For supply chain organizations launching new blockchain projects, one of the most fraught considerations typically is whether to use a public or private ledger and what permission models. This decision affects functionality, security, compatibility with other stakeholders’ systems and, perhaps most important, competitive positioning for companies. It is important that supply chain decision‑makers can sort through the marketing hype to pick the best solution for their particular requirements. This paper explores important considerations in making the public‑versus‑private decision and demystify elements of the public-versus-private debate. The findings in this paper were gleaned from research as well as detailed interviews with blockchain users across diverse industries, geographies and applications. This paper is the third in a series covering the co‑creation of new tools for the responsible deployment of distributed ledger technology (DLT) in supply chains.
