Proof of concept of a hybrid real-estate app with blockchain and Ethereum smart contracts.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
You need Node.js >= 8.0.0.
Install Truffle
npm install -g truffle
Install Ganache or ganache-cli to run local Ethereum blockchain.
npm install -g ganache-cli
Clone the repo
git clone https://github.com/kopylash/blockchain-real-estate-v1.git
Install dependencies
npm install
We use Sequelize for database manipulation. Project is preconfigured to use PostgreSQL. To connect to the database setup environmental variable DATABASE_URL in format:
DATABASE_URL = "postgres://<user>:<password>@<host>:<port>/<database_name>"
IMPORTANT: Postgres should have POSTGIS extension installed. And you should enable it in your database by running:
CREATE EXTENSION POSTGIS;Database is automatically synchronized with Models definition.
Before starting the app start local ethereum blockchain with Ganache. For this either open Ganache app or run:
npm run start:eth
NOTE: we use next mnemonic for development purposes, some configs are predefined.
candy maple cake sugar pudding cream honey rich smooth crumble sweet treat
Compile smart contracts.
cd ethereum/
truffle compile
Deploy the contracts onto your network of choice (default "development"). Check Truffle docs for details.
truffle migrate
Then run server with
npm start
The complete API reference is published to Postman. You can import it and use for testing.
