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.
Huobi, the third-largest cryptocurrency exchange in the world, recently announced and launched a new currency. The Huobi Token (HT) rewards exchange users for their loyalty with lowered transaction fees while also carrying its own value in tradable pairs against popular currencies. The hope was to bring greater value to Huobi’s millions of users, mostly located in Asian countries. The launch of the Huobi Token follows in the footsteps of other loyalty-building tokens that other exchanges have launched. The first and most successful of these tokens has been Binance Coin (BNB). The creation of BNB secured Binance’s place as the world’s leading exchange. It offered discounted trading fees in exchange for customer loyalty, primarily functioning as a loyalty rewards system. Huobi officially announced its intentions to launch a new token on January 22, 2018. Over the course of 15 days, Huobi would distribute 300 million HT (60% of the total supply) to its pro users who purchased a discounted service package. Each morning, a new batch of HT would become available on a first come, first served basis. Huobi declared this token distribution scheme, “not an ICO,” due to the nature of the offering. Users are buying a specific service package, part of which includes HT that give a discount toward trading fees. The exchange launched the Huobi Token as part of an overall strategy to recover its user base after tightening regulations in China severely restricted cryptocurrency trading. In an interview with CoinDesk, Leon Li, Huobi’s founder, revealed that Chinese rule changes had decimated the trading volume on Huobi by 95% between September 15 and November 1, 2017. The HT token distribution began on January 24 and wrapped up on February 7, 2018. Each day of the distribution, millions of tokens sold out in mere minutes after going on sale. At that point, 300 million HT had been distributed to Huobi Pro members who bought packages. That’s 60% of the total supply currently in public circulation. Another 200 million HT, 40% of the total supply, was set aside. 20% goes toward user rewards and platform operation. The other 20% is vested for four years and constitutes the team reward. Huobi isn’t the first exchange to issue its own token. Binance (BNB), Bibox (BIX), KuCoin (KCS) and Coss (COSS) have all issued their own tokens as well.
