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.
Turtlecoin is a privacy coin that is forked from Bytecoin. Because of this, turtlecoin has Bytecoin’s privacy aspects to it called RingCT. This coin is more of a meme coin, but there are a lot of serious tech advancements as well. For example, they have a 30-second block time. They also plan on having simple smart contracts sometime soon, since they say they already started development. They have 35 developers on the team and they also plan on somehow making the blockchain smaller to sync faster, but this is TBA on the roadmap, and the details of this are not out yet. Turtle coin uses the cryptonight_lite_v7 algorithm so it is ASIC resistant. Born on the 9th day of December 2017, TurtleCoin faced a backlash from a couple of online forums, not because it had such a funny name, but since its initial single command line and included TRTL giveaways. Luckily, TurtleCoin of about three months later is grown a lot and has various versions compatible with Apple, Windows and Linux OS. Turtlecoin could be the ideal project to get involved in while it is still in the initial stages. There is more potential for return on investment with a microcap coin than there are with established altcoins. Moreover, you do not have to hand over tokens in an overhyped crowd sale to be a part of this. All you really need to do is download the mining software and get hashing. The coin is one of the easiest to mine as was the developer’s intention. Moreover, given the exciting roadmap that the team has ahead for the project, the future prospects also look quite promising. Private smart contracts and no sync blockchains could push the coin towards mass adoption. Fast With blocks being created every 30 seconds on the Turtlecoin blockchain and transactions taking just seconds, sending and paying with TRTL is a breeze. Easy Having an extremely active development team and a lively, helpful community, you can start using TRTL in minutes, no matter your familiarity and/or expertise with cryptocurrencies in general. Mining TRTL is also very easy to get into with simple, detailed how-to guides. Safe With its beginnings as a fork of Bytecoin, Turtlecoin offers the same degree of privacy and anonimity with its use of ring-signatures. Just like using paper cash, paying with TRTL allows you to spend your money the way you want. Being completely open source, the TurtleCoin project is growing daily. We actively encourage the community to jump in with fresh ideas, no matter your skillset or level of experience. Just hop into the discord and say hello!
