🫐Avail SRB

Avail Staking Rewards Benchmark (AVAILSRB™) Methodology

AVAILSRB is a benchmark representing the annualized staking rate for the AVAIL token.

AVAILSRB is calculated and published by Staking Rewards via the Avail Profile and Data API.

AVAIL Staking Rewards Rate: AVAILSRB

$$AVAILSRB = evr * t_y / st$$

Formula Key	Metric Name	Description
evr	Era Validator Reward	The total reward distributed to all validators for the previous era, sourced directly from on-chain storage.
st	Staked Tokens	The total staked AVAIL in the active era, sourced from on-chain era total stake.
$t_y$	Year Constant	365 eras — used to annualize the per-era reward (24-hour eras).

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

• The reward rate is derived from actual on-chain era rewards, not from an inflation model estimate.

• Both claimed and unclaimed rewards are included.

Slashing

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

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

AVAIL Validator Staking Rewards Rate: AVAILSRB(v)

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

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

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

AVAIL Real Reward Rate: AVAILSRB^R

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

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

Formula key	Metric name	Description
ir	Inflation Rate	Derived from on-chain era rewards: eraValidatorReward * 365 / totalSupply.

Inflation Rate Behavior

• Avail's inflation is derived from actual on-chain era rewards. The protocol distributes AVAIL tokens to validators and nominators based on their staked amounts through controlled token supply growth.

---

Other Avail metrics calculated by Staking Rewards:

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