Check the state of the blockchain against an other HTTP API.

Great starting points:

Since the bitcoins can't be recovered without password, unlike other wallets, I think the warning message that bitcoins can't be recovered withtout passphrase should be at moment of entering the passphrase and not at the time of writing down seed.

• Json lib might works differently for Windows and Unix, therefore fingerprinting might be an issue.
• We need a proof that the RSA pubkey of the server is indeed a pair of an RSA privkey that can blind: NTumbleBit/NTumbleBit#72

MIT would be preferred.

Hi Adam,
I am having an issue on this line 51 on Program.cs:
Global.TorProcess = Process.Start(torProcessStartInfo);
I get the error that the system can not find the file. But that does not seem to be the issue, first off the tor is located in the directory specified. And secondly to verify, I pass the absolute path of tor.exe by modifying the line that points to tor.exe, but I still get the same error.
//torPath = @"tor\Tor\tor.exe";
torPath = @"C:\Users\Bijan\HiddenWallet\HiddenWallet\HiddenWallet.API\bin\dist\current - target\tor\Tor\tor.exe";

I suspect that this is caused by arguments on line 46 of program.cs
Arguments = "SOCKSPort 37121 ControlPort 37122 HashedControlPassword 16:0978DBAF70EEB5C46063F3F6FD8CBC7A86DF70D2206916C1E2AE29EAF6"

FYI: I have written a small console app and am able to launch tor.exe without any parameter using process.start().

Thanks - Bijan

This is an advanced user's wallet, so I don't see why careful users who know the risks of using clipboard wouldn't be allowed to (especially for test)

Is it possible to have multiple wallets?

Seems like we can only have one.

I started with Main, then switched configs to Test. I had to deleted the previous wallet, couldn't create a new one and couldn't decrypt old one. I haven't tested actually going back to Main after switching to test and see if old wallet still works.

If the user is 100% sure it didn't receive transaction while it was away, it can skip the syncing.

While SPV with bloom filters are generally bad for privacy, there is an other way.

Keep an eye on this Bitcoin Core PR: bitcoin/bitcoin#9076

Think about: other http api? directly to the network? Electrum's protocol?

Headers can be synced at that phase, no need wallet to be decrypted there.

It can silently sync in the background when the wallet is closed so won't be so long syncing times.

Not sure that the "Move coins between Alice and Bob only by mixing!" message means.

Also not sure why there are two wallets Alice and Bob? What are they for? What's the difference between the two? There seems to be only one wallet file.

Somehow, the mnemonic pop-up window disappeared before I could take it down. Doesn't seem like there is an option to get mnemonic. That's definitely a must if you have the PW.

For reference, NTumbleBit does it. https://github.com/NTumbleBit/NTumbleBit

Hi average user here my BTC is stuck in my wallet. Every time I try to send it say something about Tor refusal and I can't send coins. Now it no longer shows Alice or BoB wallet as well. I would be more than happy to give you my seed so you can send my coins back. I do understand this was use at your own risk as it is being developed. It was working fine and is now no longer.

Not sure what the "hide icon" does here:

I clicked it and it seemed like Hidden Wallet closed, I don't see it in windows task manager. However when I re-opened I didn't need the password to access wallet. Haven't tested if I can spend funds without password re-prompt yet though.

Just took a quick look at this post, if I'm right you can set in your project level if you want spaces or tabs. I like tabs.

I use NTumbleBitTest branch.
However, dotnet restore returns the following error on NTumbleBitTest branch. That command on master branch works well.

~/HiddenWallet/src/HiddenWallet$ dotnet restore
/home/hogehoge/HiddenWallet/src/HiddenWallet/HiddenWallet.xproj(8,3): error MSB4019: The imported project "/usr/share/dotnet/sdk/1.0.1/Microsoft/VisualStudio/v14.0/DotNet/Microsoft.DotNet.Props" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

I installed dotnet-dev-1.0.1 by apt-get on ubuntu 16.04 but what library do I need to install additionally?

After: CCJ Tumbler is built.
