Explain the meaning of blockchain in general terms.

"I'd say that a blockchain is essentially a digital record of transactions. Each record is called a block and they are linked together into a single list that is referred to as a chain. Most commonly, blockchains are used to record cryptocurrency transactions like Bitcoin, but they can be used in other situations as well. A peer-to-peer network of computers work together to validate each transaction before it is added to the blockchain. I have several years of experience in creating secure systems that record and store blockchain data, and I look forward to continuing to gain even more experience and knowledge in this space."
