IOST (Internet of Services Token) is a blockchain platform that is focused on improving transaction speed and scalability. IOST has a unique Proof of Believability consensus mechanism that is based on past contributions and behavior.
The company claims that their platform will increase security and efficiency compared to other platforms. IOST uses a sharding technique that splits the network into smaller ones and randomly assigns tasks for the nodes on the network.

Mainframe is creating a blockchain development platform for decentralized applications. Their marketing materials place a strong emphasis on encryption, privacy, and interoperability. Onyx, a decentralized workplace messaging tool, is the first application to be built on the Mainframe network.
Mainframe is powered by the MFT token.

GoChain is building a blockchain focused on speed and scalability. GoChain's protocol uses a Proof-of-Reputation (PoR) consensus mechanism and will be powered by the GO coin. They hope to significantly improve transaction times and reduce fee with an architecture that will rely on nodes managed by large enterprises. Their marketing materials places a strong emphasis on energy efficiency and reducing the monopolizing influence of large mining operations that have reduced the decentralization of other networks.
