After Decentralized NFTs: Centralized Decentralized Work

As the Lunar New Year approaches, investors seem more concerned about the prospects for capital investment in 2022.

As the Fed's monetary policy shifted from dove to eagle, the US stock market began to recover from all-time highs, the cryptocurrency market also fell, and Bitcoin fell below $35,000.

The low level of NFTs affected by the violence in the community, which began in earnest a week ago, has dropped 81% from its peak. However, recently, blockchain applications such as NFT, DAO, DEFi, and Web3 are rapidly breaking out of the loop and gaining public attention.

All operating systems offer their own products under the Web3 banner, called "commercial development support". During this time, some engineers and cryptographers discovered that some things were wrong.

OpenSea is not too “decentralized”.

On January 9, OpenSea experienced a service crash, leading users to complain that web pages weren't opening or loading slowly. Netizens joked that it was not a decentralized platform and called it Mr. Close.

Last month, OpenSea user Todd Kramer took to social media and 16 Bored Apes NFTs worth $2.2 million were stolen. Help freeze all stolen NFTs.

The news has sparked criticism and concern from all sides, claiming that OpenSea can abandon NFTs, which does not pose a threat to cryptocurrency attacks. Netizens asked if OpenSea was really affected."True membership, no one can interfere."

The dark truth behind NFTs

Tech Lead, an internet expert who has worked for Google and Facebook, released a special video to shed light on the truth behind NFTs. “OpenSea is 100% middle ground,” he said.

In the video, he announced a reddit called “How to get all NFT from Ethereum address”.Can I see all available NFTs from the Ethereum ERC-721 address? The answer is no.

Some netizens hear that it is a flaw in Ethereum, and the wallet address that a particular NFT can see can only be seen by looking at the Ethereum contract, but he cannot see the image of NFT which is NFT inside. wallet. If you want to know where the NFT is, just scan the entire NFT contract on site and also enter the data on the OpenSea root platform to see what the photos really look like. .

Professionals and executives can view NFT file information directly.Some NFTs are not stored on the Ethereum chain, but in centralized storage like Google Cloud. "Until now, there was no real NFT wallet."

love love,sivWhat users won't have is the NFT image of the blockchain, but the text on the blockchain. The text points to the site in the middle, and the site in the middle is where the real photos are stored.The file is shown below. The last address of the NFT sentence points to the OpenSea database. When OpenSea crashes, NFT displays a broken image.

He thinks OpenSea protects user data. Because we don't want users to move their NFTs to another platform, and we just don't tell them where the NFTs may be. It then opens the API at the NFT address, which requires detailed information from the NFT. However, it was empty and without papers.

However, not all NFT files are empty. Tech Lead as an example to measure that NFT has distribution.

Ruisi Finance doctors used their method to give us an example. First let's take Bored Bunny #1210 as an example. This NFS is stored on the IPFS distribution point.

If you ask for its Ethereum address in a browser block and enter the number 1210 in the token URI, you will see an IPFS address appear. IPFS is a decentralized storage system, which is a standard decentralized configuration when images are contained in IPFS.

If you continue to open this IPFS file, you will see that the first file in Bored Bunny #1210 describes the properties of the image. The rabbit's skin is green, the back is red, and the teeth are clean. No tattoos.

In the second, the NFT file links to the main website. Mutant Ape Yacht Club work #11318 as an example.

You can view it in the browser block and the address that appears is .com which is different from the current IPFS partition address. The project party collected photos from the official project website borapeyachtclub.com. Then, if the legitimate project part website goes down, there is a very high probability that this NFT series will have problems.

There is also a third event, like PHANTA BEAR, which Jae-beom Joo is participating in. Special data is not visible when looking at the terms of the contract, and it is not possible to confirm where the image is, and analysis is not possible.

Web3 app draws skepticism from cryptographers

Another expert found more problems. A well-known author named Moxie mentioned in the "My First Enjoyment of Web3" ad, writing that by consensus, I don't believe in some use of Web3 yet. In this article, he introduced the "fig page" of some of the current pseudo-Web3 applications, and even received a response from the Ethereum developer.

From his point of view, Web3 is a vague term and it is difficult to define what Web3 is. But in general, Web1 seems decentralized, Web2 centralizes everything on the platform, and Web3 decentralizes more.Web3 requires a multitude of Web2 applications, but requires distribution.

It is well known that mid-platforms appeared because people don't want to run their own servers and the self-running process is slower than root platforms. But in Web3 it's said differently.He decided to create some dApps and create NFT for easy understanding.

It creates and transmits "identical" charts to NFT trading platforms OpenSea and Rarible respectively., and what users see during a purchase varies from platform to platform, and what they see in their cryptocurrency wallet is an image of a poop emoji.Why do the "same" images appear in three different ways?

Why,NFTs generally do not store this information on-chain. The price is too high for most NFT images.Moxie discovered that the URL link after almost all NFTs-NFT artworks sold for millions or tens of millions of dollars - was provided for posting the content.No encryption technology is used, but some virtual machines have been introduced.

It means,As long as someone buys or hacks this virtual machine, the images, names, descriptions and other information provided by this NFT may be changed.This is because the inconsistency of the NFT doesn't tell what the picture is or what the "real" picture is.

Virtual machines can display different images for different IP addresses and different names, so you can customize the "five" images created by Moxie as you wish.

Shortly after this experience, OpenSea lifted the non-compliance of Moxie, but they carefully checked all the rules of this NFT trading site and no one said that NFT tokens are not present and can be changed depending on the IP.

Moxie's article would be invalid if OpenSea were accused of harassing its users. After all, the entire cryptocurrency cycle has accused OpenSea of ​​"Web 2 disguised as Web3". Instead of using the decentralized DAO method sending airdrops, we want to go public at the IPO.

Another surprise was that after OpenSea removed Moxie's work, its NFT functionality also disappeared from the MetaMask crypto wallet.However, this is due to the fact that Moxie's NFT transactions have been “monetized” (i.e. registered with the Ethereum network) on the Ethereum network, and these cannot be deleted. Logically, this shouldn't happen in a Web3 application.

Moxie explained that crypto wallets such as MetaMask, Rainbow, etc. are "non-administrators" (keys are stored by the user). A wallet like MetaMask should perform simple tasks such as displaying balances, recent changes, and NFTs, as well as more complex tasks such as setting up a business and engaging with other smart contracts.

In fact, MetaMask should interact with the blockchain, but the blockchain was designed in such a way that users like MetaMask cannot interact with it. MetaMask therefore does this by calling APIs for our company's integration into the site, just like its own dApp (blockchain application).

Thus, the disappearance of NFTs published by the author of MetaMask can be seen as a major problem for the current Web 3 industry, which is the inability to communicate with dApps (blockchain applications) declared as classification. Instead, it uses APIs from several major blockchain companies.

And the API link is not guaranteed in any way. I don't even sign it, if the user later proves he is lying. MetaMask doesn't really do anything, it just looks at the data provided by the APIs in the middle.

Moxie thinks the problem with applying MetaMask or Web3 is the fraud that runs through the history of internet development.If technological processes were used as much as possible by humans, it would lead to the emergence of root platforms. Because only the latter makes the product easy to use and easy to use by continuing to work for more users. this.

Although you can use your PC as an Ethereum node (which is not very practical for modern users currently), you can switch from the Ethereum wallet, but beyond the tastes. By working hard on the blockchain, regular users will find Coinbase. , OpenSea and I would choose products from a big company like MetaMask. The rise of these companies is actually the creation of new facilities.

Moxie's post went viral on Twitter, prompting Ethereum founder Vitalik (Vitalik) to answer her questions.

Buterin argues that what Moxie calls the popular "centralized" blockchain application does not itself use cryptographic technology.The simple blockchain is far beyond the public. He thinks this is mainly because people in the industry want to create apps that can be used by many people. In this process, centralization is the fastest way.

Buterin also claims that Web3 is still in its infancy. Earnings are rare before 2018, and after 2018 there is plenty of money, but not enough time to transfer most of the money to software users. However, in the future, the different spectrum for Web3, from centralized (platform) to decentralized (private server) will be fulfilled.

However, the words of God V did not fully respond to Moxi's amazing words even early on,Is this an appropriate way to promote decentralization in the form of centralization?After all, before reading this article, I think everyone has used purely blockchain applications.

Currently, the application of content distributors such as NFT or DAO, DEFi and Web3 is very hot. OpenSea, MetaMask, etc. Broadcast exchanges and Dapps (decision-making app) as "born with a difference". They raised the Web3 banner and saw an increase in users and features.

But when they advertise "blockchain technology" and the "app industry" like Web3, do they have to tell their users the truth? At the very least, users who spend hundreds, thousands, or millions of dollars on expensive NFTs need to be sure they will buy.
