Curious to know what folks on here think of [Chamath’s latest tweet](https://twitter.com/chamath/status/1707088037854031916) where he explains how AI and labor are about to push corporations and their shareholders towards automation and labor reduction.

a few questions…

- what parts of this twitter thread do you agree with? 
- what parts do you disagree with?
- what role will labor play in our economy a decade from now?
- will this AI transformation meaningfully change wealth concentration?
- are there any other important second-order effects you think AI will have on the world?

Creative Destruction & The AI-Labor Paradigm

Hey Stacker Community! It's gandlaf here. 🚀

I'm thrilled to announce that I'll be hosting an Ask Me Anything (AMA) session about [PROXNUT](https://proxnut.com). PROXNUT is a Cashu proxy crafted to protect and monetize web resources, and I can't wait to delve deeper into it with you all.

📌 What's PROXNUT All About?  
At its core, PROXNUT integrates seamlessly with a Cashu, enabling users to access protected web resources using tokens. It's a bridge between content providers aiming to monetize their content and users who value it. The system works completely stateless and requires no accounts and no sign ups, and enables monetization of APIs, content and more, with privacy by default. 

📅 Date & Time: Drop your questions now! I will be answering them tomorrow from 08:00 till 11:00 AM CEST 

📍 Where: Right here on stacker.news!

Why Join the AMA?  
- Behind-the-Scenes: I'll share the inspiration behind PROXNUT and the challenges during its development.
- Direct Answers: Have questions or feedback? I'm here to address them all.
- Peek into the Future: Discover what's next for PROXNUT and how you can be a part of its journey.

How to Participate:  
1. Save the date for our AMA.
2. Think of any questions or feedback about PROXNUT.
3. Join the conversation and let's engage!

For more insights, check out the [PROXNUT website](https://proxnut.com) and our [GitHub Repository](https://github.com/gandlafbtc/proxnut).

I genuinely believe PROXNUT can redefine the way we approach web resource monetization. Whether you're a fellow developer, a content creator, or just curious, I'm eager to chat with you!

Spread the word, and let's make this AMA a knowledge-packed session! 🎉

Catch you soon,  
gandlaf

Being patient is hard.

It's hard to wait; it's frustrating, it's difficult, and it can even make us feel helpless, like we have no power over what happens next. What's the vibe of patience? Waiting in line at the doctor's office, waiting for difficult situations to change, waiting to see the results from your daily habits.

But there's a state very close to patience — one where you are still waiting for something to happen — that has a completely different emotional tone. It's the state of anticipation.

Anticipation is exciting. Something good is going to happen. There's joy just around the corner; it's going to be so wonderful when it finally arrives. You anticipate vacations, special events, and life milestones. As it turns out, research find that anticipation can sometimes be even more enjoyable than the event itself.

Here's something to try out today:

What would it look like if you waited with anticipation instead of patience?

If you were anticipating... you would be certain that good things were coming, so you'd feel excited and hopeful.

If you were anticipating... you would trust that changes were occurring, even if you couldn't see them quite yet.

If you were anticipating... you would enjoy the process of waiting rather than simply rushing to get to the end.

Wouldn't that be more so much enjoyable?

**What is CoinJoin?**
---------------------

![CoinJoin Illustration](https://imgprxy.stacker.news/n9yD-QOAityfKSmMcfTThJrAE8o1QIB2i6SuZOmVbmE/rs:fit:600:500:0/g:no/aHR0cHM6Ly9pbWFnZWRlbGl2ZXJ5Lm5ldC93eXJ3cDNjLWowZ0REVVdnbkU3bGlnLzYwOWIxNzdjLTJkOTktNDU4YS00YzNiLTYzZmVjNjgzMWQwMC9wdWJsaWM)

CoinJoin is a privacy-enhancing technique used in cryptocurrencies, primarily Bitcoin, to improve anonymity. It accomplishes this by combining multiple transactions into a single transaction, making it more challenging to trace the origin and destination of the funds involved.

**Difference between Joinstr and Other CoinJoin Implementations**

Joinstr sets itself apart from other CoinJoin implementations through several key features:

*   **No Centralized Coordinator:** Unlike some CoinJoin implementations that rely on a central coordinator, Joinstr operates in a decentralized manner, enhancing user privacy.
    
*   **Better UI/UX:** Joinstr prioritizes user experience, ensuring a smoother and more intuitive interface for participants.
    
*   **Simple Implementation:** The implementation of Joinstr is straightforward, making it accessible to a wide range of users.
    
*   **No Fidelity Bonds:** Joinstr does not require participants to lock up fidelity bonds, offering more flexibility.
    
*   **Anonymous Founder:** The project maintains a commitment to anonymity, aligning with its privacy-centric goals.
    

**How Does It Work?**
---------------------

![Joinstr Workflow](https://imgprxy.stacker.news/jhPCv7GA4FyMWUNejpwGLKV-GqcYQGH3KbTAvCqUJec/rs:fit:600:500:0/g:no/aHR0cHM6Ly9pbWFnZWRlbGl2ZXJ5Lm5ldC93eXJ3cDNjLWowZ0REVVdnbkU3bGlnLzdmYjIzNDIzLTg4NmMtNDViOS01YjhmLWNjNGMyZGFlNTYwMC9wdWJsaWM)

Joinstr operates by creating a post-mix transaction with an event ID. Here's a simplified overview of how it works:

1.  Calculate the `postmix_val` using the formula: `(input_sum - fee) / 5`.
  
2.  Generate an event ID for the CoinJoin round.
    
3.  Participants provide their UTXOs as inputs, specifying the amount and type.
    
4.  The CoinJoin transaction is created using these inputs and the event ID.
    
5.  The resulting transaction is broadcast to the blockchain.
    

**Code and Implementation Details**

Joinstr is available through various interfaces:

*   `__cli`: Command-line interface for advanced users.
    
*   `__web`: Web interface for a user-friendly experience.
    
*   `__mobile app`: A mobile application for on-the-go CoinJoin transactions.
    
*   `__electrum plugin`: Integration with the Electrum wallet for added convenience.
    

The Joinstr codebase and implementation details can be found in its repository: [Joinstr on GitLab](https://gitlab.com/1440000bytes/joinstr).

**Joinstr in Electrum** ![Joinstr in Electrum](https://imgprxy.stacker.news/KA_Y3Qiq8PRZj29kUyaSd6xWTjtFpkeWcjb3Rj2HAdI/rs:fit:600:500:0/g:no/aHR0cHM6Ly9pbWFnZWRlbGl2ZXJ5Lm5ldC93eXJ3cDNjLWowZ0REVVdnbkU3bGlnLzgyYjlkMDVkLTJlZmEtNDJiZC1kMDQwLTA0NjhhYThiMjgwMC9wdWJsaWM)

`Joinstr` also integrates seamlessly with the Electrum wallet, providing a user-friendly way to access CoinJoin functionality. An example transaction using Joinstr in Electrum can be found [here](https://sandbox.cryptpad.info/slide/inner.html?ver=5.4.1).

**Demo** ![Joinstr Demo](https://imgprxy.stacker.news/7m9hpPyWYoZ9c8ECrcGp_M_Zk_jrdKtiMEiQietVkGI/rs:fit:600:500:0/g:no/aHR0cHM6Ly9pbWFnZWRlbGl2ZXJ5Lm5ldC93eXJ3cDNjLWowZ0REVVdnbkU3bGlnLzdhZGIwMjYzLTE0MTUtNGQ0OS04YmNmLWE5ZjE5ZjY3NWQwMC9wdWJsaWM)

**What's Next?**
----------------

Joinstr continues to evolve, and the development team has an exciting roadmap ahead. Some items on their to-do list include:

*   Implementing new Tor circuits for each request to enhance privacy.
    
*   Utilizing NIP 38/48 for encrypted channels.
    
*   Allowing custom denominations for CoinJoin pools.
    
*   Restricting the registration of different types of inputs for a round.
    
*   Implementing NIP 9 to delete events after a round is completed.
    

**Using Multisig and Miniscript Policies in CoinJoin**
