There is an increasing number of smart contract platforms rolling out in the crypto space, with many becoming household names. However, a dark horse in the race to be the most efficient and secure blockchain is ‘Nexus’. Given its low market cap, most people have never heard of this seven year old blockchain, yet it delivers far more than many of the leading smart contract platforms today.
The Nexus roadmap is extensive, with massive upgrades and new features still to come, many of which are just around the corner. However, let’s now focus on the top 10 reasons to build on Nexus based on its current capabilities. All these features can be used by developers on the public network or their own private chain.
1: Platform-agnostic API
Nexus was designed from its inception with composability in mind. The team and the community have been building a "connected world" that is achievable only with a trustless bridge between the mainstream Web2 infrastructure, such as marketplaces, development platforms, automation tools, game engines, and social networks, and the emerging Web3, powered by Nexus’ integrated API (Application Programming Interface) kit. Decentralized applications (DApps) built on Nexus interact with a JSON-API, allowing developers to integrate blockchain functionalities into their traditional applications while having web-development based skills only. Nexus provides a wide range of well tested commands that reduce the time, risk and costs involved in Dapp development. Nexus’ unique architecture enables seamless interoperability between the data-rich Web2 and the tokenized Web3.
2: Fueling the No-Code Movement
Bubble is a leader in the no-code movement, which offers a powerful point-and-click web editor and cloud hosting platform that allows users to build fully customizable web applications and workflows. Nexus’ bubble plugin contains several API calls that interact directly with the Nexus' blockchain. It is a powerful tool for anyone eager to build tokenized peer-to-peer NFT (Non fungible token) marketplaces, visual art galleries, music and video streaming platforms, social networks, and many other services, creations, and ideas for the Web3 era.
3: Easy Token & Asset (NFT) Creation
Tokens and Assets (NFTs) can easily be created via the Nexus wallet or Nexus API. The fee for token creation depends on the total supply, whereas the fee for NFT creation costs 1 NXS. Unlike regular tokens, NFTs are unique assets on the blockchain and can be used to represent many different types of digital and physical assets such as Digital Art, Physical Collectibles, and Music. NFTs can also be tokenized, allowing for shared ownership and the automatic distribution of royalties or dividends. View our fee schedule here.
Nexus has a multi-tiered naming system that offers globally unique identification, personalization and branding opportunities. Three categories exist: local names, namespaces, and global names, all of which can be created via the Nexus desktop wallet. A user only has to type in the username and account name to send funds to another user (eg. send to jules:default). Names can be created within a namespace for the purpose of naming accounts within an organization. A namespace owner can create and sell names just like domain registrars sell domains. Global names represent a unique, stand-alone name that can be used for token tickers and other uses. Global name ownership can be transferred just like namespaces, creating the opportunity for secondary markets.
5: Mobile-friendly Automated Key Management
Nexus has built a groundbreaking transactional architecture called ‘Signature Chains’ that replaces the legacy UTxO, and so-called account based models, to simplify application development, wallet usability, and therefore boost user adoption. A Signature Chain is a personal vault containing the historical record of every single transaction and digital asset ownership of a single user on the blockchain, and is accessed with user-generated credentials (username, password, and PIN) by a decentralized login system. Signature Chains make Nexus the perfect mobile-friendly Web3 development stack by eliminating manual dependency on key management plugins such as MetaMask, enabling developers to build tokenized Dapps with simplified UI/UX that are as easy to use as Facebook, Snapchat, and TikTok.
6: Quantum-Proof Security
Signature Chains also enhance the security of existing ECDSA (Elliptic Curve Digital Signature Algorithm). They generate one-time-use key-pairs derived from the Nexus wallet credentials, of which the public key’s hash is only published once the key-pair is used, while deterministically generating a new key-pair while signing the next transaction. This results in a higher level of security compared to other platforms as the attack window to brute force a private key is reduced to under 200 milliseconds. In addition, 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) to improve its robustness.
7: Feeless Transactions
It is free to send and receive NXS, tokens and assets (NFTs). However, there is a 0.01 NXS fee applied to every simple contract generated within 10 seconds of the last transaction to prevent transaction spam attacks on the network. Each transaction on Nexus executes a contract and each transactional-contract can contain a maximum of 100 additional contracts. View our fee schedule here.
8: High Throughput
Our latest test shows that the current release can achieve 655 transactions per second on a live application, with each transaction able to contain up to 100 contracts.
9: Custom Database
Nexus has developed its own database called the Lower Level Database (LLD). It is a fast and modular storage engine that is capable of outperforming most of the current embedded database engines that exist. Tests have shown an average of 0.33 seconds per 100,000 writes and reads to disk, making it faster than Google’s LevelDB. LLD multithreading demoing from May 2021 showed 1024 threads at 578M reads per second, and 3333 threads reaching 4.2B reads per second. It is anticipated that staying above 1M reads per second will be the standard during live application.

Nexus.io (NXS) is building a new internet driven by a blockchain-based operating system (LX-OS) and routing protocol (Nexus Protocol), creating distributed satellite constellations and ground based content delivery and edge computing. Underpinning the foundation is the Nexus TAO Framework, a seven layer software stack that enables the simplified implementation of smart contracts, Decentralized Applications (DApps), tokens, and Non-Fungible Tokens (NFT’s, i.e. Assets) through a set of extensible Application Programming Interfaces (APIs).
Contracts: Nexus supplies a 64 bit register-based virtual machine as the heart of its smart contract engine. A suite of APIs gives developers access to numerous ready-made contract functionalities. This relieves DApp developers from the burden of learning a smart contract language.
Tokens & Assets (NFT’s): Basic token creation is simple for even non-technical individuals with the Nexus desktop wallet. Arbitrary data can be stored on the Nexus blockchain in the form of assets. Once established, assets can be transferred to other accounts optionally with specified contract conditions (i.e. exchanging NXS / tokens).
Ease of Use: Nexus’ SigChains addresses a primary blockchain limitation — private key management. Users can login to their Nexus wallet with a username, password, & PIN, providing access to all accounts, tokens, and assets. This eliminates the need to backup wallet.dat files and manage private keys.
Database: Unlike most other blockchains that rely on Google’s LevelDB or Oracle’s BerkeleyDB for blockchain storage, Nexus has developed the Lower Level Database (LLD) that outperforms most storage engines by orders of magnitude and remains constant time, meaning it doesn’t slow down as you add more data to it.
Security: The Nexus security model uses many layers of redundancy to provide security to the system. The primary methods include using uniquely generated private keys for every transaction (attack window reduction), and the secondary use of Quantum Resistant (QR) cryptography such as FALCON and SABER.
