Project Overview :page_facing_up:

Overview

This Proposal is based on https://github.com/w3f/Grants-Program/blob/master/rfps/scale-codec-comparator.md. To date, there are more than 9 published implementations of the SCALE Codec. Since each is implemented by a different team & the reference implementation still introduces small fixes, it would be beneficial to compile a table of feature-completeness. This would provide (some) assurance that the implementation in a given language is safe & sound to use.

I have already developed https://github.com/gmajor-encrypt/php-scale-codec && https://github.com/gmajor-encrypt/php-substrate-api in the previous grant.

Project Details

1. Providing an FFI to Rust's reference implementation
2. Tested with rust's FFI along with the scale lib https://docs.substrate.io/reference/scale-codec/
3. Passing the test will release the scale code badge of the GitHub action
4. Add Github action ci automatically test if these libs are updated

Ecosystem Fit

Help developers choose suitable the scale code package in the ecosystem to avoid unknown errors
