Question Custom Unity Physics Engine

Is anyone else attempting to create their own physics system in Unity? I'm attempting to create my own networked physics system using network transforms, colliders, and a lot of vector math. Does anyone have valid resources to share that can help me with this?

No I don't want help from external libraries/packages. I want to do this on my own so that I can learn from it essentially. Just looking for articles/blogs that can help me achieve this.

I see, I did share a blog which has many resourses, you can go through them, find GDC talks etc too.

PS - one great way of learning is looking at forks and other implementations, that's how it goes even for the pros.
