Hello Stackers!
It's Monday so we're back doing "Meta Music Mondays" 😉.
From before the territory existed there was just one post a week in a ~meta take over. Now each month we have a different theme and bring music from that theme.
Welcome to Femmes Fatales 3!!!
I absolutely loved doing this last year so I'm bringing it back for round 3!
It's Femmes Fatales, where we celebrate women in ~Music. So let's have those ladies of the lung, the sirens of sound, our Femmes Fatales!
https://youtu.be/ya69LUa1E_w?si=cM6yCALsPpp9L3Sc
I recently got introduced to these ladies. Their music is fantastic, they're really talented musicians. They are:
Lilith: The vocalist.
Lamia: The lead guitarist.
Nixe: The bassist.
Abrahel: The drummer.
Their identity is meant to be a mystery, so let's keep it that way.
These Nuns can make Noise!!
Let's go!
Talk Music. Share Tracks. Zap Sats.

The risks associated with cryptocurrencies have recently [received attention](https://www.epochtimes.se/finansinspektionen-varnar-for-investeringar-i-krypto) in the media, where e.g. the Swedish Financial Supervisory Authority warns of the high volatility and risk of investments in crypto. Within the EU, as usual, significant efforts are being made to expand the already extensive regulatory framework. Meanwhile, in the US, there has been a marked turnaround. Even the presidential family has launched their own cryptocurrencies, resulting in criticism from [industry experts](https://efn.se/vandning-om-trump-i-kryptobranschen-befangt) .
Important perspectives, however, are conspicuous by their absence in the conversation.
Iain McGilchrist, a British psychiatrist and philosopher, has introduced the hemispheric hypothesis (a theory about how the brain's two hemispheres function). **The left hemisphere is more detail- and control-oriented, while the right hemisphere is more holistic.** A society dominated by the left hemisphere, [such as our own according to McGilchrist](https://www.youtube.com/watch?v=WYB7P-xPRsk) , "would see it as its task to control everything maximally and would have a paranoid feeling that we need to have surveillance cameras everywhere...".
During a [speech](https://x.com/CollinRugg/status/1882474184338514033) at the World Economic Forum, President Trump recently stated that conservatives complain about big banks, such as Bank of America, not allowing them to conduct business within the bank. Critics argue that the American banking system has been used [to persecute](https://x.com/TFTC21/status/1861510237485965565) political opponents, both during Obama's and Biden's terms. **Under Obama, 'Operation Chokepoint' was introduced to limit certain businesses' access to banking services.** A subcommittee in the Senate [now wants to eradicate](https://x.com/SenLummis/status/1882497148975280449) this phenomenon.
**More and more people are discovering that their money is not always under their control.** Non-profit associations and [congregations](https://www.varldenidag.se/nyheter/monster-kristna-aktorer-nekas-bli-bankkunder/833990) are not allowed to open bank accounts. Sometimes they are even thrown out as bank customers. Others may report being subjected to lengthy interrogations by the bank about what they intend to do with their money, even when they just want to transfer funds between their own accounts. **Rejected churches are met with silence**, while a bank account is (still!) necessary to fully operate in society.
When leading economists at the International Monetary Fund (IMF) argue that a cashless society can [threaten fundamental rights](https://archive.ph/fpRk0) , including property rights, when churches are refused bank accounts in what is described as "**a threat to civil society**" and when regulations still fail to combat [organised crime](https://www.epochtimes.se/Ibland-kostar-det-mer-an-det-smakar) , is it not reasonable to wonder if we are on the right path?
With cash, people can pay freely without intermediaries, which constitutes a form of financial freedom. The notes you hold in your hand are your own. **Cryptocurrencies, such as Bitcoin, offer a similar possibility**: an electronic, peer-to-peer cash system (person to person).
A society dominated by the left hemisphere results in a pathological need for control, according to McGilchrist. A more holistic perspective, taking into account the right hemisphere, would acknowledge that too much control can be detrimental, that property rights are a fundamental right, and that [financial freedom](https://www.epochtimes.se/Dags-att-prioritera-transaktionsfrihet) is a human right. Do these perspectives not deserve more attention?

There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy [article on the pros of a strategic Bitcoin reserve](https://geek.npub.pro/post/dxqkgnjplttkvetprg8ox/), I wanted to take some time to chime in on the much more fun topic of digital engagement.
Let's begin by defining a couple of things:
**Nostr** is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.
**Zap** is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what [Lightning](https://lightning.network/) or [Cashu](https://cashu.space/) are.
If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.
In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.
What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.
Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.
That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.
Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.
I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.
Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?
Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?
If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

## **Necessário**
- Um Android que você não use mais (a câmera deve estar funcionando).
- Um cartão microSD (opcional, usado apenas uma vez).
- Um dispositivo para acompanhar seus fundos (provavelmente você já tem um).
## **Algumas coisas que você precisa saber**
- O dispositivo servirá como um assinador. Qualquer movimentação só será efetuada após ser assinada por ele.
- O cartão microSD será usado para transferir o APK do Electrum e garantir que o aparelho não terá contato com outras fontes de dados externas após sua formatação. Contudo, é possível usar um cabo USB para o mesmo propósito.
- A ideia é deixar sua chave privada em um dispositivo offline, que ficará desligado em 99% do tempo. Você poderá acompanhar seus fundos em outro dispositivo conectado à internet, como seu celular ou computador pessoal.
---
## **O tutorial será dividido em dois módulos:**
- Módulo 1 - Criando uma carteira fria/assinador.
- Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.
---
## **No final, teremos:**
- Uma carteira fria que também servirá como assinador.
- Um dispositivo para acompanhar os fundos da carteira.
---
## **Módulo 1 - Criando uma carteira fria/assinador**
1. Baixe o APK do Electrum na aba de **downloads** em <https://electrum.org/>. Fique à vontade para [verificar as assinaturas](https://electrum.readthedocs.io/en/latest/gpg-check.html) do software, garantindo sua autenticidade.
2. Formate o cartão microSD e coloque o APK do Electrum nele. Caso não tenha um cartão microSD, pule este passo.
3. Retire os chips e acessórios do aparelho que será usado como assinador, formate-o e aguarde a inicialização.
4. Durante a inicialização, pule a etapa de conexão ao Wi-Fi e rejeite todas as solicitações de conexão. Após isso, você pode desinstalar aplicativos desnecessários, pois precisará apenas do Electrum. Certifique-se de que Wi-Fi, Bluetooth e dados móveis estejam desligados. Você também pode ativar o **modo avião**.\
*(Curiosidade: algumas pessoas optam por abrir o aparelho e danificar a antena do Wi-Fi/Bluetooth, impossibilitando essas funcionalidades.)*
5. Insira o cartão microSD com o APK do Electrum no dispositivo e instale-o. Será necessário permitir instalações de fontes não oficiais.
6. No Electrum, crie uma carteira padrão e gere suas palavras-chave (seed). Anote-as em um local seguro. Caso algo aconteça com seu assinador, essas palavras permitirão o acesso aos seus fundos novamente. *(Aqui entra seu método pessoal de backup.)*
---
## **Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.**
1. Criar uma carteira **somente leitura** em outro dispositivo, como seu celular ou computador pessoal, é uma etapa bastante simples. Para este tutorial, usaremos outro smartphone Android com Electrum. Instale o Electrum a partir da aba de downloads em <https://electrum.org/> ou da própria Play Store. *(ATENÇÃO: O Electrum não existe oficialmente para iPhone. Desconfie se encontrar algum.)*
2. Após instalar o Electrum, crie uma carteira padrão, mas desta vez escolha a opção **Usar uma chave mestra**.
3. Agora, no assinador que criamos no primeiro módulo, exporte sua chave pública: vá em **Carteira > Detalhes da carteira > Compartilhar chave mestra pública**.
4. Escaneie o QR gerado da chave pública com o dispositivo de consulta. Assim, ele poderá acompanhar seus fundos, mas sem permissão para movimentá-los.
5. Para receber fundos, envie Bitcoin para um dos endereços gerados pela sua carteira: **Carteira > Addresses/Coins**.
6. Para movimentar fundos, crie uma transação no dispositivo de consulta. Como ele não possui a chave privada, será necessário assiná-la com o dispositivo assinador.
7. No assinador, escaneie a transação não assinada, confirme os detalhes, assine e compartilhe. Será gerado outro QR, desta vez com a transação já assinada.
8. No dispositivo de consulta, escaneie o QR da transação assinada e transmita-a para a rede.
---
## **Conclusão**
**Pontos positivos do setup:**
- **Simplicidade:** Basta um dispositivo Android antigo.
- **Flexibilidade:** Funciona como uma ótima carteira fria, ideal para holders.
**Pontos negativos do setup:**
- **Padronização:** Não utiliza seeds no padrão BIP-39, você sempre precisará usar o electrum.
- **Interface:** A aparência do Electrum pode parecer antiquada para alguns usuários.
Nesse ponto, temos uma carteira fria que também serve para assinar transações. O fluxo de assinar uma transação se torna: ***Gerar uma transação não assinada > Escanear o QR da transação não assinada > Conferir e assinar essa transação com o assinador > Gerar QR da transação assinada > Escanear a transação assinada com qualquer outro dispositivo que possa transmiti-la para a rede.***
Como alguns devem saber, uma transação assinada de Bitcoin é praticamente impossível de ser fraudada. Em um cenário catastrófico, você pode mesmo que sem internet, repassar essa transação assinada para alguém que tenha acesso à rede por qualquer meio de comunicação. Mesmo que não queiramos que isso aconteça um dia, esse setup acaba por tornar essa prática possível.
