To explain well what this suggests, 1st i would like to create a quick clarification of what centralization is, a nation or country is governed by a president and also the public powers, this may be a centralized system, and it's centralized as a result of the facility or management of the selections within the destination of the country are created by a central entity that during this case is that the government, however, a decentralized system is that the opposite of this, during a decentralized system there's no central entity or government that controls its this whole system, the decentralized system is AN comprehensive system, all those that participate during this system have freedom of expression and participation, decentralization divides power and distributes it in such the way that choices aren't created by a central entity.

At the economic level, decentralization has come back to represent a good revolution, taking into account that the common financial set-up is delineate by the banks that are the service suppliers, so as to hold out transfers and alternative operations during this conventional system, it's the bank that authorizes and approves transactions, they need a record of client information and knowledge, these in turn are ruled by laws of the governments of the country wherever they perform their activity, this can be however in January 2009 a surprise called Bitcoin was born , the primary cryptocurrency and with it the activation of a decentralized system called BlockchainThis could be a substitution, therefore to talk, of a bank, it's a chain of blocks during which exchange operations are carried out during a quick and secure means, these operations once being valid square measure registered and can't be altered, its operation is predicated during a series of nodes connected to every alternative that are chargeable for spreading the data, every server connected to the current network becomes a brand new node, this technique represents Associate in Nursing improved different in terms of causation cash, cash will be sent from one side from the planet to the opposite during a quick, safe and direct means, from person to person, while not depending on a central entity and with low commission prices. A significant example by means that of that I will show you the decentralized system compared to the centralized one are the social networks, the simplest notable and therefore the ones we use the foremost on a daily square measure, Facebook, Twitter, Instagram, YouTube among others,

These are centralized social networks, In them, the central servers square measure people who manage the data and management all the content that's revealed in them, the service suppliers have management of the accounts and have the facility to censor some content that doesn't appear to them, a decentralized social network is one that operates on a blockchain, AN example of them is SteemitAs we already understand in Steemit we tend to all own our own accounts, here we will produce quality content without worrying of being censored , at constant time we tend to receive Associate in Nursing economic incentive for our publications, this represents a significant distinction in terms of the employment of 1 or the opposite.

In general, decentralization means that equality, participation, distribution of functions and edges, it means that future, and if this technique were enforced at a general level, existing deficiencies may be improved during a safe, clear and unalterable means.

A decentralized system as i discussed before, has several benefits compared to a centralized system, these represent an excellent improvement however even have a series of disadvantages that i'm positive that with the passage of your time they're going to be resolved, same this below i'll mention a touch of their benefits and disadvantages.

1. In a decentralized system it's characterised by being safe, quick and clear.

2. In a centralized system, all participants have constant rights to specific themselves ANd to possess an opinion concerning the selections which will be created.

3. The data and knowledge that area unit entered can not be altered or deleted by a controlling or central entity.

4. At a monetary level, if a decentralized system like a blockchain is employed, you may be ready to create transactions quickly and directly, from person to person, with low commission prices while not betting on the approval of a bank, together with international operations, except for this can be AN inclusive system, wherever anyone will produce their account while not distinction older, sex or race and in a neater means than within the standard system.

5. Regarding social networks, there's freedom of expression, you're the owner of your account therefore neither your publications nor your accounts is closed or censored .

6. The creation of quality and original content is inspired, for this the creators area unit rewarded.

1. The processes are irreversible, care should be taken once closing associate operation, as an example, if a cash transfer is created and by mistake we tend to place the incorrect recipient, we might lose the money while not the correct to assert, the sole approach would be that the one that receives it wish to come.

2. Due to its characteristics, associate anonymous identity will be maintained, that is why it's aforesaid that it will be used for concealing.

3. As there's no central entity that stores the knowledge, if we lose the access codes we tend to lose our accounts, this can be as a result of we tend to area unit the only ones WHO handle our own access data.

4. Its content and quality build its adoption slow, this makes its quality restricted.

5. In the absence of a central entity, in some cases it'd be tough to achieve agreement as a result of all participants have a voice and vote.

A decentralized blockchain will represent a big improvement in any space within which it's applied, its nice blessings can be employed in a good thanks to improve the standard of lifetime of folks, below i will be able to mention some areas within which i believe that it will be of nice profit to implement a series of blocks, what we all know as Blockckain .

Banking sector

The decentralized blockchain system helps to extend the speed of transactions through reducing time the banks ar able to operate therefore pushing their services on the far side operating hours, funds will still be sent and received on-line quicker that additionally reduces cases of felony at banks.
The decentralized system is additionally applied in storage of information and records of the various those who use the banking sector.

Health sector

Applying the decentralized system within the health sector is incredibly crucial and necessary as a result of patients' knowledge is safe and well secured. thanks to its transparency, it permits completely different physicians holmium ar operative on the patient to the current knowledge. Patients eat their hospital records and keep them and shut in they loos them, they'll return to the hospital library and check for these details as a result of they're hold on firm a few years.

Voting

During vote, the decentralized system is used to alter everybody access details on however the vote method is current thus on produce an honest follow from completely different participants. This helps in reducing cases of cheating throughout the elections.

Business sector

Big businesses apply the decentralized blockchain system due to ought to store their records safely in processed systems. The business records are hold on and unbroken regarding the daily sales created and purchases thus on produce records for referral and simple follow up.

A blockchain means that a good advance looking on the case wherever it's applied, we can see however the arrival of cryptocurrencies gave a helpful flip in terms of a way to invest and transfer cash, that's why its adoption might improve several senses of our existence, in person I believe that a stronger dissemination of knowledge relating to edges} and benefits of a decentralized system, can facilitate a quicker acceptance by society, its implementation would bring nice enhancements to the planet, thus its nice importance.
