BaaSid, short for Blockchain as a Service for ID, is a blockchain based network for securing personal authentication data. BaaSid divides and redistributes data related to personal information on a blockchain and does not rely on a centralized database to store this sensitive information. The network is powered by the Ethereum-based BAAS 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.

Aston is a decentralized document distribution network that enables users to better control their personal documents and professional certifications. It records, authenticates, and distributes identifying documents and information, and integrates biometric identification to ensure security.
Aston's platform is based on X-Chain architecture, which has a hybrid consensus mechanism. It combines a Proof of Forkability (PoF) mechanism with a Distributed Proof-of-Stake (dPoS) consensus protocol that stores and distributes data in 3rd dimension sub-chains.
The network is powered by the ATX coin.
