New iOS wallet called Bither supporting both online and offline use

[BitcoinMachine]

A few days ago when I searching the App Store for a bitcoin wallet, I found Bither. It's just like the kind of wallet I've been waiting for. So I became excited, installed and tried it.

Bither has two modes, "hot wallet" and "cold wallet". You need to install Bither on two devices and both Android and iOS versions are available. The cold mode can't not run when the device is connected to the internet. Typically, you keep the hot wallet on your daily phone and the cold wallet on a backup device. I tried the cold wallet on my 3 years old Android phone, and the hot wallet on my iPhone 5s.

Hot wallet can monitor addresses generated on the cold wallet. You can spend your bitcoin from monitored addresses with the hot wallet. The hot wallet makes an unsigned transaction QR code which you can scan with your cold wallet. Then you sign it on your cold wallet which in turn makes a signed transaction QR code. After you scan it with your hot wallet, the transaction is sent to the network.

Even though the concept is a little complicated, it works well. And it seems really safe. I think Bither has found the balance between safety and convenience in keeping bitcoin. I can't see any easier solution as safe as this so far.

As I said, I'm excited about it.

And I found a demo video about it.

Looks OK, and I like the concept of combining cold storage to secure large sums of money with a hot wallet for daily spending.

However, considering the fact that it's closed source and from a fairly unknown developer, I would not trust my money with this. Especially with large savings, I will only trust that to something I can either 100% understand and verify myself, or that the general public (and in particular, other independent developers worldwide) can understand and verify.

I hope the developer will make this open source, as I think it's definitely a step forward in term of usability, and finding a compromise between ease of use and strong security.

Thanks for your interesting in our project.
We already opened android version's source code on github : https://github.com/bither/bither-android
Currently we are working hard on Bither iOS v1.0.1, and we will commit the source code ASAP : https://github.com/bither/bither-ios

I saw their android version source code. As they said, their iOS version source code will be open soon. I think we'll just need to wait a little longer then.

We already opened android version's source code on github : https://github.com/bither/bither-android

Awesome!
I will install bither on both Android an iPhone, and check it out. I like to have multiple wallets on each device and play around with them.

Great work man!

Thanks again. After we commit the source code (iOS) on github, we will update the project topic (in next week).
Also we sugguest Bither users to use Android phone as Cold Wallet (iPhone for Hot Wallet), because there are lots of  cheap android phones (even < $30) and many android phones support SD Card. That means you can have extra backup device of your private keys (Bither Cold will automatically backup the encrypted private keys on SD Card).

You should try Bither with small amount of bitcoins first (e.g. several mBTCs). After you are more familiar with Bither, you can try a little more on the Cold Wallet.

Special notice: Never uninstall the Bither App, unless there are safe backups. The mobile OS (iOS, android) are not like the desktop system (Windows), uninstall will remove all App's data.

So you should hurry to commit your source code. I'm watching.

I would say this is a pretty nice development in the world of bitcoin. 

I have always wanted to put my bitcoin into cold storage but felt bothered with installing Linux, then a wallet, then making sure that computer was always offline. 

If I could just download an old app to my old phone and then use my current phone to sign it, that would be pretty awesome.

good stuff. I've always been surprised that there are not more crypto wallets in existence with the jailbreak community.

Well done. This looks really promising.

Wish they have an android version of this. It is much easier to spare a cheap android as your 'cold wallet'

This sounds amazing, but this is me trying to understand how it works.... https://p.gr-assets.com/540x540/fit/hostedimages/1380397958/768540.gif

This is an exciting BTC Wallet. Also, you can use android version. Android devices can backup private key to SD card automatically. For IOS devices, you'd better backup your private keys with QR code manually.

Android version is also available in Google Play https://play.google.com/store/apps/details?id=net.bither
