Telegram virtual currency
blockchain blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and cryptocurrency algorithm. Is a shared distributed ledger in which transactions are permanently recorded through additional blocks
2, block - block
in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given
In POS mode, your "mining" income is directly proportional to your currency age, and has nothing to do with the computing performance of the computer8. Smart contract
smart contract is a kind of computer protocol which aims to spread, verify or execute the contract in an information way. Smart contracts allow trusted transactions without a third party, which are traceable and irreversible
9, time stamp
time stamp refers to the string or encoding information used to identify the recorded time and date. The international standard is ISO 8601
Turing completion refers to the ability of a machine to perform calculations that any other programmable computer can perform DAPP decentralized application is an open source application that runs automatically, stores its data on the blockchain, motivates it in the form of cryptocurrency token, and operates with protocols showing valuable proof Dao, a decentralized autonomous organization, can be regarded as a company that operates without any human intervention and gives all forms of control to a set of unbreakable business rules13. Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address
14. Publickey -- public key
is paired with private key. The public key can calculate the address of the currency, so it can be used as a certificate to own the address of the currency
15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining
18. Private chain
write permission is only for the blockchain of a certain organization or a specific few objects. Read permission can be open to the outside world or restricted to any extent
19, alliance chain
consensus mechanism is a blockchain jointly controlled by several designated institutions
20, side chain
wedged side chains technology, which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which means that users can access the new cryptocurrency system when they use their existing assets
21, cross chain technology
cross chain technology can be understood as a bridge connecting the blockchains, and its main application is to realize atom transaction, asset conversion, information exchange within the blockchain, or solve Oracle problems among the blockchains
22. The hard fork
blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value
generally translated as "hash", but also directly transliterated as "hash". In short, it is a function that compresses messages of any length to a message digest of a fixed length
25, main chain
the word "main chain" comes from the main network (, relative to the test network), that is, the officially online and independent blockchain network
for those who don't know the "jargon" in the currency circle, let's learn it as soon as possible:
1. What is legal currency legal currency is legal tender, which is issued by the state and the government. It is only guaranteed by the government credit, such as RMB, US dollar and so on 2. What is a token token, usually translated into token. Token is one of the important concepts in blockchain. Its more well-known name is "token". However, in the view of professional "chain circle" people, its more accurate translation is "token", which represents a proof of rights and interests on the blockchain, rather than currency token one is digital proof of rights and interests, which must be in the form of digital certificate of rights and interests, representing a right, an inherent and intrinsic value
3. What is warehouse building
the establishment of a position in a currency circle is also called opening a position, which refers to a trader's new purchase or sale of a certain amount of digital currency
What is Sohasuoha refers to investing all the principal
What is airdrop
airdrop is a very popular marketing method of cryptocurrency. In order to let potential investors and cryptocurrency enthusiasts get token related information, token teams often air drop tokens
6. What is lockup position locking generally refers to investors opening a new position opposite to their original position when the market moves in the opposite direction after the sale and purchase contract, which is also called lock, lock order, or even butterfly double flying doughnut candy is a kind of free digital currency issued to users when all kinds of digital currencies are just issued in ICO. It is a kind of momentum and publicity of the project itself by the issuers of virtual currency projects
breaking refers to falling below, and issuing refers to the issuing price of digital currency. Broken currency circle refers to the price of a digital currency falling below the issue price
What is private placementprivate placement is a way to invest in cryptocurrency projects, and it is also the best way for cryptocurrency project founders to raise funds for platform operation
What do you think of the K-line diagram
K-line chart is also called candle chart, Japanese line, yin-yang line, bar line, red and black line, etc., commonly referred to as "K-line". It is based on the opening price, the highest price, the lowest price and the closing price of each analysis cycle
What is hedging
General hedging refers to two transactions which are related to the market, opposite in direction, equal in quantity and balanced in profit and loss. In the futures contract market, buy the same number of positions with different directions. When the direction is determined, close out the positions in the opposite direction and keep the positive direction to make profits

Gram is a general token issued by telegram based on ton blockchain system
related introction:
based on the basis of telegram, the end-to-end encryption in gram ensures that the message can only be read by the receiver. Through secret chat, our server does not store any content, you can freely write and destroy messages on two devices. The team named the official gram community as gramspace, which has the nature of sandbox and unlimited expansion
users can buy land, grow crops, build buildings and so on in gramspace. Finally, as an enhanced design of telegram, gram provides rich interfaces, which can be compatible with AR devices and 3D printing devices
extended data
the fuel token of gram system is also called gram. Users can use gram to enjoy a variety of value-added services in the telegraph space, improve the mining efficiency, and directly purchase other users' houses or plots to expand their telegraph space
gram sugars can be used to exchange gram, the token of the same name of gram platform. Gram can be used for various activities of telegraph planet, and can also be traded through the exchange
tokens usually need to be exchanged for money, used in shops, playgrounds, mass transit and other places, as a certificate to use services and exchange goods. The token is mainly made of metal or plastic
the mines in craftsman Street are not very good, most of them are low-grade mines, There are no veins you want to mine.
in addition, you can find veins in the map of hunting monsters. Generally, there are 2-4 veins in one map, and the minerals in each map are fixed. If you dig out one, you will regenerate another one in a few minutes.
generally, what kind of veins can be mined can be judged by the color. Agile mother mine will mine green veins, The red vein is mined in the power mother mine, the black vein is mined in the dark crystal mother mine, and the purple vein is mined in the lucky mother mine and the wisdom mother mine. These mining grades are from low to high according to the order I wrote. If the mining grade is low, it's easy to fail. If you mine more low-grade mines, you can accumulate proficiency. Go to the craftsman street to teach you how to upgrade (for a little money), and the mining grade will soon go up, Then go to mine the mine you want
mining will increase the fatigue, a total of 200 points, mining will increase by 1 point, every hour will recover a little, 0:00 in the morning will return to 0, pay attention to the fatigue is full, can't mining yo

Quantify the similarity between cryptocurrencies
data collection
cryptocurrencies have a large number of indicators, such as daily trading volume, daily volatility, number of twitter fans, etc. In this study, we will focus on social media and community development indicators. We will collect relevant data on the attention and interaction of major social media, including twitter, telegram, etc. At the same time, we will also track the number of development community activities, such as fork, star, issue, etc. In total, we collected about 20 different indicators
definition of similarity
because the indexes of cryptocurrency we are concerned about are different types (the mixture of discrete and numerical data with different distributions) and of different importance, we can not simply use some conventional distance measurements (such as Euclidean distance) used in linear space to derive the similarity. Simple ranging may distort the true relative importance of these features
Therefore, we use random forest embedding method. This method can effectively map the original heterogeneous data to a very high-dimensional sparse representation. If two data points are very similar in the original feature space, they tend to be classified into the same leaf nodes in each random tree, so that their sparse binary vectors have very short Hamming distance. Therefore, we can simply calculate the inner proct between two sparse vectors in the high-dimensional space transformed into homogeneous features, and take it as a measure of similaritycreate similarity matrix
in this example, we collect data from more than n = 4200 different cryptocurrencies and expand the 20-d space to 11000-d space. As shown in the figure below, this n × N-similarity matrix defines a high-dimensional graph. The stronger the similarity between two currencies, the thicker the edges between them. To reveal the structure of the graph, we embed the 4200-d graph into the 2-D space to analyze and visualize the relationship between all currencies. Therefore, we can further analyze which currencies are closer to high-quality currencies such as bitcoin
through people in the instry logging in to telegram and dark net, the reporter of economic information daily saw that hundreds of millions of personal accurate information of various categories came into view and were being sold to the public. Including personal track information, credit information, property information, accommodation information, communication records, and even facial living information, as long as you click to pay, you can easily get it. The amount of information and transaction volume is shocking "Economic Information Daily" reporter in-depth investigation found that the ubiquitous identity binding, excessive claims increased the risk of personal information disclosure through app and other channels. What is more noteworthy is that under the virtual currency blessing, uncontrollable social platforms such as dark web forums and telegrams are becoming the main channels of information trafficking. How to avoid our information leakage
to tell you the truth, it's basically impossible not to be disclosed. Now you go to the Internet bar, go to the hotel, or register on some unknown apps, then your personal information has been taken to the Internet to sell. But these are all worthless things. What are they worth? Face recognition information, bank card number, some of the whereabouts of life (not commonly used in China), telephone numbers, etc. can be sold at a good price. So if you don't want to disclose these information, you should not give them easily when you encounter them on the Internet street
