Pillar is developing a decentralized solution for data management that will be centered around the Pillar wallet. Their goal is for the wallet to evolve to include other online services that are based on centralized servers. Pillar Wallet will provide a platform where personal information is managed securely from the user's phone, where they will be able to verify their identity, and choose when and what to share.

uPort is developing a self-sovereign identity platform for the Ethereum blockchain. It will consist of a wallet that will allow users to sign transactions and manage their keys and data more easily, as well as tools that will allow developers to issue credentials and request data from other DApps that use the paltform. uPort is a ConsenSys portfolio company.
