What is a blockchain database?

A blockchain has three central attributes. First, a blockchain database must be cryptographically secure. That means in order to access or add data on the database, you need two cryptographic keys: a public key, which is basically the address in the database, and the private key, which is a personal key that must be authenticated by the network.
