 Ethereum 2.0 is designed to be light client friendly. This allows low-resource clients such as mobile phones to access Ethereum 2.0 with reasonable safety and liveness. It also facilitates the development of "bridges" to external blockchains. This document suggests a minimal light client design for the beacon chain that uses the concept of "sync committees" introduced in [./beacon-chain.md](the the light-client-friendliness beacon chain extension).
