First, blockchain browser?

When I first hear this term, I think everyone will have a series of questions in their mind, a series of question marks. What is a Blockchain browser? Is Blockchain Browser a token explorer? Is it a program built on a blockchain public chain?

The blockchain browser is a website through which you can query some information about the blockchain, such as searching for transaction records, details of a certain block, the height of the current chain, etc. You can also check the balance or transaction details by wallet address or transaction ID. So the blockchain browser is not an application, nor is it a program built on the blockchain public chain. In simple terms, it is a website that can query blockchain data. And it's built on a common centralized network. Maybe you still can't fully understand, it doesn't matter, I'll give you another example, we take the ordinary browser and blockchain browser to compare.

Ordinary browsers and blockchain browsers are used to query information, the difference is that ordinary browsers query some science or life information information, etc., we can use ordinary browsers to log in to various types of websites, query all kinds of information and news, and even use browsers to listen to songs, play web games and so on. However, the blockchain browser can only query information or transaction information related to the blockchain, which is a highly professional information website. In fact, the blockchain browser is the "blockchain information query website", it is not an application, but an ordinary browser can access a website, this website can query all the relevant information of the blockchain.

Second, after introducing the concept of blockchain browser, let's popularize the terms often used in blockchain browser queries.

Block hash

A block hash is a number obtained by performing a quadratic hash calculation on the block header. Is one of the block identifiers that uniquely and unambiguously identifies a block.

Block height

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

Transaction fee

The transaction fee is the transfer fee, which is related to the number of bytes taken up by the transaction, and is not related to the size of the transfer amount.

Mining difficulty

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