Review what you have learned about blockchain technology in this 7-video course that illuminates the two types of Ethereum accounts—externally-owned and contract—and the data needed for each of them. Study the glossary of Ethereum terms to ensure your full understanding of such key terms as mining; ether; and smart contracts—or protocols used for digitally specifying, verifying, and enforcing a contract; and Ethereum Virtual Machines. Next, you will begin to compare and contrast the Trie data structure that represents associative arrays and its space-optimized version, the Patricia trie (or digital tree). Learn how to recognize the functions of branch and extension modes in a Merkle Patricia trie—essentially a modified version of a Patricia trie—before identifying the purpose of its leaf nodes. As a final exercise, you will be asked to list the important characteristics of the Ethereum network, and identify specific fields with an Ethereum account state.

WHAT YOU WILL LEARN

  • recall the fundamentals of blockchain technology such as the storage of records across a sequence of blocks
    define Ethereum-specific terms such as mining, ether, and smart contracts
    identify the two types of Ethereum accounts - externally owned and contract - and the data that is needed for each of them
    describe the trie data structure that is used to represent associative arrays and distinguish it from its space-optimized version, the Patricia trie
  • recognize the functions of branch and extension nodes in a Merkle Patricia trie
    identify the purpose of leaf nodes in a Merkle Patricia trie
    recall the types of nodes in a Merkle Patricia trie data structure and identify the characteristics of the Ethereum network
