In just a few days, bitcoin will activate one of its most significant upgrades, Taproot. Taproot is impressive in many different ways, but perhaps its most remarkable aspect is that it removes the last barriers to using arbitrary scripts in bitcoin.

For years, the bitcoin community has produced novel ideas on how to improve the experience of using bitcoin by tapping into its scripting capabilities. These ideas range from scaling improvements (payment channels, channel factories), to privacy enhancements (atomic swaps, coin pools), to security and recovery guarantees (time-lock vaults, social recovery).

Despite the potential benefits of these improvements, most bitcoin wallets are still using some variation of the original pay-to-public-key script. Why is this?

The answer lies in the lack of efficiency, privacy, and interoperability when using other scripts.

Efficiency and privacy at the protocol layer

While using arbitrary scripts has been possible since 2011 (when BIP13 introduced P2SH), practical limitations have strongly disincentivized their use in end-user products. Using more powerful scripts meant paying higher transaction fees — sometimes prohibitively high. Even worse, uncommon scripts resulted in an almost complete loss of on-chain privacy: you can search the blockchain and locate all transactions ever made with any particular script.

This is precisely the problem that Taproot solves. By combining Taproot and Musig, arbitrary scripts are now indistinguishable from regular pay-to-public-key scripts. What’s particularly fascinating about Taproot’s approach is that it aligns individual economic incentives (paying less in fees) with increased privacy for all users.

By making arbitrary scripts efficient and private, Taproot has the potential to unleash a wave of latent innovation in the ecosystem. But this innovation won’t click into place until it reaches the hands of users. And this happens at the wallet layer.

Recovery interoperability at the wallet layer

Recovery interoperability is a crucial property of self-custodial wallets: it guarantees that users can recover their funds even if the wallet provider disappears. Since the introduction of mnemonics in 2013 and standard derivation paths in 2014, we’ve had a mostly interoperable recovery mechanism for importing and sweeping funds in pay-to-public-key scripts.

However, mnemonics rely on all wallets using a single key with the same, single script: pay-to-public-key. If we want to keep (and improve!) recovery interoperability in a world of payment channels and multisig vaults, we need to work on new backup and recovery mechanisms.

Enter output script descriptors (BIP380 to BIP386). Designed by Pieter Wuille and Andrew Chow, descriptors provide a human-readable way to express any combination of keys, scripts, derivation paths, and address types without ambiguity. These descriptors allow a program to discover and spend funds from any given script in a fully interoperable manner.

Wallets can now produce their output descriptors and immediately gain recovery interoperability with other descriptor software, such as Bitcoin Core. Many of them are already doing so!

Output descriptor upgrading

While descriptors solve recovery interoperability for any given wallet setup, these setups change over time. As bitcoin evolves, new address types and scripting capabilities emerge, while ideas like payment channels mature — think eltoo.

Traditionally, wallet providers introduced these improvements by prompting users to create a new wallet. This mechanism places a heavy burden on users. They need to write down a new set of mnemonics to keep safe in cold storage, then move some funds to the new wallet (paying on-chain fees), and end up with their funds fragmented in different wallets based on their address type and script.

In a world of rapidly evolving technologies, we need to design a foolproof descriptor upgrading mechanism that lowers the friction of adopting new address types and scripts. How can a wallet backup be both secure and easy to upgrade?

Muun’s Emergency Kit was designed for this. The Emergency Kit is a PDF document that contains your private keys and output descriptors. All sensitive material is securely encrypted with a cold recovery code. As a result, the Kit is harmless by itself and safe to store in the cloud.

Each time a new descriptor is needed, the user can easily upgrade the Emergency Kit. By upgrading before ever using the new descriptor, funds are recoverable at all times. Meanwhile, the cold recovery code remains fixed and safe in cold storage.

Since multiple descriptors can coexist in the same wallet, there’s no need to fragment funds or make transactions to move them. Users can choose whichever address type they prefer, and adopt new ones as the ecosystem evolves.

Taproot and Musig in Muun

Today we are releasing the new descriptor upgrading mechanism and using it for the first time with Taproot and Musig. Stay tuned for an in-depth walkthrough of Muun’s new output descriptor.

Designing a foolproof script upgrading mechanism was originally published in Muun on Medium, where people are continuing the conversation by highlighting and responding to this story.

We're happy to share that Muun is moving to a new open-source model, much more aligned with the values of the bitcoin's community and our mission.

As announced in the Muun 2.0 launch, we are committed to building a bitcoin wallet that makes self-custody easy and safe for everyone in the world. Since the launch, several people from the bitcoin community have reached out to us and shared their concerns about our open-source model. We've come to understand that self-custody cannot truly exist without easy auditability and openness, which motivated us to make this change.

As of today, Muun's native apps can be entirely built from the code published in our public repository, our software is licensed as MIT, and we are working on having reproducible builds.

How we got here

From early on, we knew that auditability was a key component of self-custody, and our code has always been published in a public repository. At the same time, we were (and still are!) worried about this software being used to distribute malicious copies that steal users’ funds. Sadly, this is an all-too-real risk for newcomers and clearly goes against our mission.

For this reason, when we released Muun 1.0 we decided to publish the apps' source code without the UI layer. This would make it easy to audit the relevant parts of the codebase, but make it really difficult for scammers to replicate a malicious version of the app.

Many things have changed since then. Reproducible builds are now viable for mobile applications distributed through the official app stores. App store providers have expressed their willingness to work with us to identify and remove scams from their stores. Finally, we now have a larger user base helping us detect and report scams.

All this encouraged us to review our past decision. We believe that having verifiable builds is the only way to provide true self-custody. Muun is now ready to take its auditability to the next level.

Roadmap

Today we are happy to share that both the Android and iOS apps can be entirely built from the source code. We are currently working to have reproducible builds for the Android application, which will be available soon. We are also looking into how to build the iOS application deterministically, which is much harder and, to our knowledge, hasn't been done before. It will take some time, but we are excited about bringing this to iOS as well.

Finally, as we go forward, we’ll be moving towards a much more open development process, in order to make auditabilty easy and true self-custodianship a reality. This will take us time, but we’ll keep moving in that direction.

Thanks for your support and feedback! We'll keep up the hard work.

Muun’s New Open Source Model was originally published in Muun on Medium, where people are continuing the conversation by highlighting and responding to this story.

Hoy, anunciamos el lanzamiento de Muun 2.0, una gran iteración del monedero para bitcoin y lightning. Lo que más nos entusiasma es que se acerca mucho más a nuestra visión: construir un monedero de bitcoin que haga que la custodia propia sea fácil y segura para todos los usuarios de bitcoin del mundo.

Muun 2.0 llega en un momento crucial. Bitcoin está bajo la mirada atenta de varias personas, muchas de las cuales son nuevas en el ecosistema. Ahora es el momento de mostrarles lo poderoso y simple que bitcoin puede ser. Porque, aunque bitcoin como tecnología pueda ser increíblemente compleja, bitcoin como solución es maravillosamente simple.

El abismo

En la adopción de cualquier tecnología exitosa existe un abismo entre los early adopters y los usuarios mainstream. A medida que lanzamos Muun 2.0, bitcoin está cruzando su propio abismo.

Si estás leyendo esto, probablemente seas un early adopter. Has estado siguiendo a bitcoin por un tiempo. Te educas del tema. Incluso educas a otros. Valoras la custodia propia. Ves cómo bitcoin está, finalmente, sucediendo.

Ahora piensa en la última vez que le enseñaste bitcoin a alguien. Probablemente, ellos sean parte de los usuarios mainstream. Escuchan sobre bitcoin principalmente de ti. Usan los productos que les recomiendas. Siguen, parcialmente, tu consejo de no mantener dinero en los servicios de custodia, pero ‘MtGox’ ni siquiera les suena familiar. Están emocionados de probar ‘esa cosa del bitcoin’.

Hay una buena posibilidad de que bitcoin se vea algo diferente del otro lado del abismo. Los early adopters y los usuarios mainstream se preocupan por cosas diferentes. Esto le da forma a los productos y servicios que utilizan. Sin embargo, hay un aspecto de bitcoin que no podemos permitirnos perder en el camino: la custodia propia.

La custodia propia se suele entender como tener el control de tus claves privadas. Esto pasa por alto un punto clave: tener tus claves no será suficiente si el bitcoin en sí se vuelve lo suficientemente difícil de usar.

Imagina un escenario en el que las comisiones de bitcoin se disparan (sí, ahora están altas, pero imagínalas 10 veces más altas). ¿Seguirán los usuarios mainstream eligiendo un monedero de custodia propia en lugar de realizar pagos baratos en servicios de custodia? Probablemente no. Lo mismo ocurre con la recuperación del monedero. A menos que cambiemos algo, el miedo a perder su dinero triunfará sobre el miedo a la confiscación.

Cuando las cosas se ponen difíciles, la custodia propia parece ser algo que se puede relegar, algo dispensable. Tuvimos un adelanto de este fenómeno ocurriendo en los primeros días de lightning. Incluso algunos de los usuarios más experimentados de bitcoin eligieron la UX en lugar de la custodia propia para sus monederos de lightning. El problema con la custodia propia es que, al igual que los derechos humanos, uno no se da cuenta de que lo necesita hasta que ya es demasiado tarde.

Como Argentinos, estamos dolorosamente conscientes de lo que sale mal cuando esto sucede. Lo que otros llaman “riesgo potencial”, nosotros lo llamamos “historia”. En un mundo con cada vez menos efectivo, el mero hecho de que puedas tener la custodia completa de tus bitcoins lo cambia todo.

Creemos que con suficiente trabajo, el bitcoin de custodia propia puede tener una experiencia de usuario aún mejor que los servicios de custodia.

Muun 2.0

En Octubre del 2019, lanzamos Muun 1.0 con soporte para enviar pagos en lightning. Desde entonces, muchas personas comenzaron a elegir a Muun como su monedero principal de bitcoin, y la recomendaron a sus amigos y familiares. Recibimos muchos comentarios durante este tiempo, incluidas las cosas que te encantan de Muun, las cosas que prefieres que sean diferentes y las cosas que quieres que sucedan. Los escuchamos a todos.

Muun 2.0 es un replanteamiento completo del monedero basado en lo que aprendimos con Muun 1.0. Es el resultado de muchos meses de arduo trabajo y, sin embargo, se siente sólo como el comienzo de un viaje emocionante. Estamos entusiasmados de compartirlo contigo, junto con nuestro nuevo sitio web.

¡Esperamos que te guste!

Anunciando Muun 2.0 was originally published in Muun on Medium, where people are continuing the conversation by highlighting and responding to this story.

Today, we are announcing the launch of Muun 2.0, a big iteration of the mobile wallet for bitcoin and lightning. What excites us the most about it is that it is much closer to our vision: building a bitcoin wallet that makes self-custody easy and safe for every bitcoin user in the world.

Muun 2.0 arrives at a crucial time. Bitcoin is under the watchful eye of many people, many of whom are new to the ecosystem. Now is the time to show them how powerful and simple bitcoin can be. Because, though bitcoin as technology can be incredibly complex, bitcoin as a solution is wonderfully simple.

The chasm

In the adoption of any successful technology, there is a chasm between the early adopters and the mainstream users. As we launch Muun 2.0, bitcoin is crossing its own chasm.

If you are reading this, you are probably an early adopter. You have been following bitcoin for a while. You educate yourself about it. You even educate others. You value self-custody. You see how bitcoin is finally happening.

Now think about the last time you onboarded someone to bitcoin. They are probably part of the mainstream. They hear about bitcoin mainly from you. They use the products you recommend them. They kind of follow your advice on not keeping money in custodial services, but ‘MtGox’ doesn’t even ring a bell. They are excited to try the ‘bitcoin thing’.

There’s a good chance bitcoin will look somewhat different on the other side of the chasm. The early adopters and mainstream users care about different things. This shapes the products and services they use. However, there’s one aspect of bitcoin we can’t afford to lose on the way: self-custodianship.

Self-custodianship is often understood as having control of your private keys. This misses a key point: just having your keys won’t be enough if bitcoin itself becomes sufficiently hard to use.

Imagine a scenario where bitcoin fees skyrocket (yes, now they are high, but 10x them). Will mainstream users still chose a self-custodial wallet over making cheap payments in custodial services? Probably not. The same goes for wallet recovery. Unless we change something, the fear of losing their money will trump the fear of confiscation.

When things get hard, self-custodianship seems like something you can relegate, something you can live without. We had a sneak peek of this phenomenon happening with lightning early on. Even some of bitcoin’s most experienced users chose UX over self-custody for their lightning wallets. The thing with self-custody is that, much like human rights, you don’t realize you need it until it’s too late.

As Argentinians, we are painfully aware of what goes wrong when this happens. What others call ‘potential risk’ we call ‘history’. In an increasingly cashless world, the mere fact that you can have complete custody of your bitcoin changes everything.

We believe that with enough work, self-custodial bitcoin can have an even better UX than custodial services.

Muun 2.0

Back in October 2019, we launched Muun 1.0 with support for sending lightning payments. Since then, many people have started choosing Muun as their main bitcoin wallet while recommending it to their friends and family. We got a lot of feedback during this time, including things you love about Muun, things you would rather be different, and things you want to see happen. We heard you all.

Muun 2.0 is a complete rethinking of the wallet based on what we learned with Muun 1.0. It’s the result of many months of hard work, yet it feels just like the beginning of an exciting journey. We are psyched to share it with you, together with our fresh new website.

We hope you like it!

Announcing Muun 2.0 was originally published in Muun on Medium, where people are continuing the conversation by highlighting and responding to this story.

We are thrilled to announce the release of Muun iOS, a non-custodial wallet for Bitcoin and Lightning Network. After some months of testing our app on TestFlight (big shoutout to our testers!), we are ready to provide a seamless experience for Bitcoin and Lightning Network for iOS users.

The days when you had to give up the custody of your money for usability are gone. Muun is a UX-first mobile wallet that allows you to send fast and cheap Bitcoin and Lightning transactions, without losing custody of your funds at any moment.

Want to have the Lightning experience? In Muun you can do it right away! Just scan or paste the lightning invoice you want to pay and follow simple steps. No technical knowledge required, no loading of a lightning wallet or waiting for channel opening, zero channel management, and no split balances between off and on-chain wallets.

Muun users have one single wallet with Bitcoin’s full power: on-chain and off-chain transactions. And all of them are 100% non-custodial.
Just as in the Android version, users can sweep funds by themselves by exporting their keys and using an open-source recovery. Both apps are LND-based and can be audited.

Our vision on Lightning Network

At Muun, we loved the Lightning Network at first sight: we love learning, working, and writing about it. We also love doing the dirty work: running nodes, working on reliability, managing channels. However, we know that pretending users to do the same is asking too much.

Here’s how we envision Lightning in the future: You make a bitcoin payment. It is fast, cheap, and non-custodial. The payment goes either on-chain or off-chain, according to what it is more convenient. You don’t need to decide on this. You might not even notice it. You are just making a simple bitcoin payment.

We want to bring part of this experience to users today and have designed our current experience and roadmap to fulfill this vision.

Who Is Building Muun?

Muun is built by a team of 12 people working from Buenos Aires, Argentina. Our drive to work with blockchain technologies started back in 2013 when it was hard to get paid for your work as a remote developer because of strong controls on foreign currencies.

What started as a natural and pragmatic response to deeply flawed institutions, ended up as a commitment to build the most secure and easy to use non-custodial wallet.

Muun Releases Non-Custodial Bitcoin and Lightning Wallet for iOS was originally published in Muun on Medium, where people are continuing the conversation by highlighting and responding to this story.

Edit: As of June 2020, this feature has been disabled.

Some months ago, we released Lightning payments in Muun. They are instant, 100% non-custodial and don’t require any channel configuration.

Since then, we have received requests from users who wanted to use this feature to top up their lightning nodes and get connected to ours. Therefore, we improved the feature to make it faster and easier to use for this purpose.

As of today, you can easily top up your Lightning node from your phone using Muun. Just generate an invoice of 150,000 sats (or more) from your node and pay it with Muun. To be extra sure, we suggest you extend the expiration time of your invoice to 2 hours.

The transaction you are sending is a submarine swap, consisting of an on-chain transaction to a swap provider, that pays the lightning invoice with an off-chain transaction. Both transactions happen atomically, so the whole process is completely trustless.

There are two aspects of this use case that make it different from other Lightning payments in Muun: 1) The amount being sent is probably larger ( >150,000 sats) and 2) The destination node is probably less connected than a merchant or a Lightning App. Because of this, chances are there won’t be a well-funded route to your node. This won’t be a problem. Instead, Muun will automatically open a channel to your node and you will receive the money off-chain.

The result is that you will top up your node gaining outbound capacity to pay in the Lightning Network. At the same time, you will get connected to one of our nodes, that is both well-connected and well-funded.

Confirmation times and fees

Making a Top Up requires four confirmations from the network, meaning the whole process will take approximately 40 minutes. This differs from instant Lightning payments because there isn’t an existing well-funded route at the moment of the payment. A channel must be open on the spot. The fees associated with this service are to cover all the on-chain transactions needed to manage the channel.

Are you running your own node? Give it a try and tell us what you think!

Actualización: luego de este anuncio, ha habido un montón de mejoras en nuestra implementación de Lightning. Las comisiones pueden llegar a ser tan bajas como 1 satoshi (total)!

En los últimos meses, Lightning Network atrajo la atención de muchas personas que realizaron sus primeros pagos en la red. En este contexto, todos estamos ansiosos por encontrar productos y servicios que nos permitan entender más y probar la red de Lightning. Las billeteras son de los productos más buscados.

A partir de hoy, puedes realizar pagos sin custodia en la red de Lightning usando Muun. No requieren de ninguna configuración de canales: todo lo que necesitas hacer es asegurarte de tener bitcoins en tu billetera y escanear la factura de Lightning que deseas pagar. Muun detectará que se trata de una factura off-chain y te guiará a través del pago.

Por detrás de un flujo de pago fácil y sencillo, está ocurriendo un submarine swap. Los submarine swaps permiten a usuarios pagar facturas off-chain con bitcoins on-chain, a través de un proveedor de swaps. El proveedor de swaps no tiene la custodia de tus fondos en ningún momento.

Esta tecnología fue creada por Olaoluwa Osuntokun y Alex Bosworth de Lightning Labs. Los submarine swaps fueron muy bien recibidos en la comunidad, con gente listándolos entre las aplicaciones más innovadoras de Lightning Network.

Todos tus fondos seguirán estando en una única billetera en Muun, y notarás que el proceso de pago es muy similar al de un pago on-chain, con dos excepciones: 1) la mayoría de los pagos serán instantáneos 2) aparecerán nuevos fees en el detalle de la transacción.

Tu factura off-chain se pagará de manera inmediata, exceptuando casos muy particulares. Esto es porque, a pesar de haber una transacción on-chain, no se pedirán confirmaciones en la gran mayoría de los casos.

En el detalle de pago, verás dos comisiones distintas 1) La “Comisión de Lightning”, que incluye los costos de ruteo de la componente off-chain de tu pago 2) La “Comisión del Swap”, que incluye la comisión por la primera transacción on-chain al proveedor de swaps.

Hasta el momento, las billeteras de Lightning han experimentado con distintas soluciones que sacrifican o bien la usabilidad, o la custodia de fondos. En las primeras billeteras de Lightning, los usuarios tenían que realizar el manejo manual de sus canales para mantener la custodia propia de sus fondos. Las billeteras más recientes, en cambio, han sacrificado la custodia de fondos por parte de los usuarios, para liberarlos de la configuración de canales.

En esta implementación logramos mantener ambos aspectos, la usabilidad y la no custodia, y el sacrificio se ve en los costos, dado que las transacciones aún pagan la comisión de la red de Bitcoin.

Actualización: luego de este anuncio, ha habido un montón de mejoras en nuestra implementación de Lightning. Las comisiones pueden llegar a ser tan bajas como 1 satoshi (total)!

En Muun estamos trabajando para lanzar una billetera de Lightning completa: custodiada por los usuarios, fácil de usar y con transacciones rápidas y baratas. Como Lightning aún está en su etapa inicial, nos tomará un tiempo hasta llegar a ese estado. Creemos que está bien sacrificar algunos aspectos, siempre y cuando la experiencia general sea buena y no implique comprometer alguno de nuestros valores más fundamentales, como la no custodia de fondos.

Estamos contentos de poder proveer una manera simple de pagar en Lightning desde el comienzo. Seguiremos trabajando para proveer una excelente billetera de Lightning.

Pruébala ahora!

Pagar en Lightning Network más fácil que nunca was originally published in Muun on Medium, where people are continuing the conversation by highlighting and responding to this story.

Edit: since this announcement, there have been a ton of improvements to our Lightning implementation. Lightning fees can now be as low as 1 satoshi (total fee)!

Over the last couple of months, the Lightning Network attracted a lot of attention and many people made their first payments. We are all eager to find the products and services that allow us to learn about and experiment with Lightning. Wallets are at the forefront of this search.

As of today, you can make non-custodial Lightning payments using Muun. It requires zero channel configuration: all you need to do is make sure you have bitcoins in your wallet and scan the Lightning invoice you want to pay. Muun will automatically recognize it as an off-chain invoice and guide you all the way through the payment.

Underneath a super easy payment flow, a submarine swap is occurring. Submarine swaps allow users who hold on-chain bitcoins to pay off-chain invoices through a swap provider. The swap provider doesn’t have custody of your funds at any moment.

This technology was created by Olaoluwa Osuntokun and Alex Bosworth from Lightning Labs. Submarine swaps have been very well received in the community, with people listing them among the most innovative features in the Lightning Network.

You will still have your funds in one single wallet in Muun, and the whole payment process is the same as an on-chain payment, except for two differences: 1) most payments will be done instantly 2) different fees will appear in your transaction detail.

Your off-chain invoice will be paid instantly, except for very particular cases. Although there’s still an on-chain transaction involved in the swap, confirmations won’t be required in the vast majority of the cases, so the Lightning invoice will be paid instantly.

In your payment detail, you will see two different fees: 1) “Lightning fee” are the routing costs of the off-chain component of your payment, and 2) “Swap fee”, includes the first on-chain transaction to the swap provider.

So far, the market has been experimenting with trade-offs between usability and non-custodianship. The first Lightning wallets gave up usability, in terms of channel configuration, in exchange for non-custodianship. The more recent wallets sacrificed non-custodianship in return for zero channel configuration.

In this implementation, the trade-off is in costs since transactions still pay for an on-chain fee. In talks with users, we learned that the current motivation for paying in Lightning is to learn about and support the technology. Therefore, we thought this was a reasonable trade-off for the first implementation.

Edit: since this announcement, there have been a ton of improvements to our Lightning implementation. Lightning fees can now be as low as 1 satoshi (total fee)!

At Muun we are working hard to release a full Lightning wallet: non-custodial, with great user experience, and cheap and fast transactions. Because Lightning is in its early days, it will take some time until we reach there. We are okay with sacrificing some aspects, as long as the overall experience is good and we do not compromise on our core values such as non-custodianship.

We are happy to provide you with a simple way of paying via Lightning in a trustless way since the early days. We’ll keep working hard on bringing a great non-custodial Lightning wallet for everyone.

Try it now!

Lightning Payments Easier Than Ever was originally published in Muun on Medium, where people are continuing the conversation by highlighting and responding to this story.

Edit: As of September 2020, this feature has been disabled.

Muun and Trezor users can now safely transfer money between their mobile and hardware wallet. This new setup levels up the security and usability of your bitcoins, while reducing the number of times your hardware wallet is connected to your computer.

As expected, your private keys stay right where they are. The private keys in your Trezor are never copied to your mobile phone, nor exposed in any way.

Hardware wallets are a well-known solution to secure the money you don’t intend to spend for a while. The private keys to spend these funds are stored offline, making your funds less accessible, as with any long-term savings. Some operations, such as running a firmware update, or making a withdrawal, require the plugin of your Trezor. Every time your cold storage connects to a computer, it becomes less cold. Therefore, more frequent operations, like depositing money or checking balances should be done wirelessly.

By pairing your Muun and Trezor, you can optimize the experience for both of your wallets and keep your cold storage colder. Pair your Trezor with Muun to:

1. Easily transfer money from Muun to Trezor, without reusing addresses or connecting your Trezor. Receive money on the go and transfer it directly to your savings account, at any time!

2. Safely transfer money from Trezor to Muun, by approving the transaction from your Trezor (no OTG cable needed). Load your checking account with money you need to use right now!

Sometimes money belongs in different places: some is kept on hand, in a checking account, and savings in a savings account. Muun users now have the ability to organize bitcoins into their various non-custodial wallets. Try the new set up and get closer to being your own Bitcoin bank!
