[DMP 2024]: Use Once Statements Pallet

NiranjanAP commented 4 months ago

Ticket Contents

Description

Use ONCE with 'statement' can be more clearly explained with an usecase of event ticket which is 'use once'. It can be true with flight tickets, museum tickets, event tickets etc.

So, think of a usecase, where any 'approved' applications can look at a statement (VC, PDF file, image etc), and if found valid, this app should be having a method to update the statement's status to 'Consumed' (or something similar).

This way, the validity of tickets verification is logged on chain.

Goals

[ ] Create a new Pallet called UseOnce and implement the requirements mentioned in the description
[ ] Add unit test cases
[ ] SDK implementation that calls the corresponding methods in CORD pallet
[ ] Build a demo script to demonstrate the usecase

Expected Outcome

A new pallet call UseOnce that can make sure that an entity is used only once

Acceptance Criteria

A Demo script that demonstrates the right behaviour

Implementation Details

Need RUST and Substrate knowledge as a pre requisite for implementing the pallet, Typescript to SDK and a demo script Go through the other pallets for reference and understand the implementation

Hey @NiranjanAP @amarts, i would like to work for this project as part of dmp 2024.

NiranjanAP commented 2 months ago

Sure, go ahead

smitjiwani commented 2 months ago

How should I proceed with contributions @NiranjanAP. I would really appreciate your guidance 😊.

NiranjanAP commented 2 months ago

As a prerequisite please go through

RUST programming language - https://www.rust-lang.org/
Learn substrate basics and how to create a pallet - https://docs.substrate.io/tutorials/ Once you are able to create a sample pallet, you can create a pallet with requirements specific to 'Use Once Statements'

Keep in touch with vatsa@dhiway.com he'll help with if you get stuck somewhere.

Also, C4GT team might have some process to follow before you jump into coding, please work with Abhishek and Vanshika

@NiranjanAP @amarts Just wanted to check something about UseOnce. So, in the new pallet UseOnce approved applications which could be software applications or services will have the capability to inspect/look at the verified credentials or other specific files. If these entities are determined to be valid through cryptographic verification or any other validation mechanism implemented within the system, the UseOnce feature will enable these applications to update the status to consumed. Am I correct in understanding the description? I wanted to ensure clarity before proceeding further. Thank you!
