Imtoken decentralized exchange

1. 1. I've seen and used the first imtoken. Every year, imtoken loses money, and every time it says that it is a decentralized wallet. It sounds like a shirking of responsibility and decisively unloading
2. I haven't heard of the second one. I guess it's a small wallet from somewhere. I might run away one day
3. Some exchanges provide channels for exchange. You call customer service, customer service will teach you. You can try ZB

3. Find the process, then find his file path, kill the process, delete the file
in addition, find other suspicious processes to avoid viruses having daemons or other hidden processes

4. The following three points are briefly analyzed:
(1) blockchain
since 2013, virtual currency has graally attracted people's attention, and even set off a wave of upsurge of virtual currency. However, many people do not know that the real value is the background technology of virtual currency - blockchain. Virtual currency is only one of the most original applications of blockchain technology, and its rise has brought about a lot of problems, There is also an inevitable reason, that is, blockchain technology endows them with the core characteristics of fairness, impartiality and openness. The practical application of virtual currency is very few, and there is no real value support. Even some virtual currencies recognized by many countries are occasionally traded, not to mention applied. Most of them are just doing price speculation, leading to the price of virtual currency fluctuating, Extremely unstable, because of its price instability, it can not become a real currency. It is precisely because blockchain has the technology gene of fairness, impartiality and openness that almost all banks and financial institutions around the world are studying and using blockchain technology, including UBS, Citigroup, the Federal Reserve, the Bank of England, the Central Bank of China and so on. Why is blockchain so popular? Because it fundamentally enhances the banking instry, supply chain, property management and other trading networks, It is considered to be the core technology with the most potential to trigger the fifth round of disruptive revolution after steam engine, power information and Internet technology 2) (2) smart contract
these advanced applications of blockchain are called "smart contract". Smart contract is the core application that can really bring revolutionary progress. You will find that smart contract is becoming the mainstream of the market, and we will soon enter the era of smart contract
(3) quantum technology
in such a developed world of Internet, how to ensure your information privacy, how to ensure the security of your online banking password, chat records, virtual currency and everything that needs a password, all these are e to the public key and private key encryption algorithm widely used in the current Internet. If this algorithm is decrypted by the current computer, It's almost impossible to complete the task, and it often takes tens of thousands of years or even longer to decrypt. However, within 5-10 years, quantum computers will appear. When quantum computers are used to decrypt, these passwords will only take a few seconds to be decrypted. Our bank funds, social information, and virtual currency will not be safe. Therefore, we can't use quantum computers to decrypt, At present, the research against quantum decryption has become a global hot spot, including the pqcrypto and safecrypto research program supported by the European Union, the crest crypto math research program of Japan, and so on. Major enterprises have also expressed their views, such as Intel's quantum chip, Google's quantum encryption, and quantum communication technologies actively encouraged by governments, So quantum technology is the best future technology. It is not only a spear, but also a shield. It can subvert our current security system and bring us super efficient computing solutions.

XTT (Xin time token), based on Ethereum erc20 platform, is a decentralized digital currency carrier based on blockchain as payment technology

Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014

extended data:

background

bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years

the blockchain of bitcoin is actually a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network

however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions

In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoin

For example, the latest plustoken, the previous wave point wallet, wotoken and sumtoken, etc., great Xia, let's talk about them briefly

this kind of wallet generally claims that the user saves the token in the wallet, and the user cannot master the private key of the wallet. These wallets can be regarded as centralized wallets, which are not the same kind of things as imtoken and other decentralized wallets. Among these wallets, the administrator said that he would take the user's toekn and get the revenue by quantifying the bricks, and then return the revenue to the user in the form of platform token or original token, which is also divided into static, dynamic and so on. Take plus as an example, the monthly static revenue is 10%, which is returned to the users in the form of platform token. With the help of pulling the head, it is claimed that the revenue can reach 100%, and plus has launched a platform called psex, but is there really such a good thing

UB exchange is originally a non mainstream internal exchange, and the so-called universal wallet is also a scam with in but not out

these scams are dressed in the vest of blockchain technology, and they do whatever they want in the market, making huge profits by taking advantage of leek's ignorance and greed, anger and infatuation, and ultimately the injured ones are leek. Finally, I want to explain to you that many wallets with high profits are basically scams. With the development of the market, the price difference between major trading platforms is very small, and there is no profit at all from moving bricks. However, quantification is just some well written trading strategies and proceres, and the profit is really there, But it's not as high as you think. All wallets under the guise of high income are almost naked scams. Bear market is not good, do not because of these so-called high-yield temptation to easily deceive

First of all, remember whether the mnemonic words are at risk of loss. If it is possible to be known by others, please create a new token wallet at the first time and transfer the original wallet assets

if the wallet account in the cornerstone stage cannot be transferred, please contact the project party in time and ask the other party to assist in the transfer of token assets. If you are sure that it belongs to your own deletion or damage and is not known by others, you can choose to note the private key and log in with the private key

mnemonics is another form of plaintext private key, which was first proposed by bip39 proposal. Its purpose is to help users remember complex private key (64 bit hash value)

mnemonic words are generally composed of 12, 15, 18, 21 words, which are all taken from a fixed vocabulary, and their generation order is also based on a certain algorithm, so users don't have to worry about randomly entering 12 words to generate an address

although both mnemonic words and keysore can be used as another form of private key, different from keysore, mnemonic words are unencrypted private keys. Anyone who gets your mnemonic words can easily take control of your assets

So after users backup mnemonics, they must pay attention to three points:

1. Try to use physical media backup as much as possible, such as writing on paper with pen, and try not to take screen shots or photos and put them in networked devices to prevent being stolen by hackers

If one or two words are copied wrong, it will bring great difficulties to retrieve the correct mnemonics

3. Keep the backup mnemonics properly and take anti-theft measures

users can use the backup mnemonics to re import imtoken and generate a new keysore with a new password to modify the wallet password

extended data:

the essence of using imtoken to create wallets is to generate a set of mnemonics randomly. Due to the characteristics of decentralization, imtoken does not keep the privacy information of users' wallets. So after generating mnemonics, users must keep them by themselves. This group of mnemonics can dece the private key, the public key and the address of the wallet

according to the above instructions, if we want to find the mnemonic words, we need to know the generation process of mnemonic words: first, we make a 128 bit random number, and then we check the random number by 4 bits to get a 132 bit number, and then we divide it by 11 bits, so that we have 12 binary numbers, and then we use each number to look up the word list defined by bip39, So you get 12 mnemonics

calculate the number of mnemonics that can be generated, bip39 mnemonics thesaurus contains a total of 2048 words, 12 words in each group. For example, by analogy, the amount of sand on earth is about 1, followed by 18 zeros. If we can generate one million mnemonics per second, we can generate 3.1536 e + 13 mnemonics per year, which takes about 1.6715937e + 26 years to traverse all mnemonics. Therefore, brute force cracking is impossible

if all mnemonics and private keys are lost, they can't be recovered by brute force cracking, because imtoken's decentralization can't be recovered from us. However, if the mnemonic words are lost and the private key is still kept, the use of the wallet will not be affected
