• OPEN and CLOSE
• AUTH and AUTHCALL

15. What does AUTH verify in EIP-3074?

• User identities and transactions.
• Contract addresses and fees.
• Signatures and actions.
• Token balances and states.

16. What does AUTHCALL do in EIP-3074?

• It verifies the validity of transaction receipts before processing them.
• It enables automatic gas payments for all Ethereum transactions.
• It calls the target contract(s) with the originator address as the caller rather than the message sender.
• It restricts access to wallet functions based on signature verification.

17. What is the purpose of the Dencun update on Ethereum?

• Improving energy efficiency of mining.
• Introducing new cryptocurrency tokens.

• Removing old and excess network history to simplify it.
• Introducing new smart contract standards for better security.
• Increasing the block size to enhance scalability.

• It eliminates all transaction fees on the network.
• It provides a more intuitive user experience while enhancing security.

20. What does Ethereum account abstraction bring to Ethereum accounts?

• It restricts them to basic wallet functionalities without any enhancements.
• It transforms them into dynamic “smart accounts” capable of much more than simply holding funds or executing transactions.
• It solely focuses on increasing transaction speeds without other improvements.
• It eliminates the ability to interact with smart contracts entirely.

21. What are the core challenges Ethereum faces in its journey toward mass adoption?

• Sometimes.
• Yes.
• Only for specific cases.
• No.

29. What happens when gas runs out without the transaction being complete?

• All state changes are reversed, and the used Ethereum Gas is given to the miner.
• The transaction completes with a fail state but retains the gas used.
• The transaction is permanently lost and cannot be recovered.
• All data is saved and the transaction can be completed later.

30. How does Bitcoin check the latest state compared to Ethereum?
