Hileman, Garrick and Rauchs, Michel, 2017 Global Blockchain Benchmarking Study (September 22, 2017). Available at SSRN: https://ssrn.com/abstract=3040224

“The first global blockchain benchmarking study presents a systematic and comprehensive picture of a rapidly evolving industry, examining how blockchain and distributed ledger technology (DLT) are being used in the public sector and enterprise. The study analysed non-publicly available data gathered from over 200 central banks, other public sector institutions, DLT start-ups, and established companies. Findings from the study include which protocols central banks and are testing (57% of surveyed central banks are experimenting with the Ethereum codebase), targeted use cases, emerging revenue models, timing of deployment, and key challenges.”
