Hello my Steemit people, today I am very happy to participate again in these great #SteemitCryptoAcademy contests and although my mother tongue is Spanish, I will be doing my best to perform to the letter all the assigned tasks, I congratulate @yousafharoonkhan for his incursion as our teacher, and for his masterful class of this first week, here I share everything I understood from this first lesson, I hope I did it well and it is to your liking.

Since I joined Steemit I can say that I did not know anything about the word decentralization, now that I see this class I can gladly say what that word means to me, decentralization is the art of freedom that users have is a system, where the power to exercise a decision is distributed in the different users that make up the blockchain. A decentralized system is presented with an autonomous character, which allows its users to be owners of their own actions, without being controlled by any entity or higher authority.

Centralization on the contrary, is regulated by a higher authority to which everyone must be accountable or follow their orders and guidelines, so they are not considered independent in the decision-making process, it does not work under a democratic basis, but all users must be governed by its rules and guidelines, such as banks, for example.

Example of decentralization

Suppose there is a country with a decentralized government, which allows all its states to be owners and autonomous in all processes where they must make decisions, but these states are not in the obligation to consult or be governed by the rules of the general staff, but they are owners of these decisions and no one should question their choices, because there is this freedom among the users of this country, each one manages a system of free and independent government and the power of decision is distributed among its citizens.

Example of centralization

In ancient times where everything was governed by the orders of a king or monarch, it can be said that the centralized system was managed, where all the states of the nation belonged to that ruler called king, and had to account for all his decisions, every order that this king dictated had to be fulfilled or else had to receive a punishment for non-compliance. So the only one who exercised power without any restrictions was the ruling king at that time.

Making a comparison of a decentralized system to a centralized one, is that as we have learned to understand a little more this wonderful world of blockchain, we now know that the information of our data is handled through many servers that are interconnected with each other, meaning that the information is always going to be kept in that blockchain and there is no way or way that someone can enter and alter our data from the database. Unlike a centralized system on the blockchain that is always going to be managed through a single server, where any hacker can enter and alter the entire database as they see fit.

Sales of the decentralized system

1. Autonomy, you can manage your own resources and make the decision what to do with them, without being accountable to third parties.

2. Security, although there are always potential risks in any computer system, it can be said that the blockchain gives us security because of the way all the information is handled, as mentioned above our data is stored in a ledger where all the records of our transactions are located on the server and can not be manipulated by people with bad intentions.

3. Speed, the blockchain allows us to perform our operations in a very fast way and in a matter of seconds, because we do not have to wait for the authorization of a third party.

4. Exchange, the decentralized system allows us to perform various exchanges between our cryptocurrencies in an easy and secure way.

5. Transparency, to be able to enjoy complete sincerity regarding all our monetary operations, because the block system allows us to have the visibility to see where all our money goes or what we do with it, in this system nothing is hidden, each user has the power to see all transactions in the block chain and what is done with each cryptocurrency.

Advantages of the centralized system

1. A single server where you can have a single point of control in case of any inconvenience, it reduces the risk when solving a computer problem, because there is a single access to the information and a single authority.

2. Adaptability to changes, as it is managed through a single authority it is easy to make changes to the entire system at times of a new development and everyone has to abide by these guidelines.

3. Better communication, because everyone handles the same information and knows the procedures by belonging to a single authority that dictates the guidelines to be followed in this system.

4. A single authority allows for greater control when making decisions.

5. Surveillance in a centralized system becomes much easier, because everything is governed by one way of governing and the system is homogeneous, they do not have to run after many branches

The truth this is a question with a little difficulty, because each system has its pros and cons, and we come from a society where the most governance comes from the centralized system, because so far it has been the only system that we mostly know, I think that if you manage to implement the decentralized system in a lot of countries, its management for business would become much easier to use for users.

In my country Venezuela, there are many businesses that already have cryptocurrencies as a payment alternative and in this way they are expanding the options to acquire the products of their customers. But I don't think that only one system can be used for a business, because the two interrelate and coexist in a perfect way. I think you can study the possibility of implementing two business models where experimental processes are carried out with each of the systems, to test their success over time.

I mention this because we have to take into account that not all users are updated with the latest technology, not everyone knows what a cryptocurrency or a virtual wallet is, it is a new world that is constantly growing and we cannot displace those who do not handle this type of information.

I am going to use TRONSCAN to perform this activity and I am going to use the TRX currency for the example and also the bitcoin currency to see the difference of a decentralized and a centralized contract.

We go into the TROSCAN application, we can go directly from our Steemit billboard.

Once in the TROSCAN application, we put the TRX contract "TKAtLoCB529zusLfLVkGvLNis6okwjB7jf" in the search engine.

Once it has been located, we go to where it says contract and click.

We will be able to see that no information about this token appears.

But if we make an example with the bitcoin token, we will be able to see a big difference. In the search engine we put the address of the contract "TN3W4H6rK2ce4vX9YnFQHwKENnHjoxb3m9".

place ourselves in the contract and we will be able to see the code.
