Dock is a decentralized data exchange protocol that gives users more control over their data and identities online. Their goal is to enable interoperability between networks, and to allow consumer Apps to access personal data with the full control of the end user. The Dock network is powered by the Ethereum-based DOCK token.

The Sovrin Foundation is a non-profit organization dedicated to establishing the Sovrin network. Their goal is to create a purpose-built blockchahin, with a native token, that will facilitate creating and maintaining self-sovereign identities. The Sovrin token will provide incentives to value exchange that preserves privacy. It could also enable a global marketplace for digital credentials and personal data.
This is an important project that has lofty goals, but has the potential to revolutionize several major industries.
