Jingtong virtual currency

1.

blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

2. Blockchain world is proced by Jingtong technology< Make complaints about br / > block chain

3. At present, investment in digital currency at least needs the following points:
1: do a good long-term investment plan, the best way to dig is to dig by yourself, and the best way to dig is to buy or move bricks to make money
2: if the coin is empty, choose the one with less total amount (less amount and more appreciation space), and even large enterprises will not cut the coin with less amount (because the more the coin is cut, the less it is cut)
3: if you can dig and pre dig a little, even a big company can't do something that can dig. If you can dig, you'll get nothing Pre digging is used to cut leeks, so the currency with very little pre digging should be selected.)
Four: choose decentralized wallets instead of smart contracts. More than half a year of operation (so as to ensure the stability of the wallet)
Five: check the code, operation mode and service quality of the trading platform, and choose the one with good reputation, so as to prevent the platform from being stolen and running away. At present, there are few such platforms in China, and it takes time to understand them
six: don't look at landing scenes and publicity, because only empty coins need landing scenes to attract players to buy currency appreciation (depending on the amount).

The law of blockchain is not perfect, and whether Guiren chain is legal and deceptive remains to be verified. You can ask the people's police of the public security organ for assistance in identification or verification. The investigation conclusion of public security organs is the most authoritative. The national unified report telephone number is 110

it is worth noting that Guizhou Guiren big data blockchain Instry Development Co., Ltd. was listed in the list of abnormal operations by the instry and Commerce Bureau on February 28 this year because it was unable to contact through the registered place of business

at present, the state has banned the issuance of crypto digital currency, so it is impossible for any government background digital currency to exist. The right to issue currency is firmly in the hands of the central bank. This company is at most a second-class liquor dealer, and it may not necessarily sell real liquor. We can't judge the authenticity of liquor. What we can judge is that the noble currency is worthless, There is no so-called national background, and there is no Maotai distillery's participation, so don't buy wine because of this kind of virtual currency

extended information:

under the banner of "financial innovation" and "blockchain", some lawless elements absorb funds by issuing so-called "virtual currency", "virtual assets" and "digital assets", thus infringing the legitimate rights and interests of the public

in this regard, the State Administration of market supervision, together with many ministries and commissions, jointly issued the risk warning on preventing illegal fund-raising in the name of "virtual currency" and "blockchain"

according to the analysis of tips, such activities are not really based on the blockchain technology, but the fact of hyping the blockchain concept line to illegally raise funds, pyramid schemes and defraud, which mainly have the following characteristics:

first, the obvious networking and cross-border. Relying on the Internet and chat tools for transactions, and using online payment tools to balance funds, the risks spread widely and spread quickly. Some indivials claim in the chat tool group that they have obtained the investment quota of overseas high-quality blockchain projects and can invest on their behalf, which is most likely fraud. Most of these illegal funds flow overseas, which makes it very difficult to supervise and trace

Second, deception, temptation and concealment are strong. They use hot concepts to hype, fabricate various "tall and tall" theories, and some also use celebrity "big V" platforms to publicize. They use airdrop "candy" as temptation to claim that "currency value only rises but not falls", "investment cycle is short, income is high, and risk is low", which has strong bewitching

Thirdly, there are many kinds of illegal risks. Through public publicity, criminals use "static income" (currency appreciation profit) and "dynamic income" (development offline profit) as t to attract public investment, lure investors and development personnel to join, and constantly expand the fund pool, which is characterized by illegal fund-raising, pyramid selling, fraud and other illegal behaviors

5. Zhao CHANGPENG, the founder of coin an, soon became the largest virtual currency transaction in the world. At the beginning of this year, there were 10 billion US dollars of transaction volume every day. This is really powerful!
