# Learn Blockchain

This is a project to learn about blockchain technology and how it can be used to create a blockchain.

## What is a blockchain?

Blockchain is a series of records, called blocks, stored in a public ledger. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.

## Development

To clone and setup the project, run the following command:

```

$ git clone https://github.com/eavelasquez/learn-blockchain.git

$ cd learn-blockchain

$ yarn install

```

To run the project, run the following command:

```

$ yarn start:instance 1 # Starts a server instances on port 3000 and 5000 (default)

$ yarn start:instance 2 # Starts a server instances on port 3001 and 5001

```

To test the project, run the following command:

```

$ yarn test

```

## Next Steps

1. Add a new endpoints `/wallet`

  1. Add a new endpoint `/wallet/create`

  1. Add a new endpoint `/wallet/:address/balance`

  1. Add a new endpoint `/wallet/:address/transactions`

1. Include a fee in the transaction. 


  NOTE: The fee is the amount of coins that are sent to the miner as a reward.

1. A client application that can create, send, and receive coins, etc.

1. Improve the mining logic so that it selects a maximum number of transactions according to the fees.
