LP-10006: Learning Path - MPC & Threshold Custody

Abstract

"Keys, custody, signing, institutions."

This path covers MPC systems from primitives to production custody.

Motivation

Threshold cryptography enables distributed custody without single points of failure. This path covers the mathematical and practical aspects of MPC systems.

Audience

Security engineers, custodians, institutional developers.

Prerequisites

Complete LP-0011: Core Protocol Path first.

Outcome

After completing this path, you will understand:

  • Threshold cryptography primitives
  • T-Chain architecture and operations
  • DKG and key resharing
  • Signer rotation and asset binding
  • HSM and KMS integration
