Just finished coding up my latest venture, [questforsats.com](https://questforsats.com). Basically what the title says - a bitcoin treasure hunt of sorts. Hide some sats somewhere fun for other stackers to find. Or go and find some that have already been placed. No creepy alleyways, you lovable incels.

You'll probably find there's none been placed yet as you're the first to see this and there might be some glitches along the way. But I'd be buzzing if you'd help me test it out and go hide some sats today.

Hey, we just wanted to update you, that we've added in-house app to Alby Hub v1.13 - **ZapPlanner**

It simply sends regular payments from your NWC wallet to a given lightning address. Not a rocket science, but there is not that many solutions yet that enable recurring donations, subscriptions, etc.

#### What We Know So Far About Silent Payments? ####

A Step Towards Enhanced Transaction Privacy in Bitcoin 

Bitcoin Silent Payments, also known as BIP352[^1], is a proposed improvement to Bitcoin’s payment system that has been gaining traction for its potential to bolster transaction privacy in Layer 1. 

###### In simple terms, Silent Payments enables users to: #####
- Generate a single, reusable static address for receiving payments, as a business this is a game changer since it make it possible to proceed with the proper financial operational security (OpSec).

- Send and receive bitcoins without disclosing transaction details to third parties, such as the person or business you pay to, cybercriminals and chain analysis companies that sell that data to anyone willing to pay for it, that will include cybercriminals or simply; if you are a business; your competitors… When you use Silent Payments, only the sender and the receiver can connect it checking the on chain activity.

- Without Silent Payments, if you are a non profit organization, public fund raiser, independent journalist, or business you needed support to setup a proper infrastructure to handle the donations or payments in a private manner. With Silent Payments, you post in your web site a single address in text format or as a QR code to receive donations or payments for goods, that simple. 

#### Can I Use Silent Payments Already? ####

Yes, but it is currently only available through select wallets that have implemented the feature. Users must have compatible wallets and ensure that both parties involved in the transaction have Silent Payments enabled. Currently, leading wallets like Blue Wallet, and others like Cake Wallet and BitBox has adopted the feature. It's essential to verify compatibility before making transactions.

Current wallets known to support it as of writing this article:

- [BlueWallet](https://bluewallet.io/)  -- Only for sending
- [Cake Wallet](https://cakewallet.com/) -- Send, receive, Privacy Preserving Scanning
- [Silentium](https://app.silentium.dev/) -- Proof of concept, good for testing
- [BitBox](https://bitbox.swiss/) -- Only for sending

#### Summarizing: ####

#### PROS: ####
- Enhanced Privacy
- Increased Security
- Improved User Experience
- Cheap and seamless implementation for non profit organization, fund raisers and businesses alike.

#### CONS: ####
- None

#### Final Thoughts ####

As Bitcoin continues to evolve, Silent Payments will play a significant role in enhancing transaction privacy and security. The potential benefits are undeniable and substantial.

In the near future, we can expect wider adoption and implementation of Silent Payments as more wallets and exchanges embrace this groundbreaking feature. Looking forward to see [Phoenix](https://phoenix.acinq.co/), [Sparrow](https://sparrowwallet.com/), [Ashigaru](https://ashigaru.rs/)[^2] and [Electrum](https://electrum.org/) adoption.

I will suggest all of us start contacting in all social networks the wallets we us and encourage them to implement Silent Payments

Here the contact info for some of them:

- Phoenix: https://twitter.com/PhoenixWallet
- Ashigaru: contact@ashigaru.rs (if you want a response, send your email signed with PGP)
- Sparrow Wallet: https://twitter.com/SparrowWallet, https://t.me/SparrowWallet
- Electrum: https://twitter.com/ElectrumWallet

[^1]: Here the link to the BIP352: https://bips.dev/352/
[^2]: Ashigaru is a fork of Samurai Wallet performed by anonymous developers (IMO, all Bitcoin related development should be anonymous, to protect the project from nefarious players, unfortunately, most developers in the arena choose to be “public” figures, hence, becoming a target of current and potential Bitcoin enemies and a weak link for the ecosystem)
[Ashigaru](https://military-history.fandom.com/wiki/Ashigaru) in Japanese means “light feet” (translated as foot soldiers or peasants)

Bitcoin Silent Payments, a step in the right direction

- [Personal website](https://marco.barulli.it): Built using [Npub.pro](https://npub.pro), it aggregates long-form articles published with [Highlighter](https://highlighter.com).
- [Contact page](https://mbarulli.github.io): While still hosted on Github, it now embeds a contact form created with [Formstr](https://formstr.app), an amazing Nostr-based form builder service
- X/Twitter, Facebbok, and LinkedIn: I've pinned posts announcing Nostr as my new home. **This is also my advice to you: don't just delete your existing social media accounts, keep them active to direct your audience to Nostr.**

Nostr prompted me to redesign my entire online presence

I would like to keep track of my bitcoin history and was wondering what people do? Is there an app that gathers what you bought and at what price at and keeps up with what you have? Or is it basically spreadsheet ninja time?

I basically want to log my purchases and keep up with how many dollars I've invested. Then I want to see it's value today. But of course every time I buy, it's at a different price, so a tool that's sorts all this would be so cool.

# Ecash on Bitcoin Educational Resources

*Most of the resource pages for ecash haven't been updated in a while (probably because the people who made them are too busy building amazing things) so here's my attempt to assemble a list of educational resources for learning about ecash. Please let me know in the comments about any articles or resources that I've missed. I'm particularly interested in adding some long-form critiques of ecash on bitcoin.*

I've been trying to learn about ecash implementations on bitcoin and have come across a lot of useful resources. Here is a post where I'm assembling them all in one place in case anyone else would like to check them out. I've listed most of the articles and podcasts by date (most recent first) so you can follow the evolution of discourse on the topic.

# Protocols

1. [Fedimint](https://fedimint.org/) is an implementation of ecash on Bitcoin where the mint is operated by a federation of guardians. You can get new coins from a fedimint by sending bitcoin to an address controlled by the federation or by paying a lightning invoice at a lightning node that is willing to talk to the mint for you. **If you are interested in trying it out, some popular wallets using fedimints are [Mutiny](https://www.mutinywallet.com/) and [Fedi (signet)](https://www.fedi.xyz/builders).**

2. [Cashu](https://cashu.space/) is an implementation of ecash on the Lightning Network where the mint is a Lightning node and you can mint new tokens by paying a lightning invoice. **If you are interested in trying it out, some popular wallets using Cashu mints are [Nutstash](https://nutstash.app/), [Minibits](https://www.minibits.cash/), and [eNuts](https://www.enuts.cash/).**

It's pretty simple. Each of these steps is done on a VM in my QubesOS install. But you could do it on any Linux box too. I'm sure I'm not the only person doing this. It's an obvious enough idea. But you should too if you're technical.

1. [Download Wasabi Wallet](https://wasabiwallet.io/)
2. Set the coordinator. I use https://btcpay.kruw.io/plugins/wabisabi-coordinator/
3. Mix my coins.
4. Install LND (you could probably use CLN for this too).
5. Install Tor and/or a VPN.
6. Configure LND to use tor in `~/.lnd/lnd.conf`
7. Deposit a mixed UTXO from Wasabi into LND with `lncli newaddress`. You can pick a specific UTXO in Wasabi by typing Crtl-C-D. Picking a specific UTXO is better for privacy, and more effficient.
8. Find a LN node to open a channel too. There's a few strategies here. One interesting one is to pick *new* Lightning nodes, eg from https://1ml.com/node?order=newest as the new nodes are most likely to be small and eventually shutdown again.
9. Open a *private* channel to that new node, using all the funds, with `lncli openchannel --private --fundmax`, and send all the funds on it to a different LN node/LN wallet. I like Phoenix myself as it's easy to run it on my phone without needing a node. Cashu wallets are good too.
10. Close the channel with `lncli closechannel --delivery_addr <addr>` That option sends all the funds remaining in the channel to the address of your choosing. Depending on how much is left I either send it back to my Wasabi wallet. Or I donate it to a charity accepting on-chain donations. The reserve amount in a LN channel is like 1%, and sending 1% to charity is fine by me! My church suggests donating 10% after all.
11. Delete everything in `~/.lnd` other than `lnd.conf`, and go back to step #7. This is important, as it resets the LN node ID for the next new channel so you can't correlate each channel being created.

Why do I do this? Because I'm getting the privacy benefits of Coinjoin. **Plus** I'm getting the privacy benefits of Lightning. Between the two, I've completely unlinked the source of my funds, and where they go, using both coinjoin to add privacy, and the inherent privacy of Lightning payments through obscure anon nodes.

This does cost a bit. But I'm happy to pay random pleb nodes channel fees to do all this. And I'm sure some of them benefit from getting free incoming capacity. The only issue is I want more people to do this too to get a bigger k-anonymity set of people doing this. Thus I'm writing this post, and boosting it too.

Happy stacking!

Oracolo is a minimalist blog powered by [Nostr](https://njump.me), that consists of a single html file, weighing only ~140Kb.
You can use whatever Nostr client that supports long format ([habla.news](https://habla.news), [yakihonne](https://yakihonne.com), [highlighter.com](https://highlighter.com), etc) to write your posts, and your personal blog is automatically updated.  
It works also without a web server; for example you can send it via email as a business card.

Take it as a didactic experiment, it's no production ready, indeed it has some limitations (no SEO friendly structure), but can work as a temporary solution (e.g. coming soon and parking pages), and it is still an example of how easy it is to create a Nostr-powered blog and deploy it on a low-tech infrastructure.

Comments and suggestions on how to improve it are welcome!

Sweet spot is definitely low(ish) level stuff in C/C++ (interested in dabbling into Rust, Zig and Odin). I work for a software service company, so unfortunately my 9/5 is generally catered towards mainstream, writing Swift for iOS, Kotlin for Android, some JS web dev... it depends on the project. A recent project was a CLI in Go which was pretty cool, and we have an upcoming one for Linux drivers, so I always look forward to those since they're more aligned with what I actually enjoy writing.

Hopefully one day I can start working on some BTC-related projects, I just haven't found the time to get into a side hustle like that yet
