✉️Near SRB

Learn how NEAR staking rewards are calculated. NEARSRB formula covers epoch rewards from inflation, transaction fees, epoch time, and total staked NEAR.

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 and 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.

$$NEARSRB = er / et * t_d * t_y / st$$

Formula key	Metric name	Description
er	Epoch Rewards	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.
et	Epoch Time	The duration of one epoch in seconds.
st	Staked Tokens	The total amount of staked NEAR in the protocol's active validator set.
$t_d$	Day Constant	86400s
$t_y$	Year Constant	365d

• 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.

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

Formula key	Metric name	Description
c	Commission	The fee imposed by a specific validator to its delegators, expressed as numerator/denominator from the validator's reward fee fraction.

---

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.

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.

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

Formula key	Metric name	Description
ir	Inflation Rate	Derived from historical total supply changes over a 30-day window, annualized: (totalSupply_now - totalSupply_30dAgo) * (365/30) / totalSupply_30dAgo.

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.
