Current blockchain systems suffer from extremely low throughput and high latency, thus hindering the mass adoption of decentralized applications While significant efforts have been put on improving blockchain scalability by using more sophisticated consensus mechanisms, they are fundamentally bottlenecked by the processing speed of a single node, which is still far from satisfying the requirement of mass adoption In this talk, we will describe a new dimension for improving blockchain scalability: off-chain (layer-2) scaling, and discuss how it will become the inflection point for dApp mass adoption Off-chain scaling techniques such as state channel and side chains are able to support truly scale-out dApps with better privacy and no compromise on the trust-free guarantee Despite its high potentials, off-chain scaling is still in its infancy with challenges remaining unsolved, such as generalized state channel construction, state routing, state availability problems, etc We propose Celer Network as the first coherent architecture that meets these challenges Celer embraces a layered architecture with clean abstractions that enable rapid evolution of each individual component, including generalized state channels that supports fast and generic off-chain state transitions; a provably optimal payment routing algorithm that achieves orders of magnitude higher throughput compared to state-of-the-art solutions; a powerful development framework and runtime for off-chain dApps; and an incentive-aligned mechanism that provides stable liquidity and high off-chain state availability We provide our vision for Celer Network 2 0, a grand unification of all off-chain scaling technologies into a single solution
