1 year ago It's a good question and something I've been thinking about as well.
Some thoughts:
- I don't think Rust would be much faster. While the rollback code is nuanced running it likely isn't a performance bottleneck.
- Porting to Rust would be great because it'd make it easier to make a version of Tangle that runs on web and native.
- Some logic / state would still have to live in JavaScript to help avoid extra copies of memory.
Initially I started writing Tangle in Rust but I was finding it easier to iterate on the architecture in TypeScript. Now that I've nailed down the key architectural details it may be easier to try again in Rust.
I should definitely study GGRS, but I'm hesitant to adopt it immediately. Tangle's designed for apps as well as games which leads to different priorities. Like this open issue would be a problem for Tangle: https://github.com/gschup/ggrs/issues/23.
But I suspect GGRS is doing some things better than Tangle to learn from.
Thanks for asking! It's got me thinking.
taking a quick look through the code, and it seems as though the code is being run through a custom rollback netcode implementation written in typescript. However, wouldn't typescript be a bit slow? It feels like it would be better to use a network library written in rust, like GGRS
