Answer:

option of this answer is d

Answer 2

The answer is d) All of the above  

Explanation:

“A blockchain” is defined as a ‘decentralized’, ‘distributed’ and ‘public digital ledger’ which records the transactions across many computer systems so that any “involved record” cannot be modified retroactively, without the modification of all following blocks.

Blockchain, a “distributed database”, runs on several computers at the similar time. It grows constantly with new sets of recording referred as 'blocks' are added on to it. Each block compromises a timestamp with a link to the foregoing block to form the chain.
