Ethereum: How to get raw block data?

Acquisition of unprocessed blocks in Ethereum and Bitcoin core

In this article, we will examine two common methods to obtain unprocessed blocks: using the RPC « Getblockjson » method in Ethereum and the Json-RPC Bitcoin Core.

Ethereum: How to get data on unprocessed blocks

The “GetblockJson” RPC method is a popular way to load the block details, including the Blockchain header, a list of transactions and block data. To get data of unprocessed blocks using this method in Ethereum, you must:

• Identify the block number you want to access.

• Use Getblock with the ‘JsonRPC’ parameter set to"RAW".

Here is an example:

`Bash

ETH0-CLI Getblock 1234567890Jsonrpc = RAW & METHOD = GetblockStatebyhash & Params = [1234567890] & ID = 1

`

Replace 1234567890 with the block number you want to load, and run this command in your wallet compatible with Ethereum or the command line tool as » etshools « .

Bitcoin core: Get data on unprocessed blocks

On the contrary, the Bitcoin core provides the Json-RPC interface to obtain unprocessed data from blockchain. To get unprocessed data data using the JSON-RPC Bitcoin Core interface, you must:

• Install and configure the bitcoin core into your system.

• Use the Getblock command with theraw parameter set to " Jsonrpc = ".

Here is an example:

Bash

Bitcoin-Cli Getblock 1234567890raw = Jsonrpc = 1

`

Replace 1234567890 with the block number you want to load and run this command in your Bitcoin nuclear wallet or in the command line tool likeBitcoin-QT.

Important notes:

• The Getblockjson method is commonly used to load details of the analyzed block, while unprocessed data require the “RAW” parameter.

• Command Getblock with parameter ‘Rawsets the output format to JSON-RPC, which may not be suitable for displaying large blocks.

Conclusion:

Although both methods allow you to load data on Ethereum and Bitcoin Core blocks, using the "Getblockjson" method is generally more convenient for details of the analysis of the block. However, if you need unprocessed blocks, the "Getblock with parameter » RAW « may be a viable alternative, especially when working with large blocks or in an environment where the JSon-RPC output is not feasible.

Be sure to always follow the proven procedures for processing and storing sensitive data such as wallets and private keys.
