IoTeX evolved from an IoT-focused blockchain into a comprehensive platform for decentralized physical infrastructure networks (DePIN). Roll-DPoS consensus delivers 2,000 TPS and 2.5-second block times. W3bstream middleware verifies real-world data before on-chain settlement, enabling trustless machine-to-machine finance (MachineFi). The platform demonstrates successful market adaptation while maintaining technical commitment to real-world asset integration, secure settlement, and trustless machine transactions at scale.
History and founding
Raullen Chai founded IoTeX in 2018 with a vision to enable blockchain technology for the Internet of Things ecosystem. Existing blockchain infrastructure was poorly optimized for IoT device networks, which require high throughput, low latency, and privacy-preserving design to replace centralized IoT platforms.
The project started with academic research into IoT blockchain requirements, producing technical papers on device-to-device communication, edge computing integration, and trustless settlement mechanisms. This research foundation distinguished IoTeX from purely market-driven cryptocurrency projects.
Mainnet launched on April 22, 2019, with functional EVM compatibility enabling Ethereum smart contract deployment. This early EVM implementation positioned IoTeX as developer-friendly, allowing Solidity developers to migrate applications without retraining.
From 2021-2023, IoTeX maintained focus on IoT infrastructure while the market shifted toward DeFi and NFTs. Rather than abandoning the IoT vision, the team recognized that decentralized physical infrastructure networks represented the maturing application of blockchain-enabled IoT. This strategic pivot repositioned IoTeX as fundamental infrastructure for the emerging DePIN market without abandoning technical commitments.
The Q2 2024 $50 million funding round signaled renewed market validation and accelerated protocol development.
Technical architecture
IoTeX combines EVM-compatible Layer 1 blockchain infrastructure with off-chain computation middleware and open hardware layers, creating an end-to-end DePIN solution stack.
Roll-DPoS combines delegated proof-of-stake token holder democracy with deterministic randomization preventing delegate collusion. The mechanism works as follows:
Any IOTX holder can stake tokens to become a candidate. The top 36 candidates by stake become eligible delegates.
Each epoch, 24 of the 36 eligible delegates are randomly selected through verifiable random functions (VRFs) to form the block-producing committee. This randomization prevents small cabals from controlling consensus.
Selected delegates propose blocks through practical Byzantine Fault Tolerance, achieving finality within 15 seconds (6 block confirmations at 2.5-second block times).
Block production rewards distribute to delegates and their staking voters, creating economic incentive for continued participation.
The June 19, 2025 v2.2.0 hard fork significantly enhanced consensus efficiency. Block time reduced from 5 seconds to 2.5 seconds. Theoretical throughput increased to 2,000 transactions per second, positioning IoTeX as one of the fastest EVM-compatible blockchains.
W3bstream provides an off-chain computation layer for verifying real-world data before on-chain settlement. Rather than forcing IoT data directly on-chain, this architecture enables:
W3bstream verifies sensor data, computational results, and device states without requiring on-chain verification. Multiple IoT devices report data through W3bstream, which aggregates and compresses into efficient on-chain representations. Sensitive device data remains off-chain, with only verified results stored on-chain. Off-chain verification eliminates gas costs for data validation, dramatically reducing IoT application costs.
W3bstream enables developers to build applications like decentralized GPS location verification without continuous on-chain updates, sensor data aggregation for environmental monitoring with tamper-proof proofs, and device reputation systems based on verifiable behavior history.
IoTeX implements full Solidity smart contract compatibility, enabling developers to deploy existing Ethereum applications without modification. This compatibility removes significant adoption barriers for developers familiar with Ethereum development tooling.
Unlike purely software-based blockchains, IoTeX invests in open hardware. Pebble Tracker and similar IoTeX-optimized IoT devices provide reference implementations enabling developers to build integrated hardware-blockchain applications.
Ecosystem and adoption
IoTeX cultivated the most advanced DePIN-specific ecosystem in blockchain, with 218+ projects building on the platform as of 2025, including 51 dedicated DePIN projects.
Marshall DAO allocates incentives (200+ million IOTX annually) to fund DePIN projects and protocol development. This incentive mechanism attracted leading DePIN projects including:
Pebble Tracker provides GPS tracking devices generating verifiable location data. Helium's IoTeX deployment provides wireless network infrastructure earning rewards for coverage provision. WeatherXM operates weather station networks monetizing environmental data. Akasha Network provides decentralized social graph and content platform functionality. Vanywhere offers verifiable digital identity and reputation systems.
Q1 2025 saw IoTeX launch Quicksilver, an AI agent framework enabling autonomous agents to collect and act on decentralized physical data. This development bridges AI and DePIN, creating feedback loops where machines generate data, AI processes insights, and autonomous agents execute actions.
Vodafone-led alliance aims to tokenize 10,000+ mobile towers as DePIN nodes by mid-2026. This partnership represents unprecedented telecom sector engagement with blockchain infrastructure, potentially transforming wireless network economics.

Tokenomics
IOTX functions as the mechanism for securing the network, incentivizing data provision, and participating in governance. The 10 billion IOTX token supply has a fixed maximum cap. At mainnet launch in April 2019, this represented a large total supply compared to contemporary blockchains, reflecting IoTeX's emphasis on accessibility over artificial scarcity.
As of August 2025, approximately 9.6 billion IOTX are in circulation, representing 96% of maximum supply. The remaining supply consists of locked developer allocations and incentive reserves.
Over 3.8 billion IOTX (38% of total supply) is staked by community delegates and voters. This represents exceptional staking participation, indicating strong community engagement with governance and economic incentives.
Marshall DAO annual allocations (200+ million IOTX) create direct economic incentives for DePIN infrastructure development. This allocation model ensures sustained funding for ecosystem growth without requiring venture capital or external funding.
Block-producing delegates receive IOTX rewards proportional to block production. These rewards create economic incentive for continuous network participation and technical sophistication.
IOTX holders who delegate to validators receive voting rewards proportional to their delegation amount and duration. This creates economic incentive for token holder governance participation.
IoTeX implements predictable inflation controlled through governance proposals. This transparency enables stakeholders to anticipate supply changes and adjust economic models accordingly.
Governance and development
IOTX token holders participate in governance by staking tokens to validators of their choice. This delegation mechanism creates direct economic linkage between governance voting power and economic commitment to network success.
