Bitcoin mentioned around Reddit: [Serious] what kind of mining hardware should one invest in with about 1k of available funds for a passive income stream?? should one use usb(s), ASIC(s), FPGA(a), or GPU(S) in this age of the game wi /r/AskReddit
What I currently use for privacy (after almost 2 years of long investing into it)
New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG. We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

What is really happening in the bitcoin mining process?
April 30, 2020 | There’s more than just the sound of thousands of vacuums It is very easy to just silo the arcane bitcoin mining process as just a bunch of machines computing mathematical algorithms. Although for the most part this is true, and the veracity of this is not far off from the real truth, but what we see on the surface is not identical to what we see below the surface. Understanding bitcoin mining goes beyond the USB enabled ASIC miners we are accustomed to see on every thumbnail article we come across related to this industry. It’s easy to understand why newbies halt their understanding of bitcoin mining to just state-of-the-art supercomputers with cool flickering neon green lights. The following below is taken from the masterpiece of a novel, “Mastering Bitcoin”, by the great Andreas Antonopolous. As elegant as it sounds, its best to restate Andreas’ explanation of emergent consensus. “Satoshi Nakamoto’s main invention is the decentralized mechanism for emergent consensus. Emergent, because consensus is not achieved explicitly — there is no election or fixed moment when consensus occurs. Instead, consensus is an emergent artifact of the asynchronous interaction of thousands of independent nodes, all following simple rules. All the properties of bitcoin, including currency, transactions, payments, and the security model that does not depend on central authority or trust, derive from this invention. Bitcoin’s decentralized consensus emerges from the interplay of four processes that occur independently on nodes across the network:
Independent verification of each transaction, by every full node, based on a comprehensive list of criteria
Independent aggregation of those transactions into new blocks by mining nodes, coupled with demonstrated computation through a proof-of-work algorithm
Independent verification of the new blocks by every node and assembly into a chain
Independent selection, by every node, of the chain with the most cumulative computation demonstrated through proof of work”
The following is a scenario taken from the book as well which excellently demonstrates what is going on with a mining node and its corresponding connected miner machine: “A mining node is listening for transactions, trying to mine a new block and also listening for blocks discovered by other nodes. The arrival of this block signifies the end of the competition for block 277,315 and the beginning of the competition to create block 277,316. During the previous 10 minutes, while Jing’s node was searching for a solution to block 277,315, it was also collecting transactions in preparation for the next block. By now it has collected a few hundred transactions in the memory pool. Upon receiving block 277,315 and validating it, Jing’s node will also check all the transactions in the memory pool and remove any that were included in block 277,315. Whatever transactions remain in the memory pool are unconfirmed and are waiting to be recorded in a new block. Jing’s node immediately constructs a new empty block, a candidate for block 277,316. This block is called a candidate block because it is not yet a valid block, as it does not contain a valid proof of work. The block becomes valid only if the miner succeeds in finding a solution to the proof-of-work algorithm. These specialized machines are connected to his mining node over USB. Next, the mining node running on Jing’s desktop transmits the block header to his mining hardware, which starts testing trillions of nonces per second.” That is essentially the process of what a miner machine and a mining node is going through each every second it is hooked up to the network. Of course this is just a high level overview with a bland taste but one could go more in depth by reading the book mentioned.

Building an Ethereum Mining Rig (13 GPU) - 4th part
Third update to the guide "Building a Mining Rig for Ethereum". The absolute first guide to building a RX Vega 64 8gb 13 GPU Mining Rig. Reading this guide to building a 13 GPU Ethereum mining rig requires adequate knowledge of building and running an Ethereum Mining Rig. We therefore recommend a previous view of our Guide to build a Mining Rig and related updates. Let's immediately list the hardware used: - Asus Mining Master X370 mainboard - Core i5 Coffee Lake CPU - 480 or 500GB SSD - 32Gb Ram - 13 GPU RX Vega 64 8Gb - 3 x 1000W power supplies - 1 1200W power supply - 8Gb USB stick In this guide we will obviously not explain how to mount the hardware of a Rig. The only notes we wish to underline are the following: - the 1200W power supply must be the primary one on which to connect 4 GPUs and the video output for the monitor - all the risers, as well as obviously the GPUs, must be powered through the 8-pole connections of the power supplies. We strongly advise against the use of 6-pole ports. Therefore, have the appropriate number of cables available for all connections. Risers can also be powered in pairs. - the model of the video card used is the Asus Rog Strixx Gaming RX Vega 64 8Gb The operating system is Windows 10 updated to the latest version available. The tool for creating installation media is available at the following link https://www.microsoft.com/it-it/software-download/windows10 to be able to use the USB key as a launcher for installing Windows 10 . With the Asus Mining Master, the GPU risers can be connected directly to the motherboard via the USB cable, thus making one of the small components of the riser kits unusable. After making all the connections on the motherboard, check that all GPUs are highlighted in green when the PC starts up. If not, move the USB cable on the motherboard one position. It may take at least 2 or 3 attempts. Ethereum mining with 13 GPUs Having solved this possible small inconvenience, let's proceed with the installation of the AMD Adrenaline 2020 drivers, always updated to the latest version, relating to the RX Vega Series. If you want to proceed with more caution, the advice is to disconnect all the GPUs (remembering the locations of the USB cables) except one before installing the drivers. The mining will be carried out on the Ethermine pool, our favorite, using the Claymore 15 software. Once the download is complete, you will have to unzip the folder on the desktop and open the start.bat file contained in the Claymore folder using Notepad. The procedure is the usual one: delete the content and copy-paste the following command string: start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker" EthDcrMiner64.exe Where EthDcrMiner64.exe is the executable, -epool indicates the pool to mine and its port, -ewal is the wallet address and -epsw is the password that we leave blank (X). In place of "your wallet address" you will have to put your Ethererum wallet and instead of worker you will enter an identification number in case you plan to build more RIGs (such as RIG1, RIG2, etc ...). At the following link, many other useful commands for your Rig: https://github.com/Claymore-Dual/Claymore-Dual-Miner Try to run mining and check that the system is stable. In the Payouts section, after a few minutes of mining, you can decide the minimum amount of Ether to be sent to your wallet by simply entering the IP address of the RIG. We performed the mining directly on the Ethereum address of the Exodus wallet. Coinbase is not supported. Overclocking with OverdriveNTool Let's proceed now with the download of OverdrivenTool at the following link: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/ For those unfamiliar with it, we recommend reading our software guide. For those who do not intend to experiment or do not completely trust their software experience, at the following link you can view the settings on the parameters of the GPUs and the RAM of the GPUs - and other small tricks - to obtain the best possible performance without forcing the cards too much. video. On our Youtube channel (subscribe numerous !!!) you will now be able to see the video relating to the start of mining and the one concerning the stabilization phase. To better cool the Rig we have also installed fans for the extraction of heat as caution is never too much. Moreover, there is also an aesthetic gain. Conclusions on the guide to build a 13 gpu ethereum mining rig. Finally, we conclude this guide by reporting what everyone was waiting for (we do not say how long we had to wait before obtaining this result) the video link complhttps: //www.youtube.com/watch? V = k53XZn3zc9I & t = 61seto del Rig e del Mining . We remain available for any advice, both on pools, on yield and on consumption.

Hi all! I am looking for a watchdog for my rig which is running under smOS from a pendrive. I can hardly find any information about them. Can it restart my rig if the system is on a pendrive, not on a HDD or SSD? Does it need any driver installation or just plug and play? Is there any difference between the red, black and green ones? black red green Which one do you recommend or anything else for substitute?
What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
I want to play Warzone and (soon) Cyberpunk 2077 on the best possible settings, with the ability to stream on Twitch.
What is your maximum budget before rebates/shipping/taxes?
Ideally, I want to be between $2000-$2500, but am financially willing to go up to $3000.
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.
I am in no rush to buy the PC this week or this month. If I should wait for new processors and video cards that will be released in the fall, then I'll do that.
What, exactly, do you need included in the budget?
The best parts to support the highest video settings on a 4K monitor. CPU, CPU cooler, Mobo, GPU, PSU, Hard Drive, Case, Windows OS, additional USB ports, all that stuff
Pretty much everything but a mouse and keyboard.
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?
US - no MicroCenter location near me
If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
Just the mouse and keyboard
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
I have no desire to overclock
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 definitely want at least a 1 TB SSD drive (ideally 2 TB's), but the other words are things I don't know about so I have no clue. Whatever will help me have the best gaming/streaming performance for my budget.
For $3000, I just want the best possible gaming & streaming setup I can get. I don't do video editing, or Bitcoin mining, or any of that. I want to play and stream games, stream videos, and browse the Internet with it.
What type of network connectivity do you need? (Wired and/or WiFi) If WiFi is needed and you would like to find the fastest match for your wireless router, please list any specifics.
I have a powerline adapter connection, so I'll need an Ethernet port
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 want LED lighting, ideally blue and red
Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?
Yes, just a basic Win10
Extra info or particulars:
I want this PC to be built for me. I've built my own PC a few years ago and it took way longer than expected and received faulty hardware, so I will gladly pay extra to have someone else do it for me. Just the cable management alone is something I'm willing to pay an extra few Benjamin's for. For the aesthetic, I would like the case to be see-through with LED lights inside, with a white case.

We’ve been working on a new product release for a year and want to hear your opinions on the product. Read on for product information and our vision for hardware wallets.
TL;DR Key features of Cobo Vault 2nd gen we are going to launch:
QR code air-gapped
Totally open source: Including firmware of the Secure Element
PSBT support and compatibility with other wallets
Fingerprint authorization to prevent password leak
Detachable battery to prevent battery corrosion and AAA support
Bitcoin-only firmware option
Hey bitcoin! I'm Lixin, a longtime Bitcoiner and creator of Cobo Vault. I come from a background in the electronic hardware industry, and experienced one of my products being featured in Apple Stores around the world. Although my interest goes back to 2010, my career intersected Bitcoin when Discus Fish (CEO of Cobo) invited me to help build Cobo’s hardware product line. Discus Fish is also the co-founder and CEO of f2pool, one of the largest mining pools currently in the world, and one of the earliest advocates of bitcoin in China. Back in 2018 we built our 1st generation Cobo Vault hardware wallet. As we had strong ties to miners in China, we naturally designed the 1st gen with them in mind. For those who are not familiar with the mining industry in China, mining farms are nearly always built in very isolated places where there is very cheap wind or water electricity. As the miners would take their storage into these isolated regions, we needed to maximize the durability of the device in addition to its security. We used aerospace aluminum rather than plastic and made it completely IP68 waterproof. We also gave it a hardshell metal case you can put it in, which is IK9 drop resistant and passes the American military durability test MIL-STD-810G. As for the electronic components inside the device, in order to maximize security, we made it as air-gapped as possible with QR codes. We see this as an important choice because USB cables and Bluetooth are not transparent and have a bigger attack surface. With QR codes you can see exactly what is going on and do not have to connect to a laptop which could have malware on it. QR code interaction needs a camera and a more complicated system which needs to be supported by high-level chips. All these come with a cost, and the 1st generation isn’t as accessible for average hodlers. For more details on the product, visit here. Things changed last year when I went to Bitcoin 2019 and talked to lots of hodlers in the States. I found that 95% of them don’t care about durability. I asked them if they were afraid of their home being flooded or burned down in a fire. The answer is - yes, they are afraid of these things, but see them as very low possibilities. Even if something were to happen, they said they would just buy another HW wallet for 100 dollars. From these conversations, it became more and more clear that the position for miners and hodlers is totally different. After coming back from that conference, our team began the almost one year journey of designing our 2nd gen product. It compromises on durability but doesn’t compromise on security. We designed the 2nd gen product all around a normal hodler’s needs. Obviously hodlers share some common needs with miners:
Hodlers want a more air-gapped solution so we took the legacy of QR code data transmission between your hardware wallet and the companion app from the 1st gen rather than using USB or Bluetooth.
A Secure Element is the strongest wall of protection from physical attacks. The 2nd gen will also have a Secure Element.
Some hodlers may touch their hardware wallet once every several months. With this time period, the battery could be a significant weak point. * The 2nd gen also continues the legacy of a detachable battery to prevent battery corrosion damage. In case the battery dies someday, 2nd gen will also support AAA batteries.
The 2nd gen also keeps the 4-inch touch screen. A touchscreen significantly increases ease of use - you don’t need to suffer from tiny buttons and little screens anymore. It also significantly lowers the possibility for human error, which is one of the biggest reasons that people lose their assets.
Continued other features like the self-destruct mechanism, which prevents side-channel attacks, and Web Authentication, which prevents supply chain attacks.
If you'd like to read more about these features, check out our blog posts here. Aside from these legacies from the 1st gen, our 2nd gen product will have some other big improvements:
With our 2nd gen we will open source the whole codebase when we launch in late Apr - including the firmware of the Secure Element. We are the first hardware wallet - also maybe the first electronic product with SE - to have open sourced the firmware of the SE. With the open source firmware code, you can see: Random number generation/master private key generation/key derivation/signing process all happens within the SE and your private keys never get out of the SE (maximizing protection against physical attacks).
At the Bitcoin 2019 conference half the hodlers I met told me they own multiple hardware wallets which they use on the go. So we added a fingerprint sensor you can use to authorize your transactions without typing in your password. No need to worry about surveillance cameras when using your hardware wallet in airports.
We will also support PSBT (BIP174) so that the device will be compatible with 3rd party wallets like Electrum or Wasabi Wallet in case people have need for using Cobo Vault with their own node or coinjoin. Also multisig between Cobo Vault and other wallets will be realized to prevent single point failure with a single brand of hardware wallet.
By sacrificing the durability of the device and its aluminum body/protective case and waterproof rating and lowering production costs, we successfully controlled the price under 200 USD. We wanted it to be at a price point most people in the community would see value in.
Personally, I am a bitcoin maximalist and also a big fan of the KISS principle. We will also release a BTC-only firmware version for people who want to minimize the codebase for less of an attack surface. Thank you for reading until here. More details like final price would be released later when we officially release the product in late Apr. Any suggestions or questions are welcome. Also you can find me @CryptoLixin or @CoboVault on Twitter! Ears are widely open!

All the benefits of running on a Pi, silent/fanless, low power (approx 15w) for 24/7 node, low cost.
Headless (No need for extra monitor,keyboard,etc) and connect via Ethernet or WiFi**
Background: I've been making nodes for other coins for a few years to learn about some crypto basics. It got a bit of interest for I have a site https://PiNode.co.uk but recently far more advanced projects have come on the scene (such as RaspiBlitz for Bitcoin) which was so far superior there was no sense pursuing it . However there are benefits for Monero users running their own node and we didn't have that quality of plug and play node. So I've been giving it a go and this is the result. The Future of PiNode-XMR: First of all project needs feedback to continue, I don't know what to develop and introduce unless people say what they don't like, do like or want. Second, it'd be great if anyone else in the Monero community would like to get involved, we have a great group and I'm sure there is an aspect of this project someone takes an interest in. Please get in touch. Like if there are any budding website designers in our midst the UI is the last module of this project that isn't open source, it's from a template and I've put it together best I can but...throwing that out there :) I'd be nice if the monero community could completely own this project, completely open source. Finally, I know that now there is more choice on the single board computer market and although the Raspberry Pi is popular it may not be the best hardware choice. So the next plan is to rather than make disk images that are hardware specific, to instead make scripts that are based on an OS ( probably Debian ). This way this project can be built by anyone using a single command onto Pine64, Odroid, Bananapi or any old laptop/pc with Debian for thier full node. Thanks for taking an interest and readingDan The "Advanced Settings" page from the UI for a bit of colour after all that text: https://preview.redd.it/4pqg5mcqr6941.png?width=1340&format=png&auto=webp&s=aa1f9ee176746ea064c8e8573ba04ee864ab5bc3 Edit: Added download link to this page too. Corrected image layout. Edit2: Added hash of image. And note it's also possible to flash the image directly onto a USB drive with a program like Rufus and not insert a MicroSD at all. You'll need to then manually expand that partition to the size of the drive, but may be useful to know.
Hey shibes, I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts! Feel free to add information to that thread or correct me if I did any mistake.
You downloaded the core wallet
Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here. Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.
You downloaded a GPU/CPU miner
Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!
Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain." - langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!
Mining solo versus pool
So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.
Buying an ASIC
You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...
You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.
Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc. Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same. Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.
Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!
Folding at Home (Doge)
Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much. Thanks for reading _nformant
I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!
Requirements: 1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does. **Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc* So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though. After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there. Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly). I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01 Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!! -----How To Do This Yourself: Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money. Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses. Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!) Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!! https://cryptotabbrowser.com/8557319 Links to Picture Proof http://imgur.com/gallery/P13bEsB
White Paper, Miner, Pizza … | "Old Objects" in the Cryptocurrency Museum
https://preview.redd.it/giu1ssilga151.jpg?width=900&format=pjpg&auto=webp&s=41510785ccdc0d99544ec74229f62427d1c0ce3e Museum has played the role of a time recorder. Talking about bitcoin, more than ten years has passed since the creation of it. Although it is uncomparable to the stock market with a hundred years of history, during the ten years, in the different stages of the development of bitcoin and blockchain have continuously poured in geeks, miners, speculators, newbies, leaving keywords such as sudden rich, myth, scam, belief, revolution, etc. There are also many “old objects” with stories in the “Museum” of the cryptocurrency realm. On Museum Day, let ’s review the stories brought by these “old objects”. The First Digital Currency White Paper — Bitcoin White Paper On Oct. 31, 2008, Satoshi Nakamoto released the Bitcoin white paper — A Peer-to-Peer Electronic Cash System in the cryptographic mail group where he belongs, and Bitcoin was born since then. A white paper is a document that explains the purpose and technology used in cryptocurrency. Usually a cryptocurrency uses the white paper to help people understand what it provides, and it is also an important information channel for investors to understand a project. Therefore, the level of the white paper affects people’s confidence towards the coin. In a word, in the cryptocurrency and blockchain industry, the value of a white paper is equivalent to that of a standard financing speech. The white paper plays a vital role in this emerging market. The First Public Bitcoin-Physical Transaction — Pizza Since Satoshi Nakamoto mined the Bitcoin genesis block on January 3, 2009, Bitcoin has only been spread among the small crowd and has not realized its value. Not until May 22, 2010, Bitcoin enthusiast “Laszlo Hanyecz” bought a pizza coupon worth $25 with 10,000 bitcoins. This is the first public bitcoin-physical transaction. Bitcoin has its price with 0.3 cents per bitcoin. This day has also become the famous “Bitcoin Pizza Day” in Bitcoin history. Bitcoin as the imagination of the financial system has more practical significance. The tenth anniversary is coming. How will you commemorate it? Will you buy a pizza? The First Digital Asset Exchange — Bitcoinmarket.com After the birth of Bitcoin, in addition to mining, the only way to get Bitcoin in the early days was to conduct transactions on forums or IRC (commonly known as Internet Relay Chat). However, this method involves both long transaction time and great security risk. In March 2010, the first digital asset exchange — Bitcoinmarket.com launched. However, due to lack of liquidity and transaction depth, it disappeared soon after its establishment, but Bitcoinmarket.com opened the era of the operation of the cryptocurrency realm exchange 1.0. On June 9, 2011, China’s first Bitcoin exchange — Bitcoin China (BTCChina) launched. Its founder, Yang Linke, translated Bitcoin into Chinese “比特币” for the first time. In 2013, China’s bitcoin trading entered the golden age, and exchanges sprung up. China monopolized more than 90% of the world’s bitcoin transactions. Now, if the top three exchanges Binance, Huobi Global, OKEx are the Exchange 2.0, then the index exchange represented by 58COIN called the 3.0 version, leading the trend. The First Generation of High-Performance Miner — ASIC Miner When Satoshi Nakamoto created Bitcoin, the only way to get it is to use computers (including home computers) to mine, mainly relying on the CPU to calculate. However, as the value of digital currencies such as Bitcoin has become higher and higher, mining has become an industry with the competition is getting fiercer, accompanied by increasing difficulty of mining. Therefore, hardware performance competition starts. In July 2012, the genius Jiang Xinyu (Internet nickname is “Friedcat”) from the junior class of the University of Science and Technology declared at the forum that he could make ASIC miners (chips). As far as mining computing power is concerned, ASICs can be tens of thousands or more higher than the same-generation CPUs and GPUs. At the beginning of 2013, Zhang Nanqian (Pumpkin Zhang), a suspended doctoral student from the Beijing University of Aeronautics and Astronautics, developed the ASIC miner and named it “Avalon”. In June 2013, the Friedcat’s miner USB was finally released, and it maintained 20% of the computing power of the entire network. At the end of 2013, Wu Jihan, used the tens of millions yuan earned from Friedcat through investment, worked together with Jenke group, to develop the Antminer S1. Since then, the miner manufacturer Bitmain began to enter the stage of history. It is no exaggeration to say that Friedcat and Zhang Nangeng have opened the domestic “mining” era. The Birthplace of China’s Bitcoin — Garage Coffee It is not only the “old objects” that record history, but also a place that everyone in the cryptocurrency realm aspires to. Guo Hongcai once said, “Without no The Garage Café, there will be no cryptocurrency realm today. Since it is a very mysterious place that all waves of people from the café joint together to create today’s digital asset industry. ▲ In March 2013, American student Jake Smith successfully purchased a cup of coffee at The Garage Café with 0.131 bitcoins. This move attracted the attention of CCTV, and it conducted an interview. Indeed, The Garage Café is the world ’s first entrepreneurial-themed coffee shop. It has been legendary since its establishment in 2011. The Garage Cafét is not only the core coordinate on China’s Bitcoin map, but also the birthplace of the Chinese cryptocurrency circle, where digital asset realm tycoons including Guo Hongcai, Zhao Dong, Li Xiaolai, Li Lin have made their ways. The development of digital currency is only 11 years old. Through these “old objects”, we review the various stories of this wave of technology together, hoping to help you understand the development process of the digital currency field. Meanwhile, I also remind all practitioners to use history as a mirror and forge ahead.

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.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
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.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
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.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
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).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
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.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.
Where can I buy bitcoins?
BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash. Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. Bitseed is an easy option for getting set up. You can view the global node distribution here.
Just like any other form of money, you can also earn bitcoins by being paid to do a job.
You can also earn bitcoins by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoins for a small fee (requires you to already have some bitcoins)
The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
1,000 per bitcoin
SI unit for milli i.e. millilitre (mL) or millimetre (mm)
1,000,000 per bitcoin
SI unit for micro i.e microlitre (μL) or micrometre (μm)
1,000,000 per bitcoin
Colloquial "slang" term for microbitcoin
100,000,000 per bitcoin
Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

If you decide to post a question in /Bitcoin, please use the search bar to see if it has been answered before, and remember to follow the community rules outlined on the sidebar to receive a better response. The mods are busy helping manage our community so please do not message them unless you notice problems with the functionality of the subreddit. A complete list of bitcoin related subreddits can be found here Note: This is a community created FAQ. If you notice anything missing from the FAQ or that requires clarification you can edit it here and it will be included in the next revision pending approval. Welcome to the Bitcoin community and the new decentralized economy!
Let me start this off with this is NOT a comprehensive, end-all-be-all guide to 'how to setup a livestream.' This is simply the workflow/setup I've come to use over 4 years of on and off streaming on Twitch. Hopefully it can help some of yall out that are (finally XD) joining the livestream world. *I only stream on Twitch using OBS, so this will be specific to Twitch and OBS; I have not tried YouTube, Facebook, Instagram, or any other platform or streaming software, but the basic outline is kind of there. Hardware: 2x 1200's, Rane TTM57sl mixer with Serato Scratch Live, Samsung laptop, Behringer Xenyx 802 USB mixer, Shure SM57 mic, Pansonic GH2 or Logitech webcam (depends on if I'm using green screen or not), and then my gaming PC is my streaming PC. For speakers, I have a Yahama receiver running a 5.1 system that I use with my gaming/streaming PC. It's not the best setup for DJ'ing necessarily, as the receiver can add quite a bit of latency, but if there is any now, I barely notice it. I run the receiver in 5 channel stereo, and turn off any signal processing that I can. Audio setup: I run 1/4" out of the booth outputs on the TTM57 into the Behringer mixer (this is for the stream audio). Then I have RCA -> 1/8" from the aux out on the TTM57 into the aux input on my receiver for my 'monitors.' I run the mic (XLR) into the Behringer mixer as well. The Behringer connects via USB to my stream PC. Camera setup: I either use an HDMI to USB3.0 capture card with my GH2 or a Logitech USB webcam. All it takes is plugging it into the stream PC. Easy enough. OBS setup: There are a TON of YouTube and written tutorials to setup OBS, but they generally focus on gaming and not so much DJ'ing. I won't go into too much detail, but will point out stuff more particular for DJ'ing. This is my main OBS screen. Have everything plugged in and turned on before you open OBS to make sure it picks up your USB devices (USB mixer and camera). Should go without saying, but also make sure you have your drivers installed for the devices. [Imgur](https://i.imgur.com/b2zJazj.png) The only audio I want outputting to the stream is from the Behringer mixer, so the desktop audio and camera audio are muted. Aside from the camera and mixer, all of the other sources in my source window are optional. (If you're curious as to why Winamp is in there, I can add details on that in a later post) Output settings: [Imgur](https://i.imgur.com/p2mIfvC.png) Video bitrate will depend on your ISP, your upload speed, and your streaming PC hardware. I've had to drop mine down to 2500kbps from my usual 3500kbps recently. I guess with everyone at home using the interwebs, my connection seems a lot more unstable than even a month ago. I set the audio bitrate to 320kbps, but I think Twitch ends up compressing it to 192kbps for viewers. Recording settings are optional, I only recommend streaming and recording at the same time if you have a decently powerful streaming computer. Better to record just the audio in your DJ software to upload the mix later. Twitch will mute any replays with copywritten material, so I upload to Mixcloud for archiving. I run the mic through the Behringer mixer versus the mic input on my Rane mixer because I talk to chat, and it's annoying listening back to mixes with me yammering through parts. My GPU recently kicked the bucket (still works on default Windows drivers...which has caused some bottlenecks when it comes to streaming, but I can still do it) so for now I'm using software encoding, but if you have the option for hardware encoding, use it. Video Settings [Imgur](https://i.imgur.com/2AjjHnL.png) Leave your base canvas at 1920x1080, but you want your output at 1280x720. I haven't really noticed a difference in the various downscale filters, but bicubic is what I use. 30fps is best for your viewers, as it's less demanding than running 60fps, but that's really up to you. Twitch: Twitch takes some getting used to; whether it's the website itself or the community/culture. The music community is very welcoming (especially now), and I encounter far less trolls there than in gaming channels. There's a lot of people there now trying to figure everything out, so don't feel like you're late to the party. If you want to try to make some money, you'll want to setup a donation site. Can be a simple PayPal link, Bitcoin link, or you can use something like streamelements or streamlabs. Those two extensions add other things like chatbots, commands (ie: a viewer can type !mixcloud in my chat will send a message in chat with my Mixcloud link), followesubscribedonator notifications. All of those are customizable, but I'd recommend just using the default stuff before making custom notifications and such. It can be a bit of a time sink..but then again I guess we got nothing but time right now. After you get up and going with a few streams, set your sights on reaching affilate. It's not that difficult to get, nor do you lose it if you don't keep up with the requirements to get it. You can then make custom channel emotes (again, another time sink, or there are a ton of artists out there that can make them for you) and accept subscriptions and bits. Twitch is owned by Amazon, so if you're a Prime member, link your Amazon account and you get a free subscription you can give to one streamer per month. It doesn't auto renew, so you can change it every month, but it is a nice 'gift' to give to streamers to help support them. Dark Sith Lord Bezos does take 50% of the $5/month cost of a base subscription (whether a Prime sub or paid for), so if you really want to help a streamer, use donations. But if you already have Prime, may as well throw the free sub around to someone. At the end of your stream, you can 'raid' another streamer. All it is is taking your viewers and dumping them into the channel of another streamer. I generally try to find other DJ's that are playing the same/similar genre that I think my viewers would stick around for; or just other DJ's I like. Then there's 'hosting.' That is when you are offline, but your channel is playing another stream. There are auto-host settings so that you don't have to manually host channels while you're offline. Between being raided (it's pretty much random and up to other streamers; don't beg) and raiding others, it's kind of the best way to get your channel out and exposed. But, don't make it about view counts or followers. Do it because you want to mix, no other reason. The music section has all of a sudden been saturated by DJ's/record labels due to the pandemic; there's a lot of people new to Twitch who don't know there's a bunch of other DJ's in the music category, so just keep going and you'll find an audience. Other thoughts: I love streaming on Twitch. I've done several 6+ hour streams in my time there. If you come from only playing out live, it's a big adjustment. There's no crowd energy to work off of; sometimes chat can give that to you, but it can be hard when you're just in your room by yourself. I personally find it hard to mix heavieharder stuff for more than 30-45 minutes at a time, so a lot of my mixes have been more chill and kind of downtempo as I can stay in that vibe for longer periods. I've met a lot of really awesome DJ's in my time there, and it's great seeing so many more looking for a creative outlet now that we're on global quarantine. Hopefully after some semblance of normality is restored, people will continue to livestream and the viewers keep coming back. I know this has been a giant wall of text, so apologies, but hopefully it gives someone something to go off of. Let me know if anyone has any specific questions or needs clarification on anything. Happy streaming!
