Here is my code :
```javascript
const { ethers } = require("ethers");
const network = "mainnet";
const demo = api_key;
const provider = new ethers.providers.AlchemyProvider(
network,
demo
);
const querryBlockchain = async () => {
const blockNumber = await provider.getBlockNumber();
console.log(blockNumber);
};
querryBlockchain();
```
