Question

A copy of the blockchain is maintained locally in all the user nodes of the network.

Answer 1

It is true.

The Blockchain is a digital data record in which the information is stored as a chain of blocks.

- Here blocks refer to the user information coded in computer language.

- Blockchains are used by bit-coins to store data.

Node

- A Node is an active electronic device, like the computer or phone which has an IP address and functions as node as long as it is connected to the internet.

- The node maintains a copy of the block-chain to support and process the block-chain.
