“Proof of Physical Address” DApp is an open source version of a proprietary and abandoned identity oracle by Consensys. https://medium.com/@ConsenSys/introducing-proof-of-physical-address-acf54fc95f21
A user can enter his physical address and sign a transaction with his Ethereum wallet, e.g. Metamask.
The oracle will send a postcard by snail mail to the user using Lob.com API
After the user receives that postcard he will type a code from the card to the DApp and sign one more transaction.
The DApp will oraclize user’s identity.
A user will have this oraclized identity in Oracles Metamask and can sign transactions with additional identity onchain. We plan to embed this oracle to ICO Wizard DApp.
