I did a walkthrough/tutorial for the Cobo Vault. TLDW: pretty solid, open source, secure chip, optional bitcoin only firmware, air gapped txs, interoperable with Blue Wallet/Wasabi/Electrum/BTCpay to name a few. Thumbs up.
Is there a tutorial for dummies how to do this? FWIW: you could have spent a few bucks on the cheapest possible notebook and create an airgapped offline electrum there, import your mnemonic, create a watch only wallet for your online device and safely sign the transactions from your offli /r/Bitcoin

Guardá tus Bitcoin en un Pen drive: aprendí a configurar la Wallet Electrum en un pen drive con Tails y me pareció tan fácil, seguro y práctico que escribí un tutorial para que les pueda servir a otros.
So this is what software I currently use for privacy, would like some opinions if possible: Starting with my cellphone, my device is a Google Pixel 3A XL with GrapheneOS flashed, I have the following apps installed: F-Droid and AuroraOSS (as my app stores), NewPipe (youtube client), Vanadium (web browser), Tutanota and K-9 Mail (for e-mails), OsmAnd+ (for maps), Joplin (notes), Open Camera (camera), OpenBoard and Mozc for Android (Keyboard and Japanese Keyboard), Aegis Authenticator, KeePassDX (password manager), LibreTorrent (torrent client), Librera PRO (pdf/epub/mobi reader, I don't own a Kindle nor want to own one so I use my cellphone to read), Tachiyomi (manga reader), Signal (for messaging), Vinyl Music Player, VLC, Simple Gallery Pro and Simple Calendar Pro (I prefer them over stock Graphene options) and I also use Electrum and Samourai (Bitcoin Wallet) and Monerujo (Monero Wallet) I also have OpenVPN (for VPN) and use a private DNS for ad and tracking blocking (provided by my VPN provider) I have 3-4 PCs, will go over every single one of them: my main PC is a desktop PC (that I built myself) that I mainly use for working and other tasks. It runs Artix Linux (basically Arch Linux without systemd), I use UFW as my firewall (denying all incoming and also denying all outgoing only allowing what is useful) and I also use AppArmor Profiles, I disabled IPV6 and SWAP, configured my VPN connection as well on network settings and I currently run OpenVPN on my computer (my VPN provider allows for multi-hop cascade through OpenVPN in which I can create a custom VPN cascade up to four servers, each consecutive hop re-encrypts my traffic and assigns me a new IP address) and I've also set disk encryption on installation (have set in all of my computers) As for software: I use Mozilla Firefox as my web browser (I set it to always be in private mode, unchecked suggestions for browsing history, bookmarks, and open tabs, I've also disabled the Firefox data collection in settings and block dangerous and deceptive content, I use DuckDuckGo as my search engine, I use Firefox Home as my default as my homepage. The rest of my tweaks were done in about:config (using privacytools.io site tweaks + geo.enabled = false, network.cookie.lifetimePolicy = 2 and dom.security.https_only_mode as true which are not listed on the site) and the only addons I use are uBlock Origin on Hard Mode and Decentraleyes), KeePassXC (password manager), VIM (use it as a Text Editor and as an IDE for coding), LibreOffice (for working stuff), GIMP (image editor), VLC, qBitTorrent and Tutanota's Desktop Client and Thunderbird (for e-mails) I also use KVM/QEMU for virtual machines (usually in case I wanna test some distro or use Tails/Whonix) For my gaming PC (also a desktop I've built myself) I run Manjaro KDE on it, the only apps I have in the system are Firefox (same settings as above), OBS and KVM/QEMU (which I use a Win10 virtual machine for games, there are tutorials on YouTube on how to do so if you're interested). I have the same firewall settings as above, using AppArmor as well and I've also disabled IPV6 and SWAP, I run OpenVPN on it as well as my VPN DNS settings on network settings. I also use different mouse and keyboard on both my PCs and never mix them together. My other 2 PCs are both laptops, one is a Acer Aspire Nitro I've bought for work (in case I need to work while in a trip or if I wanna work outside etc), it has the same settings and programs as my main PC but I run Gentoo on it. The other laptop is an old ThinkPad that runs Slackware on it, but I rarely use it and this laptop is most of the times not with me for safety reasons. For some other devices and stuff: I have an Asus RT-AC86U router with OpenWRT flashed on it that I also run OpenVPN config files (this one coming from another provider, I use two VPN providers, on in my PCs and the other in my router), I have a Ledger Nano S as a hardware wallet for both Bitcoin and Monero (most of my cryptocurrency is there, I use hardware wallet for hodling purposes and as my emergency funding) and I have LOTS of USB flash drivers (all of them for Linux Live ISOs purposes), I also have a Nintendo Switch Lite (only gaming console I have, although have not been playing that much on it recently) that I only connect to the internet in case I need to download some updates or play online and after I'm done I immediately disconnect it from the internet. Some other privacy habits I have are: I don't own any smart device like Smart TVs (I've been more than 10 years now without watching TV, doesn't even bother me), Smart Fridges or Dishwashers that connect to your internet, ROOMBAS, Smart Home etc, I keep all my money on crypto (and I have a small amount in gold as well, but I rarely invest on it, all my gold is stored in a manual safe here in my apartment) and I only have like, 10 bucks or so in my back account (as soon as I receive any money I just left the necessary in my account to pay bills and put all the rest on crypto, I try to pay everything on crypto or cash), I RARELY use cloud storage, but if I need to, I go with NextCloud and encrypt all my files with VeraCrypt before uploading it, all my VPN services were paid with Bitcoin (I try to pay everything with crypto as previously said) and I never write directly into any website, I usually write my text on a text editor, copy it and paste it on the website (needless to say that I don't use mainstream social media as well) So, what do you guys think? anything that you would add your recommend me? (before anyone mentions about self-hosting a DNS server using Pi-hole on a Raspberry Pi, I'm actually thinking on doing it in a near future) EDIT: forgot to mention that I don't watch YouTube on PC on youtube site, I mostly watch youtube's videos on invidio.us and only use the youtube site for watching live streams honestly. And I also barely go outside with my smartphone (only if I really need to) and I usually keep it away from my computers etc. EDIT 2: also another thing: I covered all my laptop's webcams with black electrical tape, I have a Logitech C922 Pro webcam for my desktop PCs but rarely use it, and when I need to use it, I unplug it as soon as I'm done with it.
Hi, I recently bought a ledger nano X and want to have my bitcoin saved here. I am using the Electrum wallet and have no clue as to what to do (at setup I did not choose back up with hardware device as I did not have one then). Similar posts I've read (Electum and ledger nano S) either refer to instructions on the ledger website (which only describes how to use a new Electrum wallet and not with an existent wallet) or to simply 'send' from Electrum to ledger (I presume this has a fee). I have watched tutorials on restoring Electrum to see if I can then choose to back upon a device but that will only create a new wallet and I won't have my funds there. Any suggestions? There is nowhere in the current wallet setup that allows to add a hardware device. My ledger nano x is all setup and ready to be used. Thanks!
How to make a mobile wallet connect to my full node through Electrum Personal Server?
I have Bitcoin Core (full sync) and Electum personal server with basic configuration in linux (mint) but I don't have enough technical knowledge on how to connect to mobille wallets like bluewallet, samourai, breadwallet (BRD), coinomi etc, all of them unfortunately require that connect to an electrum server instead of our own node (direct enter IP address). But unfortunately I can't find any tutorial on the internet, could someone please tell me what to do? Detail: Some wallets like Bitcoin wallet for android (schildbacth wallet) and BRD allow you to connect to your full node just by adding your IP address (which would be much easier and more convenient), however my node is configured with tor and these apps do not add address .onion. Is it possible to do this only using the electrum personal server or EPS only connects locally and does not allow more than one connection? Do I have to install another electrum server like ElectrumX? Do I need to create an alias certificate to connect to these mobile wallets?
Motivation: Why the need to connect these mobille wallet apps to my own node since these apps automatically connect to their own servers, and obviously will require a lot of technical knowledge in addition to time?? Because I care a lot about my privacy and I believe that most users that run full node not only to help the network, but to validate and transmit their own transactions instead of relying on third parties for this function. One of my motivations is also because I have a full node and I want to live up to the almost 300gb that occupy my HDD, I have already managed to make my Electrum wallet to connect to my full node through EPS, now my goal is to connect mobille wallets with my own node that have this option.
The easiest way is to print the QR code on paper with the mention “Bitcoin donations” at the top and your Bitcoin receipt address at the bottom and paste it into your work.
Download thistemplate and add your QR code and receiving address (as above). Check that the address shown corresponds to the QR code by scanning it with a smartphone. Optional: It is recommended to add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you. Once the sheet is printed, you can paste it on your next street artwork. Prefer flat and smooth surfaces for better adhesion of the poster. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you. - The second method is to create a QR code stencil and use a spray bomb to put it in your work. There are 2 possible cutting techniques: A manual technique that requires some basic DIY. The second technique is to prepare the visual Photoshop and Illustator then to call a provider who will cut the stencil for you. 1st technique — Manual: To make yourself the stencil, you will need a rigid sheet, a cutting support, a cutting scalpel, Masking Tape, a black felt pen, a clamp and a thin square grid. To make the QR code stencil by hand, see thistutorial . Once the stencil of QR code is made, make a stencil with the mention “Donate Bitcoin” and add it to the first stencil to understand that this is your Bitcoin reception address. You can write it yourself or use this template (below) that you can print and overlay your rigid sheet. Once your stencil is ready (“Donate Bitcoin” + QR code), you can put it on your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that the stencil is integrated into the signature of the work to understand that the gifts are for you. 2nd technique — Stencil cutting by a provider: To create a QR code stencil, it is imperative that all the background of the visual is connected to allow cutting of the stencil, for this, it is necessary to go to a site that generates QR compatible stencil code like qrcode-zebra.com Once on the site, choose the “Text” tab and paste your Bitcoin receipt address and click on “Generate QR code”. Your QR code will appear, but the design will not be the right one. There are a few changes to make. In the “Choose patterns” tab on the left, click on the first pattern (which looks like a square grid), then in “Choose eyes”, click on the first box (the basic square “eyes”). Then, in “Set colors”, choose the color black. Optional: if you wish to add your logo or signature, you can add it in “Add logo”. The file should be as simple as possible, in black with transparent background that connects (compatible with a stencil cut). Now that the QR code is ready, you can retrieve it with a screenshot or click on “Dowload PNG” and give your email address to receive the QR code as a PNG file. Then, on Photoshop, it is necessary to couple the grid of your QR code with thismodel so that the mention “Donations in Bitcoin” and the 3 “Eyes” square of the QR are compatible for a stencil cut. Use overlapping layers and erase old “eyes”. Finally, download this special stencil typography and use it to enter your Bitcoin receipt address used on your QR code. Check that the address shown corresponds to the QR code by scanning it with a smartphone. It is strongly recommended to also add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you. Once the visual is ready and fully compatible for stencil cutting, you can vectorize it in Illustrator and save it in EPS or AI format. Last step, send this file to aproviderwho makes stencil cutting. It’s up to you to choose the provider that best suits your location, price and time. Choose a format that suits your job. For large frescoes, larger formats (A2) are preferable, and for smaller works, smaller sizes (A4). Once you receive the stencil, you can affix it to your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you. 3 — Last step, communicate. Let all those who follow your work know that they can now support you financially by sending you Bitcoin donations on your Street Art works. You can use the means you have available, your contacts, your website, your social networks … To help beginners, here is a tutorial that explains how to buy Bitcoin. To track the transactions you receive, you can open your wallet regularly to see your balance. To receive a notification when you receive a donation, you can use your Wallet to track transactions at an address of your choice. The public can also see your balance received on your address thanks to blockchain explorers. Here is the balance of a donation address: 3Pboy9ucGEdQUHNu2rrC6RGq4jouRc4Grb If you receive a lot of donations, it is a good opportunity to communicate on the amount received. Good luck and good creation! FAQ Why use Bitcoin? The money you receive is 100% in your possession because you are the sole owner of your private key (recovery phrase, or “Seed”), unlike other centralized means of payment (Banks, Paypal, Ulule, Patreon. ..), Bitcoin happens totally of intermediary of confidence. How do I use Bitcoin? Thanks to your wallet you create a private key and a public address. The private key (recovery phrase, or “Seed”) is a bit like the key to your digital vault that you need to keep only for yourself. The public address is your RIB to receive transactions, you can share it publicly without problem. How do I exchange my bitcoins for USD? You can at any time send your bitcoins on an exchange online ( Coinbase …) to convert them into currency (Euro, Dollar …). You need to create an account on one of these exchange exchanges, convert your funds into the desired currency and then make a transfer to your bank account. A faster solution may be to use a centralized service provider that offers a Bitcoin wallet connected to a credit card to spend your bitcoins directly ( Wirex , Coinbase …).

A tutorial for Tails linux, to stay safe on Internet.
I'm not so sure this will be a help or not, quite sure that official guide is more reliable than this. anyway that's what I have here. If this article contains any kinds of misleading or error, please let me know in the comments. A tutorial for tails linux, to stay safe on the Internet. In today's circumstances, it's good to put more effort on maintain a low profile on Internet, or atleast learn how to do that. If you already have a computer at home, you need to consider to use Tails linux if safety is what your concern about. Access to https://tails.boum.org/ then follow download instructions. The idea of tails is, it will anonymize your entire connection on Internet by using Tor network. So no one will discover your identity without lots of effort. Not only that, once you do shutdown your device, it no longer holds any information. That means, other one can't find any evidence from your device. Also if you still want to storage some text on tails, The easiest way is hide that in online email account. At first, open text editor that preinstalled in tails. https://www.reddit.com/tails/comments/bm65w7/tails_faq_what_happened_to_the_pgp_clipboard_in/?utm_medium=android_app&utm_source=share Then, follow the instruction to encrypt your text by passwords and paste it on email account through tor browser. Do not use that account to communicate to others, just keep it in secret. https://tails.boum.org/doc/encryption_and_privacy/gpgapplet/passphrase_encryption/index.en.html If you are about to send messages through email, this instruction could be handy. https://tails.boum.org/doc/encryption_and_privacy/gpgapplet/public-key_cryptography/index.en.html You needs to learn about PGP first, tho.use XMPP is the either easier or safer plan. You can encrypt other type of files by using Archive manager(give a right click on the file), but the computer gets freeze by that occasionally. I strongly recommend to use Veracrypt hidden volume instead of build a Persistent storage feature, or LUCKS encrypted drive for linux that available on tails for both send/storage purposes. In that way, you'll get two of passwords for one encrypted storage. If you are forced to reveal your password by others, you have a option to reveal a fake one. On top of that, if you use another USB for that purpose, you don't have to slow down Tails itself. Persistent storage is tends to be fragile, I occasionally toast an entire data during excessive use. https://www.veracrypt.fen/Hidden%20Volume.htmlhttps://tails.boum.org/doc/encryption_and_privacy/veracrypt/index.en.html You need to use other OSs for create new volumes. Linux is safer than windows I guess, but it takes an effort. IIRC, you should check "I use hidden volume" radio button during type the password. Otherwise your hidden password doesn't simply work. Don't get confused by that. Not only that, Tails has the Mac address spoofing function by default. Mac address is the unique identifier for your device. https://en.m.wikipedia.org/wiki/MAC_address That function also increases anonymity on Internet. it's important when you go outside because even if you killed GPS function on your devices, it still leave a Mac address on wifi router or 3G/LTE cellular module nearby. So someone still can trace your location. Also just in case if your government decides to not allow you to connect tor network, you should read this article first. https://tails.boum.org/doc/first_steps/startup_options/bridge_mode/index.en.html But if every each of instruction seems failed to helps you, bring your device(with Mac address spoofing function) outside and connect to the Free wifi. https://freetoursbyfoot.com/where-find-free-wifi-london/ It's relatively safe since either of wifi or device doesn't leave the information that directly leads to you, but be aware on surveillance camera nearby. don't stay there too long, or use one spot too frequently. I know laptops is too cumbersome to carry around, you have a option to choose something like a windows tablet, a stick pc along with touch screen or a Tv box. not sure on which kind of stuff do the best job unfortunately. For communication, you need to build the safest/robust assembly point on Internet. The very best option available is XMPP Pidgin chat client. It's pre-installed in the tails. https://tails.boum.org/doc/anonymous_internet/pidgin/index.en.html As you expected, you can start a group chat. https://superuser.com/questions/1440212/is-there-any-way-to-create-a-group-in-pidgin-like-in-whatsapp There is couple things you can't do on Tor network or tails Linux. First, you should read these articles. https://www.hongkiat.com/blog/do-donts-tor-network/amp/https://tails.boum.org/doc/about/warning/index.en.htmlhttps://2019.www.torproject.org/docs/faq.html.en Since tails is lots more robust than Tor browser bundle on windows, you can ignore the most of issues in Tor browser. Still you have to aware the risk on this. Not only that, couple of things is getting harder to achieve through Tor. At first, some website like Twitter, Reddit or YouTube tends to reject to create an account. If that was just a couple of exit nodes, maybe restart the browser might do the trick. https://tor.stackexchange.com/questions/19536/cant-use-reddit-on-tor-what-do-i-do But if entire exit nodes are rejected by provider, Web based proxy gives you a chance. If that doesn't work, I'd say you should find someone who will to post your messages on viral media. Secondly, even if you using tails, thats not means you can pay for something anonymously. If you need to use paid Web base proxy or whatever you want, it's also safer to use anonymous cryptocurrency such as Zcash or monero. not sure how safe are they, pre-installed wallet(Electrum) only supports bitcoin. so you need to use web based wallets. Or if someone donated a bitcoins to your anonymous wallet, it's safe to use that one through Tor.
I’ve been seeing a lot of repeated questions being asked every day so an updated FAQ/Megathread to address all of those questions will be detailed here. If we are missing something, please feel free to let us know and we will add it. We will try to edit this posting as more information becomes available. Keep in mind the official Bitcoin Private Support portal has now been launched. We have a live chat feature to chat with support, as well as a knowledge base. Please visit the portal at support.btcprivate.org and use the knowledge base’s search function before asking other users. Snapshot/Fork FAQ
When is the snapshot date? Snapshot date will take place on February 28th 2018. The exact moment the snapshot will be taken WILL NOT be announced as a TIME, rather it will be announced as a specific block height. Whatever time happens to be when the block height occurs is whatever time the snapshot is taken. This is to address users who are asking for a specific time or time zone. Once the block height has been mined, the snapshot would have been successfully completed instantly. Users can choose to wait until the NEXT block after the snapshot block has been mined for peace of mind. Once again, the exact block height has not been announced yet. We can only estimate the exact block height as we get closer to the snapshot date. Announcements will come via posts on Reddit, Discord, TwitteFacebook, Telegram and the official BitcoinPrivate Twitter account which is the primary source of all official announcements.
Why can't we announce a block height instead? Why did we choose to announce a date? Block height is not announced for a reason. Keep in mind this is a DOUBLE FORK. BTC and ZCL. 2 Block heights need to be announced. It's impossible to determine the exact block heights so far away from the snapshot date, because BTC and ZCL both have different block time intervals, and the total hashing power of the entire network of BTC and ZCL are changing so rapidly that it is extremely hard to determine a block height in advance, so we decided to pick a date for when we expect the snapshot block to occur instead. We need to determine the exact moment both block heights of BTC and ZCL will coincide in order to get an accurate and successful snapshot. Also, do not forget that 2 simulated snapshot runs have already been completed and validated by the team some time ago, so the process has already been proven.
When is the Hard fork date? The Hard fork will occur approximately 2 days after the snapshot, on March 2nd, 2018.
Is the snapshot on the 28th for ZClassic or for Bitcoin? The snapshot will be taken simultaneously for both ZCL and BTC. Block heights will be announced for both.
Do I need to hold my ZCL until the snapshot or fork? Snapshot. As soon as the snapshot occurs you are free to do whatever you like with your ZCL and you will still receive your BTCP.
What will happen to ZCL after the Bitcoin Private Fork? Current ZClassic's wallet server nodes (Electrum) will still continue to be supported after the fork, and the core dev team will be actively supporting BTCP, whereas the community can choose to further support development for ZCL.
How does Bitcoin Private rewards/claims work? BTCP Coins will be distributed on a 1:1 ratio. Example: (1 ZCL = 1 BTCP.) (1 Bitcoin = 1 BTCP.) (1 ZCL & 0.5 BTC = 1.5 BTCP.) The total combined amount of ZCL and BTC you own at the time of the snapshot will grant you eligibility to claim the same combined amount in Bitcoin Private. You do NOT need to hold a full amount of a coin. You can own partial amounts of ZCL/BTC.
Do I have to store my ZCL in transparent addresses or private addresses to participate in the fork? Any kind of address will be supported through the fork. However, as of Feb. 13, the ZCL electrum wallet only supports transparent addresses.
Are Segwit-enabled wallet addresses for Bitcoin (BTC) supported for the fork? We have confirmation that BTC being held on Segwit enabled addresses WILL BE supported through the fork.
How do I claim my BTCP? More information will become available as we get closer to the snapshot date. An official dedicated guide will be released. In summary, users will need to export a copy of their private key for the corresponding wallet/wallet addresses that hold their ZCL funds at the time of the snapshot. Users can then take the private key and import it into the Bitcoin Private Electrum wallet once it is released in order to claim their BTCP coins. The same goes for Bitcoin holders. **In case exchange(es) support will be announced, users will not need to do anything. The exchanges will automatically credit your account with BTCP. This may vary, so again, please stay tuned for official news regarding this.
BTCP/ZCL Exchange and Wallet Support
Which exchanges will support the fork? The team CANNOT talk about exchange support at this time. Once the support is announced, we will let users know ASAP. All we can say is that the BTCP team has already applied to Binance, as posted on BTCP's Twitter. This is the only thing we can discuss. Binance strictly forbids teams from disclosing IF or WHEN/DATE they will list on Binance. But they allow teams to announce that they HAVE applied for listing, to ease the urge to talk about it. See the official tweet from the CEO of binance. Please do not spam and repeatedly ask this question. News will come as time passes.
Is Bitcoin Private supported by LedgeTrezor Hardware wallets? Currently it is not supported yet because of a technical implementation that the team has not worked on yet because it doesn't take priority. However, the team will be working on BTCP with regards to hardware wallets after the fork, so stay tuned for announcements.
When is the Bitcoin Private wallet being released? Currently the Bitcoin Private Electrum wallet is being developed and rigorously tested by the team. We expect the BTCP Electrum wallet beta to be released slightly before or slightly after the fork occurs. Stay tuned for news.
What other wallets will support Bitcoin Private? The Bitcoin Private Electrum wallet will serve as the “Lite-Client” without having to download the entire blockchain. The team will be working on a GUI version of the BTCP wallet (similar to the java based ZClassic Swing wallet) shortly after the fork. More announcements to come in the future. Coinomi will also support Bitcoin Private.
