2021 year ,NFT Completely famous , Except for celebrities 、 Outside the stars , tencent 、 NetEase 、 Ali and other big factories have entered the market one after another , Artwork 、 collection 、 Copyright 、 music 、 Games etc. , All things can be NFT.

NFT What is it? ? His full English name is Non-Fungible Tokens, In Chinese, it is generally translated as " Non homogenous tokens / There is no substitute for tokens ", Tell the truth , I don't understand . Here's what Wikipedia says about him ,

NFT It is a concept that exists relative to the homogenization of tokens . Homogenizing tokens , namely FT(Fungible Token), They can replace each other 、 Freely divisible token, For example, a bitcoin in your hand and a bitcoin in mine , There's no difference in essence , This is the homogenization token , and NFT It's the only 、 Indivisible . In short ,NFT Used to represent digital assets , It's video 、 Audio 、 picture 、 Artwork 、 Unique encryption token for game props, etc , It is an item belonging to the blockchain .

for instance , Buy one with bitcoin NFT, It's equivalent to buying a painting in RMB , Buy a prop with game currency , And it can also bring its own anti-counterfeiting logo , I seem to understand .

If it comes to NFT, There may be two things that most concern us ordinary people , The first thing is NBA Player curry Howe threw 18 Million dollars to buy NFT, This is the blue monkey . Although I can copy and save this picture , But the real owner of this blue haired monkey is curry . Like art in real life , Everyone can have van Gogh paintings 《 Fifteen Sunflowers in the vase 》1:1 Copy version 、 posters , But there is only one real original work , In the hands of only one person ,

The second thing is that Jay Chou used to ins Write about your boring ape stolen , Here is the monkey ,

The boring ape that Jay Chou stole is probably 42 Thousands of dollars , When the boring ape project was just launched , The price of these monkey pictures is 200 dollar , Up to now, the price has doubled 2000 About times .

There are basically only two ways to steal this monkey , The first is to crack the key . Mr. Zhou's NFT It's in Ethereum wallet , So steal this monkey NFT, You have to crack his Ethereum secret key first . Ethereum secret key , It's a bunch of 256 Binary number of bits , Everyone has 2 Maybe (0 or 1), Guess all right 256 A digital , The most violent attempt is 2² ⁵⁶ Time . How big is this number ?2² ⁵⁶=1800 Billion * 1800 Billion * 1800 Billion * 1800 Billion . Even hackers use supercomputers , It is very difficult to crack him . So hackers are likely to use the second method , That is, luring into a disguised phishing website , Enter account number and password , Easy to steal .

The boring ape that Curie and Jay participated in is the hottest in the world NFT One of , At present, the lowest price of a single product in the whole network is 108 Ether money , Equivalent to USD 35 ten thousand .

But on the other hand , although NTF The earnings are high , Encryption is advanced , But we can see from the above case , The cost of theft is extremely low , This may be NFT Problems that need to be solved urgently in the future .

4 month 13 Japan , Chinese Finance Association of Internet 、 China Banking Association 、 Jointly issued by China Securities Association and other units 《 On Prevention NFT Initiatives related to financial risks 》( hereinafter referred to as 《 Initiative 》). Even though 《 Initiative 》 Affirmed the non homogenous token (NFT) As an important innovative application of blockchain Technology , Enriching China's digital economy model 、 Potential value in promoting the development of cultural and creative industries , But at the same time, he seriously called on all member units to resolutely curb NFT Financial securitization tendency , Strictly guard against the risks of illegal financial activities .

《 Initiative 》 It is also specifically proposed not to NFT Include securities in underlying Commodities 、 insurance 、 credit 、 Precious metals and other financial assets , Six propositions such as trading financial products in the same phase or issuing and financing tokens , All point to domestic NFT Illegal issuance of financial products in the field 、 Illegal financing 、 Investment fraud 、 Money laundering and other chaos , Intended to squeeze out the foam , Guide the blockchain industry to develop healthily . Combined with wechat recently 、 Alipay and other Internet platforms quickly banned many related businesses NFT A series of actions such as official account and small programs of digital collections , It's not hard to see. , Domestic right NFT The regulation of is being tightened day by day , Compliance requirements may also become more stringent .

China dominated by RMB NFT market , Although it is still in the initial exploratory stage , The practice is quite different from the development ideas of overseas markets , Try to weaken NFT Financial attributes of .

What's more? , As the blockchain field is not protected by Chinese laws at present , So once stolen , No one helped you find , So for us ordinary people , Just understand , When knowledge is popularized , That's it .

I happened to see that big ass tweeted about this a few days ago , Quoted here , Besides eating melons , And remind us of these IT Employees , There is no trivial matter in the production system , Be sure to take... Seriously .

Link to the original text 《 Eat the melon : value 2.2 One character of billion 》.

There is one abroad NFT( Digital art ) Project , Recently, it has launched thousands of products in public , To maximize profits , They used Dutch auctions .


What is a Dutch auction ? I set the price 3000 element , If you want to buy, just place an order , If the final unified transaction price is lower than 3000 element , For example 2500 element , Then the project party will return it to you 500 element .


This mechanism is actually encouraging users to go in early and loot , Because you won't lose money if you place an order early . As a result, the project sold well , It will be finished soon 3400 Million dollars in sales , The latest exchange rate is about RMB 2.2 One hundred million yuan .



as time goes on , Some big guys who are good at coding find that the contract written by the project party has logic problems , It may cause that the account receiving the payment cannot be withdrawn in the end . The core is the following line of code :

ba2f41fbd5ee86dfbed645bdc04bc2c4.png

This is this. refundprogress >= totalbids, This condition must be met to withdraw money .


Let me translate it in Chinese , This sentence is similar to the number of boys in school >= The total number of students in the school , It's impossible , Because as long as there is a girl in the school , This formula will not hold . In fact, the correct code should be <=, instead of >=, The direction of the symbol is reversed .


Because this condition cannot be met , So in this contract 3400 Ten thousand dollars (11539 My aunt ) I can't take it out again , Because it was probably for safety , Lock up the whole contract , It is forbidden to modify or upgrade , This is good , Guard yourself against thieves .

I heard that the mentality of the project party has collapsed ,3400 Ten thousand dollars in my pocket , But I can't take it out , If it were me, I would be crazy . In addition, users also exploded , It was originally agreed that the final refund would be made according to the transaction price , Now return an egg , But they are a little better , Because after all NFT I still bought .

Afterwards, someone roast , As a project worth tens of millions of dollars , At the very least, you should run the check on the test network BUG, It's so rash to put it directly into practice , It's a joke . This event once again shows the importance of yard farmers , Don't save money on yard farmers , They may not be able to do big things , But it can be bad .
