Briefly explain the structure of a blockchain and the main components in it and also briefly explain how the blocks are connected in a blockchain?
A structure of a blockchain is straight-forward and consists of various blocks which are bonded together using pointers and linked lists. The lists can be stored either in a text file or as a simple database. These blockchains are linked using the following main components,
Pointers: These are a kind of variable that store the location of another variable, specifically the position of the variable in the blockchain.
Linked list: A Linked list is a sequence of blocks where each block is linked to specific data, and these are linked to each other using a pointer.
The first block does not have a pointer, and the last block may have a pointer which is empty, so it has a null value. Since it is the last block, it doesn’t point anywhere or to another block.
In essence, a blockchain is a connected list of records,
