About Blockchain

Hi,

You can easily develop blockchain application on PHP, like on any other language. Of course, you should count of few limitations: first, only few blockchains have available PHP SDK (or REST API) and other tooling to leverage development and testing using PHP. Reason for that is nature of blockchain, that is similar to lower level protocols (think about it like TCP/IP for networking, or IMAP/POP3 for emails) then PHP that is designed for web. S

So you might be more efficient by implementing blockchain-facing part of your app using more appropriate techstack like Go, Node.js or Java, and if there will be client-facing part of your project that extends to the internet you can do it in PHP.

And you cannot edit form data in blockchain by default Blockchain is not a conventional database. Also, in 9 cases out of 10 you do not need blockchain and probably your customer has very little clue about its usage patterns.
