Dumb comment. We have people paying for beers and coffee every single day. Lightning works. Your criticisms were deprecated about 5 years ago. Update your OS.

https://github.com/LedgerHQ/ledger-secure-os/tree/main > Only a few pieces of the OS are available as of today, but more will come in the future. Without the entire thing public. It isn't open sourced. What I meant prior is there is nothing saying the seed doesn't automatically get sent to their system without seeing the full source code. This what they are doing is called open core. Not open source. Like another name is partial open source. But it isn't open source since open source requires everything to be public. https://www.techtarget.com/searchitoperations/definition/open-core-model-open-core-software One of the most widely recognized and influential definitions of open Source software is the Open Source Definition, published by the Open Source Initiative (0SI). The is a non-profit organization that promotes and protects the open source movement. The has a list of licenses that have been approved as conforming to the Open Source Definition, and grants a certification mark to software that uses one of these licenses. The Open Source Definition has 10 criteria that open Source software must comply with, such as free redistribution, source code availability, derived works, no discrimination, and no restriction on other software According to the OSI, open core software is not considered open source software, because it violates the Open Source Definition. Specifically, open core software does not allow derived works and modifications to be distributed under the same terms as the original software, and it restricts other software that is distributed along with the licensed software. The argues that open core software is a marketing strategy that exploits the goodwill and reputation of the open source movement, while undermining its values and principles.

I'm not sure if every actor creates a blockchain. Actors will more likely use existing and well established chains. It's like MS Windows. Not every company is using an own system in their computers, they use Windows. Or take Android. Not every smartphone producing company is creating an OS. Salesforce, SAP are selling products. A construction company is not developing an excavator. They buy a Cat or komatsu. See what I mean? Ethereum, Solana or Cosmos sell infrastructure. Not everything can be rebuild in the same quality by every actor. They use Well established products.

hey bud, there's no misrepresentation here. These are your exact words which I'm taking exception with: > only use Linux OS for any serious Bitcoin computing. At no point have I threatened you. I didn't propose that anybody invest time and effort into learning anything, so that's a strawman. You gave a blanket admonition to never use any OS but Linux for serious Bitcoin computing. I think that's poor advice and I suggested a couple of alternatives. The bluster is all you, buddy; you're trying to make this a convo about many things which are unrelated to my comment. I recognize I was insensitive with my wording and that probably put you on the defensive. Sorry for being a bit of a jerk about it, but I think my position is still the correct one. To recap, my position is "people should use an OS they are familiar with comfortable securing, and if they want to learn a unixlike, there are plenty of alternatives to Linux with a proven record of better security than most Linux distros." Your position is that it's simply incorrect to do Bitcoin on any OS but Linux, and I think that is silly, ill-informed, and dogmatic.

You do not need a HW to achieve secure cold storage of Bitcoin. In fact if you are hodling long term HWs are a bad choice as the additional risks they present are not worth it. HWs can be lost, stolen, hacked or malfunction. Learning to to build your own secure cold storage is preferable to buying an expensive gadget touted by a third party upon whom you must place trust and reliance. Learn how easy it is to build and use your own cold storage free of third party HW gadgets- [https://electrum.readthedocs.io/en/latest/coldstorage.html](https://electrum.readthedocs.io/en/latest/coldstorage.html) And always use a Linux OS for any serious Bitcoin computing.

Again you misrepresent what I have said and you repeatedly make assertions without providing any reasoned basis for them. You sound a lot like someone who is essentially a bully, pushing a viewpoint but it is a viewpoint you are not capable of giving a credible and fact based and reasoned argument so instead you resort to belittling and shooting the messenger and misrepresenting the messenger. If you are proposing people invest the time and effort to learn how to use open sourced BSD OS variants then how widely used they are is relevant. It is irrelevant that corporates have used BSD as the basis for creating their own closed source platforms for specific hardware which people may unwittingly use. Linux in the range of variants gives people choice without being corporate captured. Clearly BSD does not provide as much utility for most people as exploring and learning how to use Linux.

C01n_sh1LL

Hey man, I recognize I was a little insensitive with my wording, so I'm sorry for that. I'm not trying to belittle you, just trying to dispel some poor advice you were offering. I didn't answer your post point by point because I was on mobile, and that makes it a real pain to refer back to an earlier post while writing reply. But just to satisfy you, I'll give you a point by point response below: > Windows is subservient to the surveillance state. > > It is riddled with back doors and viruses. What makes you think the major Linux distributions are any less backdoored? Linux certainly has plenty of malware. Your use of the word "viruses" outs you as someone without a strong security background, because viruses are not the main threat in the malware landscape, and have not been for at least 20-25 years. Network-enabled trojans and worms are more typical threats nowadays. And you know what? There's plenty of those on Linux. > Are they free, open source and non proprietary? The various free BSD distros are, it should come as no surprise, released under the BSD license. The major difference between the BSD license and GPL, is that BSD licensed code can be copied, modified, and distributed without releasing source code changes. This is why companies like Sony and Nintendo use FreeBSD forks as OS's for their games consoles. It's also the reason Apple used a fork of the FreeBSD userland as the basis for MacOS X, and later for iPhoneOS/iOS. > How many people have even heard of them? I don't know and it doesn't really matter. A sizeable chunk of the world's population are using variants of these OS's, whether they realize it or not. > Most people are at least familar with Linux. Are they really? How many people know that Linux is not an operating system? You've recommended it in this thread as if it is a specific operating system, but it's not. "Linux" encompasses many distributions. Some are more secure than others. People should use whichever OS they understand well enough to secure from their most realistic threat model. I will maintain that advising a bunch of absolute linux noobs to run their hot wallets on network-connected Linux computers simply isn't great advice. I am saying this as somebody who works with Linux malware on a daily basis. Ignore my opinion at your own peril, lol.

Yeah nah not if you install new Linux OS. Just because you use Microshitware doesn't mean everyone must.

Electrum on a Linux OS laptop is secure as a hot wallet. Ok for small to medium amounts. For the best cold storage learn to build your own cold storage- again only use Linux OS for any serious Bitcoin computing. https://electrum.readthedocs.io/en/latest/coldstorage.html

You don't understand how simple it is to remotely sign without HW. All that is needed is a freshly installed Linux OS on an old laptop or install Linux on a $5 USB card. [https://itsfoss.com/intsall-ubuntu-on-usb/](https://itsfoss.com/intsall-ubuntu-on-usb/) Tragic how dependency upon these proprietary third party HWs prevents people like you from learning more about the way Bitcoin operates and is designed to free us from reliance upon third parties like HW vendors.

mutinomonem

You don't have to check every single hardware wallet in your setup but if you've checked at least 3 hww and they all show the same quorum information; xpubs etc, then things are good. Do a test; send bitcoin from the 3o5 multisig to another address (signing with 3 keys) you will know you have full control. You could further test by signing with the other 2 ("spare") keys. If your multisig is empty, fund it with something and send that back out as a test. If someone has taken over any keys in setup you will know because you won't have enough keys to sign with. The best way to see how it works is to do it. Then you'll know when something is "off". Rather than adding extra wallets into an already big multisig I would recommend a brand new dedicated laptop for each signing device. One laptop with windows. One with Mac. One with Linux. Don't use these laptops for anything else. Just update their OS and wallet software. You would create a txn on one laptop and sign it there. Then download the (PSBT) transaction and either email it or USB or SD card transfer to the next computer and open it in sparrow or electum and sign the next one and then download it again for the last laptop/pc. You could use a different software on each pc/laptop. Eg. Sparrow, Specter, and Electrum. This way you significantly reduce the chances of all three devices being infected by the same malware.

Smytty_for_PM

Anyone else having issues getting transaction notifications to popup in OS/Metamask on ETH Mainnet?

cheerful_afternoon

Yes you can, so you put in your phrase. then you should go down and find "Account Extended Private Key" then download Electrum Wallet from [www.electrum.org](https://www.electrum.org), and ONLY from that website, no where else ! install on a clean computer, then open the wallet. when you first open the wallet, the "create new wallet" wizard opens. go with : Standard Wallet > User a master key and the paste in the "Account Extended Private Key" you got in Ian Coleman's tool and then click next. it will create the wallet for you, and if there are any coins in it, it will show you. again, its very important to have a CLEAN OS for this and download Electrum ONLY from their website www.electrum.org

Yes HWs are a huge risk that is not necessary - problem is they have been so heavily touted that a lot of people have become dependent upon them rather than learning how to remotely sign transactions and create their own cold storage.

Don't move to an exchange as a temporary holding position. That is just asking for your funds to be frozen or confiscated. They'll also charge you extra in fees to withdraw. Do you have a computer or phone that is not used at the moment? It would be better for you to do a fresh install of an OS, preferably Ubuntu, and install Sparrow wallet. Or get Samourai or Blue Wallet on a phone. Create a new wallet from there and move your funds to that. Dont use that computer/phone for anything else and you'll be more secure than using an exchange.

pgh_ski

I would say in general avoid downloading apps that don't have a great reputation, avoid downloading/approving software on your PC from weird sources (torrents, "cracked" software, etc.). If it seems like it's too good to be true, don't install it. Don't ignore warnings from the OS or your browser about untrusted/potentially malicious software or websites. When it comes to critical software like wallets, it's a really good idea to learn to verify hashes and digital signatures. With phones it's harder but also easier as wallets should come from the app store (which has vetting processes in place) - so it's more important to pay attention to number of downloads, reviews, etc. for signs that it's malicious.

Competitive_Hippo_17

Oh okay. Yes there is. Tails OS comes with Electrum by default. I think all wallets nowadays generate a seed. If not, I would definitely be highly suspicious

Piggybacking on the most secure platform is very smart and that is how early internet softwares got successful by realizing they need to piggyback on Windows OS. Bitcoin offers extreme security and from there on your project extends the network by adding usability and functionality

wrathmxer

This is the real answer. Support the network in any capacity you can. Obviously starting with a clean OS for your nose, whichever you choose, is best to ensure no malicious code is running. Having any HW wallet is better than none. There are better devices out there, but if you never connect your HW wallet to the Internet then you will be fine. Even better if the devices you connect it to are also not connect to the Internet. You need to pick the right amount of security vs ease of use for you. You'll find that the more you stack the more secure you'll want to be. It is a journey and you're already well ahead of most.

Lordshaney

Yeah he’s probs the main guys. He’s pretty good. But not a lot of excitement in the space like OS

Zyntra

I would install Tails OS on a USB drive. Launch it on an airgapped machine, like a laptop with a wifi hardware switch, or even better, rip out the wifi chip. Tails OS comes with Electrum preinstalled. Make sure to verify the signature of the download obviously. That way you can generate a wallet that has never touched, nor ever will touch, the internet. You then export the master public key from that offline-created wallet, and can use that one freely on your main phone or computer to look at it. You can even construct transactions, but you can not sign them, as no private keys are held on your 'main machine'. You then need to export the transaction unsigned on a different usb stick, sign it in the offline environment, then export it again to that second usb. Import it in your 'online' wallet. The last step is then to 'broadcast' the now signed transaction. Bit of hassle going back and forth, but about as secure as you can get it without using commercial solution which are more userfriendly. Also, the process gives good understanding and insight of how bitcoin transactions work.

castorfromtheva

Here you'll find your answer. In short make sure bitcoin core is also connected to the network via tor. To do this, follow the steps for your OS shown in the link. After you have setup bitcoin core to also have an onion address and port, use this data on your family's machines to let them connect to your node. https://bitcoin.stackexchange.com/questions/98913/how-to-run-bitcoin-core-as-onion-service-on-windows-ubuntu-and-android

Why not just use an air-gapped HW wallet? Literally no need for this laptop brand and OS discussion considering there are options HW wallets.

This is an area where the solutions are still growing and changing quite a lot. I’m sure there are a handful of startups trying to break into this space, but the subreddit is probably quiet because it’s not something seeing widespread use. The most hands on and cheap way to go is via BTCPay Server. It has many of the features you’re looking for, and has a long track record of being a good product. The challenge with BTCPay is that it requires running a full node + Lightning Network. - On the low end of price, you can run Umbrel on a Raspberry Pi or an older laptop, and you’ll be managing a lot of the Lightning Network operations yourself. Managing inbound and outbound liquidity, opening channels, etc. Unless you want to get elbows deep, it’s not viable for most small businesses. - Start9 is building self-contained hardware/software to run a full node, with greater security and performance. It’s still a full node that will run BTCPay server, so you’ll still have to handle financial operations yourself. The hardware isn’t cheap, but it’s also a better step up from a hobby computer running a feature-heavy node OS like Umbrel. - Voltage offers node hosting, so you can skip the setup and maintenance of your own hardware, you just manage everything remotely. And I believe they also offer services to provide channel liquidity for your node, so that you don’t have to worry about that part. I bet there are standalone channel management services out there for self-hosted nodes, but the combo of hosted node and managed liquidity makes for a compelling sell if I were trying to get a business online. I’m super bullish on the lightning network, but we are still in the early days of it being reliable. And so if you or the business you’re working with are sufficiently orange-pilled, then these growing pains are just part of the process. But I haven’t yet seen the (paraphrase) “one stop, plug and play, maximalist friendly, feature packed, better than fiat” payment system for small businesses. Certainly nothing that I’ve seen yet would be good to onboard mom and pop, small coffee shops, antiques, home decor, etc. That customer demo is going to be a tough sell on working with something like BTCPay until they really have a reason to want Bitcoin in the first place. It requires some patience, some on-site management, and a willingness to work with bleeding edge tech (especially in terms of what their customers will think of it).

Quite a weird take - you can’t say Cartesi is not building. Just a few months ago, Cartesi launched their first dApp on the Ethereum mainnet, an occasion on which they even hosted an AMA in this subreddit. And throughout the year, they participated in all ETHGlobal hackathons, where hackers who built projects with Cartesi became finalists in all editions amongst thousands of builders. They also showcased three games currently on testnet at this weekend’s edition of ETHGlobal Istanbul. Building is surely happening. Cartesi’s VM took almost three years in the works, but it’s currently the only one able to boot a complete Linux OS onto the blockchain with all its libraries, tools, compilers, popular programming languages, etc. As for the comparison with Harmony and BluDAO (was it BluDAO, right?), I don’t think it has anything to do here. But that was pretty much a mess indeed and a flop…

I did it with MyNodeBTC and Start9 (Start OS). It was pretty fun and I just started getting into mixers which you can run yourself. Both are free and require minimal setup/expenses.

I am in Ontario as well. Defnitely worth it. I run and validate all of my transactions through my own node. I runs in the background on a small Raspberry Pi using Umbrel OS.

Scotty_NZ

You can do it with 64GB micro sd off the bat with sync/pruning. It would be an interesting project. I just used Start9 (Start OS) to do my R pi 4 with 64gb micro sd and it went through with no issues. Took a long time though. I’m not sure if the pruning is standard with BTC core, but might be worth looking into to how they do it.

against_all_odds_

Honestly, I don't understand how anyone would manage any crypto on any phone. With exploits like Pegasus really being able to penetrate your phone, this must have been a no brainer. You are only (somewhat) protected if you run a UNIX-like OS. Truly paranoid/serious people should do any transactions only with a Tails USB stick and a private encrypted self-hosted connection.

humblevladimirthegr8

If you just got the wallet without Bitcoin on it, you can wipe the wallet and restore it. If not, try restoring it on another wallet, ideally a physical one but if not you can try a digital one, ideally using a more secure OS like Tails, never connecting to the Internet, and deleting the wallet after validation (Tails wipes itself after shutdown)

Ledger had a scandal where they once said your seed would never be allowed to leave your device. They've done a 180 on that promise. They claim to be open sourcing their OS to calm fears they caused. Seed sharing to third parties can be safely added as a feature if done right. They need optional firmware with these added features. Ledger never reports to the IRS. At least we see no code in the OS that would allow this. Though, Ledger is still not fully open source. Either way, it would make no sense to report. Even if it did, it wouldn't know your Identity. There is no KYC. I personally use Ledger for any asset I actively use with defi. Then I use Trezor, a fully open source device, for the bulk of my assets I rarely touch. Trezor can also leverage defi. It's just not as adopted as Ledger. Remember, your assets aren't actually stored on any device. They are stored on the blockchain. You can literally just generate a seed phrase and move your asset to the private keys derived from those 24 words without even needing to touch any software or hardware wallet. Your assets would be connected to a piece of paper you used to write down your seed phrase. Think of a hardware wallet as a USB drive that stores your user names and passwords of any blockchain you interact with. That's it. Again, wallets do not actually store your funds.

prONoOB1004

Now I am worried about my approach . I am using metamask wallet on a dedicated USB installed OS. I don't do anything there except doing transaction. How safe it is ? Should I switch to hardware wallet ?

Corbimos

Sparrow. Nunchick is great, but mobile is too risky for a big stack imo. You should be running your own node, or at least connecting to it. You should also run your bitcoin stuff on a dedicated device. Mobile is hard to run a node on, and most will use it for other reasons. Run a Linux OS build on a cheap ~$300 PC and use Sparrow. Only use that machine for bitcoin and nothing else.

I genuinely find the conspiracy fascinating. People quickly forgot that Tether settled with the NYAG in February 2021 after a thoroughly investigation. Under the FOIL, Coindesk, Forbes and other news organizations obtained the docs with the reserves relative to the investigation, with statements and portfolio reports issued and confirmed by the banks themselves like [Ansbacher](https://downloads.coindesk.com/legal/C2%20Attachment%20B.pdf?_gl=1*716oqi*_up*MQ..*_ga*MTAwODU4OTI2OS4xNjk5OTgzMDU0*_ga_VM3STRYVN8*MTY5OTk4MzA1NC4xLjAuMTY5OTk4MzA1NC4wLjAuMA) and [Capital Union Bank](https://downloads.coindesk.com/legal/C3%20Attachment%20C.pdf?_gl=1*2h93qk*_up*MQ..*_ga*MTAwODU4OTI2OS4xNjk5OTgzMDU0*_ga_VM3STRYVN8*MTY5OTk4MzA1NC4xLjAuMTY5OTk4MzA1NC4wLjAuMA). Tether is backed as 2021, too bad right? Then the narrative shift, the Chinese CM conspiracy: “half of the assets are hold in commercial papers, they’ll likely default”. As of 2022 with rising int rates Tether reduces commercial papers exp to nearly 0 and roll into Treasuries and the narrative gets back to “Tether is clearly unbacked for reasons”. I mean, how can you not be entertained?

Bitcoin 0.1.0 was windows only, Linux support was introduced in 0.2. You can still run the most current Bitcoin on Windows. Don't store anything sensitive like a seed phrase on your computer regardless of the OS.

zer0fks

Running an OS you don’t understand is far worse than one that’s better because someone online said so. And a node shouldn’t be a wallet; you connect your wallet to a node. Run your node over tor so you can anonymously connect from anywhere and nobody can tell where your node is.

And if there’s one thing we humans are known for when it comes to using computers, it’s that we *always* update our OS immediately upon receiving notice to do so. I can’t foresee any potential issues with setting up an arbitrary deadline for coin holders to move their coins or lose everything instantly. It’s simple; Just avoid being hospitalized, impaired, stuck in traffic, incarcerated, *or for any infinite number of reasons be physically unable to get to your computer before the deadline*, and you’ll be fine.

zuilli

The way you're phrasing it makes it look like this would be made agressively to fuck old coins but we could just have a transition period where you're expected to migrate your own coins to a new system and if you don't then it will be prone to being hacked. Same logic as security updates for OS, you can keep using windows XP forever if you want but you're open to exploits that will never be patched.

Very very bad management of keys. They should NEVER BE ON AN INTERNET CONNECTED DEVICE!!!! You would be infinitely better with just metal, hammer, stamping kit, and some dice with Ian Colman on a usb stick running on Tails OS on an eternally offline computer… use the dice to generate your keys and you can get a xpub from Ian Colman tools. Smash the devices after you get your keys into metal WITH A PASSPHRASE YOU WILL NOT FORGET… you can use Shimmer Secret Sharing (on Ian Colman for 24 word keys) and keep the metal backups in separate locations. People have too much faith in password managers etc. they have ZERO BUSINESS handling bitcoin keys… it should never be on an internet connected device becomes it will just be a glorified hot wallet still.

I am not worried about that personally. The better ones will thrive. If kraken doesn't come up with something great, it will fall behind. We already have some emerging layer 2 protocols such as Fuel, Cartesi. The latter i believe has one of the strongest fundamentals out there! Cartesi's VM(Virtual Machine) can boot an entire Linux OS, meaning developers are not limited to a specific programming language as is the case with other blockchains and they can use any mainstream language, tools, and libraries for building DApps.

gbitg

Being offline does not guarantee 100% secrecy of your seed. I bet Electrum uses the random number generator of the underlying OS, so if the generator on that particular OS version was biased (remember LibreSSL on Linux?), it might well mean that the seed is "recoverable" by a third party without any connection interaction with the system.

guryfitze

Thanks for your reply. One other question: My understanding is that it is running a Linux OS off the SD card. How do we know it isnt writing spurrious log files to the card that may contain the seed words? Or is there a way to make a SD card read-only. Wouldnt it be better to be running off a Linux CD since it is read-only?

guryfitze

How does SeedSigner protect your 24 words from someone that gets physical access to the device if it has no secure element or any encryption of the OS?

HWs are exposed to risk of hacking, theft, malfunction and loss. You are not gaining monetary self sovereignty by reliance upon these proprietary gadgets. However the good news is you can build your own cold storage for free and its much more secure. In addition running your own node gives even better security. And last but not least, always only use linux OS when working with serious quantities of Bitcoin. https://electrum.readthedocs.io/en/latest/coldstorage.html

Calius1337

A cold wallet is a wallet that is on an air gapped device that’s not connected to the internet at all. Ideally a PC using a very secure OS like OpenBSD or NetBSD (although that is not a requirement for a cold wallet.) So in theory it is pretty safe from malware as long as you never connect it to the outside world.

SmoothGoing

Tails is an anonymization OS, used to browse the web without revealing your IP or leaving any traces on the PC it is booted on. It is not designed to manage cryptographic secrets. If you enable connection to the internet to use electrum it is no better than just running electrum on your home PC.

It is slightly more safe than Electrum on a persistent OS, but not safe compared to a hardware wallet. You'd have to manually load the seed each time, which opens you to the (small and unlikely) risk of a hardware keylogger. It means that you have to worry about the people who live with you. If you have less than $1000, not worth buying a hardware wallet. You could use this to learn more about self custody and practice recoveries since each time you need to spend you are essentially doing a seed recovery. Once you have enough that you can buy a hardware wallet for less than 10% of your stash, buy a hardware wallet. Don't be lulled into doing DIY hardware wallet with large amounts. Plenty of sob stories from people who did that.

Blur: Better UI. Backed by VC money to eat OS's share. Token dropped for VC to take profits. However, they've spoken about erc1155 for a while and yet nothing is done yet. My comments about them do not speak to token prices, as they are generally used to pay VCs which will dump them once unlocked to take profits (just like IPO from tradfi). OS: Only knows how to respond when competitions take action (like a child responding to provocation), and still can remain shit. Admittedly website does not break as often as before, but improvements on UI is next to nothing after 3 years. No realistic competitors in NFT space (at the moment) aside from these two.

And how! Even back in the heyday, I looked at OS and saw an ocean or crap. There was some NFT of a real statue and was asking for like 5-10k and I was puzzled why someone would buy that. The statue wasn’t that impressive to begin with let alone an NFT version of it.

Depends country and OS, try Relai, or Pocket app (Pocket app is still Bitkipi for IOS).

Well when people find out the block chain is secured from hackers using Ones Compliment OS... I imagine Blackrock will be losing a lot of money! Sell your cryptos boys and girls, the security created by us has been exposed. Ones Compliment not only stops hackers it also allows those who know the ability to hack into the blockchain and move coins without an exchange. I tried to settle this a different way but if you are going to screw the guy who helped create crypto for you to use.... You should probably try and help him out with donations instead of telling him he is a fraud. 2.8 Trillion, lets see how long it takes them to hack into the block chain now :-)

[Xubuntu 22.04 LTS](https://xubuntu.org/download/) for the OS, [Bitcoin Core v25.0](https://bitcoin.org/en/download) for the node software, and [Sparrow Wallet v1.7.9](https://sparrowwallet.com/download/) for the wallet software. As for tips, take your time. Sure you could get a node setup and starting to sync in an hour or so, but imo it's better to learn WHY you're doing what you are doing v.s. just hitting the next button over and over till it's done. Don't get discouraged after trying for a day and then give up. The reality is, to get it properly setup involves many steps and configuration settings to be changed, so just try and knock one step out every other day or so. So what if it takes you 2 weeks to get your node up and running. Once it's done, it's done, and you're helping to decentralize the hardest asset on the planet. Which benefits us all.

>Umbrel OS [https://umbrel.com/](https://umbrel.com/) is this the device i need to set up my own node? cheers!

>You're joking yourself if you think Linux is an accessible OS for the average person If you mean it's difficult to learn, I agree. I have spent 20 years learning about it and I still consider myself an intermediate user. If you mean it's hard to get started, I strongly disagree. Anybody with a computer can run linux within a few minutes.

Been running core since v 0.15. Have upgraded hardware/ OS several times. Required a VM with dedicated SSD for past few years. Also mined for a bit, but the fans on the GPU annoyed me so I stopped… hmmm…

Search for BTCSessions in Youtube. My recommendation, use Start9 OS.

You can get into very complex was to run a node. Depending what OS you have. Windows is fairly easy run a node. Download Bitcoin-qt, adjust some settings and let it roll for a few hours a day or week.

MaverickT92

have you tried Umbrel OS?

HashMeOutside_

Just install raspian OS and install like that. You could look up the snapcraft snap store and sudo install bitcoin core [https://snapcraft.io/install/bitcoin-core/raspbian](https://snapcraft.io/install/bitcoin-core/raspbian)

I'm not paid by any hardware wallet manufacturer, never have been. I have deployed hardened Linux in large scale security environments for literally decades. The first version of Linux I used, I downloaded from Linus' university FTP server at funet.fi in 1993, on 1.4M floppy disks. I started hardening Linux systems in the late 90s and building commercial bastion hosts for financial services companies in the City of London. And yet, I'd rather use a hardware wallet than spend hundreds of hours building and maintaining a DIY Linux solution because I know what that actually entails. HWs are more complex? Poppycock. Most are about as minimalist as you can get with hardware, firmware, and software without going to an ASIC. Linux is a general purpose kernel and OS that takes a *lot* of work to cutdown to a secure profile. I know because I did that work for years professionally. You are out of your depth. There's nothing wrong with that if you're willing to learn new things. But spreading nonsense to newbies is not cool. Take a seat, please, before you do more damage.

solomonsatoshi

Bullshit. HWs are far more complex and risky than building your own on a Linux OS. The only experts pushing HWs are those paid by HW manufacturers.

A lot of people have lost their coins by following this kind of advice and doing a DIY hardware wallet on consumer hw/sw. Most notably a core developer. When security experts with decades of experience who have built operational air-gapped systems tell you to not do this, there's a reason. I'm sure the person who left this comment will continue to "advise" this despite all the experts and professionals saying otherwise. Don't listen to them. They are experiencing maximum Dunning Kruger because what they know about OS security is just enough that they don't know what they don't know. Massive overconfidence.
