Decentralization in simple words means the division of reliable of a perticular group set up, application, or a Market structure from a person or office to many group of people's.This is related to a society like the dicision making by all members irrespective to a single members the case maybe in centralisation. Decentralization and centralisation are opposite to each other.When we talk decentralisation in a cryptocurrency world,it is the division of mastery of a token or coin by all of its users rather than one person,the creator of the token or even his group or company.Decentralisation has been achieved that time when the blockchain newtwork is operates with an rules that function with confidentiality.

We all known Bitcoin is the first cryptocurrency which was made and it spread the power to control the currency of many people and this made it more effective with the control of its value as the blockchain makes a opportunity to an individual to become a owner of his own network.

We first look on centralisation.In centralisation the all powers are on one hand. Decentralised is one of the important factor to solve all of this gives a network controlled by multiple computers where each progress it's own data from a previous block create by the other user allowing each of its end user to create it's own policy and maintaining their own privacy to safeguard.

As I am a steemitian and I share a example of decentralisation is steemit community,in which every person has power to become a whale as long as your have the right attribute to offer to people on the platform also having to group up in different communities and become moderator of the system at large.

Let's now,I share you a table about difference between Centralisation and decentralisation:

Centralisation	Decentralisation
Centralisation gives us all power to a single person	Decentralization gives us power to all its users.
In centralisation the decision making by a single user.	In decentralization system decision making by a every user.
In centralisation output has been controlled by a leader.	In decentralization output has been controlled by all users.
Centralisation is a slow process output.	Decentralization is a high and effective output.
