[News]What is NFT? Why is it popular? 3 minutes to learn non-homogeneous tokens lazy bag

What happened in March 2021? An NFT artwork sold for sky-high prices

2021/3/12, at Christie’s auction site, there was an encrypted artwork Everydays: The First 5000 Days. Until the last two hours of the auction, bidders continued to flood in, and finally paid 70 million U.S. dollars (approximately NT$1.9 billion). The astronomical price of yuan) hit the hammer, setting the highest price in the NFT art market.

This also allowed Beeple, the author of this work of art, to be promoted to one of the three most valuable living artists in the world. It also makes the world aware that the original purely digital works will replace physical works and become tools that can be invested and preserved in value.

What does NFT mean? When you read this article, first of all congratulations. This means that you have opened the door to the "coin circle" and are one step closer to investment opportunities. As for how to trade NFT products? Where to trade? You can refer to this article- NFT platform introduction .

1 What is NFT?

First of all, Bitcoin (BTC) and Ether (ETH) that we often hear are homogenized tokens, and NFT is a non-homogeneous token. Let's take a look at the characteristics of these two terms?

-Fungible Token:

1. Fungibility: Each cryptocurrency has the same value and the same function. The BTC in my hand is the same as the BTC in yours. It can be exchanged at will, and it can be used for trading without a separate price.

2. Severability: Continue to use BTC as an example. The price of a BTC currently exceeds 1 million Taiwan dollars, but the amount at the time of transaction is often less than 1 Bitcoin. At this time, we can choose to trade only 0.1 BTC, or 0.00001 BTC does not need to be traded in integers and can be split infinitely, which is the divisibility of homogenized tokens.

3. Consistency: Due to the above two characteristics, it has the same recognized value as the legal currency used daily, but it does not need to have different denominations of legal currency banknotes. It supports split transactions and makes homogenized tokens usable for transactions. Good choice.

-Non-Fungible Token (NFT, Non-Fungible Token):

1. Not substitutable: Each NFT is unique and irreplaceable. For example, the master tape of Seiko Takahashi must be unequal to the master tape of the young actress who just debuted, nor can it be replaced by other actresses.

2. Not divisible: If the master digital file of Takahashi Seiko is a NFT token, this token cannot be divided into smaller units for trading, and the unit of each transaction is one, which means that you get this NFT people have a complete mastering of all parts of Takahashi Seiko.
3. Uniqueness: Due to the above two characteristics, the NFT of the "Takahashi Sage Master Band" also has anti-counterfeiting functions and is a digital collectible that can be circulated.

2 NFT protocol ERC-721 / ERC-1155

When I introduced the Little Fox MetaMask cryptocurrency wallet before, I mentioned ERC-20, which is the earlier token specification protocol of the Ethereum blockchain . For example, there are two tokens on the Ethereum platform that are issued with ERC-20. , The two tokens can be exchanged freely, and the tokens here refer to homogenized tokens.

What is Smart Contract?

In one sentence, a smart contract is a "special agreement that can be automatically executed on the blockchain". To put it bluntly, a smart contract is a string of program codes on the blockchain. When special conditions are met, it will be triggered to execute , Neither is smart, nor is it a contract, nor is it legally beneficial.

Since the code on the blockchain will not be tampered with, fully open and transparent, and will not stop operating, it means that no one can change the content and execution of the smart contract. The value of the smart contract is to provide better protection and enforcement for both parties to the contract. , Ethereum Developer Agreement ERC (Ethereum Request for Comments) is a smart contract.

What is ERC-721?

If ERC-20 is used to issue a general homogenized cryptocurrency, ERC-721 is the first standard protocol for non-homogeneous token NFT in Ethereum. Compared with ERC-20, ERC-721 has more diverse application scenarios. , Including games, intellectual property, physical assets, identification, financial documents, ticketing, etc. ERC-721 was created by Dieter Shirley, CTO of CryptoKitties, and is currently used in CryptoKitties, Decentraland and other projects.

The tokens issued through ERC-721 are non-homogeneous tokens, and it is ERC-721 that gives the non-homogeneous token NFT uniqueness. All digital assets: paintings, bonds, houses or cars, in ERC-721 Under the agreement, the security of ownership, the convenience of ownership transfer, and the immutability and transparency of ownership history can be guaranteed.

In addition to ERC-721 and ERC-20, the future development of blockchain will not leave another growing protocol ERC-1155.

What is ERC-1155?

At present, whether it is the homogenized token agreement (ERC-20) or the non-homogeneous token agreement (ERC-721), when creating a token, each requires their own independent smart contracts. For example, game developers may need to create thousands of token types. If the old independent token protocol is used, it will not only limit the interaction between tokens, but also consume a lot of resources on Ethereum.

Through ERC-1155, smart contracts can transmit multiple types of tokens at once. In addition to saving gas fees, multiple types of tokens can also be directly traded based on this protocol, without the need for individual tokens to approve different independent ones. Only after the contract can be traded, the interaction between assimilation tokens and non-homogeneous tokens can be directly carried out.

3 NFT anti-counterfeiting and confirmation

Because NFT has the above-mentioned uniqueness and inseparability characteristics, some areas of NFT are very suitable, such as artwork, games, electronic deposits, and identity authentication. In addition to the cryptographic confirmation of assets (asset identity confirmation) through NFT, the trust problem can be solved. On the other hand, traditional physical assets have passed such authentication, which greatly improves the liquidity of assets and integrates painting, calligraphy, sculpture and other arts. The products are stored on the blockchain in the form of NFT, which not only strengthens the anti-counterfeiting requirements of the collectibles, but also improves the efficiency of physical rights confirmation and transaction circulation.

Our conclusions about the future of NFT:

When it comes to NFTs, most people think of games, artworks, and collectibles. This is still a niche market, especially IP-type NFTs, whose value basically corresponds to the value of IP in the real universe. The valuable IP in the real universe naturally has the advantage of being easy to circulate and being accepted by the next buyer; the IP that originally had no value in the real universe may also end up with no buyer accepting it for 1 yuan. And when the price of IP-type NFTs has been hyped up to a certain extent, this type of NFT will lose its advantage in trading circulation.

NFT has unique attributes, allowing NFT to be more widely used in specific scenarios and services. For example, Yinsure Finance uses NFT tokenization for insurance services. Each insurance policy is an NFT token. In addition to holding it on its own, these tokens can also be used to trade on platforms such as Opensea and Rarible .

Following the Dogecoin boom, two "Dogecoins" Akita Inu and Shiba Inu coins have also increased in price

There is an upsurge in the cryptocurrency circle. With the skyrocketing of Dogecoin, cryptocurrencies related to dogs have also skyrocketed in recent days. Also included with the Shiba Inu marked Shiba Inu currency (SHIB), as well as new members of the "Dog currency" of Akita dogs currency (AKITA).

The picture shows the official website of SHIBA TOKEN. Shiba Inu’s development team even claims to be a "Dogecoin killer." (Screenshot of Shiba Inu Coin official website)

On the anniversary of Dogecoin's April 20th, the prices of the two dog currencies also rose. Akita Inu coin increased by 7,417% in one week and 10,628% in 30 days; Shiba Inu coin also increased by 668% in one week and 2,536% in 30 days. And as Dogecoin has soared again recently, the price of "Canine Currency" has also soared.

According to the websites of Shiba Inu Coin and Akita Inu Coin, both currencies are decentralized experimental tokens sent from the community. 50% of the total supply will be locked in Uniswap transactions, and the remaining 50% will be destroyed. The development team will not hold any tokens in their hands. The purpose is to ensure that the price of the currency is stable and there will be no possibility of official manipulation of the price.

The picture shows the price trend of Akita Dogcoin. Since its launch, the Akita Dogecoin has surged in April and May following the increase of Dogecoin. (Screenshot of CoinMarketCap)

Akita Inu Gohei "Akita Inu Amiji"

Akita Dogcoin was launched on Uniswap in January and has now entered 7 exchanges including Huobi and MXC Matcha. The Akita Dogcoin development team has been cooperating with Polarfox Ecosystem and Avalaunch to create a community called "Akita Dog Network", which will continue to develop through the use of small sponsorships for Akita Dogcoin.

It is worth mentioning that the Akita dog also introduced currency Home currency, as well as self-proclaimed "dog coins CEO" of Musk (Elon Musk). The development team claims that Akita Dogecoin was inspired by Dogecoin and the team hopes that Akita Dogecoin will also rely on the power of the community to drive its own development.

Shiba Inu coin calls itself ``Dogecoin killer''

As for Shiba Inu coins, they even call themselves "Dogecoin killers." Shiba Coin intends to launch its own decentralized trading platform ShibaSwap and establish its own ecosystem, and the future blueprint published on its website intends to get involved in the NFT platform.

According to the development team, Shiba Inu Coin will provide LEAH as a reward for liquidity mining, and the blueprint for another BONE currency will be announced when ShibaSwap goes online.

Although both Shiba Inu and Akita are still in the early stages of development, the recent media exposure of the use of Dogecoin has greatly increased. The two currencies have also attracted the attention of investors and participated in the community to promote development.

[News] Female stock god Wood is no longer attractive? Ark investors run away

After some of the stock selling pressures that Ark Investment Management Company heavily no pledged , the outflow of funds from three index equity funds ( ETFs ) of Cathie Wood, the "women stock god" in charge of the company , set a record for the most in the company's history. .

According to Bloomberg's data, the company's flagship fund product Ark Innovation ETF (transaction code: ARKK) outflowed US$465 million on the 23rd. Investors withdrew US$202 million from the Ark Biogenetic Innovation ETF (ARKG), and Ark Next Generation Network ETF (ARKW) also flowed US$119 million.

As Ark’s assets under management reached 60 billion U.S. dollars as of last week, these outflows are only a small part of it, but this is the largest capital flight that this company founded in 2014 has encountered in history,] And this time Outflows are more than three times higher than the previously written record.

The main reason why Wood's ETFs have been hit is that US technology stocks are under heavy selling pressure, which has caused the company's most-owned Tesla to fall. Wood told Bloomberg TV on the 23rd that she would like to see this correction and that she bought more Tesla shares on dips.

According to a Reuters report, Ark said on the 24th that when Tesla's stock price plummeted, the company had bought more than $171 million worth of Tesla shares; Tesla's closing price on the 23rd was the first time this year to fall below $700.

According to the official website of Ark Investment Management, the company bought Tesla in three batches this time, with the purchase value of US$124 million, US$39 million, and US$8 million. In addition, Ark also sold TSMC (2330) shares worth US$126 million on the same day .

Ark's innovative ETF with assets of US$26.6 billion achieved triple-digit performance last year and was one of the best performing ETFs last year. However, the fund is implicated by Tesla, and its performance this week has fallen sharply. After all, Tesla accounts for 10% of the fund's holdings, and some of the company's stocks have also fallen sharply.

After a large inflow of funds last year, more and more people have begun to short this fund. According to data from IHS Market, Ark's short order balance currently accounts for more than 3% of the number of tradable stocks, setting a record high.

[News]Vaccine diplomacy is the vane of structural competition between China and the United States

1. The direction of Sino-US structural competition remains unchanged
The new crown epidemic accelerated the deterioration of US-China relations at the end of Trump's term. It not only obliterated the temporary easing of the first phase of the trade agreement in early 2020, but also extended the hostility between the two sides to the entire government and society. It even launched a full-scale confrontation in science and technology, education, finance, and ideology, which made all the geopolitical hot spots surrounding the rising China even more tense. Except that the Sino-US and global trade links are more dense than those of the Cold War and earlier, and it is difficult to "decoupling" immediately, in all other respects, the confrontation between the great powers is even worse than the confrontation between Britain and Germany on the eve of 1914.
Although Trump lost the election and Biden accurately chose to talk to Xi Jinping during the Lunar New Year after taking office, the Biden team then, as indicated before the election, fully launched the "America is back." The seven major industrialized countries (G7), the Four-Party Security Dialogue (QUAD), and the upcoming "Summit for Democracy" (Summit for Democracy) will regroup from the aforementioned "full-field" and various aspects to deal with the "Chinese challenge." Obviously, the conspiracy theorists who promoted "China Biden" were completely wrong. As Secretary of State Antony Blinken said, the direction of the Trump team to check and balance China is no problem in terms of US interests. The problem lies in the wrong "method" of Trump, Mike Pompeo and others in competing with China.
2. Global anti-epidemic cooperation is inadequate, and rich countries accumulate criticism
The epidemic is the short-term highlight of this competition. From the perspective of "human security," China and the United States ostensibly agree that, just like climate change and emission reduction, joint epidemic prevention should be an area that transcends national borders and some of the two powers should cooperate. And I believe that these topics not only took up some time during the two-hour call on Xi’s, but also a few topics where both sides can treat each other friendly. However, up to now, the two sides have not seen any follow-up communication and promotion at work levels in relevant fields. Instead, people have seen that the two major camps of China and the United States continue to compete with each other and strive for support in relevant international forums.
Although the Chinese medicine Coxing CoronaVac vaccine launched earlier and the national medicine BBIBP-Corv vaccine launched later are traditional inactivated vaccines, they have been administered more quickly and more in developing countries in Asia, Africa and Latin America. The health authorities of some countries have not only Officially approved for listing, leaders of Turkey, Indonesia, Chile, and Peru also publicly vaccinated. While the European Union complained that it was unable to purchase the Oxford vaccine produced by the Brexit Britain, Chinese vaccines entered Eastern Europe's Hungary and Serbia. Xi Jinping also proposed cooperation with Eastern European vaccines at the China-Eastern Europe 17+1 summit. Although the total dose of foreign aid is not yet known, Beijing officials pointed out that it has provided "vaccine assistance" to 53 developing countries and "exported vaccines" to 22 countries.
3. China's proposal of "Priority to Developing Countries" creates propaganda pressure on the West
The Secretary-General of the United Nations and the Director-General of WHO have repeatedly complained about the uneven distribution of global vaccines, which will delay the time limit for the world to get rid of the epidemic. Countries such as the United States and the United Kingdom have sufficient R&D technologies and resources, and rapid vaccination actions. Foreign media quoted Western NGOs as saying that the number of doses scheduled and stockpiled in the United States, the European Union, the United Kingdom, Australia, Canada, and Japan has far exceeded the need for 1 billion doses. However, its European allies and Canada suffer from the dilemma of "ordering but not getting the goods." Except for the two small and wealthy foreign countries with the highest vaccination rate in the world, Israel and the UAE, the major powers are led by the United States and Britain. In NATO, there is a peculiar phenomenon that Turkey leads Germany and France. With a population of less than 40 million, Canada has ordered 400 million doses of vaccines, but the supply is short. For example, the Russian "satellite" vaccine came out earlier and was used in Argentina, Venezuela and other countries, and was approved by India to co-produce it. However, the United States and Ukraine have banned its use and sanctioned Russian institutions participating in research. The chaos in anti-epidemic cooperation within the Western bloc and the resistance to China and Russia bluntly prove the important role of "national priority" and "bio-power" in geopolitical confrontation.
When attending the Security Council Ministerial Meeting on Vaccine Issues on the 19th, Chinese Foreign Minister Wang Yi pointed out that the essence of the vaccine deficit is "capacity deficit" and "distribution deficit", and requested the implementation of the WHO-led anti-epidemic and "vaccine program" (COVAX) It should implement the "developing country first" principle, and earlier claimed that it would provide COVAX with 10 million doses to "urgently needed developing countries." In May last year, the United States, Australia and other countries proposed to "independently send an investigation team" to investigate the epidemic in China at the World Health Assembly. The proposal was amended to be an inspection "under the leadership of the WHO." After the visit of the delegation in February this year ended the field investigation in Wuhan, the members of the expert group ruled out the possibility of the virus from the Wuhan virus. They also pointed out that the epidemic may appear in other parts of China in October 2019 or earlier, reducing the pressure on China issues; plus Beijing has targeted the principle of giving priority to developing countries, which is believed to have exerted tremendous pressure on the US, Britain and Western groups.
4. The U.S., Britain and G7 make urgent moves, hoping to win back the moral high ground
When Biden participated in the election, he promised that the United States must return to non-traditional security multilateral mechanisms such as the World Health Organization and the Climate Change Convention. This is an effective way to respond to China's challenges. When Brinken attended the Security Council vaccine ministerial meeting, he also promised to allocate 200 million US dollars to the WHO. If it can be fulfilled, it will be able to make up the 80 million US dollars arrears by Washington. The G7 summit held at the same time also issued a statement saying that "including the acquisition of the New Coronary Pneumonia Tool Acceleration Program (ACT-A) and COVAX's US$4 billion in financial assistance, the G7 will provide assistance to reach US$7.5 billion." It has always been concerned about Africa. French President Emmanuel Macron called on the United States and Europe to give 5% of its production to developing countries. This was responded by German Chancellor Angela Merkel. The United Kingdom, which is the leader in vaccination, also promised to give priority to the remaining vaccines. What remains is that the pragmatic approach is quite different from China's "feat" of assisting Tanzania to build a railway during the Cultural Revolution. (According to statistics, the United States has administered more than 40 million doses of vaccines, the United Kingdom, with a population of more than 60 million, has also administered 17 million doses, and Canada, with a population of 35 million, is still less than 1 million doses, with a population of 1.4 billion. China has administered approximately 22 million doses.)
In fact, Western Groups are still far ahead of China in terms of technology and resources. The reason for being passive on the issue of the epidemic is that apart from the fact that the regime system is different from that of mainland China, it must give priority to meeting the expectations of the people of the country under the pressure of public opinion. What is more important is that the "new right" created by the economic problems of various countries in recent years has used populist The agitation inspires the principle of “domestic supremacy”, which not only greatly limits the strategic space for progressives to promote “globalism”, but also gives Beijing an opportunity to alleviate the incomprehension of the “third world” on the outbreak of the epidemic on the mainland, and the rejuvenation of China. Worry.
If Washington and London are only committed to consolidating their surveillance programs on China in India, they ignore that India can still conduct naval exercises with Russia and Iran; or block the Chinese media mouthpiece, but fail to pay attention to the historical perspective and think that Universal has the problem of double standards; or strengthening the joint operation of the "four-party dialogue", but underestimating the autonomous needs of the ASEAN, South Korea, and the island countries of Oceania. To ensure structural competition with China, we will have to experience a long and full of crisis. process.

[News]Copper breaks the $9,000 mark for the first time in 9 years

 (Central News Agency, London, 22nd Comprehensive Foreign Telegraph Report) The price of base metals has soared today. Among them, the price of copper has exceeded US$9,000 per ton, a new high since 2011. The market is optimistic about the economic recovery from the epidemic, which may cause a historical shortage of brass. Push up the price of copper and move towards a record-breaking consecutive monthly increase.

Bloomberg reported that the three-month copper futures price on the London Metal Exchange (LME) once touched US$9,187 per ton, the highest since 2011, and reached US$9141.050 at 11:02 am Singapore time. China's Shanghai Futures Exchange, copper futures prices rose by the limit today.

The prices of other metals also rose. The price of nickel futures on the London Metal Exchange hit US$200,10 per ton, and the price of tin also hit a high since 2011.

Copper prices have risen by more than 3% today, and this month has entered an unprecedented 11th consecutive month of gains. The market expects that after the epidemic crisis, short-term supply may not meet demand, and metal prices are soaring. Not only has the outside world increased speculation about the super cycle of new commodities, but with the economic recovery, it has also raised doubts about rising prices.

Shanghai Jinxin Futures analyst Jia Zheng said: "Under the anticipation of a new cycle of global inflation, market sentiment is high. Chinese investors return to the market after the New Year holiday and are waiting for more measures in the United States and Europe. Due to the travel ban. Boosting consumption, China's demand exceeds expectations."

[Make money online]Usertesting.com

Like most of us, you may have commented on how confusing some websites are and how good others are. You don’t want to complain to your spouse or friends. How do you want to comment to the website owner and get paid from critics?

I do it, so can you. In fact, you can earn per hour to $ 30 as a website tester .

I have been a search engine evaluator for a similar job for several months and it is great in some ways (you like to work from home, $12 to $15 an hour). But I have to judge search results based on strict criteria set by the company that hired me. As a website tester (also called a website evaluator or usability tester), I can criticize the website according to my own standards. My honest opinion as a consumer or user of a website is usually what the client wants. This makes work easier.

As you can see, the company wants to understand how real people interact with their website to reduce their confusion, easier to navigate and more attractive. To this end, they turned to businesses that maintain tester teams-people like you and me. When you register with a website evaluation company, you will download some software, and when tasks are available, you can view website actions on the mouse, and the number of clicks, keystrokes and verbal comments are all recorded as videos. There may be several questions to answer afterwards, but the whole process usually takes 15 minutes or less.

What assignments did you get as a website evaluator?

This morning I received from UserTesting.com e-mail, which said testing is available. I logged in to my account, put on headphones, and a minute later I was viewing a sports website for my children and their parents. For the next five minutes, my job is to view all the content, click on the navigation links, and then talk about what I have been seeing.

Then I clicked the "Finish" button, and went to the kitchen for a cup of coffee, while uploading a "video" (my audio and screenshots) (it took a few minutes). For this "usability study", I will be paid $10. Not bad, right?

Sometimes short-term tasks only cost $3, and not all tests are the same. Many involve describing your experience when viewing a website, but the second one I did today is completely different. It requires me to group navigation links together and name the boxes I put in. Informational posts are placed in a box named "Articles", and links such as "Contact Us", "Our Mission" and "Team Members" go into a box named "About Us". The owner of the site obviously wants to help organize the site based on how the average user might want to see it. I put 40 links into six boxes. It took ten minutes and I will get a task of $10.

The good and bad of working as a website tester

I wish I could complete this work more frequently, but the tests I did today are the first time I can use them, and I only did it six or seven times in the last month. This is the biggest disadvantage of this type of work. As explained by user testing, “because this is a high-paying opportunity, the number of user testers in our database exceeds our job opportunities.” On the other hand, if you are hired by these website evaluation companies, you may be in Get enough work between them to get a pleasant part-time income.

When your demographics match the target audience of the site you are testing, you can get homework, so you may get more revenue than mine. I have rejected quite a few tests or been disqualified because I don’t play this or that video game, or I don’t plan to buy a major device next year, etc.

With this in mind, here is a tip: Please be sure to fill in your personal information completely so that you don’t waste too much time answering questions, just to find out that you are not eligible to take the exam.

In some cases, I did not respond quickly enough to notification emails, so when I logged in, the available tests were offered to others. After logging in to my account, I saw the test come and go in a few seconds-fast enough without sending email notifications-so it might be helpful to visit your dashboard several times a day, just to see if it's available s things.

How to qualify and be hired to test a website

Companies that do this have their own needs, but here are some common qualifications they almost all need:

• You must be at least 18 years old
• You need to have a computer and microphone
• You need a broadband internet connection
• You will fill out a form with demographic information (your age, gender, computer experience, etc.)
• You (probably) must do a sample test

One testing company may need more testers of a certain age or income level, while another may be looking for self-employed or retired testers. In other words, if you are not employed by one person, please apply for the next one on the list.

To continue as a website evaluator, you must do a good job. Customers served by your employer will rate you, and getting additional tasks depends on whether you get a good score. Usually, customers want you to keep talking to the microphone while using their website and be clear about what you are doing and what you think.
