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.
Verge coin started its cryptocurrency journey in 2014, going by the name of DogecoinDark. The reason it was created was to create a truly private cryptocurrency. The founder of Verge felt that Bitcoin wasn’t anonymous, so he decided to build a new blockchain where transactions could not be traced. Verge uses multiple anonymity-centric networks such as TOR and I2P. The IP addresses of the users are fully obfuscated. The Core QT wallet has built-in TOR integration as well as SSL encryption which adds an extra level of security. Verge is an open source project with an active team of developers from all over the world. The development team is always in close contact with the community. Verge is not a private company funded through an ICO or premining. Wraith Protocol is a technology upgrade package that enables our users to be able to send and receive payments privately across our blockchain by enabling stealth addressing services. Additionally this update removes our QT wallet users off of clearnet and migrates everyone to SSL enabled Tor. Verge focuses on security and maintaining user anonymity just like Monero; so that is its latent upside. Many investors are also applauding its unique technology. Having been improved and integrated with the Wraith Protocol technology, verge users are now able to effortlessly switch between private and public ledgers on the Verge blockchain. Before this, private and public ledgers were mutually selected, meaning that they could not co-exist on a very similar blockchain. But investors are today free to use whatever ledger they want. A good example was when Wraith Protocol switched ON – one will not be able to view the transaction data, not even via the blockchain explorer. Additionally, Verge makes obscure the IP addresses in both instances. When coupled with Wraith Protocol Verge certainly becomes the only undetectable cryptocurrency. Furthermore, transaction speed on Verge is light speed at 5 seconds only, using Simple Payment Verification technology. Verge also maintains a community feel since it’s not a private company. Community members are responsible for the direction of its technology and where the coin heads next. It currently offers a number of secure mobile wallets, including the Tor Android Wallet, which offers mobile anonymity, another big plus over Bitcoin. Verges offers five different Proof-of-Work algorithms for mining. They include; Lyra2rev2, Scrypt, X17, blake2s and myr-groestl. Offering a choice of five different algorithms promotes inclusion, since a wider variety of users will now have an opportunity to not only mine but influence the network. Should one algorithm demand greater mining resources, users get an option of just switching to a different one.
