FOAM is an open protocol for proof of location on Ethereum. Our mission is to build a consensus driven map of the world, empowering a fully decentralized web3 economy with verifiable location data. FOAM incentivizes the infrastructure needed for privacy-preserving and fraud-proof location verification. The starting point for FOAM is static proof of location, where a community of Cartographers curate geographic Points of Interest on the FOAM map. Through global community-driven efforts, FOAM’s dynamic proof of location protocol will enable a permissionless and privacy-preserving network of radio beacons that is independent from external centralized sources and capable of providing secure location verification services. FOAM Token Functionality 1. Add and Curate Geographic Points of Interest The FOAM Spatial Index Visualizer allows Cartographers to participate in interactive TCR POIs on a map. Users can add points to the map, validate new candidates and verify the map by visiting real world locations. The FOAM Token Curated Registry unlocks mapping in a secure and permissionless fashion and allows locations to be ranked and maintained by token balances. Users can deposit FOAM Tokens into POIs on the map to increase attention those POIs might receive. 2. Signal for Zone Incentivisation A further potential use of the FOAM Token by Cartographers is to stake their FOAM Tokens to Signal. Signaling is a mechanism designed to allow Cartographers to incentivize the expansion and geographic coverage of the FOAM network. To Signal, a Cartographer stakes FOAM Tokens to a Signaling smart contract by reference to a particular area. These staked tokens serve as indicators of demand, and are proportionate to (i) the length of time staking (the earlier, the better), and (ii) the number of tokens staked (the less well-served areas, the better). In the context of the contingent Dynamic Proof of Location concept (described further in the Product Whitepaper), these indicators are the weighted references that determine the spatial mining rewards. 3. Contribute to Potential Secure Location Services as Zone Anchor or Verifier The FOAM protocol may allow users to provide work and secure localization services and location verification for smart contracts and be rewarded for their own efforts with new FOAM Tokens in the form of mining rewards. Devices and real world contracts can be programmed to designate attestations and track interactions and transactions on the map. With the addition of necessary radio hardware by individual users and the grass roots expansion of the FOAM network, it may be possible for location status to be proved in a different manner. Location could be proved through a time synchronization protocol that would ensure continuity of a distributed clock, whereby specialized hardware could synchronize nodes’ clocks over radio to provide location services in a given area. As explained further in the following paragraph, this ‘Dynamic Proof of Location’ is contingent on a number of factors outside of Foamspace’s control.
BITKAN as an App serving cryptocurrency users and integrating market, information, mining monitoring and wallet, it provides four language versions, namely Chinese, English, Russian and Japanese. Now it has more than 5 million users from 170 countries around the world. BITKAN provides quotations and candlestick charts of more than 2,200 kinds of cryptocurrencies from more than 50 major cryptocurrency exchanges around the world. It has achieved News cooperation with more than 70 international media. The daily news updates are over 300, and the daily reads of the News section are over 500 thousand. BITKAN provides wallet services for digital asset transfer, such as BTC, BCH, DASH, ETH, SAFE, and it has provided stable and secure wallet service for the assets of 170,000 users. The team will launch the first blockchain-concentrated community around the blockchain industry based on the BITKAN platform: K Site. The community will encourage users to produce high-quality contents, and users can get profits in the form of cryptocurrencies by publishing high-quality contents. The communities created by users in the community will be presented in the form of 'K Site'. The creators can set up the 'K Site' to pay for admission or join for free. By composing high-quality contents, it can attract other users to join in and form their own 'K Sites'. Users having joined in can read the contents of the 'circle' or post their own content in the 'circle'. On the other hand, users can also set a certain content for paid reading, the more people who read, the greater the income. Users can also reward the content to encourage the author to continue to compose more and better content. KAN will be used to pay for the platform services of BITKAN. If a user keeps sufficient amount of KAN will enjoy a certain percentage discount for service fees, and service fees will be deducted from KAN. The main project team comes from BITKAN, which currently provides price monitoring, news and information, mining monitoring, wallet and other services for cryptocurrencies. Users can store cryptocurrencies simply, conveniently and safely through the BITKAN app. At the same time, they can check the market price of cryptocurrencies of major exchanges in real time, get timely and fresh industry information at home and abroad, and set up price reminders by BITKAN app. And it has real-time mining monitoring, which allows you to master the running condition of the mining machine whenever and wherever possible. The token is called 'KAN'. A strict limit of 10 billion KAN will be issued, and will never be increased. KAN will be issued according to the Ethereum ERC 20 standard. KAN's profit comes mainly from the payment fees, exchange fees and membership service fees from the BITKAN platform. BITKAN is already online. The team is currently developing the 'K Site' feature which is a decentralized crytocurrency-concentrated & content payment community. KAN will be online as the same time as the 'K Site' feature, which is scheduled in May 2018.
