FOAM is building a Spatial Protocol for the Ethereum blockchain with Proof of Location.
FOAM is an open protocol for decentralized, geospatial data markets. The protocol is designed to empower users to build a consensus-driven map of the world that can be trusted for every application. As technology evolves and changes, maps need to change too. FOAM secures physical space on the blockchain, harnessing the power of Ethereum with a cryptographic software utility token used to provide computational work and verification to the network.
The component elements of the FOAM protocol are designed to provide spatial protocols, standards and applications that bring geospatial data to blockchains and empower a consensus-driven map of the world. Token mechanisms and cryptoeconomics underpin the elements of FOAM and empower the distributed users to coordinate and interact in a decentralized and permissionless fashion.
Currently, there are no established standards for embedded locations, physical addresses, or coordinates in smart contracts. Further, there is no open way to verify geospatial data. For smart contracts to remain interoperable, they need a shared language for them to reference and index the physical world. Additionally, location standards today are an unsolved problem.
Throughout history, there have been many ways of encoding physical locations into addresses — from longitude and latitude all the way to the more recent geohash. While autonomous car companies are racing for more accurate location data, the fact remains that most of the Earth’s surface lacks an address. According to the United Nations, 70% of the world is unaddressed, including more than half of the world’s sprawling urban developments.
Similar to a need for a location encoding standard, there also needs to be able to interact, visualize and reason about the data with an advanced user experience. Examples of such interfaces exist for centralized geospatial data sets, which are not compatible with open blockchain infrastructure. Additionally, there are no open user experience standards for visualizing geospatial data from a blockchain.
Currently there is no reliable and trusted location verification service. It is problematic to rely on GPS and it is not a viable tool when a smart contract needs to execute autonomously on spatial information. A backup for GPS is needed because it can be easily spoofed, jammed, or falsified. This means that there is currently no truly secure way to verify location in blockchain-based smart contracts or decentralized applications.
The FOAM Crypto-Spatial Coordinate (CSC) is a starting point for this shared location standard, allowing any smart contract to make an immutable claim to an address on the blockchain and a corresponding location on the map. Crypto-Spatial Coordinates are Ethereum smart contract addresses with corresponding addresses positioned in physical space that are verifiable both on- and off-chain.
This allows for physical addresses in the built environment to have a corresponding smart contract address that is accessible for decentralized applications. The protocol uses the geohash standard as a basis for this construction because of its conceptual and mathematical simplicity. Another benefit of the geohash standard is that it is in the public domain.
The CSC standard can be adopted by any smart contract to make a claim to, or reference, a location in the physical environment. If adopted across projects and use cases, the CSC allows smart contract transaction activities to take on a spatial dimension. The CSC can act as a reference point for spatial events that works for any kind of transaction on Ethereum or other Ethereum Virtual Machine compatible blockchain.
Since geohashes are intrinsically hierarchical, it also means that a contract referencing a building, and a contract referencing an IoT device located within that building, automatically have a spatial relationship.

First release of our vision for a spatial protocol and consensus driven map.
Release of Crypto-Spatial Coordinates, an open and interoperable standard for location in Ethereum smart contracts.
We started off 2018 by formally announcing the work being done at FOAM on Proof of Location and its fundamental importance.
Launched a private beta on the Rinkeby test network for The Spatial Index, a general purpose visual blockchain explorer.
As part of our developer community efforts, we released access to tools for building decentralized spatial applications, API access, sample tutorials and walkthroughs.
Opened the Spatial Index Beta to the public with over 2,500 users stress testing the architecture.
After months of fine-tuning and legal review, we were extremely excited and proud to publish our product whitepaper.
Tokens are distributed to all purchasers on the Ethereum MainNet.
Following the launch of the FOAM protocol tokens will not be transferable outside of the platform for 45 days. In this time users can familiarize themselves with the interface and fulfill their ‘Proof of Use’ requirements.
