This is the second lecture in the Blockchain series of lectures. In this lecture, students will be able to learn more about:

• Motives and ideas behind blocking technology,
  
• Digital assets (cryptocurrencies, tokens, smart contracts),
  
• The role and connections of cryptography and distributed systems in this technology,
  
• Properties and structure of the network,
  
• Popular consensus protocols used in these networks,
  
• Movement of transactions in the network - the working principle of blocking technology,
  
• Similarities and differences between the two most popular blockchain platforms (Bitcoin and Ethereum).
  

To make it easier to follow this lecture, it is necessary to watch the first lecture in this series, which is: Cryptography and Distributed systems.

After this lecture, next week there will be a workshop where students will be expected to implement some of the blockchain main elements, so the knowledge of at least one of the programming languages such as Python, C++, Java is strongly recommended.
