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.
The district0x network is a collective of decentralized and autonomous marketplaces and communities, also known as districts. These districts are built upon a decentralized and distributed open-source framework, the d0xINFRA network, which is powered by Ethereum smart contracts. The district0x network aims at creating a friction-free, virtual economy where the users will be able to make buying and selling decisions, complete transactions, and even rank their peers with just one simple click. District0x aims to develop a flexible, and free market with advanced entrepreneurial concepts. The District0x infrastructure has a very neat concept with some well-outlined features, such as the staking interface. A staking interface is put in place that allows DNT holders to have open control over the districts through an Aragon governance layer for all markets that come online. Post creation of a district, an Aragon entity will also be created that people can use to interact with this staking mechanism. After staking a user will receive voting rights in that district. Using the creation interface, one can remove central power structures from any marketplace without the additional need for development or programming skills. It can be described as the WordPress of dApps where the districts being launched are like wordpress templates and the auxiliary modules are WordPress plugins for extended functionality. While it is very difficult to buy lesser known cryptocurrencies using fiat currencies (dollars, euros) directly from crypto-exchanges, district0x or DNT can be easily purchased from various exchanges using Ethereum or Bitcoin as the base cryptocoin. Binance is one of the popular exchange platforms that can help trade Bitcoin or Ethereum for District0x. One can use various wallets like myetherwallet.com to store the district0x (DNT) coins. Coinbase, Blockchain, Exodus, Trezor Hardware Wallet are also wallets that supports district0x. District0x, differs from most coins in its underlying concept and the architecture it is built on. The concept of interconnected districts and marketplaces promises a novel structure to the modern economies. What a lot of users are missing out on is the fact that it is a staking mechanism and not just a voting token. Staking is basically the process of mining the PoS (proof of stake) coins. Early investors will be able to lock their tokens to a specific district on the network, thus being able to participate in its governance later. DNT tokens can be staked in districts, thus they not only give voting power and privileges within that district but also provide district-specific tokens depending on when the investor had started trading. For example, early investors of the PoS token will be able to make decisions about the distribution of profits among stakeholders, the intricacies of the business model etc. DNT can basically be considered as a dynamic stock in the future district0x ecosystem. By joining the district0x, the user receives district0x coins. They allow the owner to exercise the right to vote for district proposals and make decisions within certain districts. This includes, for example, voting on proposals concerning the future of a particular district or setting fees. The scope of shareholders’ rights is outlined in the bylaws and varies according to the specific scope and purpose of each district. District0x platform users can interact with the functions and services provided by each district. Users can also freely create their own districts. For example, on Ethlance, the first district in the District0x network, users can post job offers or search for new jobs.
