# eth\_getBlockByNumber - Somnia

Example code for the eth\_getBlockByNumber JSON-RPC method. Complete guide on how to use eth\_getBlockByNumber JSON-RPC in GetBlock Web3 documentation.

This method returns information about a block by block number on the Somnia network. With Somnia's \~100ms block times, blocks are produced rapidly, containing transactions processed through the MultiStream consensus mechanism.

## Parameters

| Parameter        | Type    | Required | Description                                                                     |
| ---------------- | ------- | -------- | ------------------------------------------------------------------------------- |
| blockNumber      | string  | Yes      | Block number in hex, or "latest", "earliest", "pending"                         |
| fullTransactions | boolean | Yes      | If true, returns full transaction objects; if false, returns transaction hashes |
