I've been reading a lot about cryptocurrencies and blockchains lately. What is the difference between them?

The main difference between cryptocurrency and blockchain is that cryptocurrency is digital or virtual currency that is not tied to any government or central bank, while blockchain technology is a decentralized database that records transactions across a network of computers, allowing for secure and efficient storage and transfer of data. Cryptocurrency relies on cryptography to ensure security and anonymity, while blockchain uses distributed ledgers to record all transactions publicly in an immutable way.
