“Fundamentally, a blockchain (where Bitcoin’s transactions are stored) is a database. A database is just a collection of information,” Korth explained. “Now, we’re used to databases being things like bank databases, where you have the account ID, customer name, balance and so forth. And so, naively, you think of a blockchain as some chain of blocks of transactions, but it’s just information. What makes blockchains different from traditional databases is certain special properties that blockchains have that are derived from cryptography.”
