🏝️Solana SRB
SOL Staking Rewards Benchmark (SOLSRB™) Methodology
SOLSRB is a benchmark representing the mean, annualized staking rate across all active Solana validators.
SOLSRB is calculated and published by Staking Rewards via the Solana Profile and Staking Data API.
| Formula key | Metric name | Description |
|---|---|---|
ir | Inflation Rate | The annual rate at which supply increase. It was initiated at a rate of 8% in February 2021 and is expected to decline by 15% annually until reaching a steady state of 1.5%. |
est | Expected Slot Time | The theoretical time proposed by the consensus. |
stAvg30d | 30 Day Average of Slot Time | Average real slot time over the last 30 days. |
ss | Staked Supply | Number of Self-Staked and Delegated tokens to Solana Validators. |
ts | Total Supply | All Solana tokens minted minus all Solana tokens burnt. |
Slashing
SOLSRB does not factor in the possibility of slashing occurrences.
There is no token slashing implemented at this stage.
SOL Validator Staking Reward Rate: SOLSRB(v)
Staking Rewards calculates the SOLSRB for each validator based on their individual performance and commission rate.
| Formula key | Metric name | Description |
|---|---|---|
vrpe | Validator Rewards per Epoch | Based on the validator performance history, it is possible to determine it's rewards for the epoch. |
vss | Validator Staked Tokens | The sum of Self-staked tokens and the Delegated tokens for a specific validator. |
epy | Epochs per Year | Based on the slot and epoch times, we derive the number of estimated epochs in a year. |
c | Commission | The fee imposed by a specifici validator to it's delegators |
Observation Period:
The SOLSRB 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
SOLSRB excludes rewards accrued from onchain fees.
SOLSRB employs a 365-day convention for annualizing current slot times. This convention remains consistent and does not accommodate adjustments for leap years.
SOL Real Reward Rate: SOLSRB^R
The real reward rate calculates the SOLSRB adjusted for inflation in the network.
| Formula key | Metric name | Description |
|---|---|---|
ir | Inflation Rate | The annual rate at which supply increase. It was initiated at a rate of 8% in February 2021 and is expected to decline by 15% annually until reaching a steady state of 1.5%. |
Other Solana metrics calculated by Staking Rewards:
| Metric | Description |
|---|---|
Delegated Tokens | The number of SOL tokens delegated to validators. |
Self Staked Tokens | The number of SOL tokens staked by validators directly. |
Staking Wallets | Total number of unique delegations onchain. It doesn't distinguish based on unique delegator addresses. |
