Topic: Weekly pool and network statistics - page 16. (Read 91451 times)

This should help miners get a better idea of the hashrates at for pools at which they might want to mine. I'll be updating this weekly here, and also in the thread so there's a history. If you'd like anything else, let me know.

If your pool isn't here and you'd like it to be, PM me with a link to a block history with round lengths and either solve times to the nearest second or a timestamp.

This week I want to point out Slush's pool's consistency in terms of proportion of the network. It has been at around 10% of the network hashrate for well over a year now - consistency unmatched by any other pool. Well done Slush!

Silent achievers Ozcoin, Eligius and EclipseMC have both been increasing their share of the network consistently for the past couple of months, and BTCGuild's share of the network is once again on the rise. Oh no, the sky is falling! etc.

Is ASICMiner renting hashes to DiscusFish?
This week I noticed something quite odd. If you scroll down to Figure 3 and compare the two yellow lines, you'll notice they look quite similar. The lines are for ASICMiner and DiscusFish. Here's a second chart comparing their block solved per week:

#### see blog for chart ####

The relationship between the two is really quite suggestive. Taking variance into account, it does seem that DiscusFish and ASICMiner solo started signing the coinbase at about the same time and have been increasing their hashrates by about the same percentage rate.

Here's a correlation plot:

#### see blog for chart ####

The linear model statistics:

#### see blog for table ####

I had a quick google but couldn't find any posts that described a working relationship between the two. So, can anyone tell me if it there is a known relationship between ASICMiner and DiscusFish? Has ASICMiner been renting hashes to DiscusFish and if so is it being paid to investors?

Polmine's ASICs are mostly blades, and HHTT user's are mostly ASICs.
In Figure 8, most pools show a bulge around the 65 Ghps mark - lots of single Avalons. Two pools are unusual in that they don't: Polmine has had a bulge around 10 Ghps for the last few weeks, which might indicate a large number of ASICMiner blades. HHTT shows little variation overall, showing a very high percentage of ASIC hashes.

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

The might have been some pool hopping at Deepbit earlier in the week. It might just be coincidence though.

The network solved 1092 blocks solved in the past week - 60 less than last week. I don't think this indicates any significant slowing of the network hashrate though.

Eclipse had a large hashrate boost this week. Unfortunately, I don't have access to a user hashrate API for this pool, but I'm guessing that a large number of high hashrate ASICs joined up. Polmine has an interesting change to their user hashrate distribution. In figure 8 there is a large bugle forming around the 10 Ghps area - perhaps a number of single blades added?

Figure 4 shows Bitminter, Eligius, Itzod and Slush all saw constant gains in hashrate during the week; Deepbit's hashrate gradually declined.

The network hashrate is increasing, with 1157 blocks solved in the past week. The network does not appear to be slowing any time soon.

BTCGuild still has the highest hashrate of all recorded pools, but due to some bad luck this week solved fewer blocks than ASICMiner - now the second highest hashrate entity. Either way, 50BTC.com has dropped to third highest hashrate.

HHTT got another big hashrate boost this week - the top hasher there has 700Ghps. It seems to be mainly an ASIC pool.

Another 10 Thps increase in the average weekly network hashrate this week. I fear my batch#2 Avalon  may come too late to pay for itself in BTC - the "View Order" page is still empty.

Thank you to all who completed the survey (mentioned last week and introduced in this post). I've had 135 responses so far, which is fantastic, and I'll leave it up for a while yet. Thanks also go to DrHaribo of BitMinter who posted links to it in various social media.

BTCGuild is now down to 23% of network blocks, and 50BTC.com and ASICMiner up to 20% of network blocks. Nice healthy competition between 50BTC.com and BTCGuild. As for ASICMiner, where will the meteoric rise in hashrate end?

A huge 25 Thps increase in the average weekly network hashrate this week - that's about a 25% increase in one week, of the weekly average. This hasn't happened since the first batch of Avalons were released combined with the start of the last btc price bubble.

Since it will be mostly miners reading this, I'd like to invite you to complete a survey I introduced in this post on the cost of mining. It will be a huge benefit when it comes to fighting FUD form news outlets looking for a suitably scary news story to demonise bitcoin.

Thanks for the explanation doublec.


Good idea - if you have the data (raw hex coinbase), I can write a script. I'm not keen to run four different bitcoind equivalents on my laptop!

The coinbase is usually a giveaway. If it contains a bunch of junk or the string 'mm' is inserted by some software:


The coinbase in devcoin for a lot of the blocks are:

They have the majority hash rate on ixcoin and devcoin.

Sometimes it's hard to tell. For example, Eligius still has the MM coinbase but they say they announced they no longer offer merge mining of namecoins to miners so presumably they haven't updated their coinbase for the removal.

Software to analyse bitcoin blocks and the associated blocks on the altchains would be useful.

Well spotted!

I'll combine their data before next weekend.


I read somewhere that you can tell which blocks were merge mined, but never got around to looking closely. How do you tell?

They're also merge mining namecoin, ixcoin and devcoin for the curious.

Thanks:
Pool ops kinlo (Triplemining) and DrHaribo (Bitminter) for helping me figure out how to get the coinbase of each block without having to hammer blockexplorer.com too much. kinlo actually wrote me a bitcoind patch which I'm sure would have been very helpful if I had been able to compile bitcoind from source on my old macbook pro linux linux machine, which for some reason I can't.

Many pools had bad luck this week. This may have been due to a problem with getblocktemplate, which seems to have slowed many pools down until a patch was made available earlier in the week.

BTCGuild solved a comfortable 32.2% of blocks this week, so there are already calls for the PPS rate to be reduced. I doubt that will happen any time soon - BTCGuild could easily pop the 40% barrier if all the PPS miners returned.

ASICMiner's solomining has been added as a pool from this week on. Don't forget they have some hashaes at BitMinter and BTCGuild - only the solomined blocks show up on the tables and charts.

BTCGuild solved about 39.1% of the network's blocks this week. It seems that eleuthria's choice to increase PPS fees at BTCGuild and no more increase in hashrate from ASICMiner has resulted in a stable percentage of the network for BTCGuild. There was a large drop in the pool's hashrate this week (see figure 4) which I think is from ASICMiner pulling 4Thps from the pool.

Not that it means anything, but Itzod was by far the luckiest pool this week (CDF 0.05), and Slushes pool the unluckiest (CDF 0.99).

I'm not going to comment any further about this week's stats - I still have to post the weekly network forecast and forum member Kano made an interesting suggestion that I need to follow up.

Argh! Can't be a second late! Well, 24 hours late, anyway

Mother's Day dinner yesterday, and then for some reason my script is doing weird things with Ozcoin's data, so I had to wait til I got home after work today.

Anyway, just finished the post: http://organofcorti.blogspot.com/2013/05/12th-may-2013-weekly-pool-and-network.html

I'll update this thread and the "Mining Pools list" sticky shortly.

Probably none. DeepBit's results on chart 7 are a bit suggestive, but nothing significant.

Ozcoin closed for a few days this week so that pool op Graet could be absolutely certain that the pool was working as it should. If any readers out there want to run a pool, then this is the example you should be following. If my Avalon had been delivered I'd be including Ozcoin in my group of pools.

Another hack attempt - BTCGuild pool op eleuthria reported to his miners that persons had attempted and failed to gain access to a BTCGuild server using social engineering techniques. He warned his miners about his as soon as it happened. He also put the pool's PPS fee up to 7.5% to attempt to mitigate the large share of the network the pool has - however this hasn't stopped BTCGuild's growth completely, with 41.0% of the network's blocks solved by BTCGuild this week.

Finally, there's a concern that BitMinter was having unusually poor luck for the past few weeks. I've performed an audit for pool op DrHaribo, and have found nothing unusual at all - so if you were worried about mining at BitMinter, you need worry no more. I'll post the results as soon as I'm able.

You made intentions known a long time ago - good move since miners need a loooong time to make changes. For a high tech cutting edge crowd we seem preety conservative in some ways.


I'm planning to include an eCDF and a fit to a (probably) pareto distribution. It'll be interesting to track the changes to the variables over time.
