Spendcoin SPND to FOAM FOAM Exchange

Crypto Pair Details: SPND to FOAM

Spendcoin SPND

Spendcoin is a decentralized cryptocurrency that powers the Spend.com ecosystem of products. Spend has two financial services products, the Spend App and Spend Card, which are products of Spend.com that give our users a multi-currency digital wallet that they are able to store fiat and digital assets/currencies. They will be able to buy, sell, store, manage, and exchange all supported currencies within the app. The Spend App is available on iOS, Android, or Web based devices. The Spend prepaid debit card allows users to send fiat based currencies loaded onto it via the Spend App anywhere that accepts MasterCard. Spend Foundation is also launching a decentralized educational platform called Blockchain University (bu.org). Blockchain University is designed to run off our open-source blockchain called Cross Ledger which incorporates a hybrid delegated proof-of-stake consensus model called Proof-of-Support. Proof-of-Support creates a learning based ecosystem that rewards those users who support and answer the knowledge base and Quora style system. Spendcoin will be the native digital currency powering the platform. Blockchain University and Cross Ledger are planned to launch in 2019.

FOAM FOAM

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.
