Bitcoin encryption or bitcoin

1. It's very strange that you ask this question. Why does no one care? Atomic currency is given to users free of charge in China through app registration, playing atomic games, advertising and so on. People have said that China and the United States do not sell it. What's the problem with no sale transaction? Moreover, atomic currency issuers are from foreign countries.

2. blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust in the past. This technical solution mainly allows any number of nodes in the participating system to generate a series of data blocks by using cryptographic methods. Each data block contains all the information exchange data of the system in a certain period of time, and generates a data fingerprint to verify the validity of its information and link to the next database block
blockchain technology originates from bitcoin, and its essence is to create a decentralized digital currency system by using computer algorithm and cryptography technology, so as to realize the functions of currency issuance and transaction
characteristics of blockchain Technology:
1. Decentralized: there is no centralized hardware or management organization in the whole network, the rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system. Therefore, it can also be considered that the blockchain system has excellent robustness

2. Trustworthiness: there is no need to trust each other when participating in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are also open. Therefore, in the specified rule range and time range of the system, nodes can not and cannot cheat other nodes
3. Collective maintenance: data blocks in the system are jointly maintained by all nodes with maintenance function in the whole system, and these nodes with maintenance function can be participated by anyone
4. Reliable database: the whole system will enable each participating node to obtain a of the complete database in the form of sub databases. Unless more than 51% of the nodes in the whole system can be controlled at the same time, the modification of the database on a single node is invalid, and the data content on other nodes cannot be affected. Therefore, the more nodes and computing power in the system, the higher the data security in the system
the other two features are derived from the four features:
5. Open source: because the operation rules of the whole system must be open and transparent, the whole system must be open source for the program
6. Anonymity: since there is no need to trust each other between nodes, there is no need to disclose the identity between nodes, and each participating node in the system is anonymous< EGD: e-gold coin, or EGD for short, is a network encrypted digital asset based on peer-to-peer Internet open source protocol, which circulates in a decentralized network system. EGD, as a kind of consumer asset given by global commercial consumers from businesses, is used to replace the points issued by businesses in traditional commercial society, realizing the networking, integration and capitalization of global commercial points
EGD, namely network gold, is an encrypted digital asset based on decentralized digital encryption technology. EGD was born in January 2014. It was developed by a team of 17 technical experts from seven countries around the world, led by former Microsoft engineers. EGD introces the technology of encrypted digital assets into the field of global business integration points, which enables global consumers to continuously share the profits of commercial society through the circulation and value-added of EGD business points, and create a win-win economic model for businesses and consumers
features of customized EGD:
with customized technology, we can easily build all kinds of intelligent assets based on EGD protocol, including stocks, bonds, or various derivative points
more importantly, customization technology not only expands the application scope of EGD, but also retains the characteristics of clear property rights and decentralization of EGD. Moreover, e to the limited number of customized points, customized points are more scarce.

3. My friend, first of all, you can find out what is virtual currency and what is digital currency!

4. According to a new survey released by Walker sands
communications in Chicago, American consumers believe that bitcoin payment is more secure than mobile wallet applications

according to the report, 3% of the 1400 sample consumers think that bitcoin is the safest way to pay, compared with only 1% who think mobile wallet is the safest way to pay< According to the report,

"consumers think that mobile wallet payment applications are unsafe payment methods, even lagging behind the cryptocurrency bitcoin."

among all the payment methods, cash is the most reliable way for these consumers. 56% of the respondents said they like to use cash, while 22% chose credit card and 18% chose debit card

only 2% of the respondents said that they thought check was the most reliable payment method

in addition, the report also found that there is a trend of consumers' payment methods turning to digital payment, which is accelerating with the emergence of mobile payment procts such as apple pay.

5. Bitcoin is the first cryptocurrency, and other cryptocurrencies are collectively referred to as Shanzhai coin. At present, the popular blockchain technology uses the underlying technology of bitcoin

6.

Bitcoin is illegal in China

according to the "notice on preventing bitcoin risks" issued by the people's Bank of China on December 5, 2013:

bitcoin has four main characteristics: no centralized issuers, limited amount, no geographical restrictions and anonymity. Although bitcoin is called "currency", it is not a real currency because it is not issued by the monetary authority and has no legal compensation and mandatory monetary attributes. In nature, bitcoin should be a specific virtual commodity, which does not have the same legal status as currency, and can not and should not be used as currency in the market

at this stage, financial institutions and Payment institutions are not allowed to price procts or services with bitcoin, buy or sell bitcoin as a central counterparties, underwrite insurance business related to bitcoin or include bitcoin into the scope of insurance liability, and directly or indirectly provide customers with other services related to bitcoin, including: providing customers with bitcoin registration Trading, clearing, settlement and other services; Accept bitcoin or use bitcoin as a payment and settlement tool; Carry out bitcoin and RMB and foreign currency exchange services; Carry out bitcoin storage, custody, mortgage and other services; Issuing financial procts related to bitcoin; Take bitcoin as the investment target of trust, fund, etc

extended data:

the risk of bitcoin

1, higher speculative risk. Bitcoin trading market capacity is small, trading 24 hours in a row open, there is no price limit, the price is easy to be controlled by speculators, resulting in dramatic fluctuations, great risk. Ordinary investors blindly follow suit and are easy to suffer heavy losses

2. Higher risk of money laundering. Due to the anonymity and geographical freedom of bitcoin transaction, its capital flow is difficult to monitor, which provides convenience for money laundering and terrorist financing activities

3. The risk of being used by criminals or organizations. As of December 6, 2013, there have been international criminal activities such as drug and gun trading using bitcoin, and relevant cases have been investigated and dealt with

7. Bitcoin system uses asymmetric encryption to improve transaction security. This is what people from Yingfu College of Finance and economics told me. There was a friend there at that time

in the process of information encryption and decryption, different keys are used. Only the corresponding public key can be used for decryption. Owning the private key is equal to owning the ownership of bitcoin

similarly, bitcoin users also need to pass authentication to ensure the ownership of their own cryptocurrency assets.
