Encyclopedia of btc123 trading platform

Mt. gox2, the operator of the world's largest bitcoin exchange, announced on 28 February that it had applied to Tokyo District Court for bankruptcy protection because 850000 bitcoins on the trading platform had been stolen

I have always trusted btc123. In 2013, I first found the fxbtc mainland platform on btc123 to buy bitcoin, and fxbtc collapsed and lost a lot of bitcoin. At that time, I thought that the mainland platform was not very reliable. Then I found mycoin on btc123, the Hong Kong platform. Considering that the legal system in Hong Kong is more perfect and btc123 is an endorsement, it should be safer. So I bought 2 million bitcoin from huocoin.com and transferred it to the multi currency treasure in mycoin platform for storage!!! Often login multi currency account, has been able to log in, and every day there is interest payment. In February of 2015, I happened to see the news that the boss of the platform ran the road and Hong Kong's capital took 3 billion yuan away!!! Then the mainland economic investigation called the police and refused to accept it. It said that the office address was in Hong Kong and asked me to call Hong Kong to report to the police. The Hong Kong police station received a call saying that I should report to the police in the mainland, and bitcoin did not accept the call to report to the police. Finally, it said that I could report to the police online first. I called the police on the Internet, no news!!! Now call the day should not, call the ground not work!!!! I hope the media, the government or the police can help me. I can't say that I have no hard-earned money for 15 years! I wonder if we can sue btc123 together? What else can we do to rece the loss? Thank you

4 the transfer in and transfer out of bitcoin refers to the transfer of bitcoin between the trading platform and the bitcoin wallet. The bitcoin wallet needs to be downloaded from the bitcoin official website, and the data needs to be synchronized after downloading and installing, The current packet size is about 8.5g, which takes a long time to synchronize. For friends with small investment, you can skip it. After the installation of bitcoin wallet, there will be a default acceptance address, which can be pasted when the trading platform withdraws bitcoin, while recharging is a reverse operation. The trading platform will give you an address

1. the transaction of bitcoin needs to pay a certain handling fee. The transaction handling fee of bitcoin China is 0.3%, which is equivalent to the upper limit of the Commission of stock transaction. In the trading platform, there is the latest trading data, also can refer to btc123, the market data is more intuitive. Bitcoin trading is different from securities trading.

Development process

Cryptography (in Western European languages, from Greek krypt) ó S "hidden", and gr á Writing is a subject that studies how to transmit information in secret. In modern times, especially the mathematical study of information and its transmission, it is often regarded as a branch of mathematics and computer science, and is also closely related to information theory

Ron Rivest, a famous cryptographer, explained: "cryptography is about how to communicate in the presence of enemies". From the perspective of engineering, this is equivalent to the similarities and differences between cryptography and pure mathematics. Cryptography is the core of information security and other related issues, such as authentication and access control. The primary purpose of cryptography is the meaning of hidden information, not the existence of hidden information

cipher is an important means for communication parties to transform information according to the agreed rules. According to these rules, changing plaintext into ciphertext is called encryption transformation; Changing ciphertext into plaintext is called decryption transformation. In the early stage, cipher only added or decrypted words or numbers. With the development of communication technology, voice, image and data can be added or decrypted

the rule of crypto transformation is called cryptosystem. The parameter indicating this transformation is called the key. They are an important part of cryptography

scrambling-a series of sequences composed of finite elements are used as scrambling numbers, which are combined with plaintext sequences to form ciphertext according to the specified algorithm. The above four cryptosystems can be used alone or in combination to proce practical cryptosystems with high complexity

according to the rules of text and password, under certain conditions, various technical means are adopted to analyze the intercepted ciphertext, so as to obtain the plaintext and restore the cipher system, that is, to decipher the password. The requirements for decoding codes of different strength are different, even very different

in 480 BC, Persia secretly assembled a powerful army to launch a surprise attack on Athens and Sparta

since most people were illiterate in ancient times, the earliest form of secret writing only used paper and pen or equivalent items. With the improvement of literacy rate, real cryptography was needed. The two most classical encryption techniques are:

transposition cipher: rearrange the alphabetic order, such as' help me 'to' ehpl em '

substitution cipher: systematically changing a group of letters into other letters or symbols, such as' fly at once 'to' GMZ Bu podf '(each letter is replaced by the next letter)

research

as the main discipline of information security, cryptography of Xi'an University of electronic science and technology ranks first in China

in 2001, information security specialty was established on the basis of cryptography, which is the first batch of universities in China to set up this specialty

the information security major of Xi'an University of Electronic Science and technology relies on the first-class national key discipline "information and Communication Engineering" (the second in China) and the second-class national key discipline "cryptography" (the first in China), which is the innovation platform of 985 project advantage discipline and the key construction discipline of 211 project

State Key Laboratory of integrated service network theory and key technology, National Engineering Laboratory of wireless network security technology, modern switching and network coding research center (Chinese University of Hong Kong - Xi'an University of Electronic Science and Technology), Key Laboratory of computer network and information security, Ministry of ecation The Key Laboratory of the Ministry of ecation and other national, provincial and ministerial scientific research platforms

among the 34 directors of the Chinese society of cryptography, 12 are from Xidian, and the two vice directors are graates of Xidian. The only member of China in the international society of cryptography is also from Xidian. It is no exaggeration to say that Xidian has become the core base for training cryptography and information security talents in China

the following is a brief list of Xi'an Xin'an graates: Lai Xuejia, member of international cryptographic society, designer of idea block cipher algorithm; Chen Lidong, research fellow of American Bureau of standards; Ding Cunsheng, Professor, Hong Kong University of science and technology; Xing Chaoping, NTU Professor, Singapore; Feng Dengguo, director of the National Laboratory of information security, Chinese Academy of Sciences, and vice president of the Chinese cryptographic society

Zhang Huanguo, executive director of China cryptographic society, Professor of Wuhan University and leader of Xin'an; He Dake, vice president of China cryptographic society, Professor of Southwest Jiaotong University and leader of Xin'an; He Liangsheng, chief cryptographer of PLA General Staff; Ye Jiqing, director of key management center of PLA

Xi'an University of Electronic Science and technology has three Chinese leaders in the field of information security: Xiao Guozhen, Wang Yumin and Wang Xinmei. Among them, Professor Xiao Guozhen is one of the main pioneers of modern cryptography in China. His concept of statistical independence of combinatorial functions and his spectral characterization theorem of correlation immunity of combinatorial functions are internationally known as Xiao Massey theorem

has become one of the basic tools of cryptography research, and opened up a new field of stream cryptography research. He is a member of the Executive Committee of the Asian cryptographic society, vice chairman of the Chinese cryptographic society, and a consultant to the editorial board of the International Journal of information security (ijis)

in 2001, WAPI, the mandatory standard for wireless network security formulated by Xi'an University of Electronic Science and technology, shocked the world. China owns the completely independent intellectual property rights of the technology, breaking the monopoly of IEEE in the world. The Wall Street Journal reported at that time that "China's Encryption Standard for wireless technology caused confusion in the instry."

this technology is also one of the few significant scientific and technological advances that China has made in the IT field with world influence

the information security major of Xi'an University of Electronic Science and technology ranked first in China for many years, which is the best reflection of its leading position in the national information security field

This is a Linux system IP address configuration command. The specific meaning is:

set the IP address of the system to 192.168.0.2; The subnet mask is 24, that is 255.255.255.0; The broadcast address is 192.168.0.255; The name of NIC device is eth0

all computers in the network must set a unique IP address to communicate normally. Because of this unique address, users can select the objects they need from thousands of computers efficiently and conveniently when they operate on networked computers

eth0 is the name set by the system for the network card. If there are al network cards or multiple network cards, there will be names like eth1 and eth2. The name can be set artificially. It is the unique name of the network card in the current computer system
