Ethereum CUDA miner - Crypto Mining Blog

Mining noob, I have some questions

Hi everyone, a quick intro here: I come from a professional horticulture background. I've been learning about computers, networking, network security and Linux sys. admin for the last two years. I built a bunch of gaming computers for my kids and I with a bonus check I got in fall of 2017, right before the 2017 "bitcoin bubble". By luck I grabbed all my parts before the price of GPU's skyrocketed. All I've been doing though is learning about Linux and game development, learning digital art like 3D modeling, and streaming video games.
I'm now learning to mine ZEC with tpruvot/ccminer 2.3.1 in Ubuntu 20.04 with Nvidia proprietary driver vers. 440 & CUDA toolkit 10.1. I'm just learning how to do this and understand I'm not making a profit. I'ts more a learning experience and a hobby sort of thing for now. I dont really care if the system breaks, I have another computer with AMD RX560 that I work and game on Linux with. I cant mine with the pollaris GPU because I cant install OpenCL. There is no support for 20.04 from catalyst driver as of now.
TL;DR I'm a noob and wondering why my hashrate is what it is. I am only using 1 GPU as of now (Nvidia 1050Ti 4GB) and mining on a pool. I get an average of 140 Sol/s. Is this essentially the same as H/s and is that a normal number for my card? Should I add a 2nd GPU I have if it's only a 1050 2GB? Also, I am using nvtop & htop packages to monitor PC stats, it shows it's using 99% of GPU and 100% of a single core of my CPU (intel i5 6402P @ 3.2GHz) fans and temps are good.
But it shows I'm only using .6GB / 4GB while mining, is that right? Shouldn't it be using more memory? Would it be overkill to mine with CPU miner at the same time as the 2 cards?
Sorry about the essay, and thanks for your time

Number crunching/Deep learning machine needed

Hi,
I have tried to build my own, but it appears like I've gotten rusty in this. It has also reached prices beyond my expectations. But I want to keep it for about 7-10 years.
What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
I don't plan to use this for gaming or bitcoin mining. I will process a lot of text from external sources, compute numbers, and train some deep learning models.
What is your maximum budget before rebates/shipping/taxes?
4000 USD / 36000 NOK.
When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.
ASAP
What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc)
Things I would want:
CPU: AMD Ryzen 9 3950X (or something fast that has 16+ cores; I will run highly parallel jobs) GPU: GeForce RTX 2080 Ti (large memory is preferred) Memory: 32GB (or more) Motherboard: Preferably an X570 with PCIe 4.0 NVMe support. WiFi would be nice, because there is no network cabling around that area. USB-C heads would be nice, but not required. Case: USB-C is required. I prefer white, silvegrey, but black would be fine as well. No disc drive needed. Storage: NVMe (1 TB should be enough for me, I suppose). I already have an SSD inside my old machine. PSU: 850W or higher would be good. I have plans to install another card in that. Fans: I have no idea how many I need, nor where to mount them. Something less noisy would be nice. If water cooling is less-noisy and comparable in terms of pricing, I can go for water cooling.
Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?
Norway
If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
SSD (Samsung evo 850), keyboard, mouse, monitor. Brands of those don't matter.
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
Most likely, no. However, it appears like both the CPU and the GPU can be overclocked to a certain extent.
Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)
CUDA and OpenCL support would be required. I already have an SSD. But an NVMe drive is needed.
Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?
I don't like LED lighting. I prefer white, silver or grey cases. Size doesn't matter as long as I can place 2 full size PCIe cards in that. I don't like window, but don't mind if a cheap model has that.
Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?
No. It will run Linux.
Extra info or particulars:
Nothing apart from those.
I would be very happy, if you could help me build something along these lines.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Looking back 18 months.

I was going through old emails today and came across this one I sent out to family on January 4, 2018. It was a reflection on the 2017 crypto bull market and where I saw it heading, as well as some general advice on crypto, investment, and being safe about how you handle yourself in cryptoland.
I feel that we are on the cusp of a new bull market right now, so I thought that I would put this out for at least a few people to see *before* the next bull run, not after. While the details have changed, I don't see a thing in this email that I fundamentally wouldn't say again, although I'd also probably insist that people get a Yubikey and use that for all 2FA where it is supported.
Happy reading, and sorry for some of the formatting weirdness -- I cleaned it up pretty well from the original email formatting, but I love lists and indents and Reddit has limitations... :-/
Also, don't laught at my token picks from January 2018! It was a long time ago and (luckliy) I took my own advice about moving a bunch into USD shortly after I sent this. I didn't hit the top, and I came back in too early in the summer of 2018, but I got lucky in many respects.
----------------------------------------------------------------------- Jan-4, 2018
Hey all!
I woke up this morning to ETH at a solid $1000 and decided to put some thoughts together on what I think crypto has done and what I think it will do. *******, if you could share this to your kids I’d appreciate it -- I don’t have e-mail addresses, and it’s a bit unwieldy for FB Messenger… Hopefully they’ll at least find it thought-provoking. If not, they can use it as further evidence that I’m a nutjob. 😉
Some history before I head into the future.
I first mined some BTC in 2011 or 2012 (Can’t remember exactly, but it was around the Christmas holidays when I started because I had time off from work to get it set up and running.) I kept it up through the start of summer in 2012, but stopped because it made my PC run hot and as it was no longer winter, ********** didn’t appreciate the sound of the fans blowing that hot air into the room any more. I’ve always said that the first BTC I mined was at $1, but looking back at it now, that’s not true – It was around $2. Here’s a link to BTC price history.
In the summer of 2013 I got a new PC and moved my programs and files over before scrapping the old one. I hadn’t touched my BTC mining folder for a year then, and I didn’t even think about salvaging those wallet files. They are now gone forever, including the 9-10BTC that were in them. While I can intellectually justify the loss, it was sloppy and underlines a key thing about cryptocurrency that I believe will limit its widespread adoption by the general public until it is addressed and solved: In cryptoland, you are your own bank, and if you lose your password or account number, there is no person or organization that can help you reset it so that you can get access back. Your money is gone forever.
On April 12, 2014 I bought my first BTC through Coinbase. BTC had spiked to $1000 and been in the news, at least in Japan. This made me remember my old wallet and freak out for a couple of months trying to find it and reclaim the coins. I then FOMO’d (Fear Of Missing Out”) and bought $100 worth of BTC. I was actually very lucky in my timing and bought at around $430. Even so, except for a brief 50% swing up almost immediately afterwards that made me check prices 5 times a day, BTC fell below my purchase price by the end of September and I didn’t get back to even until the end of 2015.
In May 2015 I bought my first ETH at around $1. I sent some guy on bitcointalk ~$100 worth of BTC and he sent me 100 ETH – all on trust because the amounts were small and this was a small group of people. BTC was down in the $250 range at that point, so I had lost 30-40% of my initial investment. This was of the $100 invested, so not that much in real terms, but huge in percentages. It also meant that I had to buy another $100 of BTC on Coinbase to send to this guy. A few months after I purchased my ETH, BTC had doubled and ETH had gone down to $0.50, halving the value of my ETH holdings. I was even on the first BTC purchase finally, but was now down 50% on the ETH I had bought.
The good news was that this made me start to look at things more seriously. Where I had skimmed white papers and gotten a superficial understanding of the technology before FOMO’ing, I started to act as an investor, not a speculator. Let me define how I see those two different types of activity:
So what has been my experience as an investor? After sitting out the rest of 2015 because I needed to understand the market better, I bought into ETH quite heavily, with my initial big purchases being in March-April of 2016. Those purchases were in the $11-$14 range. ETH, of course, dropped immediately to under $10, then came back and bounced around my purchase range for a while until December of 2016, when I purchased a lot more at around $8.
I also purchased my first ICO in August of 2016, HEAT. I bought 25ETH worth. Those tokens are now worth about half of their ICO price, so about 12.5ETH or $12500 instead of the $25000 they would be worth if I had just kept ETH. There are some other things with HEAT that mean I’ve done quite a bit better than those numbers would suggest, but the fact is that the single best thing I could have done is to hold ETH and not spend the effort/time/cost of working with HEAT. That holds true for about every top-25 token on the market when compared to ETH. It certainly holds true for the many, many tokens I tried to trade in Q1-Q2 of 2017. In almost every single case I would have done better and slept better had I just held ETH instead of trying to be smarter than Mr. Market.
But, I made money on all of them except one because the crypto market went up more in USD terms than any individual coin went down in ETH or BTC terms. This underlines something that I read somewhere and that I take to heart: A rising market makes everyone seem like a genius. A monkey throwing darts at a list of the top 100 cryptocurrencies last year would have doubled his money. Here’s a chart from September that shows 2017 year-to-date returns for the top 10 cryptocurrencies, and all of them went up a *lot* more between then and December. A monkey throwing darts at this list there would have quintupled his money.
When evaluating performance, then, you have to beat the monkey, and preferably you should try to beat a Wall Street monkey. I couldn’t, so I stopped trying around July 2017. My benchmark was the BLX, a DAA (Digital Asset Array – think fund like a Fidelity fund) created by ICONOMI. I wasn’t even close to beating the BLX returns, so I did several things.
  1. I went from holding about 25 different tokens to holding 10 now. More on that in a bit.
  2. I used those funds to buy ETH and BLX. ETH has done crazy-good since then and BLX has beaten BTC handily, although it hasn’t done as well as ETH.
  3. I used some of those funds to set up an arbitrage operation.
The arbitrage operation is why I kept the 11 tokens that I have now. All but a couple are used in an ETH/token pair for arbitrage, and each one of them except for one special case is part of BLX. Why did I do that? I did that because ICONOMI did a better job of picking long-term holds than I did, and in arbitrage the only speculative thing you must do is pick the pairs to trade. My pairs are (No particular order):
I also hold PLU, PLBT, and ART. These two are multi-year holds for me. I have not purchased BTC once since my initial $200, except for a few cases where BTC was the only way to go to/from an altcoin that didn’t trade against ETH yet. Right now I hold about the same 0.3BTC that I held after my first $100 purchase, so I don’t really count it.
Looking forward to this year, I am positioning myself as follows:
Looking at my notes, I have two other things that I wanted to work into this email that I didn’t get to, so here they are:
  1. Just like with free apps and other software, if you are getting something of value and you didn’t pay anything for it, you need to ask why this is. With apps, the phrase is “If you didn’t pay for the product, you are the product”, and this works for things such as pump groups, tips, and even technical analysis. Here’s how I see it.
    1. People don’t give tips on stocks or crypto that they don’t already own that stock or token. Why would they, since if they convince anyone to buy it, the price only goes up as a result, making it more expensive for them to buy in? Sure, you will have friends and family that may do this, but people in a crypto club, your local cryptocurrency meetup, or online are generally not your friends. They are there to make money, and if they can get you to help them make money, they will do it. Pump groups are the worst of these, and no matter how enticing it may look, stay as far away as possible from these scams. I even go so far as to report them when I see them advertise on FB or Twitter, because they are violating the terms of use.
    2. Technical analysis (TA) is something that has been argued about for longer than I’ve been alive, but I think that it falls into the same boat. In short, TA argues that there are patterns in trading that can be read and acted upon to signal when one must buy or sell. It has been used forever in the stock and foreign exchange markets, and people use it in crypto as well. Let’s break down these assumptions a bit.
i. First, if crypto were like the stock or forex markets we’d all be happy with 5-7% gains per year rather than easily seeing that in a day. For TA to work the same way in crypto as it does in stocks and foreign exchange, the signals would have to be *much* stronger and faster-reacting than they work in the traditional market, but people use them in exactly the same way.
ii. Another area where crypto is very different than the stock and forex markets centers around market efficiency theory. This theory says that markets are efficient and that the price reflects all the available information at any given time. This is why gold in New York is similar in price to gold in London or Shanghai, and why arbitrage margins are easily <0.1% in those markets compared to cryptoland where I can easily get 10x that. Crypto simply has too much speculation and not enough professional traders in it yet to operate as an efficient market. That fundamentally changes the way that the market behaves and should make any TA patterns from traditional markets irrelevant in crypto.
iii. There are services, both free and paid that claim to put out signals based on TA for when one should buy and sell. If you think for even a second that they are not front-running (Placing orders ahead of yours to profit.) you and the other people using the service, you’re naïve.
iv. Likewise, if you don’t think that there are people that have but together computerized systems to get ahead of people doing manual TA, you’re naïve. The guys that I have programming my arbitrage bots have offered to build me a TA bot and set up a service to sell signals once our position is taken. I said no, but I am sure that they will do it themselves or sell that to someone else. Basically they look at TA as a tip machine where when a certain pattern is seen, people act on that “tip”. They use software to see that “tip” faster and take a position on it so that when slower participants come in they either have to sell lower or buy higher than the TA bot did. Remember, if you are getting a tip for free, you’re the product. In TA I see a system when people are all acting on free preset “tips” and getting played by the more sophisticated market participants. Again, you have to beat that Wall Street monkey.
  1. If you still don’t agree that TA is bogus, think about it this way: If TA was real, Wall Street would have figured it out decades ago and we would have TA funds that would be beating the market. We don’t.
  2. If you still don’t agree that TA is bogus and that its real and well, proven, then you must think that all smart traders use them. Now follow that logic forward and think about what would happen if every smart trader pushing big money followed TA. The signals would only last for a split second and would then be overwhelmed by people acting on them, making them impossible to leverage. This is essentially what the efficient market theory postulates for all information, including TA.
OK, the one last item. Read this weekly newsletter – You can sign up at the bottom. It is free, so they’re selling something, right? 😉 From what I can tell, though, Evan is a straight-up guy who posts links and almost zero editorial comments.
Happy 2018.

Mining ERC-918 Tokens (0xBitcoin)

GENERAL INFORMATION

0xBitcoin (0xBTC) is the first mineable ERC20 token on Ethereum. It uses mining for distribution, unlike all previous ERC20 tokens which were assigned to the contract deployer upon creation. 0xBTC is the first implementation of the EIP918 mineable token standard (https://eips.ethereum.org/EIPS/eip-918), which opened up the possibility of a whole new class of mineable assets on Ethereum. Without any ICO, airdrop, pre-mine, or founder’s reward, 0xBitcoin is arguably the most decentralized asset in the Ethereum ecosystem, including even Ether (ETH), which had a large ICO.
The goal of 0xBitcoin is to be looked at as a currency and store of value asset on Ethereum. Its 21 million token hard cap and predictable issuance give it scarcity and transparency in terms of monetary policy, both things that Ether lacks. 0xBitcoin has certain advantages over PoW based currencies, such as compatibility with smart contracts and decentralized exchanges. In addition, 0xBTC cannot be 51% attacked (without attacking Ethereum), is immune from the “death spiral”, and will receive the benefits of scaling and other improvements to the Ethereum network.

GETTING 0xBITCOIN TOKENS

0xBitcoin can be mined using typical PC hardware, traded on exchanges (either decentralized or centralized) or purchased from specific sites/contracts.

-Mined using PC hardware

-Traded on exchanges such as


MINING IN A NUTSHELL

0xBitcoin is a Smart Contract on the Ethereum network, and the concept of Token Mining is patterned after Bitcoin's distribution. Rather than solving 'blocks', work is issued by the contract, which also maintains a Difficulty which goes up or down depending on how often a Reward is issued. Miners can put their hardware to work to claim these rewards, in concert with specialized software, working either by themselves or together as a Pool. The total lifetime supply of 0xBitcoin is 21,000,000 tokens and rewards will repeatedly halve over time.
The 0xBitcoin contract was deployed by Infernal_Toast at Ethereum address: 0xb6ed7644c69416d67b522e20bc294a9a9b405b31
0xBitcoin's smart contract, running on the Ethereum network, maintains a changing "Challenge" (that is generated from the previous Ethereum block hash) and an adjusting Difficulty Target. Like traditional mining, the miners use the SoliditySHA3 algorithm to solve for a Nonce value that, when hashed alongside the current Challenge and their Minting Ethereum Address, is less-than-or-equal-to the current Difficulty Target. Once a miner finds a solution that satisfies the requirements, they can submit it into the contract (calling the Mint() function). This is most often done through a mining pool. The Ethereum address that submits a valid solution first is sent the 50 0xBTC Reward.
(In the case of Pools, valid solutions that do not satisfy the full difficulty specified by the 0xBitcoin contract, but that DO satisfy the Pool's specified Minimum Share Difficulty, get a 'share'. When one of the Miners on that Pool finds a "Full" solution, the number of shares each miner's address has submitted is used to calculate how much of the 50 0xBTC reward they will get. After a Reward is issued, the Challenge changes.
A Retarget happens every 1024 rewards. In short, the Contract tries to target an Average Reward Time of about 60 times the Ethereum block time. So (at the time of this writing):
~13.9 seconds \* 60 = 13.9 minutes
If the average Reward Time is longer than that, the difficulty will decrease. If it's shorter, it will increase. How much longer or shorter it was affects the magnitude with which the difficulty will rise/drop, to a maximum of 50%. * Click Here to visit the stats page~ (https://0x1d00ffff.github.io/0xBTC-Stats) to see recent stats and block times, feel free to ask questions about it if you need help understanding it.

MINING HARDWARE

Presently, 0xBitcoin and "Alt Tokens" can be mined on GPUs, CPUs, IGPs (on-CPU graphics) and certain FPGAs. The most recommended hardware is nVidia graphics cards for their efficiency, ubiquity and relatively low cost. As general rules, the more cores and the higher core frequency (clock) you can get, the more Tokens you will earn!
Mining on nVidia cards:
Mining on AMD cards:
Mining on IGPs (e.g. AMD Radeon and Intel HD Graphics):

Looking to upgrade/redo current PC build

I built my PC a couple years ago when bitcoin mining was popular and paid more than I should have for the build I got. Now I’m looking to either start fresh and reuse parts that are viable in a new build or to see if it’s just possible to upgrade some things to make my PC run better. Right now it’s not great for modern AAA games and the like.
What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
What is your maximum budget before rebates/shipping/taxes?
  • I would prefer to keep it around 800 but can go up to 1000 if absolutely needed
When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.
  • Around Black Friday/Cyber Monday most likely
What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc)
  • I don’t necessarily need a monitokeyboard/mouse as I already have those but they are barebones so if I can include them in my budget I’d be willing to upgrade
Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?
  • Michigan, USA. Yes I have a micro center near me
If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
  • The parts listed below are all the ones I have in my build currently. I’m not sure if it would be worth it upgrading separate parts or building a whole new one and reusing what I can, so I included a full part list.
  • OS - Windows 10
  • Motherboard - MSI B250M Bazooka (MS-7A70)
  • CPU/Processor - Intel Core i5 7500 @ 3.40ghz
  • GPU/Graphics Card - Zotac GeForce GTX 1050-Ti 4gb
  • Ram - Crucial Ballistix Sport DDR4 2400 C16 2x4gb
  • Hard Drive - WD Blue 1 TB
  • Case - DeepCool Tesseract Mid-Tower Case (Blue/Black)
  • Keyboard - Razer Cynosa Chroma
  • Mouse - Steel series Rival 300 Mouse
  • Mouse Pad - Rager Goliathus Chroma
  • Speakers/Subwoofer - Logitech Z313 2-1 channel 3 piece speaker system with subwoofer
  • Monitor: Lenovo LI2264D wide 21.5 inch
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
  • Not 100% as I have no experience overclocking
Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)
  • I would like an SSD but that’s all I can think of
Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?
  • I would prefer a mid tower size just because I don’t have all the space in the world for a huge tower. See through window and rgb/blue theme if possible
Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?
  • No
Extra info or particulars:
  • I think I covered it all, thank you to anyone who helps me out!

GPU acceleration of full nodes like Bitcoin Core? (NOT mining)

Hi all – Do you think Bitcoin Core and other full node implementations might benefit from GPU acceleration?
Note that I don't mean mining – I mean pure node operations, validation, etc.
By GPU acceleration I mostly mean the use of APIs like OpenCL, DirectX / DirectMath, CUDA, and Apple's Metal. Some of the work currently done by the CPU would be offloaded to the GPU, probably using one of those APIs.
I've read different accounts of how much a full node taxes a CPU, from barely at all to major CPU usage. I guess GPU acceleration would make the most sense if CPU usage was sometimes a problem, and if some part of a full node's computational work could actually be performed by a GPU. And there's where I just don't know enough to know the answer, hence my question today.
Because it's not mining, I think even integrated GPUs like Intel's or the ones that come with Raspberry Pi Arm SOCs could be helpful, if GPUs would be helpful at all. Intel has some great open source drivers for things like OpenCL, and it might be fun to mess around with them.
Thanks for your thoughts.

Release Thread: https://www.reddit.com/0xbitcoin/comments/c1590e/cosmic_v413t_update_nvidiacuda_win64_guibased/
Thanks!
Hello, 0xBitcoin Community! I'm happy to share my work with you today! This is a brand new CUDA miner for Pool-Mining 0xBitcoin and similar ERC-918 tokens like 0xBitcoinCash/0xKIWI. I've rewritten COSMiC from the ground up, using the best parts of v3.4 (the fastest/most stable release prior to this one.) Presenting, COSMiC V4! As I add more features to this miner, my goal is to make it as simple and pleasant to use as possible for newcomers to 0xBitcoin and mining in general.
SCREENSHOTS:
DOWNLOAD: (Out-Of-Date: See v4.0.1 link above)
FEATURES:
WHAT'S COMING SOON:
COMPATIBILITY:
Should work on nVidia(CUDA) cards Kepler(6xx-series) and up. Tested on Maxwell Gen2(9xx) and Pascal (GTX10x0). Developed on Windows 10. Should work on 8.1 and up (probably works on 7.) This is a 64-bit application and expects a 64-bit version of Windows.
Non-English Windows Users: **If the program crashes or doesn't launch when you double-click Cosmic.exe, please open the file Cosmic.exe.Config and change the 1.5 to read 1,5 - This is a bug with how decimal points are handled by a Windows function.

Network Security & Whether to ProgPow

While listening to the Core Devs Meeting #54 this morning, I realized that the factual trade-offs around ProgPow need to be better defined so that we can truly hear the community's take on this issue. It is a lot to put on the core team, and everyone seems to want more participation in this debate. An audit of ProgPow is necessary, but it will not lead to a decision on whether to implement it or not. In talking about the trade-offs of ProgPow until the end of such audit, let's just assume it works as expected.
I'll start by saying that it has been extremely difficult and frustrating for me to understand the tradeoffs of ProgPow, despite being actively involved in the community. I can only imagine how difficult it might be for the average ETH stakeholder to have an opinion on whether ProgPow is a good idea or not.
The conspiracy theories that have surfaced around ProgPow have certainly not contributed to the debate, and I'd like to take this opportunity to focus on facts, not speculation.
If you just tuned in, a good place to start is the question what is ProgPow?
ELI15: ProgPow is a module based on CUDA to better parallelize specific functions of Ethash on Nvidia architectures and increase computational efficiency. My back-of-the-envelope math shows that, under ProgPow, GPUs mining ProgPow-Ethash would be 1.5x more efficient than Plain-Ethash. Also, ProgPow allows the algorithm's parameters to be programmatically changed to prevent an integrated circuit (in an ASIC) to have an edge on efficiency over commodity GPUs in the long-run.
ELI5: ProgPow makes GPUs more efficient and allows Ethash to change in a way that curbs the advantage ASICs have over GPUs in the long-run.
The issue(?) of decreased hashing power
EF Security Lead Martin Swende said in the call today that he expects ProgPow to cut difficulty in half, which would in turn lead to lower hashing power being allocated to the network. Since Plain-Ethash would have different parameters than ProgPow-Ethash, their hashrates are not comparable in terms of security. Think of Plain-Ethash and ProgPow-Ethash as different algorithms. Still, all else equal, a 50% decrease in difficulty "doesn't sound too good" as u/Souptacular put it in the call today. That is because, even though hashrates are not comparable, the aggregate amount of electricity required to potentially attack the network is decreased, meaning, the cost of an attack might be lower post-ProgPow. However, I also recognize that there are social factors that also need to be considered in the decision of implementing ProgPow.
Based on my conversations, hobbyist miners have a love/hate relationship with Ethereum.
Ethash's hardness to ASIC has brought to Ethereum a lot of individual miners and small operations who, through mining pools, contribute to a large amount of the current hashrate. Competition with larger operations is lower on Ethereum than say, Zcash, given the much decreased efficiency gains when using ASICs on Ethash. This is the "love" in the sentence above. The "hate" is the realization that the network will eventually adopt PoS and that, until then, block rewards will continue to decrease. This is painful, especially at current price levels. This coalition of smaller operations believes that the adoption of ProgPow would level the playing field even further and make mining Ethash more fair. Not adopting ProgPow may lead this coalition of retail miners to leave Ethereum. This is may be the main reason why large mining pools like Ethermine are pro-ProgPow. The worst-outcome-possible would be for these miners to fork their coalition out of the protocol.
The issue of ASIC centralization
Another argument pro-ProgPow that keeps popping up is that ASICs contribute to centralization, which has been an ongoing problem for Bitcoin and many other protocols that employ algorithms that are not as hard as Ethash. u/vbuterin has said in the past that he does not believe mining centralization concerns are as relevant to Ethash as other algos. And after surveying the Ethash ASIC market, I tend agree with him. It all seems to comes down to efficiency and the degree of centralization in the ASIC manufacturing industry. Ethash ASICs are only 2x more efficient than state-of-the-art GPUs; a much lower efficiency coefficient than SHA-256 ASICs, which are 1000x more efficient. There are now eleven different models of Ethash ASICs in the market, and three fiercely competitive manufacturers producing them (BITMAIN, Innosillicon and PandaMiner). Had BITMAIN been the only entity in the Ethash ASIC market, I would be more concerned about centralization, but that does not seem to be the case. Ultimately, we should remember that ProgPow does not eliminate existing ASICs from the market - it only makes existing GPUs more efficient on a relative basis. Also, the activation of ProgPow would not prevent these manufacturers from developing a ProgPow-compatible ASIC.
The most important factor to consider right now is network security.
Even more so because the PoW chain will be an integral component of the first stages of the new Serenity roadmap. PoS validators stake their funds on the PoW chain and, as such, the entire system relies on a sufficiently large number of miners to not abandon Ethereum. From my understanding, due to the use of Nvidia's CUDA, GPU miners running RX580s and RX Vegas (which are based on AMD) would not be able to mine ProgPow (please fact-check if I'm wrong). We don't know the proportion of miners running AMD versus Nvidia versus ASICs.
Core developers are focusing on whether ProgPow does what it is supposed to do, hence the focus on an audit, but that might not be the right question. The way I see it, the right question should be (assuming ProgPow works): in what scenario will network security be optimized in terms of cumulative electricity expenditure allocated to Ethash?

How do I mine Dogecoin?

How do I mine Dogecoin?
Let’s take a lucky guess that you’re here today because you’ve heard a lot about cryptocurrencies and you want to get involved, right? If you’re a community person, Dogecoin mining might be the perfect start for you!
Bitcoin was the first in 2009, and now there are hundreds of cryptocurrencies. These new coins (that operate on their own native blockchain) are called altcoins or alternative coins. One popular altcoin is Dogecoin. It can be bought, sold and traded, just like Bitcoin. It can also be mined!
So, what is Dogecoin mining?
You’ll know what hardware and what software you need to get started. You’ll also know whether or not Dogecoin mining is for you!
So, where would you like to start? The beginning? Great choice. Let’s have a quick look at how Dogecoin got started.
A (Very) Short History of Dogecoin
In 2013, an Australian named Jackson Palmer and an American named Billy Markus became friends. They became friends because they both liked cryptocurrencies. However, they also thought the whole thing was getting too serious so they decided to create their own.
Palmer and Markus wanted their coin to be more fun and more friendly than other crypto coins. They wanted people who wouldn’t normally care about crypto to get involved.
They decided to use a popular meme as their mascot — a Shiba Inu dog.

https://preview.redd.it/rymnyyz1iil31.png?width=303&format=png&auto=webp&s=f138e3fe56eef9c6b0e7f49b84fefc41fb83e5aa
Dogecoin was launched on December 6th, 2013. Since then it has become popular because it’s playful and good-natured. Just like its mascot!
Dogecoin has become well-known for its use in charitable acts and online tipping. In 2014, $50,000 worth of Dogecoin was donated to the Jamaican Bobsled Team so they could go to the Olympics. Dogecoin has also been used to build wells in Kenya. Isn’t that awesome!
Users of social platforms – like Reddit – can use Dogecoin to tip or reward each other for posting good content.
Dogecoin has the 27th largest market cap of any cryptocurrency.
Note: A market cap (or market capitalization) is the total value of all coins on the market.
So, Dogecoin is a popular altcoin, known for being fun, friendly and kind. It’s a coin with a dog on it! You love it already, don’t you?
Next, I want to talk about how mining works…
What is Mining?
To understand mining, you first need to understand how cryptocurrencies work. Cryptocurrencies are peer-to-peer digital currencies. This means that they allow money to be transferred from one person to another without using a bank.
Every cryptocurrency transaction is recorded on a huge digital database called a blockchain. The database is stored across thousands of computers called nodes. Nodes put together groups of new transactions and add them to the blockchain. These groups are called blocks.
Each block of transactions has to be checked by all the nodes on the network before being added to the blockchain. If nodes didn’t check transactions, people could pretend that they have more money than they really do (I know I would!).
Confirming transactions (mining) requires a lot of computer power and electricity so it’s quite expensive.
Blockchains don’t have paid employees like banks, so they offer a reward to users who confirm transactions. The reward for confirming new transactions is new cryptocurrency. The process of being rewarded with new currency for confirming transactions is what we call “mining”!

https://preview.redd.it/rcut2jx3iil31.png?width=598&format=png&auto=webp&s=8d78d41c764f4fe4e6386da4f40a66556a873b87
It is called mining because it’s a bit like digging for gold or diamonds. Instead of digging with a shovel for gold, you’re digging with your computer for crypto coins!
Each cryptocurrency has its own blockchain. Different ways of mining new currency are used by different coins where different rewards are offered.
So, how do you mine Dogecoin? What’s special about Dogecoin mining? Let’s see…
What is Dogecoin Mining?
Dogecoin mining is the process of being rewarded with new Dogecoin for checking transactions on the Dogecoin blockchain. Simple, right? Well no, it’s not quite that simple, nothing ever is!
Mining Dogecoin is like a lottery. To play the lottery you have to do some work. Well, actually your computer (or node) has to do some work! This work involves the confirming and checking of transactions which I talked about in the last section.
Lots of computers work on the same block of transactions at the same time but the only one can win the reward of new coins. The one that earns the new coins is the node that adds the new block of transactions to the old block of transactions. This is completed using complex mathematical equations.
The node that solves the mathematical problem first wins! It can then attach the newly confirmed block of transactions to the rest of the blockchain.
Most cryptocurrency mining happens this way. However, Dogecoin mining differs from other coins in several important areas. These areas are;
  • Algorithm: Each cryptocurrency has a set of rules for mining new currency. These rules are called a mining or hashing algorithm.
  • Block Time: This is the average length of time it takes for a new block of transactions to be checked and added to the blockchain.
  • Difficulty: This is a number that represents how hard it is to mine each new block of currency. You can use the difficulty number to work out how likely you are to win the mining lottery. Mining difficulty can go up or down depending on how many miners there are. The difficulty is also adjusted by the coin’s protocol to make sure that the block time stays the same.
  • Reward: This is the amount of new currency that is awarded to the miner of each new block.
Now, let’s compare how DogeCoin mining works compared to Litecoin and Bitcoin…
Mining Comparison
Bitcoin uses SHA-256 to guide the mining of new currency and the other two use Scrypt. This is an important difference because Scrypt mining needs a lot less power and is a lot quicker than SHA-256. This makes mining easier for miners with less powerful computers. Fans of Litecoin and Dogecoin think that they are fairer than Bitcoin because more people can mine them.
Note: In 2014, Litecoin and Dogecoin merged mining. This means they made it possible to mine both coins in the same process. Dogecoin mining is now linked with Litecoin mining. It’s like two different football teams playing home games in the same stadium!
Mining Dogecoin is a lot faster than mining Litecoin or Bitcoin. The block reward is much higher too!
Don’t get too excited though (sorry!). Dogecoin is still worth a lot less than Bitcoin and Litecoin. A reward of ten thousand Dogecoin is worth less than thirty US Dollars. A reward of 12.5 Bitcoin is currently worth 86,391.63 US Dollars!
However, it’s not as bad as it sounds. Dogecoin mining difficulty is more than one million times less than Bitcoin mining difficulty. This means you are much more likely to win the block reward when you mine Dogecoin.
Now I’ve told you about what Dogecoin mining is and how it works, would you like to give it a try?
Let’s see what you need to do to become a Dogecoin miner…
How to Mine Dogecoin
There are two ways to mine Dogecoin, solo (by yourself) or in a Dogecoin mining pool.
Note: A Dogecoin pool is a group of users who share their computing power to increase the odds of winning the race to confirm transactions. When one of the nodes in a pool confirms a transaction, it divides the reward between the users of the pool equally.
Dogecoin Mining: Solo vs Pool
When you mine as a part of a Dogecoin pool, you have to pay fees. Also, when the pool mines a block you will only receive a small portion of the total reward. However, pools mine blocks much more often than solo miners. So, your chance of earning a reward (even though it is shared) is increased. This can provide you with a steady new supply of Dogecoin.
If you choose to mine solo then you risk waiting a long time to confirm a transaction because there is a lot of competition. It could be weeks or even months before you mine your first block! However, when you do win, the whole reward will be yours. You won’t have to share it or pay any fees.
As a beginner, I would recommend joining a Dogecoin pool. This way you won’t have to wait as long to mine your first block of new currency. You’ll also feel like you’re part of the community and that’s what Dogecoin is all about!
What You Need To Start Mining Dogecoin
Before you start Dogecoin mining, you’ll need a few basics. They are;
  • A PC with either Windows, OS X or Linux operating system.
  • An internet connection
  • A Shiba Inu puppy (just kidding!)
You’ll also need somewhere to keep the Dogecoin you mine. Go to Dogecoin’s homepage and download a wallet.
Note: A wallet is like an email account. It has a public address for sending/receiving Dogecoin and a private key to access them. Your private keys are like your email’s password. Private keys are very important and need to be kept completely secure.
There are two different types; a light wallet and a full wallet. To mine Dogecoin, you’ll need the full wallet. It’s called Dogecoin Core.
Now that you’ve got a wallet, you need some software and hardware.
Dogecoin Mining Hardware
You can mine Dogecoin with;
  • Your PC’s CPU: The CPU in your PC is probably powerful enough to mine Dogecoin. However, it is not recommended. Mining can cause less powerful computers to overheat which causes damage.
  • A GPU: GPUs (or graphics cards) are used to improve computer graphics but they can also be used to mine Dogecoin. There are plenty of GPUs to choose from but here are a few to get you started;SAPPHIRE Pulse Radeon RX 580 ($426.98)Nvidia GeForce GTX ($579.99)ASUS RX Vega 64 ($944.90)
  • A Scrypt ASIC Miner: This is a piece of hardware designed to do one job only. Scrypt ASIC miners are programmed to mine scrypt based currencies like Litecoin and Dogecoin. ASIC miners are very powerful. They are also very expensive, very loud and can get very hot! Here’s a few for you to check out;Innosilicon A2 Terminator ($760)Bitmain Antminer L3 ($1,649)BW L21 Scrypt Miner ($7,700)
Dogecoin Mining Software
Whether you’re mining with an ASIC, a GPU or a CPU, you’ll need some software to go with it. You should try to use the software that works best with the hardware you’re using. Here’s a short list of the best free software for each choice of mining hardware;
  • CPU: If you just want to give mining a quick try, using your computer’s CPU will work fine. The only software I would recommend for mining using a CPU only is CPU miner which you can download for free here.
  • GPU: If you mine with a GPU there are more software options. Here are a few to check out;CudaMiner– Works best with Nvidia products.CGminer– Works with most GPU hardware.EasyMiner– User-friendly, so it’s good for beginners.
  • Scrypt ASIC miner:MultiMiner– Great for mining scrypt based currencies like Litecoin and Dogecoin. It can also be used to mine SHA-256 currencies like Bitcoin.CGminer and EasyMiner can also be used with ASIC miners.
Recommendations
You’re a beginner, so keep it simple! When you first start mining Dogecoin I would recommend using a GPU like the Radeon RX 580 with EasyMiner software. Then I would recommend joining a Dogecoin mining pool. The best pools to join are multi-currency pools like Multipool or AikaPool.
If you want to mine Dogecoin but don’t want to invest in all the tech, there is one other option…
Dogecoin Cloud Mining
Cloud mining is mining without mining! Put simply, you rent computer power from a huge data center for a monthly or yearly fee. The Dogecoin is mined at the center and then your share is sent to you.
All you need to cloud mine Dogecoin is a Dogecoin wallet. Then choose a cloud mining pool to join. Eobot, Nice Hash and Genesis Mining all offer Scrypt-based cloud mining for a monthly fee.
There are pros and cons to Dogecoin cloud mining;
The Pros
  • It’s cheaper than setting up your own mining operation. There’s also no hot, noisy hardware lying around the house!
  • As a beginner, there isn’t a lot of technical stuff to think about.
  • You get a steady supply of new currency every month.
The Cons
  • Cloud mining pools don’t share much information about themselves and how they work. It can be hard to work out if a cloud mining contract is a good value for money.
  • You are only renting computer power. If the price of Dogecoin goes down, you will still have to pay the same amount for something that is worthless.
  • Dogecoin pools have fixed contracts. The world of crypto can change very quickly. You could be stuck with an unprofitable contract for two years!
  • It’s no fun letting someone else do the mining for you!
Now you know about all the different ways to mine Dogecoin we can ask the big question, can you make tons of money mining Dogecoin?
So, Is Dogecoin Mining Profitable?
The short answer is, not really. Dogecoin mining is not going to make you a crypto billionaire overnight. One Dogecoin is worth 0.002777 US Dollars. If you choose to mine Dogecoin solo, it will be difficult to make a profit. You will probably spend more money on electricity and hardware than you will make from Dogecoin mining. Even if you choose a Dogecoin pool or a cloud pool your profits will be small.
However, if you think I am telling you to not mine Dogecoin, then you’re WRONG! Of course, I think you should mine Dogecoin!
But why? Seriously…
Well, you should mine Dogecoin because it’s fun and you want to be a part of the Dogecoin family. Cryptocurrency is going to change the world and you want to be part of that change, right? Mining Dogecoin is a great way to get involved.
Dogecoin is the coin that puts a smile on people’s faces. By mining Dogecoin you’ll be supporting all the good work its community does. You’ll learn about mining from the friendliest gang in crypto. And who knows? In a few years, the Dogecoin you mine now could be worth thousands or even millions! In 2010, Bitcoin was worthless. Think about that!
Only you can choose whether to mine Dogecoin or not. You now know everything you need to know to make your choice. The future is here. So, what are you going to do?

10 minute rule btc or all coins

i know bitcoin has a rule of 10 minutes you have to submit a share or you dont get anything i was wondering does all coins use the same 10 minute rule or is it just btc?
i am mining x16r and no matter what overclock settings i use it does not make a difference in the hashrate so i am wondering if x16r does not require overclocking because it does not have the 10 minute rule thereby you can get a share on some of the earlier cuda nvidia cards like the quadro 600 witch only has 96 cuda cores and is very unprofitable and would time out on btc.

Non-US English Windows Users: **If the program crashes or doesn't launch when you double-click Cosmic.exe, please open the file Cosmic.exe.Config and change the 1.5 to read 1,5 - This is a bug with how decimal points are handled by a Windows function. I will add a fix right away. This workaround will hopefully fix the issue for you in the meantime. :) You should not need to edit the Config file manually in any other circumstance- just use the Options->Configure... menu item to quickly get set up.
You can probably also change this setting in Windows' 'Region & Language Settings' > 'Additional Date, Time and Regional Settings' > 'Change Date, Time or Number Formats' > 'Additional Settings' > Decimal Symbol `.`
