What is IoTeX?

IoTeX (IOTX) is a decentralized Layer 1 blockchain purpose-built for the Internet of Things (IoT), designed to connect billions of smart devices and real-world data streams to Web3. Founded in 2017 by a team of Ph.D. engineers and research scientists including Raullen Chai (former Head of Cryptography R&D at Uber), Qevan Guo (former Research Scientist at Meta), Jing Sun, and Xinxin Fan, the project was built from the ground up to address scalability, privacy, and machine-scale throughput limitations of general-purpose blockchains.

IoTeX launched its mainnet, known as Mainnet Alpha, in April 2019, followed by the EVM-compatible Mainnet GA upgrade that opened the network to Ethereum developers and tooling. The network uses Roll-DPoS, a variant of Delegated Proof of Stake that randomizes delegate selection to achieve instant finality, sub-5-second block times, and energy-efficient consensus suitable for machine-generated transaction volumes.

At the heart of the ecosystem is MachineFi, IoTeX's flagship paradigm for tokenizing the data and utility generated by real-world devices, and W3bstream, an off-chain compute layer that verifies real-world data using zero-knowledge proofs and trusted execution environments before anchoring the results on-chain. Flagship consumer products include Ucam, a privacy-focused home security camera that gives users full ownership of their video data, and Pebble Tracker, a blockchain-powered GPS and environmental sensor used in logistics, carbon tracking, and supply-chain verification — both of which debuted at CES, where IoTeX has exhibited multiple years running and received CES Innovation Awards.

The ecosystem has grown to include DePIN projects leveraging IoTeX infrastructure for decentralized wireless, health data, environmental monitoring, and EV charging networks, positioning IoTeX as one of the earliest and most established players in the Decentralized Physical Infrastructure Networks (DePIN) narrative that gained mainstream crypto attention in 2023 and 2024.

IoTeX has formed partnerships and collaborations with organizations such as the IoTeX Alliance members, R Discovery, Google Cloud (as a validator partner during earlier network phases), and various hardware manufacturers producing MachineFi-compatible devices. The project is a founding member of the DePIN Alliance, which brings together protocols including Peaq, Nodle, and others to standardize identity, messaging, and interoperability for machine-to-machine economies.

IOTX, the native token, is used for staking, governance, gas fees on the IoTeX chain, and as the settlement currency for MachineFi applications. The network has undergone several major upgrades, including the Haechi hardfork that improved staking mechanics and the Redwood release that introduced further EVM enhancements and Realms, a framework enabling modular sub-networks and appchains tailored for specific DePIN verticals.

While IoTeX has not been at the center of major controversies, like many smaller-cap altcoins it has experienced significant volatility tied to broader crypto market cycles and the rotational interest in the DePIN sector. The project maintains active developer documentation, open-source repositories, an ioPay wallet, and block explorers at iotexscan.io, and it continues to publish quarterly roadmaps describing progress toward its long-term vision of a truly decentralized machine economy in which physical devices autonomously participate in onchain finance, governance, and data markets.

Key Features of IoTeX

• Roll-DPoS Consensus: IoTeX uses Roll-DPoS, a randomized Delegated Proof of Stake mechanism that selects a subset of delegates each epoch to produce blocks. This design delivers sub-5-second block times, instant finality, and Byzantine fault tolerance while keeping energy consumption dramatically lower than Proof of Work networks.
• MachineFi Framework: MachineFi is IoTeX's native paradigm for financializing machine-generated data and services. It allows hardware owners to register devices on-chain, stream verified data, and earn IOTX or application tokens, turning sensors, cameras, and trackers into productive crypto-economic assets.
• W3bstream Compute Layer: W3bstream is an off-chain compute network that ingests real-world data from IoT devices, validates it using zero-knowledge proofs and trusted execution environments, and submits cryptographic attestations to the IoTeX chain. This lets smart contracts react to verified physical events without bloating the base layer with raw IoT traffic.
• Full EVM Compatibility: IoTeX is fully EVM-compatible, so Solidity contracts, MetaMask, Hardhat, Foundry, and Ethereum tooling work natively on the network. Developers can port Ethereum dApps with minimal changes while gaining access to DePIN-specific modules and cheaper transaction fees.
• Realms Appchain Architecture: Through the Realms framework, projects can deploy modular appchains and sub-networks tailored to specific DePIN verticals such as mobility, energy, or health data. Each Realm inherits IoTeX security and interoperability while customizing throughput, privacy, and governance for its use case.

IoTeX Use Cases

• DePIN Networks: IoTeX powers Decentralized Physical Infrastructure Networks where real-world hardware such as wireless hotspots, environmental sensors, and EV chargers coordinate and earn rewards on-chain. Builders use W3bstream to prove device uptime and output, then distribute tokens to contributors without centralized gatekeepers.
• Supply Chain Verification: Pebble Tracker and similar IoTeX-compatible devices attach to shipments to record GPS location, temperature, humidity, and shock data onto the blockchain. This creates a tamper-resistant audit trail for pharmaceuticals, perishables, and high-value logistics, reducing disputes and fraud.
• Privacy-Preserving Smart Homes: Consumer devices like the Ucam security camera let owners control encryption keys so footage is never exposed to centralized cloud providers. Combined with on-chain identity, this enables smart homes where users, not manufacturers, own and monetize their device data.
• Machine-to-Machine Payments: IoTeX supports autonomous micropayments between devices, such as an EV paying a charger, a drone paying for airspace access, or a sensor selling its data stream. Low fees and fast finality make settlement practical at the sub-cent scale required for machine economies.
• Tokenized Health and Fitness Data: Wearables integrated with IoTeX can reward users for sharing verified activity, sleep, or biometric data with researchers, insurers, or wellness dApps. Zero-knowledge proofs let users earn IOTX or app tokens without revealing raw personal information.

IoTeX Tokenomics

Total Supply

IOTX launched with a maximum supply of 10 billion tokens. The network transitioned to a deflationary model through the Burn-Drop mechanism introduced in earlier upgrades, which burns a portion of IOTX each time new devices are registered to the network.

Circulating

A majority of the 10 billion IOTX supply is in circulation, with the remainder allocated to ecosystem, team, and foundation vesting schedules.

Utility

IOTX is used to pay gas fees on the IoTeX chain, stake with delegates to secure the network, participate in on-chain governance, and settle transactions within MachineFi and DePIN applications. It is also required for registering MachineFi devices and accessing W3bstream compute resources.

Emission

New IOTX enters circulation primarily through staking rewards distributed to delegates and their voters each epoch, while Burn-Drop events remove IOTX from supply as the device ecosystem grows. Net emission therefore depends on the balance between staking issuance and device-registration burns, trending deflationary as DePIN adoption expands.
