Oracle as a data delivery tool for decentralized autonomous organizations

Abstract

The subject of the study. The effective functioning of decentralized autonomous organizations<br> (DAOs) is associated with moving from the digital level to the real level in order to find or provide<br> information and communicate with the real environment. Obtaining or transmitting necessary<br> information about certain real–world facts, or information from other digital databases that cannot<br> interact directly with the DAO, is provided through oracles as intermediaries between decentralized<br> databases and real–world events.<br> Results of work. In this article, we consider the oracle as a tool for collecting information for DAO,<br> able to ensure transition of information from the unstable and unsecured physical world in the digital<br> environment of blockchain technology, where information acquires new characteristics and values.<br> Oracle, as a tool with a function of information delivery, combines the functions of finding the necessary<br> information with the functions of ensuring the authenticity and encryption of data in the required format.<br> Conclusions. This article gives a general understanding of the concept of the oracle, and its<br> significance for the work of DAO, as well as development of digital projects built using blockchain<br> technology. Classification of oracles for work with DAO is also given together with characteristics of<br> their possible role for organization of data supply. In addition, the possibility of building a DAO with oracle<br> functions to perform non–standard tasks for the transportation and adaptation of information for<br> various purposes in a blockchain environment is considered. The article also presents main problems<br> that may arise in interactions of oracles with DAO, and suggests possible solutions.
