1. I'll give you my address (address). You can find my zip code (public key). You can write to me with my zip code (public key) + address. The mail will be sent to my mail cabinet. I'll open the mail cabinet (private key) with the key I have. The key of express cabinet is stored in my wallet (wallet)
1. The mail cabinet is stolen (the database is stolen)
2. The key is stolen (the private key is stolen)
3. Knowing my home address (the public key is stolen), the lock of the mail cabinet is opened violently (the private key is cracked violently).

2. First of all, let's talk about the background. The basic principle of bitcoin "account" is key public key address. You can roughly understand it as "key box box number". Now is to start from the box number or box to crack the key
there are basically two kinds of attacks, one is dictionary attack, the other is brute force attack
dictionary attack is to use common passwords and their simple variants as keys one by one. As long as your pass phrase is not hard enough, the possibility of successful attack is very high. So if you want to use this, you need to popularize the knowledge of cryptography first, and don't think it's very safe to add a long password
if you don't use the wallet generated by pass phrase, you can only crack it violently, which is equivalent to enumerating all the possible keys. At present, this is impossible, even if the electronic computer is becoming more and more powerful. However, quantum computer can do it theoretically, but don't worry too much. If such a powerful quantum computer comes out, it will not only endanger bitcoin
at the same time, bitcoin has a second layer of protection: if an address only accepts bitcoin but does not output it, its public key is confidential, that is to say, no one else can see the box, only the box number. At present, the process of decing the box from the box number can't even be done by quantum computer. In other words, if there is a quantum computer, bitcoin has a last line of Defense: it's temporarily safe to transfer your money to a new address
finally, some time ago, the wallet generated by the Android client was attacked because of a bug in the underlying random number generator. In fact, this function is not random securerandom, which Google quickly admitted and fixed. It's hard to say whether this kind of thing will happen again, but I don't think we need to worry too much.

3. How to choose BTC wallet and how to store your bitcoin? This is an important problem that every bitcoin user must face. Bitcoin gives you more freedom and power to control your money. But if you are not careful, it may bring disastrous losses. If you choose to remain in complete control of your bitcoin on your own, then there is no one who can stop you from doing something stupid and pay for your mistakes. There is no bitcoin company to call and try to convince your legitimate owner of your address so they can give you the key back. However, there are friendly and secure services based on bitcoin, or intermediate solutions, which can let users avoid the risk of operating wallets. The purpose of this article is to explain what different options you have for storing BTC, so that each user can make the right choice between security and control. Wallets fall into two main categories: Online wallets online wallets are by far the easiest way to access your bitcoin from any computer. But there needs to be enough trust in wallet service providers. Currently, there are four main choices for online Wallet:

7. The private key is a secret data block that proves that you have the right to consume bitcoin from a specific wallet. It is implemented through a cryptographic signature. If you are using wallet software, your private key is stored in your computer; If you are using an online wallet, your private key is stored on a remote server. Don't disclose private keys, because they allow you to consume the bitcoin in the corresponding bitcoin wallet
digital currencies such as Ruitai, doggy and Wright all have private keys.

The theft of 14.5 million bitcoins in Jiangxi Province was solved, which caused heated discussion among netizens on the Internet. We all know that the current era is an Internet era, and it is also an era of rapid development. There are many people who want to earn money through illegal means, which is not worth advocating. We also hope that everyone can learn this lesson, suspects will also face very severe punishment
we also hope that this lesson can arouse a wake-up call for everyone. If everyone is like them, they will certainly face the disaster of imprisonment. At the same time, we need to pay attention to the fact that no matter how powerful the hacking technology is, there will still be many hot spots left. After all, it is the body, which cannot be separated from legal sanctions, I also hope that they can learn from this lesson, be a good person in their future life, and never violate the law and discipline. I hope everyone can pay attention to this
