Light is a protocol built on Solana that introduces ZK compression, a primitive that enables secure scaling directly on the L1.
Hyperscale state: Developers and users can opt to compress their on-chain state, reducing state costs by orders of magnitude while preserving the security, performance, and composability of the Solana L1.
A new design space for computation: In addition to classic on-chain compute, compressed state via Light natively supports custom ZK compute, enabling developers to build previously impossible computation designs on Solana.
In depth documentation for developers is provided at https://www.zkcompression.com.
| Creation Cost | Regular Account | Compressed Account |
|---|---|---|
100-byte PDA Account | ~ 0.0016 SOL | ~ 0.00001 SOL (160x cheaper) |
100 Token Accounts | ~ 0.2 SOL | ~ 0.00004 SOL (5000x cheaper) |
Minimal state cost | Securely stores state on cheaper ledger space instead of the more expensive account space, allowing apps to scale to millions of users. |
L1 security & performance | Execution and data availability on Solana, preserving the performance and security guarantees of the L1. |
Composable | Solana programs can mix and match between compressed and regular on-chain state, allowing atomic interaction with multiple programs, accounts, and compressed accounts. |
Custom ZK compute | Leverage Light's on-chain contracts and plumbing, and tap into global, unified ZK-friendly state. |
Compression: Only the state roots (small fingerprints of all compressed accounts) are stored in on-chain accounts. The underlying data is stored on the cheaper Solana ledger.
ZK: The protocol uses small zero-knowledge proofs (validity proofs) to ensure the integrity of the compressed state. This is all done under the hood. You can fetch validity proofs from RPC providers that support ZK Compression.
