OVERVIEW

This course will explore the fundamentals of blockchains, their cryptographic principles, smart contracts, and some frameworks introduced to help developers building decentralized applications in the Web3 ecosystem.

AIMS AND CONTENT

LEARNING OUTCOMES

Can a fully decentralized system be sustainable? We will study the techniques and problems related to systems based on permissioned and permissionless blockchains, and decentralized systems in general, examining with particular attention the aspects related to security.

AIMS AND LEARNING OUTCOMES

At the end of the course, students will be able to:

DISCUSS decentralized consensus algorithms and their use in peer-to-peer networks
EXPLAIN how cryptographic techniques guarantee the security of distributed ledgers
ANALYSE basic scalability issues in blockchain architectures and DESCRIBE some solutions proposed in the literature
DISCUSS some security and privacy issues in blockchain architectures and their countermeasure
IMPLEMENT basic smart contracts interacting with programmable blockchains (e.g., Ethereum, Solana)
USE available tools and libraries to interact with deployed smart contracts
UNDERSTAND basic economic, ethical and environmental problems behind blockchain platforms

PREREQUISITES

To be successful in this course, students should have basic knowledge on:

  • Computer networks
  • Distributed systems
  • Programming (JavaScript, Python)

TEACHING METHODS

This course includes lectures, practical exercises, and self-study at home.
