Just thinking, I don't have the resources to do this, but I'd like to understand the math involved.

How much hash power would a guy need to solo mine, reasonably? I mean, one block a day, one a week, one a month and one a year. Is this calculateable? At the present difficulty level?

Thanks, if anyone sees fit to reply...

At today's difficulty it would take around 25 terahashes or 25,000 gigahashes to average 1 block a day solo mining.  Around 3600 gigahashes could average 1 block a week.  Around 850 gigahashes to average 1 block a month.  Around 70 gigahashes to average 1 block a year.  All of those numbers are approximations and don't take into account difficulty changes or luck.  They just suggest the average amount of blocks you might expect to discover in that amount of time assuming everything else holds constant.

The network tries to produce one block per 10 minutes. It does this by automatically adjusting how difficult it is to produce blocks.

Anyone experiencing very low reward for last 2 blocks?

I'm making a little less now that the pools gh's are going up. but its not much less.

I was wondering why... stupid gh's Sad and difficulty level predicted in 2 days too...

Yeah and with the price as high as it is i'm sure it will be going up a hell of a lot.

To make solo-mining reasonable you should find at least one block for each difficulty change on average, otherwise you will play catch up with the difficulty, which may never happen.
To get 1 block each 2016 blocks - you should have 1/2016 of the total network power. Now it is 5.2Ph, so you need at least 2.58Th ... You are better with double that, which is easier to calculate as 0.1% = 1/1000 or simply replace Ph with Th ... 5.2Ph => 5.2Th

Just be careful not to sync the file a wrong way. LOL

Also, I have read the other day about a guy whose NAS lost a drive out of a RAID5 array and never notified him something was wrong. When the NAS lost another drive, his data was gone. So, you may want to test that your RAID failure notification is in working order.

Maybe an extra copy of the wallet on a CD-R? That reminds me to make a fresh one today.


dont think it matters if he overwrites a newer wallet with a slightly older one.

I loaded up a copy of a wallet that was a month old, it just churned muchmuch much longer getting itself up to date

Correct. But as long as all receiving addresses were included in that backup. In my case I had a backup from a week ago but it didn't include the newest receiving addresses. Lesson learnt, no more new addresses - ever!

I could be totally off on this, but it seems like I remember reading that the client generates a bunch of addresses the first time it is run even if they aren't all initially displayed in your wallet.  I thought it said you didn't really need to backup the wallet again until you used all of those up.  Just throwing that out there.  I'm sure someone with more knowledge of how the client works will correct me if I'm wrong.  heh..

So my worker status tells me 122 Gh/s yet pool side it's only showing 75. Could this be a pool side error, display error or something to do with my internet connection? I've looked into cgminer screen and ST: 2, so stale shares seem minimal?

I don't get it?

Wait for the round to end. The next one will show your correct hashrate.

Thanks KNK, however I boosted the heat of my machine up to it's 'happy' operating temperature of 68*C (it's a KNC) and hashrate is going up. If my miner status window says 122, and poolside says 75, but when I boost the temp it starts to rise to match, what the hell is going on there? Faulty component? Sorry, don't know much about this ASIC technology, only what I've read on forums and everybody saying the chips don't like the cold weather, which seems spot on? I might go read up on the chip technology being used in my miner...

Don't want to cook the thing!

Thanks Smiley

Current round duration: 10:13:36.  Does everyone in the pool work on the same potential block or while some of us are hashing for 10 hours for .011btc others in the pool are making 0.11 in like an hour?

And what are empty blocks?  Can Slush find ourselves mining an empty block?  How long before it's considered too long to be crunching data, 12 hours, 18 hours? 24 hours?

Yes, I'm actually more into the machinery.  I don't know how mining works but I can change a CP2102 successfully.

okay, everyone on the pool works the same block, infact everyone around the world is trying to mine the same block, until it is found.
What you are seeing is the fact slush's pool has not found a block in about 10hrs, thus the current round duration is high.

A CP2102 is the USB communication IC on a USB Block Erupter.  It's also used by other manufacturers on various electronics.  It can have a high failure rate I think but that may be the skill of the smt machine programmer/operator or lack of.  Replacing manually is very difficult.

11 hours 50 minutes now.  I had assumed a block was an encryption of some bitcoin transactions and its equation produces a result with a leading string of zeros; and that mining was recalculating the block looking for a more elegant solution, a more elegant solution indicated by an increase in the number of leading zeros in the result.

When you say everyone around the world is trying to mine the same block, until it is found, I have to assume you mean everyone in the world in this pool rather than all pools working the same block.

I recall earlier this year there was a string of "empty blocks".  So I assume an "empty block" is block with no transactions but having a result.  I wonder how an "empty block" can be mined.  Does it potentially have a solution that will get paid the 25BTC?  It obviously won't have any transaction fees.

So, if I'm not incorrect, even an empty block can have a more elegant solution.

And when a more elegant solution is produced it's called finding a block.

I saw that blockchain.info pie chart of pools working the blockchain.  That large Unknown percentage, I recall a global Chinese gambling syndicate got into mining and had on order a great many miners a few months ago.  If any pool is going to find a way to game the system, it would be it.

Sorry TL;DR the rest, No EVERYONE is trying to find the block, the finder gets the block, then everyone starts trying to find the next block. when i say everyone i mean everyone. slush has not found a block in 12hours. roughly every 7-10mins a block is found, so this means every 7-10mins EVERYONE starts working trying to find a new block.
