Hello beautiful Steemians, I am @hadassah26 and this is my crypto week 9 homework, today I will be treating Decentralization and Centralization, and comparisons.

Decentralisation

link

When we say decentralised system it means a system with high level of equality, and there is no manipulation of any kind but the system carries or gives the same treatment to all its users and high level of privacy to its users as observed in decentralized blockchain,

Moreover, in decentralised system there is no dominance from only one user but all members have a part to play in the activities of the system no one is exempted as it happens in centralisation,which enables diversification because as many members contribute it will lead to development of new and better ways of improving the system.

Centralisation

Actually centralisation is what about 90℅ of the world population has embraced because centralised came out first before decentralised,most firms in the world are centralised including banks all the branches are connected to the main branch, In centralised the only lord here is the authority,the authority dictates whatever happens in the firm, members in the firm do not contribute and have no atom of dominion.

In centralisation there is no equality in centralized system top authority are given preferential treatment when i say preferential treatment i mean they break the rules of the system and they are being favoured just like having immunity.

Last 3 years my uncle deposited huge amount of money into a named bank in my country after some months he decided to withdraw the money for an emergency upon reaching the bank he was kind of being toyed with by the bank for one week such as bring this document, get this document for one week not knowing it was a delaying tactics played by the bank, finally we were told by the bank general manager that we should give them one more month that the money has been put to use by the bank,that they transacted a business with the government after one month the money came out,there is long level of hierarchy from top to bottom in centralisation which makes dispersion of information difficult.

Comparison between Centralisation and Decentralisation

Centralised system is not opened to everyone the user or participant entering must pass through the verification process by the center authority
but in a decentralized the participant does not need to be identified or verified by any center authority but by other branches and as in decentralized blockchain all the node must agree before a new block is added to the blockchain this is done without any verification by a central node.

There is a poor communication gap between lower level management to top level management in centralisation because of long chain of ranks, if lower level pass information it may not get to the top management but rather ends up at middle level since there are many levels before you get to top level but in decentralized there is a healthy level of communication because here everybody is considered here as one.

Lower members are just left behind in decision making which will bring down their confidence and in turn ideas or innovation lower members may have that might be of aid to the firm may fade away while in decentralisation system members are involved in decision making since every member has rights and role to perform and considered as one.

Advantages of centralisation

1.Members give their best output or performance since they want to impress top management for promotions.

2.Centralised system are simple to operate because few procedures are involved.

3.Decision making is faster since decision comes from only top or central authority and does not involve all member.

4.Every member must be verified by the central authority before you can begin any transaction which reduces fraud.

5.Non volatile, cash in bank are non volatile, volatile is the rate at which the price of an asset changes over a short period of time, high volatile assets such as cryptocurriencies prices fluctuate downwards and upwards frequenyly.

Disadvantages of centralisation
1.High fees are charged when transactions are performed on the system.

2.central authority has personal information of all its users and can tamper with it anytime.

3.If the central server or authority flops the whole nodes or department connecting to it flops too.

4.Innovation is below par here since decision are taken only by top management and not inclusive of all members so innovation here is a one way thing.

5.Members do not have hundred percent access on their account Incase of any misunderstanding thier account may be freezed or blocked as banks use to do.

Advantages of decentralisation
1.Members have full power over thier account based on they possess all the keys to thier account.

2.Data is stored on many devices or blocks which makes hacking difficult in the decentralized blockchain.

3.Innovation is on a high here since there are many sources or networks working together as one.

4.Owner of an account are the sole person that can alter thier own account and nobody else,reason is that they have access to all the keys unless they made it known to another party.

5.Every node or user in the blockchain is not dependent on any third-party or government agency before transaction is taken,but transaction is taken independent of any of these parties as compared to centralized system.

Disadvantages of decentralisation
1.Like in the crypto market crypto assets are highly volatile prices fluctuates up and down frequently that is one cannot predict cryptoassets.

2.ln decentralized blockchain nodes connecting blocks in the blockchain are unknown and as a matter of fact fraudulence activities can take place as such.

3 Decentralised blockchain is not that easy to operate and non crypto enthusiast will find it difficult to operate.

4.slow decisions because every tier or member attention needs to be seek and in the blockchain all nodes must come to a consensus (agreement) before a new block will be added.

5.There are minor disagreements.

4.Which one is better for business trading and why.
Normally in decentralized business it will enable division of labour which will boost,speed up production and expansion of many branches.which will be suitable for larger companies then centralised ones here the workload will be more on central authority because they bear everything which will lead to slow production,with this reason I will go for decentralized.

5.How do you know whether a blockchain is decentralized or not.
We are going to use the same approach professor @yousafharoonkhan taught in the class.
But here we are going to use dogecoin

Stage 1

You search for the token address of (doge coin )on google as shown in the first frame.

Stage2

Type (etherscan )on Google and paste the token address of doge coin then click the search button with your mouse on the second frame

Stage3

Now scroll beneath you will see (contract )and click with your mouse to display the third frame

Stage4

You will be directed to the 4th frame which will display codings,you now look out for function,administration and self destruct after going through the coding zone we found out that function, administration and self destruct wording were not found.
This experimentation.shows dogecoin is decentralized.

Concluding
Thanks to professor @yousafharoonkhan for impacting these great knowledge.
