DVCS Oracle and the Task of Copyright Preservation in Blockchain-Based Technology

the authors address the problem of copyright registration. The authors show the shortcomings of existing copyright confirmation systems based on blockchain platforms, and provide solutions that eliminate these shortcomings. A distinctive feature of the proposed solution is using a bundle of a blockchain platform with an input DVCS Oracle based on the Litoria DVCS hardware-software complex used to perform the copyright registration function. The blockchain platform is entrusted with the classic task of preserving documents confirming copyright. Authors conduct a smart contract in the Solidity language, which performs the creation of a document and its issuance at the user’s request.
