5G technology is expected to enable many innovative applications in different verticals. These applications have heterogeneous performance requirements (e.g., high data rate, low latency, high reliability, and high availability). In order to meet these requirements, 5G networks endorse network flexibility through the deployment of new emerging technologies, mainly network slicing and mobile edge computing. This article introduces a distributed blockchain-enabled network slicing (DBNS) framework that enables service and resource providers to dynamically lease resources to ensure high performance for their end-to-end services. The key component of our framework is the global service provisioning (GSP), which provides admission control for incoming service requests along with dynamic resource assignment by means of a blockchain-based bidding system. The goal is to improve users' experience with diverse services and reduce providers' capital and operational expenditures.

DBNS：用于 5G 网络的分布式区块链网络切片框架

5G 技术有望在不同的垂直领域实现许多创新应用。这些应用程序具有异构性能要求（例如，高数据速率、低延迟、高可靠性和高可用性）。为了满足这些要求，5G 网络通过部署新兴技术（主要是网络切片和移动边缘计算）来支持网络灵活性。本文介绍了一个分布式区块链网络切片 (DBNS) 框架，该框架使服务和资源提供商能够动态租用资源，以确保其端到端服务的高性能。我们框架的关键组件是全球服务供应 (GSP)，它通过基于区块链的投标系统为传入的服务请求提供准入控制以及动态资源分配。
