As the number of blockchain (BC) platforms providing specific features increases, selecting a platform that fits all requirements needed for a specific case becomes a cumbersome task. For example, not only are BCs' technical details relevant, but also their intrinsic characteristics (e.g., cryptocurrency price) must be considered in selecting a BC for a given case. Hence, the management of data stored in multiple BCs and the selection process are not straightforward due to the myriad platforms and both technical and economic details (e.g., BC throughput and the underlying price fluctuation). This article defines a novel refinement flow (based on the policy continuum) of high-level BC selection policies to low-level BC transactions. Experiments with the BC selection framework developed applying policy-based management (PBM) in the BC context do show that such synergy simplifies data management in multiple BCs driven by user requirements (e.g., based on costs or performance policies). The performance analysis of the framework demonstrates the successful employment of PBM for BC selections with minimal overhead.

基于策略的区块链选择

随着提供特定功能的区块链 (BC) 平台数量的增加，选择适合特定案例所需的所有要求的平台成为一项繁琐的任务。例如，在为给定案例选择 BC 时，不仅必须考虑 BC 的技术细节，还必须考虑其内在特征（例如，加密货币价格）。因此，由于众多平台以及技术和经济细节（例如，BC 吞吐量和潜在价格波动），存储在多个 BC 中的数据的管理和选择过程并不简单。本文定义了高级 BC 选择策略到低级 BC 交易的新细化流程（基于策略连续体）。在 BC 上下文中应用基于策略的管理 (PBM) 开发的 BC 选择框架的实验确实表明，这种协同作用简化了由用户需求驱动的多个 BC 中的数据管理（例如，基于成本或性能策略）。该框架的性能分析证明了 PBM 以最小的开销成功地用于 BC 选择。
