This IDC Pivot Table highlights the impact of COVID-19 on worldwide blockchain spend, providing a pre- and post-comparison of a COVID-19 impacted market. It highlights IDC's predictions by industry and use case for the United States and the rest of the world, comparing the latest blockchain forecast (April Version 1, 2020) with preliminary estimates from earlier in the year (1H19 Pre-COVID-19). Technology suppliers can utilize the information to help reprioritize and refocus their efforts toward more resilient segments. The 1H19 Pre-COVID-19 forecast is only an estimate, updating for non-COVID-19 factors in relation to previously published blockchain forecasts (2H18 from August 2019). For this worldwide blockchain forecast, IDC uses a global, detailed market model to forecast total blockchain spending. The components of the model used to determine a market size and forecast for a use case include demand-side data, supply-side data, industry trends, and the economic outlook to generate a model of technology spending. Please note that to better reflect the fast-changing market conditions deriving from the coronavirus pandemic and from governments' decisions, IDC's forecasts are being continuously updated. Therefore, there might be some temporary misalignment when comparing this data with other IDC products that will be released.
