⚜️Hedera SRB
HBAR Staking Rewards Benchmark (HBARSRB™) Methodology
HBARSRB is a benchmark representing the mean, annualized staking rate across all active ZETA validators.
HBARSRB is calculated and published by Staking Rewards via the Hedera Profile and Staking Data API.
| Formula key | Metric name | Description |
|---|---|---|
dr | Daily Rewards | Fix reward rate per staked HBAR per day. |
df | Daily Fees | The total number of HBAR tokens paid as transaction fees on the network. |
st | Staked Tokens | The total number of tokens that are currently being staked across Hedera. |
Year Constant | 365d |
HBARSRB takes into account all accumulated rewards, whether they have been claimed or remain unclaimed.
HBARSRB operates on a non-compounded basis, meaning it excludes returns generated from the reinvestment of rewards.
HBARSRB is based on an assumption of 100% validator efficiency. For a HBARSRB adjusted according to individual validator performance, please refer to HBARSRB(v).
Slashing
Although Hedera Hashgraph operates as a PoS system, it does not involve slashing or bonding, so nodes do not face the related loss of liquidity.
Hedera Validator Staking Rewards Rate: HBARSRB(v)
Staking Rewards calculates the HBARSRB for each validator based on their individual performance and commission rate.
| Formula key | Metric name | Description |
|---|---|---|
p | Performance | The percentage of successfully validated blocks. |
cr | Commission Rate | The percentage commission rate the validator has set as a delegation fee for all delegators. |
Observation Period:
HBARSRB is determined based on the latest generated block at the point of evaluation.
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
HBARSRB employs a 365-day convention for annualizing current block provisions and daily fees. This convention remains consistent and does not accommodate adjustments for leap years.
HBAR Real Reward Rate (HBARSRB^R)
The real reward rate calculates the HBARSRB adjusted for inflation in the network.
| Formula key | Metric name | Description |
|---|---|---|
i | Inflation Rate | The annual provisions adjusted by the actual block time of the last 24h and divided by the total token supply in the network. |
Inflation Rate Behaviour
The release of HBAR tokens into circulation is controlled by a predefined schedule.
