Muun utiliza scripts avanzados de bitcoin para su modelo de seguridad (con multi-firma), y para permitir transacciones instantáneas y más económicas (con lightning).

Las mnemonics, también conocidas como frases semilla, son un gran mecanismo para crear respaldos de claves privadas, pero carecen de otra información necesaria para gastar fondos multisig y lightning de forma independiente. Tener sólo una mnemonic significaría que tu bitcoins podrían ser congelados fácilmente.

Nosotros creemos firmemente que la custodia propia de fondos es fundamental. Por lo tanto, creamos un Kit de Emergencia, aprovechando nuevos estándares como output descriptors, para brindarte la completa custodia de tus bitcoins.

Custodia propia: ¿cuándo era suficiente tener únicamente una mnemonic?

Durante los últimos años¹, el modelo de seguridad de la mayoría de monederos de custodia propia se podía resumir…

Muun uses advanced bitcoin scripts for its security model (with multisig) and to enable instant and cheap transactions (with lightning).

Mnemonics are a great backup mechanism to store private keys but lack other information required for spending multisig and lightning funds independently. Having just a mnemonic would mean your bitcoin could be easily frozen.

Self-custodianship is at the core of everything we do. Therefore, we built an Emergency Kit, leveraging new standards like output descriptors, to provide you with full custody of your bitcoin.

Self-custody: When was a mnemonic enough?

For the last years¹, you could summarize the security model of most self-custodial wallets as:

  1. Your wallet created a master private key. …

When talking about the Lightning Network, it is often said that money is “locked up” in payment channels. The reason for this expression is that when you have money in a payment channel you cannot use it outside the channel.

To use it elsewhere, you must first close the payment channel with an on-chain transaction. Because this requires confirmation times and on-chain fees, there has been rising concern that money could be less liquid in the Lightning Network than it is on-chain.

However, this might not be the case thanks to the development of splices. In this post we explain what are splices, what is needed for them to work and how can they change our perspective on liquidity.

Submarine swaps have been in the talk for a couple of weeks and there are already some interesting implementations in products and services . But, what exactly are they and how do they work? In this post we answer these questions.

To understand submarine swaps, we first need to talk about HTLCs: hashed time-locked contracts. They are easier to understand than what it seems. And, the good thing is that understanding HTLCs is not just key to understanding submarine swaps but also the Lightning Network itself.

HTLC as building blocks

Let’s say you are a proud owner of a bitcoin and you send it to an address that belongs to your friend, Martin. To spend the bitcoin, Martin needs to prove he has the corresponding private key to that address. This is how Bitcoin works at the basic level: Martin proves he has the key and he can spend the money. …

In the last couple of weeks, many people in the Bitcoin community have been talking about inbound capacity in the Lightning Network. The increasing difficulty to receive the Lightning Torch together with Bitrefill’s launch of Thor and LND’s release of Lightning Loop have led people to become more aware of it. In this post, we explain what it is and why it originates. We also share some insights that are easy to miss at first glance.

Local and Remote Balance

The need for inbound capacity can only be understood by taking a closer look at the Lightning Network’s first building block: payment channels. …

A month ago, we posted an article sharing our experience distributing Bitcoin in the most notorious slum in Buenos Aires, Argentina. The trial and its results were very well received in the Bitcoin community, with people agreeing it would be awesome to see more of these experiments happen. The question we got asked the most was: what’s the next step? In this post we address that question.

Barrio 31 is next to the main transfer center of Buenos Aires and a few meters from its most expensive neighborhood.

In the first trial, we distributed bitcoins to 25 residents of Barrio 31. GiveCrypto provided funds that were given out in the form of donations and people conducted transactions using Muun Wallet. In this case, we view charity as a medium to build education and adoption, since it would have been very hard for participants to experience Bitcoin otherwise. …

In December 2018, we conducted a trial in the most emblematic slum in Buenos Aires, Barrio 31. The aim was to give residents donations that would both help them financially and encourage them to learn about and use Bitcoin. In this post, you can read about why we chose Barrio 31 and Muun Wallet.

For 11 days, 24 residents of the neighborhood received the equivalent of 3.5USD/day in Bitcoin. They could use it to buy food and clothes at three merchants that agreed to accept Bitcoin as a payment method. Transactions were conducted using Muun Wallet, the friendliest non-custodial wallet. …

Since Bitcoin’s creation, one of its biggest promises, has been to give access in an open financial system for people lacking the identity, banking infrastructure, literacy, numeracy or trust in their government, required to access basic banking solutions. The reason why Bitcoin still does not fulfill the bank-the-unbanked promise is simply because it isn’t ready. We need to figure out scalability, micropayments and infrastructure like wallets, ATMs and exchanges. All these are taking time, probably more time than we expected or wanted, but overcoming these barriers will determine the utility, and ultimately, the value of Bitcoin.

Bitcoin is the kind of phenomenon that is better experienced than explained. Even the earliest adopters of Bitcoin are still thrilled every time we send money to someone in another country, at 3 am, with the ease of sending an email. However, there are at least two problems with this. …
