15 percent of banks to adopt blockchain by 2017
"IBM claims, in a recently published report, that they expect 15 percent of major banks to have implemented blockchain technology by 2017. The estimate is the result of a survey IBM performed on 200 banks and financial institutions, on their progress on blockchain technology."

"15 percent of banks to adopt blockchain by 2017" ... i wouldn't be surprised if it was more. It's not that hard to implement if there is a desire. Most banks would have been thinking about this in 2014/2015 and begun to prepare their IT to receive it. By the end of 2017 I would imagine this would be more likely to be near 30% than 15%. Thanks for the comments I appreciate the support. Stephen
