Chaumian cash in a Bitcoin world - cashu, Fedimint

What's this for?

• More scalable/faster than a blockchain (not enough utxos)
• Much better privacy security model than a blockchain
• Same or better theft security model than TTP but much worse than a blockchain

If it's so great, why hasn't it been done yet?

These are the steps I took to install and run a nostr relay on a new server.

First, you'll need the server, this tutorial is using the most basic server Hetzner provides (CX11 - €4.15/mo), you don't need much. If you don't know where to get your server from and decide to go with Hetzner, consider using my affiliate link: https://hetzner.cloud/?ref=4FZql6rUwaeQ

Once you have your server running, log into it via SSH. I'm on a MacOS, so I'll use Terminal as my command line tool. open a new Terminal window and paste the following commands:

#define static_assert(c) do { int _x = 1/((int)c); } while (0)

int main() {
    static_assert(sizeof(int) == 4);
    static_assert(sizeof(int) < 4);
    return 0;
}

/* output:
$ gcc t.c
