The XYO Network has four primary components, Sentinels, Bridges, Archivists, and Diviners. These four components enable geo-focused, consensus-building and trustless verification of location data. This means that when you write a smart contract that specifies for an object to appear at a specific XY-coordinate, if it appears there, you will know that it was at that location with absolute certainty. This is all done without risk of spoofing the location signaling device(s) verified by thousands of Sentinels in the XY Oracle Network with the longest Proof of Origin chain (thus yielding greater confidence in the heuristics).
Sentinel components are heuristic witnesses. They observe heuristics and vouch for the certainty and accuracy of the heuristic by producing temporal ledgers. The most important aspect of a Sentinel is that it produces ledgers that Diviners can be certain came from the same source by adding Proof of Origin to them.
Bridges are heuristic transcribers. They securely relay heuristic ledgers from Sentinels to Diviners. The most important aspect of a Bridge is that a Diviner can be sure that the heuristic ledgers that are received from a Bridge has not been altered in any way. The second most important aspect of a Bridge is that they add an additional Proof of Origin.
Archivist components store heuristics in a decentralized form with the goal of having all historical ledgers stored, but without that requirement. Even if some data is lost or becomes temporarily unavailable, the system continues to function, but just with reduced accuracy. Archivists also index ledgers so that they can return a string of ledger data if needed. Archivists store raw data only and get paid only for retrieval of the data. Storage is always free.
A Diviner answers a given question by analyzing historical data that has been stored by the XYO Network. To accomplish this, heuristics stored in the XYO Network must have a high level of Proof of Origin to measure the validity and accuracy of the heuristic by judging the witness based on its Proof of Origin. Given that the XYO Network is a trustless system, Diviners must be incentivized to provide honest analysis of heuristics. Unlike Sentinels and Bridges, Diviners use Proof of Work to add answers to the blockchain.
PROOF OF ORIGIN
In a trustless system, data may be lost, damaged, tampered with, or otherwise corrupted. Traditional Proof of Origin in a trustless system relies on a private key for signing transactions or contracts in a system. This works very well with the assumption that the node on the network that signs the data in question is physically and virtually secure. If the private key is compromised, then the ability to prove origin falters. Proof of Origin (Proof of Origin) is the key to verifying that ledgers flowing into the XYO Network are valid. A unique ID for source of data is not practical since it can be spoofed. private key signing is not practical since most parts of the XYO Network are difficult or impossible to physically secure, so the ability for a bad actor to steal a private key is too feasible. To solve this, XYO Network uses Transient Key Chaining. The benefit of this is that it is impossible to falsify the chain of origin for data.
In a trustless system, a witness node can either (through defect or corruption) produce false data. Invalid data can be detected and removed simply if it falls outside the allowed range for that heuristic. Valid but incorrect data (i.e. false data) is much more difficult to detect. Given that an untrusted source of data used to resolve a digital contract (an oracle) is not useful, we can substantially increase the certainty of the data provided by first establishing the existence of a bidirectional proof of location. The primary bidirectional location heuristic is proximity, since both parties can validate the occurrence and range of an interaction by cosigning the interaction. This allows for a zero-knowledge proof that the two nodes were in proximity of each other. This novel concept is called "Bound Witness," and the XYO Network introduces this possibility, for the first time ever, to the world. The implications of this will change a multitude of industries and the way we trade in the world.
The XYO Network natively integrates with the leading blockchain platforms of today, and its agnostic protocol enables integration with the blockchain technologies of tomorrow.
"The XYO Network is the world’s first XY-coordinate bridge between blockchain and the real world”
Arie TrouwFounder & Architect
The XYO Network enables developers to gain the power to interact with the real world as if it were an API.
Think of the XYO Network not as a blockchain application (i.e. like websites are to the internet), but as fully fledged blockchain protocol (i.e. like HTTP is to the internet).
Similar to blockchain platforms like Ethereum, EOS, omisego and others, the XY Oracle Network gives developers a platform to build decentralized location-reliant DApps.
The XYO Network works natively with the following smart contract platforms as well as other blockchain platforms with Turing-complete functionality.
All transactions running on the XYO Network require XY’s Utility Token: XYO
The XYO Network has a consumer-friendly Web App Interface, developer APIs, and software libraries that span popular smart contract languages (Solidity, Viper and more).
Via the XYO Network’s Web App, users can instantly submit queries to the XYO Network by specifying the public address of the object they wish to track (i.e. a vehicle, package, luggage and more).
Our objective is to provide blockchain developers with the ability to access real-world location data using whichever DApp platform they wish. Our current list of platforms we intend to support is listed below:

According to a recent study released by Comcast, more than 30% of Americans have had a package stolen from their porch or doorstep. As the market share of eCommerce continues to grow, this problem will only become more prevalent. By utilizing the XYO Network and XYO Tokens, companies like Amazon and UPS can offer, as a premium service, an independently confirmed ledger to track every step of a shipment’s progress, starting at the fulfillment center and ending with the package’s secure delivery within the customer’s home.DOWNLOAD USE CASE PDF
Medical errors are the third leading cause of death in the United States, according to a study released by Johns Hopkins School of Medicine. Many of these preventable deaths are a result of operational or record-keeping errors, including adverse drug interactions, improper medical records, and even unnecessary surgeries. By tying the XYO Network into the operational frameworks that are already in place, care providers can significantly reduce failures in communication and record keeping that result in patient injury and death.DOWNLOAD USE CASE PDF
The number one problem that rental car agencies face are logistical ones. Simple events such as the customer losing their keys results in millions upon millions of dollars in lost opportunity cost for car rental companies each year. XY has already implemented a pilot program with one of the largest US rental car agencies to help cut down on the number of keys that aren’t returned at major airports. By expanding the program to make use of the XY Oracle Network, the rental car company and its customers can reduce the number of lost keys.DOWNLOAD USE CASE PDF
Lost and mishandled luggage costed airlines $2.1 billion dollars in 2016, according to a study by SITA. While systems are improving, the complexities of air travel still result in millions of angry passengers with lost bags each year. The XYO Network has implemented a decentralized, trustless system for tracking and locating luggage. Its decentralized nature even allows airlines to utilize each other’s networks without compromising the airlines’ network security or needing to coordinate system updates - this means that if you’re at the United desk in Dallas, but your bag is at the Delta desk at SFO, the bag can still be instantly located by accessing the XYO Network Ledger.DOWNLOAD USE CASE PDF
Insurance for vehicles, modular homes, and other high-value, high-mobility objects can reimburse for theft, but can’t inherently assist in locating the original good. The insurance industry is also susceptible to fraud, especially in the case of insured items that are highly mobile. XY is already working with an insurance company that covers high value, high mobility goods to help them process claims and recover insured goods. Using the XYO Network, a decentralized and trustless location-based blockchain ledger, the company and its customers have access to an independently verifiable location history in the event of a claim.DOWNLOAD USE CASE PDF
In high security areas, it is essential to ensure that any authorized firearms are strictly controlled. Creating a system that is secure, reliable, and publicly accountable poses an operational challenge. A high-profile government security agency has contracted with XY to secure firearms in major transportation hubs throughout the United States. The use of XY’s existing technology saves the agency millions of dollars, and the decentralized nature of the blockchain creates a system that is both independently secure and publicly accountable.DOWNLOAD USE CASE PDF
