TOKENIZATION

Tokens and Assets (NFTs) can easily be created via the Nexus wallet or Nexus API. NFTs can also be tokenized, allowing for shared ownership and the automatic distribution of royalties or dividends. The fee for token creation depends on the total supply. View our fee schedule here.

To create a token on Ethereum, or many other platforms, developers must write a smart contract (code written in a specific programming language) to define the utility of the token and its distribution. This requires specialized programming skills, and the task can often be quite complex.

NO-CODE (BUBBLE)

Non-coders can build low cost DApps with the Nexus Bubble plugin that connects to the Nexus API. Bubble is similar to WIX, though is geared towards building API driven web-apps rather than static pages. If you are familiar with JSON-APIs, you can work directly with the Bubble API connector.

We provide access to a private-mode testnet, if you would like to test or develop the functionality of Nexus without paying fees. Note, our testnet is not permanently maintained, and you are advised to move your DApp to a private network or the public chain when possible.

INTEGRATED API

Nexus DApps are powered by a JSON-API (Application Programming Interface), allowing you to integrate blockchain functionality with only web development skills. Nexus provides a wide range of well tested commands that reduce the time, risk and costs involved in DApp development. APIs include, but are not limited to: ‘User’, for the integration of Signature Chains for account creation, ‘Finance’, for NXS related actions or token creation, and ‘Asset’ for asset creation (NFTs). The API also supports a SQL like query language, with advanced search and filtering of registers.

CONTRACTS

The contract domain-specific language (DSL) is designed for users who are familiar with the command interface. It enables conditional contracts to be written directly into the API with the use of english words. This approach also allows people to be able to read or interpret contracts.

Users pay the known cost of contract execution, which depends on the number of operations involved in the contract. The fee is calculated before the transaction is broadcast. This is a very different approach to Ethereum, where users are required to set a Gas limit, resulting in higher fees in times of increased network demand. This sometimes causes Ethereum contracts to fail, while the user still has to pay the contract costs. View our fee schedule here.

HYBRID NETWORKS

Hybrid Networks are designed for individuals, businesses and organizations who have a need for a dedicated network for their DApp or ecosystem. A hybrid network has all the features of public chain, while granting access for free transactions, contract execution, and token and asset (NFT) creation, at the cost of dedicated hardware and hybrid network fees.

With the release of Tritium++, Hybrid Mode will be made available as an out of the box solution. It will supply security services, such as permission access, while granting autonomy, and privacy. The owners of the network can also design their own fee schedule for transactions, as well as tokenomics.

MODULES

Wallet modules (also known as extensions or add-ons) allow users to customize and add functionality to the Nexus desktop wallet. Our wallet is a web-based application powered by Electron, therefore developers can build modules using web languages, i.e. HTML, CSS, and Javascript.

CREATIVE & ENTERTAINMENT

Digital Rights Management: All types of digital creations can be registered as unique assets (NFTs) on Nexus. They can then be tokenized allowing for shared ownership, and the automatic distribution of royalties to token holders. Artists across the creative scenes are learning how they can monetize their creations while cutting out the middleman. Digital assets include: Music, Audio Books, Art, Photography, E-books, Film.

Virtual & Physical Collectibles: Assets (NFTs) can be used to build entire metaverses that can integrate into games, art galleries, and events etc. Virtual assets include: In-Game Items, Skins, Weapons, Digital Art etc. Alternatively, assets can be linked to physical objects such as Clothes, Jewelry, Antiques or Physical Art to prove authenticity and scarcibility.

Tickets: Assets (NFTs) can be used to issue tickets in order to reduce fraud, and with the release of Protected Assets, tickets can be made to be revocable to prevent resale on secondary markets.

ASSETS & GOVERNANCE

Environmental & Energy: Nexus assets (NFTs) provide the technology to trade and track environmental and energy assets. With the release of the P2P Market API, developers will be able to build exchange platforms for their assets, eliminating the need for intermediaries, such as brokers. Assets include, but are not limited to Carbon and Solar credits.

Securities & DAO: Tokenized assets can be used for securities and DAO tokens, where the asset represents the registration of the organization and the tokens represent shared ownership. Payment of dividends or surplus revenue can then be automatically distributed to token holders.

Voting & Governance: Tokens or assets (NFTs) can be used to record cryptographic and transparent votes, and with the release of the DAO API, DApps can add features for the decentralized management of funds and resources.

TITLES & RECORDS

Public Titles: Assets (NFTs) can be used as a record for legal titles that represent private property. Being transparent, anyone can easily verify the authenticity of a public title on Nexus, without having to access a central database. Contracts can also be used for the decentralized exchange of public titles, eliminating counterparty risk. Public titles include, but are not limited to: Automotive, Real Estate, Internet Domains and Trademarks.

Non-transferable Titles: With the release of Protected Assets, NFTs will have the additional functionality of being non-transferable and revocable by the issuer, therefore are suited to certified systems such as Identity Cards, Memberships, Educational and Professional Certificates, Licenses, and KYC (know your own customer).

CopyRights & Unforgeable Records: Any important digital document can be hashed and authenticated as an asset generating a timestamped immutable fingerprint. Documents include, but are not limited to: Legal Agreements, Waivers, Insurance Records, References (landlord and employment), Copyrighted Material, Patents, Medical Records etc.

Supply Chains: Assets (NFTs) can be used to provide transparency into the supply chains of different products such as Agricultural Produce, Commodities, Manufactures, and Electrical Components etc. Product certificates include: Organic, Fair Trade, Sustainable, and Quality Assurance, etc. The Asset API can also be used to develop DApps to streamline production processes and prove chain of custody.

DECENTRALIZED INTERNET

NEXUS PROTOCOL

Web 3.0 or Decentralized Web (DWeb), is the promise of emancipating digital communication by reducing our reliance on centralized network infrastructure. The Nexus Protocol takes this a step further by creating decentralized reputation driven routing services, at the level of both hardware and software, providing an alternative to Internet Service Providers (ISPs). The Nexus Protocol is driven by a security focused operating system (LX-OS), utilizing the immutability of Nexus to verify it’s internal states, making it resistant to most known operating system level exploits.

The internet is a remarkable feat of engineering, however it fails to maintain both security and openness at the same time. As a step forward, Nexus has designed the ONE stack (Open Nexus Execution) that will support online services, verifying sources of information, through authenticated reputation, where the freedom of information is unhindered.

TOKENIZED SATELLITES

Traditionally, deploying an entire satellite constellation requires a significant amount of capital. Today, it is possible to create incentive-based systems using tokenization to crowdfund micro-satellites. Each constellation will be represented by a supply of tokens created on Nexus that manage ownership, and optional income and voting rights. Micro-satellites will be launched into Low Earth Orbit (LEO), will run Nexus’ operating system (LX-OS), and utilize reputation-based network services to protect against malicious entities attempting to monopolize the network.

GROUND STATIONS

Satellites will connect to phased array antennas, which are electrically steered and are capable of realizing high gains and mobility. These antennas can be installed on roof tops and on the top of vehicles. The antennas will connect to transceivers on the 5.8 GHz ISM (Industrial, Scientific, Medical) band, commonly used in Wi-Fi routers. The expansion of network hardware will be incentivized with revenue from engaging in geo-spatial contracts, for content delivery, edge computing, and routing services.

BLOCKCHAIN

VIRTUAL MACHINE

Nexus is built to verify the authenticity, as well as the computation of data. It is powered by a seven-layered software stack operating as a 64-bit register-based process virtual machine (an interpreter) rather than a stack-based script, EVM, or JVM. Each layer carries out a specialized process increasing the efficiency of contract processing.

SIGNATURE CHAINS

A Signature Chain generates one-time-use private keys that are derived from your Nexus wallet credentials (Username, Password and PIN). A Signature Chain is a personal identity on Nexus, which records all of your transactions and ownership history of digital assets. You no longer have to manage key and wallet backups, or use a plug-in such as Metamask.

QUANTUM RESISTANCE

Signature Chains enhance the security of existing DSA (Digital Signature Algorithm) by publishing only the public key’s hash until the key is used, while deterministically generating a new key once the old key is used. This results in high levels of security, as the attack window to brute force a private key is reduced to 500 ms. Signature Chains utilize the following cryptographic functions: FALCON (a second round contender for the NIST Post-Quantum cryptography competition), Argon2 (winner of the password hashing competition, and a superior alternative to S-Crypt or B-Crypt), and Keccak (winner of the SHA3 competition).

THREE-DIMENSIONAL CHAIN (3DC)

The Three-Dimensional Chain (3DC) is designed to solve the 'Blockchain Trilemma', an opinion that only two of three qualities; Security, Decentralization, and Scalability, are achievable concurrently. The 3DC has three consensus layers that check and balance one another creating security and decentralization, while the foundation layer aggregates sharded state, to achieve scalability.

OPERATING SYSTEM

LX-OS, the Nexus Operating System (OS) will initially run on micro-satellites and IoT (Internet of Things) devices, which generally have weak security models. LX-OS uses Signature Chains to authenticate the runtime memory, file systems, and other system servers. It will operate on a distributed filesystem, solving the problem of moving the entire App & OS state from one device to another. LX-OS is built on the seL4 micro-kernel, which when combined with Nexus, can resist attacks from malware, backdoors, and other common vulnerabilities. seL4 is part of an ecosystem supporting active use in various domains including automotive, aviation, infrastructure, medical and defense.

The Lower-Level Library (LLL) is the backbone of LX-OS. The LLL contains three main components: Cryptography (LLC), Database (LLD), and Protocol (LLP). The LLC is a collection of useful cryptographic functions including Quantum Resistant algorithms, the LLD runs in constant time O(1) handling large datasets without losing performance, while the LLP allows the rapid development and deployment of high performance binary or hyper-text protocols.
