About this dApp

• Ethereum dApp built on Solidity + React.
• Project developed by Diego Gonzalez (@ Enxendra/Docuten) for ConsenSys Bootcamp 2019 (Twitter: @dgrmunch | Web: xmunch.com)
• To be used for distributed proof-of-existence and proof-of-life experiments (using document hashes + ipfs hashes).

Video tutorials

To run your own

• Check this video to see how to run your own instance of the dApp:

• I have published also some instructions below, just in case you want to go deeper or if something in the video is not clear enough.

How to use a currently deployed instance

Use directly the dApp:

• Access https://dgrmunch.github.io/docuten-blockchain-proof-dapp
• Connect Metamask to Ropsten

Use etherscan and interact directly with the proxy contract

• More info about the addresses + ABIs for deployed smart contracts in the file deployed_addresses.txt

To run it in your own server

Installation

npm install
npm install truffle-hdwallet-provider
npm install --save gh-pages

Running the dApp

On one shell

Run:

truffle migrate --network ropsten

or

truffle migrate --reset (for local test)

This will deploy the smart contracts.

On another shell

cd client
npm run start

This will run a node dApp. Open http://localhost:3000 to view it in the browser.

You will need Metamask in your browser to make it work

Deploying the dApp in Github pages

truffle migrate --reset --network ropsten
npm run deploy

By default, it will be deployed here: https://dgrmunch.github.io/docuten-blockchain-proof-dapp/ Update the configuration in truffle-config.js in order to adapt it to your needs.

Test the smart contracts

truffle test

How to get the ABI of the contract to use in MyEtherWallet?

• In deployed_address.txt (updated)
• In the truffle develop shell, typing:

const fs = require('fs');
const contract = JSON.parse(fs.readFileSync('client/src/contracts/ProofOfLifeProxy.json', 'utf8'));
console.log(JSON.stringify(contract.abi));
