The first major difference between a relational database vs blockchain technology is that they have different authoritative systems. In a relational database system, there is always a form of centralized authority. … On the other hand, blockchain technology offers a decentralized authority.

Why is Blockchain better than a database?

By storing blocks of information that are identical across its network, the blockchain cannot be controlled by a single entity and has no single point of failure. Because every node process every transaction, no individual node is crucial to the database as a whole. This makes the blockchain very durable.

Where is Blockchain data stored?

Blockchain is decentralized and hence there is no central place for it to be stored. That’s why it is stored in computers or systems all across the network. These systems or computers are known as nodes. Each of the nodes has one copy of the blockchain or in other words, the transactions that are done on the network.
