Q&A

These were sets of questions I first asked myself and after which to a reasonable degree am able to find and understand their answers. Those who have worked on Smartcards can relate what a nonce is to the sequence counter I documented here.

  • When a smart contract is deployed, describe how the address of the smart contract is derived?
  • How does a wallet cancel a pending transaction?
  • Describe the two gas limits
  • Describe the two kinds of accounts
  • What is the purpose of the init field in a transaction
  • How can you tell if a transaction is a smart contract deployment?
  • What are the 3 major pieces inside a block?
  • What is the hashing type used in Ethereum?
  • What is the asymmetric cryptography type used in Ethereum?
  • Describe the true (unsolved computer science problem) purpose of a gas?
  • What are the kinds of rewards that a miner receives when it successfully mines a block?
  • Explain something about EIP-1559
  • How many bytes in an Ethereum account private key?
  • Describe how an account address is derived from a private key
  • Can a smart contract, by itself, create and sign a transaction?
  • How many types of nonce exist in Ethereum?
  • At what block number was EIP-1559 activated?
