Overview

FOAM is building a Spatial Protocol for the Ethereum blockchain with Proof of Location.

Project stage

Beta version

Detailed description

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.

Problem

Location Encoding
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.

User Experience
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.

Location Verification
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.

Solution

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.
