# Moonriver SRB

MOVRSRB is a benchmark representing the annualized staking rate for the MOVR token.

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

> **TL;DR:** Moonriver staking rewards are based on the average APR across all active collators in the Delegated Proof of Stake parachain model. Collators produce blocks and share rewards with delegators.

### MOVR Staking Rewards Rate: MOVRSRB

$$
MOVRSRB = avgAPR
$$

<table><thead><tr><th width="145">Formula Key</th><th width="169">Metric Name</th><th>Description</th></tr></thead><tbody><tr><td>avgAPR</td><td>Average Collator APR</td><td>The average annualized percentage rate across all active collators, derived from the network's round-based reward distribution mechanism. Each round, MOVR rewards are distributed to collators and their delegators based on stake weight and block production.</td></tr></tbody></table>

* MOVRSRB is non-compounded, excluding returns from reinvestment of rewards.
* Moonriver uses a Delegated Proof of Stake (DPoS) model with collators instead of validators.
* Moonriver is Kusama's canary network for Moonbeam, sharing the same DPoS architecture.

#### Slashing

* Moonriver does not implement slashing. Collators can be removed from the active set if they fail to meet minimum performance requirements, but staked tokens are not slashed.

### MOVR Collator Staking Rewards Rate: MOVRSRB(v)

Moonriver collators do not set individual commission rates. All collators share the same reward distribution mechanism defined by the protocol. Delegator rewards are determined by the delegator's share of the total stake on a given collator.

$$
MOVRSRB(v) = MOVRSRB
$$

* Since Moonriver collators do not have individual commission, the collator-level reward rate equals the network-level rate, adjusted by the delegator's proportion of the collator's total stake.

***

#### Observation Period:

1. The MOVRSRB is determined based on the current round reward parameters at the evaluation point.
2. This data is then annualized for a comprehensive year-long projection.

#### Calculation

The calculation happens every 6 hours and is immediately published via [Data API](https://www.stakingrewards.com/data-api).

#### Limitations

1. MOVRSRB employs a 365-day convention for annualizing reward data. This convention remains consistent and does not accommodate adjustments for leap years.

### MOVR Real Reward Rate: MOVRSRB^R

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

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

<table><thead><tr><th width="147">Formula key</th><th width="148">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>ir</td><td>Inflation Rate</td><td>Moonriver has a fixed 5% annual inflation rate, distributed among collators, the parachain bond reserve, and the treasury.</td></tr></tbody></table>

**Inflation Rate Behavior**

* Moonriver mirrors Moonbeam's inflation model with a fixed annual inflation rate of 5%. The distribution follows the same structure: collator staking rewards, parachain bond reserve, treasury allocation, and token burns. The effective staking inflation depends on the proportion allocated to collator rewards relative to total supply.
