What problem does the "double-spending" issue solve for in cryptocurrencies, and how does blockchain address it?

Correct! Well done.

Incorrect.

The correct answer is A) It prevents the same digital funds from being spent more than once, by having the network reach consensus on a single, ordered transaction history

A

Correct Answer

It prevents the same digital funds from being spent more than once, by having the network reach consensus on a single, ordered transaction history

Explanation

Without a central authority, digital tokens could theoretically be copied and spent multiple times; consensus mechanisms ensure all nodes agree on one canonical, ordered ledger preventing this.
