Ethereum android was created to enable Aabrod varity of use cases where mobile devices need to connect to Blockchain technology based on Ethereum. Smart contract extends the applicability of Blockchain in various decentralized cases. Every connection to the blockchain is only done via trusted end point using certificate pinning and end to end encryption. The Decentralized application provide flexibility, smart degree aims to provide a decentralized solution to manage degree. Smart degree currently uses Ethereum as backing blockchain.
