Ethereum Blue is a cryptocurrency released in October 2017 which aims to add extra security to the smart contracts used on the blockchain to avoid risks from frauds. The system will scan the software and the ID of every user before receiving the tokens. The platform itself is centralized to ensure high control and less transparency for the data to stay safe. Ethereum Blue has created a two-factor authorization defense system which requires more personal data for the users to be logged in the platform. Usually, those kinds of defense mechanisms take time to be hacked and while this is done the developer team will be aware of the attempt and take measures to avoid the fraud and protect the account and the personal data within.
