Ether and Wei are similar to which pair of currency?

Dollars and Euros
Yen and Yuan
Dollars and Pennies
Pounds and Shillings

The correct answer is: Dollars and Pennies

Ether and Wei represent different denominations of the same underlying currency within the Ethereum blockchain ecosystem. Ether is the primary currency used in this network, while Wei is the smallest unit of Ether, similar to how a penny is a smaller denomination of a dollar. In the context of currencies, the relationship between Ether and Wei parallels the relationship between dollars and pennies. Just as there are 100 pennies in a dollar, there are 1 quintillion Wei in one Ether. This hierarchical structure of currency units—where one primary currency can be divided into smaller units—highlights the way Ether and Wei function within the Ethereum network, making it essential for transactions and smart contracts. This understanding emphasizes the importance of recognizing and using appropriate currency denominations in blockchain development, particularly when dealing with transactions or programming smart contracts in Ethereum.
