Hey guys.
Coinomi accepted my pull request so we will be making it into their mobile wallet for the next release. If you aren't happy with the current Android wallets than I suggest taking a look at what the coinomi team is doing.

Two consecutive transactions over the same public address leads to a pattern relaying on the elliptic curve cryptography method.
So working along with reverse engineering, hacker can find the private keys, where he can extract them and steal coins whenever they want to.
Imagine if those private keys belong to a cold wallet of huge bitcoin exchange... It can be a disaster for digital currencies...
This has been always the problem in the history of cryptography, and it is actually the reason why cryptography has born.
Let only the target person know what your information is, but don't let anybody else know about it.
So you have to encrypt it at the source, but also have to allow it to be fully recoverable at the destination, without getting caught in the air with some patterns.
To be honest, it is not an easy job, requires a lot of focus and luck. If someone can do it, I am sure they deserve it, but need a patch ASAP, maybe adding another layer of security of some hashing algorithm for the public address and its transaction IDs could be a solution, to remove the patterns...

Second link TLDR: if you create a bitcoin trojan, you can steal bitcoins. Excerpt: "The attacker must first create a compromised version of ECDSA". Nothing worth fretting over.
900+ words, and I recommend reading them all.
My favorite excerpt:
Quote
Both Verbücheln and Pustogarov say that the most likely way for such an attack to be mounted would be through dedicated wallet services running proprietary software. Devices designed specifically for secure cold-storage of coins, for example, would be prime candidates for this sort of attack.
Stealing your digital currency right off the blockchain - they don't even need to get to your computer, much less your wallet!
I wasn't planning to respond, but since you reposted the link let me give my breakdown of the article.
To exploit this vulnerability, the attackers must first create a vulnerability to exploit. That is, they have to get malicious code into the bitcoin source code, or otherwise get their intended victim to download compromised wallet software. If they successfully manage that, then they can steal bitcoins from an air-gapped wallet running their compromised code. But if they could insert malicious code into bitcoin in the first place, compromising air-gapped wallets would be the least of everyone's troubles.
I have perhaps the mistaken idea that the attacker only has to create his/her own compromised ECDSA wallet with which to transact with other legitimate wallets that are completely unaware of the exploit since the k2 value sent by the attacker is seen as being a legitimate k value.
The attacker then “watches” everything it transacts with in the hopes of paring up two CONSECUTIVE transactions from the same address.
The attacker's objectives are met once two consecutive transactions are made with the same address, and the victim’s private key is “leaked”, or, as I would say, stolen (after working backwards to calculate k and the private keys to that address).
We need go no further than pool mining to find an ideal place to transact with multiple addresses in consecutive fashion . . .
Correct me if I’m wrong. I’m the first to admit that this is a complicated matter.

On a slightly different note, interesting price action in DGB. Very technical, which is good. Looking forward to seeing what happens now.

Jared, maybe something to think about for future updates:
If I tip someone who doesn't have an account at DigiByteTip, is it possible to reserve the coins for that person in case he decides to create an account? (due to my tip
).
I really want to start tipping people on Facebook when you implement FB-tipping, but my friends aren't really crypto-minded... yet.
Although i'm constantly bragging about the stuff i buy with my profits

Yesterday i did get a update for my samsung s5 regarding a new version.Android version 5.0
I haven't been able to test the wallet with lollipop yet (Android 5.0) but I don't imagine this would cause any issues.
How close is facebook tipbot?

And who, by the way, is this kid Jared Tate, I mean what are his qualifications? I understand that for a kid his age attending a session of CNBC at the Nasdaq is a big event but, really.
https://www.linkedin.com/pub/jared-tate/90/9aa/257
BitcoinTate-Well respected KID in the bitcoin world.
https://bitcointalksearch.org/user/bitcointate-83404
And who are you?Would you mind to tell everybody on the internet your name and everything you can find with that?
As Jared told before,The team is not ready to fully give the information YOU want because there are everyday hack and phising attempts to the personall account of Jared and to the Digibyte network,Website etc. etc.
And just a thing i want to say,Offcourse a discussion and questions are good and healty but does is need so much negative thoughts in it?
Well I'll tell you, I would absolutely LOVE to find ANY positive in this thing. I haven't succeeded at it at all, hard as I have tried.
Now, regarding who am I, IF I were someone who would come here to offer a project or expect to get your or anyone's sponsorship for my project, I would consider a condition to not only reveal who I am but offer every other assurance of transparency and accountability possible, the more the better. Kind of the cleanest restaurant possible if someone would want to enter the restaurant business? You don't need to know the identity of your customers, unless required by law... as long as they PAY for whatever you sell, right? As it stands, I am not a developer and I dont need, seek, or want anyone's sponsorship... just the opposite of the dev "teams" all around in crypto.
But to put an even closer example that I am sure you would understand clearly, all these projects are quite similar to any other enterprise that, ONLY AFTER VERY MEETING VERY CONSIDERABLE BARRIERS OF IDENTITY AND TRANSPARENCY, among others, is offered in any international stock exchange. By LAW, they are required not just to meet those requirements but also to offer clear accountability for their expenses every 3 months. Publicly. And audited.
But those, you will be right to say, are SERIOUS business while these alas...
Do you have a DGB address? I would like to tip you for the most sincere display of trollery I've seen in a good while.
Of all the coins to be picking on, man. Seriously. Let me do you a favor and send you some DGB to hold on to long term.
If you don't mind much, I would pass on your otherwise wonderful display of generosity... unless we are talking some serious figure, of course, which I sincerely doubt. I know I am probably saying no to future millions of BTC but, like I said, I am strange that way (to better effect, read this loudly and trying to imitate Chris Walken).
Man, you are a good group!
No matter how rude someone is you try to help anyway.
Judging by some other posts this person made, there's an ulterior motive.

This is again just a proof of how many people want to buy in Digibyte cheap
Not yet. I could kick my ass that i tried to stabilize @ 70. ill aim for 35 now. not one cent i invest at this level!
Haha i don't hope you right but time will tell
on the other hand more btc is coming already in the 54 ranch 
Not much resistance there till 42-40 maybe. I think we will see the 48 already this night. The autosellers pressure is pretty high.

My best guess at what a cheap DigiByte is in the current crypto market before mass adoption by the general public is....
anything under 0.00000282 BTC, so right now they are really cheap!
Estimate made on a direct comparison with Doge, this is not financial advice, just an observation about a crypto currency growing in popularity with a dedicated and honest development team behind it when supported by a solid community!
Steady digibyters, Hold. Do not sell until you can see the whites in the buyers eyes!

don't get left behind
I'm kicking myself that I was too busy with work to buy a few more million when it was 12/13. If I'd remembered when I was home I def would have. Live & learn...
