First of all, the "blockchain" is essentially a database, which is characterized by openness, transparency and traceability. So how to easily view the various public data of the blockchain? This is where the explorer blockchain comes in.
The blockchain browser is actually a website that can query blockchain data. Through him, we can query the transaction details on the blockchain, the network status, and everything about the blockchain data.
Second, what is the use of blockchain browsers?
There is so much information that the blockchain browser can query, such as when the new block is dug up, what transactions are in the new block, and how much the new block gives the reward. The content is varied and interesting.
The market software sometimes reminds XXX large address to transfer 10,000 BTC to XX exchange, which is actually the program in monitoring the block data, and the use of the blockchain browser to query the data is essentially the same.
However, the most common and most helpful scenario for ordinary users is to query the transaction status, such as whether the current transaction has been issued, and whether the issued transaction has been confirmed by the block.
For A specific example, you mention 1 coin in A exchange to the wallet, and then the wallet does not show, at this time the exchange shows the successful withdrawal of coins, but there is no movement in the wallet.
In this time called every day not working, called the ground should not be the moment, with the blockchain browser can check the real state of the transaction. It is clear whether the transaction is really issued or not issued at all, whether it is the exchange's problem or the wallet's problem.
Third, how to use blockchain browser?
As mentioned above, the most common and helpful scenario for the blockchain browser for ordinary users is to query the transaction status. Let's focus on how to check the status of a transaction.
Let's start with a noun: transaction ID (also known as transaction hash). This is the key to checking the status of the transaction. Because each transaction has its own unique transaction ID, just like the ID card of the transaction, through which we can find the corresponding unique transaction.
The list below is a transaction ID,

Generally, after issuing coins in the wallet or withdrawing coins in the exchange, such a string of characters can be seen in the details.
With the transaction ID, you can walk horizontally in the blockchain browser. Just by placing the transaction ID in the search box of the blockchain, you can find out a lot about the status of the transaction.
After the inquiry, you will have the confidence to quarrel with the exchange and the wallet, if the ID given by the exchange can not be found, it is the problem of the exchange, if the blockchain is shown to confirm, the wallet is not shown, it is the problem of the wallet. So everything depends on the blockchain data, and don't forgive him easily because some wallet Xiaobian is popular.
Here are a few other things:
Unable to query the transaction ID, this situation is generally caused by the issuer has not yet broadcast the transaction. If the blockchain shows the data but the wallet does not, there is a problem with the blockchain data, which is generally synchronized by the wallet. The wallet itself is a tool to read the blockchain data, so the display issues will not affect the security, the blockchain confirms that your assets are safe.
There is no security risk in exposing the transaction ID, but some privacy is lost, because others can also look up your transaction details through the transaction ID. It depends on whether you want to share your trading ID with others.)
Are blockchain browsers secure?
The blockchain browser, as a normal web page that only provides data retrieval functions, is no different from the (health) web pages you normally browse, and does not involve the security of your blockchain assets.
But one thing is still nagging: no matter what website you land on, as long as you enter a mnemonic and private key behavior, immediately shut it down and curse out of respect.
Does each coin have its own blockchain browser?
Not really. Blockchain browsers all need to be developed separately, but some blockchain browsers are developed by the project team themselves, and some are developed by third-party teams or supporters.
So there are some niche projects that can't find a blockchain browser.
In addition, most of the tokens on the market are issued based on Ethereum and EOS, and the query function on the blockchain browser of Ethereum and EOS can also be applied to these tokens
- Are blockchain browsers completely trustworthy?
Not really. Because the blockchain browser is just a tool, it is possible to have abnormal situations. If you feel that your query data is abnormal, it is recommended to search and compare it on multiple blockchain browsers at the same time.
