I'd also prefer a C version, but I think it's possible to call a Go function from C [0]. I don't know how well that would work though, since Go requires a runtime.

There is also a Rust implementation of libp2p[0]. Exposing C functions from that library is probably the most "proper" way currently feasible to use libp2p from C.

C also requires a runtime, it just happens to be a very tiny one.
