ShoCard is a digital identity and authentication platform built on a public blockchain data layer that uses encryption and data hashing to safely store and exchange identity data.

There is no privately held central location that holds user’s private information, and pieces of a user’s identification do not need to be spread to other services in order to authenticate or prove ownership of an account.
