Binance Coin is the cryptocurrency of the Binance platform. It is a trading platform exclusively for cryptocurrencies. The name 'Binance' is a combination of binary and finance. Thus, the startup name shows that only cryptocurrencies can be traded against each other. It is not possible to trade crypto currencies against Fiat. The platform achieved an enormous success within a very short time and is focused on worldwide market with Malta headquarters. The cryptocurrency currently has a daily trading volume of 1.5 billion - 2 billion US dollars and is still increasing. In total, there will only be 200 million BNBs. Binance uses the ERC20 token standard from Ethereum and has distributed it as follow: 50% sold on ICO, 40% to the team and 10% to Angel investors. The coin can be used to pay fees on Binance. These include trading fees, transaction fees, listing fees and others. Binance gives you a huge discount when fees are paid in BNB. The schedule of BNB fees discount is as follow: In the first year, 50% discount on all fees, second year 25% discount, third year 12.5% discount, fourth year 6.75 % discount, and from the fifth year onwards there is no discount. This structure is used to incentivize users to buy BNB and do trades within Binance. Binance announced in a buyback plan that it would buy back up to 100 million BNB in Q1 2018. The coins are then burned. This means that they are devaluated to increase the value of the remaining coins. This benefits investors. In the future, the cryptocurrency will remain an asset on the trading platform and will be used as gas. Other tokens that are issued by exchanges include Bibox Token, OKB, Huobi Token, and more.
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.
