Class Project

Pu Purpose

• Learn and analyze a distributed system from a

security (and cryptography) perspective

• Will

focus

• n

blockchain-based systems, e.g., platforms for cryptocurrencies and smart-contracts

• Learn to write a report about technical security-

relevant aspects of a system

• Learn to give a short (15min) technical talk about

technical security-relevant aspects of a system

3

Wh What you need to do

• Choose one of the selected blockchain-based (or

consensus-based) systems and cryptocurrencies and study its technical details

• Write a 7 page report (details next)
• Give a 20 minute presentation (present for 15min

and answer questions for 5min) about the system (details next)

4

Sy Syst stems that you could consider

• Bitcoin, Bitcoin Cash, and Litecoin (all together as
• ne project, two students can work together as a

team on this)

• Ethereum and Ethereum Classic (both together as
• ne project, two students can work together as a

team on this)

• Ripple (single student)
• Cardano (single student)
• NEO (single student)
• Dash (single student)

Wh What sh shou

• uld

ld yo your report co cover?

• Executive Summary: Short overview of the system and its use cases

(1 page)

• Advantages: Purpose of the system, e.g., what shortcomings of other

systems it addresses, what new features it introduces (1 page)

• Usage: Use cases for the system (1 page)
• Technical Details (4 pages)
• System architecture (P2P, centralized, or hybrid)
• Consensus approach (POW, POS, byzantine agreement/other consensus … etc.)
• Cryptographic primitives used (hash functions, encryption, signatures … etc.)
• Other special features (e.g., anonymity, smart-contracts … etc.)
