What does a blockchain browser have? How to use a block browser? In life, if we want to query some news, we will habitually search on Baidu. Baidu is a search engine, which is also a browser. Searching with a browser can quickly find the information we need. For blockchain, there are also blockchain browsers. In fact, we can also query a lot of information about the blockchain using an ordinary browser. However, if we want to query some particularly professional information, such as fast hashing, confirmation numbers, etc., we need to use a blockchain browser. Blockchain browsers can provide more professional and accurate information.

**1. What is a blockchain browser?**

Blockchain browser is simply a search tool. By entering a certain wallet address or a certain transaction ID, we can query the balance of this wallet and the details of any transaction: For example, the current transfer fee of Bitcoin is How much, how rich is the address to which you are transferring money, when will a transfer arrive... Of course, we can also search for all the contents of a specific block by entering the block height, block hash, etc.

Tokenview is used as an introduction here because this blockchain browser can query the information of more than six mainstream electronic currencies at one time, and can also query the latest blockbuster, which is more versatile.

**2. What can a blockchain browser do?**

Let’s take a look at the functionality of the blockchain explorer in practice.

First enter the blockchain browser URL www.tokenview.com to jump to the Tokenview homepage:

At this time, we can enter the content we want to search in the search bar, such as [Transaction ID], [Wallet Address], [Block Height], [Block Hash] and other information (Ps: For the specific meaning, see the third article below. Partial explanation).

Taking the BTC address 35xbMDKSo**********************1Zhyk as an example to view the transaction information, the address's balance, total income, total transfers, transaction quantity and its transactions will be displayed. history record.

Click [In Progress] directly on the homepage and you will see the "latest explosive blocks" of popular currencies.

"Latest block" refers to the latest generated block. In this interface, there are block height, date, block size and income of different currencies. You can get more information about the corresponding currency by clicking [Learn More] under different currencies.

**3. Understand blockchain terminology in seconds**

I believe that for many novices who are using blockchain browsers for the first time, they must have a headache with related terminology. Next, I will explain to you the relevant terms of the blockchain in the form of a combination of pictures and texts (taking BTC as an example).

1. Block Hash

The block hash is a number obtained by hashing the block header twice. It is one of the identifiers of the block and can uniquely and clearly identify a block.

2. Block height

The block height refers to the number of Bitcoin blocks mined since the creation block. It is one of the identifiers of the block, but it does not identify a single block. Two or more blocks may have the same block height and occupy the same position in the blockchain.

The height of the block above is 519659, that is, 519659 blocks have been generated since the genesis block.

3.Date

The latest date of the block transaction (local time of the user). Placing the cursor on a date will display the corresponding UTC.

4. Block size

The size of each block is not fixed and is related to the number of transactions, but the maximum value of each block is 2M. The size of the 519659th block in the figure below is 33988Bytes.

5. Transaction fees

That is, the transfer fee is related to the number of bytes occupied by the transaction and has nothing to do with the transfer amount. The transaction fee for block 519659 in the picture below is 0.005678880000001241BTC.

6. Number of confirmations

How many blocks have confirmed your transaction record?

7. Total transfer amount

The total amount of transfers is the total number of transfers in the current block. In this example, the total transfer amount of block 519659 is 125.69065651 BTC.

8. Mining difficulty

Measuring the average number of operations required to mine a block, it reflects how long it takes to mine a certain number of blocks at a certain difficulty.

9. Transaction quantity

The total number of transactions contained in the current block. For example, in the 519659th block in this example, there were 76 transactions as of 09:37:51 on April 24, 2018.

After reading this, I believe you already have an overall understanding of blockchain browsers. How about it? Just type in a wallet address and enter it to give it a try.
