Question 1

What is CRU?

Accepted Answer

CRU is the primary utility token of Crust Network. It is not used for only one operation; it connects network consensus, collateral for node or resource services, on-chain transaction fees, resource-service purchases, and on-chain governance. These uses involve different participants: network participants may lock CRU as collateral for consensus or nodes; storage users use it to purchase services and pay order-related fees; service providers may need to post a deposit; and governance participants use it to take part in elections and proposal voting.

Question 2

What is the relationship between GPoS and CRU staking?

Accepted Answer

CRU can be used to maintain Crust's GPoS consensus. The core relationship is that a party participating in network maintenance provides economic collateral by staking CRU, making CRU one of the staking assets listed for this consensus mechanism. This differs from paying a transaction fee: a transaction fee is a cost paid when initiating an on-chain operation, whereas staking locks or collateralizes assets for network participation. The current source confirms CRU's use in GPoS staking, but does not provide personal participation thresholds, reward formulas, unlock waiting periods, or specific penalty parameters on that page.

Question 3

How is CRU used for Crust storage orders?

Accepted Answer

Crust's decentralized storage market (DSM) connects users who need storage with merchants that provide storage capacity. Users first pay a certain fee to initiate a storage order; after the order is accepted by a merchant, member nodes of its Group are responsible for storing the file and providing retrieval services. Order fees are not fixed. Official documentation states that they adjust dynamically with storage resources, on-chain state resources, and throughput resources in the network; users may also pay a small additional fee to accelerate order processing. Therefore, a user's final cost depends on resource conditions, order requirements, and whether expedited processing is selected, rather than only on the single factor of a file existing.

Question 4

What practical effect does locking CRU have for storage users?

Accepted Answer

Storage users can lock CRU as storage-market collateral to receive discounts on storage orders. The direct object of this mechanism is order fees: users do not automatically receive discounts merely by holding CRU; they need to use CRU in the storage-market collateral arrangement. A discount does not mean that all storage costs are waived, nor does it mean that locking CRU generates fixed returns. The specific discount level, locked amount, and applicable conditions are subject to the storage market's rules in effect at the time.

Question 5

Why do storage service providers need CRU collateral?

Accepted Answer

A Group Owner node can register as a storage merchant on behalf of its Group and must post a certain deposit when registering. The deposit enables the merchant to receive DSM orders; member nodes of that Group then actually perform file storage and retrieval. After a file is successfully stored, the merchant can receive the corresponding storage revenue from DSM. Official documentation also states that valid data increases a node's effective staking quota, which may help the node obtain higher staking rewards; this relationship depends on successful file storage and the applicable staking-quota rules, rather than resulting directly from merely posting a deposit.

Question 6

What is the difference between CRU node collateral and resource-service guarantee deposits?

Accepted Answer

CRU can serve as collateral for selected nodes and as a guarantee deposit when providing resource services. Both uses provide economic collateral for participation roles, rather than being direct payment by a user for a one-time service. Node collateral concerns the guarantee requirements for a node's participation in the network after it is selected; resource-service guarantee deposits concern the provision of resource services. Both are alongside CRU's transaction-fee and storage-order payment uses, but their service targets and triggering scenarios differ.

Question 7

Why is CRU used when operating on Crust Network?

Accepted Answer

CRU is one of the transaction-fee assets used when operating Crust Network. When a user initiates an operation requiring on-chain processing, the transaction fee is the cost paid for the network to process that operation. It is related to, but not the same concept as, order fees for purchasing storage resources. Storage order fees cover resources such as storage, state, and throughput and adjust dynamically, whereas transaction fees correspond to on-chain transaction processing. A storage-related operation may involve both an order's resource fee and the transaction fee for an on-chain operation; whether they occur and their amounts depend on the operation performed and the rules in effect at the time.

Question 8

Can CRU participate in network governance?

Accepted Answer

CRU can be used for elections and proposal voting in on-chain governance. This use brings the token into the network decision-making process: participants meeting the governance rules in effect at the time can use CRU to participate in elections or vote on on-chain proposals. “Able to participate in governance” does not mean holders necessarily have equal weight in every decision, nor does it mean every proposal will pass. Voting eligibility, weighting methods, proposal processes, and final execution are all determined by the governance mechanism in effect at the time.
