Blockchain serves as a revolutionary form of database—a unique, immutable, and tamper-proof structure. The immutability is achieved through a process of “hashing,” where data inputs are converted into coded representations of fixed length, rendering them seemingly meaningless. However, even the slightest alteration to any input will entirely change the resulting hash. These hashed data inputs are then organized into “Blocks,” with each new Block encompassing the data from the previous one, forming a continuous “Block-Chain.”

The brilliance of this design lies in its interdependence, where each Block relies on the information from the previous Block, effectively making tampering utterly impossible. Any modification to the chain will lead to a complete transformation of all subsequent outputs.

Notably, the decentralised nature of blockchain comes into play, as the ledger is duplicated across numerous servers. This decentralisation, when combined with the “Chain of Blocks,” results in an infallible method of securely holding data—a system that is both tamper-proof and 100% reliable.
