Blockchain

Blockchain use for cryptocurrency transactions. Uses Proof of work for consensus.

Having in mind that blockchain runs in a distributed network,
until I build a GUI for this project you’ll have ot use:

• Terminals, commandPromnt, etc.
  • For windows users I recommend GitBash

• PostMan(app/web) versions

  • this is to make requests.

  Local environment testing.

  Open at least to terminals(GitBash) in project directory and PostMan(app or browser).

  1. In one of the terminals run npm run dev.

  This should start a Peer-to-peer Networkk in P2P_PORT=5001.
  The application should be running in the HTTP_PORT= 3001

  Lets reserve the [5002-5999] ports for P2P connections and
  the [3002-3999] ports for app connections.

  RUN COMMANDS

  There are 3 parameters when running this application.
  After running the app for the first time. like instructed earlier,
  to connect with another terminal you must concider 3 things:

  1. The HTTP_PORT you want to connect to.
     • HTTP_PORT=[3002-3999]
  2. The P2P_PORT.
     • P2P_PORT=[5002-5999]

  3. And the already connected PEERS

     • PEERS=ws://localhost:3001
     • for multiple peers separate with (,).
     • PEERS=ws://localhost:5001, ws://localhost:5002, …, …

     Full Example:
     HTTP_PORT=[3002-3999] P2P_PORT=[5002-5999] PEERS=ws://localhost:5001, ws://localhost:5002 npm run dev

     This command is to at least have to “computers” running the blockchain.
