DFINITY is a public network of client computers providing a "decentralized world compute cloud" where software can be installed and run with all the usual benefits expected of "smart contract" systems hosted on a traditional blockchain

GoChain is a scalable, high performance, low cost, and decentralized cryptocurrency and blockchain that supports smart contracts and distributed applications.

Scaling Blockchain Computation to enable interchain and limitless real world applications

Connext is a layer two scaling platform that lets Ethereum projects enable lightning fast transactions for their users. Connext lets you set up and use a state channel hub. By securely moving transactions to a networked, trustless, off-chain layer, state channels minimize the transaction fees and times that prevent blockchain apps from scaling. To date, state channel implementations have largely been custom-built or research-focused. We make leveraging the power of state channels easy. Users deposit their funds into a smart contract with your Connext Hub. Then, they can pay any other user that is also connected to your Hub simply by signing a state update. Funds remain secure because parties can settle disputes on the underlying blockchain at any time.
