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

The main difference between cryptocurrencies and blockchain technology is that cryptocurrencies are digital currencies that use cryptography to secure and verify transactions, while blockchain technology is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value. Cryptocurrencies are decentralized and therefore not controlled by any government or central bank, whereas blockchain technology is centralized and managed by a network of computers.
