    On-chain vs. off-chain storage for supply- and blockchain integration
    (it - Information Technology: Vol. 60, No. 5-6, 2018) Hepp, Thomas; Sharinghousen, Matthew; Ehret, Philip; Schoenhals, Alexander; Gipp, Bela
    Supply chains are the basis of most everyday life products. Both data integrity and authenticity of related information have severe implications for quality and safety of end-products. Hence, tamper-proof storage is necessary that prevents unauthorized modifications. We examine peer-reviewed blockchain technologies according to four criteria relevant to supply chains: On-chain storage, off-chain storage, verification cost and secure data sharing. Our evaluation yields an overview of concepts for modeling supply chain processes and points out that on-chain storage is currently not practical.
