Thats just laziness.

You haven't replied on this, yet?

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.

Sorry for the late reply. It is holiday in China from Oct.1st to Oct.7th. Other members of our team are still on vacation now. I came back earlier, so I saw your PR and merged it.

In the past, we were working hard on improving our solution. We just used script to add license infomation automatically, and we had planned to add these after we released the stable version.

We will maintain all related copyright notices in the future ASAP.

Bither iOS v1.1.0 released on App Store.

I didn't quite understand what is XRANDOM? Is there a guide? With the new update more types of private keys are supported.

• Can the private keys be imported offline now?
• Is the license related issues fixed?
• Why is it only supporting 10 addresses/wallet? If you can't change that option(10 addresses/wallet), atleast make an option to delete addresses or archive it.
• Please provide value of BTC for all currencies
• Please implement an option to sign transaction from a paper wallet and to push it, after that all details will be deleted. You can check Mycelium github repo for source code.
• Does watch only supports addresses other than the addresses in Bither cold?

Thanks!

Dear MZ,
XRANDOM is a TRNG (True Random Number Generator) solution provided by Bither. When generating a new private key, XRANDOM will gather entropy from different kinds of sensors of your mobile phone (e.g. : camera, microphone, gravity sensor......), these will give user true randomness. After gathering enough entropy, Bither will combine the result with Kernel's SecureRandom (e.g. : /dev/urandom on linux) and return final random number.
XRANDOM has these advantages :
1. True Randomness;
2. even one of the two random source fail, the final result is still safe;
3. cheap (you donot need to buy hardware random number generator);
4. simple.

If you want to import private keys offline, you can import to the Bither Cold Wallet, and use the Hot Wallet to monitor the newly imported addresses.
We had added license in related files.
Bither Hot Wallet support 10 "hot" addresses and monitoring 100 "cold" addresses. We set these limits cause of the performance consideration on mobile platform. Because the new version (Bither v1.1.1) will improve a lot in battery usage and network data usage, we may upgrade these limits in future ASAP.
We may try to support addresses managements (delete/archive) in a safe way.
We will add more currencies in the future version.
Thanks for your advice on paper wallet, we will think through it.
Currently, the watch-only mode only supports Bither Cold Wallet's address, because of the SPV mode and decentralized. For a central service, it's easy to implement watch-only on any addresses, because all data are on their server.

Thanks again for your advices, all these advices will help our team a lot.

Thanks for explaining! But if we once choos hot wallet, we can't change it into cold wallet, right? So without another phone, I can't make a cold wallet address. Why I asked about deleting/archiving is because I generated 10 hot addresses when I found that we can't generate more than that, so I just want to make it sure, but now it is impossible to undo it unless you add the feature. I will try to import private key, somehow it might work. And, please show the a progress bar like for syncing because my address has received some BTC though it isn't received in wallet. So it will be good if we know how mouch time is left to sync and also you haven't added the value of 'low' & 'high' fees, please add that too. Thanks!

We will improve these functions ASAP. Really thanks for your advices

Bither Android v1.1.1 released.
1. Less battery usage; 2. Less network data usage; 3. Pure Java Bitherj;

[Muhammed Zakir]

Please add these too!

• Encryption of whole wallet not individual features like now.
• An option to see the private key of individual address and an option to back up private key
• If you are enabling #2 , force the users to enter password to protect it and you may want to enable file sharing through itunes.
• An option to scan 'n' number of private keys in a row. You can make a drop-down list for this like the drop-down list shown when generating address(es).
• Showing the full TX list of an address not from the time when addresses was imported or atleast the number of TX shown after the sign must be correct.
• An option to explore a TX in BE from the transaction list shown, just like exploring the address in BE from the wallet.
• Supporting other Block Explorer(BE) too, mainly, btc.blockr.io and blocktrail.com , these are the ones which is widely used.
• An address book. It would be good if we can add details other than name and BTC address in it such as email, phone number.
• An option to label address
• Option to reload the transaction data of specific address(es)

I think we need to chat through Skype or something!

Great! Chinese? Other languages are also supported, right? It would be better if we can print just the qrcode, private key and address and above a Bither logo and link(like armory does).
