The validation of your address will be recorded anonymously on the Platin blockchain to prevent a user from repeating this claiming process each time he has to prove his location. Crypto-cartographers hope to use it for spatial verificationconfirming that things are where they say they are, when they claim to be there. If the crypto-cartographers have their way, those communities could be down-voted into oblivion. As a signed-in user you can create content, become a member of a community, receive notifications on your favourite solutions and topics, and access all other features available on the platform. The Witness earns less if the number of Hotspots in the area of the Transmitter exceeds the According to PoL upstart Foam, Civil GPS is unencrypted, it has no proof-of-origin or authentication features, and despite dire warnings first raised in 2012, the system remains extremely susceptible to fraud, spoofing, jamming, and cyberattack., The cartographer and historian of science Bill Rankin finds some of these critiques a bit overstated. Bitcoin has crashed more than 75 percent since its peak, and its competitors are faring no better. The Challenger, after the poc_timeout number of blocks, will create a blockchain_txn_poc_receipts_v2 The ultimate power of Proof-of-Coverage lies in the fact that the data In cities, for example, evangelists have promised an array of blockchain urbanism innovations. This includes further work on standards, interoperability and an enabling policy environment. Besides that, GPS has some other limitations: It requires at least four beacon signals to be overhead, which makes indoor localization nearly impossible. capacity needs of the network. Similarly, Light Hotspots themselves, if they determine the message received from a Validator is

They do this reliably Regarding interoperability, it is argued to be essential to the success of blockchain in enabling digital government. Implementing Platins Proof of Location is the solution to this problem.
It was emphasised that a range of public and private services require users or devices to demonstrate their location to access them or for the service to work properly. The "challenge" is the discrete unit of work for Proof of Coverage. Blockchain is also backing a new mode of mapping. A beacon is a single transmission witnessed by any Hotspot. Vehicle navigation and traffic redirection has improved as a result of this as well. Foam also builds on the biases of its precursors, including GPS. eeded reliable and timely data on the maintenance of records related to animals health and treatment and data associated with product production. Platin nodes use ZKP to achieve similar blinding regarding location information. Foams protocol is open source. The set of agreed on public keys hashes will then be deterministically truncated (in case there are The third section tackled the concept of proof of location (see definition above.) As mentioned, it was emphasised that there is a need for continued support to the development, uptake and dissemination of commonly agreed-upon standards for blockchain and distributed ledger technologies. Blockchain can be used to support decentralised and privacy-friendly proof of location services attesting to someone or somethings presence at a certain geographic location at a certain time. The public key hash will be used with the block The Light Hotspot then uses this routing information to directly submit the Witness Let's take a look at how challenges Copyright 2017-2022 crypto.bi - ELI5 Cryptocurrency guides, tutorials for beginners material. as a PoC Challenge. Further, for a device, it can take multiple minutes to acquire an accurate coordinate. Each Consensus Group member will deterministically select a certain number of keys from Nonetheless, Platins Proof of Location protocol offers many possibilities for future use cases like commercial GEO airdrops (see video below). ELISE - European Location Interoperability Solutions for e-Government. Well, you could know precisely when an Amazon delivery drone drops a package on your doorstep, at which point the charge would post to your account. There is a growing need for secure track and trace systems that can proof each location of the end product. The two differ in interoperability as wellbasically, Platin, which is the only hardware agnostic proof of location protocol, can use FOAMs curated data and beacons, as well as Bluetooth beacons and any other sensor data, since Platin uses Sensor Fusion. For the Transmitters, the more witnesses, the more the Transmitter earns; For the Witness, each additional witness past a total of four reduces what is earned by each Validators can create a challenge request every block, but a chain variable poc_challenge_rate receipt to the Challenger. The Witnessing Hotspot uses Each block is chained to the previous block and immutably recorded across a peer-to-peer network, using cryptographic trust and assurance mechanisms[1]. More elaborate ZKP applications can prove that a node met all the conditions of a contract, without revealing anything else. Its not that we distrust existing geolocation tools, however, we can ask the opposite, why would we trust it? determines how many Challenge requests are allowed in a block. POC-related data. As this number increases, more Platinum breaks down that barrier by giving digital assets a real, fixed location on a map. Platin is an innovative project that was born in Israel, one of the biggest innovation hubs in the world, especially in the blockchain sector. Light Hotspots submit their Witness report over gRPC. Probably, you are familiar with the game Pokemon Go where children (and adults) made use of geolocation spoofers in order to play Pokemon Go in cities like Melbourne or New York where you could catch Pokemons anywhere around you. The proof-of-location (PoL) protocol uses this approach for spatial verification. Blockchain could be the preferred option for location-based public services when there is a particular need for security and transparency. This can only happen by continued support to the development, uptake and dissemination of commonly agreed-upon standards for blockchain and distributed ledger technologies. In Ireland, the regulator for agri-food n hash to generate entropy to generate an H3 region for the Challenge. During absorb of a heartbeat txn, if the proposed keys do not belong to a Can it be trusted? Banks and other financial institutions need to follow strict KYC and AML guidelines. If you are interested in knowing more about ELISE Webinars you can find further informationhere. the wireless coverage provided by Hotspots on the Network.
As stated by Roberto Viola, Director-General, DG CONNECT: Europes ambition is to set the gold standard for blockchain technologies. Platin is beginning to build relationships with relief organizations like IsraAID and the Swiss Red Cross to create simple decentralized donation systems. Blockchain-based mapping hopes to replace GPS. Concerning digital transformation and innovation, blockchain technology is recognised by the European Commission as one of the key emerging technologies that are shaping the future. #13- Apple CarPlay Not Working? As Rankin explains, the creators of GPS saw it as a utility that turned location into a commodity available in much the same way as electricity or water. For Rankin, that design has political implications: It substitutes a locally available grid of geographic coordinates for other kinds of local knowledge, such as folklore, vernacular histories, or habitual experience, he says. Smart contracts are agreements between two people in the form of computer code that runs on the blockchain. However, such utility bills can be easily spoofed. While FOAM will have to wait for curated beacons to begin operation, Platin can be used without any such deployments. When four or more proximate beacons (Foam calls them anchors) form a zone, they can synchronize with one another to determine the position of objects. The advantage of a fixed If a beacon has been configured at that location, the smart contract will detect this and reward the user.

creating from that location. As of HIP 15, Proof of Any Light Hotspot hearing the transmitted packet will serve as a Witness as we have today on the We tend to identify places using postal codes or latitude/longitude, and the internet has given us an amazing amount of information to help us find where we need to go. There is no need for users to meet or trust each other in a geomining operation. per block. that reward pool. This is a very useful way of sharing information without disclosing the actual information and is employed in other blockchains such as ZCash, where senders, recipients and transaction amounts can be completely blinded. But not all community forces are positive; they also include NIMBY-ism and entrenched patterns of racism, classism, and other biases. He told me that governance is built into the protocol (unlike with GPS). the Validator(s) they are connected to as a client to lookup the Challenger Validator by the hash of What is blockchain, why it matters & fields of applications? Who knows how spaces such as informal infrastructures, indigenous terrains, and the leftover spaces that shelter the marginalized would fare in a crypto-map? In traditional systems, a user has to upload a utility bill to prove he physically lives at a location. In so doing, GPS encourages intervention without long-term commitment. PoL could similarly incentivize location miners to find collective value in the growth of the network, as King proposed to me, framing growth and network effects as civic values. included in Validator heartbeat txns whilst the private key will be saved to local state on the Each Validator will generate a set of ephemeral key pairs and a hash of the public keys will be Nowadays, consumers are very skeptical about where their food is coming from.
Others are more modest, applying the blockchain to urban inefficiencies in planning, zoning, building performance, and energy trading. RF has limited physical propagation and, therefore, distance; The strength of a received RF signal is inversely proportional to the square of the distance from We propose a fixed The protocol promotes other rewards, too. GPS works using the same general method, but it allows only for one-way communication; Foams PoL protocol allows users to send messages back to the system, which confirms the location via verifiers and saves it on the blockchain, King told me. such, it required a work algorithm that was built for this use case. Use cases within mobility, IoT, supply chain and location intelligence were touched upon. In addition, the whole Platin concept is GDPR compliant. Any security specialist can tell you that these strings of numbers and letters can be connected to particular individuals after just a bit of detective work. A bank can airdrop some PTN coins at a physical location the user has to claim within a fixed timeframe for secure verification of physical presence. Target density varies by hex resolution, as detailed in the HIP and defined in Proof of Authority (PoA) Summary [Cryptocurrency consensus mechanisms], Proof of Space (PoSpace) Summary [Cryptocurrency consensus mechanisms], Proof of Space Time (PoST) Summary [Cryptocurrency consensus mechanisms], Proof of Capacity (PoC) Summary [Cryptocurrency consensus mechanisms], Proof of Work vs Proof of Stake: Basic Mining Guide, Proof of Activity (PoA) Summary [Cryptocurrency consensus mechanisms]. Yet these words Zero Knowledge Proofs were chosen quite carefully by the mathematicians who crafted these amazing, almost magical acts of secure, privacy-preserving communication. Put another way, PoC tries to verify, on an ongoing basis, Typical obfuscation methods just arent enough. Lets take a look at a legacy protocol in another area: geography. It also says how to end the communication.
actually happen. Location is meant to be commercialized: The platforms hope to foster an ecosystem of applications built on top of a verified location standard, as Foam puts it. How might this be useful? locally on the Challenger Validator. HIP17, With regards to location-enabled services, this solution can, for example, be impactful for supply chain and land registry solutions. The commercial maps data are proprietary, and their plotted features sometimes fail to reflect rapid changes in real space. to earn the portion of HNT rewards allocated to challengers. Property boundaries, historically marked by degradable and movable thingsstakes and streams, fence posts and handshakesare often contested, and land areas are sometimes miscalculated because of accumulated historical errors in measurement. All you need is a smartphone to reveal whats right there. attested. Selected A range of European policies and initiatives are supporting the uptake of blockchain at the European level. #12- What is One Hot Encoding? You must have JavaScript enabled to use this form.
As part of the webinar, guest speakers from FOAM[6] joined to speak about their business model based on proof of location on the blockchain. Even if the bubble has burst on non-fiat currency, the technology underlying those coins, the blockchainwhich offers a way to record and validate transactions without a central authority, such as a bank or governmentstill excites many speculators outside finance. Transfi Protocol is adopting the proof of location model to improve on the functionality in the transport sector. Upon handling a block, each Validator will inspect the public keys in the block, identify any of A protocol is a set of rules in which computers communicate with each other. This webinar explored the concept of blockchain and proof of location as supporting digital government and location-enabled public services. Proof of location is defined as a digital certificate that attests someones presence at a certain geographic location, at a certain time[2]. These companies collect and sell our precious location data in order to finetune their ads. The attestation provides evidence on behalf of the Light That could have material effectsperhaps even gentrification and displacementin real life. witnessing a packet scale depending on two things: The HIPs themselves provide a rich explanation of these mechanisms, so you're encouraged to read You could also submit a photo of your flooded basement or smashed windshield to your insurance company, supplementing your claim with time- and location-verified documentation. those, but they can be summarized as follows: All messages originating from a Validator containing an assertion about the blockchain will be This includes messages not described in this document. Part of the power of Platins protocol is based on its use of zero knowledge proofs. Platin users can even earn money when sharing their data with large data companies while maintaining the control over their data. Moreover, by leveraging a smart contract functionality, validation rules were defined to assess data inputs accuracy and reliability into the platform. In a geomining application, users earn rewards for being at a certain place at a certain time.
Nevertheless, ongoing developments show clear value for citizens, businesses and public authorities. The proof of location can be a relevant feature for smart contracts solutions. For example, a node can prove that it is within a large region, say the state of California, without sharing its actual location. This avoids the need for periodic changes to poc_challenge_interval We have implemented a strong regulatory and policy framework that supports sustainable blockchain innovation as well as the start-up and scaleup ecosystems. their own keys, and for each, initiate a new PoC. Hotspots are located where they claim. Todays geolocation tools cannot offer reliable and trusted location verification services. Entropy from a combination of Coverage relies entirely on beaconing. As a case study, a track and trace solution developed by Deloitte was presented. as we do today in order to reduce load on the network. Our internet is being abused by large data companies like Google, Apple, Facebook, and Amazon. and Foam claims that it focuses on objective spatial information, yet it seems to see spatial value in economic or reputational terms. That could lead users to stake their tokens to map readily verifiable, predictable features and high-quality neighborhoods and facilities (that is, those with a strong reputation for good schools, low crime, and high property values). You-re welcome to join the team to build the future of Transport system. Check out the recording and supporting slidesfor the webinar Blockchain and proof of location supporting digital government. Understanding Witnesses and Relayed Hotspots, to earn the portion of HNT rewards allocated to challengers, Challenge Proof Construction and Target Selection. ELI5 - Explain Cryptocurrency Like I'm 5! succeeded at a challenge during the epoch and each of them also earned a "reward unit", then each Hotspot gets 1/6th of the 5.31% of rewards in that epoch. Contributors can stake their Foam tokens to create lists of points of interest (POIs), such as coffee shops with Wi-Fi, the best dog parks, urban landmarks, or government facilities. Other token holders can then vote on those lists; up-votes increase the value of the list and the value of the list creators tokens. Thats why Platin uses Zero Knowledge Proof (ZKP) technology to convey location details in the form of tamper-proof credentials. keys will be removed from the poc_key_proposals cache. If, for example, a company wished to gather participants for a promotion, at a specific physical store or shopping mall, they could launch a geomining task to reward participants who attended the event. Hotspot might earn a "reward unit" for succeeding at a challenge. One of the criteria is validating the location of the user. The protocol says what part of the conversation comes at which time and prescribes the format of the communication. Smart contracts are launched by interested parties and users simply need to attend geographic locations in order to interact with the smart contract. visualize how this works: The Helium Network is a physical wireless network that succeeds based Efforts are being made in this field, notably by the OGC Division Working Group on Blockchain and Distributed Ledger Technologies[4] and the ISO Technical Committee on Blockchain and Distributed Ledger Technologies[5]. Platins whitepaper goes into details about how their software security will work, and they have announced a new Zero Knowledge proof at the recent TechCrunch in Zug. If the Challenger Validator member determines the instruction/data was spurious in nature, This kind of algorithm is usually employed in cryptocurrency geomining systems. untrustworthy, can build their own untrusted list of Validators. Foam plans to create incentives for operators to build low-power, wide-area networks composed of radio beacons that can access the unlicensed radio spectrum. blockchain records more data about the quality of the network. Urban density and skyscrapers also cause difficulties in receiving four messages and the issue of multi-path signals occurs within the vicinity of high rise buildings. What makes a quality list of places in the world? Even so, users can also use their tokens to signal where location services are needed and to inspire growth in underserved areas. Most people are not aware of how many different protocols they are using. The Geon project, for example, uses Geomining to reward users who get close to a Geon, which is a virtual beacon that rewards Geon Coins to participants who get close enough to a specified geographic location. When it comes to power consumption, GPS is a drain on the battery and is not feasible for low powered Internet of Things (IoT) devices.
unsolicited, or otherwise untrustworthy then the member can decide to act on this. And GPS, some critics say, is poorly suited for use in dense urban environments and indoors, drains cellphone batteries, and is centralized (a big downside for blockchain advocates). For every epoch, each reward type is split amongst Hotspots who had a role in
and selects (up to) 25 of those valid to write to the chain. Specifically, PoC relies on the following Hotspot to the Challenger Validator that it received the instruction and/or data that resulted in Donors can easily drop coins in geo-fenced locations and those in need can collect the cryptocurrency and put it straight into their digital wallet. Using a Proof of Location protocol on their own blockchain, called the Plexus, Platin makes it simple to verify a location claim. generated by the ongoing proofs and stored in the Helium blockchain is definitive verification of Cryptocurrencies have had a rough year. changed through governance and can be adjusted based on the ability for Validators to serve the Virtual assets with a real spatial location become so real, you can collect them by holding out your device. Money was blockchains first target, but in theory, any type of agreement that currently requires a middleman could be managed with blockchain technology insteadno lawyer, notary, bookie, or referee needed, as The New Yorkers Nick Paumgarten puts it. A technical definition of Zero Knowledge Proofs reads in short, A Zero Knowledge Proof (ZKP) is a method by which one party (the prover) can prove to another party (the verifier) that she knows a value X, without revealing the value itself.. The webinar showed two roles of blockchain in the location domain, namely proof of location and the use of location data for other blockchain-enabled applications and services. Using SolidityGEO smart contracts can handle map, place and region data with capabilities to store it, curate stakes associated with places, express consensus around this data and so on, in various levels of precision. Whats more, the Foam network is pretty hard to jam, and it requires less power than GPS does. 5.31% of rewards that go to PoC Transmitters. [1] ALLESSIE D, SOBOLEWSKI M, VACCARI L, PIGNATELLI F (Editor), Blockchain for digital government, EUR 29677 EN, Publications Office of the European Union, Luxembourg, 2019, ISBN 978-92-76- 00581-0, doi:10.2760/942739, JRC115049. These examples are certainly appealing. For example, the EC Blockchain Strategy, European Blockchain Services Infrastructure[3]. several chain variables. They can provide increased certainty, transparency and automation in transactional public services. Zone operators both stake and receive tokens as they perform their geolocative labors. Crowdsourced tools such as OpenStreetMap are dogged by problems: insufficient funding, confusing usage policies, the failure to create incentives for contributors, and difficulty with accuracy. This ability to present digital assets in a simple and clear way has many potential benefits. The Helium Network Explorer is the best resources for viewing A change made with the 2021.09.14.0 release randomly shuffles the valid received witness receipts, To date, there have been 10s of It was also explained that proof of location could be added as a condition in the contract code. The idea is that proving that you are at a certain location, at a certain time, using a trusted location tracking device, can signal value to some cryptocurrency networks. Katya Zavyalova (CCO) and Ryan King (CEO) explained that FOAM is working to provide a location service that provides secure and ubiquitous location information through blockchain. This is a very innocent example, although, GPS spoofing can be used in far more dangerous cases like spoofing the location of an ambulance which can cause the death of a certain person.
request to that Challenger Validator. GPS devices allow extremely fine location services which were only available to the military a couple decades ago, giving rise to people geocaching and exploring new terrain. And crypto is just one type of digital assetdigital documents are another. Of course, we already have tools for geographic verificationGoogle Maps, Foursquare, OpenStreetMap, and the state-backed Global Positioning System (GPS) they rely on. According to the CEO, Ryan John King, Zone operators on the Foam network are in essence providing comparable work to Bitcoin miners.. Or, as you pass by your local family-owned coffee shop, the owner could airdrop some Bitcoin coupons to your phone, and you could stop by to cash in before the offer expires a half hour later. To have a full decentralized transport solution each protocol would have to work simultaneously. #10- The Best Online Platforms to Learn Something New, Today! challenges will appear on the network. Their protocol is lightweight and safe, consuming very little energy making it ideal for many diverse use cases. Validator's attestation, to allow for slashing of the Validator's stake. If five additional Hotspots Voting for points of interest hardly guarantees that they will serve the public well. These three words seem to contradict one another. If a Light Hotspot receives a message from a Validator and needs to act on it (e.g., contacting a Administrations across Europe play a trailblazing role in implementing this exciting and essential new technology.[7]. The device notifies an oracle that the user has been present at a certain location at a certain time. generating Validator. the said action. Other key features of FOAM location is their open-source standard ensuring there is no central point of failure, a tamper-resistant way of sharing location data and providing presence claims through digital certificates that are fraud-proof. Challenger Validator to submit receipts) the Light Hotspot will include the attestation in its transaction, using received Challengee receipts and Witness reports, and submit it to the blockchain PoC Challenges involve three distinct roles: (Note: The goal is to reduce the PoC Interval to 200 blocks or lower). Proving a fact must require knowledge, and certainly more than a zero amount. However, these credentials can be verified for authenticity, making them a much more secure way of determining location. A bet on an up-and-coming area determines users spatial-mining rewardsthe bounty doled out, in this case, for extending the map to underrepresented regions. The region, challenge, and target will be persisted minimum of 2f+1 nodes participating in a block, we are able to reach poc_challenge_rate if each But the physical world might not be as easy to map as crypto-cartographers believe. Continued technical and strategic work is required to support the uptake of blockchain in the public sector. Overall, there is far more fluidity in matters of physical boundaries and access than blockchain allows. The architectural setup of blockchain applications such as proof of location and smart contracts can increase trust and security.
