How to use

Connecting peers

1. Connect two or more peers in seperate terminal sessions.

First, peer 1 (npm run peer1):

./node_modules/.bin/cross-env PEER_PORT=6001 HTTP_PORT=3001 node index.js

and peer 2 or (npm run peer2):

./node_modules/.bin/cross-env PEER_PORT=6002 HTTP_PORT=3002 PEERS=6001 node index.js

Mine the Blockchain

Use curl below to simply execute or just run (npm run mine)

curl --data '{"content" : "Add some data here"}' -H "Content-Type: application/json" http://localhost:3001/mine

or you can use Postman to execute POST requests and mine for blocks.

Unit Tests

Run the unit tests by executing the following command:

npm run test

Tests will run using AVA and validate the blockchain technology code to see if it's broken through Q&A scenarios.

Additionally, you can run npm run lint to check to see if the code is ESLint compliant.
