# Near SRB

NEARSRB is a benchmark representing the mean, annualized staking rate across all active Near-Protocol validators.

NEARSRB is calculated and published by Staking Rewards via the [Near Profile](https://www.stakingrewards.com/asset/near-protocol) and [Data API](https://www.stakingrewards.com/data-api).

> **TL;DR:** NEAR staking rewards come from protocol inflation (90% of inflation goes to validators) minus transaction fees, distributed per epoch. The reward rate equals epoch rewards annualized divided by total staked NEAR. Inflation is derived from 30-day supply changes.

$$
NEARSRB = er / et \* t\_d \* t\_y / st
$$

<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>er</td><td>Epoch Rewards</td><td>The total rewards distributed per epoch to validators. Derived from annual inflation (90% of total inflation goes to validators) minus annualized transaction fees, divided by the number of epochs per year.</td></tr><tr><td>et</td><td>Epoch Time</td><td>The duration of one epoch in seconds.</td></tr><tr><td>st</td><td>Staked Tokens</td><td>The total amount of staked NEAR in the protocol's active validator set.</td></tr><tr><td><span class="math">t_d</span></td><td>Day Constant</td><td>86400s</td></tr><tr><td><span class="math">t_y</span></td><td>Year Constant</td><td>365d</td></tr></tbody></table>

* NEARSRB is non-compounded, excluding returns from reinvestment of rewards.
* Inflation rate is derived from historical total supply changes over a 30-day window, not a fixed constant.

#### Slashing

1. Currently, slashing is not implemented in the Near Protocol.

### NEAR Validator Staking Reward Rate: NEARSRB(v)

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

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

<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, expressed as numerator/denominator from the validator's reward fee fraction.</td></tr></tbody></table>

***

#### Observation Period:

1. The NEARSRB is determined based on the latest epoch and protocol configuration at the evaluation point.
2. This data is then annualized for a comprehensive year-long projection.

#### Calculation

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

#### Limitations

1. NEARSRB employs a 365-day convention for annualizing current epoch times. This convention remains consistent and does not accommodate adjustments for leap years.

### NEAR Real Reward Rate: NEARSRB^R

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

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

<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>ir</td><td>Inflation Rate</td><td>Derived from historical total supply changes over a 30-day window, annualized: (totalSupply_now - totalSupply_30dAgo) * (365/30) / totalSupply_30dAgo.</td></tr></tbody></table>

**Inflation Rate Behavior**

* NEAR Protocol targets approximately 5% annual inflation, of which 90% (4.5% of total supply) is allocated to validators as epoch rewards and 10% goes to the protocol treasury. Transaction fees are burned, partially offsetting inflation. The effective inflation rate is measured from actual total supply changes over time rather than a fixed constant.
