Cybersecurity is a very fast growing field in Computer Science, especially since hackers continue to become more powerful and much smarter, and the need for protection from these hackers also continues to grow. One of the well-known technologies in the field of Cybersecurity is Blockchain, a software that is mainly used as a database to keep track of financial transactions. This is how Blockchain works: when a user needs to make a transaction, they submit a request for one. The request to make a transaction is transported to a web of computers around the world which work on deciding whether the request is valid or not. This is what makes Blockchain secure: the copy of the request will only be approved if it matches both the sender’s and the receiver’s request, and if it is a fake request conjured by a hacker, it will not be approved. After the request is tested to make sure it is not unsafe, it is then arranged into blocks which will act as a chain of history that can not be erased. At this point, the transaction has finished. Even though as of right now Blockchain has revolutionized the exchange of money, there are many uses and advantages of Blockchain that are unknown at the moment.
