Secret Data Validation #4

Closed ainsleys closed 5 years ago

ainsleys commented 5 years ago

Request

Enigma Secret Contracts enable dApps to compute over encrypted data. One simple use-case for this is validating the authenticity of a data set. This simple contract just checks to see if encrypted data inputs from different users are equivalent or not.

Solution Description

This solution should enable User A to upload a small dataset (email, phone number), and also enable a second user to submit their own dataset (with the same fields). Then, the secret contract should compare the two data sets. If they are equivalent, the secret contract should send an encrypted affirmation of this to User B, who has now verified their data set against user A. If they are not equivalent, the user should receive a false response.

This will involve:

Implementation Details and Data Flow

  1. User A submits data via a UI (email, phone number).
  2. This data submission is encrypted locally via Enigma-JS and submitted to the secret contract.
  3. User B submits data via a UI (email, phone number)
  4. This data submission is encrypted locally via Enigma-JS and submitted to the secret contract.
  5. The secret contract (after receiving both datasets) executes a comparison to check equivalency.
  6. The secret contract returns either a False or True response.
  7. If data are equivalent, User B and User A are notified via the UI.
  8. If data are not equivalent, both users are notified via the UI.

Success

A working application, which should have a simple React-based UI (or similar), enable the solution, and handle failure (i.e., displays a meaningful message when improperly formatted data is submitted).

@gitcoinbot https://github.com/bshevchenko/enigma-data-validation it's done just need some gas to submit work via gitcoin contacted @ainsleys

bshevchenko commented 5 years ago

Contract compares submitted dataset with the previous one. Frontend is based on discovery CLI preset and article, but little bit refined.

bshevchenko commented 5 years ago

The reason why there is no list of datasets is the same as why we are not notifying user A – smart contract or some other storage is needed for that, that would serve data and push notification to subscribed user A. This was discussed with @ainsleys couple of days ago
