Blockchain and Decentralized Information Markets
The increasing amount of interconnection in modern industry and research applications puts data exchange in the center. Even though data exchange has been solved on a technical level, the distribution and sharing of data with third parties creates additional non-technical challenges that are yet to be solved in many cases. Data privacy, data sovereignty and legal issues have to be faced. At the same time, businesses often require third parties to perform calculations on foreign data.
Goal of the Cadeia Project is to facilitate a decentralized peer-to-peer architecture with mechanisms for data distribution, data exchange and code execution - while providing proof of the provided service.
Enerchain is a smart market project aiming to decentralize energy product trading. Peer-to-peer trading between the parties becomes easily possible by using a blockchain technology. Traceability and replicability of transactions is guaranteed by the blockchain.

SUNI is an information marketplace which provides cross-domain access to all kinds of (raw) data. Additionally, SUNI provides it's users with the capability to execute functions on local remote data, even if the data is not publicly available. This allows data consumers to analyze data while maintaining data sovereignty for data owners. The methods and principles used in SUNI target research applications as well as industrial data space applications.
The HITeC Blockchain project is the first ever Blockchain project conducted with students from the University of Hamburg. The goal is to analyze and evaluate existing technologies, learn from their advantages and disadvantages and create a custom blockchain technology from scratch.
The increasing urbanization results in a rising demand for smart city platforms that optimize limited resources and thus save resources and increase the quality of living at the same time. Several systems have evolved in the past to address such issues by providing platforms for collecting, sharing, and processing urban data. However, these existing platforms only partially address challenges like fostering the participation of citizens, protecting their privacy, and assuring certain levels of quality of information. In this paper, we present the architecture of SANE as an open, citizen-centric, scalable, and privacy-preserving smart city platform. SANE is intended as open platform on which citizens can contribute data but also hardware, without any central authority or control. Moreover, citizens maintain full control on their data and its usage. SANE comes with rich and distributed data analytics functionality that is intended to help citizens to answer data-related question in the context of smart cities.
