[NFT Processing (Metadata verification method through NFT)]
This is a continuation of the previous content.
ERC-1155 enables a mixed transaction of FT (ERC-20 token item), which is a replaceable item, and NFT (ERC-721 token item), which is a non-replaceable item. A large amount of redundant data is accumulated in the ERC-20 token and the ERC-721 token, and unnecessary codes remain due to the property of the blockchain that forgery is impossible. For this reason, large-scale storage space and processing capacity are required, and there is a problem of power consumption, so ERC-1155 appeared as a solution to this problem.
The fact that mixed transactions are possible means that NFTs with different data can be gathered in one place to collect information. In other words, like off-chain servers, in the on-chain, nodes can be distinguished from each other through NFTs, and it is possible to connect to the server.
For example, suppose there are a total of 4 NFTs with information of 1/3/5 and 2/4/6, 7/8/9 and 10. These four NFTs enter one specific smart contract pool deployed to synthesize information from 1 to 10 and become one, and are reborn as NFTs with all information from 1 to 10.
Another characteristic of the metadata verification method through NFT synthesis is that it is possible to check and verify whether the NFT owned by the owner is a legitimate NFT. As in the above case, if there are 4 NFTs, if the NFT containing the information 10 contains 11 instead of 10, the 4 NFTs in the smart contract pool do not sequentially indicate 1 to 10. It will display the information 11 after 1 to 9. This not only goes against the purpose of the smart contract function, but also reveals that the NFT owned by the owner is not a legitimate NFT. Through this, it is possible to prevent the misuse of NFTs owned by hackers or illegal copyists, and at the same time determine the authenticity of the original content NFTs. If you understand by referring to the example above, you can check whether the NFT created and certificated by the content provider is correct and what information it contains. The VIW NFT verification protocol embodies and systematizes a complete and stable NFT issuance, transaction, and verification system through various procedures and processes.
