Virtual currency with high anonymity

2.

Background: the financial application of blockchain technology brings high investment value

2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles

1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:

in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost

2. Why can blockchain solve the above pain points:

blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs

3. The application of blockchain technology in the financial field mainly includes the following aspects:

① digital currency

among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits

Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost

③ digital bills

④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost

The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology

4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points

in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it

Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall)

In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreement

bitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain

based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network

2. Master node network

the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

3. 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.

4. 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.

5. 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.

6. itcoin" Account number & quot; There is no need to associate a name with an indivial. Each balance is simply associated with a randomly generated public / private key pair, and the money belongs to the person who owns the private key and can use it to sign the transaction. These transactions signed with these keys also do not need to contain names. A bitcoin address is a public key, which looks like this: everyone can have many such addresses, and each address has its own balance, which makes it more difficult to determine who owns the money. To protect privacy, Bob can even generate a new public / private key pair for each indivial transaction. In this way, the coin David receives from Charley will not be able to determine who is the second owner in the transaction list (without asking Charley).

7. Hello, most of these platforms are not compliance channels, or even illegal,
but there is no problem, so it can not be determined
few investors and poor liquidity; Lack of supervision and serious manipulation.

8. The reason why blockchain makes money is the application of the project. The application will consume token, which will naturally appreciate.

9. Digital currency and cash, of course, a stronger cash.
