For task 4 in the beginner's course of the steemit crypto academy professor @yousafharoonkhan talked about Blockchain, Decentralization and Block explorer. Here is my homework on the question 2:

Decentralization is simply the division of authoritative activity of a particular company, set up, application, society or a Market structure from a single person or office to many people. This is related to almost all aspect of life as it's related to decision making by multiple individuals instead of a single person as the case maybe in centralisation. Decentralization is the therefore the opposite of centralisation.

Decentralization in the Cryptocurrency world is the division of authority of a token or coin by all of it users rather than one person , the creator of the token or even his group or company. Decentralization is been achieved with the use of the blockchain network which operates with an algorithm that function with secrecy. The bitcoin blockchain was the first as it was the first Cryptocurrency to been made, and it spread the power to control the currency over to many people and this made it more effective with the control of its value as the blockchain offers any individual a chance to become a owner of his own network.

A centralised system seems to have been the best before we get to know about decentralisation. I can't imagine a country where it's system do not have the right to put people into power all because they do not practice democracy. A centralised network required a lot of policy from it's end user which are meant to be followed even when it's not comfortable or when these policies might even be wrong. Decentralised, the solution to 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 enduser to create it's own policy and maintaining their own privacy.

A prefect example of a decentralized system is the steemit community where everybody has access to grow in 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.

• Division of labour: output of service is been distributed to many people to bring about speed and better efficient as two head are believed to be better than one. The division of labour reduces stress and limited expection from a single person .

• Transparency: Decentralized system gives room for trust without asking for it. The system work in a way that give all user right to make policy which allows the market to pay the exact fee, proper management and teach that on safe way to run the system.

• Improved security: A decentralised system give approval of authority to a large number of user without which a hack or theft cannot occur which eliminates the risk of lost of funds, unlike the centerlized system where all of it security is in a place.

• Secrecy: A decentralised network do not reveal identity of owner or authorised personnel as a key is been used for transaction purpose.

• Management flexibility: A decentralised system can easily account for its history or past work as all the system is been made know to large user and this gives room for easy adoption of a changed work area or tool.

Disadvantages of decentralised system

• Lack of knowhow: The system gives room to any user to be a owner to give authority but most of these user are not well informed of the policy to be followed to achieve the desired output
• Cost: The cost of management will be higher when large number of people are in control unlike when a single or a company runs ownership of the whole system
• Biased and difficult management: each owner will be want to give policy that will suit their own purposes or even use authorize to over ride lower user and these might not be in line with the policy from other manager giving rise to difficulties.

• monetary system: A decentralised system would help to solve issue of banking system which is a centralised networks which gives policy on how to spend Nd even monitor money spend by end users. A typical example is how the central bank placed a policy banning it's local bank on transaction with Cryptocurrency. This policy has to been followed by all bank as they function under a centralised system, discouraging a lot of user from a new and advance method of decentralised monetary system (Cryptocurrency) because the center bank want absolute control over their users financial services and details.

• Voting: The centerlized voting system where the center Authority takes and count the vote giving results which the voter cannot confirm can be resolved by introducing decentralised system where all the user can vote with them identity unknown but the number and results. Will not be altrated as the system will count to perfection the number of votes received and member can witness has it is been received.

Centralisation has cause alot of error with the way of approach of it's system, but decentralized is here to correct then if we can adopt the system. The difference in the value of different country currency can be solve if the whole world spend crypto currency which works on the decentralized system give everybody right to be owner.
