✅ Testing

To test the blockchain, you can use Postman or any other API testing tool.

1. Mine a new block

Mine new block by requesting the endpoint http://localhost:1337/blockchain/mine with a POST request.

2. Get the blockchain

Get the blockchain by requesting the endpoint http://localhost:1337/blockchain with a GET request.

3. Get Block by index

Get a block by index by requesting the endpoint http://localhost:1337/blockchain/{index} with a GET request.

4. Add a new transaction

Add a new transaction by requesting the endpoint http://localhost:1337/blockchain/transaction with a POST request.

You may need to specify the 'content-type' header as 'application/json' and the body as 'raw' with the following JSON format:

{
    "sender": "sender-address",
    "recipient": "recipient-address",
    "amount": 10
}

5. Get the transaction pool

Get the transaction pool by requesting the endpoint http://localhost:1337/blockchain/transaction-pool with a GET request.

6. Validate the blockchain

Validate the blockchain by requesting the endpoint http://localhost:1337/blockchain/validate with a GET request.
