If using bitcoin-qt client, click on receive button, find the btc address requested on that list, right-click on it->Sign Message. Now copy and paste the message to sign. The rest should be straight-forward.

If you're using blockchain.info, click on "receive money" tab, look for the btc address requested, click on "action" on the right side and pick sign message.

Now that most of the technical problems have been handled, does that mean you'll be turning vardiff back on soon?

I just found this coin and the concept behind it is really interesting. But can someone explain how exactly human mining by playing a game works and how does it fit in with normal mining? For example, how do you prevent cheating? How does the game maintain state? Is this being done directly on the block chain? I'm mainly trying to understand how this gaming idea works under the hood and how it fits in with p2p cryptocurrency.

We're the fastest Crypto-Currency exchange, and we're growing quickly.
..

There's barely any depth for the orderbooks for the trading-pairs currently there, suggesting there's no real load on it atm. That being the case, of course it's easy to claim you're the fastest crypto-exchange. If your exchange can handle the load and traffic of the other exchanges then maybe your claim above would have some significance.

When I get answers to these questions I will decide will I invest or not. And please, after you read this and you go to leave a reply please remember that I am not here to bash all of this. I am also a potential investor but just very careful one. Many people missed the NXT boat, me too personally and now are jumping to anything just not to miss another boat. I don't wanna be greedy and in this way lose my hard earned money, that is why I am writing this and investigating. Let's face it, there is just a lot of scam out there.

Completely agree with zorke here. Ideally for me, I'd like to:

 1. See the whitepaper released.
 2. Have a precompiled binary to play around with testnet.
 3. Show some kind of proof or indication of he's qualifications. For example, any side projects he or his team have worked on in the past they wouldn't mind sharing(possibly on github or bitbucket)? Doesn't have to be crypto-related. Do they have a stackoverflow account where we can check their profile?

before any btc funds get released.

getting close to launch and still no password encrypted wallet uploaded yet? It's starting to look like a fail launch to me.

please pre-upload the wallets to a password protected rar file. That way all you have to do at launch is give out password and push the source to github. Way too many fail launches this week.

Was wondering, has the OP or any of the other dev members contributed to another open source project or their own project on github or bitbucket that we can look over?

153  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [pandacoin] The Panda Coin ♥ Scrypt Adaptive-N w/Kimotos Gravity Well ★ on: February 21, 2014, 02:26:09 AM
Is it even possible to code a coin like that? What are these "codes" anyways? Every time a coin is announced, I feel it's just a bunch of junk pulled out of think air hoping it'll succeed anyways.

Yes, something like this should definitely be possible even with bitcoin. That's how you implement more advance features like contracts and such, they're build from basic conditional primitives such as this. There's an article in the bitcoin wiki showing how a distributed exchange can be implemented w/o trusting a 3rd party -- nlocktimeout is set to timeout in 24h-48h for the coins being traded. If the trade doesn't complete by that time then the held coins are returned to the original owner. Before that timeout period though the coins are not redeemable by the original owner.

I haven't looked at this more closely but I don't see a reason why you can't set the lock period to say 6 months, which could have completely prevented this diabolical from happening.
154  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [pandacoin] The Panda Coin ♥ Scrypt Adaptive-N w/Kimotos Gravity Well ★ on: February 21, 2014, 02:15:31 AM
Just wondering, since the devs and investors aren't allowed to touch their IPO's for 6 months, why wasn't this enforced at the protocol levelfrom the beginning? Like for example, set a nlocktimeout for 6 months so it isn't spendable until the specified time has elapsed.

Who is on the team? What is they're experience? Please be specific. Why can't someone invest less than 0.1btc for the IPO?

Also, IMO the premine at 5% is way to high beating even pandacoin's recent launch at 3% premine. Given the stigma and scorn the crypto-community has towards premined coins you guys should really reconsider your approach for this launch. Lowering it to 1% premine or less would make it far more appealing for more participants to jump in.

So when is panda coin going to show up in coinmarketcap.com?

What about http://panda.chaosagent.org? They have 0% fee, 10k block finder bonus, 0.1 panda withdrawal fee and 30 block confirmation time. I'm not sure why more people aren't flocking to that pool.
159  Alternate cryptocurrencies / Altcoin Discussion / Re: Nxt Scripts (progress and discussion) on: February 16, 2014, 02:02:14 AM
As I understand, the tx malleability in bitcoin is possible because the transaction id isn't being signed by the private key when doing ECDSA. Since Nxt is designed from the ground-up with its own protocol, why are tx id's still malleable?

If you design it so the tx id is part of the hash being ECDSA signed would this not address the malleability problem since changing the tx id at this point by an attacker would invalidate the ECDSA signature and consequently rejected by nodes?
160  Alternate cryptocurrencies / Altcoin Discussion / Re: Nxt Scripts (progress and discussion) on: February 15, 2014, 12:17:05 AM
Okay - let's get "stuck into it" (warning - this topic is going to include a lot of "technical" discussion).

So first and foremost we have the problem of "what kind of scripting language should we use"?

In considering this we have to understand that we don't wont Nxt nodes wasting large amounts of CPU cycles on scripts when there most important function is of course to process Nxt transactions.

...
So - is there an existing "low-level" language (close to if not assembly) that is suitable or do we need to "roll our own"?

I am not sure of the answer to this question and look forward to your input.

IMO, this isn't a new problem and its been solved many times before. I suggest checking out some of the scripting VM implementations out there first before reinventing the wheel -- unless you have an itch to scratch Wink

Given the above constraints and desired properties, I definitely recommend checking out and researching Lua as per Jack's suggestion -- it's lightweight, more performant than alternatives (eg. ruby, python), allows for a great deal of control and there's a very strong community behind it.

Since you're looking for some way to "instrument" opcode execution, maybe start with Lua as a base and modify its main interpreter loop. From there you can add hooks for whichever instruction that needs to be charged a fee. Lua also has a debug library that provides functions for hooking into the vm script execution. These primitives are used to implement debuggers and profilers but perhaps it can work for your use-case example too?

Another idea is to introduce new opcode primitives on top that better maps to the nxt transactions and actions you want to perform. If you look at Luajit as an example, it augmented its own custom bytecode along with Lua's which allowed it to apply some pretty impressive optimizations.
