🧪Zetachain SRB

The SRB reward rate for Zetachain SRB is a benchmark that represents the mean, annualized staking rate across all active ZETA validators.

Zetachain SRB is calculated and published by Staking Rewards via the Zetachain Asset profile and Staking Data API.

$$Zetachain SRB = 365 * ( bp / abt * 86400 + df ) * ( 1 - c t ) / st$$

Formula key	Metric name	Description
bp	Block Provision	Blocks Provision is calculated by "annual provisions / blocks_per_year", whereas the annual provision is recalculated by the Zetachain protocol each block according to inflation parameters, and the blocks_per_year is a constant parameter set by ZETA governance.
abt	Block Time	The average block time over the last 24 hours. Note, that this number often differs significantly from the expected block time.
df	Daily Fees	The total number of ZETA tokens paid as transaction fees in the last 24 hours.
ct	Community Tax	Community Tax is the percentage of inflation rewards and fees that are sent to the community pool at each block. The constant parameter is set by ZETA governance.
st	Staked Tokens	The total number of ZETA tokens bonded with active, non-jailed validators.

• Zetachain SRB takes into account all accumulated rewards, whether they have been claimed or remain unclaimed.

• Zetachain SRB operates on a non-compounded basis, meaning it excludes returns generated from the reinvestment of rewards.

• Zetachain SRB is based on an assumption of 100% validator efficiency. For a CSRR adjusted according to individual validator performance, please refer to CSRR(v).

Slashing

1. Zetachain SRB does not factor in the possibility of slashing occurrences.

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

Zetachain Validator Staking Rewards Rate: SRB(v)

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

$$SRB(v) = SRB * (1*p)*(1-cr)$$

Formula key	Metric name	Description
p	Performance	The percentage of successfully validated blocks over the last 10,000 assigned blocks for this validator.
cr	Commission Rate	The percentage commission rate the validator has set as a delegation fee for all delegators.

---

Observation Period:

1. The Zetachain SRB is determined based on the latest generated block at the point of evaluation.

2. 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

1. SRB 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.

Zetachain Real Reward Rate SRB(r)

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

$$SRB(r) = 1+SRB /(1+i)-1$$

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

1. Token Allocation and Unlocks: Zetachain has a total supply of 100m tokens, with various allocations for investors, community treasury, rewards treasury, and others.

Other metrics calculated by Staking Rewards:

Metric	Description
Delegated Tokens	The number of tokens delegated to validators
Self Staked Tokens	The number of tokens staked by validators directly.
Staking Wallets	This metric refers to the total quantity of distinct delegations made. It doesn't distinguish based on unique delegator addresses and excludes considerations of any minimum delegation thresholds.
Staking Ratio	Staking Ratio
Rewards per Year	Rewards per Year
