# Welcome to ZK Compression
> ZK Compression is a Solana account primitive that lets you create tokens and PDAs without rent-exemption with L1 performance and security.
| **Creation Cost** | Solana | ZK Compression |
| :---------------- | :------------------- | :-------------------- |
| **Token Account** | \~2,000,000 lamports | \~**5,000** lamports |
| **100-byte PDA** | \~1,600,000 lamports | \~**15,000** lamports |
## Features
{" "}
High performance token standard that uses ZK Compression under the hood. For
Defi and Payments.
For App State.
For Token Distribution.
## Quickstart
Install packages in your working directory:
```bash theme={null}
npm install @lightprotocol/stateless.js@alpha \
@lightprotocol/compressed-token@alpha
```
Install the CLI globally:
```bash theme={null}
npm install -g @lightprotocol/zk-compression-cli@alpha
```
Install packages in your working directory:
```bash theme={null}
yarn add @lightprotocol/stateless.js@alpha \
@lightprotocol/compressed-token@alpha
```
Install the CLI globally:
```bash theme={null}
yarn global add @lightprotocol/zk-compression-cli@alpha
```
Install packages in your working directory:
```bash theme={null}
pnpm add @lightprotocol/stateless.js@alpha \
@lightprotocol/compressed-token@alpha
```
Install the CLI globally:
```bash theme={null}
pnpm add -g @lightprotocol/zk-compression-cli@alpha
```
## What is ZK Compression?
ZK Compression is a framework that reduces the storage cost of Solana accounts by combining generalized state compression and zero-knowledge proofs.
Normally data is stored in millions of on-chain accounts. State compression stores account data on the{" "}
Solana ledger
. Only a fingerprint is stored on-chain for cryptographic security - a hash of all compressed accounts. This hash allows transactions to use the account data inside Solana's virtual machine as if it were stored on-chain.
The protocol uses 128 byte zero-knowledge proofs (validity proofs) to verify the integrity of the compressed accounts. By default, this is all done under the hood. You can fetch validity proofs from RPC providers that support ZK Compression.
