Ethereum: is it possible to decode block height from a blockhash?

Here’s an article on whether it is possible to decode the height of the blocks from locking:

Locking height decoding from locking: Bitcoin network customer consideration

As a Bitcoin network customer developer, you are probably known for the Blockhash format used by the Bitcoin network. When a new block is connected to the circuit, Blockhash is created, which contains information about the block header and data. One of the useful features of this format is that it allows us to decode certain values ​​from blocking.

In this article, we will find out whether it is possible to decipher the height of the blocks from locking, especially by receiving a new block inventory vector.

What is blockhash?

Blockhash has a 64 -bytes string containing a block on the Bitcoin network. This includes block hash, version and other metadata. The Blockhash format is designed for compact and efficient, allowing a quick and reliable data transmission between the nodes on the Bitcoin network.

Can we decipher the block height from locking?

Yes, it is possible to decode the height of the blocks from the lock. However, this value depends on the knot used in the particular version of the knot that created it.

Bitcoin 0.8 and latest versions in the blocking format include an additional field called “Block_Height” (also known as “height”). This field contains the block height in the bytes.

Locking height decoding from locking

You can use the following steps to decipher the block height from locking:

• Put the locking string in your application.

• Check the value of Block_Height and get 64 bytes content as an unsigned integer array.

• Use this array to create a block height in the bytes.

Here are some C ++ sample code showing how to decode a blockhash and retrieve the block height:

`Cpp

#Include

#InCLUDE

STD :: UINT8_T Decode_Block_Height (Const uint8_t blockhash) {

// Check if Block_hash is valid (is length <= 64)

IF (Blockhash == NullPTR || Blockhash-> Length! = 64) {

Return nullptr;

}

// Remove the block height from the blockhash

STD :: uint32_t block_height = ((STD :: uint32_t*) blockhash) [0];

// convert block height to bytes and return it as a C-breed array unsigned whole numbers

uint8_t block_height_bytes = new uint8_t [block_height 4];

Memcpy (block_height_bytes, & block_height, SIZEOF (STD :: uint32_t));

STD :: Memcpy (& Block_Height_bytes [0], (Const Char*) Blockhash + 1, SIZEOF (STD :: uint32_t));

Return block_height_bytes;

}

When to decode the height of the blocks?

You should consider deciphering the block height from locking the following scenarios:

• Receiving new blocks with their dignity vectors.

• Updating the condition or configuration of the node based on the data received.

Keep in mind that blocking height decoding is an optimization of low latency operations as it allows you to retrieve and immediately use the block height without waiting for the full block header to load from the disk or network.

Conclusion

Locking height decoding from locking is a useful feature that can be used in various scenarios in your Bitcoin network customer. By taking the dissertation steps and using the Decode_Block_Height feature, you will be able to retrieve the height of the incoming block block and use your resources more efficiently.
