The anonymous nature of blockchains can pose a problem for user interaction in decentralized applications. Typically, users want to know who is on the other end of the interaction. In most existing applications, this problem is solved with identity providers. But these identities are usually tied to some user account, which cannot be easily linked to an account on the blockchain. The Ethereum blockchain offers support for smart contracts within which data can be stored, read, edited, or deleted. So, we decided to implement our identity provider using smart contracts where users could upload an identity for their Ethereum account. Additionally, we have added a user interface for interacting with the identity provider, which allows viewing and editing individual identities.
