Introduction

IoTeX is a Layer-1 blockchain platform built to connect smart devices and real-world data to decentralized networks. Its core mission is to power Decentralized Physical Infrastructure Networks (DePIN) — a model where physical hardware and devices are governed and operated without central control.

At its heart, IoTeX bridges the physical and digital worlds, enabling machines, sensors, and IoT devices to interact with blockchain-based applications in a secure and transparent way.

History & Background

IoTeX was founded in 2017 by a team of cryptographers and engineers, and its mainnet launched in 2018. The project was designed from the ground up to tackle privacy, scalability, and interoperability challenges specific to Internet of Things (IoT) networks.

In 2024, IoTeX launched IoTeX 2.0, a major upgrade introducing a modular DePIN infrastructure platform. This upgrade introduced DePIN Infrastructure Modules (DIMs) — composable building blocks covering hardware abstraction, connectivity, off-chain computing, and storage.

How IoTeX Works

IoTeX uses a Roll-DPoS (Randomized Delegated Proof-of-Stake) consensus mechanism. Token holders stake IOTX to vote for Delegates, who are responsible for validating transactions and securing the network.

The blockchain is EVM-compatible, meaning developers can deploy Ethereum-smart contracts directly on IoTeX. Its modular architecture lets builders pick and combine infrastructure components suited to their specific DePIN use case.

IoTeX also supports a Modular Security Pool (MSP), where module providers stake IOTX to contribute to ecosystem security and earn rewards.

Tokenomics

IOTX is the native currency of the IoTeX ecosystem. It serves multiple roles:

  • Paying transaction fees on the network
  • Staking to vote for Delegates and earn rewards
  • Participating in on-chain governance
  • Powering DePIN applications and module providers

IoTeX follows a deflationary model, with a hard cap of 10 billion IOTX tokens. A significant portion of the circulating supply is staked at any given time, reducing sell pressure.

Ecosystem & Use Cases

The IoTeX ecosystem includes hundreds of projects spanning DePIN, decentralized identity, data exchange, and device tracking. Real-world applications include home security, environmental monitoring, and renewable energy solutions.

Key ecosystem tools include ioPay (the native wallet), ioTube (a cross-chain bridge), and DePINscan (a DePIN project explorer). The platform supports over 100 tokens and serves a large base of monthly active users.

Team, Governance & Community

IoTeX operates as a decentralized ecosystem with no single controlling entity. Governance is community-driven: IOTX holders stake tokens to elect Delegates and vote on network proposals.

The top-voted Consensus Delegates earn additional rewards per epoch, incentivizing active participation. The IoTeX Foundation supports core development and ecosystem growth through public goods funding.

Advantages

  • Purpose-built for DePIN and IoT, with a specialized architecture designed for real-world device integration
  • EVM compatibility makes it easy for Ethereum developers to build on IoTeX
  • Modular design with DIMs reduces time and cost for DePIN builders
  • Deflationary tokenomics and high staking participation support long-term network health
  • Cross-chain bridges connect IOTX to Ethereum, BNB Smart Chain, Polygon, and Base

Risks & Challenges

  • Competitive landscape: IoTeX faces growing competition from other DePIN-focused platforms and general-purpose Layer-1s
  • Adoption dependency: Success relies on widespread adoption of IoT and DePIN hardware, which faces regulatory and logistical hurdles
  • Market maker risk: A third-party market maker incident in 2025 temporarily disrupted trading, highlighting ecosystem counterparty risks
  • Complexity: The modular infrastructure, while flexible, adds technical complexity for new builders

Long-Term Vision

IoTeX envisions a future where 100 million devices are connected to decentralized networks, unlocking trillions of dollars in real-world value on the blockchain. By combining zero-knowledge proofs, AI, and modular blockchain infrastructure, IoTeX aims to make DePIN accessible to everyday users and builders alike — creating a more open, transparent, and user-owned internet of physical things.

Frequently Asked Questions

IoTeX is a Layer-1, EVM-compatible blockchain platform designed to power Decentralized Physical Infrastructure Networks (DePIN) and IoT applications. It connects smart devices and real-world data to decentralized networks.

IOTX is the native token of the IoTeX network, used for paying transaction fees, staking to vote for Delegates, participating in governance, and powering DePIN applications and modules.

DePIN stands for Decentralized Physical Infrastructure Network — a framework for building and operating physical device networks without centralized control. IoTeX focuses on DePIN because it sees this model as the future of connected infrastructure.

IoTeX uses Roll-DPoS (Randomized Delegated Proof-of-Stake). Token holders stake IOTX to vote for Delegates who validate transactions and secure the network.

IoTeX 2.0 is a major platform upgrade launched in 2024 that introduced a modular DePIN infrastructure with composable DePIN Infrastructure Modules (DIMs). It aims to reduce the time, cost, and resources needed for DePIN builders to go to market.

Yes, IoTeX is EVM-compatible, meaning Ethereum smart contracts and developer tools work natively on the IoTeX blockchain. IOTX tokens are also bridgeable to Ethereum, BNB Smart Chain, Polygon, and Base.

IOTX has a hard cap of 10 billion tokens. The tokenomics follow a deflationary model, and a large portion of the circulating supply is staked at any given time.

IoTeX is governed in a decentralized manner by its community. IOTX holders stake tokens to elect Delegates and vote on network proposals, with no single entity owning or controlling the network.
