There have been many researches and attempts to overcome various problems of digital contents distribution system. However, the conventional centralized system structure mentioned above has not yet provided adequate solutions. Obviously, the purpose of creation and use of contents are the same yet it is structure focusing in profit and authority that it eventually gives birth to a management perspective also has different formal rules. In order to overcome these problems and to secure the efficiency, reliability, and proper profit distribution of copyright owners (creators) a new structure.

Is needed, DiCoBlock team uses block-chain technology to establish a digital contents distribution system based on a decentralized system that could not be achieved with the current system, and it would provide digital contents copyrights check and distribution based on an auction service. This can ensure both transparency and reliability of the transactions, according to the characteristics of the block chain, and it is a reasonable platform for users. The DiCoBlock platform is a digital content distribution service, not a single service, and along with users, it is possible to define the price of digital contents which were not possible through conventional auction and reverse auction services. Unlike existing services with high entry barriers in the distribution market, one creator and small creative companies can actively participate. By providing standardized APIs and SDKs, it is easy to securely access data from third-party applications and services, thereby creating a digital eco-friendly ecosystem. It also uses the DiCo password to be used in the DiCoBlock service for issuance of copyright and distribution activities.
