PHP Version of SCALE Codec
This Request for Proposals is closed, meaning we are not looking for any more proposals on this topic at the moment.
Project Description 📄
The SCALE codec is the de-factor encoding method in Substrate-based chains. It is necessary for APIs to be able to communicate with a running node. There are several implementations already available in the wild, all listed here. This proposal is for a team to build a PHP version.
The deliverable should be a standalone SCALE codec package, hosted on Packagist. It can (but does not have to) depend on existing Base58 packages already present on Packagist.org.
The package can also be delivered as a companion PHP extension but the extension should be exclusively a performance upgrade to the existing package. In other words, the Packagist-installable library should work on its own, but can be improved by also downloading the (optional) PHP extension. If the applicant decides to also create the extension, they should submit it as a separate milestone.
