Privacy
Privacy on the blockchain is another critical issue that needs to be addressed.

The same goes for the private financial dealings of many high-profile or high-net-worth individuals. Privacy is highly valued in the internet age and blockchains must be able to provide this option to users if they are to achieve mass adoption.
