[ANN] Bither - simple&secure Bitcoin wallet.(iOS/Android 2.0.2)

[bithernet]

Bug:

• I install Bither, choose "Cold", generate 6 privkeys and make backup
• I de-install
• I re-install and choose cold again
• Now I have immediately 10 (not 6) priv keys: The 6 from the backup, plus 4 new ones. Where do the 4 new come from? -> bug

Yes, it's a bug. Thanks for reporting.
We will fix it in Bither Android v0.0.9. https://github.com/bither/bither-android/issues/9

 

P.S. : The backup of Bither Cold is ok and safe, and this bug is in the reading backup file part of the code (when newly install the Bither Cold).

Bug:

• I install Bither, choose "Cold", generate 6 privkeys and make backup
• I de-install
• I re-install and choose HOT this time
• There is no way I can restore the privkeys from my previous backup -> bug

Because the SD card on Android are shared between Apps, we only support backup private keys to SD card on Bither Cold.
That means Bither Hot will never backup to SD card or restore from SD card. The only way to restore Cold private keys to Hot Wallet is to import private key one by one using advanced options. We suggest users keeping Cold private keys as cold as possible, and using Hot private keys as simple as they can.

We may improve this design in the future.

Thanks again for your help. It's very nice of you.

Only compress private keys are supported? Can you make the wallet support other formats too?

P.S. There is no address book. Can you implement that too? Thanks!

Thanks! AND, why doesn't it import private keys while the phone is offline? Can you fix that too? I will try to keep my feedback up-to date.

When importing private key, Bither hot wallet need to sync the old transactions of this address, so it need to be online.
Currently we are working hard on Bither v1.1.0. After we finish releasing the new version, we will try to improve this.

I understand that. But what I meant is, just import the private key even when the phone is offline and the sync when it is connected. There comes situations to import private key when the phone is offline. It would be helpful if a 'successful' message or something like that shows if the import was successful. How many mBTC is spent when default transaction fee is set to 'high' and 'low'? It would be better to show the amount below the words(high & low) in settings. How about making an option to sign and verify messages? It would be great! A QR-code for the signature would be good too. You can make that a bit more good by making a short line above the signature on top-left saying something like : QR-code 'right arrow', i.e., when the user slides the signature to left, the QR-code appears from right side.

Good going! Are you using any other servers for transaction? Like Blockchain.info API?

Bither has a nice looking ui, and their android version looks like it's using bitcoinj, so it's a real bitcoin client using SPV, however I checked the code and the iOS version is a "server trusting wallet". It trusts a server for your balance and transactions so if the server gets hacked or goes down, you loose access to you money.

Good going! When will the next update for iOS coming?

Bither is a decentralized SPV mobile wallet based on Bitcoin P2P network, and we do not use blockchain.info API.
Bither iOS are just like Android version, are implemented with our own developped Objective-C library Bitheri, and it is decentralized too.
The server is only used for Exchanges' rate and k-line, and also history trxs when monitoring. So if the server goes down, you can still use your money or check balance, and receiving new transaction.

Bither iOS v1.1.0 will come soon after a week, maybe plus another week for Apple's reviewing time.

Thanks for your support.

Thanks! I think the wallet got some attention from users. I think you have saved 1mBTC . So how many days will apple's review take? I think for Bitcoin, it will take a bit more. Have you published for reviewing or are you going to publish? Sorry didn't look carefully!

[Muhammed Zakir]

I think a new problem has been arisen. So have you done that? Did you forgot about the license agreement? OR is voisine wrong?

What do you mean by "Bither is a server trusting wallet"? Please check carefully and please don't spread false news!

You are correct. My apologies. I mistook the code that connects to the bither server api for the code that handles transaction and balance data. The bitheri library appears to have copied large portions from the breadwallet source, and is in violation of the MIT copyright license I published it under. I've submitted a github issue requesting they retain my copyright notice in compliance with the terms of the MIT license.

I especially like the cold wallet feature.

Good job!
