Secure and Transparent Location Data

FOAM offers a resilient solution using an open network of terrestrial radios, ensuring location verification that is resilient against hacking and spoofing, critical for industries reliant on accurate spatial information. FOAM operates on the Ethereum blockchain, ensuring transparency and censorship resistance, which are crucial for maintaining the integrity of location data across various applications. The FOAM token empowers participants to govern the network, ensuring decisions are made in the best interest of the community.

A Field of Applications

FOAM's verified location data supports a diverse range of use-cases, including IoT networks, supply chain tracking, mobility services, insurance verification, and location intelligence. This versatility makes FOAM a cornerstone for emerging technologies requiring precise and trustworthy spatial information.

FOAM Map

As a community-driven initiative, FOAM Map serves as a decentralized registry of crowdsourced places. Cartographers worldwide contribute to building and verifying this map, ensuring accuracy and reliability through a community-led validation process.

FOAM Location and the Trust Zone Testnet

FOAM incentivizes the creation of a distributed network of radio beacons called Zone Anchors, which synchronize through a Byzantine Fault Tolerant protocol. These Zone Anchors form Zones that offer secure location services independently of centralized sources like GPS. Validators ensure the accuracy of location data, making FOAM Location a robust solution even in challenging environments.

The FOAM Location Testnet, starting with the Trust Zone program, allows participants to refine localization technologies in real-world scenarios. Zone Operators play a pivotal role in testing and improving FOAM Location's capabilities, earning rewards in FOAM tokens for their contributions.

Team Background

Ryan John King serves as the Co-founder and CEO of FOAM, bringing expertise in urban economic development, architecture, and blockchain technology. Kristoffer Josefsson, Co-founder and CTO, contributes as a senior full-stack blockchain developer, having been an early member of Consensys and a founding member of BlockApps. Katya Zavyalova, Co-founder and Creative Director, brings her award-winning architectural background and leadership recognized by the American Institute of Architects to FOAM's team.

Project Develpoment

Cycloid, unveiled two weeks ago at the Consensus Conference in Austin, TX, represents a breakthrough in blockchain technology by enabling Ethereum transactions over radio waves. Developed by FOAM, Cycloid serves as both a hardware wallet and a platform for Proof of Location. It features a custom PCB and enclosure, housing an STM32 microcontroller and LoRa radio, alongside navigation buttons and an OLED screen.

This device can sign Ethereum transactions offline, sending them via radio to compatible gateways for blockchain relay. Cycloid is designed for end-users seeking secure, offline transaction capabilities, further supported by the Cycloid Live desktop app for firmware updates and wallet management. Its extensible platform, written in Rust, opens doors for developers to create innovative applications integrating smart contracts with real-world interactions. FOAM is preparing to release developer units this summer, with interested parties invited to join the waitlist for early access.
