『一』What is the relationship between blockchain private key, public key and address?

The relationship between blockchain private key, public key and address is private The key generates a public key, and the public key is converted into an address. So the private key is the most important. The three are irreversible. The address cannot generate a public key, and the public key cannot be converted into a private key.

The blockchain address is again, which usually consists of a string of letters and numbers of 26 to 35 characters. The blockchain address is mainly derived from the public key, block The chain address is equivalent to the bank card number we usually use. It can be disclosed to anyone with no security restrictions. Its main function is to receive and send digital assets on the blockchain.

Blockchain technology is now in its early stages of development, but because of its decentralization, security, non-tampering and other characteristics, it may have killer-level applications in life and work in the future and has attracted much attention from various countries. Pay attention to. This article is for reference only, please leave a message for discussion.

『二』How to view the blockchain assets (digital currency) of the address through the blockchain asset address (digital wallet address)

You can view it with a blockchain browser .

Enter the wallet address you want to query in the search input box. If the address you enter is incomplete, but this address has previously conducted ETH transactions or been queried on the blockchain, then the input box will Automatically complete the address you query.

Click "Query" and all the information about this wallet address will appear.

Click "Transaction Hash" to see the details of the transaction.

The principle of blockchain browser query:

Because the transaction information in the blockchain, etc. The data is open and transparent, and the blockchain browser is an address for querying blockchain transaction records. Users can use it to view their own transaction information and other information stored in the blockchain.

The vast majority can be checked, which is a major feature of the openness and transparency of the blockchain. Addresses are transparent. As long as there is an address, you can check its transfer in and out.

A friend mentioned the anonymous currency, so I won’t go into details. In other aspects, it is also a tool to check the authenticity of the project. Some funds under the guise of blockchain issue some coins to deceive investors. You can go to the browser to take a look. Sometimes there is no data on the chain at all, which proves that the points are issued by themselves.

『三』 [Blockchain] What is a Bitcoin address

A Bitcoin address is a 26- to 34-digit string of letters and numbers, which looks a bit Like gibberish. But it is your personal Bitcoin account, equivalent to your bank card number. Anyone can transfer Bitcoin to you through your Bitcoin address.

Unlike the Bitcoin private key, it will not cause the loss of Bitcoins due to information leakage, so you can safely tell anyone your Bitcoin address.

You can view all transfer transaction records of each Bitcoin address through the blockchain browser.

Commonly used Bitcoin blockchain browsers include:
https://btc.com/block
https://www.blockchain.com/zh-cn/explorer

Our commonly used Bitcoin address formats generally include the following four types.

1. BASE58 format
BASE58 format is a common Bitcoin address format, usually starting with 1.

For example:

2. HASH160 format
The HASH160 format is the result of calculating the SHA256 signature of the 130-bit public key using the RIPEMD160 algorithm.

For example:

3. WIF compression format
WIF compression format is the wallet input format. It is the result of compressing the BASE58 format into a 130-bit public key format. This is the most The original Bitcoin public key calculated by the ECDSA algorithm.

For example:

4. 60-bit public key format
The 60-bit public key format is the result of compressing a 130-bit public key.

For example:

Bitcoin is based on mathematical cryptography. The great master Satoshi Nakamoto used the elliptical encryption algorithm (ECDSA) to generate the private encryption of Bitcoin. key and public key.

The public key can be calculated from the private key. The value of the public key will be used to obtain the Bitcoin address after a series of digital signature operations.

Bitcoin addresses are randomly generated by algorithms, so some people will ask, since they are all randomly generated, will Bitcoin addresses be repeated? Regarding this issue, there is probably no need to worry.

Because the length of Bitcoin’s private key is a 256-bit binary string, the probability that two randomly generated private keys are exactly the same is one in 2^256 ≈ 10^77. This number is as big as yours It is simply unimaginable that the probability is much smaller than winning the lottery; so don’t worry, everyone’s Bitcoin address is unique.

『四』What can you do if you know the blockchain address?

With the address, others can transfer money to you.
Blockchain address generally refers to wallet address. To put it bluntly, the wallet on the blockchain manages digital assets (what we usually call coins)Tools, the transfer in and out of your coins and the records of transfers in and out are all implemented through the wallet. Just like you need a home address when you go home, digital currency also needs a home address. The difference is that digital currency addresses are unique.
What is an address? In a blockchain system, the private key is generally a 256-bit binary string randomly generated by a special random algorithm, and the public key is generated from the private key through an irreversible algorithm, (i.e. You can only deduce the result from the initial value, but cannot deduce the initial value from the result), and the public key passes the address of the irreversible algorithm (Note: There are

3. ETH browser:

Can the "Lu" blockchain address be queried?

It can be viewed with a blockchain browser.
If the address you entered is incomplete, please enter it in the search input box The wallet address you want to query, but after this address has previously conducted ETH transactions or queries on the blockchain, the input box will automatically fill in the address you query.
Click query, and all the information of the wallet address will appear.
Click the transaction hash value to also see the details of the transaction.
The principle of querying the blockchain browser:
Because the transaction information and other data in the blockchain are open and transparent, the blockchain The browser is the address for querying blockchain transaction records. Users can use it to view their own transaction information and other information stored in the blockchain.
Most of them can be checked, which is a major feature of the openness and transparency of the blockchain. .The address is transparent. As long as there is an address, you can query the transfer.
