In which allows them to avoid committing any

In today’s world, which we can call it as a centralized world as it consists of more of centralised social structures unlike the world that use to be before the age of agriculture began, where people use to live in small groups knowing each and every one in the group which allows them to avoid committing any kind of bad actions, which we can call it as a decentralised social structure.  Taking the centralised society in to context, in this society there are large number of centralised groups where people are rarely aware of the other people in their group as well as other groups. In this scenario, if someone wants to have a transaction or a communication or may be any kind of deal, they have to face a major question about how to trust the other person to have a communication or a transaction or any kind of a deal. There exists some of the processes, with which people can go through and can judge whether they can trust the other person or not, but these are not 100% reliable and very slow process. These processes include agreements, the agreement is a set of terms on which the two persons agree to follow while they are doing a transaction or implementing any kind of deal. There are numerous kinds of agreements which are dealt by a third person or can be called as a third party or an a mediator other than these two persons in between whom the agreement will be made. The so called agreements or contracts were used in business, personal relationships like marriages, politics., what not almost everywhere in every kind of relationship. As the world is changing tremendously with rapid growth, the usual contracts which are made on paper or soft copies with the third parties seems to be a slower process as a result a new contracts specifically named as Smart contracts were came in to tremendous use in recent years. The word Smart Contracts was first introduced in 1996 by the computer scientist named Nick Szabo. This is going to be furtherly explained under the heading Smart contracts. These smart contracts can be done using the technology called Blockchain and the most specifically designed platform for the use of smart contracts is Ethereum. A clear explanation of Blockchain and Ethereum will be followed in the theoretical background.
