Reward Distribution Rules

Every 5 days, we will count the points earned during that period of time and distribute rewards proportionately.

In order to receive rewards from the testnet, you need to go to Crust APPS where you can bond your ETH account to your Crust controller account. The rewards will go to your ETH account in the form of ERC20. The bonding procedures are shown as follows:

Every five days we will count the points of the past five days and distribute rewards in proportion.The total reward pool is approximately 300,000 CRUs, of which 50% are CRUs that are transferrable, and the remaining 50% are CRU18. CRU18 is initially locked and will be unlocked monthly within 18 months after the mainnet launch.

Point-earning Rules

NOTES: The rules are to be finalized by the announcement from Crust development team. Please stay tuned for the latest announcement to keep up-to-date with any change.

During the test period, points will be counted and summed in each Era based on three indicators of nodes: 1) validator rate, 2) success rate of reporting work report, and 3) overall storage capacity. Point-earning rules in each Era are as follows:

Points = storage_capacity * (1 + validator_rate * validator_multiplier) * work_report_multiplier

• storage_capacity: Storage capacity of the current era

• validator_rate: the number of Era when the node is a validator / the total number of Era since the node joining the network

• validator_multiplier:

  Wickedness rate	Validator multiplier
  < 1%	0.5
  < 1.2%	0.3
  < 1.4%	0.1
  < 1.6%	-0.1
  > 2%	-0.3

• work_report_multiplier:

  Success rate of reporting work report	Work report multiplier
  > 99%	1
  > 98%	0.9
  > 97%	0.8
  > 95%	0.7
  < 95%	0.5
