The Collator system has its own running cycle, 600 blocks in a round, each round takes about 2 hours, and the cycle is related to the operations of reward settlement, addition, and unbonding.
- Collator: Collator runs a full node on Bifrost parachain and Kusama relay-chain, and produce the state transition proof for relay chain validators.
- Active set: A set of Collators who can receive commission by producing blocks, choosen by the ranking of delegating amount.
- Candidates: Collators who out of Active set.
- Collator self bond: Self-bond as a minimum BNC to be a Collator, continue self-bond same as delegating.
- Delegator: Bifrost token holders who stake tokens, vouching for specific collator candidates on the parachain.
- Delegate: Bond BNC Token for Bifrost Collators, receiving delegating rewards depends on the rank of Collator and delegating amount.
- Maximum number of active Collators and candidates
- Bonding parameters (Collator)
- Bonding parameters (Delegator)
Bifrost network reserved 5% (4,000,000 BNC) of total issurance to incentivize Collator mechanism for 5 years (800,000 BNC/year), with no inflation. The reward for each Round is a fixed 180 BNC. The reward calculation method is as follows.
According to the incentive ratio, the reward for each block is:
180/600*10% = 0.03 BNC
180/600*90% = 0.27 BNC
If a collector's total delegating amount is 100,000 BNC and it is in the 64 Active Collator set for the whole year, the average revenue of the Collator is:
800,000 x 10% / 64 = 1,250 BNC
Self-bond delegating Reward:
800,000 x 90% / 64 x 5,000/100,000 = 562.5 BNC
1,250 + 562.5 = 1,812.5 BNC
1,812.5/5,000 = 36.25%
