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

The student will be required to submit two assignments, a midterm and a final term, during the course. 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 utilizzare strumenti per l'analisi di reti complesse
Skills

At the end of the course, the student

  • will be able to develop a distributed application
  • will be able to analyse a complex network
Modalità di verifica delle capacità
  • Saranno effettutate delle verifiche intermedie
  • Sarà svolto un pogetto finale per la verifica della acquisizione delle capacità
Assessment criteria of skills

Two mid term assignments + a final project will assess the acquisition of the skills.

Comportamenti
  • Lo studente potrà acquisire e/o sviluppare sensibilità alle problematiche relative all'uso di criptomonete
Behaviors

Acquisition of sensibility relative to the use of cryptocurrencies.

Modalità di verifica dei comportamenti
  • Il mid term e final term dovranno essere accompagnati da brevi relazioni
Assessment criteria of behaviors

Student is required to submit a report for the mid  and for the final term

  • blockchains: de finitions
  • distributed consensus: definitions

the Bitcoin blockchains

  • Nakamoto consensus
  • Bitcoin mining mechanism
  • pseudoanonymity: traceability and mixing

the Bitcoin P2P Network
