What exactly is BigChainDB

Question

I am trying to understand what exactly is BigChainDB and how is it used?  It is being said that it can solves the problem of scalability in blockchain. But I don't understand how does it fit in the blockchain structure.

Answer 1

Technically, BigChainDB internally uses RethinkDB as a datastore. Technically, the blockchain is stored as JSON string inside RethinkDB. BigChainDB is kind of wrapper on top of this storage which provides the needed cryptography techniques for building the blocks, parsinng the blocks and provides utility methods to access the database.
