Welcome to Module 1: Digital Signatures & Ownership

In this module, you'll learn how Bitcoin uses cryptography to prove ownership and authorize transactions without requiring a central authority.

You'll generate cryptographic keys, sign transactions, verify signatures, and test your knowledge with a challenge.

What you'll learn:

  • How private and public keys work together
  • How digital signatures prove ownership
  • Why Bitcoin doesn't need a central authority
  • How to spot invalid transactions

Why this matters:

Understanding cryptographic ownership is fundamental to Bitcoin and all cryptocurrencies. This is how you can truly "own" digital assets without relying on banks or other institutions.
