Certified Blockchain Solutions Architect (CBSA) — Question 7

You are trying to generate a random number in Ethereum blockchain. What is the best way?

Answer options

• A. Wikipedia
• B. Coindesk
• C. Coinbase
• D. Randao
• E. ERC20

Correct answer: D

Explanation

Randao is specifically designed for generating verifiable random numbers on the Ethereum blockchain, making it the best option. The other choices, such as Wikipedia, Coindesk, and Coinbase, are not relevant tools for random number generation, while ERC20 is a standard for token creation rather than a random number generator.
