It's incredibly vague still, that's the problem.
Like, I see, if I wanted to roll my own shitcoin, I can't publish the source code of it on Codeberg.
But, say, a Blockchain lookup app - technically it's a cryptocurrency related project, but at the end of the day it's just an app that connects to a public API and lists data from it. Is it also banned?
Or, I make an open source smart clock, from an LED matrix and an ESP32. This smart clock can link to YouTube/Twitch/etc. for viewer count, to GitHub for project stars/forks, to currency exchanges, and one includes a crypto exchange rate tracker for displaying current mainstream coin valuations (say, the top 5 most used coins). Is this project, since it's crypto related, banned?
Or let's say I come up with something blockchain adjacent, that could be utilised for cryptocurrency use... and what if I just publish a new cryptographic approach that then gets used by a new cryptocoin that suddenly becomes famous?
Or if my project uses a cryptographic system that comes from a dependency that was broken out of a cryptocurrency project?
Where do we draw the line of "related"? What level of relationship is allowed with the world of cryptocurrency? What degree of separation is deemed appropriate?
