- Abstract summary: Various data-sharing platforms have emerged with the growing public demand for open data and legislation mandating certain data to remain open.
Most of these platforms remain opaque, leading to many questions about data accuracy, provenance and lineage, privacy implications, consent management, and the lack of fair incentives for data providers.
With their transparency, immutability, non-repudiation, and decentralization properties, blockchains could not be more apt to answer these questions and enhance trust in a data-sharing platform.

- Abstract: Various data-sharing platforms have emerged with the growing public demand
for open data and legislation mandating certain data to remain open. Most of
these platforms remain opaque, leading to many questions about data accuracy,
provenance and lineage, privacy implications, consent management, and the lack
of fair incentives for data providers. With their transparency, immutability,
non-repudiation, and decentralization properties, blockchains could not be more
apt to answer these questions and enhance trust in a data-sharing platform.
However, blockchains are not good at handling the four Vs of big data (i.e.,
volume, variety, velocity, and veracity) due to their limited performance,
scalability, and high cost. Given many related works proposes blockchain-based
trustworthy data-sharing solutions, there is increasing confusion and
difficulties in understanding and selecting these technologies and platforms in
terms of their sharing mechanisms, sharing services, quality of services, and
applications. In this paper, we conduct a comprehensive survey on
blockchain-based data-sharing architectures and applications to fill the gap.
First, we present the foundations of blockchains and discuss the challenges of
current data-sharing techniques. Second, we focus on the convergence of
blockchain and data sharing to give a clear picture of this landscape and
propose a reference architecture for blockchain-based data sharing. Third, we
discuss the industrial applications of blockchain-based data sharing, ranging
from healthcare and smart grid to transportation and decarbonization. For each
application, we provide lessons learned for the deployment of Blockchain-based
data sharing. Finally, we discuss research challenges and open research
directions.
