Ethereum: How to get raw block data?

Posted on by chang mr.

Getting Raw Block Data from Ethereum and Bitcoin Core

In this article, we will explore two common methods for retrieving raw block data: Ethereum’s getblockjson RPC method and using the JSON-RPC interface in the Bitcoin Core wallet.

Ethereum: How to Get Raw Block Data

The getblockjson RPC method is a popular way to retrieve block details, including the blockchain header, transaction list, and block data. To get raw block data using this method on Ethereum, you will need to:

  • Identify the block number you want to access.
  • Use the getblock command with the jsonrpc parameter set to "raw".

Here is an example:

`hit

eth0-cli getblock 1234567890jsonrpc=RAW&method=getblockstatebyhash¶meters=[1234567890]&id=1

Replace1234567890with the block number you want to retrieve and run this command in your Ethereum-compatible wallet or a command-line tool likeetools.

Bitcoin Core: How to Get Raw Block Data



In contrast, Bitcoin Core provides a JSON-RPC interface to retrieve raw data from the blockchain. To retrieve raw block data using Bitcoin Core's JSON-RPC interface, you will need to:
  • Install and configure Bitcoin Core on your system.
  • Use thegetblockcommand set to"jsonrpc=".
Here is an example:
`blow
bitcoin-cli get block 1234567890raw=jsonrpc=1

Replace 1234567890with the block number you want to retrieve and run this command in your Bitcoin Core wallet or a command line tool likebitcoin-qt.

Important Notes:

  • Thegetblockjsonmethod is commonly used to get parsed block details, and therawparameter is required for raw data.

Thegetblockcommand with the **raw parameter sets the output format to JSON-RPC, which may not be suitable for displaying large blocks.

Conclusion:

Ethereum: How to get raw block data?

While both methods allow you to get raw block data on Ethereum and Bitcoin Core, using the getblockjson method is often more convenient for parsing block details. However, if you need raw block data, the getblock command with the raw parameter can be a viable option, especially when working with large blocks or in environments where JSON-RPC output is not possible.

Remember to always follow best practices for handling and storing sensitive data such as wallet passwords and private keys.
