Bitcoin and cryptocurrency

1.

Differences:

non encrypted currency (enterprise currency):

1, personal behavior

2, company's own currency

3, unable to decentralize

4, unable to trade on international trading platform

5, unlimited issuance

6, no mine website, no original code

7, controllable price, mostly one-way relationship (dining ticket of an enterprise, Qmoney and so on)

open source digital cryptocurrency:

1. Decentralization -- not regulated by indivials, companies and national banks

2. Limited issue

3. Free trade on international trading platform

4. Original code

5. Not taxed, not frozen, uncontrollable price

cryptocurrency advantages:

1. Compared with paper money, Save the cost of printing, data audit, anti-counterfeiting, escort circulation, safe keeping and so on

2. It is impossible to control the number of issues without issuing institutions

3. Borderless. If you use cryptocurrency transaction, directly enter the account address, click the mouse, wait for the network to confirm the transaction, a lot of money will pass

4. Using cryptocurrency in any store can save the cost of tax and capital supervision

5. It is not controlled by the central bank and the quantity is limited, so it can completely resist the pressure of inflation. Let the wealth of the common people keep its value and increase its value The cryptocurrency other than bitcoin is also known as counterfeit currency and competitive currency (English: altcoin). Part of it is a virtual currency similar to bitcoin, which is based on the ideas, principles and source code of bitcoin. At present, more than 800 cryptocurrencies are in circulation

because bitcoin itself does not have an authoritative issuing institution and state power to maintain its authority and uniqueness, bitcoin and its imitators can only get along equally. It is not absolutely exclusive

2. 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.

3. The i7-6700k itself is not locked, and the default frequency is 0.6GHz higher than the i7-6700
moreover, the TDP of the former is much higher than that of the latter, which shows that Intel has left a huge space for overclocking of i7-6700k
therefore, after overclocking the i7-6700k, the i7-6700 will naturally be pressed by force. There is no doubt about this
it should be said that Intel has made the non frequency locking K version more conscientious this time
however, when it is usually used, such a big gap is not felt
if i7-6700k is not overclocking, it is similar to 6700
after overclocking, there is an experience improvement in large software.

4. 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.

PSTN (public switched telephone network)

is a global voice communication circuit switched network, including commercial and government-owned

includes commercial and government-owned. It also refers to simple old fashioned telephone service (POTS). It is a collection of all circuit switched telephone networks since Alexander Graham Bell invented the telephone. Today, in addition to the final connection between the user and the local switchboard, the PSTN has been fully digitized technically

extended data:

the main components of PSTN network are as follows:

1. Transmission system: cable (cable, optical fiber) is the main, cable and wireless (satellite, ground and radio) are used alternately, and the transmission system transits from PDH to SDH and DWDM

2. Switching system: the switching equipment in the telephone office, the exchange, has been programmed and digitized graally, and the connection process is controlled by computer

User system: including telephone, fax and other terminals, and a pair of wires used to connect them with the switch (called user loop). The user terminal has been graally digitized, multimedia and intelligent, and the user loop has been digitized and broadband

Signaling system: in order to realize the communication between users, various control signals are provided between exchange offices, which are mainly call establishment and release

access through PSTN:

dial up Internet / Intranet / LAN- Network interconnection between two or more LANs

Although PSTN has some problems in data transmission, it is still an irreplaceable networking medium (Technology). In particular, the application of xDSL technology and procts invented by Bellcore, which is based on PSTN, expands the development and application space of PSTN, making the networking speed between 9mbps and 52mbps

6. 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.

7. 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
