⚛️Cosmos Hub SRB

Cosmos Hub Staking Rewards Benchmark (ATOMSRB™) Methodology

ATOMSRB is a benchmark representing the mean, annualized staking rate across all active Cosmos validators.

ATOMSRB is calculated and published by Staking Rewards via the Cosmos Profile and Staking Data API.

Other assets utilizing Cosmos SDK, which Staking Rewards integrate, reference ATOMSRB for reward rate calculations. Some assets might introduce proprietary changes or include additional parameters. The differences are mentioned for calculations involving extra or modified variables.

ATOM Staking Rewards Rate: ATOMSRB

ATOMSRB = (ap + df * t_y) * (1 - ct) / st

Formula Key

Metric Name

Description

ATOMSRB takes into account all accumulated rewards, whether they have been claimed or remain unclaimed.
ATOMSRB operates on a non-compounded basis, meaning it excludes returns generated from the reinvestment of rewards.
ATOMSRB is based on an assumption of 100% validator efficiency. For a SRB Reward Rate adjusted according to individual validator performance, please refer to ATOMSRB(v).

Slashing

ATOMSRB 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.

Expected vs. Actual Block Time

The inflation metrics retrieved from RPC endpoints may not depict the genuine inflation rate. This discrepancy arises due to the actual block time being significantly quicker than the protocol's targeted time.
The difference between expected and actual block time influences the annual provisions which affects rewards.
Consequently, there's an elevation in blocks generated annually, leading to increased inflation.
The ATOMSRB methodology adjusts for this variation, prioritizing the actual block time over the anticipated block time to determine accurate inflation and reward rates.

Observation Period

The ATOMSRB 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

ATOMSRB excludes rewards accrued from Interchain/Replicated Security.
ATOMSRB 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.

ATOM Validator Staking Rewards Rate: ATOMSRB(v)

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

ATOM Real Reward Rate: ATOMSRB^R

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

Inflation Rate Behavior

The inflation is also subject to a rate change (positive or negative) depending on the distance from the desired ratio (67%). The maximum rate change possible is defined to be 13% per year, however the annual inflation is capped as between 7% and 20%.
