Are you sure its extra input and not replacing the RNG data that is normally used?

samr7 indicated the following in the initial post:

That line seems to indicate its seeding entirely from the external file and not just using it as additional data.

Whoops. I was looking at an Electrum wallet.dat file which likely uses a different format.


That should be the correct method. Try checking the debug.log file which should generate some output on the results of the salvage wallet command.

How low was the fee? I recommend using dynamic fees in the future to help ensure adequate fees are used for transactions.

You may be able to help push the TX through by creating a new transaction with the change of the first transaction and including a high fee. This sometimes encourages miners to include your transaction so that they can claim the fee of the new transaction.

Assuming the .dat file isn't corrupted. You should be able to simpy open the .dat file in a texteditor or use cat to view the contents of the file. The private keys will be in this file listed under xprv . If the wallet is encrypted, you may need to unencrypt it first.

If the file looks to be corrupt, I would try the following.  Run bitcoin application with the -salvagewallet parameter via command line. This command attempts to salvage public/private keys and master encryption keys (if the wallet is encrypted) into a new wallet.dat .

Yeah, MultibitHD isn't an online wallet so all the processing is done on your local PC. As long as you have a copy of the application, you should be able to continue to use it even if the company stops development.

Also, with most online wallets, you can download a backup of your key files which can be used to recover your funds in a local application should the website stop working.

This option is used to tell VanityGen to use a seed from the file you specify instead of its default seed ( which is from OpenSSL or /dev/urandom on Linux ).

I don't recommend using this option as the default seed should be secure and random enough and if you use this option to use a seed from a static file, someone else with the same seed could generate the private keys for the addresses you create. This feature is likely designed for if you have a hardware RNG device that you wish to use as a seed which I doubt many people have.

You mean when using the new version of Bitcoin Core with your old wallet, you are also seeing the exception error?

First off, I would make a backup of your wallet file for safety purposes. It is possible your wallet file is corrupted and causing this error.

Then, I would try running bitcoin application with the -salvagewallet parameter via command line. This command attempts to salvage public/private keys and master encryption keys (if the wallet is encrypted) into a new wallet.dat

Yeah, that max win went up to over 200btc at one point xD . Thought it was a real investment at first but turned out not to be lol.

I wouldn't visit this link. It comes up with "The web page is on the list of websites with potentially dangerous content." so its flagged as being malicious for some reason.

And this forum really isn't the place to come for support for that site anyway.

You can try spending the change of the transaction with a high fee. This will sometimes cause the miners to include your original transaction when they try to include the newer transaction with the higher fee.

If your account was indeed compromised, they should be able to provide you with an IP that logged in as well as an address your funds were withdrawn to.

Is this information visible in your account or have you requested it from support if not?

The new version should be able to use your existing wallet file without an issue as far as I know. I'd be more concerned with getting the new wallet working with your wallet file if I were you. It should load your existing wallet by default I think. Was it not doing this?

What operating system are you using? Did you recently upgrade the OS or install any updates, etc?

If the new version works, I'm not sure there is really a need to get the old one working again to be honest.

I wonder what the requirements for an exchange to get insurance against hacking would be? I'm assuming they would require some sort of code audit in order to qualify? Seems like it would be pretty risky for insurance companies to ensure against hacking for these large exchanges.

Trezor 2 hasn't been released yet and is still in production. As far as I know, they haven't posted any ETAs or release dates yet.

I've been debating getting a hardware wallet but might hold off to see when Trezor2 gets released.

One would expect the wins/losses to even out over a significant amount of time, but this easily leads to Gambler's Fallacy ( https://en.wikipedia.org/wiki/Gambler's_fallacy ). There is really isn't a higher chance of more winners in the next 100 bets. It's all up to chance on what will happen.

Version 3 of BitDice had blackjack and it was just player vs. AI (provably fair of course). I don't forsee player versus player or multiplayer features being included.

Yep, BlackJack is definitely a fun game to have. It gives you more of a feel over the impact of the result as you can choose whether to hit/stay/etc.

Yep, they have NFL games on the 14th/15th that you can wager on. This looks like a pretty fun promo. I'll try my luck and see if I can manage to hit a 4-leg promo.

Yeah, I've heard good things about Breadwallet for IOS as well. Whenever Electrum finally releases its IOS version, I'm thinking it will be the goto choice for IOS if it is anywhere near the quality of their desktop version.
