Light is a protocol built on Solana introducing ZK compression, a new primitive that enables the secure scaling of state directly on the L1.Hyperscale state: Solana users and program developers can opt-in to compress their on-chain state via the Light Protocol smart contracts. This reduces state cost by orders of magnitude while preserving the security, performance, and composability of the Solana L1.A new design space for computation: compressed state via Light natively supports custom ZK compute, enabling previously impossible computation designs on Solana.
