Connext

Connext's mission is to bring blockchain to the next billion users by enabling instant, low cost Ethereum transfers. They achieve that by using generalized state channels to establish peer-to-peer Payment Channels that allow users to batch many Ethereum transactions into one netted transfer by using signed off-blockchain commitments rather than direct on-blockchain transactions. This improves the scalability of transfers across the Ethereum ecosystem, and also creates one fast and seamless experience between wallets, browsers, and applications.
