Use the blockchain explorer to find out the real status of the transaction.

Everyone has basically used a browser, Google Chrome, 360 browser, etc...

The purpose of our browser is basically to retrieve specific information on the Internet, for example, open a certain browser, enter bitpie.com... and it is amazing to retrieve a pie.

Through the browser, you can have a panoramic view of the information you want to look up in your daily life, and all kinds of certain information also give you enough sense of security in your life.

And in the blockchain world——

"Where did my coins go?" "Why didn't I receive the money you transferred to me? " "Where is this coin now?" "...This kind of questioning in circles has actually become the norm for most users.

So how can you make yourself feel confident and full of security in the blockchain world?

"Lend me a pair of insightful eyes, let me see this disturbance clearly and clearly~" (Does this song reveal your age)

1. What is a blockchain explorer?

First of all, the "blockchain" is essentially a database, which is characterized by openness, transparency and traceability. So how to conveniently view various public data of the blockchain? The blockchain browser is used here.

2. What is the use of blockchain browser?

There are too many information that the blockchain browser can query, such as when the new block was dug out, what transactions are in the new block, and the rewards given by the new block...the content is diverse and interesting.

Sometimes the market software will remind XXX big account address to transfer 10,000 BTC to XX exchange. This is actually the program monitoring block data, which is essentially the same as manually querying data with a blockchain browser.

However, the most common and helpful scenario for ordinary users is to query the transaction status, such as whether the current transaction has been issued, whether the issued transaction has been confirmed by the block...

Let me give you a specific example. You withdraw 1 coin from Exchange A to your wallet, but the wallet is not displayed. At this time, the exchange shows that the withdrawal is successful, but there is no movement in the wallet...

3. How to use the blockchain browser?

As mentioned above, the most common and helpful scenario for ordinary users of blockchain browsers is to query transaction status. Let's mainly talk about how to check the status of a transaction.

First explain a noun: transaction ID (also called transaction hash). This is the key to querying the transaction status. Because each transaction has its own unique transaction ID, which is like the ID card of this transaction, through which we can find the corresponding unique transaction.

The following string is a transaction ID,

160c42ce6cfe0f1bd3fbdb220b7655b0e848061f759c6dc38eb06f6d206f3c51

Generally, after issuing coins in the wallet or withdrawing coins on the exchange, you can see such a string of characters in the details.

With the transaction ID, you can walk sideways in the blockchain browser. You only need to put the transaction ID in the search box of the blockchain, and you can find many statuses of the transaction.

After the query, you will have the confidence to fight with the exchange and the wallet. If the ID given by the exchange cannot be found, it is the exchange’s problem. If the blockchain is confirmed and the wallet is not displayed, it is the wallet. question. So everything is based on blockchain data, don’t forgive some wallet editors just because they are popular.

A few more situations:

The transaction ID cannot be queried. This situation is generally caused by the issuer not broadcasting the transaction. If the blockchain shows the data but the wallet does not, this is generally a problem with the blockchain data synchronized by the wallet. The wallet itself is a tool for reading blockchain data, so display problems will not affect security, and if the blockchain is confirmed, your assets are safe.

4. Is the blockchain browser safe?

As an ordinary web page that only provides data retrieval function, the blockchain browser is no different from the (healthy) web pages you usually browse, and will not involve the security of your blockchain assets.

5. Does each currency have its own blockchain explorer?

no. Blockchain browsers need to be developed independently, but some blockchain browsers are developed by the project team itself, and some are developed by third-party teams or supporters.

Therefore, there are some niche projects that cannot find a blockchain browser.
