# Provenance Blockchain SRB

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.

### HASH Staking Rewards Rate: HASHSRB

Since annual provisions are 0, the ATOMSRB formula simplifies to:

$$
HASHSRB = (df\_{30d} \* t\_y) \* (1 - ct) / st\_{active}
$$

<table><thead><tr><th width="145">Formula Key</th><th width="205">Metric Name</th><th>Description</th></tr></thead><tbody><tr><td>df<sub>30d</sub></td><td>Average Daily Fees (30d)</td><td>The 30-day rolling average of daily transaction fees denominated in HASH. Fees are estimated by sampling transactions across recent blocks and multiplying by an average gas cost of 4.89 nhash per transaction.</td></tr><tr><td>ct</td><td>Community Tax</td><td>The percentage of fee rewards sent to the community pool at each block.</td></tr><tr><td>st<sub>active</sub></td><td>Active Staked Tokens</td><td>The total number of HASH tokens bonded with active (non-jailed) validators.</td></tr><tr><td><span class="math">t_y</span></td><td>Year Constant</td><td>365d</td></tr></tbody></table>

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 Estimation Methodology**

Daily fees are estimated by sampling the most recent 2 hours of blocks (\~120 minutes / block\_time). For each block, the number of transactions is counted and multiplied by an average gas cost of 4.89 nhash per transaction. This 2-hour sample is then extrapolated to a 24-hour period. The reward rate uses a 30-day rolling average of these daily fee estimates to smooth out short-term volatility.

**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.
* The gas cost estimate of 4.89 nhash per transaction is an average; actual transaction fees vary by transaction type and complexity.
* 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.

$$
HASHSRB(v) = HASHSRB \* p \* (1 - cr)
$$

<table><thead><tr><th width="147">Formula Key</th><th width="165">Metric Name</th><th>Description</th></tr></thead><tbody><tr><td>p</td><td>Performance</td><td>The 7-day average percentage of successfully signed blocks, calculated as 1 minus (missed blocks / historical entries). Clamped to the 0-1 range.</td></tr><tr><td>cr</td><td>Commission Rate</td><td>The percentage commission rate the validator has set as a delegation fee. Minimum 60% enforced by the chain.</td></tr></tbody></table>

***

### HASH Real Reward Rate: HASHSRB^R

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

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

<table><thead><tr><th width="147">Formula Key</th><th width="148">Metric Name</th><th>Description</th></tr></thead><tbody><tr><td>ir</td><td>Inflation Rate</td><td>The annual provisions divided by the circulating supply. For Provenance Blockchain, this is 0.</td></tr></tbody></table>

**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

<table><thead><tr><th width="190">Metric</th><th>Description</th></tr></thead><tbody><tr><td>Staked Tokens</td><td>The total number of HASH tokens bonded with all validators.</td></tr><tr><td>Delegated Tokens</td><td>The number of HASH tokens delegated to validators by external delegators.</td></tr><tr><td>Self Staked Tokens</td><td>The number of HASH tokens bonded by validators directly.</td></tr><tr><td>Staking Wallets</td><td>This metric refers to the total quantity of distinct delegations made. It doesn't distinguish based on unique delegator addresses and excludes considerations of any minimum delegation thresholds.</td></tr><tr><td>Fee Revenue</td><td>The annualized transaction fees evaluated at the prevailing USD rate, derived from the daily fee estimate.</td></tr><tr><td>Daily Fees</td><td>Estimated daily transaction fees in HASH, calculated by sampling recent blocks and extrapolating.</td></tr></tbody></table>
