Welcome to greyMeta

GreyMeta is a decentralized E-learning hub designed to allow the freedom of learning and exchange of flashcard collections as digital assets on tezos chain. The experimental project started during the Metamorphosis 🐛🦋 Hack 2022.

Built with

NextJS - Client Framework
Chakra UI - Styling
Web3Auth - User Friendly Authentication
jLigo - Smart Contract
Taquito - Smart Contract interaction and signature
IPFS and Infura - Decentralized Storage

Features

Digital Assets - Study with flashcards in your catalog; cards puplished by others or simply create yours
Defi - Earn Tez tokens as external views/traffic on your published collection increases
Decentralized Storage - Pin asset metadata securly on IPFS on serverside and control signatures allowed to modify data

Demo

Testing Frontend

Run yarn install and yarn dev and you're ready to go!
To setup a web3auth account, refer to this docs

Smart Contract Overview

Contract address : KT1SW6BtUxQnHP4RaSu2B767WWPYGKCeWh8F


type collection_supply = {
    owner : address,
    views : int, 
    info : string,   
};

type action =
| ["Publish", collection_supply]
| ["Buy", int]


type storage = {
   collections :  big_map<int, collection_supply>,
   next_id: int,
   };

Updating the views of each collection

  let updated_collections: big_map<int, collection_supply> =  Big_map.update (parameter, Some(collection_kind_), storage.collections);

Rewarding the author for each external view

  let receiver : contract<unit> =
    match ((Tezos.get_contract_opt (owner_address) as option<contract<unit>>), {
      Some: (contract : contract<unit>) => contract,
      None: () => (failwith ("Not a contract") as contract<unit>)
  });

 let payoutOperation : operation = Tezos.transaction (unit, Tezos.get_amount (), receiver);

Testing and Deploying

Compile Contract written in Ligo, dry run and deploy online
