thx jb, i was thinking to do something about like windpath for the block history. but it's too much work. but happy with what is being shown atm at my pool. btw, is there a way to ban/kick someone/ip from mining at my pool ? there's an address with a incomplete btc address mining with very low hashrate & pool does not show it's share difficulty & time to share.  and another block today ... hope p2pool will keep it up  If it's an invalid BTC address, then if and when that miner finds a share, it'll be a donation to you. Whatever address your p2pool node uses as its default payout address will be the one that gets any credit for shares from invalid addresses. So, I suppose you could just let whoever it is mine away and thank them for the donation  |

Congrats to the lucky winner!!! Block is confirmed  |

Thank you. You may have saved my marriage...  LOL... you think the S5 is loud, you should have heard the Spondoolies SP10... good lord that thing screamed. |

this is the list starting with the original 10 note that the btc addy you give for winnings deposit must match the btc addy in your profile
Just prettying up the formatting for the list... also added TAK's user ID to his link |

I think the only way this would work would be if implemented in cheap electronics and letting the customers in the dark about the additional power draw. I mean if they claim it will use X watt then they might not have to tell the customer that they will draw that all the time. So customers think they buy cheap while in fact they buy for way more.
Seeing that business model... i cant imagine that enough investors believed this. Maybe they were noobs and never heard of difficulty. Miners work for the first month, second a little bit and thats it. If a miner doesnt sell in the first month then its hard to get a profit at all. So i dont see an incentive for any hardware producer and i cant imagine that this will work.
Could they have faked the donation height? Did they promise world domination over bitcoin? You know, these devices have to be run through a pool 21 controls, otherwise they are useless.
This makes no sense at all. And i doubt they are magicians that found a way nobody else thought about.
I don't think they are magicians, but the idea certainly has merit. I don't buy the "miner in a phone" argument, simply because of the detrimental effect of constant power draw on your battery. However, for always-on devices like your cable box, your refrigerator, etc, embedding a chip or two is not a stretch. In the IoT world, you've got virtually every device connected and talking. Let's say a chip is produced that can mine at 10GH/s for 3W. That's not too far a stretch from where we are now. Throw 10 of those chips in your cable box and it's only throwing off an extra 30W of heat. At current difficulty, that's $7.35 a month, and at $0.10 per kWh, it'll cost you an extra $2.19 a month in electricity. Obviously my calculations are based on the BTC world as it exists today. You suddenly throw chips into every device and the network difficulty is going to go up. Unless the price of BTC goes up with it, which historically hasn't happened, those embedded chips are going to cost you more to run than they will make. Add into this the upcoming reward halving next year and suddenly things are even more ugly. So... while I do think the idea of embedded chips in the IoT world has merit, the practical application of such is a far-fetched pipe dream. |

Yes... quite a few people have done this. Take a look around and you'll find a few posts describing how it's done.

Hello everyone,
I am new to bitcoin mining and I have a question that hopefully you will be able to answer.
I am currently looking into ASIC Miner but I decided to try out mining software on my laptop first. I know this is not recommended but I am simply testing things out before I purchase a miner.
My laptop has an NVIDIA GeForce GT 650M with 1 GB of GDDR5 SDRAM card and I am using MultiMiner as my software. When I first ran the program I was getting about 38Mh/s, now it dropped to ~600Kh/s
My question is why the huge drop? Could it be the heat?
What coin are you trying to mine? Did multi miner drop your GPU and is only mining CPU? |

how can big PPS pools stay alive...But I'm new to this world, and I have some naivety to wear off.
They can't, not indefinitely anyway. All PPS pools either go bankrupt or change their payout method to stay viable. It has happened over and over. The same will eventually happen to f2pool too. It's a reason why PPS pools charge a fee to miners - to try and help offset the statistical variance the pool is subject to. I'm pretty sure I read a post on here not too long ago that gave the odds... and those odds are pretty dismal looking if you're a pool owner. Something like you needed to have at least 1500 BTC in a reserve to have a tiny chance of avoiding going broke if you're a PPS pool charging 5% fees. Ahh... here's that post: https://bitcointalk.org/index.php?topic=854368.msg11149806#msg11149806The referenced paper by Meni in that post is a great read. |

and they pay just 0.3 USD per 1 kWh. This makes Sichuan a fertile ground for miners.
Boy I sure hope that's a typo on your part... because $0.30 is most certainly not cheap power. |

If this is the beginning of the list... jonnybravo0311 ----- btc -- 1DevLdogN52pHdjZnsgi4HzreFDB4ZHVre -- https://bitcointalk.org/index.php?action=profile;u=303978I am willing to sit out the next few rounds of this if you're looking for originals to stand down so others can jump onboard. I'll be busy the next couple of weeks (travel for work next week and vacation the following). |

kexkey confirmed right before you posted, Phil... Phil, please proceed for me like you did for jonnybravo. I confirm I received first payment. For the second, send me 2.3 BTC and keep the rest.
Thanks again. Sorry for the late reply, I was overloaded at work...
Kex.

That best share value has been sitting at just under 1B for a while now... still lots of time to hit a couple more blocks |

2.3BTC payment has been received and confirmed. Thanks, Phil!

I've (in the last few weeks) yet again reduced my mining. Now week-daily between 2pm and 8pm (when it's ~50c kWhr) I also switch off the S5 - so almost zero mining 6hrs a day (except 2GHs on an RPi that I never switch off) But ... the other day I had a think about it again and realised that between 10pm and 7am every day my elec is actually quite cheap. ... then today I actually bothered to work out what it really is for that 9hrs a day ... 9.3c/kWhr  So for the near future I'm doing ~3.7TH/s from 10pm to 7am every day and I'll dig around my old hardware and see if there's anything else worth running for that 9hrs a day. So if you notice I'm not mining on the pool, it should only be that 6hrs a week day That's a hell of a price variance... from $0.50 down to $0.093. At least you're going to get 9 hours a day, and at a pretty reasonable rate, too. |

Okay paid out 2.5 btc to all ten of us. we have 24.922xxxx in the next block I am giving ck .250 which is a match of his fee so 24.922 - .250 = 24.672 each. I know 2 people said they would tip me 0.09 each I will look back to figure out who the were. 1)jonnybravo0311------------ 1DevLdogN52pHdjZnsgi4HzreFDB4ZHVre --- I confirmed this addy paid 2.5 btc https://blockchain.info/address/1DevLdogN52pHdjZnsgi4HzreFDB4ZHVreReceived 2.5 BTC payment for block number 1. Thanks, Phil! Phil, for block number two, please only send me a payment of 2.3 BTC and keep the .1672 BTC as a tip for yourself for running this group, keeping track of the orders, organizing everything, etc. Without your efforts at ensuring orders were maintained, switched, changed as needed we wouldn't be having this discussion about how to manage the rewards for the two found blocks . EDIT: and by the way, I'm certainly willing to sit out any round. In fact, I know for a fact that I'll be out of any rounds we do the first week of June (starting May, 31) because I'll be on vacation with virtually zero access to anything online... |

another block = happy yippie yippie
btw, i found the line to show the previous blocks mined. it goes like 24*60*60.
what should i put in to show the entire week ? i used to have it but i forgot.
i'm at 168*60*60 & it shows last 4 days.
thx.
If you look at that entire bit of code, you'll see why it's only showing a limited timeframe: web_root.putChild('recent_blocks', WebInterface(lambda: [dict(
ts=s.timestamp,
hash='%064x' % s.header_hash,
number=p2pool_data.parse_bip0034(s.share_data['coinbase'])[0],
share='%064x' % s.hash,
) for s in node.tracker.get_chain(node.best_share_var.value, min(node.tracker.get_height(node.best_share_var.value), 24*60*60//node.net.SHARE_PERIOD)) if s.pow_hash <= s.header['bits'].target]))
It's pulling data from the shares it knows about and getting the block data. Since p2pool only keeps a limited set of data (as kano pointed out), it will only be able to retrieve a limited date range to calculate whether or not any blocks have been found recently. Even using blockchain.info APIs will only return a limited set of found blocks. For example, calling: https://blockchain.info/blocks/P2Pool?format=json
Will return: {
"blocks" : [
{
"height" : 357093,
"hash" : "000000000000000000040c489a058329c1aee111f8ad9651cac6a7050e58e52c",

To truly build a history of found blocks, you'll have to get details on every block found to see if it happened to be added to the chain by P2Pool. Then you use the "block notify" event from bitcoind to tell you every time a block is found, so you can go and do the same thing for the newest block. Once you do, you'll end up with something very similar to what windpath has. |

Phil, I sent you (and the whole group since I hit reply-all) a signed message from my address.
Yeah I read that, and now I'm hungry... ;P You know... I looked at this post like 5 times before what you wrote sunk in. From my address, I assume you're referring to this (which are freaking delicious): In reality, my address refers to this: As does my user name A box devil dogs a quart bottle (glass) of milk after a nickel bag of wacky- weed. I just time traveled to 1974. thanks 1974... I was 3. I was busy enjoying the milk... the devil dogs and wacky weed happened considerably later |

Anybody else notice that bitcoinwisdom's difficulty page hasn't updated for over 15 hours? How am I supposed to make a completely random guess about the change in network difficulty now??? |
