Distributed Ledger technologies (often referred to as ‘Blockchain’) are amongst the most high-profile of all currently emerging technologies that will drive enterprise digital transformation. Outside of Cryptocurrency, which we do not discuss in this report, Use Cases for distributed ledger technologies include Supply Chain Audit, Immutable Records, Digital Identity, Smart Contracts, and Proof of Work. All of these Use Cases are anchored in the key concept of enabling increased trust within complex systems. This report examines the scale of the market opportunity associated with these diverse distributed ledger propositions. The focus is on quantitative analysis of revenues for distributed ledger applications, including vertical and geographic analysis. For further discussion of the market for distributed ledger, including analysis of key market trends, vendor landscape, and analysis of historic deployments, see the Distributed Ledger Technology Insight Report.
