About Machu Picchu

General Presentation

Machu Picchu is the umbrella name of a collaborative open source initiative. It aims to use the Ethereum blockchain (or Celo) to share “Data as a Public Service” among all the humanitarian organisations that provide support and benefits to the persons-in-need. These persons remain owners of their data and receive a micro-fee from every entity that retrieves this data. Like when you give your data to the GAFA to obtain map guidance, news, entertainment suggestions, taxi services etc. But here the data are accessible to all, including startups. The business model is explained here in Medium and also explained here on YouTube.

The need to share data among humanitarians is recognized. The addressable market is huge: Cash and Voucher Assistance programs alone totalled $5.6bn in 2019, quote the joint Danish Red Cross/Mercy Corp/HiveOnLine report of November 2020. And wait, there are more aid and relief programs than that: risk sharing, credit rating, gender equality, health practices, education, mother and child care, civil governance etc.

The ultimate achievement is to make an inclusive DEX where the persons in need may swap the humanitarian tokens that they received from different organisations (for example Red Cross, UNICEF, World Food Program, etc.) and obtain a significant bundle of a single tokens that can be redeemed against medicaments, schoolbooks, agriculture tools etc.

Business Model

Vision of Technical Stack

A vision of the complete Technical Stack that can be used for Machu Picchu is, in April 2021 and if we have 2-3 M$ immediately available :-)

Pepito

Pepito is the entry of Machu Picchu to the ETH Denver 2021 Buidlathon. It is the demonstrator of how the personal data of the person-in-need can be stored. To make the blockchain more friendly to decision makers of helper organisations, instead of a boring user KYC data screen, we generate a disguise and store it. It constitutes the "Trust Engine" at the bottom left of the Machu Picchu Technical Stack.

Beyond Pepito…

Because of the technical background of Vu Tien Khang as Data Science, Earth Observation, on top of Space and Telecoms, our vision is to add collaborative data analysis tools, Geographical Information System mapping tools, and Earth Observation tools to monitor crops and natural disasters. This will be started once Pepito has 10'000-50'000 persons to manage, provided funding is available.

Objectives for the ETH Denver 2021 Buidlathon

• Port Pepito to Celo
• Make Pepito store on IPFS its table of Disguise addresses
• Make each PepitoDisguise store its data on Textile or OrbitDB
• Implement the frontend dialogue to change the features of a PepitoDisguise and store it back
• Use the Celo Valora mobile wallet
• Implement the frontend dialogue on mobile

Instructions to run the public frontend, backend already deployed

Tested on Chrome, Mozilla Firefox and Safari.

Instructions to install backend and run locally the front end

Pre-requesites: NodeJS & Truffle

1. Fork this repo to your repo and clone it, or clone directly: run git clone https://github.com/Machu-Pichu/ETHDenver_2021
2. cd to ETHDenver_2021/Pepito and install the dependencies: run npm install
3. cd to ETHDenver_2021/Pepito/src and create your own CELO testnet crypto account to pay the blockchain fees of the demo: run node createAccount.js
4. ... this creates a new CELO test account and displays the account address on the console. Copy this account adddress
5. In the same src folder, in MakePepito.js, remove the line 36 that hard codes the address, to use rather the one stored in file .secret
6. Go to Alfajores test faucet and fund the account by pasting the address you just copied, answer the CAPTCHA and click on "Get Started": https://celo.org/developers/faucet
7. Deploy the smart contracts (migrate the project) on Alfajores test network: cd to the folder ETHDenver_2021/Pepito and run truffle migrate --network alfajores --reset
8. In the same folder, launch the React frontend: run npm run start
9. your browser will open a new tab at address http://localhost:3000 and display the frontend

Voila!
