CRU is a cryptocurrency that operates on the Crust Network, a decentralized storage network that allows users to store and share data securely. The network is built on the Polkadot ecosystem, which enables interoperability between different blockchains. CRU is used as the native token on the Crust Network and is used to pay for storage and retrieval of data on the network.

One of the key features of CRU is its ability to incentivize users to contribute to the network by providing storage space. Users who contribute storage space are rewarded with CRU tokens, which can be used to pay for storage or traded on cryptocurrency exchanges. This incentivizes users to contribute to the network and helps to ensure that there is always enough storage space available for users who need it. Additionally, the use of a decentralized storage network like Crust helps to ensure that data is stored securely and is not subject to censorship or control by any central authority.
