Boolberry is a cryptocurrency based on CryptoNote technology. Boolberry's major benefit is to provide much stronger privacy to both the senders and receivers of transactions. The destination of a transaction can only be determined by its real recipient and transactions cannot be linked to a single sender. Each transaction could have many equally possible senders, and an attacker cannot determine which one it was. There is an aliasing facility built into the blockchain so that people or programs can send money to, for example, '@zoidberg' instead of a long address.
Decred aims to build a community-directed digital currency whose security, adaptability, and sustainability make it a superior long-term store of value. It is achieving this aim by building the world's first truly decentralized autonomous organization.
