I see how I see. I will break the information you requested.

What is the magic number used in block structure of the ethereum block structure?

In the lack, each block has a unique identifier called the “magic number”. This number is used to distinguish from one part of the same transaction from another. It plays a crucial role to ensure that different blocks contain data.

The magic number of Eramemum is 0xD9B4BEF9. However, why does it have this value and what does it mean?

What is the magic number used?

The magic number performs a few objectives:

Identifying **: It helps identify what the block contains a specification transaction or data.

differentiate : different blocks contain specific data and make it easy to verify and ensure their integrity.

Organization : Appointed the magic number when organizing blocks to the structure of the blocchan structure.

Why is the magic number always 0xd9b4bef9?

The value of the magic number may be arbitrary at first sight. However, it exists its significance is how to interact with other components of the lack block structure.

ENEREUM, Each transaction including a unique identifier (hash) and data. To ensure the integrity and organization of these transactions, the magic number is calculated as follows:

`Stronger

Blocksh + transachthsh + keeccak256 (data)

`Keck256C function is a CryptGraphica Hash function used in a variable-length input (data in this case). This calculation result is the magic number of one part.

What is it using?

Considering its composition and purpose, the magic number in Ether has severe practical applications:

Transaction Verification : The magic number ensures that blocks contain valid deals in the block.

Blockchan Organization

: It helps to maintain the integrity of the blocchane (magic numbers) based on their content.

Data Integrity : The calculation process used to create the magic number on each block is verified and prevents the taming with data.

Summary, the magic number on the 0xD9Bebef9, a critical component. Certifying the safety and integrity of the vehicle as an essential identifier for each partition.
