So out of curiousity, did anyone ever hit a non-related funded wallet during puzzle solving?
You would have to check the balance of each private key. It would slow down the brute forcing to a crawl. I highly doubt there are any funded wallets in the keyspace, except for some dust in some test wallets that people made to test their bots. What odds would there be if during solving we could check for a known address? For example, i have a locked multibit wallet since 2016-ish, could all combinations be checked against this address should i decide to solve a puzzle? |

So it makes me wonder if those QR codes are actually my wallet, or maybe they are just the blocktrail pubkeys as third party of the 2-3 signature
One thing's for sure, Blocktrail/BTC.com never issued P2PKH to their clients, it's always 2-of-3 MultiSig. So, it's either what you're guessing or the funds are just sent to the derived P2PKH address unintentionally. ( like imported the xpub to a wallet and used it to receive BTC) Is your backup V1 ( developer)? Since it has that extra blocktrailKey @m/9999'. In that case, I'm afraid I'm not familiar with the developer version which may be different than V2 or V3 backups. Try to contact neutraLTC to check if he knows if the V1 blocktrailKeys are recoverable from your backups mnemonics. @others Those mnemonic phrases in the backup aren't actually the BIP39 seed phrases of the MultiSig wallet. Those are actually what is " labeled" but converted into a BIP39 mnemonic. In other words, deriving the seed from it isn't the correct way to get the master key and extended keys, the source entropy must be derived from it instead. Examples: Encrypted Primary Seedlibrary fantasy right giraffe impulse believe unique puppy rain amount abandon above cotton lottery cash exclude bicycle hamster pair clock edit picture two guard supply shadow wife maximum tired lion speed cruel draw knife brave wheel pumpkin foot plate involve eight guide mule carbon valley enroll grow town enemy sunset power regular allow cycle plug expose immune output pave result
The source entropy is, which is the " Encrypted Primary Seed": 810a62e7311722297b6570b101000000430d0808d27715ed167c15b46748baeb3ad9d89bebc4be2b047441a4426f746d7d0adab5e98bb146ecf245113f0e9659c73249fb32a55a606a6da9b28571b3ae Backup Seedscissors census engage duty alarm salon cabbage benefit two sudden service whisper organ caught whisper much symptom fire radio sadness faint tip write illness The source entropy is, which is the " Backup Seed" ( backupSeed - 256Bits): c104a92922405d7d07e8a9ebbb1310fd49c648fea488dc8ae6c35ef51fc53fa3 Reference: https://github.com/blocktrail/wallet-recovery-tool/blob/master/src/libs/blocktrail-sdk/docs/KEYS.md#print-recovery-sheetThe wallet is V3 My guess is still those QR codes show the pubkey for the blocktrail wallet, and i don't have those xprv keys to those. |

 https://imgur.com/a/AvVOivzAs you can see, when i import the XPUB by itself, i can see the funds. Once i import the same XPUB as 2-of-3, there is no balance showing up. |

It' impossible to contact support.
I noticed it uses Insight API and blocktrail API to recover the wallet, but since those are both out of service, i guess my BTC is lost.

I directly imported the PDF file. Also tried manually entering the pubkeys. Main issue is that it doesn't generate the same XPUB as displayed on my QR codes. I tried new wallets generated by their SDK, the same thing happens. So it makes me wonder if those QR codes are actually my wallet, or maybe they are just the blocktrail pubkeys as third party of the 2-3 signature |

Do you have the private keys or the seed or anything else like what is shown in your link?
The XPUB is your public key, there is no way to recover anything from it, all it does is generate addresses that your private seed can access.
You need the private keys or recovery phrase to do anything.

Hi everyone I found an old blocktrail.com wallet recovery PDF sheet. (As example, here is a public version on google https://www.scribd.com/document/433450775/bitcoin-recovery-key) Now i have a couple of questions: First off, i have 2 QR codes with an XPUB and derivation path. (m/0 and m/9999) When i scan the second QR, the XPUB shows a balance of roughly 2 BTC on a P2PKH address By using the recovery tool at https://recovery.blocktrail.com/, i noticed the addresses are generated in P2SH and no balance is recovered. So my main questions are: - What do those 2 QR code represent actually? Are those real public keys, meaning i still have those BTC in my wallet? - How can i recover the wallet as P2PKH to actually access those coins? I've been through the entire blocktrail SDK, there is only the option to extract scrypt based xpub/xpriv. Thank you all |

Pollard Kangaroo approach is for the know private key range and for the best, within 125 bit range and of course since you have the Multibit wallet handy all you have to do is "Once you located the files, if you have access to an old multibit app on you computer you need to import the wallet and export the private keys to a new wallet. If you do not have a copy of Multibit, you can use OpenSSL together with your password to decrypt the files and recover the keys."
You need the password to export them. I still have the wallet open every single day since then. I just keep looking at what value i've missed out on  I'm confused, do you have the wallet or you don't? How come the wallet is lost and you have it open? Maybe I'm missing something here? All info can be found on github here https://github.com/gurnec/btcrecover/issues/212I've also posted the hash if anyone wants to take a shot at it, i offer a 5 BTC reward. |

Have you tried hashcat yet?
Wish you find your coins, good luck.
I've spent close to 250k since 2014 on this, so, yes. Bruteforcing is no option. Dave succesfully recovered a wallet holding +- 1800 BTC around the same time (lost all passwords the same day), so i know he's a capable guy. If he tells me after almost ten years it's impossible using the bruteforce technique, then i trust him. I guess i'll wait it out until our technology evolves. |

I have experience working with multibit wallets. Maybe I can help.
The wallet itself is lost. Dave Bitcoin has been working on it since early 2014, bruteforce of the entire range up to 10 characters has been attempted. At one point, KeychainX found a false positive using the words i gave him, but it was just that - a false positive. My only remaining options at this point are to handle this like solving the puzzles, but with my own wallet

hi members!
I have a multibit classic wallet that currently holds 17BTC
Somewhere in 2014/2015 i lost my wallet password.
Many attempts have been tried to bruteforce the wallet password, without any success.
KeychainX, dave bitcoin, everyone already tried to guess or break my password.
Would you asume there is a possibility to use software to try and recover my wallet using the Pollard approach?
Can someone point me in the right direction on what sofware and settings i should be using?
I still have access to the Multibit wallet, only the password is missing.
I have my wallet address and it's public key.
Maybe this could come in handy to extract certain transaction data?
Thank you

Be careful, it's easy to tamper with wallet files and show incoming transactions, unspent funds. Why don't you feel comfortable posting your address on the forum ? Because it doesn't have 17 BTC in it ..?  Feel free to DM me, you can even teamviewer onto my computer to verify the wallet, no issues at all. The reason why i won't post my addresses in public is exactly to avoid people claiming they have my wallet and scamming others. My wallet is 100% real and can be verified by anyone intrested in making an offer. |

@ wie mij kan helpen ..... Sinds eind 2014 heb ik een probleem met het openen van mijn beveiligde wallet in Multibit (versie 0.5.17). Op dit moment is er een bedrag van 2.439 BTC opgeslagen in mijn wallet en deze kan niet geopend worden vanwege wachtwoordfouten. Ik ben 100% zeker dat het juiste wachtwoord is gebruikt, maar deze wordt niet geaccepteerd. Alles wallets (tijd backups), ook de UNC backup zijn ge-encrypt. Heel vreemd, want ik weet ook bijna zeker dat ik wallets heb bewaard zonder encryptie (om juist dit te voorkomen)!! Helaas had Multibit in die tijd geen seeds ingebouwd, en kan de wallet dus ook niet op die manier worden hersteld. Ik heb al diverse acties ondernomen bct-recover, multibit_recovery van Githib, via 6 GPU's getracht het wachtwoord te kraken, maar helaas geen succes. Wie van jullie kan mij helpen met het terughalen van mijn bitcoins. Voor diegene die het lukt de wallet te openen, krijgt 20% van het aantal aanwezige bitcoins (0,486 Btc) - Het bitcoin adres is 1Dk2EvmoYanKYEsmzLRrApsrfskhRe3S7L - Via https://www.blockchain.com/btc/address/1Dk2EvmoYanKYEsmzLRrApsrfskhRe3S7L?page=1 kan de huidge waarde worden bekeken. Plz Help, Felix Gelukt? |
