Calmecac 🤓💻

Calmecac is an educational platform that through the use of Web 3.0 technology requires the payment of a fee to access the courses we offer.

Inspiration

We are a Dapp that allows students to delegate capital for their studies, at the end of their course, they get 100% of their money back, making education much more accessible to certain social groups.

What it does

Facilitate access to education for students from all over Latin America without the need to lose their invested capital. Encourage the new economies proposed by Web 3.0 technology Become a Dapp work to help.

Challenges we ran into

According to UNESCO data, in the last three years 100 million students dropped out of school, and education is subject to the context of the countries resulting in an educational restlessness. With better educational offerings you have better job prospects, better salaries and therefore a better lifestyle.

With this in mind, we propose a capital delegation program where the student at no time loses his investment and can continue with his studies.

Accomplishments that we're proud of

We're proud to have created the real-time connection of the Dapp, creating the smart contracts of the platform and the base architecture of the project; front-end, back-end and the smart contracts development using Hardhat.

What we learned

We learned about Blockchain, Smart Contracts, Hardhat, Avalanche, ORM Sequelize, MariaDB, Express, AWS, Docker, React, React Native, Styled Components, Axios.

Intructions to run the projects

- yarn/npm i -> Install dependencies
- yarn/npm run android/ios -> Bundle for android or IOS
  yarn/npm run start -> Kick off the app for the platform previously specified.

By using the sequence of commands above, the project for android will be bundled and ready to work on.

• Backend:

cd server

# Create the .env file to start the project from the .env.example it is necessary to include an S3 bucket service
cp .env.example .env
# Install packages npm
npm i
# Crate BD en MariaDB and access phpmyadmin,for more information check config docker-compose-yml
docker-compose up .
# Create and initialize the database
npm run db:drop && npm run db:create && npm run migrate && npm run seed
# run project in development, check package.json for others scripts
npm run dev

#Note:If you don't have docker configured you can manually add the environment variables for mariadb

# POSTMAN
There is a file "Camecal.postman_collection.json" that can provisionally serve as a reference to use the api.
# Auth
This file is to work with POSTMAN, the authenticated is by Bearer Token
# Environments Variables
| VARIABLE     | ENVIRONMENT | VALUE                      |
| -----------  | ----------- | -------------------        |
| {{base_url}} | Development | http://localhost:3000      |
| {{token}}    | Development | GET IN RESPONSE AUTH LOGIN |

• Blockchain:

$ cd smartcontracts
$ npx hardhat test
$ npx hardhat run scripts/deployStaking.js --network fuji

To deploy the contracts on the Fuji testnet you need the RPC URL and the Private Key of the wallet to use:

FUJI_RPC_URL="FUJI_RPC_URL" // RPC URL FUJI Test Network
PRIVATE_KEY='PRIVATE_KEY' // your private key

Note:

Item memory item = marketplace.getItem(itemId);
//require( block.timestamp - item.createdAt > 4 weeks, "You must wait at least 4 weeks to distribute royalties" );
// To run the tests it is necessary to comment this validation and run them

To run the tests correctly, it is necessary to comment line 74 of the StakingCumulative.sol smart contract.
Because it has restrictions to every 4 weeks of staking time.

Staking

As a first version, Staking was added to receive commission as follows:

- creator profit: 1%.
- owner profit = 0.5%
- org profit = 0.467%
- referral 1 profit = 0.03%
- referral 2 profit = 0.003%

Features :
