## SnapShot Mainnet - updated every 5 hours

<summary>RPC Scanning</summary>

### We scan nodes in real time every 4 hours. And we provide the final result of RPC endpoints. We cannot influence the operation of these nodes in any way.

```python
If Voting Power is higher than 0 --> then the Node is a validator of the network and may be subject to attack and be a potential threat to the chain.
```

```python
We marked such validators with a red symbol
```
