2) Security. All it takes is one point of entry to be compromised for the entire IoT network to be hacked. This means the engineering of these smart devices has to be pristine, and that takes time.

2) Security.

4) Closed ecosystems. Many of the largest IoT players are large enterprises (e.g. Cisco, GE, Microsoft), and they all operate in closed ecosystems. There are no shared protocols defined for how devices connect both to each other and to a central hub. Consider: if a consumer buys two Google smart devices, three GE smart devices, and two Apple smart devices, without shared standards, these devices cannot communicate with each other.

4) Closed ecosystems.

5) Bad incentives. Consumers haven’t shown much interest in upgrading to smart devices because, frankly, the benefits do not outweigh the costs (i.e. low ROI). Enterprises have not made the effort to distribute and deploy these devices in the real world (high costs, unclear ROI).

5) Bad incentives.

Helium is a decentralized IoT network. The network consists of “hotspots” (devices) that are maintained by “miners” all around the world. These miners earn incentives for maintaining this network of hotspots, and the hotspots communicate and coordinate to provide data services for end users. The network is designed to be decentralized, the rules for orchestration and data services are hard-coded into smart contracts that live on Helium’s blockchain.Helium's algorithm,“Proof-of-Coverage”,  incentivizes the creation of this physically decentralized wireless IoT network.

At any point in time, a hotspot can play three different roles:<ol><li>Challenger: The hotspot that constructs and issues a “challenge.” Hotspots issue challenges approximately once per every 240 blocks.</li><li>Challengee: This hotspot is the target of the challenge. When it receives a challenge, it transmits the challenge response packets that nearby hotspots can listen to.</li><li>Witness: These are hotspots that are geographically close to the challengee and are responsible for “witnessing” the packets that the challengee is transmitting in response to the challenger.</li></ol>

7) Asset Tracking : Digital Matter is using Helium to provide GPS tracking devices for businesses that want to protect and recover assets.8) Air Quality Monitoring : Airly uses Helium to track air quality around the globe to help identify concentrations of dangerous airborne emissions.

4) Building & Asset Monitoring : Conserv offers wireless monitoring for art collections in private and public museums and uses Helium to provide information about artwork.5) Health Monitoring : Careband offers consumers wireless wristbands to monitor the location and temperature of people working in hospital or office environments to help track contacts related to COVID-19. Careband uses Helium to track the locations of wristbands.6) IoT Innovation : To minimize friction, Salesforce is using Helium to build an IoT program to allow employees access to these resources using their badges.

Part of the problem stems from hype and sensationalism in tech journalism. Journalists are storytellers, not technology experts. While they did their job of writing stories that drove people’s imagination wild, their narratives were a bit overexaggerated.

1) Sensationalism in journalism.

3) Privacy. We are all well aware of the privacy concerns of devices that track us 24/7. There are ethical concerns of whether the excessive amount of tracking that IoT would enable is a good thing or not.

3) Privacy.

1) Water Tracking - ReadyRefresh by Nestlé is a customizable beverage delivery service, and was one of the first customers to test the Helium network for water tracking in Connecticut.2) Agricultural Monitoring - Agulus is an agtech company and uses Helium’s network to automate water distribution based on wireless sensors connecting to the Helium hotspots.3) Micro-mobility tracking : Lime (the scooter company) uses the Helium network to find lost bikes and scooters.

cases for which Helium is being used today

We might have some sunshine in the IoT sector with the upcoming decentralised companies or even DAOs.

Remember when the “Internet of Things” (IoT) was all the rage? The concept was simple: we would put sensors on every physical object imaginable, turning objects from “dumb” to “smart.” But here we are in 2021, still waiting for the IoT revolution to happen. Could Helium be the blockchain that makes this pipe dream a reality?
