Ico Review Ico Review – Open Protocol for Proof of Location on Ethereum

About is committed to solving this need by providing spatial protocols, standards, and applications that offer a higher level of security and resiliency than conventional geospatial technologies and location-based services. Location-based services have augmented both urban and rural life, changing how people get around and how products get to people.

In the future, the world’s collective critical infrastructure will rely even more heavily on spatial information, from stock exchanges to autonomous vehicles and the internet of things. have emerged to enable cryptographically secure transactions and distribute risks through peer to peer networks without the need for a trusted third party. Blockchains have the potential to enable secure and self-regulating emergent infrastructures of the future. New applications driven by smart contracts will need consensus-driven geospatial data that can be verified and trusted.

Previous attempts to create an open source map that is legible to humans, verifiable, and readable by machines, have been crippled due to a lack of funding for open source projects. This document explains how the FOAM protocol allows a grassroots user base to efficiently solve this infrastrucutre development problem around open communication

The Game Change Team Behind Ico Review - Open Protocol for Proof of Location on Ethereum

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. 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.[1] Maps and addressing systems are at the foundation of lives, and have played a major role throughout history. From the earliest forms of navigation, cartographers’ work has been a vital tool upon which commerce and development rely. have gone from hand drawn maps and non-standardized measurement tools like footsteps, to centralized cartography projects of ordnance surveys, to the most recent high-tech developments in digital cartography that rely on the work done by satellite imaging, geographic information systems and even street.

User Experience

Examples of such interfaces exist for centralized geospatial data sets, which are not compatible with open blockchain infrastructure. 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. Additionally, there are no open user experience standards for visualizing geospatial data from a blockchain. Numerous blockchain projects’ use cases have or will need visual mapping tools for smart contracts such as:

◊ Supply Chain
◊ Energy Markets
◊ Real Estate
◊ Mobility
◊ Location-based games

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. 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 Vulnerabilities of GPS

GIPS has become a ubiquitous tool, recently dubbed as “The Technology That Envelops Cities — and Brains” by Alphabet’s Sidewalk Labs. What may not be immediately apparent, is that GPS technology works through time as much as it does space. Inside each satellite is a high-precision atomic clock, which sync regularly to master control stations on the ground. GPS receivers, common in today’s smart phones, must pick up time-stamped signal data from a minimum of four overhead satellites. By using time stamps to calculate the time of arrival, a receiver can calculate a triangulated position.

Crypto-Spatial Coordinates

The 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.

Proof of Location

Foam is a shared and open protocol that is not rent seeking and does not charge or receive any centralized fees. Location is a fundamental infrastructure protocol needed to achieve the full vision of a decentralized ‘web3’ economy and can foster an ecosystem of applications built on top of a verified location standard. Proof of Location is the primary utility arising from use of the CSC and SIV elements discussed above. Proof of Location will inherently be an iterative process which involves the use of token curated registries by users to contribute, verify and determine Proofs of Location.
