Ethereum: Bitcoin Main Generation Setup Without Downloading

When learning to learn about Bitcoin and Ethereum, it is necessary to understand how they synchronize their block circuits and check the operations without the need to download the blockchain completely. In this article, we will look at the basics of the bitcoin core setup and investigate how to prune the blockchain Instead of Using the Code.

What is pruning?

Pruning is an optimization technique used in distributed systems such as ethereum to reduce the amount of data to be transferred between the nodes (computers) or throatghout the network. By pruning, we Aim to Reduce the Amount of Unnecessary Data to Perform Operations More Efficiently and Faster.

Bitcoin Nucleus Setup: A Short Overview

To understand how bitcoin core sets a generation chain, let’s look at its architecture:

• Blockchain file : All blockchain is stored in a single file known as blockchain.dat.

• Block file : Each block contains an appropriate file containing metadata and surgery information.

• Chain link table (CRT) : This table is linked to each block to the previous block bag that allows you to look effective.

Pruning Without Downloading

We can use the following methods to prune the blockchain site:

• Block file arrow : We will replace the “blockchain. That” file to store a link table where the arrow of each block is linked to the appropriate file road.

• Chain Link Table (CRT) : Instead of Using CRT as described above, we will create a separate data structure for pruning purposes.

Code Implementation

Here’s an Example of Python:

`Python

Import hashlib

Def Get_block_Index (Block_hash):

“” Returns The Block Arrow, Accordination to his Bag “” “” “” “”

Let’s say the file “blockchain.dat” with this format:

Block-Eindex \ tbllock-Hash

Lines = [string to the line open (‘blockchain.dat’). Readlines () If not line.startswith (‘#’)]

blocks = {}

I, The Line Enumeration (in The Lines):

Arrow, block_hash = line.strip (). Split (‘\ t’)

Blocks [Int (Arrow)] = Block_hash

Return Blocks.get (Block_hash)

Def Prune_block (Block_Index):

“” CAUSED BY “Blockchain” by Removing Unnecessary Data “” “” “

Upload a blockchain file and create a link table

with open (‘blockchain.dat’, ‘r’) as f:

Lines = [Line.strip () Line F.Readlines ()]

Create an arrow map to hold bags or each block

Index_map = {}

I, The Line Enumeration (in The Lines):

If not line.startswith (‘#’):

blocks_str, index_str = line.split (‘\ t’)

Blocks_str = blocks_str [: -1]

remove the back of the “newline” Symbol

blocks_map [index_str] = blocks_str

Cut Blockchain by Removing Unnecessary Data

Block_index_str in Species (Blocks_str.keys ()):

Block_hash = Blocks [Block_Index_str]

If index_map.get (block_hash) == block_hash:

del index_map [block_hash]

Write the updated blockchain file

with open (‘blockchain.dat’, ‘W’) as f:

For rows in rows:

If not line.startswith (‘#’):

_, block_hash = Line.Split (‘\ t’)

Blocks_Map [Block_hash] = Blocks_str + ‘\ T’ + STR (Block_Index)

Otherwise:

F.Write (String)

Example of Use

Block_Index = get_block_index (‘your_block_hash_here)

Prune_block (block_index)
