## Overview

{% hint style="warning" %}
The IOTX utility and tokenomics are being updated in IoTeX 2.0.\
Please refer to [-> IoTeX 2.0 Tokenomics](broken://pages/GJHOGj04VpgqdwSuyc7O)
{% endhint %}

The IOTX token, commonly known as "*iotex*," serves as the native cryptocurrency of the IoTeX blockchain, playing a role similar to Ether (ETH) in Ethereum. It underpins a marketplace for computational power, ensuring that nodes who run the blockchain are financially motivated to validate and process transactions, as well as to supply the computational power required to execute smart contracts across the network. This mechanism is vital for maintaining the network's operation and efficiency.

## Transaction fees

In the IoTeX network, anyone initiating a transaction must pay a fee in IOTX, similar to Ethereum's transaction fee structure. This fee compensates the network nodes responsible for validating, executing, and recording the transaction on the blockchain. The size of the fee corresponds to the computational effort required for the transaction, helping to prevent network abuse by discouraging excessively demanding computational tasks without appropriate compensation.

## IOTX Token utility

IOTX serves multiple crucial roles in maintaining the crypto-economic security of the IoTeX network:

**Rewards:** IOTX is used to reward nodes who successfully propose new blocks and identify fraudulent activities within the network.

**Staking by Validators:** Validator nodes stake IOTX as a form of commitment and collateral, helping to safeguard the network against dishonest behaviors.

**Delegate Election:** IOTX is crucial for staking by token holders, who use it to vote for delegates. This process is vital for maintaining decentralized governance and overall network security.

**Burn-Drop Mechanism:** In a unique deflationary tactic specific to the IoT environment, IOTX implements the "Burn-Drop" scheme. Whenever a new IoT device is registered on the IoTeX blockchain, a specified number of tokens are burned, and a corresponding amount is airdropped to stakers, simultaneously reducing the total supply and rewarding active participants.

## IOTX Token Fractions <a href="#iotx-fractions" id="iotx-fractions"></a>

6 fractions of the IOTX token are defined, where `1 Rau` is the smallest `IOTX` token unit:

| Fraction | IOTX Value | Rau Value |
| -------- | ---------- | --------- |
| 1 Rau    | 10⁻¹⁸ IOTX | 1 Rau     |
| 1 Krau   | 10⁻¹⁵ IOTX | 10³ Rau   |
| 1 Mrau   | 10⁻¹² IOTX | 10⁶ Rau   |
| 1 Grau   | 10⁻⁹ IOTX  | 10⁹ Rau   |
| 1 Qev    | 10⁻⁶ IOTX  | 10¹² Rau  |
| 1 Jing   | 10⁻³ IOTX  | 10¹⁵ Rau  |
| 1 IOTX   | 1 IOTX     | 10¹⁸ Rau  |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.iotex.io/blockchain/learn-iotex/the-iotx-token.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
