This document describes the research efforts as conducted to build a privacy-preserving and authenticity-preserving KRAKEN architecture. The goal of this deliverable is to give a high-level overview of research results on cryptographic tools integrated and built for the KRAKEN architecture and on results on research questions motivated by the unique challenges of a privacy-preserving data marketplace. This deliverable extends the interim research report, D4.1 Progress report on cryptographic protocols for privacy-preserving data markets and SSI systems, with all research results that have been obtained as part of WP4.
