Data Collection Framework Using a Lightweight Blockchain

Blockchain protocol has emerged in modern technologies in recent years. Significantly, the data collection frameworks are one of the most demanding fields of blockchain adaptation. However, the traditional approach relies on heavy computations, which require high-computing servers that cannot be affordable by all providers. This paper proposes a reliable and secure data collection technique, BSave, that employs a lightweight blockchain suitable for low-computing devices. BSave stores the data in a key-value database and enables two-way encrypted security on both keys and values. Compared to traditional approaches, the BSave proved its effectiveness in data-intensive environments.
