it's long run to find a block with 1,45 PH from 355 PH global hashrate or just 0.4 % from global hashrate - or i wrong  At current difficulty, 1.45PH/s expects to find a block every 1.7 days or so. (2^256 / (((2^224 - 2^208) / 49692386354) * 1450000000000000)) / 86400 = 1.70362732232241

Philip has been an asset to miners in general for a LONG time. Not only that, he will help out a newbie without making them feel like an idiot. nearly a year ago, when I was making stupid mistakes with my gridseed, he very kindly helped me out via PM for no return. Just because he was cool. He and I are nothing to each other. Not friends or enemies, just miners on the same forum. Don't besmirch the reputation of a man who has earned a good one.
Hear, hear ! I couldn't agree more. Phil has been an extremely valuable resource to both newbies and vets alike. He constantly goes out of his way to answer questions. He provides good reviews on gear and gives a nice "real-world" flavor to them (i.e. talking about the noise a miner makes in terms that are easily relatable). Oh, and manufacturers have previously chosen him to receive and review their gear (hello Spondoolies). He's earned the trust of not only the manufacturers, but also the community. |

Since the last update (20 hours ago) I'm unable to build the client on Xubuntu 64bit. When I execute the command "make -f Makefile" from within the c++ folder - I get the following error: yasm -f x64 -f elf64 -X gnu -g dwarf2 -D LINUX -o crypto/sha256_code_release/sha256_avx2_rorx2.a crypto/sha256_code_release/sha256_avx2_rorx2.asm
make: yasm: Command not found
make: *** [crypto/sha256_code_release/sha256_avx2_rorx2.a] Error 127 Everything worked fine until the last update  EDIT: The pre-compiled binary will also not run on 64bit system, giving the following error: relaynetworkclient: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by relaynetworkclient)
Do I need to download & install dependences now? EDIT2: I've reverted to the previous build until further news  sudo apt-get install yasm
Once it's installed just run make and it'll compile just fine. Hi JB, Yeah, I saw the comment on Matts thread about it. I figured that was what was needed, but just wanted to be sure, as I'd not needed it on previous builds. It's running great again now though - thanks You will be lucky if forrestv reappears in this community, he was attacked in this thread over some seriously ignorant attitudes toward his development of this software. He has not returned since, rightly so.
I'm aware of what happened previously, I've read the entire thread & am continually re-reading sections for info. There's no reason to keep harping on about what happened - posting negative, butthurt comments is neither constructive nor helpful to anyone. Please get over it & accept it like everyone else has, including forrestv who is posting here again, thankfully. Yeah... it wasn't required in his previous iterations of the relay client. I'm assuming he probably did it to try and bring parity to the *nix/win builds... but I didn't read too much into the changes he made, so I'd have to leave it up to Matt to comment on the inclusion  |

Hello!
Who uses relay netvork for p2pool?
I have an error:
user@p2pool:~/RelayNode/client$ ./relaynetworkclient public.eu.relay.mattcorallo.com 127.0.0.1 8333
illegal instruction (memory dump)
I use it... have since Matt first announced it. You might be better served by asking Matt in his thread here: https://bitcointalk.org/index.php?topic=766190.200 (which it appears you already have asked there as well). |

Hi , I'm a beginner in BTC mining  I Made in a Day 11,000 Block approximately  My question is How many Block Accepted i Need it to Create 1 BTC ? No you didn't. You had some accepted shares on whatever pool you're mining. What hardware are you using? That will help me tell you how long you can expect it to take to earn 1 BTC. solomining isn't profitable these days. you will only get negative profit because of the electricity cost and the luck you need to find a block is one in a million chance or maybe even one in a billion chance
Completely depends on how much hash you're throwing at it. If you've got 100TH/s, it's about a 1 in 24.7 chance of finding a block in a day. |

Assuming you'e on some flavor of Linux... Prod: ./bitcoind -datadir=~/.bitcoin_prod
Dev: ./bitcoind -testnet -datadir=~/.bitcoin_dev
If you ever want to run multiple production instances, you'll have to bind them each to different ports as well. You can get away with what I showed above because production runs on different ports than testnet. |

Once again... An online calculator will show that for 1TH/s right now you expect to make 0.0102 BTC a day. Expected earnings for 5 days is 0.051 BTC. 6/18, 6/19, 6/20, 6/21, 6/22 p2pool found exactly 0 blocks, meaning you earned exactly 0 BTC. Care to explain to the class how you figure 0 equals 0.051? You can clearly see the weekly results of mining on p2pool by looking at my thread: https://bitcointalk.org/index.php?topic=891298.0There isn't a single week where mining exactly matched expected earnings. It's come close, but never exactly matched expectations. Even if you mine on PPS you'll experience variance from expectations due to rejected shares. It's a fact of mining. You cannot avoid it. |

You're telling your users up front, "I'm going to utilize your computer's resources while you're here. In exchange for this, I'm providing you compensation in the form of in-game currency." If they agree to the terms, they've willingly entered into it and are basically renting you their CPU/GPU for the time they're on your site.
I don't see anything wrong with the approach. Think of things like SETI and BOINC. You donate your CPU/GPU to help find ET or a cure for cancer. With your idea, people are being compensated for your usage of their resources.

While I'm a huge supporter of p2pool, your argument here is quite flawed. For example, p2pool just went over 6 days without finding a block. Not sure how you think that p2pool is 1:1 with what an online calculator shows as expected earnings... because it's not. It's PPLNS, and it most certainly is affected by variance. You'll have swings both ways: greater than 100% of expectations and less than 100%. |

well the app its being made and legalized into android but that app its only sellable into the shop of apps and that does not gives btc
is ther a pratical way to buy app into android from BTC?
Two options: 1) Google Play starts accepting BTC as a form of payment. Good luck with that one. 2) You distribute your app outside the Play Store as EcuaMobi stated. |

Im curious about total hashrate of antpool.
Why its go up and down significantly?
If it happen in short period i think its ok but its longer than day or two.
Are they testing hardware? Somebody has big hasrate join on and off?
Only antpool can answer this.
Contrary to popular belief and the conspiracy theorists, the vast majority of the time you see swings in hash rate on a pool, or even on the entire BTC network itself, it's not because some manufacturer just turned on a boatload of new hardware. Pools and the network itself have absolutely no comprehension of actual hashing rate. All they know is how fast shares are being submitted (pool) and how fast blocks are being solved (BTC network). They use this in combination with the share difficulty (pool) or network difficulty (network) to ESTIMATE what the pool's/network's speed is. The key word there is estimate. Because of the nature of solving shares/blocks, the estimation process will show swings in hash rate. |

Is anyone else having trouble with payments?
I have not received any last 7 days.
id like to get paid too Your not begging hard enough...  Our combined oustanding balance in queue to be paid is 177.17962648 Bitcoin. There are 0 mined blocks waiting to mature, totalling 0 Bitcoin Hey... they're less than 200 BTC behind in payouts... that's got to be a record  |

I love how the highlighted features are the DVI/HDMI ports to connect your monitor and the USB ports to connect your keyboard and mouse. Poor dumb bastards that actually place an order for this thing... another day another scam I guess.

Anyway OP, if you're still interested in mining with your computer then you could try mining altcoins and converting these to bitcoins using an altcoin exchange like Cryptsy. There are many altcoins out there which can still be mined using CPUs or GPUs. The only ones which have ASICs built for them are SHA-256 based coins like Bitcoin and Peercoin, and scrypt-based coins like Litecoin and Dogecoin.
Agree. In most country, the electricity cost will never make you profit mining Bitcoin. However, mining altcoin might give you a little profit. Well, most altcoin difficulty is lower compared to Bitcoin. Also, instead of mining by yourself, joining a pool might speed it up. If you intend to mine Altcoin and join a pool.. Choose a pool which will automatically mine profitable altcoin and exchange it into Bitcoin for you. It's not because of electricity costs that mining Bitcoin using general purpose hardware is a bad idea. It's because of ASICs. A single ASIC is equivalent to an entire warehouse full of computers. If a coin has ASICs developed for it, then these ASICs are competing with your single computer for the same block reward and because of this, your single computer always inevitably loses. Even tiny SHA-256 coins like Betacoin and Terracoin can't really be mined using CPUs or GPUs anymore in any reasonable sense because the existence of a single ASIC mining on the network is enough to outclass hundreds of CPU and GPU miners. Actually it is indeed about the cost of electricity. The presence of ASICs drives up the difficulty, but at the end of the day it comes down to the cost of producing X units of a coin. An ASIC, as you correctly point out is considerably more efficient at hashing than a CPU, GPU or FPGA. The most efficient ASICs out right now are hashing at between 0.4 and 0.5 Watts per GH/s. Even more efficient gear is on the horizon (and likely already being tested/mined). Sure, back 3 and 4 years ago mining Bitcoin with a CPU was indeed a viable option. Then people figured out that using a GPU was more efficient - you got more bang for your electricity dollar. Then along came FPGA, which were even better. Finally came the ASICs, which are even better still. Why would you use your 450W Radeon R9 295X to mine BTC, getting speeds measured in MH/s, when you could spend that same 450W on two ancient overclocked S1s getting 400GH/s (or newer gear for greater hash speed and less power draw)? It's all about the cost of that precious fuel (i.e. electricity) powering your devices. Right now, with the exchange rate of BTC, even relatively new gear struggles to earn you anything above and beyond the cost of operating it. For example, assuming you've got power costs of $0.10 per kWh, an S5 would only expect to bring in $1.47 a day. An S3 would only expect to make $0.29 a day. As you can see, it isn't even worth thinking about firing up that CPU/GPU to mine BTC because all you're going to do is burn electricity for no reward. |

Just another weekly update... p2pool's good luck streak came crashing to a halt these past 7 days. Oh, and retrocalc.net needs some loving... the calculations are nowhere near correct (noticed it last week, and it's still going on). The standard p2pool payout beat NastyPoP, but neither of them met the expected earnings:
NastyPoP - 0.01964088BTC
NastyP2P - 0.02788807BTC
Expected - 0.030107BTC
Luck - 65.12%
OP updated

I would probably wait at this point to see what Bitmain and Sfards releases in the next couple of months.
Yeah, the S5 is getting old, i'm waiting for the new hardware too. I see some guys create a chip who can do bitcoin and litecoin mining at the same time. I think that is the future. Is better wait a lil bit and buy when the new hardware came to the market. It's not really a new idea... in fact SFARDS, the company that is making the BTC/LTC combo is composed at least in part by gridseed as far as I know. Gridseed, if you recall, made those dual chip orbs last year. As far as it being the future, I'm not entirely sure about that, but it is definitely a pretty interesting project. |

Hi,
What happens to the Namecoin balance if it's less than the minimum...will we be able to withdraw them manually at some point?
The 0.00xxxxx NMC balances will be funding my mansion...made of cardboard....and roughly the size of a car. These amounts are worth less than half of a penny. Please accept my current balances of 0.00828663 BTC and 0.00021412 NMC at BTC Guild as a donation towards your new mansion. Maybe you'll be able to upgrade to corrugated cardboard now |

I don't think that this discussion went in the right way. In general I believe that people don't know if empty blocks are good or bad (neither do I). Instead of discussing the total amount of empty blocks someone should try to explain this in a single post that we can relate to in the future. I'm not really interested in the exact number, however looking at the picture we can clearly see that AntPool has the highest percentage. Empty blocks aren't useless as they confirm previous transactions and secure them further against attacks. Though, they are much less useful than normal blocks. I am assuming the 23% number is skewed by 2009 and 2010 blocks which were mosly empty due to not having actual transactions rather than being empty on purpose by miners. 25 out of 1000 last which makes 2.5% seem much more right to work on.
I think miners shouldn't mine empty blocks because they would lose tx fee and make people await more time for their tx to be included in the chain. Why do some pools do that? Is there an advantage?
Can someone confirm this or elaborate the usefulness of empty blocks? It's a debate that has supporters on both sides of the argument. I am pretty firmly entrenched on the side that believes empty blocks are a waste if they are added simply to add a block to the chain. Now, if there really are no transactions to be included - which was the case quite a bit at the beginning of the block chain - then, by all means if you find a valid solution add the block, because as chalkboard17 points out, even an empty block provides value in securing the blockchain. Some pools are coded in such a way as to provide empty blocks to their miners until the pool can properly provide transactions. Whether this is a limitation of the language in which the pool is written, the inability of the pool's coder(s) to properly include transaction, or some other factor, it's wrong. Kano has provided very clear evidence that the claims of "we do it this way because it's faster" that the empty block guys stand on is indeed patently false. Since there are almost always plenty of transactions to be included in a block, then I believe it is up to the pool to properly include those transactions in any work it provides to miners. Creating a block just for the sake of creating a block because your pool can't push work out quickly enough is an excuse for poorly coded software and not a valid reason. Why should all those transactions have to wait another ~10 minutes to be included on the blockchain? |

I'm currently pointing to - stratum+tcp://stratum.antpool.com:3333
This doesn't mean I'm solo mining right? This is pooled mining and I have to pay 1% fee or something...
Should I also include stratum+tcp://stratum.antpool.com:25 + :443 ?
What if I pointed to solo.antpool.com instead? Would that be solo mining?
LOL... you ask us for recommendations, then you come back and tell us you're pointing to antpool. No, you are not solo mining pointing your S5 to stratum.antpool.com:3333. Ports 25 and 443 are only there in case you've got some kind of network problems preventing you from hitting their standard stratum port. solo.antpool.com is not solo mining either. It's the same pool as stratum.antpool.com. What they mean by "solo" is absurd. Most every pool works like they describe their "solo" pool. There's nothing magical about it. Now, in my opinion I don't particularly like antpool. I mentioned some choices in my first post... here are some good reputable pools that I recommend: p2pool - because I mine here and like it kano.is - run by the guys who wrote your mining software bitminter - DrHaribo is always on here and responds on the pool thread regularly slush - pretty much the first pool ever MRR - great way to remotely manage your gear (I have used it for over 7 months). nicehash/westhash - rental site that is PPS for 3%. A lot of times you can make more than expectations due to higher demands for rentals. |
