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

The main difference between cryptocurrencies and blockchain is that cryptocurrencies are digital currencies which use cryptography to secure and verify transactions, while a blockchain is a decentralized ledger system that records all cryptocurrency transactions. Cryptocurrencies can be used for various types of transactions including buying goods or services, transferring funds, and storing value. A blockchain is essentially an open, distributed ledger that records transactions across many computers in a secure and verifiable way.
