Bitcoin Mining on Your Raspberry Pi : 6 Steps - Instructables
How To Build A Raspberry Pi-Based Bitcoin Mining Rig ...
Yes, You Can Mine Cryptocurrency on Your Raspberry Pi ...
For discussion about Litecoin, the leading cryptocurrency derived from Bitcoin. Litecoin is developed with a focus on speed, efficiency, and wider initial coin distribution through the use of scrypt-based mining.
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. It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for 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. You can even run a node on a Raspberry Pi.
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 scaling - On chain transaction fees depend on network demand and how much priority you wish to assign to the transaction. Most wallets calculate on chain fees automatically but you can view current fees here and mempool activity here. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, a second layer scaling solution currently rolling out on the Bitcoin mainnet.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply memorizing a string of words for wallet recovery (while cool this method is generally not recommended due to potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for new users due to ease of use and additional security).
Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) 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 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, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger or ColdCard is recommended. Alternatively there are many software wallet options to choose from here depending on your use case.
If you prefer to let third party "Bitcoin banks" manage your coins, try Gemini 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.
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 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.
As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".
Where can I spend bitcoins?
Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.
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. If you would prefer to keep it simple there are several good options. 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:
one bitcoin is equal to 100 million satoshis
1,000 per bitcoin
used as default unit in recent Electrum wallet releases
1,000,000 per bitcoin
colloquial "slang" term for microbitcoin (μBTC)
100,000,000 per bitcoin
smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Welcome to the Bitcoin community and the new decentralized economy!
I’m a commentator for a tournament of nightmares. I’m not sure the participants are willing.
You’d think being a psychiatric ward for 38 months would be enough to deter a guy from ever going back to a sport that involves watching human beings at the height of their physical prowess beat the living shit out of each other. Sometimes regulated, sometimes not. But, here I am, fresh outta the loony bin and reading the most unusual advertising slogan I’d ever laid eyes on; “The most terrifying tournament has come around once again! Conquer your fears in theNFC*…* literally.” This was the business card that accompanied my black envelope as it was handed to me on the discharge ward by a well dressed and gangly fella with an uncomfortable wide smile. He didn’t say much of anything, just that his name was “Watson” before bowing and holding up the envelope. “Heh, like the butler, right?” I said, taking the envelope from his plasticine hands. His smile ripples across his face and he nods slowly, his perfect hair unmoving in the strong wind before he turns on his heel and walks back to the black sedan. The cold air chilled my bones, and I pulled the medical bracelet from my wrist, grimacing at the marks underneath before following Watson to the Sedan and hauling my luggage into the trunk before setting off, not knowing how I came to even be there in the first place. I guess right now, that doesn’t really matter. What matters is where I am now and what I’m doing. "blood strewn across the canvas, frayed brain matter sailing across my head and splattering against the wall, a woman standing in a pool of blood as the deformed creature twitches on the ground" My name is Sal “Motormouth” Sabotta, I’m a sports commentator by trade. Be it combat sports, pro wrestling, death-matches or martial arts tournament, I’ve done it all. I won’t lie; Work can be hard to come by. I’ve spent months struggling for rent and resorting to less tried-and-true commentary methods in order to survive. That has, at times, involved trying my hand at some of the more underground competitions; unregulated fights, sick, illegal games bet on by people on the dark web and worse… Things I’m not going to detail here. Things I’m not proud to have taken a hefty pay-check for from greasy, sweaty fucks in Armani tracksuits and stinking of cheap booze and coke all the way up to well-dressed bitcoin farmers in their 20s who probably own child slaves. In short, I’m no stranger to the grim underworld or the secrecies with which they conduct their work. I see money and an easy way to make it with my voice; I don’t ask questions. So when I received an email the day of my discharge from the hospital and I’m told “you’ll receive a letter from Mr. Watson, take it and follow the instructions to the venue. Pay up front as agreed.”, I don’t question it. Especially when the note is personalised, and the doctor says my medical fees were covered. We drove past numerous landscapes, vistas and neighbourhoods before veering off into an industrial estate and entering an underground tunnel. Half a mile in, Watson stops the car and peers back, smiling. He directs a thumb to the service door in the side tunnel and rubs his neck, a scar running from ear to ear. Was he a former fighter? Gangster? I sighed and got out, still in my medical gown and hauling ass to the door. It opened before I could reach out and a tall, muscular woman in her late 30s greeted me with a smile. She was imposing, powerful in her gait, a black eyepatch with several seals adorning the sides accompanying a thick scar down her face did nothing to stop her beauty. She wore a tank top with a black cloak with white fur on the tops and sleeves, a thick black chain clasp around the neck. I won’t lie; she looked badass. Terrifying, but badass. “‘Bout time ya showed up, Sabotta!” She grinned and put a cinderblock of a hand on my shoulder. I’m 5’10 and 180lbs, but she made me feel like a child in front of her. The power emanating from her fist was unbelievable. “C’mon, the trial match is starting and I don’t want no tourney without a broken in commentator! You gotta know the ropes of this place!” “You know your driver was standing right outside when I was discharged, right? Couldn’t think to give me an extra day or two to freshen up?” I frowned. This wasn’t normal protocol, even for back-alley promotions like this. She just laughed at me and slapped my shoulder. “The tournament waits for nobody, Sal. Times a-wasting.” The hallway is dimly lit and the sounds of a ruckus above us are as impossible to ignore as the sounds of thudding, screaming and snapping. As we pass several doors with one-way mirrors on the front panes, I hear sounds I could have never placed in the animal kingdom or otherwise; gurgles, clicks, grunts and even otherworldly whispers. “What the fuck is that? You guys doing animal fights down here? I mean I called a monkey fight once, but it’s not exactly… pleasant.” I shuddered, thinking of the violence chimpanzees can inflict on one another, let alone humans. She never stopped walking or staring directly ahead when she responded.“Those ain’t animals. Not by a long shot.” Before I can probe further, I’m hurried into a changing room and practically swept off my feet by her strength. I turn back and she’s already poking her head out the door. “You’ve got 5 minutes, get your shit and head up the left stairs, Watson will guide you.” She grinned, and I saw gold filings in her teeth that glinted as much as her bedazzled eye patch. “Ya came highly recommended… I expect good things!” I do as instructed and within 5 minutes I’m back in my commentary clothes; an open buttoned Hawaiian shirt with my old Hotel Inertia shirt underneath, skinny black jeans and shimmering black shoes. I found some old slick gorilla powder in my hair and dusted it up, opting for the dishevelled look as I knew I’d be sweating by the end of the ordeal. “You shouldn’t bother putting in so much effort, y’know. They’re not gonna care how good you look, only how well you talk.” Standing in the doorway was a woman in her 40s, dark-skinned and hair clad in meticulous dreadlocks, tied back into a large bun with a pair draped down the sides of her head. She held a thick book in one hand and pocketed a serrated blade in the other before motioning to me. “We’ll have to do the pleasantries on the way, the match is starting and you don’t wanna miss that. The commissioner isn’t the type you want to upset. Especially when you’re not here by choice.” I looked for a moment, dumbfounded. “I’m here because I was invited, already got my pay from the woman who let me in.” I shrugged, pocketing the envelope and getting my equipment from the suitcase. The woman gave a sad smile and shook her head. “Of course you’d think that. She likes it that way. Bet she didn’t introduce herself either, did she? C’mon.” I follow her down and after a few minutes we come to a fork in the hallway, an elevator system to our right and a stairway to the left. Dutifully, Watson stood patiently, still grinning and motioning us to go up. Once we’re situated in our booth upstairs, I set my equipment up and look down at the table, expecting a slew of papers and fighter information in front of me. I look to the woman to ask, but she doesn’t break her stare in the darkness, looking down at the arena floor some 100ft below us.“You won’t need that. Not for this match.” The lights flicker on and the enormity of this venue reveals itself to me. It’s a structure of imposing steel, dried blood, claw marks and other unknown substances that littered the 40ft wide circular pit the fighters contested in, a black lift on either side from the fighters corners that I can only assume ascended up from their locker room area. Around them were chain-link fences that rose up to the audience stands above, situating around 300 people across all four sides. At the very top sat our booth, the commissioner’s office directly opposite, the judges booth to our right and the fight analysts/medical area to our left. Standing in the centre with a spotlight over them was the commissioner, microphone in hand and an energy that was almost palpable. “Ladies, Gentlemen and Freaks of all kinds out there in the universe. I welcome you once more to the annual Nightmare Fighting Championship Tournament! It’s been a long year, but we have new blood to pit against our resident night terrors and some fresh fears to feast on the fortuitous soul that frolics into their den. As always, our contestants will be fighting for their freedom, a chance to get their wish or to fight for the ultimate prize.” The crowd cheers and the majority are hidden behind thick plexiglass and lighting, but I can see some have Karate Gi’s, weapons in hand and others with demon masks as they whoop and holler. The clientele here were, at least in my estimation, experienced. But I was feeling a lump in my throat at that one phrase The Commissioner so surreptitiously added in without issue; “As always, our contestants will befightingfor theirfreedom*”* I leaned to the woman next to me and as if she knew what I was going to ask; she put a finger up and shook her head. Eyes awash with fear and a grimness I had only seen on that of trainers who knew their fighter was not ready for the bout ahead. She pointed the finger down to my machine, then to the pit. Turning it on, I looked down as the commissioner began to talk, readying myself to commentate on whatever weirdos came up to battle. “But before we get to that, we have an exciting exhibition match for our loyal supporters who bankroll this event every year. Without you elite few, we could not do this. You are the pound for pound goats of support! Now, without further ado; let’s get this show on the road!”The rest of the lights clicked on and spun around the venue as they raised the profile of the bout, the elevators both whirring into action as the right one arose first. “In this corner, from the marionettes shop and accompanied by his Bunraku doll “Mr. Stares”, it’s the man who pulls the strings… THE PUPPET MAN!” Out steps a tall, thin Japanese man in full clown makeup. His head shaven save for two ridiculous strands of hair stretched out and fluffed up to their limits, like red antennae. His eyebrows large m’s that practically cover his forehead, the nose a completely vacant slot with a black hole drawn in and the mouth… the fucking mouth was nailed shut. Literally. Sharp rusted nails had been hammered down through the lips with such force that they’d bent. A sickening crimson red face-paint stretched across the entire bottom half of his face, making it seem far larger by comparison. He carefully held a small bundle underneath a sheet and bowed deeply to the audience before standing at his designated spot. “In the other corner, from the streets of god knows where and the womb of someone who misses him… "Hulked Up" Michael O’Donnell!” I watched with wide eyes and a stomach threatening to evacuate its contents at any moment as the smoke cleared and a boy no older than 17 rushed out, beating his chest and screaming to the crowd as if he was the Incredible Hulk. I don’t know if they drugged the poor kid, but he clearly had no idea where he was. “There are no rules, no referees and judges only exist in case of a draw or unclear victory. Our commentary team will take over and we wish you a phenomenal match.” She drools a little before she speaks again, looking up at me and winking. “Let’s make this a violent one.” She snaps her fingers and leaps for the fence, climbing up with ungodly ease before sitting on her makeshift chair in her office. I have no idea what I’m seeing but every cell in my body is urging me to run; I feel my knees tense and my frame rise ever so slightly before the woman next to me puts her hand on my thigh, pushing me down with great force. “You have a job to do, so do I. Trust me, you think you can leave but if you get out of this chair, not only will YOUR life end. Mine will too.” She unsheathes the serrated blade and looks at me with pity. “We both have a part to play here, so put the headset on and let’s do our job, no matter how hard it is.” Hands shaking, I pick up the headset and connect it to the portable recorder and take a breath. “I… I need your name. What is it you do?” I stutter, trying to calm myself. She hands me a bottle of water as the surrounding lights dim and the spotlight focuses on the spectacle below. “I’m Madame Nelle Lockwood, cryptid hunter and your co-host to guide you through tonight. Good to meet you, Sal.” - NFC EXHIBITION MATCH: "Hulked Up" Michael O’Donnell vs The Puppet Man w/ Mr. Stares “Welcome fight fans from around the world, god knows how you’re listening to this or WHY, but here we are. I’m your host Sal “MotorMouth” Sabotta, wishing this was all a bad dream. Joining me this evening is our cryptid specialist and all round badass Madame Nelle Lockwood. How are you doing, Nelle?” She looks at me with a bewildered look on her face before blinking and coming to her senses. “Uhh… good! All things considered… boy, you really have a professional knack for this, huh? I can see why Commissioner Alduin brought you in." “Ahh, yes. That’s right, folks! NFC Commissioner Alduin invited me here personally and our exhibition match proves to be… challenging. Let’s check in on the action below.” I look down and see The Puppet Man sat down and gesturing to the figure under the sheet, like he’s got a negotiation going on. The boy, undeterred and furious, rushes towards him and takes his back, slapping his head and even pulling on his hair with extreme prejudice. “Well take a gander at that, that kid has absolutely NO fear. When I was his age, I would have stayed FAR the fuck away from a nightmare spectre like that. But hell, this is all part of the show, right? Hope they’re paying that poor guy down there a sizeable sum to throw a fight to a child. What do you think, Nelle; is this the weirdest make-a-wish fulfilment task or what?” I look over to her, hoping she’d indulge me and that I could believe this was just going to end with a pissed off actor storming away when the child hit him too hard. But Nelle was scanning her now open book and looking for information on dolls. “He’s talking to his doll because it’s desperate to be let loose. He’s trying to bargain with it to spare him. This is the nature of the puppeteer and his master.” She pushes the book to the centre of the table and shows me a faded illustration of a pristine Bunraku doll; a kind of meticulously crafted Japanese take on the ventriloquist doll. The limbs are thinner and the face is more minimalist, but still no more frightening. “They usually have a symbiotic relationship, but it seems this one obeys the doll and will not want to face more punishment.” “What do you mean more punishment?” I ask, looking back down at the feverish puppet man as he tries signing frantically under the sheet, even putting his head under as the kid bites his arm and kicks him, screeching. “The nails, Sal. Those aren’t to silence him, they’re to punish him.” The rest happened in slow motion; the sheet fell down. The puppet man stood up and walked to his side of the fighters corner, facing the elevator and placing his face into his forearms as he shook. The boy followed to keep attacking, but with one swift kick to the midsection, the boy was propelled back to the centre of the pit where the doll sat. If there was a human face, I didn’t see it. Instead, I was staring down at a small wood carved spider, the head sporting black geisha hair and the makeup still present, but rows of sharpened black teeth protruded from the clicking mouth and two larger eyes jutted out from the base of the skull, smaller ones dotted closely around it. It was like seeing a puppet ogre spider. “Looks like The Puppet Man has let Mr. Stares out to say hi and I can certainly see why he was under that sheet, this one isn’t pretty folks! The face doth fit the name. The question is, what’s he doing to do ne- “I didn’t need to finish the question. My hands shook, and the world spun around me as this creature crawled towards the still wheezing boy with ungodly speed and perched itself expertly beside him. I don’t know if it was my eyes or the distance from where I sat, but this was NOT a small puppet. He was easily half of the boy’s height and that became more unnerving when he reared up on his back legs, the head clicking up and the raspy voice hissing out like a gas leak in a building. “Hey, hey, kid! Wanna make a deal?” The kid rubbed his eyes, seemingly realising where he was as he calmed down and an air of utter confusion around him. “If you let me be your new master and you promise to take care of me, I’ll let you go!” His head spun around and the jaw clicked ferociously as he giggled, extending out a clawed paw. “Whaddya say?” The boy, still confused, slowly reached out his hand and the moment immediately reminded me of a slew of nature shows I’d seen as a kid; where a predator waits until the prey is lulled before striking. I felt the chill up my spine as he extended his hand and grabbed Mr. Stares. In that moment, he leapt up the arm and bore his way into the boy’s mouth, down his throat and shredded his flesh. The sound was so horrifying, so visceral that it outshines any backyard stabbing, joint snap or broken nose. The boy didn’t even have time to scream, he simply looked up with tear-stained eyes as the puppet disappeared. Then he started walking without him realising. He looked down at his limbs, terrified, looked over at The Puppet Master, who still had his head to the elevator and pleaded with someone, anyone to help him. I looked to Nelle who refused to take her eyes away, studying the battle in an almost morbid scientific curiosity, detached entirely from the scenario. I couldn’t fathom how she did it, how she ignored this boy begging us to get him out of there. I wanted to. Every instinct in me as a fight fan and a decent human was to scream “STOP THE FIGHT!”. But clearly, when my own life is at risk and money is involved... I am not a decent human. Instead, with bile in my throat and a sweating forehead, I did my job. “M-My goodness! The P-uppet, I mean, “Mr. Stares” has BECAME the puppet master, surely the fight will be over with our young competitor incapacitated? What does our commissioner have to say about this?” She stared at me, her one eye gleaming and her face elated with the violence. “It ain’t over yet, church boy. We haven’t even seen the finale, have we Puppet Master?!” She laughs and slaps her knee, the puppet master sobbing as he sinks to the floor and she continues. “He ain’t done feeding, not yet.” The way she said that word “feeding” nearly made me lose what food I had in me. That was a young man, somebody's baby boy… “What does she mean by that, Nelle? What is the strategy to victory here?” Nelle looked down at her book and traced her finger across a passage before wiping her forehead and pushing the locks aside. If her composure wasn’t breaking yet, it would do soon. “This kind of parasitic doll feasts on its prey and targets non-essential organs first, controls the host with the neurotoxin in its tail and then, when it’s finally content, it gives the brain a second injection.” “What happens then?” I asked, my own professionalism hanging on by a fucking thread at this point. She shook her head and pinched the bridge of her nose.“I guess you’ll see in a moment, I sure as hell don’t want to. Not again.” Before I can prompt her further, the boy lets out an ear-piercing shriek and falls to his knees, gripping at his head before it turned red, then purple and finally an ugly shade of puce before… The sound of a watermelon hitting the ground from a great height is the best comparison you’re going to get without making me want to rush to the toilet to puke for a third time. But that’s what happened. His head burst and chunks of his skull, flesh and brain matter sprayed the pit and the walls, some hitting my desk and making me audibly shriek, much to the commissioner's delight. “HA! You didn’t run! I like you, Sal. You pass for the tournament!” She hauls her body up and slams down to the pit, applauding as the microphone descends from the heavens. “And your winner; The Puppet Man and Mr. Stares!” The crowd erupts with applause as the weeping puppet man pulls the blood-soaked puppet out, places him under the sheet and silently begins to walk back to the elevator while attendees clear up the boy’s corpse. “What… what the fuck IS this place?” I ask Nelle, pausing my recording. “This is where nightmares are kept and set upon mostly unwilling competitors for the world’s amusement. You HAVE done dark web fights before, right? Mafia snitches being put into lions pits, bum fights, addicts fighting women to score… this can’t be THAT unusual to you?” I stared at her incredulously. Was that even a question? “I did the dark web ONCE and it damn sure didn’t involve monsters!” She scoffs and closes her book, stretching before looking at me with contempt. “Oh, it did. Just not the ones you hear about in fairytales. Good luck with the selection process. I’ll be back for the opening round. Don’t try to run, they’ll devour us both in minutes, if you think this is the pinnacle of what lurks beneath this club, you're in for a rough night.” She sauntered off, leaving me deflated, sickened and terrified. Unable to leave and frustrated to the point of tears that I couldn’t express that concoction of emotions, I did what I always do; I regressed and pressed “record” on the device as Commissioner Alduin continued. At that moment, however, I was deaf to it all. The gravity of the situation had fully enveloped me… They weren’t kidding about the unwilling participants, I just didn’t realise I would be one of them.On every side of me sits men and women with a desire for violence that goes beyond the norm, beyond the sane and beyond the boundaries of humanity.Below me are an untold number of creatures rattling their cages and howling for blood. Across from me is a woman so powerful she could crush my skull beneath her boot with the utmost ease if it so amused her. That invitation was nothing more than my own ransom note in pretty colours and flattering platitudes. I was in a tournament housing nightmares incarnate. And it would only get more violent from here on out. - The opening round was a blood bath.
I have only tested with a Raspberry Pi 4 B. (Mine has 4 GiB of RAM.) A Raspberry Pi 3 B/B+ would probably work (as the Pi 3 is 64-bit, though it has less RAM), but has not been tested. If you test on a Pi 3, please report your results (good or bad).
While the HOWTO includes the usual steps for encryption (both native and LUKS), I have not tested them (yet?). I have only tested an unencrypted install. If you test encryption, please report your results (good or bad).
While this uses a dataset layout that matches the regular HOWTO / the Ubuntu installer, zsys is not supported as the Raspberry Pi does not use GRUB.
Onion Monero Blockchain Explorer by mWo12 included.
Auto loading menu for Monero updates, and script that auto detects, formats and mounts attached USB drives. Labels drive for simple detection by future versions of PiNode-XMR so the blockchain is maintained between versions.
tor bridging Node - routes your transactions through the tor network
Public Node - Using new RPC payment feature* - soon
Private Node - with mining (For education/experiment only)
Simple control with Web-UI
View Monero node and hardware status
Control bandwidth, connection limits and RPC port
Transaction pool and summary viewer
View connected peer info
Monerod log file view page
Easy setup menu for config of passwords, USB storage, Update and optional dynamic DNS.
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.

You'll need to then manually expand that partition to the size of the drive, but may be useful to know.
My career isn’t always dangerous, but clients can be unpredictable
My name is Amy, and I’m what’s called a Computer Dominatrix. My clients are all long distance, we never interact face-to-face, and I have control over all of them. Some give me absolute control, some give me specific portions with boundaries. Some are married or dating, others are single. They all make use of my talents to give up control of at least part of their lives. When a new client contacts me, we exchange a few messages so I have some background about them, and I lay out what my services usually entail. I tell a few stories of what other clients have asked me to do for them, to help the new client select scenarios they would like to set up. Most of my clients have never had a Digital Dom before. So, giving them a few examples and options helps bolster their confidence. The usual set-up goes like this: my client installs some spyware on their computer that I control. It gives me the power to do things like lock their computer, see their screen, disable the keyboard, take over control of their computer, and get reports of what they’re doing on their computer. With this tool, I can perform my services. Some clients want me to watch their bank statements and shame them if they spend too much money or buy surprise things with their money as if I own the account. Other clients want me to monitor their porn usage and shame them for what they look up. Or, if I log in and catch them using porn, I should direct them to different porn of my choosing and force them to watch that instead. One even wanted me to try and break into his computer and install the spyware secretly. That was a fun client to work with. When it comes down to it, they just want to relinquish a little control over their lives. I understand where their desires come from, and knowing it helps me be a better Dom. Contrasting the fun times of my career, I’ve had a few mishaps and horrible things happen. I had one client sign up for my services. We messaged a few times to get to know one another before I agreed to accept him as a client. He was in his mid thirties, single, and wanted me to watch him look at porn and make random comments on the things he was watching. Really, not that abnormal for my choice of career. I had him sign an agreement that helps me avoid legal trouble if they try to report me for hacking (had this happen before), and we got started. I gave him the url where he could install my personal spyware, and he followed through. He only asked that I give him a little advance notice before I start watching, which I agreed to. Boundaries are important. I would check up on him twice a week, and send him a message before I did saying “I’m coming to check on you in ten minutes, you better be watching something good.” I would log in ten minutes later to the second and start either shaming him for his choice of videos or praise him for making the “right” choice. All of this was predetermined. Things were going fine with this client, and I balanced him with about 10 others. Being a Digital Dom makes it easy to spread your attention across many clients. Bonus if you can get clients from different time zones so they would log in at different times so you don’t have to multitask. I was about to check in with another client, when I mis-clicked in my software. See, my spyware (which I paid to be custom written after wishing for more features in commercial tools) lists my clients by most recently connected in one screen. When I add a new client, it can mess with the order of the page I am so used to mindlessly clicking through. I’ve since paid for that to get fixed and sort clients alphabetically, but this time I made a mistake. I clicked on this new client and connected to his computer. A gasp escaped my lips as I saw what he was looking at. I’ll leave that up to your imagination. It was some of the most fucked up porn I’ve ever seen. Involving victims of questionable age. And blood. If I could have slipped out of there, I would have. But this client requested a popup to appear whenever I connected so he would know I was there. That popup revealed my unexpected presence. Instead of panicking and trying to close the window, he calmly moved his mouse to the task bar and opened a text document. I was frozen while watching him type. I should have logged straight out, but I instead started to open a voice channel to tell him I was dropping him as a client. It was too much for me, and I decided to set that boundary early on in my career.
“Like what you see?”
He had typed into the word document, and the cursor blinked impatiently at me. I thought my voice would crack, so I took over the keyboard and typed back.
“I’m sorry, but I’m going to refund your money and no longer service you. Please uninstall this software and watch for your refund.”
He paused for a while, and I waited for him to respond once before I disconnected. He took too long, so I closed the window and took a deep breath while sitting back. I was feeling really disconcerted from what I’d watched. It wasn’t the first time a client had tried to show me illegal things during a session, but it always makes me sick when they do. I gave the reins over to another Digital Dom I have partnered with. We take over for each other if we feel ill or something. Just temporarily. I went to take a shower to wash out those images.
My computer started acting up more than a month later. So much had gone on since dropping that client that I didn’t connect the two at first. The computer would slow down for a few minutes, then resume its normal speed. I assumed it was because I hadn’t restarted in a while, so I restarted it. That seemed to fix the problem. When I had rebooted, the wifi slowed down considerably, enough for my roommate, Jess, to ask if I was downloading anything big. I had logged into the router to see if that also needed to be restarted when I noticed a device I didn’t recognize was connected to the wifi. I swallowed hard. RASPI was the name of the connected device. It had connected to the network three days ago. Some strangers' device was on our network. And they had to be nearby, at least within range of wifi. I immediately suspected that a neighbor had brute forced our wifi password and was now stealing internet. Before kicking the device off, I looked at the router’s traffic report. The device had a significant size of traffic in the last few days, but my computer used the most out of all of our devices. The device came in 5th place for most data used. It made sense that my computer was using so much bandwidth, but 75+ gigabytes in 3 days was excessive. My throat seized, and I immediately reached around to the back of my computer and unplugged the ethernet cable. Deep, primal panic set in. This was a very specific attack. It’s not the kind of hacking you can do en masse to install some ransomware or adware. Someone was targeting me or both of us. Someone who was willing to spend time brute forcing a wifi password and going after one specific machine on the network.
I called Lucas, the guy I hired to write my spyware for me, and filled him in on everything I knew. He knows perfectly well what his software is used for and isn’t weird about it. He agreed to take a look at my computer for a fee. So, trusting him as I have all my career, I installed a commercial remote desktop tool and let him connect. The moment I reconnected the computer to the internet, the router showed a spike in traffic again. I had him on a call while he worked, and I watched what he did carefully, trying my best to learn what he was doing so I could troubleshoot myself if this ever happened again. “Oh shit,” Lucas muttered. He had a traffic analyzer and computer process analyzer open on-screen. “Amy, I think you got hacked. Like, they’re downloading your hard drive!” “They’re what?!” I began to really panic. I had a lot of my clients information on this machine. Keys that let me log into their machines. Bitcoin Cash addresses and keys where I stored my fees. Now someone had them. They could easily start stealing and spending my thousands in accumulated fees and harass my clients. I’d lose a big chunk of my savings and my livelihood. Immediately, I took over the computer and shut Lucas out while I created new crypto addresses and started transferring money. The fees from transferring would make me lose a little money, but it was better than losing it all. I also started backing up the hard drive to several USB drives I had lying around. Just the important stuff like my files, personal photos, and client info. When I let Lucas back in, he got to work finding the process that was exfiltrating my data and shutting it down. He tracked down the executable that was running the show and downloaded it to his own computer before deleting it from mine. He promised to dissect it as best he could to figure out what it was doing. Before he did that, however, he started monitoring my system to make sure the virus had been truly cleared out. While watching my system, he gave me a task. “Walk around your apartment. Search everywhere and look for that rogue device. It’s been continuously connected for days, which means whoever is doing this is probably not camped out on the road. From the name, I’d guess it’s a Raspberry Pi -- a small computer about the size of a phone but two inches tall.” He sent me a picture of the type of device we were looking for. “They probably left it hidden somewhere, either connected to an outlet or with a large battery pack. Go and look for it,” he insisted. I got Jess to help me search the place top to bottom. Nothing. Not even outside in the bushes or on the back porch. We split up and went to our neighbors, asking if they’d seen anyone suspicious hanging around the building in the last week. No one on our floor had. I went upstairs and asked the same questions. Our upstairs neighbor said the only person he’d seen was a guy coming to update their satellite dish on the balcony. My throat seized up as I realized that could be them. I asked hesitantly if I could look at their dish. I didn’t know them, but briefly explained that someone had left a device lying around that was breaking into our wifi and that our next step was to call the police. They panicked at that, and let me check their balcony if I promised to keep them out of it if I called the cops. I agreed, knowing full well that they did drugs and would hate for the police to come around the apartment complex. There, on the balcony, was exactly what Lucas had told me to look for. A black box sat along the wall between the satellite and the wall the cable ran into. A power cord exited the box and connected to an outlet on the balcony. I cracked open the box with my fingers and found a circuit board inside, connected via usb to the outlet. The satellite cable passed straight through the box without connecting to anything. The box was a fake, made to look like it was doing something to the cable as it passed through. The circuit board looked exactly like the picture Lucas had shown me. There was our rogue device. I unplugged the device, fully aware that unplugging it would alert whoever was controlling it. They could assume it was disconnected accidentally, or they would think I had found it. Either way, I couldn’t just leave it. I thanked the neighbors and left with the whole box. Jess met me on the stairs, saying that Lucas had asked her to disconnect the internet on the computer and have me call him back. Jess stared in wide-eyed shock as I showed her what I’d found. The upstairs neighbors were well within range of our wifi for the device to connect. The job was only barely sloppy enough to detect. We were lucky I had found it at all.
On the phone Lucas sounded panicked. “They didn’t just copy your hard drive, they added files to it,” he squeaked. “Bad files. Bad pictures.” My jaw tightened, and I felt sick. I made the connection to the client I’d dropped. “Delete all your shit now,” Lucas was demanding. “You already backed up what you want, you need to destroy that hard drive. Smash it, burn it, bury it. Go get a new hard drive. Start as fresh as you can. I can help you get set back up if you want.” “I think I know what’ll happen,” I muttered. “He’ll call the police on me and tip them off that I have those… pictures. They’ll find it and arrest me for possession. Game over.” “He? You know who it is?” Lucas pressed. I told him about the client I’d dropped. “That’s why you need to torch your hard drives. Now. Both of you. Same with your phones. Who knows where else he’s been,” was Lucas’ advice. I won’t confirm or deny what I did with the hard drive or the device. If I destroyed it, it would technically be destruction of evidence. I ordered a new hard drive and reinstalled everything. I explained to my clients that I had lost internet connection for a couple of days, and didn’t end up losing any clients. I haven’t told the police everything. The last time I got involved with them, there was so much harassment from them about my career that I’d rather not have more negative interactions with them. It just isn’t worth it in this case. I kept my report short and simple: a guy I met online and dumped might try something and come to my house. I gave them the information the client gave me, but I suspect more and more that it was fake. Making a report will help if anything new happens. I’ve written about this before on other anonymous forums, specifically for other Doms. Because of those posts, a few journalists have reached out and are writing features based on me, my career, and these events. They should be published in the next few days. I’m just interested in sharing stories like this as publicly as possible, for awareness. Lucas explained that the Raspberry Pi was a tiny computer that had a cellular connection so the client could connect to it from anywhere in the world and try to break into my wifi. Once he had succeeded, the client had gone to work breaking into my computer and getting their malware installed. We still don’t know 100% how he did it. Lucas worked tirelessly to revise his software and remove vulnerabilities that could be used to trace me. We don’t know which vulnerabilities the client used, if any. We do know that there is one left, however. I know this because every once in a while, a client will show up in my software who I didn’t sign up. A new name and data every time. I don’t dare click it. I just know what will be waiting for me upon connection.
“Like what you see?”
Lucas hasn’t been able to track down how he’s injecting fake clients into the software. Until Lucas can fix it, all I can do is click carefully and not connect again by accident. I’m sure the client is using a modified version of my spyware, ready to do all kinds of damage the moment I connect. The guy is clearly an expert. Who knows how many other people he’s done something like this to. One thing is certain: he was prepared to conduct this attack. My career isn’t always dangerous, but the clients can be unpredictable.
Hello everybody, Long time holder first time poster. I just set up a Full node with LN node on a Pi 4. Following this guide [https://stadicus.github.io/RaspiBolt/] super easy, barely an inconvenience. Anyway, I'm not going to sugarcoat it I'm a noob and I'm hoping for some help. First can you guys point me to any resources that break it down crayon Barney style for the slower LN bitcoin user? Second if I can ask a few questions in this post:
I deposited 89398 sats to my LN node. my total balance is 34708 sats. With the difference being tied up in the channel. Do you recover those funds if the channel is closed? Can you open more channels? How do I make my node fee less? Does the node just take a percentage of the deposited coins to open channels?
Bitcoin Node Questions
Does the node require upkeep? It helps the network to just run a node correct? Thank you for taking the time to read this and answer any questions you can. Like I said I've been a holder but the longer this goes on and the more money the government just randomly prints I'm seeing this as way more than just an investment. I see it as the future so I'm trying to learn as much as I can now. https://preview.redd.it/12pbi7zs8u831.jpg?width=3012&format=pjpg&auto=webp&s=2ac1585bca24706bc79bd7ac1f94a062d75909f0 Respectfully, noob Edit: 7JUY19 Firstly, I wanted to thank everyone for all the information. The bitcoin community is pretty amazing. Secondly, do I need to give any one an address to my LND node or can people just use it? I noticed in one of the comments someone posted an address and said feel free to use it. I want everyone to be able to use mine if they need it. Pubkey 03c4485a19af0a3226b9d60c2af7ddb9789c0baa3107abf24b14211967ef1cb395 https://preview.redd.it/78f70rs7dy831.png?width=265&format=png&auto=webp&s=4cf78dbb6fb1c31f5736398e7fbbe7c9a186494e Edit 2: Running a node behind TOR has any one had issues. I set it up but I could not see my node so I reverted back.
Hi guys, I have looked at mining many times and never got my head around it properly. Can anyone point me in the right direction of mining economically/profitably? I currently have 60GH/s on zenminer, but that isn't returning hardly anything. Any advice greatly appreciated.
Bitcoin node/Lightning nodes with 1tb storage capacity
Long question incoming, hopefully I can ask this clearly... I'll start with some background info that leads to my question... I have done some research, and I am finding conflicting information, so I am hoping someone here can give insight... manydifferentsources put the current bitcoin node count at around 10,000. Othersources claim the count is closer to 100,000... For the Lightning network, 1ML shows that there are currently nearly 10,000 lightning nodes... the blockchain continues to grow as more blocks are mined, so more storage is always needed to run a full node. From my rough calculations, it seems that the blockchain is currently growing at a rate of ~45gb/yr. Source. The gb/yr growth rate seems to be increasing quite a bit year to year... so, my question... When will the blockchain surpass 1tb, and what happens to network security/all of the nodes using 1tb storage once the blockchain surpasses 1tb in size? Is the 1tb blockchain size milestone something to be concerned about?... I could be wrong, but I assume that many nodes, especially Lightning nodes, are using 1tb storage (assumption based on the popularity of Raspibolt, Raspiblitz, and Casa Node which all have 1tb storage.) The main chain might not be impacted (hard to say based on the conflicting node count information), but won't this lead to many LN nodes going down/channels being closed? Just something I've been curious about, I'd appreciate any thoughts on this question.
[Showerthought] Bitcoin is a "User Activated Soft Fork" of the current financial system - A user driven change to the consensus rules that does not invalidate the old rules.
In 2012 (the good, old) Jeff Garzik replied to a question on whether it's possible to "force" a change (to SHA-512) on the network without having the hash power "to back it". He replied
There is no "force", there is choice. Each user chooses the software they run to validate the chain. If a majority of users choose to switch to SHA-512, that is what will happen, regardless of the number of miners who switch. 51% hashing power, or even 90%, means nothing if clients collectively refuse to accept and relay your blocks. -- Jeff Garzik, July 14, 2012
Bitcoin is the same. It doesn't matter how many institutions "support it", or "back it", or "adopt it". What matters is user choice - If users collectively stop accepting fiat for their work, that is what will happen, Bitcoin will prevail. (But it won't invalidate fiat, hence a soft fork.) Just like $billions in mining power have to bow to a swarm of RasPi's enforcing SegWit, so all the central banks and governments of the world will have to bow to people using Bitcoin.
Hello All, I have been trying to get into bitcoin or any form of cryptocurrency for a while now. I have a raspi 2 B that I would love to start mining with as a hobby. More of a learning experience. I know theres not much profit to be made right now with mining unless you have some form of free electricity and even then I'm sure its not much of a profit. Anyways, I have no idea where to even start. Everything about setting it up is sort of confusing. I would greatly appreciate any sort of documentation to help me along. Thanks!
Correct me if i'm wrong , but in the bitcoin there's mining and validating ? If I understand correctly the validating part is done by full node ? This full node is just a bitcoind running on a basic computer (old pc , raspi etc ....) There's a lot of talk about bitcoin network capacity and the validation time , correct ?? (even without trolling about BU and core) . We can all agree the faster the validation, the better it is ?? My question is : supposing i'm running a full node , could it be possible to plug on the node , old mining hardware like USB key to help the computation . Doing so increasing validation speed ?
[uncensored-r/Bitcoin] You think you've seen Raspberry Pi's running BTC? Think again ;)
The following post by F4T4LGodsend is being replicated because some comments within the post(but not the post itself) have been silently removed. The original post can be found(in censored form) at this link: np.reddit.com/ Bitcoin/comments/81fkpt The original post's content was as follows:
Hey yall, since posting raspi setups has become popular on here, I thought I would share my Crypto Cluster. https://imgur.com/a/SJ89Q PI1 - Running Bitcoind 0.16.0 as a full node and CLightning. CLightning running on testnet PI2 - Running BTCD Roasbeef Fork and LND. LND running on mainnet connecting to external full node via RPC. PI3 - Running full nodes for other related currencies PI4 - Running CGMiner with old ass Gridseed miner lottery mining scrypt Two 1tb external hard drives connected to PI1 and PI3 to store full blockchain for BTC and Other.
Are they fast? No.
Could I have just flashed an old laptop with Ubuntu and hooked up an external? Yes.
Was it worth the money? Worth it to me.
Do I recommend running nodes and lightning software on Raspi's? Meh, only if you are looking for a good time ;)
Once in Raspi-config there are a few steps. You'll need to 1) expand the file system, 2) enable SSH, 3) auto boot to desktop and 4) change the internationalisation options. I left the account as pi for mine since this will only be a local device with no outside access. However, most places recommend you change the account/password from default for security reasons.
OPTIONAL: I found for the monitor I used, I had to enable overscan in order for the image to fill the screen.
STRONGLY ENCOURAGED: It's probably best to set a static IP address for the Pi. You have two options to do this. You can either set a dhcp reservation on the router or modify the /etc/network/interfaces file on the Pi itself. In ther interfaces file, you'll need to modify the line that says:
iface eth0 inet dhcp
to something like the below (with the data filled out). A good set of instructions are here:
You will need a program called unclutter to remove the mouse cursor during the display
sudo apt-get install unclutter
At this point, you will want to disable the screen saver. Head to /etc/xdg/lxsession/LXDE-pi/autostart and you'll want to comment out (add a #) to the line that says
and you'll want to add these lines to the bottom of the file
@xset s off @xset -dpms @xset s noblank @sed -i 's/"exited_cleanly": false/"exited_cleanly": true/' ~/.config/chromium-browseDefault/Preferences
OPTIONAL: I decided to have my Pi turn on/off the hdmi on a regular schedule (I don't need the dashboard during the night hours). Follow this guide to create the files. He has the path to where the files are to be saved at the top of each file. Modify the /etc/cron.d/raspi-monitor-scheduler to your preferences. I have mine turn on at 6am, off at 8:30am, on at 5pm, and off at 11pm during the weekdays.
Create a folder in your home pi directory for the html files for your dashboard.
sudo mkdir /home/pi/html/
Finally create a new desktop file to tell the Pi to automatically load Chromium upon boot:
IMPORTANT: I pointed Chromium to load a file that I called Dashboard.html. It's your call on what you want to name the file, but make sure you point it to the right one.
Step 2: Set up the HTML File to Display
This is entirely your choice to what you want to display (and how). I included a calendar, news widget, stock ticker, to do list, traffic, and weather. There are a lot of ways to do this, and I'd even encourage borrowing from the magic mirror project. But, I'll provide links for my approach.
I built it as a main page (Dashboard.html) with the page elements being pulled through via iframes. I found it easier to align and space things this way since I was combining so many different elements.
I only added a few elements in the html heading to add a background image (vs. white) and to have the webpage "auto-refresh". Since I am only interacting via ssh, it was easier than writing a script to hit f5 or leaving the page completely static.
My Folder structure looks like
Background.png - I used this as my background. I just searched for something that I liked that is 1920 x 1080.
News - I used Feed Grabbr for my news feed. Their service is free if you have 1 widget with <3 RSS feeds. My minor gripes is that they only refresh every 9h for the free service (which, frankly, is totally fair) and its only one format unless you pay (again, totally fair).
Map - I used Google Maps to show a local map with traffic. The most difficult process here is that you need to create an API key to pull the data. As long as you have 25k requests/day or less, the service is free.
Stocks - I used Trading View for coming up with a stock widget. I used a single tab with a few stocks that I follow (+ the VIX, S&P 500, and the 10yr Treasury). It seems to have a fairly comprehensive reach of data (from FRED, to bitcoin, to futures/forex). I personally ignored the chart since I won't be interacting with the board.
To Do - I used FeedWind to come up with a short RSS widget that pulls in my to do list from Remember the Milk. I decided on this one since it was free and fairly customizable.
Weather - I decided to use Forecast.io for a weather widget.
Calendar - I used this link for a google calendar embed. Personally, I took off everything but the time zone in the headings. I really don't like the "baby blue" and am looking at replacing this one next.
To wrap it up, my html code looks like the below. I fiddled with the sizing, but I'm sure someone can come up with a more elegant solution.
top section bottom section - -
FINAL Comments. This project probably took me 1h to set up the pi. And 4ish hours stumbling around to get the dashboard set up. My only real outlay was a monitor mount and a new monitor. Best of luck! EDIT Here is the link for the current version of the dashboard. I removed the traffic for the weekend, but this is the dashboard. I have some formatting I really want to do (headings et al), but this should be a decent start. I have also included the color scheme I used.
Rebuttal to Roger Ver's points made on Mad Bitcoins interview (And partial transcript)
Here are some of the items Roger said that I found interesting and/or worthy of debate and also some quick responses. All in all I think this was a much better presentation of his argument (though still flawed IMO). I took the time to transcribe some of his statements (There may be errors, memorydealers I would be happy to correct anything I quoted that is wrong) I left my responses purposefully brief. I am hoping others can add details or extend them to further prove or disprove any statement (including stuff I wrote that's wrong or that you disagree with). I am hoping that someone from core goes on with Mad Bitcoins tomorrow night. https://www.youtube.com/watch?v=XpOnolf1tS8
@3:00 "So anybody that thinks that high fees, and slow confirmations and full blocks are a good thing for bitcoin, they are plain and simple wrong and they don't understand the things that make bitcoin useful as money."
Just because people don't agree with you doesn't make them wrong. Its simply different priorities.
IMO the thing that makes bitcoin useful is not only that it is money, it is that it is decentralized money. Anything that puts decentralization at risk will cause the value to decline at least as much things that make it less useful as money.
@3:14 "And people talk about, well bitcoin is a store of value. Well the only reason people want to save money is so they can spend it later and if bitcoin becomes not usable as a means of exchange so people won't want to save their wealth in it either...If bitcoin can't be used a medium of exchange, it won't be used as a store of value"
Bad argument since it can be used as a medium of exchange
Bad argument because people use gold as a store of value and it is not a very good medium of exchange
@6:30 "Either they can mine an empty block during that time period while the block is being propagated and validated or they don't mine at all so as a miner its very very clear it would be better to mine an empty block and get the 12.5 coins from that than to not mine at all during that period and have no chance of getting a block..."
bigger blocks would create more empty blocks
[continued] "...Its actually a nice way of slowing the network down from getting ahead of itself, if the blocks are too big and they are propagating around and its taking too long for people to get a whole copy of them the fact that a pool is mining an empty block, it lets rest of the network catch back up because the empty block propagates very quickly and it can be validated very quickly so it lets the whole bitcoin network catch back up to where things are supposed to be. So its actually kind of a nice safety valve for slowing the down the speed of the transaction rate on the bitcoin network if needed."
Interesting to hear the argument for small blocks inserted here
"@8:30 So right now the block size is set by a couple dozen core dev who decided who have decided the maximum size is 1MB"
Blocksize was set by satoshi
Code is open source and it is trivial to change the blocksize
@9:30 "Also, all the mining pool operators are running nodes as well and those are the ones that actually secure the network and validate the blocks and do that"
miners are not the ones who validate blocks except in the capacity that they don't want them to be rejected by the true validators: the users
@9:47 "That's probably why this whole debate hasn't been settled already because there is not any one specific place you can point too and say this is who is in charge of solving this issue."
Interesting reference to centralization
@10:40 "as were seeing from this current scaling debate there is this huge huge huge motivation for everybody to stay on the same chain and be part of the same bitcoin network, so even once the users are able to configure this themselves, I think 99% are still gonna stay on the same chain"
So basically emergent consensus wont actually do anything because they know >1MB is still contentious and they want to stay with the 99%
non-contentious forking is really just an exercise in mass coordination, this has been a hot dev topic for many years
@12:55 "The developers at bu come up with an amazing technology called extreme thin blocks"
The one that had a bug in it for over a year that could be exploited to crash a node remotely
@15:20 "I think bitcoin mining is more decentralized than ever"
It is almost impossible to gauge this
I would argue that the opposite is true, but I would need to do more research
@18:02 "The things segwit solves/the issues it addresses aren't things that need to be fixed urgently"
BU doesn't raise blocksize limit right away unless users want a contentious split, which they probably don't (Roger mentioned earlier that users have a huge motivation to stay on the same chain)
@20:02 "If you're hard forking for a good reason, it's not contentious"
This is an example of centralization: "Only my ideas could be considered a good reason"
@20:58 "Lets say it somehow splits at 50/50 .... blocks will take 20 minutes to confirm. The transaction capacity will be half."
He is describing how the 1MB chain will die after a split.
Seems to me those who value bitcoin centralization will be just fine waiting for 20 minutes or longer, especially since segwit activation will jump to 60%+
@23:14 "And if you have an opinion like i do on this as to which version of bitcoin is the better one. I will sell my coins on the slow expensive core chain...bitcoin unlimited coins will be so much more useful because you actually be able to send and receive them with people unlike the bitcoin core coins on this congested network that cost a fortune and take for ever to move the bitcoins"
A threat to dump bitcoins. I will buy some.
@30:52 "And the miners, the majority if their income is from the block reward and not from the fees on the network and the will continue to be the case for like the next 100 years."
In 2040 (assuming 4 year reward halvings) the reward will drop to 0.19531250 BTC
@31:02 "And its worth pointing out that the bitcoin unlimited guys they are not opposed to layer 2 technologies at all, we're excited about layer 2 tech...but our point is don't strangle bitcoins layer that brought us from nothing to where are today"
I just thought it was interesting the use of the word "we're" here
@32:12 "Whereas a lot of the core developers today are actively saying that they want to damage the bitcoin that brought to where we are today"
This is a very repeated point and in someways, seems like the only point. Probably a good place to focus for anyone engaging in debate
Nobody is saying this, this is putting words in people's moths just because they disagree with methodology and priorities.
@33:16 "People that are part of bitcoin core are part of bitcoin core are openly and intentionally advocating for high fees and full blocks, thats kryptonite for bitcoin"
OK Im drunk now because I took a shot every time roger made this point.
Again, putting words and intentions in people's month, disagreeing with someone's method of improvement of a thing is not an argument that someone is trying to harm that thing.
@38:12 "So for me I think its time to switch to BU, A dev team that understands why bitcoin is useful as money"
Personally I don't want to trust anyone one team
@40:23 "the bitcoin core camp seem to think that bitcoin will only be used as a store of value, so they are undermining its usefulness in commerce"
@44:40 [Regarding BU Bug Fix removed from /bitcoin] "I think everyone involved with bitcoin should condemn that sort of activity"
I agree with Roger here, alternative Bitcoin implementations should never be considered an altcoin, alternative consensus proposals should always be heard
@49:06 Right now you can run bitcoin on a raspi for $25
Cost of computing is not the main concern, storage is an issue, but the main concern is network costs
@49:12 "My understanding of their side is...I guess they have 2 [concerns]...One concern they have is that they think that bitcoin network is going to become centralized."
This point can not be overstated, though it seems glossed over when considering what is best for bitcoin
never got to 2nd item because he got too busy going back to his repetitive defense
(paraphrased) Bigger blocks = more people = more decentralization
More rich people
IMO raw growth is not always the best answer, especially scaling can be gained through optimizations
"As soon as the user experiences started to decline (slow confirmation, high fees), adoption has started to decline"
This doesn't seem true, would be worth investigating
@51:50 "bu will have bitcoin.com"
when asked if BU should just take on a new name
another example of new centralization, I don't have a problem with bitcoin.com per se, it's just that some of the arguments against core revolve around centralization concerns
earlier he says "bitcoin core, good marketing" (referring to choosing the name)
Here are a few I've come across trying to do something different with my pi. You wouldn't normally have these installed on your raspberry pi but a few that have piqued my interest because of specific things I wanted my pi to do.
When Bitcoin first took off, the concept of mining currency on your computer was pretty foreign to most of us. The idea is that your computer verifies transactions, and in turn you’re rewarded with some currency. How many transactions you can verify is directly correctly to how powerful your computer is. Bitcoin is a cryptocurrency, a form of electronic cash.It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user via the bitcoin network.. There are two main methods for obtaining bitcoin: mining and purchasing. In this tutorial we will focus on cryptocurrency mining on the Raspberry Pi! ... Bitcoin Mining mit dem Raspberry Pi zahlt sich nicht mehr aus. Die Entwicklungsgeschichte fand damals nicht ihr Ende. Immer weiter ging es mit den Optimierungen, der Steigerung der Hashrate bei gleichzeitiger Senkung des Stromverbrauchs voran. Die Gesamthashleistung des Bitcoinnetzwerkes kratzt gerade an den 80 Exahashes und stellt neue Rekorde auf. Heutzutage lohnt sich das Minen von Bitcoins ... Das Besondere am Raspberry Pi 3 und gerade auch im Bezug auf das Bitcoin-Mining, ist der niedrige Stromverbrauch. Das Raspberry Pi benötig gerade einmal 4 Watt; moderne Desktop-Computer und Laptops hingegen benötigen ein Vielfaches von ~700 Watt. Um die Mining-Geschwindigkeit zu erhöhen, können mehrere Raspberry 2 Computer zusammengeschlossen werden oder speziell für das Mining ... Einkünfte aus Bitcoin-Mining können steuerpflichtig sein Das Bundesfinanzministerium hat sich ins Neuland gewagt und auf Anfrage von heise online erste Auskünfte gegeben: Auf alle, die die ...
