Aergo is developing an SQL based smart contract platform that will allow developers to more easily share data and create DApps. Their platform will combine elements of public and private blockchain architectures and will have a hybrid BFT/dPoS consensus mechanism. The ERGO Hub will serve as a blockchain hosting service that will allow users to test and deploy their own blockchains. Their network is currently powered by the Etherem-based AERGO token.

Scatter is a browser extension for the EOS blockchain that enables users to sign transactions on the EOS blockchain. Users are able to sign transactions with their private keys from web applications without having to expose their personal information. The founders of Scatter are also developing the Reputation and Identity Layer (RIDL), which will provide a reputation system that will add trust and transparency to the DApp ecosystem.
