Lesson 1.3: Hashing & Digital Signatures

Welcome to Lesson 1.3! In this lesson, you'll learn about hashing and digital signatures, two fundamental cryptography concepts required to code with Plutus.

Learning Objectives

After completing this lesson, you'll be able to:

• Illustrate how hashing works.

• Describe what a digital signature is.

• Explain digital signatures use private and public keys.

• Identify the benefits of using hashing and digital signatures in Cardano.

Additional Resources

To learn more about the topics covered in this lesson, we encourage you to review the following resources:

• How Does the Blockchain Use Hashes?

• Why Cardano: Signatures

• Edwards-curve Digital Signature Algorithm (EdDSA)

Collaborate with the Pioneers Community

Remember that you can interact with the participants of the PPP through the IOG's technical community on Discord by joining the channels under the Plutus Pioneers category.

If during the program you have questions about Plutus, we invite you to share them at Cardano Stack Exchange (CSE) by adding the plutus-pioneer-program tag to your question. The IOG's Education Team members will monitor these questions to support your learning journey. Whenever you share a question at CSE, you're helping to build up the Cardano and Plutus development knowledge base.
