What is the sub address of bitcoin
the wallet of bitcoin is based on the HD (hierarchical certainty) framework, which has the methods of generating different addresses and managing addresses. Each public address of your wallet will be generated from your wallet's xpub (extended public key)
if you use the same address every time you receive a BTC, anyone can easily track all your payment records. This address generation method improves privacy by generating a new address (sub address) when you collect money

public key and private key are terms in asymmetric encryption of modern cryptography. They usually encrypt information with public key and decrypt information with private key. Why? Because when you watch TV dramas, telegrams are encrypted symmetrically. The disadvantages of this encryption method are obvious. If someone knows the key and encryption method, they can decrypt the telegrams according to the encryption method. Until asymmetric encryption, the situation has changed. Public key is the key that can be made public all over the world. For example, when you communicate with Google, you encrypt with the 1024 bit public key given by Google and send it to Google. Only he has the corresponding private key, and only he can decrypt it, so the communication security is ensured
2. Bitcoin mainly uses ECDSA, which is the elliptic curve signature algorithm, This algorithm has two characteristics. Note that these two points are very important to the following
A. as long as you know the private key, you can calculate the corresponding public key
B. If you have signed something with the private key, you can use the public key to calculate whether you signed it or not
3. After knowledge preparation, let's start with the transaction of bitcoin. In fact, bitcoin has no wallet, only transaction bills, and the whole bitcoin is a lot of transaction bills
for example:
bill 1 transfers from a to B to XXX bitcoin
Bill 2 transfers from B to C and D to XXX bitcoin
bill 3 transfers from C to e to XXX bitcoin
.... Anyone who downloads the client can receive all the bills from the day when bitcoin was established, so as long as all the bills are downloaded, they will naturally know how much money should be left on each account (think carefully here)
4. The account of bitcoin is the public key mentioned just now
5, Here is the core part!!! Each bill is a piece of data. After you sign it, it will be sent to the whole network, and the data structure will be reversed into easy to understand Chinese. The explanation is as follows:
from (who sent it, including two parts)
previous TX: the ID of the bill for which you want to spend the money, that is to say, any money you spend should have been transferred to you, You need to show the ID of the bill
scriptsig: your signature for this transaction is to hash the bill with your private key, only you can do this hash
to (who accepts, including two parts)
value: how much to send
scriptpubkey: the public key of the other party, and the bitcoin account is a public key
6, How to send it? Bitcoin communication is not so complicated. You can compare it to IRC channel, but different from ordinary "IRC", any client is an "IRC" server. When you start the client, you will receive the client address with public IP around, that is, the "server" list. This list is constantly refreshed, and it is all other bitcoin users, So when you shout a word in this "IRC", people around you will hear it and spread it all over the world
7. After sending the signature to the whole world, all the clients who receive this list will verify whether your signature is correct, whether you sent it, and whether you have so much money (according to the historical transaction, you can calculate how much money you have to spend)
if you have calculated this transaction, it's OK, Basically, the transfer is successful
8. In fact, the other party has accepted bitcoin, but in order to spend it, he must have the private key corresponding to the address (public key). So he can fill in the from header of a form. Previous TX is the serial number of the transaction just now. Scriptsig fills in the hash signed with his private key...
