Content sharing platforms such as Youtube and Vimeo have promoted pay per view models for artists to monetize their content. Yet, artists remain at the mercy of centralized platforms that control content listing and advertisement, with little transparency and fairness in terms of number of views or revenue. On the other hand, consumers are distanced from the publishers and cannot authenticate originality of the content. In this paper, we develop a reliable and fair platform for content sharing without a central facilitator. The platform is built as a decentralized data storage layer to store and share content in a fault-tolerant manner, where the peers also participate in a blockchain network. The blockchain is used to manage content listings and as an auditable and fair marketplace transaction processor that automatically pays out the content creators and the storage facilitators using smart contracts. We demonstrate the system with the blockchain layer built on Hyperledger Fabric and the data layer built on Tahoe-LAFS,and show that our design is practical and scalable with low overheads.

使用区块链进行内容共享的可靠、公平和去中心化市场

Youtube 和 Vimeo 等内容共享平台已经为艺术家推广了按观看次数付费模式,以通过他们的内容获利。然而,艺术家仍然受制于控制内容列表和广告的中心化平台,在观看次数或收入方面缺乏透明度和公平性。另一方面,消费者远离出版商,无法验证内容的原创性。在本文中,我们开发了一个可靠且公平的内容共享平台,无需中央协调人。该平台构建为分散的数据存储层,以容错方式存储和共享内容,其中对等方也参与区块链网络。区块链用于管理内容列表,并作为可审计且公平的市场交易处理器,使用智能合约自动向内容创建者和存储服务商付款。我们展示了基于 Hyperledger Fabric 的区块链层和基于 Tahoe-LAFS 的数据层的系统,并表明我们的设计是实用且可扩展的,并且开销很低。
