Creating the createNewTransaction method

The next method that we are going to add to our blockchain constructor function is called createNewTransaction. This method will create a new transaction for us. Let's follow the below mentioned steps to create the method: 

1. Start building up this method by adding the following line of code after our getLastBlock method:

Blockchain.prototype.createNewTransaction = function () {}

2. The function () will take three parameters, such as the following:

Blockchain.prototype.createNewTransaction = function (amount, sender, recipient) {}

What these three parameters will do is as follows: 

• amount: This parameter will take in the amount of the transaction or how much is being sent in this transaction.
• sender ...
