GameCoin v0.8.2.1 released:
Quote
Fix an issue with the difficulty retarget where it is using only the last 48 blocks to determine where the next difficulty should be. The previous system can lead to difficulty swings of the maximum variance in the event a miner puts a lot of hash power onboard only in the times when the difficulty is low.

As from block 62400 the difficulty algorithm will work out the block time average from the last 12 retarget intervals (576 blocks). This should be the equivalent of 24 hours worth of blocks when the network is running efficiently.

I'm sorry, but you're not "just mining". You appear to be exhibiting very hostile mining habits. You throw your hash rate at a coin with a low difficulty until it retargets causing a massive difficulty increase. At which point you then leave that coin/blockchain and jump to another one. In the process bringing the network to a halt/slow crawl. After hours of others mining and trying to get the coin to recover with a lower difficulty which matches the network hash, you come back and repeat the process.

Despite what you say, I see no evidence of your supposed 110 mhs still on the network.

You are essentially attacking the coin by means of a high difficulty attack.

This is not something that happens accidentally, it is an intentional attack on this and various other coins that you mine with the same method.
Watching the blockchain and the rate which blocks are solved, you can clearly see the start of the difficulty attack by tanking the network, and the damage it inflicts when you leave.


Please prove me wrong on this assumption. Wink


I'm not attacking Gamecoin, if I wanted GME dead it would be dead as I was more than 75% of the networkhashps for about 24 hours and could easily be 90% or better with a few tweaks. All I am doing is mining and switching coins when it becomes more profitable, you know kinda like a few pools and a lot of miners do with alt coins using Coinchoose. I just don't use Coinchoose pool or software.

The reason the drop is drastic when I quit mining is that while I am mining a lot of fair weather miners pull off due to the diff rise and mine elsewhere. So when I leave you get a combined effect.

FYI, I was never going to mine GME to begin with until one of your coin devs starting giving me crap about pointing out a flaw in Ahmed Bodi's pool. A flaw where a miner could mine at twice the normal scrypt speed, produce all rejects and still accumulate paid shares.

 I would be very careful about asking me to prove otherwise when I say I am not attacking your coin. If you would like I can absolutely demonstrate the difference between simple mining and killing it so that you won't be confused in the future.


I await your answer.


~BCX~




such a menacing/threatening response is uncalled for, people are well aware of your feats. Some respect you some loathe you, making statements like this has the effect of making the yes become a no. your work has weeded out weak coins and helped people figure out issues let's keep it that way... just my two penises.

I see a bright future here, please contact the Steam team, since they have open sourced with Linux, perhaps they can go a bit further by accepting GME as payment and even encourage developers to allow GME generation and use in-game.

Indeed.

And thanks for the client and thread update Petr1fied Smiley

If you guys want this coin to survive then you're going to have to actually mine it. There are currently extra mining incentives in the high difficulty periods in the way of extra fees. A few days of putting up with this will see us to block 62400 and the difficulty swing will be nowhere near as severe as it is now.

It's time to step up if you want to save this coin.

Thats not an easy ask when we have idiots like bitcoinexpress mining the difficulty into oblivion  Roll Eyes

The only thing I can do is bring the hard fork forward as even block 62,400 is looking like an impossibility right now as the entire network has abandoned it due to the efforts of BitcoinEXpress. I'll look into where we're at tomorrow and potentially release another client but whatever I do it's going to need the miners to step up otherwise we may as well just declare it dead right now.

What's the changelog for this version? Is there any security breach or something near that? Mandatory Update is really hard word. Huh

I'll mine it. Only 400 kh/s, but it's a start

as soon as i've finished coding it, there will be a bot announcing every block which has extra rewards as an incentive for miners. once ive coded it, im going to raise the fee to 6% so that i can make the switch to proportional payout and then change the fee to 0% aswell as  100GME block finder bonus. I wont do it yet so i can give u guys some time to reply with your thoughts

according to the coin-specification the retargeting-frame should be 48 blocks.

But. it seems something goes wrong...

Or why isn't the retargeting-mechanism working correct ?

Or does it ?

It's quoted at the post I announced it along with the reasons for it being necessary:

Mandatory Update is really hard word. Huh

It's mandatory because the changes will cause a hard fork at block 62,400. Cryptsy and all 3 pools have already updated so if you don't update you will be on the wrong side of that hard fork.

according to the coin-specification the retargeting-frame should be 48 blocks.

But. it seems something goes wrong...

Or why isn't the retargeting-mechanism working correct ?

Or does it ?

It retargets every 48 blocks as per the specification however that doesn't help when people put excessive amounts of hashing power on it when the difficulty goes down and then pull it off again the instant it goes up. This is due to the average block time being calculated entirely off the last 48 blocks and this is what this hard fork seeks to fix. By looking a factor of 12 retargets into the history the average block time will not be skewed by such a small amount of data when calculating where the new difficulty should lie.

Fantastic work, everyone!  I was blown away when i noticed our little coin has blown up on cryptsy.

The good news is, this tells me that our little birdie definitely has some wings, which means I'll be focusing more of my personal time to porjects related to GameCoin, and making it simple and easy for developers and content providers to start using it as money.

That beingt said, if anyone has a game/game related business and you'd like to start accepting GameCoin as payment and need a little help, give me a shout.

And as for the coin being mined into oblivion... every system has rogue elements, and you can't always blame them for taking advantage of a situation.  However, excessively preying on a coin's weakness in this manner seeks to alert the developers quite quickly of a weakness in their difficulty algorithm.  Now we know, and now we can fix it.

There is something to be learned from every experience, and the coin will come out stronger for it, provided we keep learning as we grow.

Thanks!  I've been bogged down to all hell with my day-job and other personal projects, but I'm so glad to see our little community is alive and kicking, and (for the most part) working together so well.

I'm really excited to see where things are going to go from here.
