It emerged in the early 2000s and is based on RFID (Radio Frequency Identification) technology. <br/><br/>It has had a variety of uses since its inception, from contactless payment with credit cards and cell phones, to data transfer between devices, access to events or locations, fast pairing of Bluetooth devices, and object identification.<br/><br/> It is also used in public transportation cards and in the Internet of Things (IoT) industry, where it enables interaction between smart devices.<br/><br/>How can we combine it with Bitcoin?<br/><br/>The combination of Bitcoin and NFC offers a number of interesting possibilities, such as:<br/><br/>Contactless payments: users can use their smartphones or other NFC devices to make payments in stores and other establishments. <br/><br/>Funds transfers: Users can transfer funds between each other using their NFC-enabled devices. Many Bitcoin wallets already allow this option.<br/><br/>Data storage: Although not very secure as they can be read with any NFC device, if we have an NFC card or chip we can &#34;record&#34; inside it our recovery words, a Bitcoin address to receive payments or simply any other information we wish. Remember to keep it well guarded to avoid information leaks. <br/><br/>Bolt Card NFC Lightning Network<br/><br/>The Bolt Card is a physical card that can be used to pay with Bitcoin through the Lightning Network.<br/><br/>Physical NFC cards such as the Bolt Card mark a new step in the adoption and use of Bitcoin as a payment and exchange instrument, breaking down barriers of limited usability and speed that were one of the negative aspects that worked against the use of Bitcoin as a means of payment. <br/><br/>Thanks to the second layer, known as Lightning Network, Bitcoin has a mechanism that helps it not only to increase its speed to levels even higher than traditional payment instruments, but also opens the door to a universe of innovations that allow the end user to easily use it as a payment instrument without complications.<br/><br/>To use the Bolt Card, the merchant, or your counterpart, only needs to generate the corresponding charge from their phone or NFC device and we bring the Bolt Card close to them so that the charge is debited from it.<br/><br/>Key features include:<br/><br/>⚡ Lightning payments.<br/><br/>⚡ NFC / Contactless<br/><br/>⚡ Send payments in BTC, at the exchange rate of any Fiat currency.<br/><br/>Challenges<br/><br/>There are some challenges associated with the combination of Bitcoin and NFC. For example, the security of NFC devices is a major concern, as they could be hacked to steal funds or personal information. <br/><br/>In addition, the widespread adoption of Bitcoin and NFC is still in its early stages, so it can be difficult to find places to use these technologies.<br/><br/>Despite these challenges, Bitcoin and NFC have the potential to revolutionize the way we make payments, transfer funds and authenticate ourselves. As these technologies develop and become more widely adopted, we are likely to see an even wider range of applications for them.<br/><br/>I hope I&#39;ve been helpful to everyone! <br/><br/>Let me know if you know of more uses for NFC and what context you&#39;ve used it in. Let me know in the comments. I read them...<br/><br/>#bitcoin #nfc<br/><br/>Versión en español:<br/><br/>Bitcoin y NFC<br/><br/>Bitcoin ya lo conocemos, sabemos qué hace, sus características y cuál es su objetivo, pero el NFC, que es y cómo podemos ligarlo a Bitcoin?<br/><br/>¿Qué es NFC?<br/><br/>NFC (Comunicación de Campo Cercano o Near Field Communication en inglés), es una tecnología inalámbrica de corto alcance que permite el intercambio de datos entre dispositivos. Surgió a principios de la década de 2000 y se basa en la tecnología RFID (Identificación por Radiofrecuencia). <br/><br/>Ha tenido diversos usos desde su creación, desde el pago sin contacto con tarjetas de crédito y teléfonos móviles, hasta la transferencia de datos entre dispositivos, el acceso a eventos o lugares, el emparejamiento rápido de dispositivos Bluetooth, y la identificación de objetos.<br/><br/> También se utiliza en tarjetas de transporte público y en la industria del Internet de las cosas (IoT), donde permite la interacción entre dispositivos inteligentes.<br/><br/>¿Cómo podemos combinarlo con Bitcoin?<br/><br/>La combinación de Bitcoin y NFC ofrece una serie de posibilidades interesantes, como:<br/><br/>Pagos sin contacto: Los usuarios pueden utilizar sus teléfonos inteligentes u otros dispositivos NFC para realizar pagos en tiendas y otros establecimientos. <br/><br/>Transferencias de fondos: Los usuarios pueden transferir fondos entre sí utilizando sus dispositivos con NFC. Muchas carteras de Bitcoin ya permiten esta opción.<br/><br/>Guardar datos: Aunque no muy seguro pues pueden leerse con cualquier dispositivo NFC, si tenemos una tarjeta o chip NFC podemos “grabar” en su interior nuestras palabras de recuperación, una dirección Bitcoin para recibir pagos o simplemente cualquier otra información que deseemos. Recordar que hay que tenerlo bien guardado para evitar fugas de información. <br/><br/>Bolt Card NFC Lightning Network<br/><br/>La Bolt Card es una tarjeta física que se puede usar para pagar con Bitcoin a través de la red Lightning Network.<br/><br/>Las tarjetas físicas NFC como la Bolt Card marcan un nuevo paso en la adopción y uso de Bitcoin como instrumento de pago e intercambio, rompiendo barreras de limitada usabilidad y velocidad que significaban uno de los aspectos negativos y que jugaban en contra de la utilización de Bitcoin como medio de pago. <br/><br/>Gracias a la segunda capa, conocida como Lightning Network, Bitcoin cuenta con un mecanismo que le ayuda no solo incrementar su velocidad a niveles incluso superiores a instrumentos de pago tradicionales, sino que también abre la puerta a un universo de innovaciones que le permiten al usuario final tener la facilidad de usarlo como instrumento de pago sin complicaciones.<br/><br/>Para usar la Bolt Card solo basta que el comercio, o tu contraparte, genere el cobro correspondiente desde su teléfono o dispositivo NFC y nosotros acerquemos la tarjeta Bolt para que se debite ese cobro de ella.<br/><br/>Entre las principales características destacan:<br/><br/>⚡ Pagos mediante Lightning<br/><br/>⚡ NFC / Contactless<br/><br/>⚡ Enviar pagos en BTC, al tipo de cambio de cualquier moneda Fiat<br/><br/>Desafíos<br/><br/>Existen algunos desafíos asociados con la combinación de Bitcoin y NFC. Por ejemplo, la seguridad de los dispositivos NFC es una preocupación importante, ya que podrían ser hackeados para robar fondos o información personal. <br/><br/>Además, la adopción generalizada de Bitcoin y NFC aún está en sus primeras etapas, por lo que puede ser difícil encontrar lugares donde utilizar estas tecnologías.<br/><br/>A pesar de estos desafíos, Bitcoin y NFC tienen el potencial de revolucionar la forma en que realizamos pagos, transferimos fondos y nos autenticamos. A medida que estas tecnologías se desarrollen y se adopten más ampliamente, es probable que veamos una gama aún más amplia de aplicaciones para ellas.<br/><br/>¡Espero haya servido de ayuda a todos! <br/><br/>Dime si conoces más usos del NFC y que contexto lo has usado. Déjame saber en los comentarios.

It is advisable to use them for small amounts and daily transactions, lock them with a password as secure as possible and never leave them unattended. If they are not going to be used for a while, I recommend deactivating them. <br/><br/>Dedicated applications are usually a bit more &#34;secure&#34;, as they tend to follow the policies of the operating system in which they operate and are not always exposed to the Internet. Generally in these some more advanced security features are implemented that are not possible or are more difficult to achieve than in a browser. Nowadays there are solutions that allow us to have &#34;cold&#34; wallets in our cell phone or pc and never connect them to any network.<br/><br/>Here are some of the tips I practice:<br/><br/>1- Keep the software always updated.<br/><br/>2- Keep our private keys in places only known to us (be creative).<br/><br/>3- If we use antivirus solutions, keep up to date with their updates.<br/><br/>4- A lot of common sense when surfing the Internet, do not trust: verify.<br/><br/>5- Use self-custody and FOSS solutions as much as possible.<br/><br/>As a summary and in my personal opinion, dedicated applications are &#34;safer&#34; than those of a browser. It is us as users, with our sense of belonging and security, with daily study and a lot of self-improvement, who must always be alert to any danger that may be lurking in the shadows to get our private keys, never trust. <br/><br/>For you, what are your main concerns or considerations when choosing between a browser-based wallet and one with its own Bitcoin application? Which one do you think is more secure?

Its creator is <a href="https://t.me/Hirokazu88">https://t.me/Hirokazu88</a> who has created this marvel of a bot.<br/><br/>To make use of it, all you have to do is click on start bot and you get a small but effective help:<br/><br/>Welcome to myloop bot !!!<br/><br/>Here you can swap Bitcoin LN⚡️ to Bitcoin onchain<br/><br/>To start a new swap, use the command:<br/><br/>➡️/loopout amount_sats onchain_address onchain_fee_sats_per_vbyte<br/><br/>where:<br/><br/>💰amount_sats: The amount of sats you want to receive onchain<br/><br/>⛓onchain_address: Your onchain bitcoin address where you will receive your sats<br/><br/>onchain_fee_sats_per_vbyte: The fee in sats/vbyte used in the transaction to send you your sats<br/><br/>For example:<br/><br/>➡️/loopout 100000 bc1qpr9zlcw2efuja66wde9ma5cx5hj2qjgk2guwrg 2<br/><br/>This command will return you an invoice that you can pay over LN⚡️<br/><br/>🆕NEW: You can use the command /loopout2 instead of /loopout to get an invoice with the exact amount that you specified.<br/><br/>Current fee is 0.3% (3000 ppm) + onchain_fees<br/><br/>As you can see, it is very easy to carry out the exchange operation. Always remember to be aware of the fees of the moment so that our transaction does not get &#34;stuck&#34;.<br/><br/>If you have questions or want to learn more about the bot or the project, I encourage you to join their support group (<a href="https://t.me/+rqwdS33pH0oxNTk0">https://t.me/+rqwdS33pH0oxNTk0</a>) or write directly to the developer, they will be more than happy and willing to help you.<br/><br/>Have you used a similar bot on Telegram?

One of these is Replace-By-Fee (RBF), which allows senders of an unconfirmed transaction to increase the fee to incentivize miners to confirm it more quickly. To use RBF, you need to have marked the original transaction with a sign indicating that it can be replaced with a higher fee. Not all Bitcoin wallets support RBF, so this option may not be available to all users.<br/><br/>Another technique is Child-Pays-For-Parent (CPFP), which allows recipients of an unconfirmed transaction to increase the transaction fee. This is achieved by creating a new transaction that spends the output of the unconfirmed transaction, but with a higher fee. This new fee applies to the entire set of transactions, incentivizing miners to confirm both the original and new transaction.<br/><br/>In addition, there are transaction acceleration services that will try to include your transaction in the next block that is mined.<br/><br/>One of the most popular is ViaBTC:<br/><br/><a href="https://www.viabtc.com/tools/txaccelerator">https://www.viabtc.com/tools/txaccelerator</a><br/><br/>It has 2 ways to carry out this action, one free and one paid. The free one allows us to enter our transaction ID every 1 hour.<br/><br/>Needless to say, as it is a third-party service, they do not guarantee that your transaction will be confirmed more quickly and may involve additional risks, our transaction ID will give away (although they do not know who we are), if they will know everything related to said transaction.<br/><br/>The ideal is to use a Wallet that allows the Replace-By-Fee (RBF) or Child-Pays-For-Parent (CPFP) in case we ever find ourselves in trouble, some of these can be Samourai Wallet, Sparrow Wallet, Bitcoin Core, Electrum and BRD.<br/><br/>Have you used transaction acceleration services such as Replace-By-Fee (RBF) or Child-Pays-For-Parent (CPFP), and which wallets do you know that use this option?<br/><br/>Let me know in the comments.

Sometimes for liquidity reasons, for safekeeping or just to test, we have to use some exchange service or exchange that can be decentralized or not.<br/><br/>The service that I use from Cuba and that works great is:<br/><br/><a href="https://fixedfloat.com/">https://fixedfloat.com/</a><br/><br/>What is FixedFloat.com? It is a cryptocurrency exchange service.<br/><br/>I use it mostly because:<br/><br/>1- No KYC or bullshit. <br/>2- It&#39;s fast and easy to use.<br/>3- It exchanges Bitcoin Lightning to Onchain and vice versa.<br/>4- The exchange rates almost always fit my budget.<br/>5- It works for Cuba (Maybe it is your country you should use VPN).<br/>6- Efficient and fast customer service<br/><br/>It is important to remember that, although services like FixedFloat can be useful, they also involve certain risks. By using a third-party service, you are trusting that they will manage your assets securely and efficiently. Therefore, it is always crucial to do your own research and fully understand any service you decide to use.<br/><br/>What about you, which service(s) do you use to exchange Bitcoin Lightning to Onchain and vice versa?<br/><br/>Let me know in the comments, I read you and we learn together!<br/><br/>#Bitcoin 2023-11-24T19:45:31Z https://njump.me/nevent1qqsq95egth22he2vpne5p8g09s5m4k6pn4kq2qep34agp2w8nh0mftczyqs9899hkvxpvzmvnz5xfdjjw7yj9p36x5s4t5s4l3zensl3rr4mx8cvpj5 My experience with MUUN Wallet and why we shouldn&#39;t use it.<br/><br/>Whether you are a new Bitcoiner, or with more or less experience, for sure you have heard or used MUUN wallet at some point. Today I&#39;m going to tell you my experience with that wallet and why I stopped using it.<br/><br/>Some time ago, in a galaxy far far away ...... Ah, no, sorry, that&#39;s another topic...<br/><br/>Some time ago, and following the practice of searching and doing my own research, looking on Youtube for the best Bitcoin wallets, I found that many Youtubers were recommending MUUN wallet as &#34;the perfect solution&#34; for Bitcoiners. So I decided to install it and try it out.<br/><br/>The first thing that shocks me is their way of recovering the key seeds, it is not the traditional way, sure you know that it is recovered with 8 combinations of random letters and numbers + a pdf that they provide you, which seemed to me, I do not know, very strange, I was very suspicious about that, because if they tell me that they are self-custody and on the other hand they give me a pdf + email recovery, it sounds not credible, right?<br/><br/>I was a bit suspicious about that way of giving us our self custody, but I decided to give them a vote of confidence and start using it (always with small amounts of sats of course).<br/><br/>After 2 months of use apparently everything was going great when in this same year (2023) the news of the ordinals spread in the Bitcoin network. That&#39;s when the nightmare began!<br/><br/>When trying to send X amount of sats using the Lightning network (LN) as the service had completely collapsed!<br/><br/> Unbelievable as it shouldn&#39;t (supposedly) affect the high fees on the main Bitcoin blockchain to LN transactions.<br/><br/>I took it upon myself to investigate further and the discovery is completely unheard of. In short: MUUN uses &#34;submarine swaps&#34; for their LN transactions, this means they are not purely LN, they rely on the mainnet to be able to move sats on LN.<br/><br/>With Onchain transactions it was worse all around. MUUN is supposed to do the conversions from the LN network to Onchain and vice versa, and of course charge its fee for its use, but it should not be as high as the amount it wanted to charge in those days when the Bitcoiner world was in turmoil when transaction fees were over 200 sat/vB.<br/><br/>The agony lasted several days with the service down or under maintenance, luckily I was just testing and didn&#39;t have many assets there.<br/><br/>That is my bitter experience with MUUN and why I decided not to use it or recommend it to anyone.<br/><br/>I hope my talk was helpful and encourages you to do your own research every time.<br/><br/>Let me know in the comments which Bitcoin and LN wallets you use and your experiences with them, I&#39;ll read you and we&#39;ll learn together!<br/><br/>#bitcoin #wallets #nostr 2023-11-23T14:28:21Z https://njump.me/nevent1qqswt4j5tlwtm5t6pdfkdzpt9k8ypvzcgzays02u4nuthndj5wl94pgzyqs9899hkvxpvzmvnz5xfdjjw7yj9p36x5s4t5s4l3zensl3rr4mxqpv9ut In reply to <a href='/nevent1qqsdfx9nqzvlsanclpatxjfcs6ere4wasza49kvjy0d4jdwvlutgz6cw6qwwt'>nevent1q…qwwt</a><br/>_________________________<br/><br/>It seems to me that it is already working according to their Twitter account.
