This post answer the question to the homework task for the steemit's Crypto academy fixed beginner's course task 4 by professor @yousafharoonkhan, with the question;

Define decentralization. Describe the advantages and disadvantages of a decentralized system. In what areas of life can a decentralized blockchain be helpful? (write in own words)

Define decentralization.

Decentralization can be defined as a structural management of any gathering, which involves the authority and decision making of the gathering been controlled by group of individuals which are members of the gathering, whether it's been a private or a government owned. Decentralization is antonimous to centerlization which is the control of an organisation by an individual or governmental body responsible for decision making in the organisation.

Decentralization in modern technology is a bed rock upon which Cryptocurrency are been made. This attribute in technology allow transaction to take place with any interference from a third-party. The blockchain which is the legar for recording all Cryptocurrency also works under the technology of a decentralized system.

Decentralization gives appropriate and equal chance to every member of been able to make a say or give their conclusion on matter to the table before Decision are been made. Whereas, a centerlized system blare just like a military regime of government where we all have to follow their decision where we love it or not and not able to use our citizens right as we love.

With crpytocurrecy, Decentralized system are far better off to the centralised ones as the blockchain of any token has it's governance been maintained by decentralisation and has gotten it's security from a decentralized system.

Difference between a centralised and a decentralized system.

Centerlized	Decentralised
Authority to make Decisions belongs only the leader of the system	Authority to make decisions are available to any member of the system
Decision making process usually take time in centralised system	decision making are usually as swift as possible to ensure appropriate actions
Co- ordination of work load is on a single individual and this will not be as effective.	Group of member come together to get work done and will produce more efficiency

Decribe advantages and disadvantages of a decentralized system.

Advantage

1. One of the major reason decentralized system are the best are because they give results in the most effective way. The time and speed requirements of these system is the most efficient.

2. All level of personnel in the system has equal chance of been a decision maker in the system and this give everybody a chance to give in their opinion on any arising matter.

3. The system also offer transparency of record of activities action and transaction of any kind to all member of the system and also kind proper and accurate records of all this event.

4. A decentralized system works with secrecy which comes in handy with Optimum security of funds. As a result of the division of authority in a decentralized system the risk of theft of mismanagement of fund is be eliminated.

Disadvantages

1. As a decentralized system is been managed by alot of member, they will be issue of Coordinating all of these members to work toward the same interest as everybody will believe his own ideas are the best.

2. The management cost incurred in a decentralized system will be much more then the cost of a centralised system. Multiple individuals awaits payment for getting a perfect work done is another issue of the decentralized system.

3. .A member of the system can easily weigh the whole process down as each and every one need to be properly informated of the knowledge required to make a qualified decision which might not be so to lower member of the system

In what areas of life can a decentralized blockchain be helpful?

1. Transparent governancy: The military regime is like a centralised system, where the citizens virtually has no say in the make up of the activities of the country and the governmental body do no give report nor do they listen to their citizens opinion or allow th to enjoy their right. But a decentralized system will allow it's citizens to pick their choose of leader and allow their to give full report of activities going on in the country which out this they are allow to take action on them and relieve them of their duties. A decentralized blockchain will help to eliminate any fraudulent act in the new government.

2. Better financial market: The decentralised blockchain will allow the elimination of the third party and all the cost incurred by them in any form of transaction. This will help to also stop all from of fraud in the financial market as proof of ownership are been established on the blockchain and it will not accept any form of double spending.

3. Social media: A decentralized blockchain system will help better in our social media interaction as it will give a platform not controlled by a centerlized system that can just fold up anytime or that can be restricted by any governmental body. The popular twitter as been banned for use in my country Nigeria, if twitter works on a decentralized blockchain this cannot be made possible.

Conclusion

In Cryptocurrency, centerlization has been quite helpful in term of trasaction fee but they do not provide the form of security decentralisation offer your assets. Decentralization of many part of our life activities will help use to live a more efficient life by getting us help to many choices that are best for us. Decentralization is the back bone of Cryptocurrency has the digital currency might not have been this successful if not for the decentralized system it is using.
