Mixnets are cool! So I built a Bitcoin transaction broadcaster that runs in the browser and sends the transaction anonymously via the @nprofile…hhad mixnet 😎

I originally had the idea for the @nprofile…5flv privacy edition hackathon, but couldn't build it myself since I was a judge. So I just decided to build it anyway 😂
Still super early and I will keep tinkering on it, but if you are curious: https://github.com/elsirion/broadnym
The stack is:
* Rust, obviously
* Leptos for the frontend
* Tailwind for some styling
* Nym for client-server comms
* Axum for the nym address server

Good point, once it's more prod ready we'll cut proper releases. For now you can check the latest commit hash (in red circle) and us the one with that in its name.

We got docker setup instructions, but note that Iroh support is still experimental and we are awaiting one last breaking protocol change from their end before we can stabilize. Also, wallet apps will have to update to the latest release to support it, for now only the CLI client can connect to Iroh federations (covered in the docs).

Outbox is a great model! Basically Mastodon, but you can easily migrate your account because it's just a private key with a lightly coupled "home relay".
How does it deal with threads? I guess my home relay has to keep track of replies to my posts? Spam will be an interesting problem to solve since suddenly my relay has to accept third party data. Maybe micro payments are the way to go?
I guess there will also be "index relays" eventually that keep the entire global routing table (which would be in the 10s of GB once nostr is successful)?

On why I think protocols ought to be designed carefully from the beginning (in particular re scalability) if we want to preserve certain properties like decentralization in the success case:

Protocols != Businesses
A business that has lots of demand can buy its way out by raising money and directing lots of resources towards solving the problem. It also has the benefit of typically controlling all the infrastructure, so is able to replace the entire underlying stack.
A protocol cannot do that, it's dependent on volunteers, grants or companies that, often against their commercial interest, keep improving it in a mostly backwards compatible way. The amount of resource that can be mobilized is smaller and the upgrade process harder (a whole ecosystem has to move).
The most likely outcome imo is that companies will build very sophisticated scaling technology, that will likely not be open source so they can have a moat, and then dominate the end user market. Us nerds can still use the core protocol, but might not even be able to communicate with the majority of users.
E-mail is a cautionary tale, try hosting your own and still reaching gmail users reliably. Or try getting ICS files for flight bookings, airlines just set the google calendar metadata since ~everyone uses GMail+GCal. It's a bit different since the centralizing force for e-mail was spam and not scaling, but I think it's a close enough analogy.
Or look at the web stack, it historically evolved to become such a bloated monstrosity (because the inventors designed a document standard and we shoehorned it into becoming an application framework) that these days only companies with millions to burn can keep up with maintaining browser engines (and Google pretty much defines the direction of travel because Chrome is number one).
So when I worry about scalability it is out of a deep care for decentralization and not seeing all that energy invested go to waste by ultimately ending up in the same place we started at. If we don't consider decentralized scaling from the beginning, the non-ideological VCs pouring money in once it gets traction certainly won't.

Keine Ahnung was für ein Wahnsinn in Deutschland wieder los ist, aber der Vorteil von Wärmetauscher basierten Systemen ist, dass sie (zumindest theoretisch, also Augen auf beim Kauf) auch umgekehrt zum kühlen im Sommer genutzt werden können. Da höre ich gewisse Kreise schon jammern 😄

Trying to pump up the Nostr engagement numbers? 😜
More seriously, if rust tells you you are doing something wrong it's typically correct about it. Not great for random hacking around without a plan, but awesome for building and maintaining reliable systems. The main problem I feel is finding good developers (that aren't already working on something super awesome).

Looking at BIPs: for small numbers just put them into the markdown spec doc, for big numbers/large vectors add a file of appropriate encoding (here a list of json and info on if its valid or what is wring with it I guess) and reference it. Not sure about specifics, not an expert in speccing, just a consumer of specs.

Do you happen to know why it begins downloading stuff like mad and supposedly runs out of memory eventually (rather quickly on a GBit backed WiFi)?

Idk why, but viewing your profile made Amethyst crash more than once for me 😬 maybe related?

One of the most important but likely most underrated things happening in Nostr right now. Building distributed systems is hard. #[0] https://github.com/nostr-protocol/nips/pull/355/files

That could hide unintentional implementation or configuration errors 😬 better to be explicitly about where money goes.

Having test vectors people can easily test against and maybe a more machine readable spec (e.g. JSON schema) would help with that. My experience with Nostr and LNURL has been one of reverse-engineering and trying to understand the author's intentions so far (human language sucks for specs).
There's only so much time people spend on spec compliance if it works(tm), being compliant should be the easiest path to "it works".

Is there a NIP for LaTeX math support? 🤪

For that it works surprisingly well 😅 also, I don't get the md hate, super easy to support in nearly any language and not too bad to read without rendering (unlike LaTeX).

Do any nostr clients support rudimentary markdown like:
* Lists
* *italic* and **bold** typefaces
* [Hyperlinks](https://bitcoin.org)
* `innline code`
```rust
// Code blocks
let foo = "bar";
```
## Subheadings
And finally footnotes [^1]
[^1]: lmk if anything works :)

Props to #[0] for being the only org I've seen so far generating their `.well-known/nostr.json` on the fly using the `?name=…` parameter and not just listing everyone with a NIP-5 handle under the domain.
Is there some open source server for that? Not that it'd be hard to implement, but why re-invent the wheel …

If it ever becomes significant I'll probably turn it off again. Kinda sad, becauseits *is* a lot of fun throwing around sats and seeing others doing so 🥲

Every day I'm amazed how such an under-engineered protocol can work so well in practice and just keeps getting better 🤯
The extensibility and scriptability (you can sign a message with a key? => you can post!) makes it even more exciting!

2023-03-11 19:53:06 UTC

Did anyone think about that leaving cryptographic evidence of having received money, in form of zap notes signed by the *recipient*, isn't the best idea re taxes 😬
If you are receiving significant amounts might be worth reconsidering.

Plugins are awesome!
They allow following the Unix philosophy of tools doing one thing and doing it well and then composing these tools to accomplish specific taksks.

After some more hacking with #[0] I finally got Zaps to work properly with my Core Lightning node. All you need is two plugins:
* clnurl: LNURL server with Nostr support https://github.com/elsirion/clnurl
* cln-zapper: Broadcast zap notes when invoices are paid https://github.com/thesimplekid/cln-zapper-rs

The results are in, it takes ~170 lines of #rustlang code and half a day of work if you implement a LNURL server for Core Lightning. Deployment was a ~25 line diff to my nix-bitcoin config.
I think #[1] nerd-sniped me 😅
Added benefit: now I can zap around on nostr like all the cool kids 😁

The thing is we can't really do anything effective against it, especially not in an ethically consistent manner as Andrew puts it quite well, so all the outrage seems not really helpful.
