Platin is a lightweight, secure and verifiable Proof of Location (PoL) protocol on the blockchain
Platin is a lightweight, secure and verifiable Proof of Location (PoL) protocol on the blockchain based on three primary pillars:
Locations around the world are continuously scanned by nodes for diverse signals detectable by a smartphone, verifying and updating the oracle's canonical data.
Signal histories of nodes are sampled periodically and applied to increase a node's trust score. The longer and more diverse the accumulated history and the richer the signal spectrum, the more PTN can be mined for witnessing a PoL claim request from neighboring nodes.
Peers exchange data, analyzing and mutually comparing it to vote on honest nodes and thwart sybil attacks. Using gossip protocols and zero knowledge proofs trust flows from high to low enabling even new peers to participate in consensus and earn Platin currency (PTN) via Proof of Location.
Platin's three pillars of PoL provide a secure and robust PoL protocol while directly incentivizingparticipating nodes.
Air Drops (Humanitarian)
The commercial airdrop of cryptocurrencies at select locations incentivizes population movement while also providing an innovative way to acquire direct human traffic.
The negligible amount of friction caused when deploying Platin combined with its powerful incentives makes for an enduring use case on Platin's stackable secure location protocol.
Financial and other institutions under KYC & AML restrictions can create single-use, individual airdrops to be claimed within a fixed timeframe for secure verification of physical presence.
Users complete secure address KYC based on Platins' PoL without having to upload easily spoofable utility bills.
Every product has a story, as they have materials sourced in one location, assembled in another, and sold in still another. The location is a critical piece of information enabling trust of manufacturers, distributers and consumers to know the provenance of every component.
Certification, governance, audits and fair trade require this information as well. Platin proof of location is the simple way to solve this problem without middlemen.
Anyone with the Platin Pocket™ app on their smartphone can collect simply by exercising. Once they run or walk along the app's predetermined route during their workout, they will see and earn Platin coin.
Integration with popular fitness reporting on social media means that other cryptocurrency and exercise enthusiasts will see the Platin drop and join in to earn more.
The natural, ongoing movement of people enables anyone with a smartphone to passively and anonymously (using zero knowledge proofs) to witness peers and earn PTN coin while engaging with Platin's PoL protocol on the blockchain.
Platin's blockchain, the Plexus, enables:
High Throughput and Performance sufficient to scale quickly.
Low latency due its implementation of a lightweight and location-aware Ethereum fork with Platin's custom Solidity Geo
Scales to support thousands of transactions per second
Free for direct transactions, gas for geo-located transactions
Mobile-based computation: Early secure location recognition based on self-signed sensor fusion, with possible augmentation by means of local trusted beacons on the PlatiNet. These have an inherently high trust score and their attestations and witnessing of roaming nodes claiming a location, are treated with high confidence. Platin Pocket also enables wallet, airdrop, claiming, mining and standard send and receive functionality.
Each coin airdropped at a location on the map is enforced by a policy stating the terms for that coin. Policies are created via the Platin API and include claim radius & promiscuity, time limitations, wallet throttling, multi-node requirements, movement & behavior, transaction confirmations, authentication, and more.
Platin nodes can challenge one another with unique, one-off non-replayable queries using asymmetric cryptographic signatures and ZK Snarks. Cryptographically secured ZK allows mining of PTN and claiming money from a location without compromising privacy or revealing one's identity. Verify a node's identity without ever revealing their identity. Verify a node's location without ever revealing their location.

We are happy to share with you the latest version of the Platin White Paper (release candidate). This version of the White Paper introduces new research breakthroughs in Proof of Location (PoL) and incentivized witnessing on top of Platin's distributed secure location protocol while providing a general overview of the Platin architecture.
