# Network Overview

Build network dashboard widgets that display key Kadena blockchain metrics.

## NetworkInfo: KDA Supply

Retrieve essential network statistics for dashboard widgets and analytics platforms.


```graphql
query NetworkInfo {
  networkInfo {
    coinsInCirculation
  }
}
```

**Variables**


```json
{}
```

**Response**


```json
{
  "data": {
    "networkInfo": {
      "coinsInCirculation": 331907696.42982113
    }
  }
}
```

**Use Cases**

- Homepage KPI widgets
- Market cap calculations
- Network statistics dashboards
- Ecosystem overview displays


**Notes**
Total KDA supply updates in real-time as new blocks are mined. Essential for calculating market cap when combined with price data.

## NetworkInfo: Network Hash Rate

Retrieve current network hash rate for mining difficulty and security analysis.


```graphql
query NetworkHashRate {
  networkInfo {
    networkHashRate
  }
}
```

**Variables**


```json
{}
```

**Response**


```json
{
  "data": {
    "networkInfo": {
      "networkHashRate": 501808397925133630
    }
  }
}
```

**Use Cases**

- Mining difficulty dashboards
- Network security monitoring
- Hash rate trend analysis
- Mining pool statistics


**Notes**
Hash rate represents the total computational power securing the network. Higher values indicate stronger network security.

## NetworkInfo: Total Difficulty

Retrieve cumulative mining difficulty for blockchain security analysis.


```graphql
query TotalDifficulty {
  networkInfo {
    totalDifficulty
  }
}
```

**Variables**


```json
{}
```

**Response**


```json
{
  "data": {
    "networkInfo": {
      "totalDifficulty": 13004030628148382000
    }
  }
}
```

**Use Cases**

- Blockchain security metrics
- Mining progression analysis
- Network maturity indicators
- Historical difficulty tracking


**Notes**
Total difficulty represents cumulative work done since genesis. Continuously increases as blocks are mined and difficulty adjusts.

## LastBlockHeight: Current Block Progress

Retrieve the highest block height across all chains to show current blockchain progress.


```graphql
query Query {
  lastBlockHeight
}
```

**Variables**


```json
{}
```

**Response**


```json
{
  "data": {
    "lastBlockHeight": 6211678
  }
}
```

**Use Cases**

- Network status dashboards
- Blockchain sync indicators
- Progress tracking displays
- Health monitoring systems


**Notes**
Represents the highest block height across all 20 chains. Updates in real-time as new blocks are mined.
