The Internet of Things (IoT) is ushering in a new era of traceability and machine-driven economies. As this technology expands, it’s increasingly being integrated into systems across industries. The convergence of blockchain networks and IoT systems unlocks unprecedented levels of interoperability, security, and real-time responsiveness—creating a foundation for smarter, decentralized ecosystems.
What Is IoT?
The Internet of Things refers to the global network of billions of interconnected smart devices. To qualify as “smart,” a device must have built-in sensors and internet connectivity. Today’s IoT devices can transmit data and value in real time across networks, enabling automation, remote monitoring, and intelligent decision-making.
Key Advantages of IoT
There are several compelling reasons behind the rapid growth of IoT:
- Automation: IoT systems reduce the need for human intervention by monitoring operations and triggering actions based on real-time data.
- Efficiency: They eliminate bottlenecks in information flow caused by manual data entry, outdated hardware, or incompatible systems.
- Security & Identity: Devices can be assigned unique digital identities, ensuring secure communication between machines.
When combined with blockchain, IoT becomes even more powerful—offering tamper-proof data logs, transparent supply chains, and trustless machine-to-machine (M2M) transactions. This synergy is fueling innovation across logistics, energy, agriculture, and smart cities.
Below are 10 leading blockchain-powered IoT projects poised to reshape industries.
1. IOTA
IOTA stands as one of the most recognized names in blockchain IoT innovation. Introduced conceptually in 2015 and launched on mainnet in 2016, IOTA was designed specifically for the machine economy. It enables feeless transactions, supports smart contracts, and facilitates M2M communication at scale.
At its core is Tangle, a Directed Acyclic Graph (DAG)-based architecture that replaces traditional blockchain structures. Unlike blockchains that rely on miners or validators, Tangle requires each transaction to confirm two previous ones—resulting in faster processing and zero fees.
The native token, MIOTA, powers the ecosystem by enabling data transfer, smart contract execution, and network access. Despite facing a security breach in 2018, the team strengthened protocols and rolled out major upgrades like Chrysalis in 2021—boosting performance, stability, and developer adoption.
Today, IOTA is used in mobility, supply chain tracking, and industrial automation—making it one of the most mature IoT blockchain platforms.

2. Helium
Helium reimagines telecom infrastructure through a decentralized model. Founded in 2013 by Amir Haleem, Shawn Fanning, and Sean Carey, it launched its IoT-focused mainnet in 2019. The project gained widespread attention for disrupting traditional cellular networks using a community-powered wireless network.
Helium operates as a Decentralized Physical Infrastructure Network (DePIN). Users deploy hotspots that broadcast LoRaWAN, a low-power, long-range protocol ideal for connecting sensors and IoT devices across cities.
Participants earn HNT (Helium Network Token) for providing coverage and transferring data. In 2023, Helium migrated to the Solana blockchain to improve scalability and reduce congestion—signaling a strategic shift toward high-performance decentralized infrastructure.
With community governance and cross-sector use cases—from asset tracking to environmental monitoring—Helium continues to expand its global footprint.
3. Chainlink
Launched in 2017 by Sergey Nazarov and Steve Ellis, Chainlink is best known as a decentralized oracle network—but its role in IoT is equally transformative.
Oracles bridge off-chain data (like temperature readings or GPS locations from IoT sensors) with on-chain smart contracts. Since many IoT devices generate real-world data, they naturally serve as reliable oracles when secured through blockchain validation.
Chainlink addresses the “oracle problem” by decentralizing data sources and implementing cryptographic proofs. This ensures that sensor data fed into smart contracts is accurate, tamper-resistant, and trustworthy.
Its integration with IoT enables applications such as:
- Automated insurance claims based on weather events
- Real-time supply chain verification
- Predictive maintenance alerts triggered by machine diagnostics
As demand grows for verifiable real-world data, Chainlink’s role as an IoT enabler becomes increasingly critical.
4. IoTeX
Founded in 2017 by Raullen Chai, Qevan Guo, Xinxin Fan, and Jing Sun, IoTeX is an open-source blockchain platform built specifically for IoT applications. Designed to power smart cities and connected devices, IoTeX emphasizes privacy, scalability, and security.
One of its standout features is full EVM compatibility, allowing Ethereum developers to seamlessly deploy dApps without rewriting code. This lowers the barrier to entry and accelerates innovation within the ecosystem.
IoTeX also integrates advanced cryptographic techniques like zero-knowledge proofs to protect user data—crucial for consumer-facing IoT products like wearables or home automation systems.
With over 40 research scientists contributing to its development and millions in transaction volume processed, IoTeX has earned a reputation as one of the most secure and developer-friendly IoT blockchains.
5. VeChain
VeChain entered the scene in 2016 with a strong enterprise focus—particularly in logistics and supply chain management. Its co-founder, Sunny Lu, formerly CIO of Louis Vuitton China, brought deep industry insight into complex global supply chains.
VeChain combines blockchain with IoT sensors to create real-time traceability for goods—from manufacturing to retail. Each product can be tracked via unique IDs linked to temperature, location, authenticity, and more.
Two key tokens power the network:
- VET: Used for value transfer and staking
- VeChainThor Energy (VTHO): Covers transaction fees (gas)
Enterprises use VeChain for anti-counterfeiting, carbon footprint tracking, and quality assurance—making it a top choice for companies seeking transparency in their operations.
6. NetObjex
NetObjex aims to standardize communication between IoT devices using blockchain technology. Standardization reduces redundancy and allows engineers to focus on innovation rather than compatibility issues.
The platform provides verified infrastructure for device identity management using NFT-based digital IDs. These unique tokens authenticate machines before granting access to sensitive data or systems—critical for industrial automation and secure M2M interactions.
Beyond IoT connectivity, NetObjex offers cybersecurity services and Web3 integration—positioning itself at the intersection of AI, blockchain, and connected devices.
7. ArcTouch
ArcTouch empowers businesses to integrate AI, blockchain, and IoT into customer-facing applications. Its flexible development tools simplify the creation of decentralized apps (dApps) that interact with smart devices like wearables, voice assistants, and smart TVs.
By combining real-time sensor data with blockchain validation, ArcTouch enhances both transparency and user trust. Recent advancements include AI-driven analytics layered over IoT inputs—enabling predictive insights while maintaining data integrity.
