A blockchain-enabled scalable and secure architecture for cloud big data storage using sharding and swarming.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cloud computing enables on-demand access to centralized resources, including applications, networks, and storage, while big data and blockchain technology drive innovation in data management. The rapid growth of data stored in the cloud poses significant challenges, such as ensuring scalability, real-time analytics, and compliance with regulatory frameworks. Big data systems often struggle with elasticity, as many current solutions fail to provide rapid scalability under fluctuating workloads. To address these challenges, blockchain technology integrates big data storage in the cloud, creating a secure and efficient framework. Blockchain offers cryptographically secure, decentralized data management that enhances the reliability and value of big data for analysis. The novel architecture integrates sharding and swarming techniques to overcome the scalability limitations of blockchain-based big data systems and sharding partitions data into smaller fragments stored and accessed using unique partition keys, improving manageability and reducing system load. Swarming complements this approach by enabling parallel data retrieval from the fastest and nearest nodes, minimizing latency and enhancing access speed. An optimized Proof of Work (PoW) mechanism further ensures computational fairness and reduces energy consumption, addressing critical efficiency concerns. This integration of blockchain with cloud-based big data storage provides a transformative solution for secure, scalable, and high-performance data management, advancing decentralized applications and analytics capabilities.
