Title: Sudden loss of BTC production Post by: racerx on October 31, 2010, 08:55:03 PM Hi All,
Im thinking nothing is wrong but I seem to have an odd production rate of bitcoins. I have a number of servers producing bitcoins (50ish cores) but all of a sudden my production seems to have halted though they all are getting new blocks, are still hashing correctly. Has the difficulty just ramped up alot or something else I haven't noticed? Code: gonk@prod-web2.xxxxx.net:~$ bitcoind getinfo All the servers are ticking along fine, and they connect out thru a central bitcoin server, but no more BTC since the 26th :( Cheers Title: Re: Sudden loss of BTC production Post by: ribuck on October 31, 2010, 08:59:36 PM Well the difficulty has just ramped up to 3091.
Why don't you estimate your total khash/sec and type that into the Bitcon Generation Calculator (http://www.alloscomp.com/bitcoin/calculator.php). See if you've gone longer than the 95% expected time-to-generate at the current difficulty. Title: Re: Sudden loss of BTC production Post by: racerx on October 31, 2010, 09:13:00 PM Will do, but that probably wont take into account the previously generated coins at a lower dificulty.
Also, when did the difficulty go up? Title: Re: Sudden loss of BTC production Post by: ribuck on October 31, 2010, 09:17:53 PM Within the last 24 hours.
Title: Re: Sudden loss of BTC production Post by: racerx on October 31, 2010, 09:39:44 PM Thanks for the info,
Im generating at about 76230 khash's and with the current difficulty it estimates: Average 2 days, 0 hours, 23 minutes 50% 1 day, 9 hours, 32 minutes 95% 6 days, 0 hours, 57 minutes Derived from a collection of hardware Im using and the hash rates I just documented here: http://bitcointalk.org/index.php?topic=1628.0 So I guess that means I'm still a day away from 95% with my last 50BTC coming in on the 26th.. just odd with at least 50 a day untill then. Title: Re: Sudden loss of BTC production Post by: racerx on October 31, 2010, 10:00:29 PM Right,
So I just discovered that my 2 6core miners (30khashes combined) have not been taking ntp updates for a while and are about 6 hours in the future. Just reading the http://bitcointalk.org/index.php?topic=960.0 (http://bitcointalk.org/index.php?topic=960.0) clock thread and Im thinking that might not have helped my cause. Title: Re: Sudden loss of BTC production Post by: ribuck on October 31, 2010, 10:28:33 PM So I guess that means I'm still a day away from 95% 5% of the time you should expect to take longer than that 95% estimate.Title: Re: Sudden loss of BTC production Post by: ShadowOfHarbringer on November 01, 2010, 12:38:09 AM So producing new coins is becoming hardly worth the power needed to produce it...
Exactly as predicted by satoshi. Recently I had to shut down minting on my computer completely, because my electricity bill went crazy...

Title: Re: Sudden loss of BTC production Post by: ShadowOfHarbringer on November 05, 2010, 08:34:47 PM still no coinage :( must be uber unlucky On what hardware ? Title: Re: Sudden loss of BTC production Post by: Marko on November 10, 2010, 03:38:56 PM Someone came in with a large amount of GPU power that day. I noticed the dent in my own GPU production as well.
Title: Monopoly back again? Post by: davux on November 10, 2010, 03:56:35 PM So does this mean that producing coins will be impossible to do by average people? Which would mean that the number of computers able to produce coins is reducing: it's only the big ones – the average guy is out of the way. Can it happen that in the long run, a couple hundreds, then a couple computers get the monopoly on coin generation?

Can it happen that in the long run, a couple hundreds, then a couple computers get the monopoly on coin generation? I don't think so... it will get harder and more spaced, but I'm sure others have experienced the odd block found by the 2MHs machine, just like I do. Title: Re: Monopoly back again?

If it used to take a GPU farm X minutes and an old CPU Y minutes now it takes them 4500X minutes and 4500Y minutes respectively. No one picks up any advantage, it gets harder by the same fraction for every imaginable set up. In a way you could say that the faster you were then the more you lose. |
