This repository contains the latest version of the CAKE approach presented in the paper "Fine-grained Data Access Control for Collaborative Process Execution on Blockchain" (DOI: 10.1007/978-3-031-16168-1_4; slides are available on SlideShare). For the Algorand-based implementation, please check out github.com/apwbs/CAKE-Algorand!
For the impatient: in this Docker Hub repository you can find readily available Docker Images to play with the Ethereum and Algorand implementations of the CAKE approach!
More information on the project, its requirements and a step-by-step guide to its use are contained within the Wiki.
