Thought I would share this for those that try to understand Kano pools accounting and why some of us like it.

I downloaded my bitcoin transactions and ran a simple spread sheet calculation.

I currently run 2 S9 miners, one of which is only operating at 2/3 as one of its hashing boards is not working.

That gives me a hashing number of  13.6 + 9.2 or 22.8TH/s

For the last 14 days the average total payout per day is 0.007548879285714 bitcoin

each individual payment is between .0039 and .0035 bitcoin

On some days I get 1, or 2, or 3 or maybe even 4 payments. On some days I may get no payments, depending on if the pool finds a block.

The reason the payments vary is due to Kano including the transaction fees collected for block creation and those transaction fees change depending on
factors outside of Kano's control. The blocks found can vary between 12.5 up to and even past 16 bitcoin.
Most "other" poos, er pools, keep that 0 to 3.5 bitcoin but Kano passes it on to us!

The average payment is higher than I would receive for any other pool currently operating.

This is why I stay with Kano.

If you get on Kano pool and mine it for a day or two there is a chance you will not receive any payments or a very low payment. This is due to the payments being divided into 5 roughly equal parts, that are then paid out over 5 payments. Once you have been mining long enough for 5 payments to have happened you will start to see the full amount of your mining on every payment. Payments happen when blocks are found, this means you may see payments right away, or may not see any in a 2 day period. I have seen kano pool find no blocks for over 48 hours and find 4 blocks in 12 hours. Kano provides extensive information on his web page showing what is happening.

Why am I promoting kano pool? Well, the more people that mine here the greater total hashing power. The greater hashing power the more blocks will be found. The more blocks found will keep payments flowing more regularly. I won't make any more money, since with more total hashing power you pay out to more people, but it would provide a more consistent flow of money.

If you wonder what I meant by more hashing power means more people but the same payout for me, look at it this way.  If kano pool has 80PH/s each of my payouts is as stated above, about .0036-.0037. If hashing increased to 160PH/s, then my payouts would drop by about half, but I would get twice as many payouts in the same amount of time. This is because my percentage of hashing is not going to change, unless I buy more equipment. That means my percentage of hashing between a pool total of 80PH/s and 160PH/s would drop by about half, but, we would find more blocks, so I would get the same amount in the end.

I guess Kano would make more money, assuming he would not need to invest in more equipment and fixed costs to support a larger hashing base. I see that as a good thing because I like the way Kano does business.

Hello,
I just recently tried to purchase an A741 and controller from the canaan website.
They do not seem to have any kind of automated payment set up.
I sent a request into their support via a ticket, as it seemed to indicate to do.
Does anyone have any past experience they can give me that might help?

Has anyone else noticed the Banned peers list getting really large in their bitcoin core wallet/full node?

I had a S9 hashing board die on me. I checked with bitmain warranty , (it is out of warranty), and they said a new hashing board would cost me $600.00 not counting shipping. Since a brand new S9 costs a little under 1100 I politely declined.

Then I thought.

I have 3 S7LNs I am not running due to it being the middle of summer and not wanting to pay for their not very efficient mining and air conditioning at the same time.

So, how about removing the S7 hashing boards and the S7 controller from the S7LN and replacing them with the two remaining good S9 hashing boards and the S9 controller. That would free up a APW3 and use a bit less wattage until I can get a new S9 from bitmain.

I also would not have to finangle a 220 volt line as the S7LN built in power supply uses 110 volts.

Has anyone done this already?

dzimmerm

Drat,

One of my hashing boards on my older of two S9's is not working. I am getting about 9T-Hash/sec on that S9.
Has anyone worked with Bitmain to get a replacement hashing board? It is out of warranty so I will have to either run at 2/3rds or try the not very happy arena of ebay if Bitmain can not get me a replacement.

I have put in a repair request asking that question of bitmain but would appreciate any knowledge of past experience others have had with them.

Meark,

I started mining with a little dinky antminer U3  that cost about $25. Bitcoin was valued at $237 at that time. I ran the antminer off my main computer and I think I used bgminer software. I seem to recall using Elgius pool and several others to try out the concept. 

After I confirmed you really could get bitcoin dust out of such things I looked around and settled on bitmain's S7. The S7 and associated bitmain power supply cost me 2.133 bitcoin. The cost in dollars was $720 (1.649BTC) for the S7 , $140 (0.321 BTC) for the APW3 power supply, and .163 bitcoin for fedex. Bitmain only accepted bitcoin for purchases of antminers.  After that I used the bitcoin produced by the S7 to purchase a S7LN, then used the bitcoin produced by those to purchase a second then a third S7LN. The S9 was purchased by bitcoin produced by the 4 miners plus the rapid rise in bitcoin value. I then purchased 2 power supplies and waited until I had enough bitcoin to purchase a second S9. I do not run the S7s at this time due to it being summer and I am already paying heavily for keeping the house air conditioned. I may use them when it gets cold in the fall, but mainly to purchase more S9s. The goal is to supplement my retirement income so I can retire at 62 in 2018.  10 S9s would make a healthy income for a frugal family. Planning will need to be done if "Mr Fusion" is not available in the next year or two. 10 S9s would use 15000 watts of power, which at 220 volts is about 68.2 amps. That is doable with house wiring capable of 200 amp, which most are.

In case you have noticed my initial investment was under $1000. Investment after that was me paying for electricity out of my day job so the more rare bitcoin could be kept to purchase more miners. Bitmain also is a bit slow on production, doubtless because they are using most of their product for themselves on their farm. You have to check Bitmain's website often to get a chance to purchase a S9.

Hope this info was helpful in some way.

Yes, two reasons.
Kano shares the transaction fees received when a block is mined as well as the 12.5 bitcoins . This results in blocks with values between 12.5 to 16.5 bitcoins.
Secondly Kano charges a smaller fee, .9%, on the miners earnings.
All of the large pools keep the transaction fees. Slush and Kano, both medium sized pools, share the transaction fees with their miners. Some smaller pools share transaction fees, some don't.

The only pseudo drawback to Kano is that it sometimes goes a day or almost two without hitting a block. That can be discouraging if you are a newbie. Kano also splits the payouts so they are about 20% of value earned divvied up over 5 payments. This is done to smooth out payments even if the input of blocks is very irregular. It means you will receive smaller more numerous payouts untill you have been mining for about 4 or 5 days. After that ramp up time you will receive numerous full payouts. My current payout with two S9s is a bit over .005 per payout. What varies is the number of these payouts I see per day. If averages hold that would mean I will receive .013 bitcoin or better per day for 2 S9s.
I added the second S9 less than a month ago so I can not give you hard figures yet.

Kano pool requires a bit more patience due to the 20% payout system and its some what irregular block find timing. I would strongly recommend committing to Kano pool for no less than 2 weeks and then you will see for yourself how much more you are receiving compared to other pools.

I did a months check when I was running one S9 and the daily payout averaged to about .0065 bitcoin a day.
This will vary depending on luck, but probably not by much.
Whether it is worth it or not depends on your electricity costs and the value of bitcoin at the time.
For me it is a positive amount unless the value of bitcoin drops very very low.

My second S9 finally came! It is now added to the first S9 on Kano's pool.
Another reason to do a happy dance on Friday.
Now to save up for my third S9.....
Have a great weekend everyone.

When in doubt, get an inexpensive digital volt meter. Harbor Freight has them for 3 or 4 dollars. Measure across the poles you are planning on wiring up. If you get 220 or close to it then you know you have the right setup. My breaker box has the old "pushmatic" breakers. The configuration on my breaker box has the power from the electrical meter going to the two main breakers in a doublebreaker configuration at the top of the box. Those two main breakers each feed a separate power bar. You can draw 110 off of either of the two bars via pushmatic breakers attached to each bar. To draw 220 you have a doublebreaker just like the Main breakers. You tap off of both sides of the double breakers to get a properly breakered 220 volt line, often used for electric clothes dryers and whole house air conditioners. As stated earlier it is wise to use wiring and outlets made to fit 220 volt appliances so you cannot accidentally plug an 110 volt appliance into a 220 volt connection. The power cord for the miner power supply will probably need to be customized to fit the 220 volt outlet while maintaining the connector that fits into the power supply, which is the same for both 110 and 220 volt power supplies, at least in the USA. If you are not familiar with house wiring then it is wise to get the help of an electrician. There may be codes that require certain electrical boxes to be used when adding a circuit. I typically use metal junction boxes with a properly grounded safety ground going to the ground , not neutral, connections in the breaker box. Some cities have other ideas about what is safe, but I prefer a junction box that will not burn and is grounded so any short circuit will trip the breaker as it is supposed to.

I have been using DHL when ordering from Bitmain and they seem to do a fairly decent job.

I agree that the pools are somehow like banks now.

Perhaps you should consider not how many bitcoin are being produced but their value in dollars. If the price of bitcoin continues to rise then continuing to mine profitably should not be an issue.

I have a couple of questions.

1) How to configure my p2pool node as a full node that accepts incoming miners and properly reimburses them?

2) What in the HE double tooth pics happened between p2pool.in and p2pool.org? There seems to be something weird that happened and no search I have done on google or bitcointalk seems to provide any history or background. I went with the information provided by p2pool.org when I noticed the p2pool.in stats page appears to have stopped working sometime in 2015 between January and March. Being as it is now January 2017 it appears that p2pool.in was no longer providing network stats. Further research shows that p2pool.in was merged into p2pool.org's info when the GIT repository was changed from p2pool/forestv to p2pool/p2pool . Unfortunately there are still several places where there are dire warnings about using p2pool.org verses p2pool.in on various webpages and even on the old GIT for forestv. I heard references that forestv had taken a leave due to personal issues but I have not seen any official retraction stating that p2pool.org is ok to use.

The confusion surrounding question 2 needs to be addressed as I am thinking it is blocking many miners from choosing to go with p2pool in any form. Contradictory information often does not lead to wrong action, it leads to no action.

If this is too personal or touchy a subject then please email me with a response at dzimmerm56"at"g m a i l . c o m. (you will need to intelligently fix the addy, but I know all of you are intelligent)

If you have your local p2pool-16.0:python console up you can see transactions happening and such. I run the p2pool node on linux and I keep the console up so I can make sure things are actually happening. It also gives local information on hash rate, (as it is scrolling past).

Not sure how this would work in windows or mac though.

I also see a Dain 0.0.1 node connected to my node.

From my debug Peers screen on my Satoshi .12.1 client/node

(edit)
I just noticed that version 70002 is probably Satoshi:0.11.0 , so I am guessing someone changed the client's name before compiling.

So this person is running an old Satoshi client.

Is there anywhere to look for command line options for BFGminer that are not specified in the help file documentation?

I am using the, as far as I can tell, undocument #skipcbcheck command and I am curious if there is a command to skip the [blktmp error: Unrecognized block version, and not allowed to reduce or force it] error. I am using bfgminer to mine for UNIT / UniversalCurrency on the SecurePayment.cc website and have managed to mine 2 blocks so far. I just upgraded to 5.4.2 to see if that changed the error and it did not.

I have looked over the documentation that comes with bfgminer as well as its -h option from a terminal and can not find a command to do what I want.

I realize that the miner is aimed at bitcoin so I understand if there no way to turn off the error. I was hoping to find out for sure though.

I just updated my openSuse 13.2 workstation to bfgminer 5.4.2 from 5.4.1. It was really painless so I wanted to pass on what I did and a little of why I did it.

If this is your first time installing bfgminer then you will need to verify you have the various dependencies installed as well as a working development environment. This includes having an up to date compiler. If you do not know what I just said then you need to do some research that is beyond this little quickie help post.  

As a regular user, no root or sudo, or su at this point.

Download bfgminer-5.4.2.txz and copy it to a folder of your choice. I put mine in a bfgminer folder in my home folder.

Use ARK or some other archive program to extract it.

open a terminal and go to the folder that was created during the extraction, /home/(your user name)/(bfgminer or other)/bfgminer-5.4.2

run ./configure    (as regular user)
run make           (as regular user
open a su session
make install       (as su root)  (this installs the executable in the  /usr/local/bin folder, and makes it easy to upgrade from previous versions as all your shortcuts will point to the correct place)

I use bfgminer to run a little antminer U3, mostly to test pools and ports for possible mining with other faster ASIC miners.

If you are mining coins other than bitcoin you will likely need to append #skipcbcheck to the end of your pool URL as bfgminer wants to see a bitcoin coinbase and labels your pool as misbehaving.

Example for UNIT or UniversalCurrency

/usr/local/bin/bfgminer -S antminer:/dev/ttyUSB0 --set antminer:voltage=x790 --set antminer:clock=x0D83 -o stratum+tcp://universalcurrency.securepayment.cc:3377#skipcbcheck -u (yourreceivepaymentaddress) -p (your choice)

I have used the bfgminer and the antimer U3 to mine titcoin, digibyte, and UNIT(UniversalCurrency) altcoins as well as bitcoin.
