Sample Ethereum Developer Practice Questions
Try these questions from our free Ethereum Developer practice tests. The correct answer and an explanation follow each question.
Which is TRUE about Events?
- A. Cannot be accessible by contracts because they are stored in a side-chain or similar structure.
- B. When a contract contacts another contract, they a) Are stored on chain and provide a wonderful way to receive a return value.
- C. Are mostly employed in Solidity for debugging exceptions.
Answer: A. Cannot be accessible by contracts because they are stored in a side-chain or similar structure.
Events in Solidity are a way to log information to the blockchain, making it accessible to external applications and block explorers. While events are stored on the blockchain as part of transaction receipts, they cannot be directly accessed or read by other smart contracts. They serve as a communication mechanism for off-chain entities rather than on-chain contract interaction.
What is a state channel in Ethereum layer-2 scaling?
- A. An off-chain communication channel between parties that only settles the final state on-chain
- B. A channel between Ethereum nodes for fast block propagation
- C. A smart contract that channels funds between DeFi protocols
- D. A private blockchain that posts merkle roots to Ethereum
Answer: A. An off-chain communication channel between parties that only settles the final state on-chain
State channels allow two or more parties to exchange signed state updates off-chain, opening and closing the channel with on-chain transactions.
When developing a game like battleship poker, where you must conceal the values of your opponents,
- A. Since the information on the blockchain is public and only the call is private, only other smart contracts would be able to access it. This means that nothing can be hidden on the blockchain.
- B. With agreements outside of the company holding such principles. By doing this, we can ensure that the information flow follows a clear logic and that no one else has access to it.
- C. Using personal state variables. In this manner, only the smart contract itself and no one else can view the data.
Answer: A. Since the information on the blockchain is public and only the call is private, only other smart contracts would be able to access it. This means that nothing can be hidden on the blockchain.
All information stored on a public blockchain, including smart contract state variables and transaction data, is inherently transparent and publicly accessible to anyone. There is no mechanism to truly 'hide' data on the blockchain itself. For applications requiring hidden information, such as card games, developers must employ off-chain solutions or cryptographic techniques like commitment schemes, where only hashes are stored on-chain and actual values are revealed later.
________ authors the Etthereum white paper.
- A. Satoshi Nakamoto
- B. Gavin Wood
- C. Vitalik Buterin
- D. Elon Musk
Answer: C. Vitalik Buterin
Vitalik Buterin is widely credited as the primary author of the original Ethereum white paper. This foundational document, titled 'A Next-Generation Smart Contract and Decentralized Application Platform,' introduced the world to the concept of Ethereum and its vision for a decentralized, programmable blockchain.
