Nexus Advanced Contracts

Nexus Advanced Contracts

Enterprise adoption is instrumental to blockchain technology becoming mainstream, and Nexus Advanced Contracts are the next step in leading this progression. Existing Smart Contracts have experienced issues in relation to ease of use and scalability due to a Turing complete system. Addressing these issues, Nexus has produced what is in essence a ‘Register-based Virtual Machine’, set for release in January 2019 with the Tritium upgrade. Tritium will allow developers to access the technology of Advanced Contracts simply through an API set. Before an explanation of Advanced Contracts is given, some context will be provided as to how conventional Smart Contracts function.



Smart Contracts

Smart Contracts are self-executing. Their design is to enforce the terms and conditions of a contract through programmable logic, reducing the need for third party intermediaries such as brokers and banks. Smart Contracts are an additional layer of processing above the ledger layer, i.e what is known as ‘the blockchain’, and are comparable to small computer programs that hold a state of information. The calculations of the contract are carried out by the processing nodes of a blockchain, which change the state of the information. Given that the calculations or processing is carried out by distributed consensus, the state of a Smart Contract is immutable.

Bitcoin was the first cryptocurrency with built-in Smart Contract capabilities, which it calls ‘scripts’. Scripts are not Turing complete and contain byte code. Ethereum augmented these capabilities into its ‘Turing Complete Smart Contracts’, which are generic to developers’ needs. Ethereum gives developers more access to contract functionality on a blockchain through a custom programming language called Solidity, which is then compiled into assembly language that is run on the Ethereum Virtual Machine (EVM). The EVM is a ‘Stack-based Virtual Machine’ that processes each instruction in turn.

Though very capable, Ethereum has experienced some issues in regards to security, performance, and ease-of-use, predominantly because of its Turing complete design. Some notable cases include the $75m DAO hack on Ethereum, and the $286m Parity bug. Vulnerabilities existed due to the large complexity of a Turing complete system, and the resulting difficulty of resolving bugs in a protocol written in immutable code. The complexity of operations that support universal computation or Turing complete designs also limit scalability. A universal system has a higher degree of complexity, and can not therefore compete with technology that is designed for more specialized tasks. An example of this observation would be the comparison between a CPU (Central Processing Unit) with a ASIC (Application Specific Integrated Circuit) in the mining of cryptocurrency. A CPU can’t compete against a SHA256 miner, as its complexity and design is geared to support universal general computation, not specialized computation. A similar conclusion could be drawn when a comparison is made between the system design of Ethereum (universal), and Nexus (specialized).


Nexus Advanced Contracts

Nexus has developed a ‘Register-based Virtual Machine’, a specialized contracting engine with greater capabilities than the EVM. Unlike the the EVM, which is defined by only two distinct layers of processing and is dependent on a Turing complete system, the Nexus contract engine is facilitated through the seven individual layers of the Nexus Software Stack, each designated to carry out specialized processes.

The third layer of processing is called the Register Layer. Here, the states of individual pieces of information contained by Advanced Contracts are recorded in architectural components called registers. Registers are used by typical computer processors and provide easy access to memory storage of frequently used information or values. With respect to Nexus Advanced Contracts, each register is owned by a Signature Chain. Therefore, the ownership and write access of a register is validated by the second layer, the Ledger Layer. The fourth layer is the Operation Layer which defines the rules of the state changes to a register, called ‘operations’. The operations are carried out by validating nodes that change the state of the registers by distributed consensus. The design provides the required functionality of a contract engine, without the over complexity and complications of a Turing complete system.

The ownership of a register can be transferred providing many proof of ownership use cases. Examples of such include titles, deeds, digital certificates and records, agreements, or any other digital means of representing tangible assets or time-stamped events. A register can also be owned and governed by another register, creating a relationship between many users. Relations can be used as proofs on the Operation Layer to provide additional functionality. An example of this would be a register that holds metadata representing the ownership of an item, and it being owned by another ‘token register’. The token ownership signifies partial ownership of the item, which provides the possibility for further use cases such as royalty payments with split ownership.

Conditions or stipulations can also be coded into Advanced Contracts by validation scripts or Boolean logic. Validation scripts require a transaction to fulfill a certain set of conditions to execute, which allows a user to program in stipulations on the exchange of NXS, tokens or any other digital asset. This allows a user to void transaction orders, place time locks on funds, or exchange any digital asset without a central intermediary.

Advanced Contracts which will be accessible through an API set will be able to improve many existing processes, including digital ownership, tokenization of assets and enterprises, digital rights, royalty payments, supply chain management, escrow services, financial applications, legal documentation of digital signatures, and many more.



The standards of object registers, operation codes, and API methods will be defined through working group consensus, to ensure a consistent connection between developers and users. Nexus borrows a similar model to the Internet Engineering Task Force (IETF) that provides the working groups for all RFC (Request for Comments) standards. This is important to drive a vibrant ecosystem forward. Just as we have seen with the success of the internet, we hope to continue this success in the next era of global connection: blockchain, artificial intelligence, and satellite communication.

Nexus Newsletter December

Nexus Newsletter December


In the lead up to Christmas, and the much anticipated Nexus Tritium core release in January 2019, the Nexus development team is hard at work preparing for December’s public test nets and creating the module store. In late November, Colin Cantrell presented at the Cryptofinance conference in Oslo, and Nexus held its first European Developer Workshop in Warsaw.


Tritium Update

The LISP mapping system is running on Tritium and is being tested. Crypto-EIDs which are IPv6 are also ready, and the team is moving forward with linking them to signature chains. Advanced Contracts are also in testing with new validation scripts which are being finished. The Logical and Interface layers are entering into their final phases of beta. A public Tritium testnet is aimed for the end of December, while the API and RPC are awaiting final core features to be completed.


Developer-Friendly APIs 

The Nexus Tritium update will allow developers to integrate with the Nexus blockchain through an easy to use, feature-rich API set. APIs will create user-friendliness for developers who will be able to build in a wide range of languages, and interoperability for existing private systems to interact with the Nexus blockchain. Nexus has designed its software stack based on the Open System Interconnection (OSI) network reference model, with the fifth layer as the API layer.

LISP Update

Dino has added a new draft update to ‘LISP-Decent’ to describe a pull-based decentralized mechanism for the LISP mapping system, which can be read here. He has also been holding bi-weekly Zoom meetups of which the links to the recordings are below:

Zoom meetup 1 shows how packets flow, how Nexus peer connections are made, and how the containers are connected to the underlay.

Zoom meetup 2 shows how packets are encrypted and sent on the IPv6 overlay due to the Locator / ID Separation Protocol on the IP address network layer.

Zoom meetup 3 shows how crypto EIDs, the mapping system, transactions over the IPv6 overlay, and Nexus nodes will protect users against IP address spoofing.


CryptoFinance, Oslo

Colin, Alex and Jules travelled to Oslo for the BitSpace CryptoFinance conference. At the conference Colin spoke on two occasions, as a keynote on how Nexus is designing a decentralized internet infrastructure through the use of cube satellites, and on a diverse and lively panel with Richard Hart. We would like to thank the Bitspace team for organizing such a great event, and we look forward to attending the next one. Recordings of Colin’s presentation and the panel discussion are available on the following links:

Nexus Developer Workshop, Warsaw

Nexus hosted its first European Developer Workshop in Warsaw, Poland. Colin Cantrell presented the design of the proposed social organizational architecture. Alex El-Nemer presented on some of the Tritium use cases, with insights into the technology Nexus is building with partner SoundVault who specialize in music licensing. We would like to thank all the Polish community for their continued support and great hospitality. The workshop recording can be viewed here.


Sustainable Supply Chains

It is clear that organizations can only operate effectively with easy access to products and services. Likewise, no organization can continue to grow if late payments and poor procurement processes remain in place. This is where blockchain technology can play a crucial role, in both the modernisation and improvement of the logistics and operations which are vital to the performance of supply chain systems.

Nexus Earth Newsletter November 2018

Nexus Earth Newsletter November 2018

It has been a very productive month for Nexus with the commitment of many new lines of code for the Tritium upgrade, ambassadors attending conferences, engineers meeting at the Internet Engineering Task Force, and the continued development of our distributed Embassy structure. The developers are also continuing to improve the Tritium Wallet and gearing up for the next set of beta testing.


Tritium Development Update


Most of the foundational developments of Tritium are complete. Recent tests of the Lower Level Library (LLL) show requests reaching 197,744 per second, and the Lower Level Database (LLD) handling the workloads handed to it when testing Lower Level Crypto (LLC) verification at over 4k tx/s.

The Nexus developers are at the stage of weaving together code over the network, establishing local databases to handle Signature Chains and register indexes, and adding lower level RPC commands to interact with the Ledger, with the higher level API being the interface in the command set.

Jack McGowen, a new Nexus developer, has been actively working with Scott Simon on the backend LLL-TAO Framework, cleaning up the code and helping to weave it together with the Tritium and Legacy code, into a live Tritium node (minus Tritium activated features) running over the live network. The code cleanup process has involved writing new code for existing functionality, and code comment-based documentation. A lot of the legacy code contained functionality from third party libraries such as boost. “We wrote new code to replace boost while maintaining the same functionality so now the code is less bloated and more portable. I got so excited about removing boost, that I removed it from the prime GPU miner as well,” said Jack. Moving forward, new users looking to build the code from source will no longer have to download boost. The team will use doxygen, an industry standard tool, to build an HTML format document from code comments that will be the foundation for learning for developers building on top of Nexus.

According to Colin Cantrell, in his latest TAO update, “Tritium will be released by the end of January, 2019. Yes ,  a timeline! As we have noticed over the last year, the removal of road maps and timelines didn’t do what was intended, it only created further uncertainty and rumors about the project. As we move into Chapter 3 of our history with distributed Embassies, new architecture, and distributed governance models, we felt it was appropriate to augment this with commitment from the development teams to set and meet deadlines.”

Read the newest TAO Update here.


Signature Chains


The Nexus Tritium update implements Signature Chains (Sigchains) that create a unique cryptographic identity system, a key-management authorization system, and a proof-of-ownership device. This allows a user to safely transfer and prove ownership of assets and data through advanced contracts. When a user publishes, transfers, or leases data, an event is recorded. This allows for a relationship between users and transparent chains of events to be recorded. That relationship provides the utility of managing data and assets: titles, deeds, patents, currency, records, music, copyrights, trademarks, websites, etc.

Hash Wars


The Bitcoin Cash community went through yet another civil war where miners had to decide which new protocol upgrade to support with their hashing power. The two sides: Bitcoin Cash ABC (ABC) and Bitcoin Cash Satoshi’s Vision (SV), split on November 15th, 2018. Craig Steven Wright, leader of SV,  threatened the entire cryptocurrency ecosystem, promising he would use every miner that supports his chain to 51% attack ABC, followed by attacks on all other blockchains. Alas, the first hash war was anti-climatic as the majority of hash power turned out to be on the side of ABC. Of course, the situation may still change if there is shadow mining afoot.

During the conflict, Colin Cantrell shared his perspective on the hash wars, and reminded us that “we must take a moment to ask ourselves: “What is our vision?” And if our actions aren’t in accordance with this, we must find ways to support projects that are.”

World Crypto Conference


World Crypto Con was hosted in Las Vegas over Halloween week, and Nexus was a big part of the 10 year Bitcoin White Paper celebration. Nexus’ participation was funded by the community, and the event was staffed by Dionna and Anastasiya (US Embassy), Chris (Community Volunteer AU), and Cain (AU Embassy). Nexus sponsored the conference’s hackathon and the Bloqathon, which was hosted and organized by the Bloq team. Anastasiya gave an informative speech to the participating developers explaining the Tritium upgrade. Nexus also had a kiosk in a prime location, stacked with a 50 inch TV playing the wallet demo, and lots of Nexus swag. The team educated attendees about the Nexus technology along with our ledger layer scalability architecture. We want to thank everyone who stopped by to talk about the tech! A special thank you to community members Chris and Frank for going above and beyond to support the Nexus vision!

Blockchain Unbound: Tokyo


Nexus Ambassador, Dionna Bailey, attended the Blockchain Industries conference Blockchain Unbound: Tokyo. She was interviewed by several podcasts, participated in the Satoshi is Female & Women in Blockchain Luncheon, and connected with blockchain projects in Asia. Additionally, she represented Nexus in the Token Alliance Roundtable Tokyo where blockchain leaders in the Asian market discussed the current landscape of the industry and the challenges of regulatory changes. Among the attendees were the former commissioner of the SEC, NEO, Quoine, Huobi, Bittrex, Blockchain Industries, Perianne Boring, and Matt Roszak. As part of our membership in the Digital Chamber of Commerce, Nexus was featured on the front cover of Understanding Digital Tokens book given to legislators in the US and abroad.



Exploring Korea


As part of Nexus’ education initiative, the team has taken steps to expand into Korea. As a result, we now have our homepage live in Korean. There is also a dedicated Telegram channel for those in the community who want to get involved and keep up with news as well as a Twitter channel for public announcements. Future plans include meetups in Seoul as well as other initiatives to grow our international network.

New Nexus Hires


Jack McGowen (@BlackJack)

Jack McGowen has joined the Nexus Core Dev Team! Jack is relocating this month to the US office in Tempe, AZ to work closer with the team as a software engineer. He obtained his BSCS:RTIS (Real-Time Interactive Simulation) from DigiPen Institute of Technology April 2017 and joined the Nexus community shortly after, and has been an active community member for over a year.

Jack learned about the outdated prime miner software and began working on a new one. He found that his GPU programming skills translated nicely from computer graphics to high-performance computing or HPC. “Any miner is trying to solve a HPC problem, and so the problem felt like a natural fit for my skill set.” Jack successfully implemented a fast 1024-bit primality test using Montgomery modular multiplication, and offered a significant speedup from efficient use of GPU resources. “The Prime GPU Miner is rid of boost, OpenSSL, and libprimesieve; it only requires CUDA and GMP to build now.” He has plans to write an even more scalable miner as he continues R&D on an efficient prime mining algorithm, and is currently working on the backend LLL-TAO Framework.

Nexus Earth Newsletter September 2018

Nexus Earth Newsletter September 2018

August was another busy month at Nexus as the team executed its final preparations for the 2018 Nexus Conference and focused heavily on building out the code. The conference agenda is available (check it out here), with a rich lineup including a blockchain 101 seminar, inspirational speakers and panels, and the first ever Nexus working groups.

We want to invite everyone from the community to join us in Scottsdale on Friday, September 21st for these collaborative sessions to help in designing and building the Tritium Software Stack as well as  a new model for a Decentralized Autonomous Community (DAC). We very much look forward to this annual opportunity to gather face to face with the community members who have been so integral in building Nexus. The conference always brings forth exciting opportunities and individuals that shape the code and the project. Don’t miss this final week to get tickets for the conference and make sure to tell your friends!

The Nexus wallet beta is off to a successful start. The team has solicited great insights and has released a sneak peak of the wallet overview page.  Follow the wallet testing in our Nexus Slack or through our many social media channels. Dino Farinacci, founder of and advisory committee member, has been helping with the development of Tritium. He will be presenting at the conference and will share an exciting update with us this month.

Tritium Development Update:

Colin Cantrell, founder and chief architect, revealed a number of interesting updates on the team’s development of Tritium, including a stress test of the LLP/LLD capacity to scale up to 144,485 requests per second, which is well within the requirements for VISA scale ability (20k/second peak).


Dino Farinacci Update:

I am currently working on packaging the tritium software. So the wallet, nexus daemon, and LISP can all come up in a docker container. By using docker containers, the code always runs on debian linux regardless if your hardware platform is running Windows, MacOS,  Android, or Linux. The packaging allows for IPv4 and IPv6 EIDs to be provisioned dynamically so nexus peers can be discovered by seed nodes without any human intervention.

I am also testing each git commit that Colin is creating to test new functionality he has written over LISP. I am making the docker container environment easy for users to manage nexus and LISP by providing handy command line aliases. Additionally, I’m starting to write an application that tests all paths on the underlay to RLOCs.

Nexus Earth Newsletter August 2018

It’s been a busy month as we’ve been preparing for launches both near and far.  As we reflect on our vision and evolution it’s important to revisit our values. We have a renewed focus on getting back to our roots: decentralization, connection, and code.   In order to embrace these roots, we are focusing in and reformatting the 2018 Nexus Conference with an emphasis on education, networking, code, and connection. This revised conference strategy will ensure that the conference is highly productive in advancing our code and subsequent use cases.

Our collective travels over the month have engaged our community in London, identified new potential partners in Europe, solicited insights from the IETF, and furthered our existing partnership with SingularityNET.  The core of Nexus is connecting with humanity and we look forward to sharing some of these connections and partnerships in the near future. Please join us at our 2018 Nexus Conference!

Nexus Wallet Development Update

The new Nexus Wallet is officially in alpha! Join us for the journey as we get closer to the big reveal:

Satellite Update from “Satellite Guy” Phil Swazey

The NXS1 cube satellite (cubesat) is progressing well towards its March 2019 goal date. Vector’s estimated launch date has changed from October 2018 to March 2019.  All of the satellite components have been procured and assembled as a flight engineering model, pictured below. The engineering model of the satellite is now undergoing integration, verification, and validation testing to verify that the components are all operating up to specifications. Once the integration testing is complete the flight model of the satellite will be assembled and placed in a vacuum chamber for further testing to simulate the space environment. Upon completion of testing the satellite will be packaged and transported to the United States from the manufacturer’s (Space Inventor) facility in Denmark .

Nexus has completed the process of identifying all of the components for the building of a ground station to communicate with the satellite once it is in its operational orbit. Approval for the funding of the ground station is currently underway. The ground station will become a key component for the operations and maintenance of the NXS1 as well as the NXS2 satellites.

Nexus: Coming Back to Our Roots

“The spirit of Nexus is freedom, love, and self expression” – Colin Cantrell

Decentralization and connection: the two evolutionary pillars that have sprung up from the blockchain revolution.

They represent the free flow of energy through consciousness: the transfer of information between humans, a transfer of data between machines, the relation of events, and the movements of Nature. Everything in the Universe is interconnected. We strive to find acceptance and to be a part of the flow, to feel at home wherever we go, to get the things that nurture our mind, body, and soul.

This is the direction humanity is moving in and it is clearly seen within the emerging blockchain and cryptocurrency industry. Originally created by a group of pioneers, the technology was built and given to humanity to grow and develop. We believe in the vision of people coming together with their individual skills and talents to collaborate and be a part of something bigger than themselves.

The Nexus community is at the forefront of this movement. Full of passion, curiosity and a keen sense of justice, we are constantly searching for better ways to connect. Yet no journey is without its challenges and lately we have struggled to connect while staying decentralized. Building new systems and structures requires experimentation, drive and collaboration, but it is easy to default to hierarchies and give away our power because that is what humanity has been taught to accept for centuries. That is not the way any longer!

We are free and we are powerful. We all see a variation of a new world where no one is boxed into systems that take away our voice or tell us that our creative spirit is not aligned with some corporate agenda. Self-expression and spontaneous self-organization is at the core of the Nexus philosophy and that is the way forward.

In that spirit, The US Nexus Embassy will be going through a lot of changes in the next few months and focusing on becoming community-centric once again; the root of the blockchain decentralization movement. We are also restarting up our Nexus bounty program. For all those who want to be involved and come up with creative projects, please join our communities on Telegram and Slack. All writers, artists, developers, meme masters, and translators are welcome!

As we collect ideas and suggestions, this incentive program will continue to evolve.

Nexus Conference 2018 Update

In the interest of realigning with our core values, getting back to our code development and community roots, Nexus is evolving the 2018 Nexus Conference to support our overall refocus efforts. We are focusing in on accommodating 300 attendees for a more intimate networking and educational event with increased focus on new code demonstrations including LISP integration and advanced contracting. We will continue to feature many of our amazing speakers sharing insights into the future of technology, with an increased focus on releasing the current state of our code, and progress to create a distributed internet in space. With less overhead and more focus, we can introduce new concepts to help build out those core values: enter Nexus working groups.

An Introduction to Nexus Working groups:

Individuals are invited to come together in Scottsdale to collaborate in the development of the Nexus stack via Nexus working groups. Once the working groups meet in person they will continue their communication and build-out through online interaction. Nexus working groups will be modeled after those of the IETF (Internet Engineering Task Force). Those that participate will have the opportunity to build out the model for how the working groups will operate. The future vision of working groups at Nexus is to have them align and build on a range of topics. If you would like to collaborate in building out the Nexus stack via working groups, or learn more about them, please join us at the 2018 Nexus Conference! Working groups will take place on Friday, September 21st. For more information on Nexus groups you can also join our telegram channel

Colin, Brian, and Dino at IETF Montreal

Colin Cantrell, Brian Smith, and Dino Farinacci ( attended the Internet Engineering Task Force (IETF) in Montreal, Canada, in mid July.  The IETF meets three times per year, bringing together pioneers of the internet to develop protocols.  Dino has been attending IETF for many years, while this was Colin’s second visit and Brian’s first. Hot topics at the meeting included how to scale blockchain, how the IETF could help crypto-currency designers, and how  overlays can help distributed ledgers.

Brian and Dino attended the Sunday night tutorial on ILNP (an alternate way to do locator/ID separation for LISP), and found it useful to compare the pros and cons between ILNP and LISP. Both Colin and Dino presented at the LISP Working Group. Dino presented the ‘draft-farinacci-lisp-telemetry’ draft that Tritium will use to get more underlay measurements of the network when selecting peers. Additionally, he presented an update to ‘draft-farinacci-lisp-ecdsa-auth’ which is being used in IoT environments. Colin gave an update on ‘draft-farinacci-lisp-decent’ (a design for a decentralized mapping system) and shared some new ideas about how a pull-based mapping system could be used by doing algorithmic mapping from an EID (end-point ID) being registered/requested to the map-servers that will be used to shard the database. Additionally, Colin presented high-level ideas on how the DLT can use LISP crypto-EIDs as well as how LISP could use the DLT to validate mappings and store EID allocations. Good feedback was received on the presentations including lots of questions. Updates to all specs presented will follow and action items were put in place to present at the fall IETF in Bangkok.

Colin and Alex visit SingularityNET in Hong Kong

Colin, Alex, and Jules met with Ben Georterzel of SingularityNET to thoroughly explain the scalable technology of LISP and the 3DC. The developers of SingularityNET and Nexus will first collaborate on the research and development of reputation systems, which are imperative to the security of the Nexus Earth network and to the future decentralized marketplace for Artificial Intelligence. Nexus also envisions that different reputation systems could be built to suit the requirements of specific community and commercial applications, to serve resource sharing ventures that require data to be verified by an immutable consensus mechanism. The teams discussed many topics, including how AI could be employed as agents to detect abnormal behavior of nodes on the Nexus network, i.e. the creation of numerous signature chains for the purpose of making an attack.

Team Hire: Front-End Software Engineer

Demorio (Demo) Fluker joined the Nexus development team in July. He has always been fascinated with the inner workings and compositions of things. He started with PC building and quickly escalated to building applications and websites. With the decision to finally turn that fascination into a career, he attended Woz U, graduating in 2018 as a certified web developer. Demo aims to  bring his creativity, talent, and positive energy to Nexus as a front-end software engineer. In his spare time, Demo enjoys producing instrumentals and songs in his home studio.

Nexus Prime GPU Miner (v1.0) Released

One of the most fascinating things about the Nexus blockchain is that it incorporates three different channels to validate data: a proof-of-stake, a hashing proof-of-work, and a prime proof-of-work channel. For over a year, our community has tried to solve a dilemma with the prime channel: our previous miners were too inefficient to compete with a monopolizing force. Now, thanks to Jack McGowen (@Blackjack) and Nexus Lover’s (@nobody) guidance, we have taken a crucial step in decentralizing the prime channel.

Lastly, we are very much looking forward to seeing you in Scottsdale next month at The Nexus Conference. This valuable exchange will provide many opportunities to expand our horizons and to personally interact to build the future together. See you there!

Thank you!
