Introducing Cycloid: Ethereum Transactions Over Radio
Two weeks ago at the Consensus Conference in Austin, TX we debuted new hardware, Cycloid, which enables Ethereum transactions over radio. Cycloid is the first FOAM end user hardware device to be made available for sale and use for Proof of Location. This post will take a first look at the platform and provide a waitlist at the end for the first batch of developer units. FOAM @foamspace The FOAM team has arrived in Austin for @consensus2024 with new Mobile Node Hardware, Zone coverage and Pres...

Open MVP & Zone Expansions
Further progress has been made on the FOAM Proof of Location MVP! Our recent update post shared a demo of the MVP process for proving location onchain using on our mobile app and a prototype user device. Today, the FOAM team is excited to share additional features that have been added to our MVP, as well as exciting updates on the plug-and-play radio (”Zone Anchor”) and user device (”Mobile Node”). https://mirror.xyz/foamspace.eth/4F1n7zjzXpcocWD82wpzfd27Ul9qFRCrulwO8URx5WM A reminder that th...

FOAM Token Live on Optimism
In anticipation of the FOAM Proof of Location MVP launching onchain, the FOAM token is now live on the Optimism blockchain with incentivized liquidity pools on Velodrome. Users can now swap and use FOAM tokens taking advantage of low transaction costs on Ethereum Layer 2s, the first step of FOAM joining the Superchain. This post will cover the basic information about FOAM on Optimism. https://mirror.xyz/foamspace.eth/4F1n7zjzXpcocWD82wpzfd27Ul9qFRCrulwO8URx5WM What is the FOAM Optimism Token ...

FOAM MVP: Mobile Presence Claim Demo
Continuing our series of posts showcasing the FOAM MVP, we are excited to share a demo of proof of location on mobile! This demo also features the use of a miniaturized, wireless user device! Minting location proofs onchain with FOAM is now easier than ever. To reiterate from prior posts, the core objective of the FOAM MVP is to demonstrate onchain proofs of location, which we call “Presence Claims”. These are represented onchain as NFTs with metadata like the location coordinates of the user...

FOAM MVP: Presence Claim User Flow Demo
To continue our series on the FOAM MVP and to mark the end of a very productive 2023 for FOAM, we are excited to share an end-to-end demonstration of the current proof of location process! To reiterate from prior blog posts, the core objective of the FOAM MVP is to demonstrate proofs of location (”Presence Claims”). Recently, this has required developing new layers to our stack, such as our FOAM Devnet (OP Stack rollup), Proof of Location smart contracts, an indexing and publishing service an...

Recovering an Ethereum Address from Radio Transmissions
FOAM is a Proof of Location technology for applications needing secure location services. It enables a handshake between the location service providers and the user, proving the user’s location. Terrestrial radios and time-of-flight algorithms are used to perform localizations, and digital signatures ensure the location data cannot be spoofed. The system is completely independent of satellite-based location services like GPS. Our previous post, linked below, shared development progress on min...
