IoTeX (IOTX) is a blockchain platform designed to bridge the gap between smart devices and decentralized applications (DApps), enabling a trustless, autonomous machine economy. Since its inception as an open-source project in 2017, IoTeX has evolved into a robust, EVM-compatible blockchain infrastructure focused on empowering real-world machine interactions through secure, privacy-preserving technologies.
This article explores the core aspects of IoTeX — from its technological innovations and ecosystem growth to tokenomics and market presence — providing a comprehensive overview for investors, developers, and tech enthusiasts interested in the intersection of blockchain and the Internet of Things (IoT).
What Is IoTeX (IOTX)?
At its foundation, IoTeX aims to build an open economy for machines — a decentralized ecosystem where humans and devices can interact securely, autonomously, and with guaranteed trust. Unlike traditional blockchains that focus solely on financial transactions, IoTeX extends blockchain functionality to physical devices like smart cameras, sensors, and edge computing hardware.
The platform launched in April 2019 with a custom-built blockchain leveraging an innovative consensus mechanism called Roll-DPoS (Delegated Proof-of-Stake with rollup integration). This hybrid model combines high throughput and low latency with decentralization, supported by over 100 globally distributed delegates. To date, the network has processed more than 10 million transactions.
IoTeX is fully EVM-compatible, meaning developers can deploy Ethereum-based DApps directly onto the IoTeX blockchain without rewriting code — all while benefiting from near-zero gas fees. This makes it an attractive alternative for scaling DApps burdened by high costs on Ethereum.

Core Infrastructure and Ecosystem Tools
To support seamless interaction between blockchains and real-world devices, IoTeX has developed several critical infrastructure components:
- ioPay Wallet: A non-custodial wallet that supports multiple chains including Ethereum, Binance Smart Chain (BSC), and IoTeX. It enables users to manage digital assets and interact with DApps across ecosystems.
- ioTube Bridge: A cross-chain interoperability solution connecting IoTeX with Ethereum, BSC, and HECO. This allows frictionless transfer of assets and data, enhancing liquidity and accessibility.
- Decentralized Identity (DID): Enables self-sovereign identities for machines, allowing devices to authenticate themselves without centralized oversight.
- Confidential Computing & Secure Hardware: Ensures data privacy even during processing, making it ideal for sensitive IoT applications.
These tools collectively empower what IoTeX calls "autonomous machines" — devices capable of making decisions, executing smart contracts, and participating in economic activities independently.
Real-World Applications: Ucam and Pebble
One of IoTeX’s most notable implementations is Ucam, a privacy-first smart home security camera. Unlike conventional cloud-dependent cameras, Ucam stores video locally and uses blockchain to prove footage integrity. Users maintain full control over their data, and the device has already been deployed in over 3,000 households worldwide.
Another breakthrough is Pebble, a decentralized oracle solution launched to more than 300 developers. Pebble connects real-world data — such as weather conditions or sensor readings — to blockchain-based applications, enabling use cases like:
- Real-world NFTs: Tokenizing physical assets with verifiable provenance.
- Weather derivatives: Creating insurance or financial products based on real-time environmental data.
- Machine learning via mining: Incentivizing edge devices to contribute computational power for AI training.
These applications demonstrate how IoTeX turns passive devices into active participants in the decentralized economy.

What Makes IoTeX Unique?
While many blockchains focus on finance or general-purpose smart contracts, IoTeX stands out by targeting the machine-to-machine (M2M) economy. Key differentiators include:
- Device-Centric Architecture: Built specifically for IoT integration.
- Privacy by Design: Leverages secure enclaves and zero-knowledge proofs to protect sensitive data.
- Scalability Without Sacrifice: Roll-DPoS ensures fast finality and high transaction throughput while maintaining decentralization.
- Cross-Chain Interoperability: Native bridges enable asset and data flow across major blockchains.
- EVM Compatibility: Lowers entry barriers for developers familiar with Ethereum tooling.
This combination positions IoTeX at the forefront of the Web3 IoT movement — where trustless automation meets real-world utility.
Tokenomics: How Many IoTeX (IOTX) Coins Are in Circulation?
The native cryptocurrency of the IoTeX network is IOTX, which serves multiple functions:
- Staking and Governance: Users can stake IOTX to become delegates or vote for them, securing the network and earning rewards.
- Gas Fees: Used to pay for transaction execution and smart contract deployment.
- Incentive Mechanism: Rewards device operators and developers contributing to the ecosystem.
The total supply of IOTX is capped at 10 billion tokens. As of now, over 9 billion are in circulation, with inflation gradually decreasing due to staking rewards being funded from newly minted tokens at a diminishing rate.
Staking participation remains strong, with a significant portion of circulating supply locked in delegation pools — reflecting confidence in long-term network growth.
How Is the IoTeX Network Secured?
Security is achieved through the Roll-DPoS consensus algorithm, which merges the efficiency of DPoS with layer-2 style rollup techniques for enhanced scalability. The network relies on elected delegates (validators) who are responsible for block production and transaction validation.
Users stake IOTX tokens to vote for delegates, aligning incentives between token holders and network operators. Misbehaving nodes risk losing their staked deposits through slashing mechanisms.
Additionally, IoTeX integrates hardware-level security features like Trusted Execution Environments (TEEs) to ensure data integrity from edge devices all the way to the blockchain — a crucial requirement for IoT applications.
Where Can You Buy IoTeX (IOTX)?
IOTX is listed on several major cryptocurrency exchanges, including OKX, Bybit, KuCoin, and Gate.io. Trading pairs typically include USDT, BTC, and ETH.
To purchase IOTX:
- Choose a reputable exchange supporting IOTX.
- Complete identity verification (KYC if required).
- Deposit funds via fiat or crypto.
- Place an order for IOTX in your preferred trading pair.
Once acquired, users are encouraged to store IOTX in secure wallets like ioPay or other non-custodial solutions.

Frequently Asked Questions (FAQ)
Q: Is IoTeX compatible with Ethereum?
A: Yes. IoTeX is fully EVM-compatible, allowing developers to deploy Ethereum-based smart contracts directly onto the IoTeX blockchain with minimal changes.
Q: What is Roll-DPoS?
A: Roll-DPoS is a hybrid consensus mechanism combining Delegated Proof-of-Stake with rollup-like optimization for faster transaction finality and lower costs while maintaining decentralization.
Q: Can I stake IOTX tokens?
A: Absolutely. You can stake IOTX either by becoming a delegate or voting for one. Stakers earn rewards in additional IOTX tokens.
Q: How does Ucam ensure privacy?
A: Ucam stores video footage locally on the device rather than in the cloud. Blockchain is used only to verify tamper-proof timestamps and integrity — your data stays private.
