FLOW Staking Rewards Benchmark (FLOWSRB™) Methodology

FLOWSRB is a benchmark representing the mean, annualized staking rate across all active Solana validators.

FLOWSRB is calculated and published by Staking Rewards via the Flow Profile and Staking Data API.

$$FLOWSRB = tr * (sn/st)$$

Formula key	Metric name	Description
tr	Total staking rewards	Total staking rewards to be paid out during the current epoch
st	Staked Tokens	Sum of all the FLOW staked by all the participants in the network.
sn	Self Staked	Amount of FLOW Staked by the target user for the current Epoch

Slashing

• FLOWSRB does not factor in the possibility of slashing occurrences.

• It's important to note that if validator entities face slashing, rewards will increase, as the slashed tokens are reallocated among validators.

FLOW Validators Staking Reward Rate: FLOWSRB(v)

Staking Rewards calculates the FLOWSRB for each validator based on their individual performance and commission rate.

$$SQDSRB(v) = FLOWSRB * (1-cr)$$

Formula key	Metric name	Description
cr	Commission Rate	The percentage commission rate the validator has set as a delegation fee for all delegators

Observation Period:

• The FLOWSRB is determined based on the latest generated epoch 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

• FLOWSRB excludes rewards accrued from on-chain fees.

• FLOWSRB employs a 365-day convention for annualizing current slot times. This convention remains consistent and does not accommodate adjustments for leap years.

FLOW Real Reward Rate: FLOWSRB^R

The real reward rate calculates the FLOWSRB adjusted for inflation in the network.

$$FLOWSRB^R=1 + FLOWSRB/(1+ir) -1$$

Formula key	Metric name	Description
ir	Inflation Rate	The annual provisions divided by the circulating supply.

Inflation Rate Behavior

• Starting from February 2, 2021, the inflation rate of FLOW is set at 5% annually

Other Flow metrics calculated by Staking Rewards:

Metric	Description
Delegated Tokens	The number of FLOW tokens delegated to workers.
Self Staked Tokens	The number of FLOW tokens bonded by workers directly.
Staking Wallets	The total number of unique delegations on-chain. It doesn't distinguish based on unique delegator addresses.

Data Sources:

• Staking Rewards from indexed FLOW Blockchain RPC Endpoints
