A blockchain based appllication that holds the data and identity of users securely for hassle-free verification at institutes like banks, colleges and others.
The blockchain can be verified by a bitcoin-like consensus rule and the data is verified using the proof of existence protocol.
The addition of new data to the identity block is done by the authorities itself and whenever a user wants to send some parts of his data to a firm, he can do so by scanning a QR code at the firm and selecting the required docs in the pop up he gets in his/her device. The firm confirms the "transaction" and verification is done in drastically lesser time than the conventional processes.
