BTC wallet address generation of blockchain Wallet

1. Before developing wallet, we need to have the following preparatory knowledge
first, what is a wallet and its related categories? Xrv522 can develop blockchain wallets
from the perspective of developers, this article explains to readers how to interact with wallet and how to develop a wallet
How do we understand wallets? In short, it is an entrance to connect the blockchain. At present, mature public chains such as bitcoin and Ethereum have many wallets to choose from. Generally, the wallet needs full access to your user assets, that is, it will ask you to enter the private key. The evil cost of wallet is very low, which is one of the reasons why I suggest to choose open source wallet.

2. This is the order of importance: BTC private key, wallet security password, BTC address
the private key is everything and must not be told to anyone
as long as there is a private key, you can re import the wallet and reset the wallet security password
a BTC account can have many addresses, so the least important one is the address. No matter how unimportant, you can't just tell others.

3.

You can download a bitcoin wallet or register on a trading platform. Everyone's bitcoin address is unique. If you have an address, you can make a bitcoin transfer. Download bitcoin client or bitcoin wallet, you can also register your own bitcoin address. A bitcoin address is a string of 26 to 34 bits of letters and numbers, which looks a bit like garbled code

the bitcoin address is an indivial's bitcoin account, which is equivalent to your bank card number. Anyone can transfer bitcoin to you through your bitcoin address. The red box is the bitcoin address. Log in to my bitcoin bag and you can see the money

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

4. If anyone who has already bought bitcoin knows that the thing that looks like a pile of random code is the bitcoin address

a bitcoin address is a string of 26 to 34 letters and numbers
it looks like a lot of messy code. To put it bluntly, it's like your bank card number

By using secure encryption technology to store digital currency, you only need to have a contract address to transfer the currency. The function of this wallet allows you to put the currency in your wallet when you don't use it, which is higher than the security factor in the exchange

wallet is actually used as an address protocol, because all transactions on the blockchain are recorded in the whole network. Every bitcoin transaction to an address is recorded in the whole network and cannot be tampered with. When bitcoin arrives in your wallet, everyone can see the record to prove it

unlike most traditional currencies, bitcoin is a digital currency. Therefore, the method of this kind of currency is completely different, especially when it is obtained and stored. Because bitcoin doesn't have any physical shape or form, it can't be stored anywhere technically. Instead, it is the private key used to access your public bitcoin address and sign transactions that need to be stored securely. The combination of the recipient's public key and private key makes bitcoin transaction possible

there are several different forms of bitcoin wallets, which can meet different needs, and are different in security, convenience, accessibility and so on

paper wallet

a paper wallet is essentially a document that contains a public address and a private key that can be used to receive bitcoin, allowing you to spend or transfer bitcoin stored at that address. These are usually printed in the form of QR codes so that you can quickly scan them and add the key to your software wallet for transactions

paper wallets can be generated using services such as bitaddress or bitcoinpaperwallet, allowing users to create completely random bitcoin addresses and private keys. The generated document can then be printed, some of which offer tamper proof design, and even can choose to order holographic tags and use them

the main advantage of banknote wallet is that the key will not be stored in any place in digital form, which makes it completely free from hacker attacks. It can record the malware users hit and basically any form of digital theft. However, some precautions still need to be taken when creating wallets

obviously, before generating a paper wallet, you need to make sure that no one is watching you. To eliminate the risk of any spyware monitoring activity, it is recommended to use a clean operating system running from a USB flash drive or DVD, such as Ubuntu

in addition, once the paper wallet is set up, the website code should be able to run offline, which allows you to disconnect from the Internet before actually generating the key. Finally, use a printer that is not connected to the network

in addition, it is very important to know that you are printing valuable personal information on a piece of paper. Therefore, you need to take some measures to protect that piece of paper. For example, it is suggested to put it in a sealed plastic bag to prevent water stop, moisture and general wear. Some people like to laminate it and store it in a safe, storage box or entrust a lawyer to handle it

physical bitcoin

physical bitcoin usually preloads a fixed number of BTCs, and the intention is that as long as the private key remains hidden, it cannot cost its value. This is usually achieved by implementing tamper proof seals

bitbill's first proct was like a credit card, but most of its subsequent substitutes were shaped into a round medal. Mike Cadwell, a cryptocurrency enthusiast nicknamed "casascius", created the first popular casascius physical bitcoin in 2011

the private key is hidden under the strippable hologram, and when it is removed, it leaves the tamper proof mode. In exchange, the coin lost its numerical value. Since then, there have been several new coin makers

physical bitcoin is a very convenient way to store your funds more safely, which is very useful in offline transactions. Most importantly, they have recently become a valuable collection. However, the main drawback is serious security issues

in November 2013, Mike Cadwell was asked to stop the operation of the financial crime enforcement network because his work was considered to be a money sender. The rules of the campaign were so overwhelming that he had to stop selling items containing digital bitcoin. Since BTC is still a legal gray area in many countries, these items may even be considered counterfeit by the authorities

mobile

BTC is an indispensable tool for those who actively use bitcoin every day to pay for goods or trade face-to-face in stores. It runs as a smartphone app, stores your private key and allows you to pay for things directly from your phone

in addition, some applications enable users to use their smartphone's near-field communication function, which means that they can simply click on their phone to oppose readers without having to provide any information at all

any complete bitcoin client needs to access the whole blockchain ledger, which is growing and needs several thousand megabytes of storage space. Therefore, mobile wallet uses simplified payment verification (SPV) technology. They only apply to a very small subset of the blockchain and rely on trusted nodes in the bitcoin network to ensure that they have the correct information

although bitcoin storage is a convenient mobile solution, mobile wallet is vulnerable to hackers. In addition, if someone just accesses your mobile device, you may lose control of the wallet. There are a variety of bitcoin wallet applications running on Android devices. Apple banned bitcoin wallets from the app store in February 2014, but withdrew its decision a few months later

Web wallet

Web wallet stores your private key on the server of the company providing such service. The server is always online and controlled by someone else. Different services provide different functions, some of which connect to mobile and desktop wallets to your address on the device you own

very similar to mobile wallet, e-wallet enables users to access their funds anytime, anywhere through any device connected to the Internet. But unless implemented properly, the organization that runs the site may access your private key and take full control of your money. In addition, some e-wallets operate on the basis of exchanges, and some exchanges close down and escape users' funds

Desktop wallet

Desktop wallet has been downloaded and installed on your computer, and your private key is stored on the hard disk. By definition, they are more secure than online and mobile wallets because they do not rely on third parties for data and are more difficult to steal. They are still connected to the Internet, which makes them inherently insecure. But desktop wallets are a great solution for those who trade a small amount of bitcoin from their computers

Desktop wallet has many different choices to meet different needs. Some focus on security, some focus on anonymity, etc

Hardware

Hardware wallet is a unique bitcoin wallet, which can store the user's private key in a secure hardware device. This is the safest way to store any amount of bitcoin, and there is no verifiable event that money is stolen from the hardware wallet

unlike paper wallets, paper wallets must import software at some time, and hardware wallets can be used safely and interactively. In addition, they are not affected by computer viruses, and the stored funds cannot be transmitted to output devices in clear text. In most cases, their software is open source

some hardware wallets even have screens, which adds another layer of security because they can be used to verify and display important wallet details. For example, the screen can be used to generate recovery phrases and confirm the amount and address of the payment you want to make. Therefore, as long as you invest in a real equipment with good reputation made by a reliable and competent manufacturer, your funds will be safe and reliable

bitcoin wallet and security

possible problems:

capture malware. Malware can scan your disk and find your private key. In a few seconds, all your bitcoins will disappear. Trojan can encrypt all the files on the hard disk. After that, it may find all the links to your wallet, realize how much money you have and ask for the exact amount of bitcoin to decrypt your hard drive

virtual exchange can use your money to escape. You can lose the laptop or mobile phone on which the wallet is installed

suggestions:

< UL >

avoid using any wallet that needs Internet connection; Please use the refrigerated option instead

check everything carefully. For example, you can receive an email from blockwallet, but it's actually from blockcwallet, and if you authorize, your bitcoin will disappear immediately

First of all, you should imagine a concept of "wallet" in your brain. Your bitcoin is in your wallet. A wallet can contain many... Many addresses. The form of the address is the form

with the bitcoin address generated in the bitcoin wallet, you can receive bitcoin from others, and you can also transfer the bitcoin in your account to the bitcoin address of others. Bitcoin address, like bank card number, has the functions of payment, transfer and withdrawal. However, when transferring money, you can only transfer money by knowing someone else's bitcoin address

if we simply compare a bitcoin wallet to a bank card account, then the address of the bitcoin wallet can be regarded as a bank card account number. The difference is that bitcoin addresses can not be stored on the network, but also exist independently of your wallet

< H2 > extended data:

bitcoin address is a string of 26 to 34 letters and numbers. It looks like a lot of messy code. To put it bluntly, it's just like your bank card number. All transfer records of each bitcoin address can be checked through blockchain query, which is open and transparent

address generation of bitcoin Wallet: 256 binary digits are randomly selected to form the private key, and then the address is generated by encryption function. This generation direction is unidirectional. That is, you know that the address cannot be decrypted to calculate the private key. At present, the computing power of human computer can't be cracked, so you can publish the address on the Internet with ease

Let's talk about why we are not afraid of deception, because every mine or mining must have a leader, right? So you will be given the appropriate currency every day when you sign in or answer questions. For example, if you sign in, you will get 0.4 answers and you will get 0.08 answers. Generally, they will increase the value of currency. If you have two handsets or one mobile phone, you can download and register two mobile phones every day, which is about 1 Ordinary fake mining with indivial coin usually costs about 10 yuan or more, so now I'm going to analyze why you're not afraid of his scam

< UL >

you can start with the coin every day, generally you can sell yourself with an active value. If you sell a coin in three days, it's about 10 yuan. If you sell two mobile phones, it's more than 20 yuan in three days, that's 7 yuan in a day, and there are so many scams You can add a few more mining areas, right? Anyway, sell them in time. Do you still care if they are harvested

it's a scam that I've worked hard to develop for a long time. As a result, I just have a big income and the platform has run away, so it can't be generalized. It depends on how you judge it.

if it's all such scams, I like them very much, because I have three mobile phones and 10 such platforms a day. It's 70 yuan a day. Anyway, it doesn't take much time. In fact, it depends on you How to deal with my group, you can roll it together

(Liu Jiuliu's meaning) of course, Xiao still has to identify the feasibility of some
