b#IDs allow traceability between every data point through blockchain integration


Bluenumber (B#) is an ethical digital ecosystem:
Digital identity, blockchain, a control tower, analytics, data market, and partner apps, integrated seamlessly together


b#IDs are universal digital Identities for people, places, organizations, and things

b#IDs are free

b#IDs were first introduced at the United Nations in 2015 as a tool to track and measure the Sustainable Development Goals (SDGs) from a beneficiary-centric perspective. We quickly realized b#IDs had the potential to revolutionize the data market and reassert individuals’ agency over their data.
