What is Helium?

Helium is a decentralized wireless network that leverages blockchain technology to create a global, peer-to-peer infrastructure for the Internet of Things (IoT). It enables devices to connect to the internet without relying on traditional cellular, Wi-Fi, or satellite connections. Instead, Helium uses a distributed network of user-operated hotspots that provide wireless coverage in exchange for cryptocurrency rewards.

This innovative approach combines blockchain, wireless technology, and cryptoeconomics to solve one of the major challenges in IoT adoption: the high cost and limited range of existing connectivity options. Helium aims to build what it calls “The People’s Network,” a system where individuals contribute to network growth and are rewarded for their participation.

Launched in 2019 by Helium Systems, Inc., the project has grown into one of the most successful examples of blockchain-powered physical infrastructure. It represents a new paradigm known as “DePIN” (Decentralized Physical Infrastructure Network), where blockchain incentivizes users to build and maintain real-world systems such as telecommunications, computing, or energy networks.

The Concept Behind Helium

At its core, Helium was created to address inefficiencies in IoT connectivity. Traditional networks such as 4G, 5G, and Wi-Fi are often too expensive or power-intensive for low-bandwidth IoT devices like sensors, trackers, and smart meters. Helium’s decentralized model provides a low-cost and energy-efficient alternative.

The network is powered by user-deployed hotspots that act as both wireless access points and blockchain nodes. These hotspots provide LongFi coverage, a combination of LoRaWAN (Long Range Wide Area Network) and Helium’s blockchain technology. LoRaWAN is a low-power wireless communication protocol ideal for transmitting small amounts of data over long distances, often up to several kilometers.

By combining LoRaWAN with blockchain incentives, Helium encourages individuals and businesses to build and maintain a vast, global network. Instead of relying on telecom corporations, the infrastructure is collectively owned by the community.

Participants who run hotspots are rewarded in Helium’s native cryptocurrency, originally known as HNT. These rewards are distributed based on the coverage provided, data transferred, and participation in network validation.

This combination of wireless technology and decentralized economics allows Helium to operate as a self-sustaining ecosystem that grows organically as more users join and deploy devices.

How Helium Works

The Helium network operates through a combination of three primary components: hotspots, the blockchain, and the Helium token economy. Each part plays a specific role in maintaining and expanding the decentralized wireless system.

1. Hotspots: Hotspots are physical devices that provide wireless coverage using LoRaWAN technology. Each hotspot connects to nearby IoT devices and relays their data to the internet. In addition to providing coverage, hotspots also validate network activity and communicate with other hotspots to verify that real coverage exists.
2. Proof-of-Coverage (PoC): Helium uses a unique consensus mechanism called Proof-of-Coverage. It verifies that hotspots are actually providing wireless coverage in specific geographic locations. This verification process involves sending and receiving signals between nearby hotspots. Successful validation earns participants HNT rewards, ensuring that users are incentivized to deploy real, functional devices rather than fake nodes.
3. Helium Blockchain: The blockchain records all network activities, including hotspot locations, data transmissions, and reward distributions. It ensures transparency, security, and fairness. The Helium blockchain is designed for high efficiency and low energy use compared to traditional proof-of-work systems.
4. HNT Token: HNT is the native cryptocurrency of the Helium network. It serves two main purposes: rewarding participants and facilitating network usage. Hotspot owners earn HNT for providing coverage and transferring data. Meanwhile, network users (IoT device operators) must burn HNT to create Data Credits, which are used to pay for data transmission across the network. This burn-and-mint equilibrium helps regulate supply and demand.

Through these mechanisms, Helium aligns economic incentives with network expansion, creating a system where participants are both contributors and beneficiaries.

Proof-of-Coverage Explained

Proof-of-Coverage (PoC) is one of Helium’s most innovative features. It ensures that hotspots claiming to provide wireless service are actually doing so in their stated locations.

The PoC process involves three roles:

• Challenger: A randomly selected hotspot that creates and transmits a challenge to test network coverage.
• Transmitter: The hotspot that receives the challenge and broadcasts it to nearby hotspots.
• Witnesses: Nearby hotspots that hear the transmission and report back to the network, confirming the transmitter’s location and activity.

This triangulation process allows the network to verify coverage in real time without relying on centralized entities. Only hotspots that actively participate in PoC and contribute to legitimate coverage receive rewards.

The PoC system not only ensures integrity but also promotes geographic diversity. The more spread out and well-positioned the hotspots are, the better the overall network performance and reward distribution.

The Role of HNT and Data Credits

The Helium ecosystem relies on two core assets: HNT (Helium Network Token) and Data Credits (DC). These assets interact through a model that balances network incentives and usage.

1. HNT – The Incentive Token:
   HNT is distributed to participants who contribute to the network’s operation. Hotspot owners, validators, and developers can earn HNT for:
   • Providing wireless coverage verified through Proof-of-Coverage.
   • Transmitting data for IoT devices connected to the network.
   • Running validators that secure and manage the blockchain.
2. The supply of HNT is limited, making it a scarce asset. Over time, mining rewards are halved periodically, similar to Bitcoin, ensuring long-term scarcity and value preservation.
3. Data Credits – The Utility Token:
   Data Credits are a non-transferable utility token used to pay for data transmission and network services. They are created by burning HNT at a fixed rate, introducing a deflationary mechanism.
   This burn-and-mint model ensures that as network usage grows, more HNT is removed from circulation, balancing supply and demand.

This dual-token system creates a sustainable economic structure where rewards drive network growth and usage drives token value.

Migration to Solana and Network Expansion

In 2023, the Helium network underwent a major transformation by migrating from its own Layer 1 blockchain to the Solana blockchain. The migration aimed to improve scalability, performance, and developer accessibility.

By moving to Solana, Helium gained access to a larger ecosystem of decentralized applications and faster transaction processing. This transition also introduced subDAOs (sub-decentralized autonomous organizations) that focus on specific network verticals such as IoT and mobile services.

For example, the Helium IoT subDAO continues to manage the original IoT network based on LoRaWAN, while the Helium Mobile subDAO focuses on building a decentralized 5G network for smartphones and other mobile devices.

These expansions demonstrate Helium’s ambition to become a multi-network platform that supports a range of wireless technologies under a unified decentralized model.

Use Cases of Helium

Helium’s decentralized infrastructure has a wide range of practical applications across industries. It provides affordable, long-range connectivity for devices that need to send small packets of data efficiently.

Common use cases include:

1. Asset and Vehicle Tracking: Logistics companies use Helium to track vehicles, shipping containers, and goods across large areas without depending on cellular networks.
2. Environmental Monitoring: Sensors connected to the Helium network collect data on air quality, temperature, humidity, and pollution levels, helping cities and organizations monitor environmental conditions.
3. Smart Agriculture: Farmers use IoT devices powered by Helium to monitor soil moisture, crop health, and weather conditions, improving efficiency and reducing resource waste.
4. Smart Cities: Municipalities use Helium-connected sensors for parking management, waste collection, and energy monitoring, enabling smarter and more sustainable urban infrastructure.
5. Pet and Personal Tracking: Consumers use Helium-based devices to track pets, bikes, or personal items, benefiting from low-cost, long-range connectivity.

By enabling these use cases, Helium contributes to the growth of the IoT ecosystem while democratizing access to wireless connectivity.

Advantages of the Helium Network

Helium’s decentralized model provides several key advantages over traditional telecom networks:

1. Decentralization and Ownership: Unlike centralized providers, Helium allows individuals and businesses to own a piece of the network infrastructure and earn rewards for contributing coverage.
2. Low Costs: The network offers affordable data transfer rates, making it ideal for IoT applications where cost efficiency is critical.
3. Energy Efficiency: Helium’s LoRaWAN technology and Proof-of-Coverage mechanism require minimal energy, making it sustainable and eco-friendly.
4. Global Accessibility: Anyone with a hotspot can participate in the network, contributing to a global, open-source infrastructure.
5. Scalability and Flexibility: The integration with Solana and the creation of subDAOs enable Helium to scale and adapt to new technologies, including 5G and beyond.

These advantages position Helium as a leading example of how blockchain can transform physical infrastructure industries.

Challenges and Criticisms

Despite its success, Helium has faced challenges and criticism, particularly during its early stages of growth.

• Coverage Distribution: In the beginning, many hotspots were concentrated in specific regions, leading to inefficient network coverage in other areas.
• Profitability Concerns: As more hotspots joined the network, rewards per device decreased, leading to debates about sustainability.
• Hardware Quality and Scalability: The rapid expansion attracted manufacturers producing substandard hardware, affecting performance and user experience.
• Market Volatility: Like all blockchain projects, Helium’s token economy is influenced by cryptocurrency market fluctuations, impacting participant incentives.

However, the project continues to evolve through better governance, technical upgrades, and improved reward mechanisms to address these issues.

The Future of Helium and Decentralized Networks

Helium represents the beginning of a broader movement toward decentralized physical infrastructure. Its success demonstrates how blockchain can coordinate large-scale, real-world networks through economic incentives rather than centralized control.

As the network expands into 5G and other wireless technologies, Helium has the potential to disrupt the telecommunications industry by offering an open, community-driven alternative.

The rise of the DePIN model-of which Helium is a pioneer-signals a shift toward distributed ownership of essential infrastructure. In the future, we may see decentralized networks powering everything from internet access to energy grids and transportation systems.
