The Internet of Things (IoT) is rapidly transforming how devices communicate, transact, and share data. Yet, traditional blockchain systems struggle to keep up with the scale, speed, and efficiency demands of a world where billions of machines interact every second. Enter IOTA—a next-generation distributed ledger technology often referred to as "Blockchain 3.0"—engineered from the ground up to power the machine-to-machine economy.
At the heart of IOTA’s mission is a bold vision: to become the foundational infrastructure for IoT ecosystems. Unlike conventional blockchains, IOTA eliminates transaction fees, scales seamlessly with usage, and operates efficiently even on low-powered devices. This makes it uniquely suited for microtransactions, data integrity, and automated machine payments.
To understand how IOTA is redefining decentralized systems, we spoke with Lewis Freiberg, a 23-year-old ecosystem engineer and one of IOTA’s key technical advocates—often described as a “technology evangelist” for the project.

A New Architecture for IoT: Scalability, Zero Fees, and Lightweight Design
IOTA isn’t just an incremental upgrade—it’s a complete reimagining of distributed ledger technology. Its core innovation lies in Tangle, a novel architecture that replaces the linear chain of blocks with a directed acyclic graph (DAG). This allows transactions to be processed in parallel rather than in sequence, solving the scalability bottlenecks that plague Bitcoin and Ethereum.
How Tangle Works
In traditional blockchains like Bitcoin or Ethereum, miners validate transactions and group them into blocks. As network activity increases, so does congestion—leading to slower confirmation times and higher fees. This model doesn’t scale well for IoT environments where millions of devices may need to transact instantly and frequently.
Tangle eliminates miners entirely. Instead, each user who submits a transaction must first validate two previous transactions. This user-validated consensus mechanism ensures that the network secures itself through participation. The more users transact, the faster and more secure the network becomes.
“Bitcoin handles about 3–4 transactions per second. Ethereum manages around 15. We’ve already achieved 38 TPS—and our speed increases as more people join,” explains Freiberg.
This self-reinforcing system enables IOTA to support high-frequency, low-value transactions—the exact type needed for IoT applications such as pay-per-minute Wi-Fi access, usage-based energy billing, or autonomous vehicle toll payments.
Zero Transaction Fees
One of IOTA’s most disruptive features is its zero-fee transaction model. Since there are no miners to reward, users don’t pay fees. This opens the door to micropayments—transferring fractions of cents between machines without economic inefficiency.
Imagine your smart fridge automatically ordering milk when supplies run low and paying the delivery drone by the second of service rendered. Or solar panels selling excess energy directly to neighboring homes in real time. These scenarios become feasible only when transaction costs approach zero.

Lightweight and Efficient
Another critical advantage is IOTA’s lightweight footprint. While Ethereum’s blockchain has grown to over 140GB, IOTA’s Tangle remains under 5GB—even with growing adoption. This efficiency stems from a built-in data pruning mechanism that removes non-essential information at regular intervals.
As a result, IOTA can run efficiently on resource-constrained devices like sensors, wearables, or embedded chips—making it ideal for edge computing and decentralized IoT networks.
Real-World Applications: From Smart Cars to Data Marketplaces
IOTA isn’t just theoretical. It’s already being tested and deployed in real-world partnerships across industries.
Automotive Innovation with Volkswagen
Volkswagen has experimented with IOTA to secure data from connected vehicles. By storing telemetry data—such as speed, location, system status, and autonomous driving logs—on the Tangle, the company ensures immutable records that cannot be tampered with.
This has major implications for secondhand car markets, where accurate mileage and maintenance history can prevent fraud. Additionally, cars equipped with IOTA-powered wallets can autonomously pay for parking, tolls, or charging—enabling true machine-to-machine (M2M) economies.
Smart Charging Infrastructure
ElaadNL, a Dutch startup focused on electric vehicle infrastructure, uses IOTA to manage microtransactions at smart charging stations. Drivers are billed precisely for the amount of electricity used, with transactions recorded securely on the distributed ledger—no intermediaries required.
Building the Future: The IOTA Data Marketplace
Beyond payments, IOTA is pioneering a new paradigm: data as a tradable asset.
In a landmark collaboration, IOTA has joined forces with global tech giants—including Cisco, Microsoft, Fujitsu, Samsung, and Huawei—to launch the Data Marketplace. This platform enables organizations to securely store, share, and monetize sensor-generated data using IOTA’s distributed ledger.
Here’s how it works:
- Sensors collect environmental data (e.g., air quality, temperature, traffic patterns).
- Data is hashed and stored on Tangle, ensuring authenticity and timestamping.
- Other parties can purchase access rights directly through the network using IOTA tokens.
- All transactions are transparent, secure, and automated.
This creates new revenue streams for cities, manufacturers, and researchers while promoting open innovation and data transparency.
Addressing Security Concerns: The Role of the Coordinator
Despite its promising design, IOTA acknowledges that full decentralization takes time. Currently, the network relies on a temporary component called the Coordinator (Coo)—a centralized node that issues periodic checkpoints to prevent double-spending attacks during periods of low activity.
Freiberg compares this to training wheels: “Just like Bitcoin and Ethereum had centralized elements in their early days, we use the Coordinator to ensure security while adoption grows.” The long-term roadmap includes removing the Coordinator entirely as transaction volume increases and network resilience strengthens.

Frequently Asked Questions (FAQ)
Q: Is IOTA a blockchain?
A: No. IOTA uses Tangle, a directed acyclic graph (DAG)-based distributed ledger that doesn’t rely on blocks or chains. This allows for greater scalability and feeless transactions.
Q: Can I mine IOTA tokens?
A: No. IOTA does not use mining or staking. All tokens were created at launch, and no new ones will ever be issued.
Q: Why does IOTA need a Coordinator?
A: The Coordinator is a temporary security measure to protect the network during low-traffic periods. It will be phased out once the network reaches sufficient transaction volume for full decentralization.
Q: What makes IOTA suitable for IoT devices?
A: Its lightweight design, zero fees, fast confirmations, and ability to run on low-power hardware make IOTA ideal for machine-to-machine communication and microtransactions.
Q: Which companies are using IOTA today?
A: Volkswagen, ElaadNL, Cisco, Microsoft, Fujitsu, Samsung, and Huawei are among the major partners testing or deploying IOTA in real-world applications.
Q: How does IOTA handle data privacy?
A: While transaction metadata is stored immutably on Tangle, sensitive data can be encrypted off-chain. Access controls allow owners to share data selectively via secure tokens.
The Road Ahead
IOTA represents more than just a technological leap—it’s a shift toward a decentralized machine economy where devices interact autonomously, securely, and efficiently. While challenges remain in achieving full decentralization and widespread adoption, the foundation is being laid through strategic partnerships and real-world pilots.
As Lewis Freiberg puts it: “Technology isn’t valuable unless it’s useful.” And usefulness begins with solving real problems—like enabling trillions of connected devices to transact without friction.
With its unique blend of scalability, security, and sustainability, IOTA stands poised to become the backbone of the IoT revolution—one feeless transaction at a time.
