Blockchain digital copyright protection system in PHP

With the advent of the digital age, digital copyright protection has become a difficult problem faced by many companies and individuals. In this area, blockchain technology has become a popular solution. As a popular server-side programming language, PHP's combination with blockchain has also attracted much attention. This article will introduce a simple blockchain digital copyright protection system implemented in PHP.

1. Introduction to Blockchain Technology
Blockchain is a distributed database composed of multiple blocks. Each block contains the hash value, transaction information and transaction information of the previous block. A random number, linked to each other, forms a chain that cannot be tampered with. The transaction information can be any form of data, such as digital currency, identity verification and other information. Due to the decentralized design, encryption algorithm and consensus mechanism of the blockchain, a transaction can be completed when and only when all participants reach a consensus, and the security and non-tamperability of the data are guaranteed.

2. Design of blockchain digital copyright protection system in PHP

1. System architecture
This system uses the architecture of PHP MySQL smart contract technology. Among them, PHP is responsible for processing interactive requests and business data logic, MySQL plays the role of data storage, and smart contract technology is used to implement copyright protection.

2. Smart Contract
In response to the special needs of the digital copyright protection system, we used the Solidity language to write smart contracts. The contract has the following characteristics:

• Copyright registration: stores copyright information in the blockchain.
• Copyright Trading: Allows copyright owners to sell their copyrights to other users.
• Copyright Protection: This contract will automatically execute the legal contract when the copyright is permanently transferred to protect the rights and interests of the copyright owner.

3. Copyright registration
When users create or purchase the copyright of a work, they need to provide information and supporting documents of the work (such as copyright certificate, etc.). This information is then written to the blockchain and contains hashes of work information, author information, and supporting documents.

4. Copyright trading
Users can freely trade their copyrights in the system. When a user sells his copyright, the smart contract will perform a series of operations on the blockchain including value transfer and copyright transfer.

5. Copyright protection
The smart contract of this system has a legal execution mechanism that can automatically execute the legal contracts required for copyright transactions to ensure legal and compliant transactions of copyright.

3. Summary
This article introduces a simple blockchain digital copyright protection system implemented in PHP. This system utilizes the unique decentralization, encryption and consensus mechanism technologies of blockchain to effectively protect digital copyright and protect the rights and interests of copyright owners. We believe that as more companies and individuals realize the advantages of blockchain technology, this digital copyright protection system will gradually become widely used.
