This is just a demo project just for concept purposes. Please don't use this in production. Reasons not to use PHP for blockchain development or in production:
Security: Blockchain systems require a high level of security because they deal with valuable assets and transactions. PHP, while it can be secure when used correctly, has had security vulnerabilities in the past. Languages like C++ and Rust have better memory management features that can help prevent common vulnerabilities like buffer overflows.
Community and Ecosystem: Blockchain development relies heavily on available libraries, tools, and an active community for support. PHP has a limited ecosystem for blockchain development compared to languages like Python, JavaScript, or Solidity (Ethereum's smart contract language).
Concurrency: Many blockchain systems require high levels of concurrency and parallelism. PHP's architecture is typically designed around a request-response model, which may not be well-suited for handling the concurrent nature of blockchain networks.
Blockchain-specific Libraries: Most blockchain networks have their own specific libraries and APIs for development. While there might be PHP libraries for blockchain integration, they are not as prevalent or well-maintained as libraries in other languages.
