Secrets Unlock .rev*Files on Ethereum

Ethereum, decentralized intellectual contracts and decentralized programs (DAPPS) platform, use different file formats for data storage and transfer. One of these formats is .rev, which means “cancellation” and used to store information about the Nonal ERC-721 (NFT) cancellation. In this article, we dive into the .rev world and examine what they are there.

.rev * File structure

Typical .rev file* consists of an outdoor with [F9B4D9 + 32byte Numerized + Kinklioma Used Proproconal Data] for each element. Here’s the collapse of what it may seem:

`C

[F9beb4d9, 32by_number, var_raw_data]

The first part, F9BEB4D9, is a magic number identifying the file type. It is not used directly in data, but is a unique identifier.

The second field, “32byte_number”, is an optional seal of the time when the cancellation was recorded. This can be useful for audit purposes or observe the history of reviations.

A variable raw data

In the third field, var_raw_data, there is variable starting data that may include, for example, metadata:

• Hasse: Unique NFT Identifier

• Metadata: Additional information about NFT (eg creator, description)

• Transaction_hash: bag operations that created or updated NFT

These non -processed data variables are not strictly needed and can be missed if necessary. However, it should be noted that missing this area can cause inconsistent recall records.

More information

It is worth noting that. They contain a specific set of rules for the creation and management of these records.

Conclusion

Finally, .rev Ethereum files provide a convenient way to store and provide information about the NFT. Although the structure is simple, it is necessary to understand the context that uses these files. If you are developing a program that interacts with the ERC-721 NFS or requires access to this data, familiar with the .REV file format, you can help your development process more efficiently.

CODE EXAMPLE

Here is a simplified example of how the file .rev* rust may seem:

`Rūdys

Use et_types :: {hash, U256};

The structure absolutely {

Time Seal: U64,

Bags: bags,

Metadata: [u8; 1024], // Variable starting data (optional)

}

Removal of implant {

FN NEW (Timesstamp: U64, bags: bags) -> self {

Cancel {time tag, bag}

}

}

`

Remember that this is a very simplified example and actual implementation may vary depending on the specific requirements for your project.
