Info: https://wiki.polkadot.network/en/latest/polkadot/learn/cryptography/ https://en.wikipedia.org/wiki/Schnorr_signature

Polkadot uses sr25519 as its default signing scheme, which is custom to substrate and has only been implemented in rust. The scheme is Schnorr signatures over curve25519.

we are gonna use cgo to import this https://github.com/Warchant/sr25519-crust these are c bindings for the original rust implementation https://github.com/w3f/schnorrkel

We have implementations of

Merlin and Ristretto255 in native golang

https://github.com/gtank/merlin

https://github.com/gtank/ristretto255

This make implementing sr25519 fairly trivial
