HASHSRB is a fee-only Cosmos SDK chain with 0% inflation where rewards come exclusively from transaction fees. HASHSRB is a benchmark representing the mean, annualized staking rate across all active Provenance Blockchain validators. HASHSRB is calculated and published by Staking Rewards via the [Provenance Blockchain Profile](https://www.stakingrewards.com/asset/provenance-blockchain) and [Data API](https://www.stakingrewards.com/data-api). > **TL;DR:** Provenance Blockchain is a fee-only Cosmos SDK chain with 0% inflation. Staking rewards come exclusively from transaction fees. The formula uses annualized 30-day average daily fees, minus community tax, divided by active staked tokens. The chain enforces a 60% minimum validator commission. {% hint style="warning" %} Unlike most Cosmos SDK chains, Provenance Blockchain has **zero annual provisions** (0% inflation). All staking rewards are derived exclusively from transaction fees. The standard ATOMSRB formula still applies, but the `ap` (annual provisions) term is always 0, making fees the sole source of staker income. {% endhint %} {% hint style="info" %} The calculations are derived from the ATOMSRB documentation, serving as the foundational reference to ensure the accuracy of relevant metrics. For more information visit the [ATOMSRB docs](https://docs.stakingrewards.com/staking-data/methodologies/cosmos-hub-srb). {% endhint %} {% content-ref url="/pages/aKwZW2LPk4OF6A8oB6OI" %} [Cosmos Hub SRB](/staking-data/methodologies/cosmos-ecosystem-srb/cosmos-hub-srb.md) {% endcontent-ref %} ### HASH Staking Rewards Rate: HASHSRB Since annual provisions are 0, the ATOMSRB formula simplifies to: $$ HASHSRB = (df\_{30d} \* t\_y) \* (1 - ct) / st\_{active} $$
Formula KeyMetric NameDescription
df30dAverage Daily Fees (30d)The 30-day rolling average of daily transaction fees denominated in HASH. Daily fees are measured from the growth of the community pool over a trailing 7-day window, inverted by the community tax.
ctCommunity TaxThe percentage of fee rewards sent to the community pool at each block.
stactiveActive Staked TokensThe total number of HASH tokens bonded with active (non-jailed) validators.

This is equivalent to the full ATOMSRB formula with `ap = 0`: $$ HASHSRB = (ap + df\_{30d} \* t\_y) \* (1 - ct) / st\_{active} \quad \text{where } ap = 0 $$ * HASHSRB takes into account all accumulated rewards, whether they have been claimed or remain unclaimed. * HASHSRB operates on a non-compounded basis, meaning it excludes returns generated from the reinvestment of rewards. * HASHSRB is based on an assumption of 100% validator efficiency. For a SRB Reward Rate adjusted according to individual validator performance, please refer to HASHSRB(v). **Fee Measurement Methodology** Daily fees are measured directly from the community pool rather than estimated from a per-transaction constant. Every transaction fee paid on Provenance Blockchain enters the distribution module, which taxes a fixed share (the community tax, currently 7%) into the community pool and pays the remainder to validators and their delegators. Total fees over any interval can therefore be recovered exactly by measuring how much the community pool grew and dividing by the community tax: $$ df = \frac{\Delta{pool}}{ct} \div t\_{elapsed} $$ The community pool balance is read at the current block height and again at a block approximately 7 days earlier, using archival state queries. The elapsed span is measured from the two block timestamps rather than assumed from a fixed block rate, so the result does not drift as block time changes. The reward rate then uses a 30-day rolling average of these daily fee values to smooth out short-term volatility. A 7-day measurement window is used rather than a single day because daily fee activity on Provenance Blockchain is volatile (a coefficient of variation of roughly 47% day-to-day, against roughly 4% over 7-day windows), and the Daily Fees and Fee Revenue metrics are published from the instantaneous measurement rather than the 30-day average. This replaces an earlier method that counted transactions across a 2-hour block sample and multiplied by a fixed average fee of 4.89 HASH per transaction. That constant was calibrated in April 2026 and did not track the chain's subsequent fee schedule; because Provenance Blockchain's fee distribution is strongly bimodal, a single per-transaction average is not a reliable estimator. Measuring the pool directly removes the constant entirely. **60% Minimum Commission** Provenance Blockchain enforces a chain-level minimum validator commission of 60%. This means delegators retain at most 40% of the gross staking rate. This minimum is enforced at the protocol level and cannot be lowered by individual validators. #### Slashing * HASHSRB does not factor in the possibility of slashing occurrences. * It's important to note that if validator entities face slashing, rewards will increase, as the slashed tokens are reallocated among validators. #### Observation Period * The HASHSRB is determined based on the latest generated block at the point of evaluation. * Daily fee data is averaged over a 30-day rolling window and 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 * HASHSRB employs a 365-day convention for annualizing fees. This convention remains consistent and does not accommodate adjustments for leap years. * Since rewards come exclusively from transaction fees, the staking rate is directly dependent on network usage. Periods of low transaction volume will result in lower staking rewards. * Daily fees are measured over a trailing 7-day window, so the Daily Fees and Fee Revenue metrics respond to a genuine change in network activity over several days rather than immediately. * The measurement assumes the community pool grows only from transaction fees. A governance-approved community pool spend would reduce the pool and understate measured fees for that window. No such proposal has been made on this chain to date, and a measurement that fails its validity checks is omitted rather than published as zero. * Individual validator rates may differ from HASHSRB due to commission rates, performance, and the 60% minimum commission enforcement. *** ### HASH Validator Staking Rewards Rate: HASHSRB(v) Staking Rewards calculates the HASHSRB for each validator based on their individual 7-day average performance and commission rate. $$ HASHSRB(v) = HASHSRB \* p \* (1 - cr) $$
Formula KeyMetric NameDescription
pPerformanceThe 7-day average percentage of successfully signed blocks, calculated as 1 minus (missed blocks / historical entries). Clamped to the 0-1 range.
crCommission RateThe percentage commission rate the validator has set as a delegation fee. Minimum 60% enforced by the chain.
*** ### HASH Real Reward Rate: HASHSRB^R The real reward rate calculates the HASHSRB adjusted for inflation in the network. $$ HASHSRB^R = (1 + HASHSRB) / (1 + ir) - 1 $$
Formula KeyMetric NameDescription
irInflation RateThe annual provisions divided by the total on-chain supply of the bond denom. For Provenance Blockchain, this is 0.
**Inflation Rate Behavior** * Provenance Blockchain operates with a **0% inflation model**. There are no annual provisions or token emissions. All staking rewards are sourced entirely from transaction fees paid by network users. * Since `ir = 0`, the real reward rate equals the nominal reward rate: `HASHSRB^R = HASHSRB`. * This fee-only model means the token supply is not diluted by staking rewards, and stakers capture real economic value from network usage rather than inflationary subsidies. *** ### Other Provenance Blockchain metrics calculated by Staking Rewards
MetricDescription
Staked TokensThe total number of HASH tokens bonded with all validators.
Delegated TokensThe number of HASH tokens delegated to validators by external delegators.
Self Staked TokensThe number of HASH tokens bonded by validators directly.
Staking WalletsThis metric refers to the number of unique delegator addresses with at least one delegation on-chain. An address delegating to several validators is counted once. It excludes considerations of any minimum delegation thresholds.
Fee RevenueThe annualized transaction fees evaluated at the prevailing USD rate, derived from the daily fee measurement.
Daily FeesDaily transaction fees in HASH, measured from the growth of the community pool over a trailing 7-day window.
