To clarify to the OP: in Electrum, when sweeping the private key, you must use those prefixes depending on the type of address you got on Bitcoin Core.

If Core's address starts with "1" type:   p2pkh:PRIVATEKEYHERE   as the private key when importing.
If it starts with "3" type:   p2wpkh-p2sh:PRIVATEKEYHERE   as the private key when importing.
If it starts with "bc1" type:   p2wpkh:PRIVATEKEYHERE   as the private key when importing.

It's obviosly the same the last poster said, but it's extremely important you do this as fast as possible, that's why I tried to explain it with other words.

However PLEASE, as nc50lc said, edit your post NOW to avoid getting your coins stolen. Google provably already cached this page, so it's just a matter of time that address is compromised and the funds it has now and in the future are lost.

The solution for this is integration with your address management system through a ZeroMQ instance, using the provided Bitcoin Core options:
This is part of the normal options you can use when running bitcoind or bitcoin-qt, available at https://en.bitcoin.it/wiki/Running_Bitcoin

Even if it's corrupt, you may be able to get some results using other methods.

Please note it's strongly recommended to backup your entire drive (or even working with a drive clone, if possible) before trying to recover the keys. A boot CD/USB is a great way to achieve this.

Then, here is a guide on how to use pywallet for searching keys: https://bitcointalk.org/index.php?topic=38004.0 (credits to LoyceV for listing it on his thread).

As a last resort, I repeat - as a last resort, and working with a backup: the -salvagewallet command may be able to recover some of the keys: https://en.bitcoin.it/wiki/Running_Bitcoin#Command-line_arguments

This video explains it much better than most lengthy text explanations, and pretty much non-technical:

Which commands are you using to unlock the wallet?

AFAIK, this should be what you would need to do in order to get the private key from <address> using passphrase <passphrase>:

• walletpassphrase <passphrase> 60
  (where 60 is the amount of seconds you want the wallet unlocked for. Remember to use 'single quotes' if your passphrase contains spaces or special characters)
• dumpprivkey <address>

Did you try removing the "gen=1" option?

Here is a list of nodes: https://api.blockchair.com/litecoin/nodes

It is/was actually unsafe and privacy-harming to use Google charts (and any other API for that matter) for generating QR codes on anything related to cryptocurrency.

You can generate QR codes browser-side with a Javascript library like https://davidshimjs.github.io/qrcodejs/

It's extremely easy to use. Make sure you self-host the .js file to avoid any potential attacks.

This is the fake mandatory upgrade attack other users are talking about: https://bitcointalk.org/index.php?topic=5090097.0

Can you try running bitcoin-qt with the -debug -printtoconsole options from a CMD?

Command line options reference: https://en.bitcoin.it/wiki/Running_Bitcoin

Have you checked if it's still running in the task manager?

Is there anything in the last logs at %APPDATA%\Bitcoin\debug.log?

Thanks a lot for your reply.

The plan is for them to be located on as many different locations as possible.

What is the bottleneck with the current version for the download? I'm asking because if it's the network, I can get a 10G server to download the data and use rsync later as you said (some locations have quite limited ports, and I think rsync will be faster in those cases).

I'm planning to setup around 20 full nodes, and in order to make the process as fast as possible I was looking for a way to speed the "bootstrap" process.

Last time I did this there was a torrent regularly updated I think, as well as a site with a public download.

That was quite a few years back - now I've found a few of them, but I'm unsure if any of them are maintained by the community / a trusted community member, as I'd obviously prefer to use a trusted data source.

To connect to a specific node, use this in the console:
(Make sure to replace 1.2.3.4 with the node address.)

You can also add the following line/s to your bitcoin.conf file:

I personally highly advice you to switch from E-mail TAN to Google Authenticator:

Source: https://www.bitcoin.de/en/faq/how-can-i-change-my-current-2factor-authentication-otp-method-password-table/181.html

I will repeat again: Google Authenticator. Do NOT use SMS authentication to protect your Bitcoins.

From my understanding, there should be no way to get the xprv (the xpub's equivalent private key) from your Trezor, so you would have to still authorize each transaction manually. This is because the private key never leaves your device.

You use the XPUB for that. It's available in the Trezor wallet by clicking on the device name > "Account public keys (XPUB)".

Be careful with those keys - while not allowing spends, they allow anyone to list all the public addresses in your wallet.

These two tools can be used to get all the addresses given a XPUB:

That's true - many people don't seem to get the difference between an EMI and a bank.

They want to launch a real bank.

Yes, you can register and place bets. There are quite a few fun casino games as well.

According to ingotcoin.io the IC Wallet is planned to be released on Q4 this year, and on Q2 2019 IC Digital Bank will start working.

Will the IC Digital Bank end up replacing the IC Wallet or remain as two separate entities?
