Crust provides a decentralized storage network for the Web3 ecosystem. Crust is based on Polkadot Substrate technology framework and will serve as Polkadot's decentralized storage parallel chain. Crust is a member project of the Web3 Bootcamp and Substrate Builders Program and was granted a Grant by the Web3 Foundation.

Crust supports multiple storage tier protocols, such as IPFS and FastDFS. Crust's Meaningful Proof of Work mechanism (MPoW) uses trusted Execution Environment (TEE) technology to reliably prove a node's storage workload. Crust's Proof of Interest agreement (GPoS) is a PoS agreement that adds a guarantee mechanism.

The native token CRU in the Crust network is a functional token that represents the value of the entire network. It's like ETH in Ethereum or DOT in Boca.
1. Maintaining GPoS consensus on Crust networks,
2. Used to guarantee the selected node
3. As contractual guarantee and commission for the provision of resource services
4. 5. Can be used to purchase resource services. Can be used to campaign and vote on on-chain governance mechanisms and vote on proposals.
