Thanks man
I think that big hasher is on more than 1 pool, most of the time ~5Th but he went big for a few days last week then backed off

I did too - only BTCGuild and Ozcoin saw a significant increase in network share this week. Nice going, Graet! I also found this interesting (note that Ozcoin has the third highest hashrate miner on the chart):

Thanks again ooc

I find interesting

Ah good. I mean, not good, but at least the result ties with my estimate. Phew!

I guess even a pool that has the lion's share of the network will experience bad luck from time to time.

The luck was obscenely bad this week for BTC Guild, especially the last 24 hours.  We had a bad run at the start of the week, a good run in the middle, but the last 24 hours have been some of the most brutal rounds we've had in a long time (back to back 1.5-2 hour blocks for most of the day).

And indeed they have.

I was still sick and off work for the last week, so again I'll keep this intro short.

1. BTCGuild luck (again)
BTCGuild's luck this week is again unusual. Again I audited the script and looked for any tiny error in the way I estimate luck for BTCGuild, but I couldn't find any error. Either the luck this week for BTCGuild was unusually pool, or the procedure I use to estimate shares per round is insufficiently accurate. I'll see how it goes next week.

As usual, please post comments if there's anything you don't understand, with which you disagree, or just think is wrong.

Yes, eleuthria's right.

However bitfury has granted me access to ghash.io's pool stats and "unknown" should return to it's previous low levels.

Not very hidden.  Most of that speed is ghash.io, BitFury's solo mining operation.  http://blockorigin.pfoe.be shows the actual unknown part of the network is still extremely small (~3%).

unknown's share continue to increase.  some hidden mining entity?

I've been sick this week, so this introduction will be shorter than usual. Hopefully I'll have some interesting new posts once I get over this bug.

1. BTCGuild luck
So there was a problem in the way I'd been calculating BTCGuild luck since around March. I fixed the error I found and the result for this week is much more normal.

2. The Google "+ 1" button
Thanks to everyone who "Plus 1"'d the post. I hope I'll be able to use the "plus 1"s to judge which posts get traction (and are the sort of thing you find interesting) and which are not.

1. Deepbit is at 0.29% of the network
Only a year ago Deepbit was one of the top hashrate pools with 20% of the network. 18 months ago it was at 30% of the network. Now it is one hundredth the size at 0.29% of the network. The are many reasons for this drop, but I think the main thing for pool operators to keep in mind is to constantly innovate, keep ahead of the competition, and only use a non-exploitable reward method.


2. bghash.io
I turns out that the entity that had been signing "bghash.io" in the coinbase and paying out to 1CjPR7Z5ZSyWk6WtXvSFgkptmpoi4UM9BC is none other than bitfury's private pool, GHash.io. Bitfury is a manufacturer of ASIC mining devices, and if this pool is his test bed it's been running at 83 Thps for the last day or so (according to his website). I'll be contacting Bitfury to see if he'll give me access to any data for the weekly pool stats. The recent increase in the number of unknown blocks solved is mainly attributable to this pool - it has around 18% of the network at the moment.

3. 1360 blocks solved by the network this week.
Up from 1320 last week - the network's hashrate continues to rise exponentially without break, as it has for the last month (see the log-linear chart, figure 2). This is not a good time to have invested in mining hardware.

Last week I estimated we see an average network hashrate of 500 Thps this week. At 490 Thps, we're almost there.


4. BTCGuild luck
BTCGuild had enormous luck yet again this week, with a CDF of 0.00. I have to derive the data in an unusual way for BTCGuild, so I'm a bit concerned that this luck may be incorrect. Indeed, if you look at Figure 5 for BTCGuild, you'll see that recently the CDF's have been grouped at very high or very low values. If I find some time I'll try to figure out why.


5. The Google "+ 1" button
The best form of feedback I get about the posts I make is from the "+ 1" button clicks at the bottom of each post. The more "+ 1" a post gets the more likely I am to post something about that in future - not much point taking the time to publish something no one finds useful or interesting. So if you find a post you like, please hit the "+ 1". The more "+ 1" a post gets, the more likely you'll see something similar in future.

As usual, please post comments if there's anything you don't understand, with which you disagree, or just think is wrong.

1. bghash.io
The entity signing "bghash.io" in the coinbase has stopped adding that signature since last week. They still seem to mining, as their payout address shows:
1CjPR7Z5ZSyWk6WtXvSFgkptmpoi4UM9BC
The current blocks belonging to them no longer hasve coinbases signed with an obvious unique identifier.
2. 1320 blocks solved by the network this week.
No sign of the network hashrate slowing any time soon. Even with some reduction in the increase of additional hashing sources, the network could be at 500 Thps by next week -  and at that rate, 1 Phps in 4 to 6 weeks.

3. BTCGuild luck
BTCGuild had enormous luck this week, with a CDF of 0.02. This is about a once in a year event, so I hope the BTCGuild miners enjoyed it.

I do a percentage of network of time chart weekly, going back to early last year.

Blockchain.info has nice pie charts but I would love to see something showing the % over time.

Changelog:

    Gigavps' Semi-private pool added (thanks for the help, gigavps)

Usual pools missing from results:

    Maxbtc - planned closure.
    Coinotron - planned closure.
    Bitcoinpool - Website down and as far as I know no blocks solved since May. I'm assuming they are closed.

Errors:

    Blockexplorer.com hasn't updated since block height 250458. Since I use Blockexplorer.com for the network's hashrate every 144 blocks, that statistic is incomplete this week. The weekly average hashrate, blocks solved and so on I calculate using my own data so that is unaffected.

    Bitparking: "bitparking"
    BitMinter:  "BitMinter"

    Slush's pool: "slush"
    ST Mining Corp: "st mining corp"
    There's a new coinbase signature I noticed:  "bghash.io". Does anyone know if this is a pool's name or just the name of the pool's software? The following blocks were solved by this entity:

        250205 250226 250329 250354 250393 250433 250486

and the generated coin was paid to this address:

        1CjPR7Z5ZSyWk6WtXvSFgkptmpoi4UM9BC

which has been actively solving blocks since the 6th July.

Pool hopping:

    Nil.

1. Unknown hashing sources at 1.9% of network

Blocks solved by unknown  sources are now down to 1.9% - that's only 25 blocks out of a total of 1323 for this week. That total is 31.25% more than it should be, so I don't see the skyrocketing network hashrate start slowing down anytime soon - especially with all the new sources of hashes recently available.

2. Gigavps' Semi-private pool

I added Gigavps' Semi-private pool this week, starting on the charts with a massive 7% of the network. Interestingly, Figure 8 shows the pool has a much higher minimum hashrate than for other pools. Specifically, the minimum hashrate is ~7Ghps, and the top four user accounts have between 1.2 and 7.8 Thps. This is an all-ASIC pool (or at least very close to it). I think most pools hashrate distributions will look similar to that in the future.

3. Lest we forget

Also this week we say farewell to Coinotron's BTC pool and MaxBTC, both in a planned closure. Coinotron seems to want to focus on alt-coins, and MaxBTC's pool op will concentrate on Kraken.com, a very nice trading platform - give it a try, if you trade. ABCPool.com  has also closed but being a proxy pool they were not included in the weekly statistics.

Bitcoinpool.com is still offline with a 404 error from an nginx server somewhere. They haven't solved a block since May, so I think they won't be back.

In honour of the pools that have gone to the God of the Blocks' happy hashing grounds, I've produced a chart of the percentage of hashrates of all the dead pools for which I have records, in order of the last week in which they solved a block.

I'll update the chart when the next sad occasion arises - which I think will be when BTCDig.com arises phoenix-like from the ashes of btcmine.com, or perhaps it will be Bitclockers.com, which have had payment and website issues recently and today were down to a total pool hashrate of 1 Ghps.

So, with sadness and nostalgia I present the Dead Pools.

Please take some time to think about the pool operators who ran these pools, loved them as if they were their own children, and did their part to help secure the network. Also, don't forget about the many other pools that didn't make it -  Arsbitcoin and Continuum pool (the first pool to use the Geometric method of reward distribution, the progenitor of DGM) come to mind, but there have been many others, especially those that were unable to change from a proportional reward method.

There are lots of new ASIC miners around, and if you're not tied to any particular pool already I have a suggestion. Look at chart 8, which show the user hashrate distribution for each pool. Look for pools with the largest density of user accounts above 50 to 100 Ghps - those will be the pools that have happy ASIC owners and few GPU owners. If they are small pools, why not give them a try? Ozcoin and HHTT are the pools with the largest number of ASIC users at the moment.

Also, congrats to p2Pool - really picking up steam. The ASIC problems there must have been solved.

Finally, anyone else noticed that the network hashrate has increased exponentially (linearly on the exponential scale) since February this year. Why could that possibly be, Avalon? Anyone game to guess when the increase will revert to linear?
