Blockchain BTA Certified Blockchain Developer - Ethereum Sample Questions:
Sending one Ether is actually internally translated:
- A. to Finney, so it will send the equivalent of 10^3 Finney.
- B. to Szabo, so it will send the equivalent of 10^6 Szabo.
- C. to Wei, so it will send the equivalent of 10^18 Wei.
Correct Answer: C 🗳️
Transactions containing the same data to create the same smart contract are:
- A. always having the same signature.
- B. having a different signature because of the nonce which changes upon every transaction.
Correct Answer: B 🗳️
Block Difficulty:
- A. increases when the time between mined blocks is below 10 seconds, while it decreases when the time is above 20 seconds.
- B. is determined by the Ethereum Committee every fortnight to reflect the average amount of transaction and it cannot be influenced by the network itself.
- C. increases when the time between mined blocks is below 20 seconds, while it decreases when the time is above 60 seconds.
Correct Answer: A 🗳️
What is the difference between ERC20 and ERC721 Tokens in simple terms?
- A. The tokens of a certain ERC20 symbol are all different, the tokens of an ERC721 symbol are all the same. So, ERC20 tokens are non-fungible while ERC721 tokens are fungible.
- B. The tokens of a certain ERC20 symbol are all the same, the tokens of an ERC721 symbol are all different. So, ERC20 tokens are fungible, while ERC721 tokens are non-fungible.
Correct Answer: B 🗳️
EVM assembly:
- A. is another language similar to LLL, more secure than Solidity.
- B. can be split across multiple files, but every contract must be in a file with the same name as the contract itself.
