The Decentralized Wireless Alliance governs and maintains the Helium Blockchain and LongFi technologies.
Built from the ground up, the Helium blockchain powers the network and serves as the underlying technology for Helium tokens (HNT).
The blockchain acts as a ‘cryptographic notary‘ since transaction data from devices including connectivity time, and the location is added to the blockchain and is immutable, inspectable, and censor-resistant.
What is Proof-of-Coverage?
Proof-of-Coverage is a unique work algorithm that uses radio waves to validate Hotspots are providing legitimate wireless coverage.
For this validation work Hotspots can earn Helium tokens by verifying network transactions, adding new blocks to the blockchain, and performing other tasks. To participate in PoC, there must be multiple Hotspots at least 300 meters apart in an area, but still within range of each other (up to many miles depending on environment). Single Hotspots earn less as they can only issue Challenges over the internet, and can’t participate in Proof-of-Coverage.
Open Wireless Protocol
Helium LongFi combines the LoRaWAN wireless protocol with Helium Blockchain so any LoRaWAN device can transfer data on the Helium Network.
LongFi delivers roaming capabilities and supports micropayment transactions so customers only pay based on network usage without needing to deploy gateways or network servers.
Frictionless Device Onboarding
LongFi combined with the Helium blockchain allows a company to onboard as many devices as they need without additional configurations or third-party assistance.
During onboarding devices are mapped to a company ID on the blockchain, and become trusted by the network letting them connect and send data via any Hotspot.
LongFi allows owners to earn Helium when devices transfer data over the network through their Hotspots.
Any LoRaWAN device or sensor can transfer data over the largest public LoRaWAN network in the USA.
