Blockchain is a growing list of records, interconnected by cryptography. These records are called blocks and each of them is connected to the previous one and to the next one. All blocks together build a chain, from where the name came from. The theme of this paper is the implementation of Blockchain technology in booking management. Considering that Blockchain's new technology, which most people are unfamiliar with, to get to the major part of the topic, paper begins with general facts about it. Following are explanations of each of these facts in order to substantiate their meaning. The main advantage of Blockchain technology is security. Security on a greater level than the technologies used so far could have achieved. This security is achieved by: algorithms that define the way in which Proof of Work and Proof of Stake are reached, blocks containing all information and are interconnected to make extremely difficult for attackers to interfere, transparency, and connectivity. The aim of this paper is to show how such technology influences daily life patterns. After getting to know the way Blockchain works in the first part of the paper, there follows a description of the implementation that is interwoven with comparisons with common databases. The advantages of Blockchain are displayed through a web application that serves to manage booking.
