APT Staking Rewards Benchmark (APTSRB™) Methodology
APTSRB is a benchmark representing the mean, annualized staking rate across all active Aptos validators.
APTSRB is calculated and published by Staking Rewards via the Aptos Profile and Staking Data API.
| Formula key | Metric name | Description |
|---|---|---|
rrpe | Reward rate per Epoch | This is a value determined by the protocol, and it represents how many tokens a validator gets per staked APT, per epoch (assuming 100% performance) |
epy | Epochs per Year | How many epochs there are in a year. Currently, epchs last approximately 7200s (2 hours) |
Slashing
Currently, slashing is not implemented in the Aptos Network
APT Validator Staking Reward Rate: APTSRB(v)
Staking Rewards calculates the APTSRB for each validator based on their individual performance and commission rate.
| Formula key | Metric name | Description |
|---|---|---|
c | Commission | The fee imposed by a specific validator to its delegators. |
p | Performance | This metric is determined by the ratio between number of successful proposals by the validator and the total number of proposals made by the validator |
Observation Period:
The APTSRB is determined based on the latest generated block at the evaluation point.
This data is then annualized for a comprehensive year-long projection.
Calculation
The calculation happens every 2 hours and is immediately published via Staking Data API.
Limitations
APTSRB employs a 365-day convention for annualizing current slot times. This convention remains consistent and does not accommodate adjustments for leap years.
APT Real Reward Rate: APTSRB^R
The real reward rate calculates the APTSRB adjusted for inflation in the network.
| Formula key | Metric name | Description |
|---|---|---|
ir | Inflation Rate | The annual rate at which supply increases. This value is equal to the annual emissions. |
Other Aptos metrics calculated by Staking Rewards:
| Metric | Description |
|---|---|
Delegated Tokens | The number of APT tokens delegated to validators. |
Self Staked Tokens | The number of APT tokens staked by validators directly. |
Staking Wallets | Total number of unique delegations onchain. It doesn't distinguish based on unique delegator addresses. |
