In POA Network, identity of individual validators plays a major role for selected consensus. We propose additional checks of identity, performed in a decentralized way. Proof of Identity DApps is a series of decentralized applications focused on connecting a user's identity to his/her wallet. Applications can be run on any Ethereum-compatible network. Using Proof of Physical Address, a user can confirm his/her physical address. It can be used to prove connection between residency and a network address (wallet). User submits a form with his physical address details (name, state, city, etc) on DApp main page. This data is added to the PoPA contract deployed to the network and thus a correspondence between a wallet and physical address is registered in the contract. However, this correspondence is not yet verified.
