Crust provides a decentralized storage network of Web3 ecosystem. It is developed based on Polkadot’s Substrate technical framework, and will be launched as decentralized storage parachain of Polkadot. Crust is member of Web3 Bootcamp and Substrate Builders Program, and ha received Web3 grant from Web3 Foundation. Crust supports multiple storage layer protocols such as IPFS and FastDFS. Crust’s MPoW (Meaningful Proof of Work) leverages TEE technologies to generate proof of Nodes’ storage work reliably. Its GPoS is derived from PoS consensus, with adding the guarantee mechanism and process. The native token CRU is a utility token representing the value of the entire network, similar to ETH in Ethereum or DOT in Polkadot. CRU tokens has following functions: 1. Staking to maintain the GPoS consensus of the network 2. Used to guarantee the selected nodes 3. Serving as contract collateral and commission for providing resource services 4. Serving as a transaction fee for using the network 5. Used to purchase resource services 6. Used for election and voting of on-chain governance mechanism, and vote on proposals
