# Sentinel SRB

DVPNSRB is a benchmark representing the mean, annualized staking rate across all active Sentinel validators.

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

> **TL;DR:** Sentinel staking rewards follow the Cosmos SDK formula (ATOMSRB): annual provisions plus annualized fees, minus community tax, divided by total staked DVPN 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.

### DVPN Validator Staking Rewards Rate: DVPNSRB(v)

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

$$
DVPNSRB(v) = ATOMSRB(v)

### DVPN Real Reward Rate: DVPNSRB^R

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

$$
DVPNSRB^R = ATOMSRB^R

**Inflation Rate Behavior**

* Sentinel inflation operates on a structured 6-month epoch system, with the inflation rate decreasing by 6% per epoch, similar to a halving mechanism. Starting with a 49% annual inflation at genesis, this rate continues to decrease until reaching a steady 13% annual inflation. Afterward, a per-block decay model will reduce inflation progressively toward zero, capping the supply at 48 billion tokens.

<table><thead><tr><th width="188">Metric</th><th>Description</th></tr></thead><tbody><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 total quantity of distinct delegations made. It doesn't distinguish based on unique delegator addresses and excludes considerations of any minimum delegation thresholds.</td></tr></tbody></table>
