I'm looking for a probability calculation that would let me calculate the odds for finding a block at a given hash rate and a given difficulty (or current difficulty) . Does such a thing exist?

I'm considering purchasing a mining contract for a solo pool (been running one here for the last month and doing OK) so I want to know what level of mining capability will bring me (statistically) a btc block.

Thanks for any info!

That will be like playing the lottery 100Th if you are very lucky around 19 days. Part of my hash are on a smaller pool 164 TH and we are 128 hours in. Stay with a pool. especially if you are going to rent hash.

As a rule of thumb, for a solo mining to be reasonable, you need at least 1/2016 of the network hashrate, because you need to able to find at least 1 block each difficulty change (assuming 100% luck).
Otherwise you will be playing a catchup with the difficulty.

You can directly use the network hashrate from https://bitcoinwisdom.com/bitcoin/difficulty and compare it to your hashrate. Your percentage of the network is your chance of finding a block

Another way to calculate it is to comapre network diff to the number of diff 1 shares your hardware can provide instead. Network diff aims for 1 block each 10min, so your chance to find a block is the number of diff 1 shares you can provide for the same period vs network diff.
4.295GH/s = 1 share per second
1GH/s is approximately 140 shares per 10 min
10GH/s ~= 1397
100GH/s ~= 13970
1TH/s ~= 139700

Example:
 Network diff now is 39457671307
 Your hashrate is 3.5TH/s ~= 488950 diff 1 shares each 10 min
 Your chance to find a block is 488950/39457671307*100 = 0,00123917601775%
 To find a block before diff change 2016*0,00123917601775 = 2,49817885179%

Can I ask why has the old site stats page changed? The columns/data for Your Shares and Your BTC Reward seem to have been removed.

I was sure that I read that no changes would be made to the old site (https://mining.bitcoin.cz/stats/) as many people said they wanted to stick with using that site.

I am in the middle of running my own pool comparison and so I have a spread sheet of all blocks found at each site and my reward for each of those blocks. All of the pools I have run this test on publish different pool stats, but the one common thing published by all pools is your reward per block (it's kinda the most important piece of information) so why has Slush removed this?

I know the new site shows the block rewards, but the stats info is different so would require a new set of columns in my spread sheet and thus means that I would not have continuous data throughout my (2 months and counting) test. Any chance someone could look at the old site and re-instate the missing columns please?

Dazed and Confused

Alright.

Thanks, Billbags.

Just wanted to make sure!!!

It's 5:15am here.  I've been up all night looking at exhaust fans online.  Gotta get some sleep now.

Huh I just checked and they are still there on mine.  You are looking at the Statistics page, and not the My Account page, aren't you?

Sweet! I've only found one block (269489) about a year ago on Slush's pool and that was with a few Block Erupters! Times sure have changed since then  Wink

Thanks for the reply, but please ignore my last post - total brainfart on my part!  Roll Eyes

It was because I had been logged out of both the new and old sites when I did an F5. It happened at the same time and is strange because I have not logged out/in to either for weeks as the PC is on all the time and the browser window is always on the pool stats pages. Oh well, I'll know next time  Grin

LOL   Grin Grin Grin

If you were to see what I'm up to you would understand, Sir Alan.

Two pics and you'll understand:

My rigs in an existing closet [18.5 Th/s; over clocked just a wee little bit]:





The new mining closet I'm building still needs a bit more work (caulking, priming, painting, finish electrical, add an exhaust fan, add an exhaust duct with damper to the outside through the window in the closet, weather stripping around all of the doors, etc.  As for the size of this thing: it's big enough to easily hold 96 S4's.  It has two 36 inch doors on each side to have easy access to the front of the rigs.  Each door will have four (4) 25"(w) x 14"(h) grilles to allow a 12,000 CFM to 18,410 CFM exhaust fan to easily pull air into the rigs intake, through the outtake fans into the closet and out of the exhaust fan to the back yard.  One of the doors has four (4) grilles already.  I'm installing the grilles only as needed.  I only need one door with grilles at the moment.  More grilles will be added as rigs are added.  The center door in the front is for access to the switch, router, PDU's, fan, the rear of the rigs, etc.




25.5 Th/s will be added to this in March for a total of 44 Th/s.  The goal is 200 Th/s by the end of 2015!

These guys are doing something similar to what I'm doing but in a POD.  They are pulling the air in through filtered grilles with three (3) 6500 CFM fans to cool the rigs but more high dollar elaborate:

http://www.cryptokube.com/

Youtube video of what they are doing:

https://www.youtube.com/watch?v=5bDtgIcVb3s

I have a window in the back center of this new closet.  It is 32"(w) x 36"(h).  This new closet is 8'(w) x 8'(d) x 7'(h) = 448 Cubic Feet.  I'm presently eye-balling a 30 inch single phase 120/240 Volt 12,000 Cubic Feet per Minute (CFM) exhaust fan:

http://www.h-mac.com/tpi-mcd30-112.html

I'm also eye-balling two different 30 inch single phase 240 Volt 18,410 CFM exhaust fans:

which avalon and is it configured to use slush pool? please add more information about your case.

You can contact me through tawk.to through here
If need to verify identity ask for a signed message from https://keybase.io/reynaldo , I'll never discuss details through tawk.to that involve addresses!

Who cares, at 500 each with shipping included it's a pretty good deal. Keep 1 and sell the other.
