Whether in the past or at present, there are many people who have made great efforts to change the old order of reality.
The story of "One Thousand and One Nights" in history
It is said that in ancient times, on the ancient Arab islands, there was a kingdom of Sassan, and the king's name was Shahryar. One day, Shahryar and his younger brother Saman came to a grassland next to the sea. A girl came to them and told them that all women in the world are faithless and untrustworthy.
After King Shahryar and his younger brother Saman returned to the Kingdom of Sassan, they found that the queen misbehaved occasionally and they killed the queen. Since then, Shahryar deeply hated women and killed the palace girls. He revenged and began to marry a woman for one night every day, and the next day he killed and married again, completely becoming a tyrant. Year after year, it lasted for three years, killing more than a thousand women.
Scheherazade, the eldest daughter of the prime minister, told her father that she would marry the king, and she would try to save thousands of women. After Scheherazade entered the palace, he told the king a story every night, but she only told the beginning and the middle, not include the end. In order to listen to the end of the story, the king delayed the date of killing Scheherazade day after day.
In this way, Scheherazade told a story every day, and her story was endless, one is more exciting than one, and it has been said to one thousand and one nights, and finally moved the king. Shahryar said: "I swear by the name of Allah, I am determined not to kill you, your story moved me. I will record these stories and keep them forever." So, there was the book of "One Thousand and One Nights" ".
Both Arabs and Jews originate from the ancient Semites. In addition to the characteristics of wit and benevolence of the heroine in the article, the Arabs and Jews also have the adventurous spirit of exploring the world and changing the world.
With the development and inheritance of generations, this spirit are still continuing to the present.
Jewish merchant Ajm creates new one thousand and one stories that changing the world
In the winter of 2018, the trust of digital asset investors was consumed. Practitioners involved in blockchain were either dismissed in advance or got through the Spring Festival in fear. The blockchain and digital assets that have been around for 9 years were born in the global financial crisis 10 years ago, and it will undergo a baptism of this harsh economic cycle.
In this year, the three o 'clock community was no longer hot, and the media, investors and project parties began to practise austerity. With the continued decline in digital assets, the industry as a whole are in a downturn.
The blockchain market began to return to calm from the initial fanaticism, and people began to think about the connotation and significance of the blockchain itself. For what the blockchain is, people began to wake up from the original confusion.
The essential significance of blockchain technology is not only in issuing currency, but in reconstructing and shaping the original operation system of traditional industry, thus constructing a new contract system which is more intelligent and safer. How to maximize the value of the blockchain is the problem that everyone in the market should think about.
The old order should be broken, and the new rules of the world need to be established-the Jewish merchant ajm is determined to be the first to change the old world of token assets. The Jewish merchant Ajm is created by Jewish saint JT based on the advanced blockchain 4.0 technology. It is the twin brother of Bitcoin. It is constantly upgraded on the basis of Bitcoin and has the power to change the world, known as digital gold for the 21st century.
The Jewish merchant Ajm's vision for development is to seamlessly connect with billions of people around the world and create a decentralized application ecosystem that will transform the world.
After ten years of dormancy and accumulation, the Jewish merchant Ajm finally ushered in the opportunity to make a magnificent appearance: to change the traditional world, the large ship of Jewish merchant Ajm to innovate the global digital economy has set sail!

Tark Wallet invites you to win the 5G era together
2019 is the first year of 5G in the world, and it is also the first year of blockchain development. Many countries hope to successfully get the first batch of "ship tickets" for 5G commercial use through blockchain technology.
GSMA expects that by the end of this year, 29 markets around the world will open 5G services and the number of connections will reach 10 million.
According to the research report of IHS, by 2035, 5G will generate 12.3 trillion US dollars of economic output globally. This is almost equivalent to the total expenditure of all US consumers in 2016, and exceeds the total consumption expenditure of China, Japan, Germany, the United Kingdom and France in 2016. By 2035, the global 5G value chain will create $3.5 trillion in output while creating 22 million jobs. The above figures exceed the value of the entire mobile value chain today.
Faced with such a huge technological dividend, whether or not we can grasp the commanding heights of technology has become the focus of competition.
It may be difficult for a technology to support a scenario, but when combined with multiple technologies, there will be many prospects for emerging scenarios. In the fierce competition, Tark conforms to the trend to create a blockchain +5G landing application scenario to seize market opportunities. "The blockchain 4.0 innovated by Tark Wallet is an important underlying technology in the era of digital economy. The combination of 5G may release huge economic value and the prospects are limitless," said the head of the tark project.
The function and performance advantages of 5G can further promote the development of the blockchain. In a general centralized trading system, the privacy protection is provided by the trusted center. Tark Wallet is a truly decentralized product based on Blockchain 4.0 technology. The 5G network can increase the number of participation of the Tark blockchain nodes, further improve the decentralization of the blockchain, reduce the block generation time of the blockchain, directly promote the blockchain, and promote the scalability of the blockchain. To provide better support for users of tark wallets, so as to create a new global cross-border settlement and achieve the ultimate goal of digital bank.
The great advantage of 5G is its high speed, high power capacity, low latency and the ability to connect a large number of devices. On this basis, the security, decentralization, can not be untampered and consensus mechanisms of Tark blockchain wallet technology are used as the base layer to further improve its performance through its low latency, high speed and high capacity, covering capabilities, changing the bottleneck of the development of the Internet of Things.
We believe that with the help of 5G network and blockchain technology, smart cities, driverless cars, smart homes and other sensor-driven enhancement technologies will eventually meet the needs of people's work and life in the future, human consensus and freedom will rise to a new level.
Tark - the outstanding representative of the decentralized cryptographic asset wallet
In recent years, with the rise of the blockchain industry, the development of wallets has been driven, but as the most critical infrastructure of cryptographic asset wallets, security has never been fundamentally solved.
On May 8, 2019, the official announcement of Binance said that on September 7, 2019, 17:15:24 (UTC) "large-scale security vulnerabilities" were discovered in the system. The hacker used a composite technology to exploit the vulnerability to steal 7,000 bitcoins from the Binance wallet at block height 575012. This theft incident has deepened the trust crisis in the entire blockchain industry.
What kind of wallet is really safe?
Cryptographic asset wallets are essentially tools for storing private keys. The security of private keys is critical. To maximize security, Tark's technical team builds Tark wallets based on Blockchain 4.0 technology. Unlike the past blockchains 1.0, 2.0, and 3.0, Tark Wallet has made a qualitative leap in terms of security performance, transaction speed, consensus extreme, cross-chain transmission, and ecological applications. The private key of the Tark wallet is owned by the user. The assets are stored in the blockchain,is isolatedly stored locally, the private information will never touch the network, and the wallet private key is kept by the user. The assets are completely in their hands. Don't worry about the centralized attack by hackers, or worry about the inside job of the wallet service provider.
Two super features of Tark wallet
2, Anonymity: In the general centralized trading system, the center of trust provides privacy protection. All user information and transaction information are stored in the central database, and ordinary people cannot easily obtain the customer's information. Only the trust center holds the information of everyone. Based on blockchain 4.0 technology, Tark's wallet is a truly decentralized product whose nature determines that no one can easily access the user's information.
Six advantages of Tark wallet:
2, Second speed: Tark is based on blockchain 4.0 atomic cross-exchange technology and cross-chain lightning trading, the atomic exchange is carried out on the lightning channel, and the infinite high-speed transaction between any block chains is realized to realize the nearly infinite transaction speed.
3, Multi-account system: Blockchain 4.0 technology gives users the right to truly master their digital assets and personal data, with the help of cryptographic public and private key wallet accounts, to become the user's unique digital identity. Tark Wallet creates multiple accounts with one identity, eliminating the need for multiple tools to manage multiple private keys for users, and one identity can manage different passport assets.
4, Offline signature: avoid private key networking, reduce the risk of theft. Each transaction involves the issue of signature confirmation. The Tark wallet user holds the private key, and the transaction is not connected to the private key. The transaction is more secure.
5, Multiple verifications: fingerprint, face recognition and other verification methods.
Tark wallet is a typical application example of blockchain 4.0 technology, and is also an outstanding representative of decentralized cryptographic asset wallet. In the future, we hope that Tark can help more cryptographic asset enthusiasts, businesses and enterprises solve their security crisis and make billions of people around the world really feel the convenience of the Tark wallet.
Tark Wallet: How important is the private key?
The private key determines the ownership of the blockchain asset, and the loss of the private key is equivalent to the loss of everything.
When it comes to digital wallets, security is a topic that can never be bypassed.
Safety is in, money is in!
Poor security, money is risky!
No safety, no money!
Today, we will analyze how to ensure security from the perspective of the private key, a corner of the digital wallet security field.
First, the private key needs to be sufficiently random. The private key is actually a random number, but the concept space of this random number is relatively large - 256th power of 2. The private key is typically generated randomly by the wallet. What we want to emphasize is that the generation process of the random number of the wallet must be really random, which is very important.
Computer-generated random numbers are generally called pseudo-random because they have a deterministic algorithm that works with a seed (such as time) to produce some seemingly random results, but in reality anyone can master the algorithm and master the seed. It is possible to get the same result, which means that it is predictable. For example, bitcoin, there are 256 powers of 2 small drawers in the universe, generating a bitcoin private key, which is to randomly select a drawer to put money in.
Because this number is large enough, all the people on the planet generate a private key every second and will not repeat, so this mechanism is relatively safe. At the end of 2014, there was a serious random number problem in a version upgrade in Bitcoin wallet blockchain.info, the loss of coins was caused by the repeated R value. It was quickly discovered by a white hat hacker and the problem was fixed two and a half hours later. However, during this 2.5 hours, more than 200 bitcoins with more than one thousand addresses were lost, so the random number is a "lifeblood" in the blockchain.
Second, the private key is not connected to the Internet. Because now hackers are almost pervasive. Not mention that our civilian systems and construction, just like the US military's very strict security system, and some hackers can even enter. Therefore, in order to truly achieve complete security, it must be not connected to the Internet, and it is not connected to the Internet from beginning to end.
Tark wallet has the advantage of offline signature, avoiding private key connecting the network and reducing the risk of theft. Each transaction involves the issue of signature confirmation. The Tark wallet user holds the private key, and the transaction is not connected to the private key. The transaction is more secure. Tark wallet automatically opens the never-connecting the network mode during idle use, builds transactions and signatures at the cold end, and broadcasts transactions at the hot-end network, creating a strong protection shield for the token assets, completely eradicating network hacking and resisting asset risks caused by various reasons.
Third, the private key cannot be lost. Loss of private keys is the cause of the most loss of assets. The private key is to be copied on paper, to be copied correctly, and then placed in a place that will never be forgotten. And don't put the private key and wallet together.
As mentioned in the opening paragraph, the private key is only a small part of the digital wallet security field. Tark wallet's efforts in security construction have never been relaxed - the world's first dual-form cold wallet security protection model to protect the user's token assets; with advanced technology that surpasses the global main stream token asset wallet, the introduction of Silicon Valley's Top technological Innovation and Research and Development of Multi-person Cooperative Management function in the United States, greatly reducing the safety factor of the risk of the user's token assets.
To manage digital assets, you need a financial superman!
With the development of industry and technology, people's functions and requirements for digital wallets are getting higher and higher.
If you are a digital asset investor, what you value most is the security of the wallet, a wallet with poor security performance, which is likely to make your money become hacker's money; secondly, if you have a wide range of assets and use a single-currency wallet, you need to switch back and forth between multiple wallets and accounts.
At this time, the superiority of the Tark wallet, which combines two super features and six unique advantages, has become one of the hottest in the market.
Two super features - nothing is more important than anonymity and security
Anonymity and security are two of the top features of the Tark Digital Wallet.
The so-called anonymity, all transactions in the Tark wallet are open, which determines that it must protect the privacy of the trader, and no one can easily access to the trader's information. In a general centralized trading system, privacy is provided by trusted centers. All user information and transaction information are stored in the central database, and ordinary people cannot easily obtain the customer's information. Only the trusted center holds the information of everyone. Based on blockchain 4.0 technology, Tark's wallet is a truly decentralized product whose nature determines that no one can easily access the user's data.
In terms of security, Tark Wallet created the world's first dual-form cold wallet security protection model. It introduced the top technology innovation and multi-person collaborative management function of Silicon Valley in the United States, which greatly reduces the safety factor of the risk of the user's token asset and escorts the user's token assets!
In addition,When the wallet is idle, the network will automatically open the never-on-network mode. It builds transactions and signatures at the cold end, and broadcasts transactions at the hot end, creating a strong protection shield for the token assets, completely eradicating the network hacking and resisting the asset risks caused by various reasons.
Compared with the traditional token asset wallet, Tark wallet strictly controlled the payment and withdrawal operation, and the two password security management mechanisms of seed password + payment password prevent theft of assets and fraudulent use, cryptographic storage, never touch the network, secure verification and delete after you use.
Six advantages - financial superman think for you
Support multi-currency: Manage all high-quality currencies worldwide, support all ERC20-TOKEN, cross-chain support BTC, LTC, ETH, EOS, ETC, XEM, BTG, IPC, GOD, BCH, DASH, DOGE, QTUM, ERC20, BCD , SBTC, BCX, XRP, WA, AXC, FTCT, KMCC, CVT and other types of certificates that are circulating worldwide.
Second speed: based on atomic cross-exchange technology and cross-chain lightning trading of blockchain 4.0, atomic exchange is carried out on lightning channel to realize infinite high-speed transaction between any blockchain.
Multi-account system: Blockchain 4.0 technology gives users the right to truly master their digital assets and personal data, with the help of cryptography public and private key wallet account to become a unique digital identity. Tark Wallet creates multiple accounts with one identity, and does not need multiple tools to manage multiple private keys, and one identity can manage different passport assets.
Offline signature: Avoid private key connecting to the network and reduce the risk of theft. Each transaction involves a issue of signature confirmation. The Tark wallet user holds the private key, and the transaction private key is not connected to the network, making the transaction more secure.
Multiple verification: fingerprint, facial recognition and other verification methods.
Open third-party ecosystem: Support the entering of third-party applications, such as games, videos, shopping malls, live broadcasts, etc.
Financial expert and global payment - this is the era of TarK!
TARK Digital Bank - the terminator of traditional banks?
With the advancement of technological innovation, we are entering an era of transition in the relationship between consumers and banks, and the advantages of digital bank are slowly becoming more and more prominent.
The difference between traditional banks and digital banks
Traditional banks, from a micro level, can be seen as an institution that absorbs deposits and issues loans. Based on the trust of the bank, we deposit the assets in the bank. The bank can use the money to lend or make other profitable projects, but no one can guarantee that such trust will not deteriorate over time. Our assets are in the hands of third-party banks. Once a crisis of trust arises, no one will guarantee us the security of asset, we can only bear the losses ourselves.
The rise of digital bank is catering to a large number of consumer groups that have grown up in the computer age. Blockchain technology, artificial intelligence and technology strategies will provide people with more convenient and faster services, and better integrate into people's lives. We're getting used to going out with only one mobile phone. Through the breakthrough of information security, digital banks can avoid the central information repository with risk of leakage, and replace it with a decentralized information system that can be encrypted and decentralized. The emergence of Bitcoin is in line with the development needs of the digital age, making a decentralized digital payment system possible.
Tark wallet, with two super features and six advantages
The security, transparency and non-tamperability of the blockchain will change the core principles between the financial systems. The trust model between the future financial systems will no longer rely on intermediaries, and the banking business will be “decentralized” to realize real-time digital transactions. Tark wallet has achieved a major breakthrough in technology, fully reflects the spirit of blockchain in application, with two super features of anonymity and security, with six advantages of multi-currency, second-speed, multi-account system, offline signature, multiple verification and open third-party ecosystem; support payment, storage and transactions of multiple tokens, but also integrate games, communities, live broadcasts and other applications, it is a comprehensive blockchain platform system.
Tark builds digital bank and builds a new financial ecosystem
Digital bank will achieve its ambitious goals through encryption technology, distributed accounting, artificial intelligence and big data. As an important part of the digital economy and ecosystem, Tark Wallet is more efficient, flexible and profitable in structure. It will also provide artificial intelligence and big data analysis to provide an unprecedented customer experience while optimizing customer transaction costs and bank financing costs. There is no doubt that the birth of Tark Digital Bank will create a larger financial ecosystem. Whether it is insurance companies, brokers, smart investment consultants, credit card issuers, international payment service providers, P2P platforms can expand their financial systems through digital bank.
Tark, financial expert and global payment
Tark Wallet is the most direct application of several major financial scenarios, such as encrypted assets, cross-border payment and settlement, bill and supply chain finance, securities issuance and trading. In terms of cross-border payment settlement, Tark Wallet will abandon the role of intermediary bank, based on blockchain 4.0 cross-chain lightning technology, to achieve point-to-point fast and low-cost cross-border payment. According to McKinsey's calculations, from a global perspective, the application of blockchain technology in B2B cross-border payment and settlement services will reduce the transaction cost by about 40%, which will be a broad development market.
From the point of view of investors, Tark Digital Bank will bring many exciting investment opportunities, not only saving real estate expenses and a large amount of traditional IT maintenance costs, but also involving less human resources than traditional banks. I believe that with the development of technology, traditional banks will gradually disappear, and Tark Digital Bank will end the era of traditional banking. Let us wait and see!
You think only Ali has Agents of SHIELD? A higher level of security is here
On May 8th, according to the official announcement of Binance, the Binance exchange discovered a large-scale security vulnerability, and the hacker was able to obtain a large number of user API keys, 2FA codes and other possible information to steal the token assets. At 17:15:24 on May 7, the hacker stole 7,000 bitcoins from the coin-hot wallet at block height 575012.
After the theft of the coin, BNB fell 5% in half an hour and quickly fell below $20. Then Binance announced that, due to security vulnerabilities, Binance will take about one week to conduct a thorough security check, during which time the recharge and withdrawal will be suspended to ensure that the trading market is not affected.
Although Binance announced that the "SAFU Fund" will be used to fully bear the full loss of this attack, no user has any losses, but the impact of user panic caused by the coin theft incident cannot be eliminated in a short period of time.
Faced with the frequent occurrence of coin theft in trading platforms, people can't help but ask why Alipay will not be hacked by hackers.
According to relevant statistics, more than 400 million users use Alipay in China, and the total amount of user assets is immeasurable. This number should be more attractive for hackers, but why is Alipay not hacked?
According to the reason spread on the Internet, the reason why we can use Alipay with peace of mind is because Alipay has a department like Agents of SHIELD. In other words, it is not that hackers do not want to attack Alipay, but they do not have the ability to attack. It is said that the "Agents of SHIELD" will recruit hackers who attack Alibaba. If the hacker can break through the firewall, they will ask the hacker to work in Ali, offering a very generous salary. In addition, even if the last line of defense of the Alipay system was also broken, it was proposed that the transfer network was strictly regulated by the legal currency, which could not be taken away, and could be traced and lead to jail.
For hackers, attacking Alipay is a very unwise choice, not to mention the high level of difficulty, but also to bear the high risk. Compared with the attack Alipay, hacking the token trading platform in the black blockchain field is much easier. As long as there is a loophole in the token trading platform, it gives the hacker a chance. Due to the anonymity of the blockchain transaction, the assets of the trading platform can hardly be recovered after it is lost.
So for hackers, some trading platforms are comparable to "ATMs."
Nowadays, the popular exchanges are still in the development stage of centralization, and the incident of coin theft is almost inevitable. In addition to being attacked by hackers, the situation of inside job of the trading platform has also occurred from time to time. Then, how should the asset security of the token holders be maintained?
The emergence of the new digital wallet TarK wallet provides a new idea for solving the problem. The TarK wallet is a decentralized wallet developed and based on the fourth generation of blockchain technology. In addition to storing the token assets, it also supports payments of all token assets and cross-chain transactions. Tark combines two major features of anonymity and security, as well as six advantages of multi-currency, second-speed, multi-account system, offline signature, multiple verification, and open third-party ecosystem.
Today we are going to emphasize the security protection advantages of the TarK wallet. Tark wallet is the world's first dual-form cold wallet security protection model. It introduces the top technology innovation and multi-person collaborative management function of Silicon Valley in the United States, which greatly reduces the safety factor of users’token asset and can escort the user's token assets!
In addition, Tark wallet will automatically open the never networking mode during idle use, build transactions and signatures at cold end, conect the network and broadcast transactions at hot end, to create a solid protection shield for the token assets, completely eradicate network hacking and resist asset risk caused by various reasons.
TarK wallet provides you with stronger security protection than “Ali’s Agents of SHIELD”, so you can stay away from the coin theft of centralized trading platform!
