Content Distribution Network (CDN) is one of the most established technology for improving application and media service providers’ scalability, quality of service (QoS), and quality of experience (QoE). A hybrid content delivery network (CDN) with peer-to-peer (P2P) networking (CDN-P2P) is one strategy for further improving the scalability and QoS/QoE. However, CDN-P2P suffers from peer churning and free riding due to the inexistence of stimulating monetary incentives for the participating peers in the P2P overlay. Furthermore, to incentivize participating peers according to the peer contributions, it is not clear how much a peer contributes back to the overall content distribution capacity. To this end, this manuscript proposes a cryptocurrency incentivized crowdsourced P2P content delivery network (CROWD-CDN). CROWD-CDN monetizes the services of seeds supplying peers according to their contribution to the overall CDN content distribution capacity. CROWD-CDN employed blockchain-based cryptocurrencies and smart contracts for the monetization of peers. Additionally, CROWD-CDN utilizes the container-based virtualization of the peer nodes enabling CDN providers for transparent monitoring of peers’ contribution and securing the CDN contents at the peer in the isolated container. Lastly, we provide a proof of concept simulated testbed for the dimensioning of different variants of the proposed hybrid architecture and validating the provisioning of monetary incentives to peers.

内容分发网络 (CDN) 是用于提高应用程序和媒体服务提供商的可扩展性、服务质量 (QoS) 和体验质量 (QoE) 的最成熟技术之一。具有对等 (P2P) 网络 (CDN-P2P) 的混合内容交付网络 (CDN) 是进一步提高可扩展性和 QoS/QoE 的一种策略。然而，CDN-P2P 由于在 P2P 覆盖中不存在对参与同行的刺激性货币激励措施而遭受同行流失和搭便车的困扰。此外，为了根据对等点的贡献来激励参与的对等点，尚不清楚对等点对整体内容分发能力的贡献有多大。为此，本手稿提出了一种加密货币激励的众包 P2P 内容交付网络 (CROWD-CDN)。CROWD-CDN 根据种子供应商对整体 CDN 内容分发能力的贡献，将种子供应商的服务货币化。CROWD-CDN 采用基于区块链的加密货币和智能合约来实现对等方的货币化。此外，CROWD-CDN 利用对等节点的基于容器的虚拟化，使 CDN 提供商能够透明地监控对等方的贡献并保护隔离容器中对等方的 CDN 内容。最后，我们提供了一个概念验证模拟测试平台，用于确定所提出的混合架构的不同变体的尺寸，并验证向同行提供货币激励。CROWD-CDN 采用基于区块链的加密货币和智能合约来实现对等方的货币化。此外，CROWD-CDN 利用对等节点的基于容器的虚拟化，使 CDN 提供商能够透明地监控对等方的贡献并保护隔离容器中对等方的 CDN 内容。最后，我们提供了一个概念验证模拟测试平台，用于确定所提出的混合架构的不同变体的尺寸，并验证向同行提供货币激励。CROWD-CDN 采用基于区块链的加密货币和智能合约来实现对等方的货币化。此外，CROWD-CDN 利用对等节点的基于容器的虚拟化，使 CDN 提供商能够透明地监控对等方的贡献并保护隔离容器中对等方的 CDN 内容。最后，我们提供了一个概念验证模拟测试平台，用于确定所提出的混合架构的不同变体的尺寸，并验证向同行提供货币激励。
