# eth\_getBlock

```
web3.eth.getBlock(blockHashOrBlockNumber [, returnTransactionObjects] [, callback])
```

#### Parameters

1. The block number or block hash. Or the string `"earliest"`, `"latest"` or `"pending"` as in the [default block parameter](https://web3js.readthedocs.io/en/v1.3.0/web3-eth.html#eth-defaultblock).
2. (optional, default `false`) If specified `true`, the returned block will contain all transactions as objects. If `false` it will only contains the transaction hashes.
3. (optional) Optional callback, returns an error object as first parameter and the result as second.

#### Returns

The block object:

> * `number`: The block number. `null` if a pending block.
> * `hash`: Hash of the block. `null` if a pending block.
> * `parentHash`: Hash of the parent block
> * `sha3Uncles` : SHA3 of the uncles data in the block.
> * `logsBloom`: The bloom filter for the logs of the block. `null` if a pending block.
> * `transactionsRoot`: The root of the transaction trie of the block.
> * `stateRoot` : The root of the final state trie of the block.
> * `miner` : The address of the beneficiary to whom the mining rewards were given.
> * `difficulty` : Integer of the difficulty for this block.
> * `totalDifficulty`: Integer of the total difficulty of the chain until this block.
> * `extraData`: The “extra data” field of this block.
> * `size`: Integer the size of this block in bytes.
> * `gasLimit`: The maximum gas allowed in this block.
> * `gasUsed`: The total used gas by all transactions in this block.
> * `timestamp`: The unix timestamp for when the block was collated.
> * `transactions`: Array of transaction objects, or 32 Bytes transaction hashes depending on the `returnTransactionObjects` parameter.
> * `uncles`: Array of uncle hashes.
> *   author ：
