At the end of 2019, research firm Forrester and Big Four firm Ernst & Young, or EY, published a report surveying the adoption of public blockchains by enterprises. Findings revealed that 75% of respondents were likely to use a public blockchain in the future.
Although this was the case, the report also found that most enterprises were still using private blockchains to ensure security, privacy and scalability. What was also noted in the survey as the top three concerns regarding public blockchain networks were a lack of maturity, security and privacy issues.
