  Decentralized applications (DApps), which are innovative blockchain-powered
software systems designed to serve as the fundamental building blocks for the
next generation of Internet services, have witnessed exponential growth in
recent years. This paper thoroughly compares and analyzes two blockchain-based
decentralized storage networks (DSNs), which are crucial foundations for DApp
and blockchain ecosystems. The study examines their respective mechanisms for
data persistence, strategies for enforcing data retention, and token economics.
In addition to delving into technical details, the suitability of each storage
solution for decentralized application development is assessed, taking into
consideration network performance, storage costs, and existing use cases. By
evaluating these factors, the paper aims to provide insights into the
effectiveness of these technologies in supporting the desirable properties of
truly decentralized blockchain applications. In conclusion, the findings of
this research are discussed and synthesized, offering valuable perspectives on
the capabilities of these technologies. It sheds light on their potential to
facilitate the development of DApps and provides an understanding of the
ongoing trends in blockchain development.
