Flippin' burgers since 1163.
Wanted to convert some bits to Monero today using ShapeShift.io, but it says Monero (offline).

Strangely enough when I used the direct link https://shapeshift.io/?pair=BTC_XMR it worked perfectly fine, received the XMR within minutes. Is this a common issue with ShapeShift? Seems buggy to me (the btc balance shows zero, but you can just make the transaction anyway).

Edit: contacted ShapeShift.io support, waiting for a reply.

Is there any site where I can use view key to check the balance of the wallet? I guess I can use the simplewallet for that, but is there any site for it? Or any other solution?

I don't think view key lets you see balance, actually, only received amounts.

It does work for cold storage.

Alternately, if you can account for spends another way, you can then subtract them, giving a balance. This is a bit tricky to do correctly since change will be scanned by the view key, so you have to subtract the payment amount plus the change amount on any spends.


Yea. I am looking some way to check the balance of my cold storage, paper wallet. Would be great if the view key gave balance directly without need for user to do any calculations. But it is possible also that way.

But is there any site for that? Or have I to use some wallet software?

If you only want to confirm receipt of funds from one or a few transactions (and you know the IDs for those transactions), you could use http://xmr.llcoins.net/checktx.html.


yeah im trying to wrap my head around why the viewkey  / spendkey can't be used to scan for which output has been used as an input in a view-only mode. I know I've read it explained before, but I think it was on the order of "well the viewkey shows you what outputs are yours, and the spendkey lets you spend those outputs" . I mean I get part of the problem - having the spendkey does allow you to spend that output, so hence making a viewonly wallet with just the viewkey.

would it be possible (somehow) to hash the spendkey, and then somehow scan the blockchain with a hashed-spendkey...  but then you'd need to somehow extract from each transaction... the term i want to use eventually is dehash, and I know thats unpossible (indeed the whole purpose of the whole thing).

So I guess really the solution would be a 3rd key?

What was the new enable-tracking or whatever I saw in the simplewallet. didn't I just recently ask this? i need more sleep.

No, that, uh, won't work.

What does work is creating key images for every output discovered by the view key scan. Of course this requires bringing your paper/cold wallet at least to a running state (can be an offline computer).

There is no (merged) simplewallet stuff for this yet. It'd be something like "watch-friendly"; store-tx-info is not related at all.

New version of LightWallet available: v0.2
https://github.com/jwinterm/LightWallet2
https://github.com/jwinterm/LightWallet2/releases

Now written in Java using Libgdx library, designed to work with Monero release v0.9.x.
...


Do you happen to have any documentation for compiling the jar from source?

(and Thank you!  This has the potential to be huge!)

It is a gradle project, so, at least using eclipse you would just import the root folder as a gradle project, then export the desktop sub-project as a runnable jar. I'm pretty sure it's fairly similar using other ides or gradle on command line.

This is for importing a freshly generated project, but should be similar/same:
https://github.com/libgdx/libgdx/wiki/Gradle-and-Eclipse

Their wiki is very helpful in general, also instructions for exporting executables for different targets there. The exe is just the runnable jar with a logo icon.

I think only using simplewallet right now, but it is possible someone else knows of another way.

What is the command in simplewallet to that?

It is this one:

Code:
  --generate-from-view-key arg         Generate incoming-only wallet from
                                       (address:viewkey:filename) and save it

Looks like 25 words is the way to go. 
I have a 13 word mymonero wallet.  I would like to use a 25 word wallet, but I'm not inclined to do a kludge-y conversion from 13 to 25 words.

The conversion is not "kludge-y", it's rather simply impossible, unless you happen to be a lucky ~6%-er.
I downloaded the monero wallet generator from github, which was linked to in an earlier post.  I'll make a new wallet and send all the Rita Morenos Cool from mymonero.com to the new wallet.

You could always test and see if you're a lucky ~6%-er. Tongue

There is not yet a site for monero paper wallet generator. But we can have such a site by slightly modifying mymonero.com.

Try this site: https://moneroaddress.org/

You can save that page and use offline.



Well that is i great site. How long has it been alive? There is more words in mnemonic seed than mymonero.com creates. Is this a new feature of monero or the site?

It has been online for quite some time now, I think 6-8 months. Simplewallet and Moneroaddress both use 25 words mnemonic seeds, whereas MyMonero uses 13 words mnemonic seeds. You can read a bit more about it here -> http://xmrtests.llcoins.net/addresstests.html

See "How Cryptonote Addresses Are Created".

Mooo's 1st commit is June 15th. saddam hosted it very shortly after that IIRC. I've also had a very simple one up (http://xmr.llcoins.net/) for even longer.

There is really no reason to use a 13 word seed except for ease of storage due to length. Obviously 13 words is only half the bit strength, but neither are close to practical to attack yet.

As I'm sure your well aware of Java has had a slew of security issues and people are hesitant to use it for banking. Can you assure the community that the libraries that are used in this app have non of these flaws? Also why would you use a game engine library? I'm not a Java programmer so would you elaborate on that choice?

That first statement seems to be quite a bit of a generalization. Java seems fairly popular among banks, especially investment banks, after some cursory googling. No, I can assure you of nothing - use at your own risk. I can tell you the only libraries it uses besides Libgdx and standard ones are Google's Gson and LWJGL backend for rendering on the desktop. I'm not (much of) a Java programmer either, and I chose Libgdx because it was something I was interested in learning, because it allows (relatively) easy deployment to Windows, Linux, Mac, Android, and iOS without changing much if any code.

Thanks alot for the quick and honest answer.

https://github.com/jwinterm/LightWallet2
https://github.com/jwinterm/LightWallet2/releases

Now written in Java using Libgdx library, designed to work with Monero release v0.9.x.

To run:
  • Download binary (jar or exe for windows).
  • Put in same directory as simplewallet (and if on windows libeay32.dll, libwinpthread-1.dll, and ssleay32.dll).
  • Import wallet or create new wallet following instructions in program (following instructions in program).
  • Use default remote node or swith to http://localhost:18081 if running your own bitmonerod.
  • Try to let wallet sync before closing for the first time.

You shouldn't be in any danger of losing coins, as you will either import a keys file or seed, or create a completely new wallet and then delete/encrypt the sensitive information.

There seems to be a possible issue in counting previous transactions in a wallet file. If your unlocked and locked balance are green in the wallet tab, those are the numbers you should trust, and if they're green it should be OK to send a transaction.

It can take quite some time to sync a wallet, especially an old wallet with lots of txs on a crappy computer using a remote node - it might take up to several hours.

Please let me know if you have any issues, by posting issues on github, PM here, PM on forum.getmonero.org, here: https://bitcointalksearch.org/topic/lightwallet-a-lightweight-account-manager-for-monero-903579, or here: https://forum.getmonero.org/20/general-discussion/166/lightwallet-a-lightweight-monero-gui-account-manager

Hello! I've been away from this thread for long, sorry if I'm posting boring stuff now.
I've started mining xmr again (for the fun of it).
I'm using Wolf0's opensource miner and stock clocks.
Getting 678 H/s on 290x and 687 H/s on Fury, are these good hashrates?


Those are pretty good. I think you can modify some of the settings in the .conf file to boost the numbers.

https://github.com/wolf9466/wolf-xmr-miner/releases/

are you running the 0.3?

I compiled from git (linux), played with worksize and rawintensity, did a couple little modifications to the opencl files.
Power usage is very low.
As far as I understand, it's more profitable than claymore, if you count the fee.
