Ethereum: What is the difference between chainstate and blocks folder?

** Ethereum: Chainsstate vs Blocks fold

Ethereum ecosystem, both Chainstate and Blocksfolder, are essential components to store and obtain Blockchain data. However, they serve for different purposes, so it is important to understand their disagreement before reading and showing the web front.

Chainsstate

The Chainstate folder is the most important storage mode of the Ethereum mode containing a variety of information, such as:

• The height of the block

• Block number

• Block the time tag

• Number of events

• The price of gas

• The amount of surgery is not approved

The Chainstate folder stores this information in a hierarchical structure, each file depicts a block or block chain. The files are divided into lists such as State_root, State_tree and TX_Count.

prevented the folder

Blocksfolder is responsible for storing individual blocks. Each block contains a variety of data such as:

• Block Hash

• Previous block bag (parents’ bag)

• Number of events

• The amount of surgery is not approved

• The price of gas

• Time tag

Blocksfolder stores each block in a separate file, each file describes one block.

General Differences

Although both folders hold the same type of information, there are basic differences:

• Chainstate is the most important storage of Ethereum mode, while Blocksfolder protects separate blocks.

• Chainstate files have a hierarchical structure that includes all directories containing sub -sections and files, while Blocksfolder has separate files for each block.

Reading and Displaying Information

You need to use Chainsstate and Blocksfolder to read and show the network in front, such as Blockchain Explorer. Here is an example of how this is done with a solid (Ethereum programming language) and web3.js:

`Javascript

Bring * web3 from web3;

Const web3 = new web3 (new web3.providers.httpprovider (‘

// Get Chainsstate

Const chinstate = web3.eth.chaystate;

// Get all blocks

Async’s feature of Getbocks () {

Const txlist = Wait web3.et.gettraSactionlist ();

for (let i = 0; i

Const block = txlist [i] .block;

// Read the Chainsstate Block Information

Console.log (block.itimestamp);

}

}

// Get a particular block under her bag

Async’s feature of getblockbyhash () {

Const blockhash = ‘0x1234567890ABCDEF’;

Const blockdata = wait for web3.eth.getblock (blockhash, true);

// Read Blockfolder Block Information

Console.log (blockdata.hash);

}

`

Information that appears in front of the network

You need to use a web3.js ethical library to show web information, such as Blockchain Explorer, to interact with the Ethereum network and scan certain information. You can then use HTML5 fabric or other technology to visualize data.

Here is an example of how you can show the block time tag on HTML5 fabric:
