Learn how Ontology staking rewards are calculated. ONTSRB formula covers ONG emissions, dual-token model, transaction fees, and staked ONT value.

ONTSRB is a benchmark representing the mean, annualized staking rate across all active Ontology validators.

ONTSRB is calculated and published by Staking Rewards via the Ontology Profile and Data API.

TL;DR: Ontology uses a dual-token model where staking rewards are paid in ONG (utility token) to ONT stakers. The reward rate combines yearly ONG emissions plus annualized fee revenue in USD, divided by total staked ONT value.

ONT Staking Rewards Rate: ONTSRB

Ontology uses a dual-token model: ONT is the staking and governance token, while ONG is the utility and reward token. Staking rewards are distributed in ONG, so the reward rate is expressed as the USD-denominated return on staked ONT.

$$ONTSRB = (e_{ong} * p_{ong} + fr) / (st * p_{ont})$$

Formula key	Metric name	Description
$e_{ong}$	Yearly ONG Emissions	The total ONG emitted per year. Currently 31,536,000 ONG (1 ONG per second).
$p_{ong}$	ONG Price	The current market price of ONG in USD.
fr	Fee Revenue	Annualized transaction fee revenue in USD (daily ONG fees × 365 × ONG price).
st	Staked Tokens	The total number of ONT tokens currently staked across all validators.
$p_{ont}$	ONT Price	The current market price of ONT in USD.

• ONTSRB takes into account all accumulated rewards, whether they have been claimed or remain unclaimed.

• ONTSRB operates on a non-compounded basis, meaning it excludes returns generated from the reinvestment of rewards.

• ONTSRB accounts for both ONG emissions and transaction fee revenue distributed to stakers.

ONG Emission Schedule

ONG emissions follow a decreasing schedule from mainnet launch (June 30, 2018):

Year	ONG per Second	Yearly ONG
1–2	5	157,680,000
3	4	126,144,000
4–5	3	94,608,000
6–8	2	63,072,000
9+	1	31,536,000

As of 2026, the network is in the 1 ONG/sec period. Following the v3.0.0 upgrade (December 2025), 80% of ONG emissions are allocated to stakers and 20% to the ecosystem fund.

Slashing

Ontology does not implement slashing. Validators that fail to meet performance requirements are demoted from Consensus Node to Candidate Node status rather than having their stake slashed.

ONT Validator Staking Rewards Rate: ONTSRB(v)

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

$$ONTSRB(v) = ONTSRB * (1 - cr)$$

Formula key	Metric name	Description
cr	Commission Rate	The percentage of rewards retained by the validator. Derived from the user proportion: cr = 1 − user_proportion.

Validator Types

Ontology distinguishes between two validator types:

Type	Description
Consensus Node	Active block-producing validators participating in consensus.
Candidate Node	Validators that have applied but are not currently participating in consensus.

Observation Period:

1. ONTSRB is determined based on the latest data at the point of evaluation.

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

• ONTSRB employs a 365-day convention for annualizing ONG emissions and daily fees. This convention remains consistent and does not accommodate adjustments for leap years.

• ONTSRB does not account for potential changes to the ONG emission schedule within a calculation period.

• Individual validator reward rates may vary based on the validator's commission rate and node type.

ONT Real Reward Rate: ONTSRB^R

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

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

Formula key	Metric name	Description
ir	Inflation Rate	The rate at which new ONT enters the circulating supply.

Inflation Rate Behaviour

ONT has a fixed total supply of 1,000,000,000 tokens with no minting mechanism. The inflation rate is 0%. As a result, the real reward rate equals the nominal reward rate.

Other Ontology metrics calculated by Staking Rewards:

Metric	Description
Delegated Tokens	Number of ONT tokens delegated to validators by stakers.
Self Staked Tokens	Number of ONT tokens staked by validators directly (initial stake).
Staking Wallets	Total unique delegations across all validators.
Fee Revenue	Annualized transaction fees in USD.
Yearly ONG Emissions	Total ONG emitted per year under the current emission schedule.
