A Distributed Blockchain-based Video Sharing System with Copyright, Integrity, and Immutability

Abstract

Today's video-sharing systems are platforms that have been developed to be a hub for the introduction and sharing of videos created by video creators from all over the world. These systems generate significant revenue through advertising or copyright transferring they receive from video viewers, which share only certain percentage with video creators. However, To make more profit for video creators, in this paper we proposed a distributed video sharing architecture with the possibility of performing financial transactions that works on the Ethereum. In this new architecture, the Blockchain network separated from storage; because video storage in Blockchain results to be costly for mining in the nodes in the network. Ethereum's smart contract is responsible for monitoring the validity, transparency, immutability, integrity, and security of transactions as well as controlling video access. On the other side of the architecture, there is an Ethereum-compatible distributed file storage called Swarm for video storage. Due to the lack of video storage in the Blockchain network, the integrity of the videos is questionable. To solve this problem in the proposed scheme, a Merkel tree of video hashes in the swarm is created and stored in the Blockchain to ensure the immutability and integrity of the videos and, to be transparent and valid to everyone. Finally, the performance of the proposed architecture in terms of security, structure distribution, downtime probability, fault tolerance, transparency, content integrity, immutability, and sustainability has been compared with similar systems and its performance has been proven.
