Problem Statement

Ethentity is a dApp that allows users to have their identity and government ID verified by other, previously verified users. It's done in a way that protects the users' personal information by splitting this information into chunks that can individually be verified but are not individually significant.

Solution

Stack:We're using the following technologies:Arbitrum for our L2 transactions.Kleros for the dispute arbitration.IPFS to securely store encrypted photos.Approach:A user verifies their identity by taking a photo of them holding their government ID (Passport) on app.ethentity.io and paying a verification fee.The user uses the Ethentity app to create three chunks, these are duplicates of the photo above each only showing a part of the passport #.Verifiers pick an ID chunk to verify. They can't verify more than one chunk of the same ID.A verifier, who is a verified user, is incentivized by a verification reward. This is the fee that the prover pays divided by the number of chunk verifiers.A verifier stakes their ETH to be able to verify ID chunks, they can be penalized if their verification was challenged and rejected.Once all three chunks of a given ID are verified, then that user's ID is considered to be verified.
