# Key Components

Kaisar Network mainly comprises of four components:

1. **Kaisar Cloud (End-Users):** End-users seek to rent GPUs within the Kaisar Network, directly engaging with the blockchain to access GPU rental, payment processing, and cancellation services.
2. **Providers:** Providers offer GPU computing resources and report their status back to the PEAQ Blockchain, receiving rewards for their contributions.
3. **PEAQ Blockchain:** Kaisar leverages PEAQ Blockchain, a multi-chain layer one blockchain specifically designed and optimized for DePIN. It supports more than 100,000 transactions per second (TPS) and has a minimal transaction cost. PEAQ enables seamless interaction with Polkadot, Cosmos, Solana, Binance, and Ethereum through Wormhole.
4. **Kaisar Checkers:** Kaisar Checkers ensure the integrity and functionality of the resources by performing checks and providing Proof of Physical Work, also earning rewards from the PEAQ Blockchain.
