221  Alternate cryptocurrencies / Altcoin Discussion / Re: MuCoWa - A MultiCoinWallet to your service - Update now: 1.3.0 Quark added on: March 07, 2014, 09:54:08 PM
I am wondering how this project added Quark to their software.  Quark has several differences (hash and precision) that would make more difficult to fork from bitcoinj.  Nevertheless, it can be done because I did it (https://github.com/HashEngineering/quarkcoinj).  A native version of the hash function for proof of work was also developed which was a definite plus for mobile devices.
222  Alternate cryptocurrencies / Altcoin Discussion / Re: Kimoto Gravity Well simplier alternative on: March 07, 2014, 07:45:45 PM
The KimotoGravityWell is an interesting algorithm to be sure and it appears to be the most complicated difficulty adjustment algorithm out there.  It is also the slowest.  This doesn't matter on a desktop machine perhaps, but on Android devices it really drains the battery.  Part of that has do with with the parameters (Megacoin can go back over as many as the past 4032 blocks).  Calculating the difficulty on an android phone can take as much as 1 second for a block.  Other coins that use the KGW are using different parameters so that they do not review as many of the previous blocks.

Would this proposed algorithm be any more efficient?  The KGW uses block solving times to determine when to stop going back in the block chain, but the next difficulty calculations are based on the difficulties of the previous blocks (all calculated with 256 bit integers).  This has to be much slower than a weighted average of block times (which could be 32 or 64 bit - something that most processors can do on their own without using a slower BIGNUM library).

I have replaced the Chinese Bitcoin for Quark.  Working on the splash screen and app appearance.  A new beta version can be released soon.
224  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) [w/ native hash!] on: March 05, 2014, 03:57:52 PM
Any idea when the finished version comes out?

The Quark wallet should be finished in the next few weeks.

Some translations such as Chinese will still say Bitcoin.
Hmmm..is there anyway for this to get corrected?

The translation of Bitcoin in chinese is known (比特币).  What is the translation for Quark?  That is what we need to fix it.
225  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) [w/ native hash!] on: March 05, 2014, 01:14:15 AM
You could look up the receiving wallet address http://qrk.blockr.io/ and then scan with the phone app. No?

Yes, this is possible.  However, it is not as simple as I would like it to be with the desktop client.
226  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) [w/ native hash!] on: March 05, 2014, 12:34:31 AM

Excellent, yes!!!! Thank you for this key tidbit Promethium-priceless! Grin Grin

These comments remind me that we need a wallet tutorial(of course a video would also be a dream come true)-

Can I get some contributors to this (submit here, or in a p.m. and I will post  a new thread on use of the Mobile Wallet (and also include it in the website I am in the process of creating).

P.S. We should have a scan QR code function on the wallet, now that we have the scanning capability.



One thing that would help is for the Quark desktop client to have QR code support added.  The Bitcoin and Litecoin desktop wallets have this feature as well as many other coins.  The feature is part of the source code that Quark most likely has already.  It needs to be activated when compiled and it will be available.
227  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) on: March 05, 2014, 12:32:15 AM
Is this app available in multi-languages? Or is the phone itself doing the translating?

The app is available in multiple languages because Andreas Schildbach has the Bitcoin-Wallet text translated to many languages.  In the Quark Wallet, all references to Bitcoin and BTC were replaced with Quark and QRK.  Some translations such as Chinese will still say Bitcoin.

The Kimoto Gravity Well has been optimized (from Java to a Java/C++ hybrid) and now runs up to twice as fast.

It will be released in Megacoin and Franko soon.
229  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) [w/ native hash!] on: March 01, 2014, 06:43:56 PM
Hashengineer and Coinmama,
Thank you so much for the clarification of the desktop wallet. I was so relieved that my coins were not lost last week Smiley

I have downloaded the newest version of the app.
For me there are no differences compared to the earlier versions. (I don't see any difference with the blockexplorer or something as mentioned above, that is probably too technical for me Tongue)

- The feature with the exchange sites is still not working with my app.
- Probably it is me, but I try to request QRK from my own desktop wallet, but I have no idea how I can do that? I can only type a requested amount but no address? The only address I can select is my own app wallet address. I probably do something wrong here, and I need some extra explanation how to do that.

I showed the app to some friends and family, so they get an idea what QRK is. Hopefully it will be in the playstore soon, so that they can download the wallet as well and I can send them some QRK.

In the desktop wallet, there is not an easy way to request quarks from someone else, other can copy and paste an address into an email.  The Quark desktop wallet does not have a "Show QR code" function.  If it did, one could scan that code with a phone app and send coins over.

I am not sure why the exchange rates are not working, let me see if I can find a bug.

New update to the Beta:

Changes Block Explorer to Blockr.io.  Also adds one peer.

https://github.com/HashEngineering/quarkcoin-wallet/releases/download/v0.1.5-beta/quark-wallet-0.1.5-beta.apk

This app will be available on Google Play soon.
231  Alternate cryptocurrencies / Marketplace (Altcoins) / Re: HashEngineering - Android Wallet Creation Service on: February 26, 2014, 11:13:18 PM
How difficult to add support  Scrypt-jane and Scrypt-Adaptive-Nfactor?

We don't have the answer for this right now as we haven't worked with these algorithms.  Native support will be key.  These hash functions really wear down the batteries of android devices.
232  Alternate cryptocurrencies / Marketplace (Altcoins) / Re: HashEngineering - Android Wallet Creation Service on: February 26, 2014, 11:12:06 PM
How do we begin the process of having you guys make a TrollCoin Android Wallet?
Thanks!
You can post a question in our forum and hopefully a developer will take on the job.  Currently I am too busy to take on more work.

233  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) [w/ native hash!] on: February 25, 2014, 07:07:10 AM
What is the preferred block explorer?

blockr.io?
quarkexplorer.com? - this one does not seem to properly display nicely on mobile devices.
another?
234  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) [w/ native hash!] on: February 24, 2014, 07:41:04 AM
I downloaded the new version its fixed a lot of the little bugs I had .

But I'm on an old version of android 4.0.1

When I went to restore the keys it force closed a few times trying to reset the BC .

But everything is sweet now , my balance shows as Quark not mQrk now.

When restoring keys, the app will reset the Blockchain.  This app should be compatible with Android 2.3.3 and above.

Google Play is coming soon, perhaps 1 to 2 days.

Hash, I saw this on the official QRK thread, hope it helps?:
I setup a node in the following IP:
87.220.174.144


Thanks for this peer.  I am trying it out now.

Hi! I love the work that has been done for the mobile wallet, but there is something odd about my wallet. It says that I have 88qrk, but if I try to send it anywhere, it says that my mobile wallet is "missing" those quarks. Then it says that (QRK 88.91 waiting for confirmation), even though the coins were sent a week ago. Is there any way I could get a real hold of these coins? thanks.

This sounds like you have a transaction stuck.  It will be necessary to reset your blockchain by going to the Menu and then Settings, then Reset Blockchain.  This may take 1 hour or less, but once the app syncs the blockchain, it will realize that the app never sent those coins and will give them back to you to send again.  This probably happened to you due to a network connectivity problem.  Try sending using the latest version of the app in the OP of this topic.
237  Alternate cryptocurrencies / Altcoin Discussion / Re: Quark Android Wallet Beta Testing (from HashEngineering) [w/ native hash!] on: February 23, 2014, 11:37:53 PM
Last week (16FEB) I send 0.7 QRK to my Android Wallet.
When I look to the block explorer it indicates the following:

Send 999.9 QRK

When I click on the 999.9 QRK, it indicates that 0.7 QRK is send to my android wallet and 999.2 QRK to the following address: Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX

That address is unknown for me.

According to the block explorer there is 999.2 QRK less in my wallet, than according to the paper wallet.
When I check the balance of Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX this is 999.2 QRK.

What happened and can this be explained?


Yes, this can be explained, but it has nothing to do with the Android wallet.  It is normal behavior and happens all the time for every coin.  I looked up the address that you mentioned and it is part of a transaction from February 16.

Code:
Transaction id:  567380523941ac9a0af38502a05c370180be956480df4ad1abd74214580b93a4

Inputs:
QZ7Lgj6eccCUKECbP855vDd8g1HyS7q5Ya -999.9

Outputs:
QiqEQmQWLgkTVrXLNUJN82wbAwxLq6Dxyu 0.7
Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX 999.2

A transaction has inputs and outputs.  The inputs will list the andress(es) of where the coins are coming from, and how many coins are being sent.  The outputs will list the addresses where the coins are going to and how many coins are being received.

You wanted to send 0.7 QRK to your phone.  Your desktop client looked at the coins it had available (which was in this address: QZ7Lgj6eccCUKECbP855vDd8g1HyS7q5Ya).  The client then looked at the coins available in that address:  999.9, 4999.9 and 4854.9.  The client chose the amount of coins most closest to the 0.7 that you wanted to send.  Therefore client makes a transaction to send 999.9 QRK.  0.7 QRK go to the Android Wallet address and 999.2 are returned to a newly created QRK address Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX, which is then stored in the desktop client's wallet file.  Now your wallet has two addresses in it.  One is QZ7Lgj6eccCUKECbP855vDd8g1HyS7q5Ya, which is the address to which you recieved the 999.9 QRK (but now has a balance 999.9 less than it did before).  The other address now stored in the wallet is Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX and it has a balance of 999.2


It sounds like you accidentally set up a transaction fee on your desktop wallet. It's also possible that you downloaded something and someone is trying to steal your Quarks.



- I have no idea how to set up transaction fees on my desktop wallet. I have done transactions later but then there was no 999.2 QRK send. I have still one of the first versions of the wallet (the one available in December 2013)
 
Which balance is the correct one? The explorer balance or the desktop wallet ballance? The desktop wallet balance does not indicate that there is 999.2 QRK gone or send. If someone tried to steal my Quarks did he succeed? My wallet is encrypted. How can I restore the 999.2 Quarks, or cancel the sending?

The explorer indicates :"not yet redeemed" after one week

Which balance is the correct one?  The block explorer or the desktop wallet balance? The answer is both are correct.  Your desktop wallet balance does not indicate that there is 999.2 gone or sent, because it was returned to your wallet using a different QRK address.  Your Quark Wallet contains many addresses.  The block explorer only displays the amount of coins for a single address, so it reads as being 999.9 lower than it was on February 15.

This is not a matter of setting your default transaction fee.  No one has stolen your coins.  It is how Quark, Bitcoin and other coins are set up.  It is similar to making change for a $20 bill.  The person that you buy the bottle of water from will take your $20 bill and return to you $15 at the State Fair.

The coins in Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX (999.2) say not redeemed because you have not spent them yet, but they are still yours.

Here is the latest update:
https://github.com/HashEngineering/quarkcoin-wallet/releases/download/v0.1.4-beta/quark-wallet-0.1.4-beta.apk

Fixes include URI schemes.

quark:QLtLcRLMCshyFisUR2e3YSSqwbR4DjdT46?amount=40&label=Hash%20Engineering - if you click this link on your phone with the Quark app, it will load the send coins screen with my address and the amount of 40 QRK.
Hmm..I don't seem to be having any luck with this at the moment...When I click the above URI from my phone, I get "webpage not available"..
Also, when I perform a send request to gmail or through my android messaging app, it does not come through as a URI..
Anyone else having better results?

Actually the link on this thread does not work because bitcointalk.org puts an http:// in front of it.  But I also noticed that neither my Samsung browser nor the Chrome browser will start the Quark app if I put this text into their address bars.  However, if I put a link into the page at: http://www.hashengineeringsolutions.com/quark/, the first link in this page will open the app.

The "link" does not work in email's or texts, because the Texting and email programs (Gmail) do not recognize it as a URI.  Many other apps may not either.  This feature doesn't work too well, except for generating QR codes that can be scanned while on the phone.
