Instant Pay With IOTA

The IOTA Foundation invented a new protocol for distributed ledgers with no transactions fees. The Tangle is a safe technology for storing these transactions. We will soon be able to pay for services provided to us for example by driverless cars using IOTA.

A Few IOTA Terms:

• Address - address of recipient
• Seed - "wallet" containing value called "iota"
• The Tangle - web of transactions
• Testnet - Tangle testbed
• Tryte - "IOTA byte" with three states: 1, 0, -1
• Wallet - container for value called "iota"

Example:

In the following example I'll be demonstrating a zero value transaction for demonstration purposes.

Step 1:

The First step involves selecting an IOTA Library and Node.

IOTA Library URL: 

const IOTA = require("iota.lib.js")

const iota = new IOTA({provider: "https://nodes.testnet.iota.org:443"})

const remoteCurl = require('@iota/curl-remote')

remoteCurl(iota, `https://powbox.testnet.iota.org`, 500)

Step 2:

Now we have to confirm that the Node works.

Confirmation Code:

iota.api.getNodeInfo((error, success) => {

if (error) {

console.log(error)

} else {

console.log(success)

}

})

Step 3:

Input Transaction Data:

Input value, address, and message:

• value - zero "IOTAs" are being sent
• address - address of recipient in "trytes"
• (replace Test... with your 81 character tryte)
• message - YourMessage converted to trytes

Input Transaction Code: 

const trytes = 'Test'

const message = iota.utils.toTrytes('YourMessage')

const transfers = [

{

value: 0,

address: trytes,

message: message

}

]

Step 4:

Send Transaction Data:

Prepare the transfer and attach to the Tangle then broadcast and store the transaction.

Send Transaction Code:

iota.api.sendTransfer(trytes, 3, 9, transfers, (error, success) => {

if (error) {

console.log(error)

} else {

console.log(success)

}

})
