It's called hard fork because you're forcing users to update their clients. If 50% of the clients still run the old code they can create their own blockchain (that's called chain split), because after block X old clients will stop accepting blocks from new clients and new clients will stop accepting blocks from old clients. The blocks will be rejected because of the difficulty difference (which will be different between old and new clients most of the time).

Here are lines of code in CBlock::AcceptBlock() that will cause this effect:

    // Check proof of work                                                                               
    if (nBits != GetNextWorkRequired(pindexPrev, this))
        return DoS(100, error("AcceptBlock() : incorrect proof of work"));

So if more than 50% run the old client by the time of block X, it's the people running the new client will be left out.

(Sorry, I was not sure what details you were expecting in the answer. Hope this helps.)

could anybody tell me how many moons have been mined now?

These folks talking about the wallet containing a virus... let's address that one again first:

FACTS:
- There was a fake wallet linked to back on launch-day that was not official and was confirmed to be fake.
- The official wallet executable turns up the same false positives as recent versions of Dogecoin-qt and Bitcoin-qt wallets.
- I have personally been running the official wallet since forum member Nocoin submitted the binary to me and have not lost anything.

Now, what's clear is that I do not know what is going on with these folks reporting these weird transactions. I have not ruled out that these folks are merely making stuff up to cause trouble because I can't find any reason to suspect the wallet. I know the same code is run by many pool operators and none of them have reported anything suspicious.

Since irc.cpp has no command syntax, it's obvious that this is no the vector in use. It's well documented that this is intended for peer discovery only. I also don't see any wallet addresses in the binary and the wallets that these coins appear to be going to have only one transaction inbound, so nobody is moving these coins (which further lends itself to the notion that this is all troublemakers).

When I release with the new Kimoto Gravity Well support, we'll have new wallets anyway. I have been successful building the wallet on Windows 7 and have recently received instructions for OS X. Right now I am porting the GUI changes from the 0.6.4 wallet to the 0.8.6 wallet.

Been using the same wallet since release.  I am good at wallet stuff, if you need a hand let me know, I am hands on guy, I not gonna tell ya how to do it.  Thats big money, I am sure you want someone to help you out.


I doubt you have a bug wallet.

Or you could just so two-step authentication and then they have no way to do anything even if they break in.

I am very interested in what your colleagues can find. This mysterious coin-grabbing should be tackled very soon as it disturbs a lot of good vibes for this coin  

Sometimes is better shut up and appear to be silly, than speak and confirm it.

You are a "Professional reverse engineer and former Professional Anti-Malware" and get owned you investment with malware.... Please get a new job... I can't believe this, you are a liar.

please be carefull, a lot of people are discovering the value on MOON and have lots of ways to break your computers
security, thats why the hackers are aiming at MOON now,

if you hold any important ammount of MOON coins, please use PASSPHRASE before you claim your a "security expert"
and for love of Coins !!  save it in COLD STORAGE, if you know what that means... if not i can explain it to you to increase your
security ...

Spread the MOON love !

lol, wow, your credentials are impeccable.  "Professional reverse engineer", outstanding /sarcasm.
