Nexus Earth (Ticker: NXS) is an open-source peer-to-peer network utilizing ground-based mesh networks and a Low Earth Orbit Satellite “Constellation.” Nexus Earth is looking to take on Bitcoin as the king of digital cash while simultaneously looking to deploy their own internet infrastructure.  They claim to be “Quantum-proof” in anticipation of the introduction of quantum computing which has long been considered the doomsday device of current cryptography standards and thereby the death of most current blockchain networks. 
One of Nexus’ foundational thoughts was “decentralizing decentralization” by providing a solution against blockchain mining powerhouse centralizations like what can be seen in Bitmain’s production of the ASIC miners that run most of the BTC network, and mining pool monopolies as currently seen in Ethereum. 
Nexus’ native cryptocurrency is NXS, which is internally-developed and free from any ties to another platform. Transference of NXS coin is the premise on which the entire Nexus ecosystem can provide a truly decentralized and “uncentralizable” currency network, with plans to be accessible from the most remote corners of the Earth.

Nexus was founded by Colin Cantrell, son of original SpaceX founder and CEO of Vector Space Systems, Jim Cantrell. Colin’s vision is to utilize decentralized methodologies to foster a more connected world. Colin originally started the project under the name CoinShield, which at the time was an attempt to protect the emerging crypto-community from pump-and-dump schemes on the marketplace and ensure quality crypto-standards. 
Though not officially on the Nexus team, Colin’s father Jim Cantrell has an extensive list of success in the aerospace field, and has held vast executive titles and board seats within his career beginning in 1987 with Jet Propulsion Laboratory. In 2016 Jim founded and remains CEO of Vector Space Systems, a company focused on the launch of micro-satellites, and with whom Nexus has an existing partnership. 
Alongside Colin’s connection to Vector, Dino Farinacci, founder of lispers.net, was onboarded to the team sometime between his and Colin’s initial contact at the Nexus Conference on September 21st 2017, and early 2018. Dino worked on original Internet Protocols with Cisco Systems and was one of the Nexus’ first advisors. Dino is a member of the IETF, and is said to have developed more network protocols than anyone on Earth. 
Utility and Incentives
Nexus is designed to be highly scalable and a decentralized cryptocurrency payment system for global use. With their upcoming Tritium update, Nexus plans to incorporate a “smart contract” system with NXS. This development naturally implies that the utility of NXS will be to interact with the network on top of its use in a payment system. 
Nexus runs on a 3-part hybrid consensus mechanism forming what they have deemed a three-dimensional blockchain (3DC).
The 3DC is made up of the Prime Channel, the Hashing Channel, and the Holdings channel. The Prime Channel is a PoW channel in which miners search for 308-digit prime clusters, the data from these computations are provided to quantum physicists as prime number clusters are a heavily researched subject. The Hashing Channel is another PoW channel, though significantly more intensive; Nexus uses an SHA-3/Skein hybrid cryptographic algorithm with hashes 4x larger than Bitcoin’s. Finally, the Holding Channel utilizes a PoS + Trust consensus algorithm accessible to anyone with NXS and a network wallet, creating incentive and utility for participating in the network. As a further means to prevent centralization, the Nexus network is slated to be composed of a 3-part telecommunications network made of a community node mesh network, Low Earth Orbit satellites produced by Vector Space Systems to host the network and its dapps, and provide internet connection. After their 10 year distribution period and 3DC network is completed there will be no transaction fees on the network, but the current standard fee is 0.01NXS. 
Nexus is a highly sophisticated and ambitious project looking to replace both the current internet and existing payment channels on and off the blockchain.
Nexus did not conduct an ICO, but instead minted 55,000,000 NXS to facilitate development from the community effort it arose from. To generate development capital and regulate developer access to these minted coins, they have in place a “Developers Fund” that claims 1.5% - 2.5% commission from mining rewards. Alongside this commission, 20% of block rewards are allocated towards future marketing and the launch of the satellite network. There are currently 78,000,000 NXS with a 10 year distribution period, after which there will not be a cap on NXS distribution and will instead inflate at a rate of 3% through the Holding channel and 1% through the Prime and Hashing channels.
Though designed to be decentralized to the core, there is a vast concentration of coin holdings on the Nexus network with 114 addresses (0.123%) controlling 48.58% of all coins, 8 addresses (0.009%) controlling 18.43%, and 470 (0.5%) addresses controlling 22.29%, which equates to 0.64% of total NXS wallets controlling 89.29% of all supply. A vast number of inactive or test wallets could contribute to this skew. 2.65% of all coins have not transacted in over one year, and 22,631,415 NXS are currently staked amongst 640 users. 95.19% of NXS wallets created have a zero-holdings balance. NXS is listed on Binance and Bittrex.
Nexus is aiming to disrupt legacy payment systems, and existing internet infrastructures. In 2017, global payments generated $1.9 trillion in revenue, while internet access services generated $981.4bn in 2016. 
These targets represent enormous markets, and both are fairly outdated. Financial payment systems are well known for their cross-border and international fees and regulations, giving a global fee-less currency a grand opportunity. Furthermore, internet infrastructures have few competitors, are heavily concentrated in-market, and often regulated and controlled by governing bodies, presenting yet another opportunity for Nexus as a community driven global network.
With the recent announcement of their own cryptocurrency solution, JPM Dollars, JP Morgan & Chase will be a colossal rival in the frictionless payments realm, as well as existing Japanese Bank “MUFG”-backed blockchain payments solution Ripple. Furthermore, with the ongoing development of platform smart contracts and being highly geared as a currency solution, Nexus is taking on two of the biggest names in blockchain head-on: Bitcoin and Ethereum. It is arguable that focusing on one niche is more important especially at such an early stage.
Nexus has a couple notable things going for it that set it apart from many other cryptocurrencies. First, as a coin developed pre- and in absence of an ICO, it has fostered dedicated community development. Second, its consensus mechanism and hardware infrastructures are a novel approach to combating centralizations on multiple fronts.
Current Status and adoption analysis
To date, Nexus has continually progressed on their platform code development and partnership agreements, though overall they are still early in the time-line of their most recent roadmap. The Nexus roadmap shows the three phases of their development schedule: Tritium, Amine, and Obsidian. As can be seen in the picture below, Nexus is still in its “Tritium” phase, which serves as the foundational layer for the next two.
Through continued development, the potential growth of the Nexus Ecosystem is exponential, serving as a revolutionary global P2P network capable of much further reach than what we have today.
The largest hurdles for Nexus, as with most any network, will be community adoption and its ability to gain trust and recognition globally. Nexus is still developing the hardware and necessary partnerships to achieve their full potential, but they’ve made significant progress in positioning the platform in the appropriate areas. As with any great effort, transitions of this magnitude and projects of this scope seldom take place overnight. That being said, should the Nexus platform achieve its goal of decentralized global connection, the potential of an interconnected world its extensive.
