Hard for me to overstate how cool this tech is and how much I want it to succeed.

With continued testing of our MVP and minting onchain location proofs our @optimism devnet we wanted to highlight two Beta Zones in San Diego, CA and Llano, TX ☀️ New localizers provide multiple user options based on the reception of the Zone 📶📍📡

Proof of Location. Use radio beacons instead of satellites to prove that someone was at a place at a time. People throughout a city can become ‘anchors’ by mounting a radio to the side of their building or on the roof. This network of radios provides location services that are…

Earlier this week we shared photos of the newest wireless mobile node for Proof of Location. 📸 We have been busy through the week checking on Zone maintenance and testing minting location proofs onchain with our @Optimism devnet! 🫧⛓️ 🔴

The FOAM team is grateful to the @Optimism badgeholders and proud to be recognized in RPGF3! 🔴 We are just getting started building on the OP stack and providing Proof of Location onchain and bringing #DePin the Superchain Exciting year ahead! Congrats all the recipients⛓️📡🫧

Hardware excellence

Evolution of the FOAM Mobile node for testing Proof of Location MVP📡 From a full sized Zone Anchor to a handheld wired node that requires a laptop 🧑‍💻 The 3rd current iteration is completely wireless in addition to being handheld being tested across Zones ⛓️🫧 #DePin

Some tech can be way ahead of their time. When I was working on my first project that utilizes blockchain technology for transport based solutions I stumbled upon @foamspace this was like 2021 Now the narrative for DePin is becoming a thing and these guys have been building…

6/ 📍 @foamspace Introduces OP Stack-Powered Proof of Location.

PSA: Be aware of Telegram scams related to FOAM. Any official announcements will be made on this account

Proof of presence with something like @foamspace

GPS if you trust that you won't have someone motivated enough to spoof their gps coordinates (which is pretty trivial, it's device-reported). if you can't trust gps, maybe @foamspace will work for you

2023 is quickly coming to a close, but not without one final weekly recap. Read on to learn how projects across the ecosystem are finishing up the year.

FOAM MVP: Presence Claim User Flow Demo 📡⛓️ This post covers hardware, software and current the Proof of Location user-flow for checking in with the FOAM network to mint Presence Claims 🫧📍

Now is an excellent time to be diving into FOAM and Proof-of-Location

Recovering an Ethereum Address from Radio Transmissions 📡⛓️📥 Technical Dive on how FOAM Radios send transmissions over the air that can be decoded and put onchain by smart contracts. Ethereum transactions are executed over radio 🫧

FOAM MVP: You Were Detected By a Zone! 👀✅ We are very excited to share that the front end and back end work is complete for the mining of Presence Claims on our @optimismFND devnet! #DePin Read more below on this Proof of Location development 🫧

DePIN: this one is the most fun! I talked about OG projects like @Livepeer , @foamspace , and @helium and newer ones like @Hivemapper and @teleportxyz that allow ordinary people to create value on decentralized networks. Expanding upon what I wrote here:

DePIN is actually a really cool category. There's just something neat about connecting the tangible with blockchain.

Something’s bubbling over at @foamspace . Learn more about proof of location smart contracts, deployed on their self-hosted OP Chain.

Recap on the Three Core Smart Contracts powering the FOAM MVP on our OP Stack devnet. ⛓️ First is the `Zone` contract, used to create and destroy Zones, and a registry of Zone Anchors that need to stake FOAM to be eligible to vote on Presence Claim validations and earn fees.

That’s wrap! 🎉 A heartfelt thank you to everyone who joined us at Devconnect x NYC and contributed to making this event a resounding success. We’re glad to have been able to offer an alternative space and experience as a satellite event for @EFDevconnect , here in New York…

We’re excited to welcome you to Devconnect x NYC! 🎊🥳 Join us for drinks + brunch at the icebreakers and networking that’s happening right now, and then get ready for amazing panels! Special thanks to our sponsors: @foamspace , @OPCryptoVC , @Neonrabbitsnft , and @jessepollak !🙌

Congratulations to @farcaster_xyz for going permissionless on @optimismFND ⛓️ Sign up today and follow @foamspace there for more updates 🫧

@foamspace added onchain contracts to their devnet and a UI for requesting and minting Presence Claims to their Proof of Location technology.

photo metadata + @foamspace proof of location + onchain attestation directly from the moment the pic was snapped could possibly solve a lot of verification problems of what’s real or not in times of conflict thinking out loud

Autumn 🍂 season underway with Zone Maintenance and additional Anchors being deployed across Zones ⛓️📡 #ProofOfLocation #DePIN

*cough* @foamspace *cough*

We are excited to have a Zone deployed with the Mycelium team in their Testbed in Arkansas for Proof of Location alongside many innovative projects! ⛓️🫧📡 The Mycelium Testbed offers great opportunities for testing use cases and will be a core Zone testing our onchain mvp 🎉

Announcing the completion of a @foamspace Trust Zone in the Mycelium Testbed. The team has been assembling, deploying, and testing the zone. Mycelium is thrilled to be included in the recently announced launch of the FOAM Testnet.
