That's very acceptable execution times I would guess. Are the ts execution times much higher?
Nostringer in Typescript was fun, but did it again in a serious language this time: nostringer-rs is born, a blazing fast unlinkable ring signature scheme, written in Rust 🦀
Try it with the cli: cargo install nostringer_cli && nostringer_cli demo

Yes very acceptable!
I did not benchmark but I suspect the ts execution times would me much higher.
Btw I will add wasm compatibility for usage of the rust lib in browser and in JavaScript projects
