Tex digital currency
Yesterday, I went to the electronic reading room. Not long after I plugged in the USB flash drive, the teacher suddenly asked everyone to unplug the USB flash drive. Some students found that all the files in the USB flash drive could not be opened, and there were two more documents asking for money
so everyone rushed to check, as long as the U disk inserted in the school computer were poisoned, large-scale computer poisoning occurred in the evening
a lot of people's information and graation thesis are in the computer. I really feel that hacker's behavior is disgusting. For the sake of money, regardless of the future of students, teachers' lifelong scientific research achievements...
hope to catch criminals as soon as possible and give them severe punishment by law
this virus will scan windows devices with open 445 file sharing port. As long as the user's device is on the Internet, hackers can implant blackmail software, remote control Trojan horse, virtual currency mining machine and other malicious programs in computers and servers
some security researchers point out that this large-scale network attack seems to be deployed through a worm application, and wannacry can spread among computers. What's more terrible is that unlike most malicious programs, this program can replicate and spread on its own in the network, and most of the current viruses still need to rely on the successful users to spread by cheating them to click the attachment with the attack code
the attack has affected 99 countries and as many as 75000 computers, but because the virus uses anonymous network and bitcoin anonymous transaction to obtain ransom, it is very difficult to track and locate the originator of the virus

extended materials
the project side of the capital disk will generally carry out "gorgeous" packaging for the project by wantonly publicizing the blockchain technology and advocating that the team is a foreign senior technician, and carry out multi-channel promotion for the capital project online and offline through publicity such as high-yield and stable profit without loss, so as to attract new funds. Lin Xiao said bluntly, "from the current point of view, the project's favorite is the old man and Xiao."
when the investors' funds are in place, the project party will not harvest immediately, but will choose to smash the plate when the "leek" reaches a certain volume and the currency price rises to a certain high level
in the first wave of market smashing, the project parties usually operate by selling. They will control the decline of the currency price, but they will keep in the range where the user has a loss and is not too serious. For example, with an investment of 10000 yuan and a loss of about 1000 yuan, the project side can realize its own cash out without causing too much impact on the "chives"
Before the era of blockchain, Nick Saab first proposed the concept of smart contract in 1996: a set of agreements defined in digital form, including agreements on which contract participants can execute these agreements< the basic idea of smart contracts is contracts (special transactions) that can be executed automatically (event driven) and written in code form on the blockchain
since the establishment of Ethereum smart contract, more than 90% of the contracts have been used to issue tokens, and the implementation of relevant business scenarios is still good. What is the future of smart contract? Here you can see the Bytom chain that just released the news and launched the smart contract. As the first public chain project to release AI consensus algorithm in MIT, Bytom, the original chain, released an intelligent contract based on utxo model on the 26th after the main network was successfully launched in April
different from Ethereum smart contract built on account model, Biyuan chain is the first public chain in the whole blockchain instry to build smart contract on utxo model. Biyuan chain also transforms and deepens utxo to support the operation of multiple assets. In addition, compared with the original chain, the smart contract adopts its own equity language, which is a Turing complete and interpretive high-level language. It can easily compare the assets on the original chain for operation, and flexibly integrate into various asset business scenarios
in addition to the release of contract language, more than the original chain has also released multiple contract templates, which are directly attached with clear business meaning. From these contract templates, we can directly see the scene of future commercialization landing, and can extend the imagination in a wider range
currency transaction contract
through this contract, users can trade a variety of assets in Biyuan chain and other people without going through a centralized organization. That is to say, some assets can be locked through the contract. Only when other users enter the specified amount of assets, can they unlock these assets
for example, a decentralized exchange is built on the basis of contract, through which the two parties who want to exchange different assets in different currencies can be matched directly. The transaction speed is fast, and only a very small transaction fee is charged
third party trusteeship contract
under the contract template, users can transfer the specified assets to the third party's account, and the third party decides whether to call the specified account or return to the original account. The third party trust trust trust agreement stipulates that the third party institution can only transfer the assets to the designated account or return to the original account, which prevents the possibility of the third party account from stealing. In the business scenario, it can be expected that an asset custody platform can be built on the basis of the trusteeship contract of the third-party trusteeship institution in the future, which can ensure the custody, transaction and circulation of users' assets through the double trust of the trusted third party and the contract
mortgage contract
that is, the borrower will borrow the assets, and the lender will mortgage the assets into the same contract, and the lender will obtain the borrower's assets. If the lender fails to return the borrower's assets at a certain block height, the borrower will automatically obtain the lender's mortgage assets
call option contract
in this contract, the asset issuer can sell an asset at a certain price, and the buyer can buy the asset at that price. When it exceeds the height of a block, the asset will automatically return to the asset issuer
from the above design of smart contract, we can see some advantages:
firstly, a variety of templates with business meaning provide convenience for the upper layer to build DAPP, and some core business processes can be realized without too much development; Secondly, compared with the original chain, smart contracts issuing assets have templates. Compared with different developers, the security risk under the standard template is much lower. In addition, the contract will be invoked as a sub contract than the original chain when creating the intelligent contract. The contract template changes or errors that will be invoked in the future will not affect all completed intelligent contracts, which is of high security value for the early intelligent contracts. p>
we can understand that using the ratio chain of the extended utxo model butxo to interact with assets as a new form of utxo not only avoids the emergence of data overflow and other vulnerabilities in the Ethereum account model, but also has flexibility, diversity and controllability
for Biyuan chain, the release of smart contract also marks the determination of its core, which will further promote the commercialization of the project
the exchange rate of RMB to Iranian Riyal is 6469.228620
the exchange rate of Iranian Riyal to RMB is 0.0002
since the 1970s, the US dollar and oil have been bound together to form & quot; Petrodollars & quot; After the combination of commodity currencies, almost all oil countries have to look at the US dollar. If they do not comply, they will face sanctions and restrictions from the US dollar, and then lose the channel to carry out normal oil trade and commodity trade with the world. The US dollar has been creating an unfair and unreasonable monetary phenomenon. Among them, the US dollar's restrictions on Iran, an oil country, have been very obvious since 2018. However, the Baijia research team of BWC Chinese network has noticed that several latest developments show that Iran has broken and is continuing to break through the dollar limit
oil tankers loaded with Iranian oil usually turn off their transponders when loading to avoid being found, and can only be tracked near the ports of Oman, UAE and Iraq, Reuters said on March 9, quoting refrinitiv analysts. According to reports, most financial transactions are concted in RMB or euro to bypass the US dollar restrictions. In other words, Iran's oil exports did not stop because of the restrictions of the US dollar< In the past 14 months, Iran has delivered about 17.8 million tons of oil to major Asian markets, according to the data of refreshiv oil research. January and February this year saw record trading volumes. According to the latest news, in addition to RMB trading in Iranian oil, Reuters also mentioned the euro. According to the analysis, Iranian oil not only broke the dollar limit and was transported to China, but also to some European countries. The core logic behind this is that European countries are also working with Iran to de dollarize. This is no doubt a surprise to the dollar
a new development is that according to the news released by the Iran Switzerland Joint Chamber of Commerce quoted by Iranian media presstv not long ago, according to the shta trade mechanism, the first transaction between Switzerland and Iran shows that the cooperation between Iran and Swiss enterprises has bypassed the US dollar. Iranian media also said that at present, four Iranian banks are negotiating with Germany, France, Britain, Russia, Switzerland, Austria and other countries on the use of cryptocurrency in trade settlement and financial transactions
as early as a year ago, more than a dozen European countries, represented by Germany, have joined an instrex mechanism to help Iran's economy conct normal business settlement. The European Central Bank said that the digital currency scheme supporting avoiding swift is expected to make a breakthrough in a few months. It is obvious that the US dollar's plan to restrict Iran's oil exports and try to cut off Iran's currency and commodity transactions with the outside world has failed. The sovereign cryptocurrency solution in the form of blockchain technology undoubtedly makes the US dollar more headache
it is worth noting that the Central Bank of Iran has established a blockchain currency research laboratory to develop national cryptocurrency supported by local currency. It is reported that the head of Iran's export guarantee agency said two weeks ago that at present, the funds managed by the agency have replaced the banking system, and tried to clear the obstacles faced by Iran's engineering and technical service departments by issuing guarantees. At present, Iran has issued more than 1000 cryptocurrency mining licenses, This could boost trade, including oil, using cryptocurrency to import goods.
in addition, Iran has also taken other measures, such as officially taking RMB as one of its foreign exchange currencies, replacing the US dollar. Moreover, Iran will also cooperate with relevant enterprises of China under the RMB exchange rate and the implementation of Iran's digital currency, including increasing cooperation in non energy aspects such as technical services, urban planning and infrastructure, investment and tourism, which will not only crowd out the existence of US dollars in Iranian business, It will also increase the breadth and depth of RMB digital financial assets in the global economy, and also play an important role in the transformation of the international settlement system< br />
in addition, Iran has officially changed its official currency Yar into Turkmen, although the change of Iran's official currency has some negative effects. The change of official currency will cost US $160 million, but Iran can save us $11.5 million in money printing cost every year. Experts said that this move is undoubtedly effective for Iran's economy to leave oil revenue, and it is also a strong counterattack against a series of economic sanctions imposed by the United States< br />
and Iran will follow Venezuela's example to deal with the economic sanctions of the United States and implement crypto sovereign digital currency like petrocurrency. Iran, in the Ministry of instry, mining and trade, implements a calculation method for densified stopes. This not only increased Iran's exports of steel and copper, but also led to an increase in its agricultural and petrochemical procts. The increase of Iran's export of these resources has greatly made up for the loss of oil export and made a good transformation of Iran's hard currency resources. What's more surprising is that although the stock markets of many countries around the world are in a period of substantial adjustment, Iran's stock market has risen to an all-time high e to the effective monetary reform, with the main index rising to nearly 1 million points (Iran's tedpix index rising to 978019.48 points). Moreover, the difficulties faced by Iran's engineering and technology department in digital cryptocurrency have been further solved, Speed up Iran's circumvention of sanctions on its sale of oil and non crude procts to the United States. Although Iran did not disclose the details, it can be seen from the threat from the United States to step up sanctions against Iran and Venezuela that Iran has indeed made great achievements in bypassing the U.S. bank clearing system and avoiding U.S. economic sanctions.
