[XMR] Monero - A secure, private, untraceable cryptocurrency

[sleepdog]

...do we have any up-to-date community built binaries so I could try out the DB version on my Windows box? I know of the cautionary notes and caveats, just wondering if anyone has published binaries yet.

This is from last week: https://downloads.getmonero.org/monero.win.x64.v0-9-beta.zip

Exercise the appropriate level of care with it being a beta. We've recently found and solved what we hope to be the only major, breaking database issue (that could have caused major issues if we'd tagged prematurely), but that means that prior LMDB sync ups have to be resynced from scratch or imported from a fresh blockchain.raw export.

I've been trying this on my Win7 machine. I managed to blockchain_export ok from my blockchain.bin, but trying to blockchain_import resulted in the following errors:

This may be an obvious question, but you have enough free disk space, right?

Will you PR it to the offline generator?

https://github.com/moneromooo-monero/monero-wallet-generator/pull/1

Thanks, merged, signed, and pushed.

Addresses generated earlier are still totally valid of course, and can be restored with simplewallet.

Hi Guys:

Sorry I was away from this thread for a while (and I missed posting in the "leet page" too... dammit.  Oh well LOL)

Anyway, so, I am to understand that that weirdness I posted *was* an actual bug in the offline address generator? 

And now it's updated so's things *should* work the way I was expecting them to work now?  Yes?

If so, I'll try it ASAP and see, and post back any results (or more weirdness) here.

Summary: What I'm really trying to do here is to be just a normal simple end-user of Monero using the most simple and easy available tools or methods as possible.

Read: that means NOT actually running the "difficult" command line only Monero program  LOL

Basically I want to be a Monero supporter, buy and hodl some now from the exchanges (vs mine it) but I don't want to trust keeping my coins on the exchange. 

So I want to be able to make secure cold storage offline address for sending the coins to from Poloniex, BUT at the same time wanna be reasonably sure I can get the Monero BACK under my control again, to either send 'em back to Polo or otherwise move/spend 'em sometime "soon" if necessary, again using only currently available SIMPLE tools and methods.

Unless I'm missing something, this means basically MyMonero web wallet for the near future, unless and until some day (soon?) the official Monero GUI will actually appear (hope hope?)

SO: long story short, what I was thinking should hopefully work smoothly would be:

1. Buy XMR on Poloniex
2. Run Moo's program on offline secure computer
3. Get safe/clean Monero address from #2 and save/print mnemonic safely!
4. Send Monero out of Polo to address from #3 for long-term cold storage
5. Sit tight knowing my Monero is secure
6. If needed, enter mnemonic key saved from #3 into MyMonero log-in
7. Coins sent to this address at #4 SHOULD BE THERE???
8. If #7 is true (??) send Monero back to Poloniex or whatever...

So IS this how it'd work now?  Any problem or flaw in above?

Explained by luigi1111 below:

I can answer this.

It's due to the way the MyMonero code derives the viewkey, which is different than simplewallet. Now, for "MyMonero" 13 word seeds, this is correct as it's the established behavior. For 25 word seeds, things can get a bit wonky.

Without getting too technical, simplewallet only generates "seeds" that are valid private keys, but will accept *any* 25 word seed. Mooo's address generator currently produces random seeds, not ensuring they are valid private keys. Due to the way MyMonero creates the view key, it will come up different ("random seed" vs "valid private key seed").

If anyone is interested in the code, I wrote it up here a few days ago: http://pastebin.com/MHYZzWWz

Simple answer: if you send coins to either of those addresses, they'll be recoverable; you'll just have to pay attention (you can "properly" generate the view key from the seed and log into MyMonero with the "Login with Public Key" if you want).

Bonus: here's the seed for that address which will work for both simplewallet and MyMonero (will produce your first address):

And now it's updated so's things *should* work the way I was expecting them to work now?  Yes?

Yes.

Unless I'm missing something, this means basically MyMonero web wallet for the near future, unless and until some day (soon?) the official Monero GUI will actually appear (hope hope?)

Quoting myself here from reddit:

GUI will probably be released after libraryzing is done (devs are currently working on it, see design goals -> https://getmonero.org/design-goals/), without libraryzing it makes no sense to "wire up" the GUI.

The design is already done, see following link for some sneak peaks -> http://imgur.com/a/ERheR

1. Buy XMR on Poloniex
2. Run Moo's program on offline secure computer
3. Get safe/clean Monero address from #2 and save/print mnemonic safely!
4. Send Monero out of Polo to address from #3 for long-term cold storage
5. Sit tight knowing my Monero is secure
6. If needed, enter mnemonic key saved from #3 into MyMonero log-in
7. Coins sent to this address at #4 SHOULD BE THERE???
8. If #7 is true (??) send Monero back to Poloniex or whatever...

So IS this how it'd work now?  Any problem or flaw in above?

This is correct as far as I know. If you want to be superduper safe, you could use this tutorial by GingerAle -> https://www.youtube.com/watch?v=GJQ5prfNfZQ

Regarding #6, this is possible but will cost you 10 XMR. Importing into simplewallet is free.

<fluffyponies hate this guy

If you create the seed, then log into MyMonero with it, THEN send coins to it, you won't have to pay the import fee (I think). It won't be a "real" cold storage account at that point though. You might as well create an address @ MyMonero instead to be honest. Of course it'll be a 13 word seed instead of 25 word, if you have some reason for preferring one over the other.

Edit: looks like saddam hasn't updated http://moneroaddress.org yet. Grabbing mooo's version from Github should work great.

[saddambitcoin]

I will update moneroaddress.org later today

That's correct - the import function is a convenience tool for people who want mobile access to an existing wallet or similar. It chews up some of the CPU cores on the backend (and hammers the disk) whilst it scans through the whole blockchain, so the fee is for us to offset the added cost of extra availability for this.

will it build??

hey hey computer will you compile that?

DO NOT DEPOSIT XMR TO CRYPTSY !!

It's NOT POSSIBLE to withdraw coins once you deposit!!! Their system is broken or so they say. Very suspicious!
I opened a ticket almost 4 days ago, still waiting !!

DAY 7 , STILL UNABLE TO WITHDRAW!

FUCKING CRYPTSY SCAMMERS!!!!

Just a little side bar for you.

This is a ploy often seen on exchanges who are still trying to accumulate a position in the coin, and really just don't feel like buying it. So instead, you're footing the bill.

Just like Poloniex has had more than one mysteriously 'not creditable' deposit due to 'software prblmz n stuff' from a year and a half ago, cryptsy is now doing the same thing.

It's okay though, look at how fantastic Poloniex turned out!

Yep, hundreds of GB free.

Can I mine simultaneous on different machines using the same XMR address ?

And then you can enter the arbitrage bussiness between Cryptsy and Poloniex.
Just kidding, of course.

what can i do? its still there, os x yosemite after maybe 72H:

Code:

......

[warn] kqueue: Too many open files
[err] evsig_init: socketpair: Too many open files

do i need to restart the node automatically to prevent this? i want to have this node running 24/7, especially since it runs so smooth except this issue (i run testnet + normal on the same macbook)

Version it says ( ):

Code:

bitmonero v0.8.8.7-f7c27f8

should i rebuild?

This problem is still being worked on. I can only recommend restarting periodically as you proposed. It only affects Mac OS.

Nope, i am sorry to say that this same bug is affecting Linux64bit also

I guess I got bad information on that, but it could be good news since that may make it easier to debug.
