Trying to generate the vanity address on MacBookPro9,2 fails when trying to use integrated Intel HD 4000 GPU. Works fine with CPU, it's just very slow when it comes to more than four character long addresses

I'm one of Bither's developers. I can't generate vanity address with the integrated GPU on my Macbook either. After some digging, it turns out that there are some bugs in Apple's OpenCL driver. Unless Apple fixes this problem, we won't be able to use our integrated GPU for OpenCL computation. We'll continue digging into this. Thank you for trying our wallet.

In this software for making custom bitcoin addresses are their any areas to doctor settings to improve speeds for using gpu and over clocking etc than basic default setting.?

Currently Bither just uses Vanitygen to generate vanity addresses. GPU acceleration is supported. But over clocking is not a thing on the software side, it may be done by the user using some other system utils.

We are planning to keep improving the Vanitygen project. In the future versions of Bither, there may be more optimization.

Are the calculations vanitygen has to perform of the same kind as bitcoin mining? Could somehow a hardware miner be used to accelerate those calculations?

They are, for the most part, very different.

Miners (partially) calculate a double SHA-256 hash of some input.

Vanitygen is based around a bunch of much slower elliptic curve based math (plus also requiring an SHA-256 calculation, which takes relative little time).

Mining ASICs would unfortunately not be useful.

Maybe some FPGA miner can help us accelerate the calculation.

It won't help too. We can use ASIC and/or FPGA if someone finds a software to convert this power which I wonder "how" and "when". If they found it, uses of ASIC and/or FPGA will increase in a great way.

An FPGA miner wouldn't help - but yes, programming an FGPA with the necessary functions would.. but it would mostly help in energy efficiency.  Any modern GPU blows reasonably-priced FPGAs out of the water in terms of performance.

Bither v1.3.4 released.

What do you mean by "rotate" and when will Bither support signing transaction with more than one output?

Thanks for the updates. Look forward to the updates and improvements in the future. Before couldn't use my gpus to mine addresses with due to my cards using this software I am able to generate with GPU but slow. Still least I can now generate than before I couldn't. Looking forward to future updates.

I'm wondering if reprogramming some used FPGA miner to generate vanity addresses will be possible.

HD account will use a new address every time you want to receive a payment or send a transaction with change.

We are considering maybe supporting multiple outputs transaction in some kind of a plugin.

Thank you for your supporting Bither.

We can still choose an address in our wallet to send change like we do now, right?

Didn't get the plugin part. Anyway, ETA?

IMHO a "+" button for adding output addresses is better. See brainwallet.github.io/#tx or 'Blockchain.info custom send' pages.

>Bither v1.3.4 released.

Is the HDM Server down at the moment?  I've setup my Cold Wallet and linked it to my Hot Wallet across two devices (both iOS) but on the Hot Wallet device the HDM Server does not respond to any taps.  

In the Youtube video I found it shows this as a bright circle, on my phone it shows as dull.  Is this signifying it can't reach it or am I doing something wrong?

Thanks!
BK.

I'm wondering if reprogramming some used FPGA miner to generate vanity addresses will be possible.

As long as they didn't lock out programming on the FPGA, sure.  That applies to any FPGA product, though - and at this point unless you're getting a sweet deal on an old FPGA miner, you'd be better off getting a dev kit from one of the big FPGA companies or their partners.

Before couldn't use my gpus to mine addresses with due to my cards using this software I am able to generate with GPU but slow. Still least I can now generate than before I couldn't.

I strongly suspect that's down to the command line used, then - the vanitygen binaries in the bither package (Windows anyway) are stock Vanitygen 0.22.  Might want to try figuring out what command line it uses, then feed that manually to vanitygen and try changing parameters around from there.

When using addresses other than HD account, we can still send changes in the old way.

Didn't get the plugin part. Anyway, ETA?

We're planning to do this in the next few versions. No ETA yet. It's a good advice to add a "+" button. Thank you for your advice.

Is your hot HDM account already set up? In anther word, is the triangle completed? If your hot HDM account is already set up, the HDM server button should not respond to any taps. If not, please let us know. Thank you for your feedback.
