Advanced topics

Rewards

• Rewards come from newly issued tokens and transaction fees.

  • Inflation rate applied to total token supply. Inflation rate ranges between 12.5% and 25% depending on the actual staking ratio to target staking ratio. The rate increases when actual staking ratio is below target staking ratio and vice-versa. The target staking ratio for Persistence is 67%. 10% of the newly issued tokens is sent to the community pool and the rest is sent to stakers as rewards.

• Factors that impact realized rewards.

  • Commissions.

Risks

• Penalty. A validator that fails to be online for 5,000 blocks out of the most recent 10,000 blocks will be considered offline. Stakers of an offline validator will be penalized and lose 0.01% of their stake. The offline validator will kicked off the active validator set and will be able to join after 10 minutes has passed.

• Slashing. A validator that attests to two different blocks will be slashed. Stakers of a slashed validator will lose 5% of their stake. The slashed validator will be indefinitely kicked off the active validator set and will need to create a new validator.
