Vara Staking Rewards Benchmark (VARASRB™) Methodology

VARASRB is a benchmark representing the annualized staking rate for the VARA token.

VARASRB is calculated and published by Staking Rewards via the Vara Profile and Data API.

VARA Staking Rewards Rate: VARASRB

$$VARASRB = roi$$

Formula Key	Metric Name	Description
roi	Return on Investment	The annualized staking reward rate published by the Vara network stats API, reflecting the current expected return for stakers.

• VARASRB is non-compounded, excluding returns from reinvestment of rewards.

• The reward rate is sourced from the Vara network's own stats endpoint, which computes the ROI based on current network parameters including era rewards, staking ratio, and validator performance.

• Both claimed and unclaimed rewards are included.

Slashing

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

• Vara implements Substrate's standard slashing mechanism. Validators can be slashed for equivocation or prolonged unresponsiveness.

VARA Validator Staking Rewards Rate: VARASRB(v)

Staking Rewards calculates the VARASRB for each validator based on their individual era points (performance) and commission rate.

$$VARASRB(v) = (vep / tep * tvr) / t_m * t_y / vst$$

Formula key	Metric Name	Description
$vep$	Validator Era Points	Validator era points accumulated in the observation period.
tep	Total Era Points	Total era points for all validators in the observation period.
tvr	Total Validator Rewards	All rewards distributed to all validators in the observation period.
vst	Validator Staked Tokens	Validator staked tokens, self-staked and nominated.
$t_y$	Year Constant	365d
$t_m$	Month Constant	30d

---

Observation Period:

1. The VARASRB is determined based on the latest completed era at the evaluation point.

2. This data is then annualized for a comprehensive year-long projection.

Calculation

The calculation happens every 6 hours and is immediately published via Data API.

Limitations

1. VARASRB employs a 365-day convention for annualizing era reward data. This convention remains consistent and does not accommodate adjustments for leap years.

VARA Real Reward Rate: VARASRB^R

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

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

Formula key	Metric name	Description
ir	Inflation Rate	Derived from on-chain era rewards: eraValidatorReward * 2190 / totalSupply.

Inflation Rate Behavior

• Vara uses 4-hour eras (2190 per year). The inflation rate is derived from actual on-chain era rewards, reflecting the real-time token emission of the network. Vara's inflation model distributes rewards to validators and nominators through the standard Substrate NPoS staking mechanism.

---

Other Vara metrics calculated by Staking Rewards:

Metric	Description
Delegated Tokens	The number of VARA tokens nominated to validators.
Self Staked Tokens	The number of VARA tokens staked by validators directly.
Staking Wallets	Total number of nominators on-chain.
