I'm not talking about this starter kit; rather, I'm talking about laying the groundwork for some light Bitcoin mining using a RPi Model B. Block erupters aside, I wanted to buy a Pi and some other things for around $30 that has:
A USB hub for the erupters
A USB fan for cooling said eruptors
Class 10 SD card for holding mining software
I don't know a whole lot about RPi or BTC, but I think that this list is a good one. Short post shorter, I need your help on deciding what to buy. When the stuff comes in doesn't really matter. Just tell me what I could add, change, or remove from the list to make it better for mining. Thanks!
Hey everyone, sorry--n00b here--thanks in advance for any help and advice! I am thinking about getting a RPi to start/try mining BitCoin, if that doesn't take off I will make it into a vintage game emulator instead or try little home automation projects. Which model should I buy to start? Would a different model be better for one of these projects but not another?
Trying to set up RPi to mine bitcoin using Block Erupters, but nothing seems to be working correctly
Hey guys, so I'm trying to use my RPi (B+ model) to set up a rudimentary bitcoin mining rig, but nothing seems to work correctly. I've tried using cgminer on Raspbian Jessie, but cgminer seems to refuse to use the miner. Nothing shows up when I check my hash rate on Slushpool's website, the current pool I'm using. I have another microSD that I set up with minepeon, but every time I try to plug in my Block erupter (which is a dualminer Litecoin/Bitcoin miner), it keeps telling me that I don't have permissions to access the USB port that they are plugged into. I've googled various things and I keep getting closer to it actually working, but it still isn't showing any hash rate. Anyone tried something similar and had problems? tl;dr: Using RPi B+ to mine via ASIC block erupters, both with Raspbian Jessie and cgminer, and with minepeon, neither work correctly. Help?
Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)
I contemplated to wrote this for a long time, so it's finally time. As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall. So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide. I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research. I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works. So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing: sudo apt-get update && sudo apt-get upgrade Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it. So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
Now you can list files by:
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path]
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet)
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh
Now to run it, it's just:
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk. So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM. Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name]
Then press y and again wrote:
This process is going to continue where it was left off, so nothing is going to run from beginning. Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above. So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.
As an art project I want to set up a raspberry as a bitcoin miner with a twist: It will only mine when the difficulty factor is low enough to mine on a rpi, "a miner at the end of the universe" kinda idea. Obvious, it's hard to find much info about how to do this, any suggestions where to start?
I use bfgminer as a stratum proxy running on rpi and connected to my BTC full node. Few friends of mine are mining using my stratum, but the setup stopped working as soon as i updated Bitcoin Core to 0.18.0. All was fine with previous version 0.17.1. My rpi can reach rpc port and also authentication is fine. I use same credentials for a long time on a web service to display info about my node and it works. I didn’t not find in a changelog anything what could explain it. What could be the problem? Is there any other sw i can run as stratum proxy on rpi? Thx
Is there a niche for a small portable digital "typewriters"? (or the story of my keyboard experience)
Hello, MK Redditors. I'm here with quite an endeavour. But first, let me tell you a little (actually, a lot. lol) about myself. My name is Ilya (yes-yes, I love you all). I'm from Russia and I have cerebral palsy (nothing to worry about, it's just the way it is). Because of my creative nature, I always wanted to make something. When I was a little kid, my favourite toy was a LEGO set. I had literary a full bucket of it and was building cities, machines and all sorts of stuff, functional and not. Then the school years came... I did well in school (it was a special one for students with disabilities). The only problem was I could not write. I mean, yeah... I can write by hand (thanks to my parents, pre-school teachers and my first teacher in elementary school), but it's much much slower than the non-disabled people, and even my disabled classmates were outpacing me in writing by hand. In the elementary school it was all right, I tried to keep a pace. But by the 3rd grade (we have 4 years elementary, 6 years middle and 2 years of high school) it became apparent that I needed some extra help with that. We did not have iPads, or iPhones and even cellphones were a luxury back in the late 90s - early 2000s. So the school had a couple of electric (but not digital) typewriters for the students like me. Oh... That clicks... That feels... For a small 10 y.o. me it was huge noisy beast of a mechanical and electrical powers fused together, literally spitting the letters on paper and choking on itself when the jam occurred (which, frankly speaking, occurred quite often under my little unstable fingers). But anyway, I was writing faster and faster. I loved it. To be able to materialise my ideas onto something physical (a.k.a. paper), to be able to express myself through the written text, to make my world on paper. It was fascinating. It was like LEGO, but on a much bigger scale. Because this time I was expressing myself not trough premade pieces of plastic, but rather using the words, building blocks of society and culture. Around the same time, my parents got me my first PC - the outdated Win95 machine with fat tube monitor covered with "eye-protecting" film, floppy discs as the only means of transferring files and, obviously, no internet. Keyboard was much slimmer, but also cheaper. There were no... character to it. But hey... It was the COMPOOOTER! My, personal, with all the software and hardware to explore. Being quite curious child, I was exploring the broad world of Computing. I remember crashing the system a couple of times due to my "what will happen if I delete/run this" to the point of complete wipe of the HD, or messed up BIOS. The computer guy would then come with like 20 Floppies to reinstall the system. The pure childish curiosity and no fear of making mistakes... The golden years, indeed. The teenage years came in. I started to write poetry and songs. Because... well... hormones, love, hatred, broken heart and other teenage shite. OOTERS are becoming more powerful, KEEBS are becoming cheaper and shittier. One time I've completely worn off WASD claster (I loved Video Games. I still am, just don't have enough time to play them. The adult life got the best of me... lol) Then... well... Came the UNI-time... I've switched to Mac to be "more productive", plus the MacOS looked nice and Windows were starting to go downhill. With Uni came the tremendous amount of writing. The first year I typed my course notes on a touch screen of my iPad. Because it's portable and much lighter than notebook (laptop). Then I got myself the case with the keyboard. The shittiest keyboard of all... Small... Uncomfortable... Rubbery-domey... My Apple Wireless is not the best keeb, but at least bearable. But what other options I had, for real? I could bring Battleship-type of keeb for iPad... But I did not know that mechanical keyboards existed. Until recently. I've beed lurking this place for quite some time. And thanks to this wonderful community, I'll be getting my first mech very soon. It's quite the investment. We shall see if it pays out..... My other passion is programming and DIY electronics. I'm still a noob at it. But hey... Learning new skills is fun and good for your brain. I have built a 3D printer, a portable PC that I designed myself and a retro gaming console (on a RPi). So yeah... So... TL;DR of this long introductory section: I love writing (as you can probably tell by this wall of text), computers and DIY. That is my story so far. As you can see, the keyboards (at least for the way I see it) are becoming worse and worse, while PCs are becoming more commonly distributed. I mean EVERYONE's got a computer in one form or another, be it a stationary PC, a tablet PC or a smartphone. Plus, the devises are becoming "smart". The "smartification" of our devices is so common, that we don't know whether our smart fridge is secretly streaming our nightly snack for the whole Internet to watch or mining that sweet sweet Bitcoin for the North Korea while we are on a holiday. I'm thinking about my next DIY project. And since I've got my hands dirty in PCB design, I'm thinking of throwing together every skill I have and make... drum roll, please... __ The portable digital typewriter. __ Basically a smart mechanical keyboard. Something like Freewrite, but smaller and more portable and definitely cheaper. I'm thinking maybe a 40% layout with the Pi Zero W (even smaller version of a Raspberry Pi) as the brain. If I like the end result, I might as well make a small batch and sell it. So... My main question is this: Is there a market for such devices? Or is it just a gimmicky gadget that will be there for the LOLs? What are your opinions on such a device? I myself would see this as a small niche item for the disabled like me who is in need for the small and portable device to write on or the writers who don't like to carry the laptop and the mech keyboard with them. What do you, guys and gals of MKR, think about it? Once again, sorry for a wall of text.
NY SegWit2x signers can mine Bitcoin Cash without breaking their word (an open letter to miners)
This is my attempt of an open letter to the miners that signed the NY agreement in May and miners who think that SegWit2x is the saver way to scale on-chain. I get the feeling that you see yourselves obligated to stick with SegWit2x and continue mining on its chain because you singed the Bitcoin Scaling Agreement at Consensus 2017. You are not obligated to do so. Here is what you signed to do:
Activate Segregated Witness at an 80% threshold, signaling at bit 4
Activate a 2 MB hard fork within six months
Although it does not say so, it implies that this needs to happen on the bitcoin chain which has since transformed to the SegWit2x chain. But it does not say that you need to mine the SegWit2x chain indefinitely. Nobody could expect from you to keep the miners running if it is not in your economic interest. You could just turn them off and nobody would say that you broke the agreement. Switching to the Bitcoin Cash chain is the same. In a way you are shutting your miners on the SegWit2x chain off. You don't block SegWit activation and you don't block the 2x HF down the road. Meaning you do not break the agreement or lose face in doing so. You might want to stay on SegWit2x because of economic reasons. But you are not considering that the economy will follow the hashrate. Every BTC owner will own BCC. They will not lose any money if the majority hashpower will switch to Bitcoin Cash. And in the long run Bitcoin Cash will give miners more profit then SegWit2x thus it is in your interest to switch. When you signed the agreement in May I thought the SegWit and small blockers advocates would be happy. They got 100% of SegWit and we the big blockers made a huge compromise in going down from originally GB sized blocks with BIP101 to a mere 2MB with no additional increase in the future. This was an appeasement towards the UASF and Core advocates and giving them way more weight and say than they should have received. Because it looks as if at many (if not on every) conference they are a minority. But we immediately saw that it had no effect. UASF was going forward nevertheless and even now while having 100% of the blocks voting for SegWit they are still not happy and already plan the future without the 2x HF. Unfortunately your appeasement did not work. The SegWit2x path until the November HF will be full of hate, FUD, lies, etc. I have seen the recent interview with Roger Ver. He looked tired, angry and disappointed. I understand him. What I don't understand is why he (and maybe you) keep fighting an up hill battle against censorship and Core sheep on their terms when there is a way out. By moving your hashpower to Bitcoin Cash you change the terms by
showing that hashpower defines the rules (1 CPU 1 vote)
showing that enough is enough
leaving the FUD behind and let the small blockers have their SegWit chain with RPi nodes
finally getting back on track with scaling bitcoin as it should have been done back in 2016
not fearing the HF and lay the grounds of many more to come and thus keeping bitcoin competitive
We had XT, Classic, BU and we got closer every time. On August 1st we have ABC (giving us Bitcoin Cash) and it is time to break free. Please move your hashpower to Bitcoin Cash and make bitcoin what it was always supposed to be. In return secure your future and profit with more on-chain transactions and fees then you will ever get with the proposed L2 road map and self-crippling soft fork upgrades. Thank you! edit: fixed the formatting and typos
Hey, /EtherMining, I am currently looking for ideas for a project in my Computer Science class involving a Raspberry Pi. I figured crypto might be the right idea, since I already mine, but I'm unsure what I could possibly do with my Pi. I've already seen a few ideas online related to wallet storage but I'm curious if there's any "hidden" things I can do related to this. Have you guys had any success with a Raspberry Pi and your rig? Let me know.
It includes the description of Blockchain, bitcoin wallet, signature, cryptography etc. You will also be explained about the types of mining on the basis of different parameters such as hardware and number of people involved in the mining process. You'll also be briefed about the SHA, which is an algorithm used for implementing bitcoin mining. Following on from mining cryptocurrency using a Raspberry Pi, you can also use the device to stake cryptocurrencies. Cryptocurrencies that use Proof of Stake (PoS) algorithms instead of energy-intensive Proof of Work (PoW) algorithms bring the power back to end-users rather than the enormous mining pools. But, currencies like BitCoin have worked on a sliding scale, meaning it has become more difficult to mine a coin (and the value of the coin has risen). For that reason, mining with a Raspberry Pi has traditionally been counterproductive—it would take you years and years to even make up the cost of the Pi itself. -Mining them. Mining is the process of verifying transactions in the blockchain. As the whole of the Bitcoin system is decentralised, every transaction is publically viewable within what is called the blockchain. This blockchain contains every bitcoin exchanged between users so, as there is no central server, it has to be self governed. Pi is a new digital currency being developed by a group of Stanford PhDs. For a limited time, you can join the beta to earn Pi and help grow the network.
