Source code query of digital currency

1. In recent years, blockchain digital assets represented by bitcoin have become popular all over the world. Financial institutions, technology companies, investment companies and other participants at home and abroad have invested a lot of human, material and technical resources in the research, development, design, testing and promotion of blockchain digital assets. In order to realize the main characteristics of "four can and three can't" of blockchain digital assets, we can build the core technology system of digital assets by relying on 11 technologies of security technology, transaction technology and trusted guarantee technology. First of all, security technology is used to ensure the fluidity, storability, controllable anonymity, unforgeability, non repeatable transaction and non repudiation of blockchain digital assets. digital currency security technology mainly includes basic security technology, data security technology and transaction security technology. Basic security technology includes encryption and decryption technology and security chip technology. Encryption and decryption technology is mainly used in currency generation, secret transmission, identity verification and other aspects of digital assets. The establishment of a perfect encryption and decryption algorithm system is the core and foundation of the digital assets system, which needs to be customized and designed by the national password management organization. Security chip technology is mainly divided into terminal security mole technology and smart card chip technology. Digital assets can be traded in the form of mobile terminal based on terminal security mole. As the carrier of secure storage and encryption and decryption operation, terminal security mole can provide effective basic security protection for digital assets. Digital asset system trading platform blockchain technology research and development of data security technology, including data security transmission technology and secure storage technology. Data security transmission technology transmits digital asset information through ciphertext + MAC / ciphertext + hash to ensure the confidentiality, security and non tamperability of data information; Data security storage technology stores digital currency information by means of encryption storage, access control, security monitoring, etc., to ensure the integrity, confidentiality and controllability of data information
transaction security technology includes anonymous technology, identity authentication technology, anti plicate transaction technology and anti-counterfeiting technology. Anonymity technology realizes controllable anonymity of digital assets through blind signature (including blind parameter signature, weak blind signature, strong blind signature, etc.) and zero knowledge proof; The identity authentication technology verifies the user's identity through the authentication center to ensure the validity of the digital asset trader's identity; The anti plicate transaction technology ensures that digital assets are not reused by means of digital signature, serial number and time stamp; Anti counterfeiting technology ensures the authenticity of digital assets and transactions by means of encryption and decryption, digital signature and identity authentication. Secondly, the online transaction and offline transaction of digital assets are realized by transaction technology. Digital asset trading technology mainly includes online trading technology and offline trading technology. As a legal currency, digital assets should not be rejected by any unit or indivial, and can be traded online or offline. Online transaction technology realizes online transaction of digital assets through online device interaction technology, online data transmission technology and online transaction processing; The off-line transaction technology realizes the off-line transaction of digital assets through the off-line device interaction technology, off-line data transmission technology and off-line transaction processing technology. Finally, trusted guarantee technology is used to provide a safe and reliable application environment for the issuance, circulation and transaction of digital assets in blockchain. Digital asset trustworthiness assurance technology mainly refers to trusted service management technology. Based on trusted service management platform (TSM), it ensures the security and trustworthiness of digital asset security mole and application data, and provides security chip (SE) and application life cycle management function for digital asset participants. Trusted service management technology can provide application registration, application download, security authentication, authentication management, security evaluation, trusted loading and other services for digital assets, which can effectively ensure the security and credibility of digital assets system
what is blockchain? Blockchain technology, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records. Blockchain technology development blockchain technology development what is a blockchain system? Blockchain system is a database system with integrity. The data written into the system will be automatically copied to the nodes of the blockchain, which can achieve transactional data preservation, support the management and development of databases in various instries, and be proced in combination with various needs. 294.497 billion US dollars, or 2.60%. This week, five new projects entered the top 100, namely FST, ZB, Wix, wax and MXM. On August 11, the price of bitcoin was $11523.58, up 3.20% from last week, and Ethereum was $216.09, down 3.86% from last week. The 24-hour turnover of this week increased by 2.63% over the same period last week; Among the top 100 projects, the total market value and average market value of currency projects increased significantly, and the classification composition of global blockchain assets top 100 projects was stable.

2. The emergence of digital currency was born under the expectation of pursuing a more perfect social and economic transaction mode and Global trade facilitation. It was discovered in the process of using science and technology to graally explore this need. The history of digital currency should start with the creation of bitcoin
the creation of digital currency
the origin of digital currency can be traced back to the 1990s, and electronic gold is one of the best forms. E-gold came out in 1999. It is based on real precious metals. Another consistent digital currency service is LR. Founded in 2006, it is an online payment company in Central America. It allows users to convert U.S. dollars or euros into LR, and only 1% of the transaction cost can be exchanged freely. This kind of two-way service is used by some people to launder money, so it is inevitably shut down by the U.S. government under the charge of money laundering
then, a person named Nakamoto published an article called "bitcoin: a peer-to-peer e-cash system" in the cryptography forum, which gave birth to bitcoin. Compared with legal currency, bitcoin does not have a centralized discoverer, but is generated by the calculation of network nodes, and is composed of a series of complex codes generated by computers. Anyone can dig, buy and sell bitcoin, and it is an anonymous transaction and cannot be tampered with. As a result, it is surrounded by geeks of popular technology, pursuers of complete liberalism and speculators
digital currency can be divided into open mining cryptocurrency and issuing cryptocurrency. Digital currency is defined as an Internet-based currency or exchange medium, which is different from physical currency. Digital currency can realize instantaneous transaction and ownership transfer without borders
for reference.

3. You said that is the encryption digital currency, the source code son in the open source website may inquire. You can also go to the official website of bitcoin foundation to find the source code of bitcoin
network virtual currency can be roughly divided into
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. Mainly used for Internet financial investment, can also be used as a new currency directly for life

4. Digital currency source code open source does not mean that this kind of digital currency must be safe, but the purpose of source code open source is to be open and transparent, to prevent pre excavation, which is also a necessary condition for a digital currency
there is not much relationship between the open source of digital currency and the security of digital currency. The security of digital currency is determined by many factors. Bitcoin is the most well-known digital currency at present, but its security has always been a very big problem, while Ruitai coin and vitality coin are relatively low in popularity, but there are few problems.

5. Now the country has just started, many things of digital currency are not so formal, and we should wait for a period of time

6. Searching the keyword "hitcoin" on the Internet can not find any relevant information, let alone relevant news reports. As for where to inquire, there is no way to answer this question. Whether it is a real digital currency is still uncertain, and whether the source code has been made public is also uncertain
for this kind of digital currency, we should be careful to invest. It is better not to invest in the digital currency that we don't know. If we want to invest in some digital currencies, we suggest to invest in the market tested digital currencies such as bitratte and Leyte.

7. You're right about little monsters, but boss is different.
CQ No.1 cuts small ones first, if FS can be controlled, it can be controlled. If DZ is not controlled well, it needs to interrupt the treatment of little monsters.
boss No.2 has a skill & quot; Rebellion & quot; Many melee players don't notice and kill their teammates or even MT by mistake. No.2 will call helldogs, which burn blue very badly. However, DZ doesn't care, but usually give SS or MT to hold No.3, and pay attention to the fire on the ground, and don't stand in front of the boss to output

Pt No.1 has nothing to pay attention to
No.2 DZ wants to play the ball released by boss, Play 4 instant cloaks in a row
No.3 is similar to PVP t good MS monster's treatment until the blind throw is good
No.4 interrupts boss's fireball skill, avoids the infernal flame, and works hard after the Phoenix turns into an egg. In the second stage, everyone flies. Let's give 3 purple electric balls DPS to the remote player

MLM in criminal law is different from direct selling. MLM in criminal law is a kind of criminal behavior, and the starting point of criminal behavior is low, which can more severely crack down on criminal behavior and prevent the occurrence of criminal behavior. And legal direct marketing is not MLM, so it will not be punished

Further information:

MLM originated in the United States in the late stage of World War II, took shape in Japan after World War II, and developed in China

In foreign countries, MLM and direct marketing have the same meaning, that is to say, there is only the concept of MLM in foreign countries. The main concept of foreign MLM is to use the word-of-mouth generated by customers' use of procts as the driving force, and let customers help dealers to promote procts and share part of the profits, that is, customer communication sales. This is different from the domestic concept of MLM

however, in China's criminal law, pyramid selling (Chinese style pyramid selling) is a false company, a fictitious proct, and everything is empty. It just lets you pull your head and draw a small commission from the membership fee or franchise fee

The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form.
