💎The Open Network SRB

The Open Network Staking Rewards Benchmark (TONSRB™) Methodology

TONSRB is a benchmark representing the annualized staking rate for TON token.

TONSRB is calculated and published by Staking Rewards via the TON Profile and Data API.

$$TONSRB = dr * t_y / es$$

Formula key	Metric name	Description
dr	Daily Rewards	Total rewards from the last 30 days of staking cycles, divided by the number of days elapsed.
es	Effective Stake	The average staked tokens across cycles in the 30-day observation window.
$t_y$	Year Constant	365d

• TONSRB uses a 30-day rolling window of staking cycles for reward calculation.

• TONSRB is non-compounded, excluding returns from reinvestment of rewards.

TON Validator Staking Rewards Rate: TONSRB(v)

Staking Rewards calculates the TONSRB for each validator based on their individual commission rate. TON distinguishes three validator contract types:

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

Formula key	Metric Name	Description
cr	Commission Rate	The commission rate the validator has set as a delegation fee. Applies to nomination pool validators. Single validators and whale pools have no commission.

Validator Types:

Type	Description
Nomination Pool	Accepts delegations. Commission applies. Self-staked and delegated tokens tracked separately.
Single Validator	Solo operator. All stake is self-staked. Marked as private. No commission.
Whale Pool	Large-stake pool. All stake is treated as delegated. No commission.

TON Real Reward Rate (TONSRB^R)

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

$$TONSRB^R = 1+TONSRB/(1+i)-1$$

Formula Key	Metric name	Description
i	Inflation Rate	Derived from the annualized rewards relative to circulating supply.

---

Observation Period:

1. The TONSRB is determined based on the last 30 days of staking cycles 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. TONSRB employs a 365-day convention for annualizing staking rates. This convention remains consistent and does not accommodate adjustments for leap years.

Data Sources:

• TON network APIs for cycle-by-cycle reward data, block stats, and validator pool details

• TON election data for current validator set

• TON network fee data

• CoinGecko for price and supply data
