2021 (English)In: Third International Workshop on Blockchain and Data Management (BlockDM 2021), in conjunction with the 37th IEEE International Conference on Data Engineering (ICDE), April 19, 2021, Chania, Crete, Greece, 2021Conference paper, Published paper (Refereed)
Abstract [en]

We envision PDS2, a decentralized data marketplace in which consumers submit their tasks to be run within the platform, on the data of willing providers. The goal of PDS2is to ensure that users maintain full control on their data and do not compromise their privacy, while being rewarded for the value that their data generates. In order to achieve this, our marketplace architecture employs blockchain technology, privacy-preserving computation and decentralized machine learning.

We then compare different potential solutions and identify the Ethereum blockchain, trusted execution environments and gossip learning as the most suitable for the implementation of PDS2. We also discuss the main open challenges that are left to tackle and possible directions for future work
