Nexus is the first truly quantum-resistant blockchain, incorporating advanced cryptography designed to negate the threat posed by quantum technology of the future. The 3DC combines 571-bit private keys, 1024-bit Skein and Keccak quantum-resistant hashing algorithms, and an evolving signature scheme called signature chains. Signature chains update the private and public keys that secure your address and obscures them after each and every transaction, maintaining the integrity and security of your account even on mobile wallets. Signature chains offer several advantages over equivalent quantum-resistant schemes such as BLISS and Lamport signatures, being extremely compact and lightweight, making it ideal for blockchain applications. The Nexus coin (NXS) is the currency of the network. There’s no cap on the amount of NXS that will be minted. Instead, the coin has a 10-year distribution period in which 78 million NXS will be distributed until September 23rd, 2024. After this time, the supply will inflate each year by a maximum of 3% through the holding channel and 1% through the prime and hashing channels. Nodes create blocks, on average, every 50 seconds, and an NXS transaction requires 6 confirmations. Currently, most transactions cost 0.01 NXS. However, once the 3DC is built and 10-year distribution is complete, transaction fees will disappear. Instead, the system will absorb the fees through inflation. Nexus didn’t hold an ICO. Instead, the project has a Developer Fund that takes a small commission from mining rewards. This commission starts at 1.5% and increases to 2.5% over 10 years. Additionally, 20% of the block rewards are slotted for marketing as well as the production and launch of the Nexus satellite network. Colin Cantrell, also known as Videlicet, is the founder and lead developer of Nexus. He first named the project Coinshield (CSD) when starting in September 2014. The original code only contained the prime channel; the team added the hash channel in October 2014. In April 2015, the team rebranded to Nexus, and they added Proof-of-Holdings in July 2015. Besides partnering with Vector on the satellite network, Nexus has also joined forces with SingularityNET to provide their 3DC architecture to the project’s decentralized AI network. Moving forward, Nexus is releasing major updates following their TAO (Tritium, Amine, Obsidian) roadmap strategy. The releases include the 3DC, mobile wallets, quantum resistance, and the satellite network, among many other things. The creation of new NXS is capped at 3 percent per year and is earned through securing the network by mining or staking. The platform is developed and maintained by the Nexus Embassy who is funded through a 1.5% commission on each block produced and from funds acquired through early mining of NXS. The commission will also gradually increase from 1.5 – 2% over the next 10 years.
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.
