A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.
Bounty: 0.1 BTC for a Bitcoin mining client capable of the block-solution withholding attack.
Goal Bitcoin is threatened by the existence of mining pools large enough to enable a 51% attack. A block-solution withholding attack consists of miners on a pool sending work to the pool operator in exchange for Bitcoin, but upon finding a valid block solution choosing not to send the solution to the pool operator. A successful block-solution withholding attack allows activist Bitcoin miners to cause financial losses to a pool operator, as explained in a paper by Rosenfeld. This in turn would lead to lower payout to other Bitcoin miners using a pool facing a block-solution withholding attack. This leads those miners to leave, which increases the proportion of miners using the attack. In the long run, the result would be that joining larger mining pools no longer provides a financial incentive to miners, as a result of the presence of activist miners. Miners thus receive a financial incentive to stick to small pools that are not perceived as threatening to the integrity of the network. Problem Currently no reliable and easy Bitcoin mining client exists that can be used for a block solution withholding attack, even though the changes required to a mining client are very minor. Thus for now, the block-solution withholding attack has remained a theoretical construct. Solution I offer 0.1 BTC as a bounty to anyone willing to program a reliable user-friendly mining client that allows owners of mining hardware to carry out a block-solution withholding attack against mining pools. Hopefully others are willing jump in and raise the bounty. After we agree on specifications that the mining client should have, we send the bounty to a multisig address, controlled by trusted members of the community. When those members agree that a satisfying mining client has been produced, they send the bounty to the developer's address.
I am a high school student doing a bitcoin mining client for a business project.
Hi guys and girls, I am currently in a business week in which we launch a product or service. When I started mining about a year ago, it took me a lot of time and research to figure everything out. I realize this is definitely something that could scare people away from bitcoin. So I have decided to create a mining client that would come preconfigured for a pool (that I would also run) so that people who aren't as tech-savvy can still mine for bitcoins in an attempt to simplify the process. I realize that these people would be mining on the PC's, not ASIC mining devices and are not going to really get anything done, but if someone was that serious about mining then this isn't necessarily for them. I have developed a website to basically see how many people would be interested in this service (any feedback on the site is welcome, I am not the best), and if this is something I should pursue. Here is the website I have made: http://easy-miner.launchrock.com/ Thanks for you time and feedback! Also, I haven't actually made anything yet, this is just putting my toes into the water to see if it might be worth it. If you guys think this would be cool I would love for you to sign up on my website and send me any feedback or ideas you want to see. Thank you so much!
Bitcoin historians your help is requested: Pretend you downloaded one of the first bitcoin mining clients ever. What would it have been called on your computer (in windows and Linux versions) and in what file name would it have stored your bitcoins?
Bitcoin historians your help is requested: Pretend you downloaded one of the first bitcoin mining clients ever.

I am doing a forensic search of some old hard drives just for giggles. What files names should i look for?

NM-MG1 rank area has become unplayable because of smurfs for me and my friends?
Me an my friend mostly 5 queue and recently smurfs have made the game unplayable. Out of the past 12 matches we had 11 were fully occupied by smurfs usually 3-4 queing. Every time we say it will be different. We play until it becomes apparent that we will lose and then we take turns on who will be the martyr and take the cool down so we can just surrender because we usually don't have much time where we can get 5 people online to play. Why do people do this? Usually at half time they are like "you guys suk!!!1!!1!" and one of use will say "why is this fun for you?" No one ever answers, how do they gain enjoyment? How can we combat this w/o aimbot. We go into aim servers then deathmatch then retake then when we go into comp and get 16-3'ed. No matter how many dank smokes, popflashes, and strats we know we cant help just getting out aimed. I realize that we in the nm-mg1 area are pretty bad and dont get taken seriously around here but there I don't know how to get better at this rate. I was thinking maybe do like cevo or faceit(popflash?)(would rather do esea but the starting rank for esea is way to high and i have no intention of installing a bitcoin mining client on my computer). Which one of these two services have the lowest entry rank? Haha down votes should of know better
I know my way around the world of bitcoins but I'm not an expert, so I came here looking for anything: advice, doubts, constructive criticism, and hopefully some help. I want to start a charity unlike any other out there yet. Basically I plan on creating a bitcoin mining client optimized to allow many users across the world to mine on their inneficient computers at a low power consumption and automatically dump the earnings to a central location. The earnings would be small, but the .0001 bitcoins would add up. I could try to do this all myself, but I believe a project like this will only work if it operates in a similar capacity and mentality to something like Wikipedia: a free resource open to everyone with the potential to make life just a little bit brighter. This is why I came to reddit. I want to learn more about bitcoin, but I also want to invite everyone here that is interested to collaborate with me on this project. Ideally I'd like to quit my job and work with charities full time, but the way I see this starting out is just voting on charities to donate to every month and giving the full amount of money gathered away. Longer term, if this idea actually takes off, I'd like to add more functionality to the mining client, allowing users to create a 'volunteer network' and establish a online community based on helping others and meeting the needs of the user's local community. When linked with facebook, twitter, and other social media, I believe this idea of helping each other out could spread. People love the idea of '1 like = 1 meal for an orphan' but so far it's been empty sentimentality. I'd like to give that idea a fighting chance. If you'd like to join the project or offer help or advice or criticism or really anything, feel free to post here or PM me. Even if you're not interested, an upboat for visibility would mean a lot to me. EDIT: I removed an unnecessary link, just pm if you come across this and wanna help out.
Bitcoin is a cryptographic money - an arrangement of carefully made and exchanged tokens to which esteem is relegated. PCs need to take care of cryptographic issues keeping in mind the end goal to add pieces to the blockchain - a record that records each exchange that has ever happened with Bitcoin. Consequently, those PCs get bitcoins in a procedure known as bitcoin "mining". Clients have a "bitcoin address", to which bitcoins might be sent or from which they might be utilized. Locations are put away online in wallets that capacity like financial balances.Albeit the vast majority allude to Bitcoin as a cash, it is important that for administrative reasons numerous nations - including the Assembled States - have chosen to characterize it as a ware.
Windows 10 wakes up from sleep automatically for no known reason.
So, I've been using 10 since the pre-release insider previews with minimal issues (aside from usual blue screens whenever I am doing something important) until recently. During the past few months, my computer has, perhaps once a week tops, turns itself on when in sleep mode. However in the last two weeks, the issue has gotten MUCH worse. I have not installed any updates during this period, nor has Windows pissed me off by restarting to install any automatically without my permission. In the past, I have disabled wake over LAN, I have removed the ability for my mouse and keyboard to wake the computer, both in the OS and in my BIOS, going as far as completely unplugging them. None of this has changed anything. Now it wakes up EVERY SINGLE NIGHT. Without fail, the computer will wake itself up at 6:55, 7:55, 8:55, and 9:55 PM, give or take 5 minutes. I can pull up an elevated command prompt to execute powercfg -lastwake and it says "unknown source", or "0 wake sources". I open up event viewer, go under the system event logs and filter for the "Power Troubleshooter" category to see all of the waking events. I see my USB controller whenever I interact with the mouse or keyboard, but every day while I'm doing homework on my laptop, the computer just wakes up, leaving an "Unknown Wake Source" event each time. I have checked so many times to see if I have any wake timers enabled, which I don't. My bitcoin mining client (back when it was profitable) and my Folding at Home client were able to interfere with the computer going to sleep, but I have since completely uninstalled them and all of their dependencies to little effect. If anyone has any suggestions, please put them forth. I have been digging for a few weeks now to try and find other people with similar problems, but they have all been related to wake timers or peripherals triggering the wakeup. Even unplugging all of my peripherals (ALL of them. Just a power cord and monitor hookups plugged in), has yielded no results. Just to clarify the specs of my system, here we go. (go easy on me, I'm rebuilding before I move into college.) CPU: Core i5-3570k OC'd at 4.6 GHz GPU: (EVGA) Nvidia GTX 760 (FTW ed.) - I haven't updated the drivers in a month, so the problem isn't related. OS: Windows 10 Home (insider) Version 1607, build 14393.953, 64 bit Other: 16gb of RAM, 3 monitors in a triple-wide setup. EDIT: Yes, I've already scanned with Windows Defender and Malwarebytes in Chameleon mode and I've come up with nothing.
I did it as a tribute to our missing Satoshi: we are missing Satoshi, and now the blockchain is missing 1 Satoshi too, for all time.
EDIT: Users have pointed out in the comments that this isn't actually the only time coins have been destroyed, there are actually several different ways coins have been destroyed in the past. sumBTC also points out that the satoshi wasn't destroyed-- it was never created in the first place. Another interesting way to destroy coins is by creating a duplicate transaction. This is again done with a modified client. For example see block 91722 and block 91880. They both contain txid e3bf3d07. The newer transaction essentially overwrites the old transaction, destroying the previous one and the associated coins. This issue was briefly discussed on Github #612 and determined to not be a big deal. In 2012 they realized that duplicated transactions could be used as part of an attack on the network so this was fixed and is no longer possible. Provably burning coins was actually added as a feature in 2014 via OP_RETURN. Transactions marked with this opcode MAY be pruned from a client's unspent transaction database. Whether or not these coins still exist is a matter of opinion. Finally, at least 1,000 blocks forfeited transactions fees due to a software bug. Forfeited transaction fees are lost forever and are unaccounted for in any wallet.
Between block 162705 and block 169899, 193 blocks claimed less than allowed due to a bug, resulting in a total loss of 9.66184623 BTC.
Between block 180324 and block 249185, another 836 blocks claimed less than allowed, resulting in a total loss of 0.52584193 BTC.
