Conoscenze

Al termine del corso, lo studente acquisirà conoscenze in merito alla progettazione di sistemi peer to peer e di sistemi basati su blockchain.
Knowledge

The student will acquire knowledge relative to the development of distributed systems, in particular of blockchain-based systems.

 
Modalità di verifica delle conoscenze

Per l'accertamento delle conoscenze saranno svolte delle due prove in itinere, un midterm ed un final term. Infine sarà svolto un progetto finale.
Assessment criteria of knowledge

 At the end of the course, the student must submit the final project. 
Capacità

Al termine del corso:

  • lo studente saprà sviluppare una applicazione distribuita
  • lo studente saprà sviluppare smart contract
  • lo studente conioscerà diversi meccanismi di consenso
Skills

At the end of the course, the student

  • will be able to develop a distributed application
  • will be able to develop a smart contract
  • will be able to understand consensus mechanisms
Modalità di verifica delle capacità

Sarà svolto un pogetto finale per la verifica della acquisizione delle capacità
Assessment criteria of skills
  • final project will assess the acquisition of the skills.

Introduction to the course

Peer to Peer 

  • Peer to Peer (P2P) systems: general concepts
  • Unstructured Overlays: Flooding, Random Walks, Epidemic Diffusion
  • Structured Overlays: Distributed Hash Tables (DHT), Routing on a DHT, IPFS

Case Studies:

  • BitTorrent as a Content Distribution Network
  • KAD implementation of the Kademlia DHT

Cryptocurrencies and Blockchains

  • basic concepts: basic cryptographic tools (digital signatures, cryptographic hash, Merkle trees.,..)
  • blockchains: definition
  • distributed consensus: definition

the Bitcoin blockchain

  • Bitcoin mining mechanism: Nakamoto consensus
  • pseudoanonymity: traceability and mixing
  • the Bitcoin P2P Network

Ethereum

  • structure of the blockchain and consensus mechanism
  • programming smart contracts with Solidity

Applications of blockchains:

  • NFT
  • supply chain
  • Self Sovereign Identity

Improving Scalability

  • Bitcoin Lightning Network
  • Interledger Protocols

Further Consensus mechanisms

  • Proof of Stake
  • Proof of Space
  • Byzantine consensus
