question 2 of 10
what is the purpose of blockchain technology?
be a secure backup for password protection on all digital accounts.
run software programs that allow mobile apps to connect to the internet.
record, store and track digital information and transactions.
make artwork that can be shared on the internet publicly.

Explanation:

Blockchain is a digital ledger technology. It records, stores, and tracks digital information and transactions in a decentralized and secure way. It is not mainly for password backup (it has security aspects but not just for that), not for running software for mobile - app internet connection (that's more about network protocols and app infrastructure), and not for making shareable artwork (though NFTs use blockchain, it's a broader technology for data/transaction management).

Answer:

Record, store and track digital information and transactions.
