This paper is written in poor-quality English, so adjust your expectations. Additionally, it is focused at the conceptual level, and contains a proposal only. Having said that, it succinctly describes the communications problem in the use of e-portfolios in cooperative education, and describes how a blockchain-based solution would address the issue. The paper is short of the many details that would need to be attended to in creating such a solution, but it's a glimpse into a possible future.
