phd is a new currency that will allow students to pay for their education through a decentralized blockchain, using their smart phone to transfer funds.
It is being developed by a team at Ethereum and is the second blockchain that will use ethereum as the underlying technology.
This allows students to transfer money from one blockchain to another without using any external token, which is crucial for ethereum to work as a currency.
The platform is still in its early days and will need a lot of work, but its still a good example of a cryptocurrency that can be used as a payment platform for schools.
