If you follow the trend of the crypto world, maybe you are already familiar with the name NFT or Non Fungible Token.
NFTs are changing the way people buy and sell digital collectibles. The NFT wave also brings new opportunities for decentralized storage.
This development did not go unnoticed by Crust as a project with decentralized storage services. Crust will take advantage of the rapid development of the NFT market to further deepen exploration and cooperation in the NFT field.
Crust also provides services for storing NFTs, because generally NFT assets such as artwork and collections often require multimedia files such as images and videos to be presented.
These files are relatively expensive to store on the blockchain, therefore, they must be stored off the chain.
How to Save Via Off Chain
If you want to keep the metadata off-chain, there are two options:
Centralized Server
The simplest metadata storage solution is to store it on a centralized server or cloud storage solution such as AWS.
However, there is a drawback to this centralized storage that the developer can change the metadata randomly, if the project is offline the metadata can be destroyed.
To solve this problem, there are several services (including OpenSea) that currently cache metadata on their own servers to ensure that even if the original hosting solution fails, they can still effectively provide metadata to users.
IPFS
IPFS is a peer-to-peer file storage system that allows content to be stored between computers, so that files can be backed up to several different nodes.
This ensures that the metadata is immutable as it is handled uniquely by the file hash, and as long as one node is willing to host the data, the data will persist over time and may not be retrieved due to project termination.
Now, developers can simplify this process for efficient storage via the open Crust Storage Network.
NFT Storage in Crust
The NFT trading platform can meet NFT file storage requirements by integrating Crust and IPFS. The solution is divided into the following four steps
1. The NFT trading platform imports NFT files into IPFS;
2. The NFT trading platform stores and distributes NFT files over the Crust network;
3. The NFT trading platform monitors the storage status of NFT files on the Crust network;
4. Users access NFT files via the NFT trading platform.
NFT Scale Products
Most recently, Crust joined the PolkaPets NFT series that launched on Bondly, and it sold out quickly.
NFT Scale Value
Going forward, Crust will support more utilities for NFT holders, such as obtaining VIP benefits and immediate information about upcoming achievements, priority for community activities, and enjoying the benefits of the Crust ecosystem application, marking VIP user status, etc.
