weeks" which made me think that the software use my file to sync it with the blockchain (while it's not)).

The error message which appear in the window : "Wallet file verification failed. "C:/Users/imwon/AppData/Roaming/Bitcoin/wallets/my old wallet 2011/wallet.dat is corrupted. Try the tool bitcoin-wallet to fix it or restore a backup."
That error has nothing to do with the Bitcoin Core version since old wallets can still be loaded to the latest version without issues. Bitcoin Core simply detected that it's corrupted. As per the message, you can try to use bitcoin-wallet tool to salvage " a copy" of it. ( make sure to keep an original backup) Here's the instructions: Try Bitcoin Core's bitcoin-wallet tool's " salvage". " bitcoin-wallet" is in the " bin" folder inside Bitcoin Core's installation directory ( where bitcoind and bitcoin-cli are located). To use it, open Terminal, cd to the directory where bitcoin-wallet is. Then use the command ( provide the full path to the wallet.dat file): bitcoin-wallet --wallet="E:\Folder\wallet.dat" salvage It wont return with any response ( unless it failed) but you will see a backup file ( wallet.dat.xxxxx.bak) where the wallet.dat is located. The new wallet.dat is the " salvaged" wallet. : - Depending on the binary, Bitcoin Core's bitcoin-wallet tool can be in "daemon" folder instead of "bin".
- In Windows11, in the step that mentioned "terminal", use PowerShell.
- To expand the "cd" step; "cd" means "change directory", here's an example to cd: cd "C:\Program Files\Bitcoin\daemon"
Thank you for your help, i'm going to try to do that. edit : indeed, it doesn't return with any response but it doesn't create the new salvaged wallet.dat.xxxxx.bak file : https://youtu.be/e4dC6526KCg |

I just clicked on file > open a wallet
-snip-
I just close Bitcoin Core and my Pc and I reopened them. I wanted to repeat the process but Bitcoin Core continues where it stopped earlier. It remains 4 years and 21 weeks :
You've properly loaded it, good. If you want to double-check, you don't have to repeat IBD if the blocks are intact, just rescan from block 0 and it'll scan those available blocks. Go to " Console" ( Window->Console) and type rescanblockchain to rescan with default args. I am sorry to be so ignorant but i don't know the wallet name. where does i find it?
I hope that a lot of spammers sent a lot of dusts
Old wallet.dat files don't have a specific wallet name. In the new versions, the wallet name is equivalent to the folder where it's located: ...\bitcoin\wallets\<wallet_name>\wallet.datAs for " dusts", it's usually those old addresses with large amount of Bitcoins are being targeted. Thank you for your help. I entered the command rescanblockchain and I got this : "Can't rescan beyond pruned data. Use RPC call getblockchaininfo to determine your pruned height.

You can use the following command to get the first address of your wallet (where 'X' your wallet name). bitcoin-cli --rpcwallet X getnewaddress I'm just saying this to save you time from syncing a wallet that contains no funds. If the first address does not contain any coins, try with the second, third and so on. Use a block explorer to check. If your wallet is loaded and you expected transactions made in 2011, there's no point letting it sync all the way since you're at 2016 already.
Maybe he received dust. Spammers like picking old addresses to spread their spam. Thank you Medusah  I am sorry to be so ignorant but i don't know the wallet name. where does i find it? and I write this command in the Bitcoin Core console (Window > Console) right? I hope that a lot of spammers sent a lot of dusts  |

What do you think? Should I shut down Bitcoin Core, or should I let it finish? If your wallet is loaded and you expected transactions made in 2011, there's no point letting it sync all the way since you're at 2016 already. Yes, I want to be sure. I read on the forum that the Bitcoin Core client may not see certain transactions even though they actually exist on the blockchain. |

What do you think? Should I shut down Bitcoin Core, or should I let it finish?
How exactly did you " threw in" your wallet.dat file to Bitcoin Core v25.0? Please describe the steps that you did. Depending on how you did it and its timing, if it rescanned or not, the blocks with the transactions may have been skipped. ( BTW, having no unverified transaction history at all isn't promising) Letting it finish is still recommended since you can rescan later, that's only if you didn't enabled " prune block storage" setting which would prevent you from scanning those old blocks without redownloading the entire blockchain. If you want to finish it, I'd recommend to disable the setting if it's enabled and start over. Otherwise, if you don't have the disk space, make sure that the wallet is properly loaded ( use "Restore Wallet") before starting over initial block download again. On a side note, the latest release version is v26.0 as you can see above the forum menu, but it didn't affected the result. There's no " official Bitcoin website" BTW. Thank you much for your answer and information. I was surprised too. I read everywhere that Bitcoin Core 25 can't read the old wallet.dat files, but for me it works. I just clicked on file > open a wallet :  The file has been created in 2011 :  I just close Bitcoin Core and my Pc and I reopened them. I wanted to repeat the process but Bitcoin Core continues where it stopped earlier. It remains 4 years and 21 weeks :  But it reaches 2019 so I don't think it is useful to go on  The "prune block storage" setting is enabled from the beginning (up to 2Go). Should I disable it now during the scan process? Or should I wait the end and then I do a new scan the the setting disabled? Thank you again |

Hello everyone, Recently, a friend and I were reminiscing about Bitcoin, recalling when we first stumbled upon it 13 years ago. Back then, we were both avid enthusiasts of the internet and computer technology but unfortunately didn't take things seriously. However, according to my friend, I was geeky enough to have bought some, perhaps around 20 or 30 bucks' worth. I have absolutely no recollection of purchasing any, but who knows, maybe I did. I might have bought some on a whim and forgotten about it; it's plausible. So, I dug up the old laptop from that era. It no longer powers on. I removed its hard drive and headed to a store to find an enclosure with a USB connection. I plugged it into my PC. I sifted through various files like "My Documents" (there are some cheesy photos of me when I was young ). I found nothing related to Bitcoin. I initiated a search in File Explorer and simply typed "bitcoin". After a few seconds, it pointed me to a Bitcoin folder located in AppData  . I opened it and found plenty of files undoubtedly related to Bitcoin. They were created or modified between June 22 and June 25, 2011. Well, that doesn't mean much; I must have installed the stuff back then without delving further. One file piqued my curiosity more than the others: wallet.dat. I tried to open it directly (lol), of course, it didn't work. I searched its name on Google, and then it all made sense... So, I went to the official website and downloaded Bitcoin Core client 25. I opened it and threw in my wallet.dat file. It accepted it gladly and began a search (synchronization with the network). The search started last night and still hasn't finished (it says it'll take another 2 days). No Bitcoin in sight. Bummer. The search is chronological, and it's currently at the year 2016, so it hasn't seen anything from 2011 yet. See the screenshot: https://ibb.co/5TGmj8WI have no idea about the public address, private key, or any passwords. I also searched for this information on the old PC. So, I conclude that it's a lost cause. Oh well, I dreamt for a few hours What do you think? Should I shut down Bitcoin Core, or should I let it finish? Thanks in advance for your advice. |

Bonjour à tous, Récemment, avec un ami on parlait du Bitcoin, quand on l'a découvert il y a maintenant 13 ans. On était passionné d'internet et de techno informatique mais avait pas pris la chose au sérieux malheureusement. Mais selon lui j'ai été assez geek pour en acheter un peu, genre pour 20 ou 30 balles. Je n'ai absolument aucun souvenir d'en avoir acheté mais pourquoi pas. J'en ai peut-être acheté sur le moment et j'ai zappé, c'est possible. Du coup, j'ai retrouvé le vieux pc portable de l'époque. Il ne s'allume plus. Je l'ai dépouillé de son Disque Dur. Direction un magasin pour trouver un boitier avec connexion USB. Je le branche sur mon PC. Je navigue un peu partout dans les fichiers genre "Mes documents" (ya des photos de moi jeune ). Je voir rien de lié au Bitcoin. Je lance une recherche d'explorer et je tape simplement "bitcoin". Après quelques secondes, ça m'indique un dossier Bitcoin, localisé dans AppData . Je l'ouvre et je vois pleins de fichiers qui à coup sûr sont liés au bitcoin. Ils ont été créés ou modifiés entre le 22 et le 25 juin 2011. Bon ça veut rien dire, j'ai dû installer les trucs de l'époque sans aller plus loin. Un fichier attise plus ma curiosité que les autres : wallet.dat. J'essaye de l'ouvrir directement (ptdr) bien sur ça marche pas. Je tape son nom sur google et là je comprend tout... Je vais donc sur le site officiel et je télécharge le client Bitcoin Core 25. Je l'ouvre et je lui balance mon fichier wallet.dat. Il l'accepte avec plaisir et commence à faire une recherche (synchronisation avec le réseau). Recherche qui a commencé hier soir et qui n'est toujours pas finie (reste encore 2 jours parait-il). Zéro Bitcoin à l'horizon. Snif. La recherche étant chronologique il en est à l'année 2016 et donc il n'a rien vu en 2011. Voir le screenshot :  Je n'ai aucune idée de l'adresse publique, privée, de clés ou mot de passe. J'ai aussi recherché ces informations dans le vieux Pc. Du coup j'en déduis que c'est mort, tant pis j'aurais rêvé quelques heures  Selon vous, Je peux éteindre Bitcoin Core et je le laisse continuer jusqu'au bout ? Merci d'avance pour vos conseils. |
