  • Collators. The protocol is a parachain of Polkadot. It relies on Polkadot for network security. It maintains a set of validators called collators, who propose blocks candidates and produce state transition proofs for Polkadot validators.

  • Transaction fees. 20% of transaction fees are sent to the protocol treasury. The remaining transaction fees are burned.

  • Reward payout. Reward payout starts from the 2nd block to the 73rd block of a new round. For each block, one validator and its delegators are selected to be paid rewards.


  • Rewards come from newly issued tokens.

    • Fixed inflation rate applied to total token supply. The protocol issues 5% of the total token supply on an annual basis. 20% of this gets distributed to validators as commissions. 30% is allocated as a bond reserve to remain a parachain of Polkadot. The remaining 50% gets distributed amongst both validators and delegators according to their stake.

  • Factors that impact realized rewards.

    • Validator performance. Validators earn rewards based on total blocks proposed in each round.


  • The protocol does not have any penalties or slashing.


Total validator cap


Validator requirements

20,000 GLMR

  • A validator needs 10,000 GLMR of self-stake to become a validator candidate. The validator also needs 10,000 GLMR of bond to register their account to receive rewards.

  • Commissions for validators are fixed at 20%. 20% of newly issued tokens are automatically distributed to validators.
