NFT records: are your NFTs secure?

When it comes to physical tools, where to "fix" them is very simple and straightforward. Prove the existence of physical objects (such as gold or silver) supported by the laws of physics. There is therefore no risk that your bodily substances will immediately disappear from the air. But for NFTs, things are now more difficult.

The nuances of NFT

In the case of normal mastery, the laws of physics can guarantee that the temperature at which a person will never go away. This is not important. However, the new membership in the digital space presents new challenges for the exchange of assets.Blockchain technology enables developers to create digital products at low cost.It also allows us to copy and paste text which is used when interacting with online content and opens up many new opportunities for members of digital devices.

NFTs are at the forefront of these innovations, and more than ever we need to study the nuances of investing in NFTs. New developments have brought good results, but we must beware of the unknown risk of investing in NFTs.

How important is data in NFT?

The core value of NFT is what it stands for.. Elements can be graphics, .eth names, etc. It is therefore true that the cost of TVN will disappear if the project disappears on the Internet. This phenomenon is not recent. Many NFT businesses are sensitive to these risks. This section is intended to provide you with everything you need to know about NFT Information Security.

For NFT, it's not the end of the world!

One million NFT million is in danger of losing its value, so we need to raise awareness. This does not mean that this applies to all NFTs, but understanding the circumstances that drive the price of most NFTs down will help you determine the highest risk.

This situation is often overlooked, but it is important to point out the risks. But no one can hurt you if you are aware of this situation.This is the charm of blockchain. It is open, transparent and the published data is not wrong.

NFT data retention method

Each project uses the most suitable and controllable method for storing NFT data. There are two types of data collection.

● Centralization

● Decentralization

"Wait, I think we are talking about blockchain, but all without permission or distribution." It depends on the situation, so let's take a closer look at this.

How decentralized NFT?

Blockchain is a distributed list that is supported by cryptography and opens the door to the availability of digital assets. Blockchain and digital assets are decentralized by default, but the situation for NFTs is slightly different than for ERC20 tokens.

At the heart of NFTs are blockchain smart contracts such as E **.This smart NFT token will generate (also called casting) ERC721 tokens. Each token is assigned a URI (Uniform Resource Identifier) ​​symbol. The URI is equivalent to the NFT identification number. Everything we've talked about so far has happened on the distribution blockchain. From this perspective, NFT data can be divided into two categories.

The URI of the token is equivalent to the address. This address is unique to each NFT and indicates where the NFT data is stored. Just as a home address points to a city address, the NFT URI points to an Internet address.

Blockchain does not require smart entrepreneurs to point the token URI to the affected area. Thus, it is up to the developer to determine where the NFT data is stored. The file contains a name, an image, and a few attributes.

in conclusion,Although NFTs are decentralized by default, the token URI can point to the base database. This means that NFTs still present some risk in the environment.

data security

Typically, developers determine whether their NFT file points to the database or the distribution file. Speaking of which, NFT metadata can be stored on the blockchain itself,Such NFTs are called chain NFTs.

Campaigns like Squiggly have used this approach. The NFT token URI is stored in an intermediate application programming interface (API), but the images are also hard-coded on the chain for backup purposes.

This means that Squiggly's NFT images are not sharp and stable.

However, there is more to distributed data storage than the expensive way to store data directly on the blockchain.

Developers of programs like Bored Apes have undergone a cultural shift. The problems associated with the creation of data transmission over the network are not new. Even before E **, people thought about it. Some solutions are already available, such as FileCoin technology and IPFS.The most popular way is to use IPFS technology.

As you can see, we have provided the metadata unchanged for this NFT even without the metadata in the string. So how can we not change?It is a distributed network because the data is stored in IPFS.

IPFS stands for Interplanetary File System. The agreement aims to create a peer-to-peer network for information storage. If the BTC values ​​are similar, the IPFS is the same for the data. Each file in IPFS has a unique address (like the token URI in NFT). This unique address is distributed throughout the network. Once the image is stored on IPFS, it cannot be edited and will remain on until the network is shut down. Therefore, it is not affected by centralized attacks and corrosion.

This solution is generally applied to situations in graphics and NFT objects.This is because metadata is not dynamic and does not need to be modified.However, this solution cannot be extended to traditional digital games like Axie.

If you look at Axie, you will see that unlike the first two, there are no metadata tags that can be edited. This means that NFTs are vulnerable to moderate risk and cannot withstand censorship.

Let's see why this happened:

If you've played video games, you know the characters are strong. This means that you can adapt, lose battles, etc. The high quality of NFT gaming tools makes it almost impossible for developers to store data in the distribution. That's why Axie needs to rely on the central database to make sure that the role change doesn't cost players too much. Consider the need to pay for every action in a game. It will definitely ruin the game. This is why the developers at Axie have decided to keep their metadata in the data center. You can prove this by using an Etherscan tool and checking Axie's token URI.

Distributed data storage solution

The blockchain ecosystem has a new and stronger culture, with all the technological know-how of new solutions.Solutions like IPFS have stood the test of time. However, as we have seen in sports heritage, current solutions still have some limitations. NFT is still very technologically advanced technology and this is just the start of a long journey. Deserves to be the mother of invention. As the demand for NFT continues to grow, there are also newer and more innovative solutions available. One of these new solutions isCrust network.

Crust networkIt is essentially a card-based blockchain, protocol and storage repository design supported by IPFS for the Web3.0 ecosystem. It aims to create a climate ecosystem that values ​​privacy and property information.

The NFT trading platform integrates Crust and IPFS technology to provide NFT metadata. The solution can be divided into 5 steps.

1. Import NFT files into IPFS.

2. Collect and share NFT data on the Crust Network.

3. Monitor the storage status of NFT files on Crust Network.

4. Users access NFT data through the NFT trading platform.

5. If you re-order your order within 6 months, the expiration date of the NFT file will be extended.

Recently, Crust also announced Crust Files, a low cost Web3 storage tool. Download files with one click and save for free. The official version of Crust Files is coming soon and will be priced at $ 50,000,000.
