# BitSong SRB

Learn how BitSong staking rewards are calculated. BTSGSRB uses the Cosmos SDK formula with annual provisions, fees, community tax, and staked BTSG tokens.

BTSGSRB is a benchmark representing the mean, annualized staking rate across all active BitSong validators.

BTSGSRB is calculated and published by Staking Rewards via the [BitSong Profile](https://www.stakingrewards.com/asset/bitsong) and [Data API](https://www.stakingrewards.com/data-api).

> **TL;DR:** BitSong staking rewards follow the Cosmos SDK formula (ATOMSRB): annual provisions plus annualized fees, minus community tax, divided by total staked BTSG tokens. Validator-level rates factor in performance and commission.

{% hint style="info" %}
The calculations are derived from the ATOMSRB documentation, serving as the foundational reference to ensure the accuracy of relevant metrics.

### BTSG Validator Staking Rewards Rate: BTSGSRB(v)

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

$$
BTSGSRB(v) = ATOMSRB(v)

### BTSG Real Reward Rate: BTSGSRB^R

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

$$
BTSGSRB^R = ATOMSRB^R

**Inflation Rate Behavior**

* Nominal inflation is set by the Cosmos SDK `mint` module. It rises while the bonded ratio is below the goal of 67% (`goal_bonded` = 0.67) and falls above it, by at most 13% per year (`inflation_rate_change` = 0.13).
* Nominal inflation is bounded between 7% (`inflation_min`) and 10% (`inflation_max`). Both are governance parameters; the calculation reads annual provisions live and does not depend on the bounds.
* As of 10/09/2026 only \~27% of the supply is bonded (\~58.2M of \~215.8M BTSG), far below the 67% goal, so nominal inflation sits at the 10% cap.
* Blocks are produced slower than the `blocks_per_year` target of 5,733,820 (\~5.6s vs \~5.5s per block). Realised issuance, after the ATOMSRB block-time adjustment, is therefore \~9.8% of supply per year, below the nominal 10%. This is the opposite of Cosmos Hub, where faster blocks put realised issuance above nominal.
* The inflation rate is annual provisions divided by the total on-chain BTSG supply (bank supply of `ubtsg`), as in ATOMSRB.
* Rewards accrue only to bonded stake. As of 10/09/2026, \~28.8M BTSG (\~33% of all staked BTSG) is delegated to unbonded or unbonding validators, mostly jailed, and earns nothing; it is excluded from the BTSGSRB denominator, which uses bonded stake only.
* With inflation at the cap, BTSGSRB moves inversely with bonded stake: \~25.7% in June 2025 with \~70M BTSG bonded, \~35.6% in October 2026 with \~58M BTSG bonded. No single reward rate should be read as fixed.

### Other BitSong metrics calculated by Staking Rewards

<table><thead><tr><th width="188">Metric</th><th>Description</th></tr></thead><tbody><tr><td>Fee Revenue</td><td>The Fee Revenue reflects the annualized transaction fees, derived from the fees accumulated within the last 24 hours, evaluated at the prevailing USD rate.</td></tr><tr><td>Delegated Tokens</td><td>The number of tokens delegated to validators.</td></tr><tr><td>Self Staked Tokens</td><td>The number of tokens staked by validators directly.</td></tr><tr><td>Staking Wallets</td><td>This metric refers to the number of unique delegator addresses with at least one delegation on-chain. An address delegating to several validators is counted once. It excludes considerations of any minimum delegation thresholds.</td></tr></tbody></table>
