Finally, I will like to set up several master nodes, I lack the technical capability and time to do it myself but will be hiring somebody to do it for me. In that sense I would really appreciate a comprehensive guide on how to set up the master nodes, I think that would be a way better use of the time of the more technically inclined in this forum. Thanks

I'll bet someone will come up with a basic guide and I know the developers are going to try to build safety  into this, but do be sure, especially with that much invested, that you cover all security issues possible.  Just saying Cheesy

The only real security issue I can think of is that somebody uses the same password as he uses *everywhere* or doesn't even encrypt the wallet.dat and somebody steals it.
Otherwise, you might get a DDoS attack, but that's just painful, not permanently harmful.
And with that attitude you can say goodbye to your coins quickly.

What people aren't realizing is that by having a master node, you are essentially waving a bright flag saying "Hey, at ip address: xx.xx.xxx.xxx there is $700 (and hopefully a lot more!) just waiting for you to take if you can find it."

And you're thinking, but even if they could hack my server, I still encrypted my wallet with a 32 character password! Well guess what? If you have a master node, it means you're most likely active in the cryptocurrency community, so I can find you. And I can almost guarantee if I could break into your server, that I would be able to link you to both your online persona and your real identity.

And now with all of that, my social engineering attack would begin, you wouldn't even know I hacked your server until maybe even as long as 6 months later, when I crack the password guarding it.

My point is thus, having a master node out there is not something to take lightly unless losing the balance of the wallet is no big deal to you.

I think it is a fantastic idea, I am just warning people who don't have the right skills that having a master node is not for them. And if you have to a.) ask how to set one up or b.) have to ask if you have the right skills, 99.9% chance you should not be setting one up.

This is a very good point. Is there anyway to obscure the Master Nodes real IP address?

Edit: Scratch that. A master node operator could just run it through a proxy or tor.

I still can't see how you might get my long random password which I never exposed to an online computer (just generated while running offline in a Live environment and printed out to a paper with a non-smart printer) by following me on Facebook. Roll Eyes
Good luck with that. I rarely post anything meaningful. Tongue

This is why I am concerned if I need to periodically refill the keypool manually.
It would look like shutting down the node, copying the wallet.dat, booting up an offline PC, refilling the keypool after scanning a QR code with a webcam, copying the wallet.dat back, restarting the daemon...

I personally am not much of a hacker (black hat at least), but I know/talk to people who are, and you are their favorite type of victim. So confident they are secure that it makes it so easy to get an attack in right under their nose because they are absolutely convinced they are invincible.

I'm not saying it would be easy, or that it even would work on you, that is up to a million factors, a non-negligible one of which is pure chance, but if a good, determined hacker wants to RAT your computer and they know a fair amount about you, it is going to happen. If I have access to a server you own, assuming the hosting company has your real contact information, I am going to have your address within a few days from *most* companies, if I wasn't able to already have it through other means. And if I have your address, and as I said, determined enough, most consumer routers have vulnerabilities in them, especially if you don't have the latest firmware. So once I've compromised your router, it is a matter of time watching your traffic until I find something I can exploit, and boom, RAT'ed.

But even more so, as you said, you printed it off. Maybe I'll just break into your house and look around when you're at work.

(By I in the above I mean a nefarious hacker, which I personally am not.)

1.) For $700, most of what I said is not realistic, but for $2000, $5000, $10,000? You bet your ass it is to some people.
2.) You might think everything I just said is ludacris, but I can assure you, it happens, a lot more often than you would think if you didn't have knowledge of it.


About the keypool, if the node is already running, why would you need to refill the keypool offline, all you would have to do is login to the node and run "./darkcoind keypoolrefill" and then backup the latest wallet. Realistically you could setup a cron script to do it that would be just as secure as doing it manually. (if someone got access to the server, they have the wallet, them finding out you encrypted it with a key and then pushed it into a S3 bucket named "wedding_photos.zip" (bonus points if you made the archive actually contain wedding photos which would fool *most* hackers if they got their hands on it) wouldn't matter, they would be able to download it straight from the server)

1.) For $700, most of what I said is not realistic, but for $2000, $5000, $10,000? You bet your ass it is to some people.

Of course, and you can steal even more than 1000 DRK by breaking into my house. What does that have to do with running a DRK node? I can think of a lot of easier ways to pick a house for breaking into.

May be, if 1 DRK will worth >=10$. Oh well, I will be paranoid about my DRK (assuming I am still holding that much)! But I guess the masternode requirement will be lowered by then and I can keep most if it somewhere safer.

That's the problem...
I never want to expose my password to an online machine until I absolutely have to (which is when I want to spend the coins from that wallet).
Having to periodically refill the keypool makes this complicated.

Dark Wallet getting ready to for live testing.

http://www.reddit.com/r/Bitcoin/comments/227lne/darkwallet_update/

Interesting Q&A:

Q. Will it be possible to connect the wallet to other cryptocurrencies? Litecoin, Peercoin, Primecoin, etc.

A. caedesv

The first version is going to be bitcoin only (well and testnet coin but maybe not at the same time). This way we avoid some complexity and also can deliver on the initial promises.

For next stage we're totally considering make it multi-currency (and other goals). Should be easy and at least with some coins looks like we can even use the same bip32 tree, one key, many currencies.

Could someone who knows their sh*t explain to me to difference between Darkcoin and Darkwallet? Is it likely to make DRK redundant? I certainly hope not as a fan/holder of DRK!

Anyone? A little help  Smiley

Can someone explain to me what is going on in this block/transaction?  Block 17543 (000000000542628747303786cb09be1456998508cc3d70ede07b16c20fe75514), the only transaction (1b4c93a3bf49ad4855f74121aea68517b1073fd3a75943e19f956ae553cd2207), specifically the third output

And to make things easier, here is the transaction:

It's easier to see in the explorer:
http://chainz.cryptoid.info/drk/tx.dws?1b4c93a3bf49ad4855f74121aea68517b1073fd3a75943e19f956ae553cd2207.htm

It looks like some coin was sent but it was broken up in a payment and a fee?  But not sure?

It's p2pool generated block.

example

Every miner is welcomed aboard! We just added 3 more dedicated servers to our cluster, now the pools are snappier. We also upgraded MPOS, fixed the shares issues regarding the x11 algorythm. Also, we have 16 stratums to serve our users. Join us to enjoy the benefits of our strong architecture and knowledge!
What shares issue?

Old news, pre-DGW I think.

No, basically after updating to the new mpos, we had to fix the amount of displayed shares in MPOS because it was not correct anymore. We now have the right values so our stats are now showing more accurate numbers. X11 is not supported by MPOS officially.

Dark wallet is a centralized mixing service where you use a browser extension to anonymize transactions.  Look at this screenshot: http://i.imgur.com/FA7TIA6.png  . You can see it's routing all of the traffic through gateway.unsystem.net.

So here's our advantages vs dark wallet:

1.) We're decentralized. The clients automatically discover all masternodes and will use those
2.) Everyone will use DarkSend by default. The problem with a product you must setup like this is you'll have far fewer legitimate users to mix with.  
3.) Masternodes create a new type of investment opportunity within our ecosystem much like mining. The result? We get a ton of super high quality full nodes, anonymity and happy investors.
4.) If they're accepting inputs and outputs separately they can be shut down simply by a user offering an input, but refusing to send the output. If they're accepting inputs and outputs together, it's not anonymous and it MUST be decentralized to spread the knowledge of who did what to keep anonymity. My guess is they're taking inputs and outputs separately and banning inputs that do this. In that case you could attack it by using another mixing service to get fresh inputs.

Thanks for the explanation, Evan. Darkwallet is certainly inferior. I'm not worried now!

It bugs me that they're getting all the attention and you're not. Just a Google search of Darkwallet brings up a lot of hits.

It seems like -keypoolsize allows for <=500 keys (it will generate more but it won't save the rest in the wallet.dat file).
I think this should be increased by a few magnitudes for DarkCoin.

what is the best way at this time to buy DRK.

From Fiat.

Buy litecoin or Bitcoin ?

Where to buy them from fiat ?

Where to exchange Lite/bitcoin to DRK.

Most people recommend to buy bitcoin on Coinbase, then send it to Cryptsy and buy DRK there.

well...cryptsy is good for btc/ltc or many other cryptos to drk. Moolah has a website to convert fiat to alts. prelude.io

Just a reminder to everyone - if you haven't subscribed to http://www.reddit.com/r/DRKCoin/ please do so!

We should try to build the community as large as we can before the release of darksend!  Grin

Evan,
Darksend is a much bigger feature than what it seems to be in the windows wallet (just a checkbox in 'send' tab currently).

Instead of having this checkbox inside the 'Send' tab, I propose the following:
1) remove 'Use DarkSend' checkbox
2) add a 'DarkSend' tab between the 'Send' and 'Receive' tabs*
3) this new tab looks and functions exactly the same as the send tab but it uses darksend technology when submitting.


This will be much better UX to differentiate this technology from standard technology.

* You can also consider putting darksend tab before the send tab.

I don't like redundancy. What about this? -> The QT client immediately switches to a darker GUI skin (basically a dark gray [current coin logo color] bakcground) whenever DarkSend is checked. (And may be the checkbox gets a little bit more notabale on the Send tab.)

Just remember, newbies already find wallets confusing. They are simple and easy to navigate if you use them regularly.



True, but I like coinzcoinzcoinz suggestion, because as he later said, you can explain how darksend works, warn of disconnection fee, etc... make a nice big progress bar or some such to show how things are progressing, and have room for that information, making it less complex to use in the end (along with a warning that you're not using privacy features in the send tab)

Wallet is ok for now IMO.  Get the main event sorted (DarkSend), then worry about stuff like this.

Evan, I have a question about the specifics of a darksend transaction. I don't remember the answer being in the documentation released thus far.

Can darksends be sent with just the inputs properly signed by the private key, but without the private key actually being present? For example, can I create the tx on an offline computer and only move the transaction info to my online computer, and send it from there?

Looks to me like only 989 of the DRK you sent made it to your destination node.

Your output posted: http://explorer.darkcoin.io/tx/517b323b43cdb93fb254d40fafb105d2b9527d917d0046139823eb6a928a565a

But it was already sent off, and the large final output is 989: http://explorer.darkcoin.io/tx/3f2e6bf24bf82023c3f9ff51c9bd82c1032977caa39e34ce92c4199ade70777d#i0

Looks to me like only 989 of the DRK you sent made it to your destination node.

Your output posted: http://explorer.darkcoin.io/tx/517b323b43cdb93fb254d40fafb105d2b9527d917d0046139823eb6a928a565a

But it was already sent off, and the large final output is 989: http://explorer.darkcoin.io/tx/3f2e6bf24bf82023c3f9ff51c9bd82c1032977caa39e34ce92c4199ade70777d#i0

I though it might won't be as easy that I simply withdraw 1000 DRK from Cryptsy. Grin
