State channels are a technique for performing transactions and other state transitions in a second layer built on top of a blockchain. State channels make blockchains more efficient by moving many processes off-chain, while still retaining a blockchain’s characteristic trustworthiness. Payment channels are a type of state channel that allows users to make "off-chain payments" to each other. The term "state channels" generalizes this approach beyond payments.
Counterfactual is building a generalized framework for native state channels integration in Ethereum-based decentralized applications.

FunFair's Fate Channels
A Fate Channel is a State Channel opened for the duration of a gaming session, supporting custom gaming messages between the FunFair client and server. The only transactions on the blockchain occur at the beginning and end of the gaming session.
