A blockchain is a decentralized ledger spread across multiple computers. Once a transaction is added, you can't change it without altering every block after it and getting the whole network to agree. That immutability is what makes it tamper-proof.

So what is blockchain? A blockchain is a decentralized distributed ledger that records transactions on multiple computers so that the record cannot be altered retroactively without altering all subsequent blocks and the network's consensus. So what does this mean? The easy way to describe this would be if transactions are lined up or transactions are executed on the blockchain, it makes it hard for you to go back and change what happened in the past.
