1. What do you know about blockchain?

BC is a decentralized distributed database of immutable records.

The transactions are protected by strong cryptographic algos.

Every new record is validated across the distributed network before it is stored in a block.

To access the data of the first block, you have to traverse from the last created block to the first.

2. What is the principle on which blockchain technology is based on?

BC is based on the Distributed Ledger technology which aims to provide a shared single source of truth being distributed across the network.

3. What are the different types of BCs available?

Public, Private, Consortium.

4. Why is BC a trusted approach?

BC is an immutable ledger. The transactional records are secured by strong cryptographic algos. Also, every participants have the shared single source of truth.

It distributes trust among actors in the system via an economic game that incentivize actors to cooperate with rules defined by the protocol.
