Crust is a decentralized storage network in the Web3 ecosystem, built on Polkadot's Substrate framework. It will be launched as a decentralized storage Parachain of Polkadot. Crust is a member of the Web3 Bootcamp and Substrate Builders Program, and has received a Web3 grant from the Web3 Foundation. It supports multiple storage layer protocols such as IPFS and FastDFS. The native token CRU is a utility token that represents the value of the entire network, similar to ETH in Ethereum or DOT in Polkadot. The CSM token is Crust Shadow's original token, which will be allocated to the community. CSM can be used for various purposes such as staking, guaranteeing nodes, providing recourse services, transaction fees, purchasing resource services, participating in governance mechanisms, privacy encryption, data exchange and trading, and participating in Maxwell's storage market activities. Users can also use CSM to obtain discounts and exchange it for CRU in Maxwell's market revenue pool in the future.
