Algorand is a Boston based company that is developing a blockchain network with a Pure Proof of Stake (PPoS) consensus mechanism. Algorand's decentralized platform is designed to enable faster transaction times and remove some of the technical barriers of creating scalable DApps. Algorand was founded by Silvio Micali, a pioneer in the field of cryptography.

Cardstack is a blockchain technology company that is developing an open-source framework and consensus protocol to make blockchains more usable and scalable. Their goal is to create a decentralized modular smart contract ecosystem. The Cardstack network is powered by the Ethereum-based CARD token.

Rise is building a blockchain development platform with dPoS consensus. Their protocol uses a Delegated Proof-of-Stake (dPoS) consensus mechanism and will be powered by the RISE coin. They hope to significantly improve transaction times and reduce fees, while providing developers with a tool set to create DApps in several programming languages.
