Formalise and implement zero-knowledge proof Σ-protocol

Σ-protocols are mature and widely-used cryptographic protocols used for digital signatures and for zero-knowledge proofs. This project is centered around their standardization and the development of a comprehensive specification and reference implementation.

The main goal is to create a detailed and accessible specification for Σ-protocols and the Fiat-Shamir heuristic, to be presented in formats like HTML or PDF, along with a reference implementation. This effort aims to make these technologies understandable and usable by a broad audience, including developers, practitioners, students, and engineers. The end goal is to make this technology more accessible for privacy-preserving applications and non-cryptographers.
