Overview

What is ZK Compression?

ZK Compression is a new primitive built on Solana that enables secure scaling directly on the L1.

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.

State cost reduction

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)

Core Features

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.

How to use this Documentation

This documentation provides a high-level introduction to the ZK Compression primitive and is a directory guiding you to relevant codebases, examples, and advanced guides.

The ZK Compression primitive is being built in the open, and a public Testnet will soon be available. Stay up to date with the core teams contributing to ZK Compression and its RPC implementation: Light and Helius Labs.
