How does bitcoin transfer guarantee privacy

1. Computers with bitcoin clients are called nodes, and all nodes on the Internet constitute a bitcoin network. Whenever a new bitcoin is generated and traded on a node, the node will broadcast to the nearby bitcoin node, and finally the whole network node will record the transaction information
in the bitcoin network, each node with a client installed has a distributed database to manage bitcoin proction, transaction, query account balance records, and update and record the latest records of changes in the bitcoin system
when you want to send 10 bitcoins to your friends. You need two things, one is the bitcoin address, the other is the corresponding private key. Bitcoin addresses are different from bank accounts. You don't need to sign a bunch of documents to apply for them. They are randomly generated, just a string of letters and numbers. The private key is also a similar string, but this is strictly confidential. The bitcoin address is like a transparent piggy bank. Everyone can see what's in it, but only the person with the private key can open it.
after you send the transaction application, the surrounding nodes will check whether your account has 10 bitcoins. If there are, they will agree to the transaction, and broadcast the message to the nearby nodes, which will be transmitted from one to ten, and from ten to 100, Soon the whole network will confirm the transaction information and write it to the block. Your friend will receive 10 bitcoins, and the transaction will be completed.
if you want to send small bitcoins, in theory, digital currency can be cut infinitely. At present, the smallest bitcoin unit is called "Nakamoto Tsung", which is equivalent to 0.00000001 bitcoins.

2. Bitcoin is often used as an anonymous currency because it can send and receive bitcoin without providing any personal identity information. However, bitcoin itself is not 100% anonymous in most cases. Sending and receiving bitcoin is like publishing a work under a pseudonym. If an author's pseudonym is associated with their identity, everything they have written will be associated with them. For bitcoin, your anonymity is the wallet where you receive bitcoin. Every transaction involving the address will be permanently stored in the blockchain. If your address is connected with your real identity, then every transaction will be related to you, but reasonable anonymity can be achieved<

buy bitcoin anonymously

the first thing you can do is buy bitcoin anonymously

the first option is to buy them in cash to avoid completely online transactions. Most online transactions are similar, it requires you to upload your ID card. You can buy bitcoin with ATM cash or meet the seller in person“ In the section "we buy bitcoin with cash", there is more information about how to buy bitcoin with cash

the second best option is to buy them on virwox. It's not really completely anonymous, because you need to disclose some information, but it's still better than most bitcoin transactions that need to provide the required bank accounts and personal documents

you don't need anything here, you just need a free account for virtual transactions. With this account, you can buy another currency - Second Life Linden (SLL). You have different choices to buy Linden, such as PayPal and skrill. But considering that a good option for anonymity is Paysafecard payment, with Paysafecard you can buy bitcoin at any store. With Paysafecard, you can cash anonymous funds with your virwox even if you don't have an ID card, a bank account or a credit card. Then you can easily convert your second life Linden into bitcoin without verification

finally, you can get bitcoin through anonymous bitcoin loans

according to our experience, it is impossible to purchase bitcoin anonymously with a credit card

mix your bitcoin

if you already have your bitcoin, it is particularly important that bitcoin users can mix their transactions with other users by using mixers, so bitcoin mixers are also known as bitcoin "tumbling" or "foundry". It's the server that breaks the connection between you and your bitcoin account. Mixers mask the flow of your bitcoin from one address to the next. Although bitcoin mixers cannot guarantee 100% anonymity, they provide a very high level of anonymity

we recommend that you use high-quality online currency mixing services, such as bitcoin mixers or currency mixers, which can conct regular bitcoin transactions for users who cannot link to the original. To further enhance the security of transactions, they provide the opportunity to use two or more forwarding addresses and appropriate time to delay, so as to immediately delete all file log related transactions. You can also use sharedcoin because it's free, but it's a bit complicated. In addition, if you use anonymous tor browser, you may try bitconinfog

it should be noted that there are many fraudsters in providing bitcoin mixing services

bitcoin is usually stored in a software program called bitcoin wallet. If your wallet and your personal information are identifiable, the above information will not help you. If you want to maintain considerable anonymity when using bitcoin, such as paying for alt websites, then you should register at least one wallet with an anonymous account and one-time email address

you can also use different wallets for each transaction to avoid tracking you for multiple transactions. It's like maintaining multiple independent identities. A simple way to maintain multiple wallets is to use a simple and lightweight software wallet, multbit, which allows multiple wallets to be managed on a single software program

if you want to be more anonymous, we suggest that you make a bitcoin wallet. Perhaps an easier way is to use the code on bitaddress.org

the open bitcoin privacy project has released their first complete report on the privacy level of the bitcoin wallet that is not valid. The best and most hidden bitcoin wallet is darkwallet, and the second two wallets with good concealment are armory and mycelium

anonymous bitcoin debit card

e-coin is a British company that has launched a virtual and physical Visa debit card that can store bitcoin. To use this debit card, you need to pay a small fee at present

you can order credit or debit cards that are specified in US dollar, euro and pound sterling. All it needs is a valid email address and basic personal information to register. Once you request to register a debit card, it will be sent to your email address. But at present, e-coin has not provided bitcoin debit card service to the United States

you can use the e-coin credit card until you reach the limit. You can get an unverified card and use up to $2500. Once you reach the limit, you have to verify your identity - a certificate that scans your ID or passport and address, or order a new card. If you prefer MasterCard, bitgold and advancedcash debit cards are OK<

bitcoin transactions

bitcoin transactions are never truly anonymous and can be queried through blockchain (blockchain is a comprehensive database for recording bitcoin transactions)

almost all transactions require you to verify your identity by sending a scanned personal certificate, and you also need to report large transactions to government authorities. When you use bitcoin to pay for goods and services, you need to provide your name and address to the seller many times. This means that someone who wants to track your trading activities can use your ID card information to track your future trading activities or study your previous trading activities. All in all, it has damaged your security and privacy.

3.

If bitcoin accounts are decentralized, so are hackers. Bitcoin, which uses blockchain technology, is not more secure than bank accounts. On the contrary, it is vulnerable to hackers. So, in the world of virtual currency, how to protect the security of account funds

Secret your private key address

the bitcoin address is the only information needed to define the distribution and transmission end of bitcoin. These addresses are generated anonymously by the user's wallet. Once the address is used, all the transaction history related to it will destroy the confidentiality of the address. Anyone can view the balance and all transactions at any address. Because users usually need to disclose their identity in order to receive services or goods, the bitcoin address cannot be completely anonymous. For these reasons, it is better to use bitcoin address only once, and users must be careful not to disclose the address

When replacing the computer, try to destroy the hard disk of the original computer. Don't save or publish the private key of bitcoin to the cloud, mailbox or collection. If a network administrator writes a regular expression to retrieve the text, he can find all the information and crack the user's account

2. Stored in bitcoin wallet

many bitcoin exchanges have been attacked by hackers. If you use the wallet of bitcoin exchange, please use Google's "double authentication" to ensure security. During the development of virtual currency, there have been many cases of bitcoin exchange running away. The exchange owns the private key of the user's wallet, which is not a safe way to save bitcoin

bitcoin wallet has a wide range of customers, which is more secure than the wallet service of bitcoin exchange. No matter what kind of wallet you choose, you should choose a strong password. Don't use the same password as the registered email. At the same time, do not put eggs in the same basket, choose multiple storage ways to improve the security of assets

using the genuine system of bitcoin wallet, regularly updating security vulnerabilities and fixing bugs can improve security. Some studies have pointed out that IOS system is more secure than Android system, because the existing security vulnerabilities of Android system may be relatively easy to be attacked by hackers

3. The most common way to identify phishing sites is phishing sites. Hackers will create a domain name similar to bitcoin website, which may be sent to users through e-mail and other channels. Once users try to log on the website, hackers will record their login information

so be careful before clicking any link. Many browsers have the service of "phishing check". If you carefully identify the domain name of the website, you can identify the phishing website

4. Guard against Keylogger

in addition to phishing sites, the common attack method of hackers is Keylogger. Keyboarding is the easiest way to capture passwords. The deception of key recording software is very high, even the technical house may believe it. In short, a keyboard recorder is actually a script code. Once it is installed on the operating system of the target computer, it will record all the keystrokes on the keyboard and send them to hackers, mostly through FTP

the successful method of introcing Keylogger depends on many factors, including the operating system, the lifetime of keylogger and the anti infection level of target computer. Keyboard recorder is usually injected through web browser. The security vulnerability of the target machine depends on the type of browser it uses; Whether the operating system installed on the target machine is genuine, and whether the operating system is updated with the latest security vulnerabilities and bug fixes

5. Watch out for USB theft program

the software will retrieve your password and login credentials stored in the browser. Once FUD, some stealing programs can be very powerful. In most cases, a steal program is a. Bat file, which can be injected into the target machine online or driven by USB

6. Using proxy and VPN

proxy server and VPN can increase the security of your bitcoin wallet, although most people mistakenly believe that VPN makes them anonymous online. But in fact, VPN only improves the privacy of users. VPN can rece the possibility of hackers accessing the router to open the port, which also means that they are less likely to succeed

7. Encryption and backup wallet

wallet backup is essential to prevent losses caused by computer failure or human error. If a computer or mobile phone is lost, a backup wallet can help retrieve the bitcoin. At the same time to encrypt the online backup, any backup that can be accessed through the Internet should be encrypted

how to back up your wallet? First, close the bitcoin client, then select the backup wallet of the menu file in the main interface, and the wallet.dat file to other hard disk partition, mobile hard disk or U disk

it should be noted that the entire wallet should be backed up, not just the private key. Bitcoin wallet has many private keys for receiving transaction change. If only the private keys of visible bitcoin addresses are backed up, most of the funds may not be restored from the backup. Also, back up your wallet regularly to make sure that all recent bitcoin change addresses and newly created bitcoin addresses are included in the backup

Cold storage

offline wallet is called "cold storage", which is the safest way to save digital currency

cold storage is an offline wallet that is not connected to the network, that is, it will not be attacked by black horse and Trojan horse. However, because the operation is relatively complex and the price is relatively expensive, the price of offline wallet is more than 1000 yuan, which is suitable for users who have a lot of bitcoin and are ready to hold it for a long time

although the operation of cold storage is relatively complex, it is the safest storage method. At present, only cold storage has truly realized the inviolability of personal assets and is not subject to the supervision of others

4. Bitcoin China is currently the world's largest bitcoin trading market,
is safe and can be traded with confidence
in addition, you can also trade on bitcoin website. Besides bitcoin, there are many other virtual currencies, which can diversify investment

5. It's five seconds. This requires an internationally recognized RTXP Internet financial agreement to enable quick global transfers. The radar currency is international Alipay. Bitcoin does not have the function of quick transfer

6. At the beginning, mmm financial community high interest fraud regulation: against the law
time: 2015 place: Beijing
recently, in the name of "financial mutual assistance", many places in China promise high income and lure the public to invest money; Mmm mutual financial community, Morgan currency, Baichuan currency and so on are more frequent. The China Banking Regulatory Commission (CBRC), together with the Ministry of instry and information technology, the central bank and the State Administration for Instry and commerce, issued a risk warning that this kind of operation mode violates the law of value, and the fund operation is difficult to maintain for a long time. The public should invest rationally and prudently.

7. The H-series is a full-scale traditional SUV with small displacement and weak power< At present, the H3 of the H series has a large population, and the Honda CRV is not demanding on cross-country ability.
the capital is limited, and the high configuration can reach 20W.

two SUVs in the traditional sense are preferred.
the capital is abundant (with 30W budget) to pursue comfort? What is the budget? For off-road, H5 is about 14W at the lowest, and small cars borrow what great wall calls "mini SUV"
Haval H-series currently has H3 and H5, M2 has more than 9W at the highest skylight version
H-series H3 has more than 9W at the lowest configuration, so the fuel-saving price is lower than H-series, and the later maintenance is more economical
compared with H-series, the natural space is smaller, Sales volume ranked first this year, leather rable

the price of the two series is not comparable, respectively, said
M series of the cheapest M1 have less than 5W

Harvard M series is mainly a mini car. If you want to meet your own needs, you must buy the H3, and you will never regret buying it.

if it's just a city car, you can't buy it

8. mining in order to rush up the sub magic glove mining plus 5 is necessary, which can save you a lot of time. First of all, it's necessary to explain. I don't think it's necessary to take a mining map to find it. A map is not big enough. You can find out where to brush it if you visit it twice. If you blindly pursue mining by mining map, you may be misled. There is also the practice of mining to take less time to practice, such as 2 o'clock in the evening, ha ha. Before 75, you can go outside the main city to mine copper and smelt copper. After 75, you can go to the map above the barren land. Copper mining and tin mining have smelted bronze until 125 (if FM + 5 to 120 is OK, it's the same at the back, you can leave 5 o'clock in advance). This is a difficult stage. Don't speculate and want to find a fixed place to brush silver, That would be futile. 125. The recommended location is arahi highland. Turn around the surrounding mountains. If you have a hole, you can enter it. If no one grabs it with you, it won't take long to reach 175. The recommended place for collecting Mithril is wasteland or cintland, both of which are Mithril paradise. If someone grabs it from you, change it to another map. It's also around the mountains. It's important to note that there is a cliff on the far right side of singland. Don't fall down. If you don't fall down and you're not dead, I suggest you drown in the water and resurrect directly. In these two places, 250 is the best. The recommended location for silver mining is burning plain or feywood. There are several ore brushing spots in fat man cave, but it's not easy to find out which cave it is in. Therefore, if you are not familiar with the situation in the cave, it's recommended not to mine it. Just go around the mountain. These two places don't need to stay for long. Just go to 275. 275 the wormhole of hilisus, the recommended place for collecting silver from fuser, is absolutely paradise. As long as you choose the time to rob no one, it will soon be 300. The key is to be familiar with the wormhole map. Or you can choose to go to Dongquan Valley, where there are many rich mines, but the map is too big to run. 300 magic iron ore Hellfire Peninsula, turn around Hellfire, if you have big birds, of course it will be quite fast. Again, don't believe in the distribution map of mineral deposits. Your memory is better than anything else. It's only 330 here. Daofeng mountain, 330 Jingjin mine, is really a paradise for miners. You can graate here

9. The answer is quite a few, but not many to the point
the motherboard supports PCIe × 16, the problem is not big, in theory, the mainstream of the lower end graphics card can be used. But considering your weak small power supply, 96gso can be directly ignored. The rating should be more than 230W. The TDP of your original whole system is about 200W. Is the rating 230W? Brand machine in this respect usually (I mean usually ~ ~) will not shrink, the rating should be above 250W. The old 65nm and 55nm cards will not be considered. We recommend the enhanced version x2
of YinChi GT220 http://detail.zol.com.cn/vga/index216225.shtml
tdp60w is not available, so it is affordable and the price is reasonable
the performance is better than 95gt and 4650, slightly inferior to 96gso G94 and HD4670. It's enough for your U. And this kind of low-end small card, the size will not be very big, card body is quite short, HTPC small chassis is no problem, you can absolutely plug in.
