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:

Blind Merged Mining with covenants ( sighash_anyprevout / op_ctv )

Update: the content of this gist is also explained in this Spacechains video.

This write-up was also published on bitcoin-dev.

Blind Merged Mining (BMM) is the idea of committing the hash of another blockchain into a unique location on the Bitcoin blockchain, and paying a Bitcoin fee to miners for the privilege of deciding this hash and capturing the fees inside the other blockchain. Since miners don’t have to know what the hash represents and are simply incentivized to choose the highest bidder, it requires no extra validation on their part (“blind”). This idea was originally conceived of by Paul Sztorc, but required a specific soft fork. [0]

In essence, BMM is a mechanism that allows external blockchains (altcoins, tokens) to outsource their mining to the Bitcoin blockchain. Instead of burning electricity with ASICs, th
