Complete Go Environment Setup for TSS Coordinator (MPC) with gRPC & Barbican

A step-by-step, production-ready guide to installing Go, configuring dependencies, and setting up a secure TSS (Threshold Signature Scheme) Coordinator using MPC, gRPC, and Barbican.

What Is This Task About?

This task focuses on setting up a Go-based backend environment required to build and run a TSS Coordinator and MPC Nodes. The setup ensures compatibility between multiple cryptographic libraries, enables secure inter-service communication using gRPC, and integrates Barbican for secrets and key management.

This is a critical foundation step for systems dealing with:

• Cryptographic signing
• Distributed key generation
• Secure wallet infrastructure
• Blockchain or financial-grade security platforms

Goal of This Setup

The primary goals are:

• ✅ Install a stable and verified Go runtime
• ✅ Configure all core and cryptographic dependencies
• ✅ Enable MPC & TSS coordination
