Anatomy of a Transaction

Goal 1.0

Goal 1.1

    • Solution

Goal 2.0

Goal 3.0

  • Read about Infura
  • Difference between read and write calls on the blockchain
  • Where does the read call’s computation take place?

Brownie

  • Make a ERC 20 token contract
  • Deploy it on the Ganache
  • Write a Python script using brownie to make 100 random transfers for the token
  • Print the list of all those transfers in a CSV

Events and Logs

  • Understanding Events and Logs
  • How to read them with external code, like Python or JS scripts
  • Task:
    • Pick any popular ERC 20 token deployed on Ethereum
    • Write a script which fetches all the Transfer events from that token
    • From those transfer events deduce the number of token holders, compare this number with the one stated on websites like coingecko
    • Token Holders are addresses that currently have non-zero quantity of that token, if they held the token sometime in the past they will not be counted in this.
