| Protocol time | Human readable time | |
|---|---|---|
Protocol time 1 | Block | 1 second |
Protocol time 2 | Epoch | 8 minutes |
First reward delay | 1 epoch | 8 minutes |
Reward frequency | Every epoch | 8 minutes |
Unbonding period | 7 days | 7 days |
The protocol does not have a fixed epoch time. Epoch times can fluctuate depending on network conditions.
For fluid rewards, stake is locked for a predetermined staking duration (from 2 weeks up to 1 year) selected by the staker.
Fluid rewards are distributed all at once at the end of the staking duration.
Minimum stake amount | ✅ | 1 FTM |
Partial stake changes | ❌ | |
Partial reward withdrawal | ❌ | |
Compounding | ❌ | |
Penalty | ❌ | |
Slashing | ✅ | Double signing - Up to 100% |
Stakers can choose to earn base rewards (stake-as-you-go) or fluid rewards.
Stakers can get started with base rewards by delegating without selecting a staking duration. Rewards are distributed and available to be claimed every epoch.
To get fluid rewards, stakers must select a staking duration from 2 weeks to 1 year. More rewards are earned by locking up longer. Rewards are not distributed until the end of the staking duration.
Stakers choosing fluid rewards can request to unstake before the staking duration ends. However, rewards will be reduced to half of base rewards.
For example, let’s assume the protocol has a base reward rate of 1.8% and fluid reward rate (at maximum staking duration) of 6%. A staker has staked 1,000 FTM and selected the maximum staking duration which would give them a 6% reward rate at the end of 365 days. Halfway through the staking duration, the staker decided to unstake. After an unbonding period of 7 days, the protocol will provide only 4.5 FTM as rewards, a 0.9% reward rate, effectively half of the base reward rate.
Rewards come from newly issued tokens and transaction fees.
Fixed issuance of tokens. Approximately 2.67 FTM is issued per block. Newly issued tokens are distributed as rewards to stakers.
Transaction fees. 70% of transaction fees are distributed to stakers as rewards. 15% goes to ecosystem applications, 10% goes to an ecosystem support vault and the remaining 5% gets burned.
Factors that impact realized rewards.
Validator performance. Rewards coming from new issued tokens will exponentially decrease by a validator’s downtime. Rewards coming from transaction fees will linearly decrease by a validator’s downtime.
Staking duration will impact realized rewards. Stakers have the option to stake from 2 weeks to 1 year. More rewards are earned by locking up longer.
Commissions. Commissions for validators are fixed at 15%.
Rewards coming from new issued tokens will exponentially decrease by a validator’s downtime. Rewards coming from transaction fees will linearly decrease by a validator’s downtime.
Slashing can occur for any double signing validator. The offending validator and its delegators’ entire stake can be deducted.
A validator is kicked out of the active set if it has a downtime longer than 72 hours.
Total validator cap | ❌ | |
Validator requirements | ✅ | 50,000 FTM |
A validator can have up to 15 times their self-staked amount as delegations. For example, if a validator has self-stake of 1,000,000 FTM, it can get up to 15,000,000 FTM in delegations.
Commissions for validators are fixed at 15%.
