# Nimiq SRB

NIMIQSRB is a benchmark representing the mean, annualized staking rate across all active Nimiq validators.

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

> **TL;DR:** Nimiq staking rewards come from a supply-decay emission model that approaches a 21 billion NIM maximum supply asymptotically. The reward rate equals the predicted new supply over 365 days divided by total staked NIM.

$$
NIMIQSRB = (fs - cs) / st
$$

<table data-full-width="false"><thead><tr><th width="141">Formula key</th><th width="158">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>fs</td><td>Predicted Future Supply</td><td>The predicted total supply 365 days from now, calculated using Nimiq's supply-decay emission model with decay constant 0.9999999999960264.</td></tr><tr><td>cs</td><td>Current Supply</td><td>The current total supply of NIM, derived from the supply-decay model using genesis time 2024-11-19T16:00:00Z and initial supply of 12,893,109,654.06244 NIM.</td></tr><tr><td>st</td><td>Staked Tokens</td><td>Total staked NIM sourced from the Nimiq network supply data.</td></tr></tbody></table>

* NIMIQSRB represents an APY value derived directly from the supply-decay emission model.
* The supply-decay model approaches a maximum supply of 21 billion NIM asymptotically.

#### Slashing

1. If a validator is found to be misbehaving, the validator will be punished. There are various severities of punishment, from taking away their block reward, slashing part of their stake, all the way to on-chain jail.

### NIM Validator Staking Reward Rate: NIMIQSRB(v)

Staking Rewards calculates the NIMIQSRB for each validator based on their individual commission rate.

$$
NIMIQSRB(v) =  NIMIQSRB \* (1 - c)
$$

<table data-full-width="false"><thead><tr><th width="150.33333333333331">Formula key</th><th width="187">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>c</td><td>Commission</td><td>The fee imposed by a specific validator to its delegators.</td></tr></tbody></table>

***

#### Observation Period:

1. The NIMIQSRB is determined based on elapsed time since the genesis block (2024-11-19T16:00:00Z) and the supply-decay model.
2. This data projects forward 365 days for the annual reward estimate.

#### Calculation

The calculation happens every 2 hours and is immediately published via [Data API](https://www.stakingrewards.com/data-api).

#### Limitations

1. NIMIQSRB employs a 365-day convention for projecting future supply. This convention remains consistent and does not accommodate adjustments for leap years.

### NIM Real Reward Rate: NIMIQSRB^R

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

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