Anonymity of blockchain

1. The anonymity of digital currency market is still there, which is also very popular. Although bitcoin has anonymity, its anonymity is not particularly good. Zcash is similar to bitcoin in many ways. First of all, it is also based on the distributed ledger (blockchain) for transactions. But there is one big difference between zcash and bitcoin: zcash is completely anonymous
according to the introction, zcash uses a technology called zero knowledge proof (known as "ZK snark") to verify the authenticity of the transaction. It uses a public blockchain to display the transaction, but it will hide the amount of the transaction. Viewing the owner of the key (i.e. the owner of the coin) allows others to view the information associated with the key
in short, this method of calculation allows users to prove that they have the currency they want without exposing information about where the currency came from or is going. It's like zero knowledge proof allows you to enter a password on a website and verify it by the website's server without actually transmitting the password
in contrast, although bitcoin and other digital currencies are famous for their concealment of transactions, in real life, they can often track transactions through the records of ordinary bitcoin blockchain, so that people can accurately know the sender and sending location of bitcoin. Nowadays, zcash has realized the transaction of original data in the form of encryption, rather than publishing the transaction data to the public like bitcoin. Snowden also said that the anonymous zcash project can solve the monitoring risk of bitcoin
therefore, zcash, an anonymous function that pursues the ultimate privacy protection, is first considered to have great value in the financial instry. Foreign media pointed out that the traditional financial instry has an extraordinary demand for information protection. Although many people think that the privacy requirements of bitcoin and other blockchain systems come from crypto anarchists and liberals, the fact is that the traditional financial instry is promoting the hiding of transaction information on the blockchain
however, the anonymity of digital currency is also a headache for the regulatory authorities, and it is very difficult to popularize it in the world. At most, it is only a niche proct. However, the platform developed by using blockchain technology has great potential. For example, the blockchain content publishing platform decent, Ethereum's intelligent contract and so on.

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. Rutgers University, a public research university in New Jersey, is concting a new study to show that bitcoin trading is not entirely privacy centric as people think
in fact, bitcoin can't help much in terms of anonymity. If you just want to pursue anonymity, it's better to use cash, which is the most anonymous means of currency trading, and its source can't be traced at all
bitcoin is a protocol, and transactions are broadcast to the distributed public ledger (blockchain). Everyone in the world can view the ledger in real time, track the transaction from the source to the destination, and do not need to register for authorization. It can be said that this has broken anyone's illusion of using bitcoin to seek privacy or anonymity
zero currency is the most anonymous digital currency in the world. However, all transaction information will be recorded on the blockchain, and the information on the blockchain is open and transparent. The digital currency issued by Puyin group is based on blockchain technology.

4. The analysis of jinwowo network is as follows: because the exchange between nodes follows a fixed algorithm, so the counterparties do not need to make the other party trust themselves through public identity, which is very helpful for credit accumulation.

5.

A: the basic characteristics of blockchain

I. decentralization
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage

Second, openness

the foundation of blockchain technology is open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

Third, independence

based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

Four, safety

as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity

unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information transmission can be anonymous

6. On October 22, 2013, Qiao from Dongyang searched GBL company, a bitcoin trading platform, on the Internet, and recharged 90000 yuan to buy and sell bitcoin through a third-party payment. On October 26, Qiao found that the staff of the network trading platform were not online, and some normal trading proceres could not be implemented, and then reported the case to Dongyang Public Security Bureau
Dongyang Public Security Bureau of Zhejiang Province immediately started the investigation and found that Qiao was not the only one who suffered losses. Through efforts, the police of the special task force determined the identity of the manager of the GBL trading platform and implemented the pursuit in time. The first case of fraud on bitcoin trading platform in China was solved
lawyer analysis:
Zhang Yanlai, senior special researcher of China e-commerce research center and lawyer of Zhejiang Jin law firm, believes that virtual currency is not a new concept. Q-coin and online game currency have long been known by people. However, the emergence of bitcoin once again makes people realize the power of virtual currency. Compared with the traditional q-coin, the biggest feature of bitcoin is that it does not have a unified issuing agency. The generation of bitcoin completely depends on computer algorithms, and anyone can participate in the issuance of bitcoin
this makes it difficult to trace the source of bitcoin, which makes it a real virtual currency. The anonymity, cross-border and other Internet genes of bitcoin make people see a new form of currency that may circulate in the future society, so the pursuit and use of bitcoin also continued to rise in 2013. Some foreign governments have recognized the legal status of bitcoin. In China, some online stores have begun to use bitcoin for trading. Restaurants that accept "bitcoin" consumption have appeared in Beijing. The first "bitcoin" investment fund in China is also being raised. After the Ya'an earthquake, one foundation has received a total of 65 bitcoin donations, with a market price of about 50000 yuan
of course, money laundering, fraud, gambling and so on will follow. This case is a typical case of fraud under the banner of bitcoin trading. As the first case of bitcoin fraud in China, the public security organs have also concted in-depth study and understanding of the professional knowledge related to bitcoin, and finally cracked the case. On December 5, 2013, the people's Bank of China, the Ministry of instry and information technology and other five ministries and commissions issued the notice on prevention of bitcoin risk, which first made it clear that bitcoin does not have the status of legal tender, and required financial institutions and Payment institutions not to price procts or services with bitcoin. The central bank believes that there are three risks in bitcoin Trading: high speculative risk; High risk of money laundering and being used by criminals or organizations. In the future, the future of bitcoin is not clear, especially in sovereign countries, which will take a prudent and conservative attitude towards currency, which involves financial order and national security. Therefore, the public should also raise enough risk awareness.

7. Is bitcoin the most anonymous blockchain asset? What is the strongest
the second major feature of blockchain assets is anonymity. That is, no one else can know how many blockchain assets you have and with whom you have transferred money. There are different degrees of anonymity
the anonymity of bitcoin is the most basic. You can only find transfer records on the blockchain network, but you don't know who is behind the address. However, once you know the person behind the address, you can find all the relevant transfer records and assets. The anonymity of dascoin and Monroe coin is higher. Even if you find out who is behind the address, you can't know all the transfer information
and zcash achieves the utmost anonymity, only the person with the private key can find all the transfer information.

8. Little knowledge of blockchain: what are the characteristics of blockchain
nowadays, blockchain has become an area of public concern, and many enterprises have already studied the implementation of this technology. However, there are still a large number of people who are not familiar with the relevant concepts of blockchain technology. Recently, Viking Research Institute and think tank a jointly proced the blockchain instry dictionary. Bianews, as a media partner, has been authorized to popularize the knowledge of blockchain every day
today, bianews will bring you a little knowledge of blockchain. (2) the characteristics of blockchain
1. Anonymity / anonymousness because the data exchange between the nodes of the blockchain follows a fixed and predictable algorithm, the blockchain network does not need to be trusted and can exchange data based on address rather than personal identity
2. Autonomous / autonomous blockchain adopts consensus based mechanism, which enables all nodes in the whole system to exchange data, record data and update data freely and safely in a de trusted environment, without any human intervention
3. The open / openness blockchain system is open, and any node can have the total account book of the whole network. Except that the private information of the parties directly related to the data is encrypted by asymmetric encryption technology, the data of the blockchain is open to all nodes, so the information of the whole system is highly transparent
4. The digital nature of programmable / programmable distributed ledger means that blockchain transactions can be associated with computing logic and are programmable in nature. Therefore, users can set algorithms and rules to automatically trigger transactions between nodes
5. The traceability / Traceability blockchain stores all the historical data after the genesis block through the block data structure, and any data on the blockchain can be traced back to its origin through the chain structure
6. Tamper proof / after the information of tamper proof blockchain is added to the blockchain through consensus, it is jointly recorded by all nodes, and the mutual correlation is ensured through cryptography, so the difficulty and cost of tampering is very high
7. The collective maintenance / collectively maintain blockchain system is jointly maintained by all the nodes with maintenance function. All nodes can query blockchain data and develop related applications through open interfaces
8. No license / permissionless no license means that all nodes can request to add any transaction to the blockchain, but only if all users think it is legal.

9. You're totally wrong about that<

there is no need for an exchange. The exchange is used for currency speculation, not for payment.
there is only a list of collection addresses. You don't know who the payee represented by the address is because there is no server record, so you can't find who received the money
