Where are the devs for this wallet. Seems active one min, next inactive or not around much.

Would like to put another idea forward for layout and improvement for usability.

Sorting feature for Addresses

This you can create folders and drop your addresses into each one to sort out for different types of nature. Each folder can create a name for it then add the address into it.
Gambling, Business use, Personal use, Donation and so on making own separate folders.

Just a small idea I know some would like and would like this sort of feature in it to sort all addresses into different categories, that way I know where stuff is and what is used for what Smiley

Sorry for the late response. We are living in China. The government puts a strict limit on the networks. We'll have to use some kind of a proxy to visit bitcointalk.org. That's why we are not responding in time. Sorry.

It's a good advice that you brought to us. We will discuss it. Thank you for your support.

bither sdoes not work on osx yosemite!!!!

i had so much money inside when I used mavericks...and now after upgrading all money has disappeared!!!

latest version does not work on mac os which was released a year ago!!!  and you guys are busy with apple watch?

fix this or tell me how to get my money out of that app, where is the wallet folder and how do i get all money out of it???


please help asap, thanks!

Eh, Bither is meant to be working right on Yosemite. We all use Yosemite in the team. How did you upgrade from Mavericks? Did you erase all your data? Bither's data is stored in this folder ~/Library/Application Support/Bither . You can go and check if your data is still there.

seems like you are right...i have seen now that my last block was 2days ago which was sync by my wallet...as you can see here http://imgur.com/3Cx1K0z
i will try to sync todays whole night and tomorrow i will posts whatever the results are... thank you for helping Smiley

Thank you for trying to use Bither as your wallet. I'm one of the developers. I can see you are already on the right track. If you have any further questions, feel free to ask me. We will try to increase the sync speed in the next version.

What is 'Reset HDM Server Authentication' for?

The hot wallet needs to store an encrypted token authenticated via BitID by the cold to the HDM server to ask the server to cosign.

'Reset HDM Server Authentication' will ask cold wallet to authenticate a new token, and revoke the old one.

Usually you don't need to manually use this function. This is only useful when you try to use your hot wallet to send transactions if you has tried the recovery of your HDM account and yet you still have your original hot wallet in your hand. The recovery will revoke the token on the original hot wallet. Therefore the hot wallet needs a reset of the authentication.

>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.


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.

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

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


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.

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.

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.

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.

Thank you for your supporting Bither.

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

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.

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.

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

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.

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 Smiley

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.

1. Using the same Cold HDM for multiple HDM setups is not allowed, causing the error.
         - There should be an error message explaining that this is not allowed.

Yeah, you are right. We should make this error message clearer.


The iOS xRandom process is insanely short.

On Android It takes about a minute (could be my Android is slow) to grab all the entropy...

iOS takes less than a second. The animation of xRandom opens, then shows the camera and transparent icons, then closes almost immediately. I am worried my Hot HDM is weak.

My specs:

iPhone 5
iOS 8.1.3

I gave all permissions to Bither when it asked for them. (right before running xRandom first time)

I've run some tests upon this and checked the code. It comes out that the BIP39 calculation speed is what differs between iOS & Android. My iPhone5s does this nearly 10 times faster than my middle end Android phone. You have no need to worry about your entropy.

Thank you for using Bither and giving advices.

1. "Easy to backup (only need HDM Cold seed)" does this mean the Server key and the Hot key are derived from the cold key? (as if it wasn't, I would assume you'd also need the xpub from the server key and the xprv from the hot key to generate the addresses and sign for 2 of them.)


Each HDM seed is generated separately on its own device. Server key and the Hot key are NOT derived from the Cold key. The Cold key is used for HDM Server's BitID access control. In this way, if you lose your hot phone, you can use your cold phone and server to recover bitcoins, and if Bither server is down, you can use your hot and cold phone to recover bitcoins. Generally, you only need to backup the cold seed.



2. Will the user be able to scan / input their own xprv/BIP39 phrases as their key(s)? (In case I want to generate my own entropy) How would that process work?


Currently we do not support importing seeds, because importing will make the HDM account generating process too complicated, we haven't found an elegant way to do this. We only support recover cold seed from backup at this point.

Re: Who is the owner of these Bitcoin nodes (46.105.210.*)?
by

They don't respond to ping either. I dropped them from Bitnodes crawler (https://github.com/ayeowch/bitnodes/blob/master/crawl.conf#L46) as they don't seem to be contributing to the network. The nodes are hosted by OVH and they give you free /24 IP block when you subscribe with them. So, it is likely that the nodes from 46.105.210.* are operated by the same owner.

One free VPS does not seem to have the enough space to run a Bitcoin full node. I think he is doing some other kind of work but appears as full nodes on the Bitcoin networks.

Have you tried to send tx with non-dust amount and reasonable fee only to these nodes?
Was it mined in reasonable time?

Yes, my tx is standard. And when I send it to other nodes, it gets confirmed soon.


Bitcoin network traffic sniffing & analyzing. Usually, there is more than enough to have one node for such work.
Wondering why do they have several IP addresses.

I'm wondering too.

These nodes with IP address 46.105.210.* suddenly came out from nowhere.

These nodes all seem normal. They have the latest blocks and the version code 0.9.3. You can ask blocks from them. But you can not send transactions through them. When you send Tx hash to them, they never come back to you for the Tx detail.

Is there any thing special that nodes like these are made for?

Re: [BIP][Draft] Transaction Signing via QR Codes
by
songchenwen
on 18/09/2014, 03:10:53 UTC
This simple idea is obviously not new but no one tries to implement it. It is because the "COLD" cannot calculate the transaction fee without first knowing the full details of the inputs. You will need lots of qr codes to do this.

If you omit this, a malicious or buggy "HOT" could trick the "COLD" to pay a huge amount of transaction fee.

Learn more: https://github.com/bitcoin/bips/blob/master/bip-0010.mediawiki

1. Modern operating systems on mobile phones like iOS and Android run apps in sandboxes. One app can hardly become malicious if the user has not rooted or jailbroke his device.

2. The hacker who do his best effort to get control over HOT can not benefit directly from his work. He can only give the miners more bitcoins but leave no extra income for himself.

Hi. Onchain.io has support for signing transactions via QR codes.

You can see the code and some screenshots of the app here. https://github.com/onchain/onchain-android

It would be good if the BIP followed the existing protocol.

Let me know what you think.

Bither was made half a year before.

So when you mention existing protocol, we should consider Bither's.
