Two innovative technologies, LISP and Nexus, have come together to create a one-of-a-kind scalable blockchain that many believe is the next generation blockchain solution the industry has been waiting for. LISP (Locator/ID Separation Protocol) was created by Silicon Valley’s, Dino Farinacci, to revolutionize scaling the Internet. The Nexus Hybrid Blockchain is being developed by twenty-eight year old Founder, Colin Cantrell, to solve the challenges of first generation blockchain architecture. Together, these two pioneers are advancing blockchain technology on the network layer in a way that has never been done before.
Dino is a software engineer and the largest individual contributor to running code on the Internet. He was the first ever Cisco Fellow appointed in 1997 and currently holds over 40 Internet and networking related patents. For the last 30 years, Dino has been a member of the Internet Engineering Task Force (IETF), which develops standards for the Internet we use every day. When Dino left Cisco in 2012, he wanted to pursue and focus on next generation use-cases for this new LISP technology. LISP is currently being tested by tech giants such as Comcast, Bloomberg, NBC and Cisco.
In 2017, he met Nexus Founder, Colin Cantrell, who is a self taught coder creating the Nexus blockchain from the ground up. Dino recognized the blockchain community was neglecting the real value of the network layer and making the same mistakes that were made when designing the Internet. Nexus was open to experiment, trial and deploy a LISP overlay, while Dino was eager to apply his networking experience to blockchain. The collaboration between Dino and Nexus was a perfect fit. Two years later, what started out as a passion project for Dino, is now the next generation scalable blockchain set to release this summer. Nexus Director of Business Development, Brian Vena said, “What Dino and Colin have created not only advances blockchain technology, but it will heavily impact our daily lives when it comes to the future of IoT and 5G. It also finally provides businesses a cost effective way to integrate a scalable blockchain solution with their current systems through easy to use plug and play APIs and advanced contracts that can be written in any coding language.”
The original Internet architecture was not built to handle the growing number of devices being used around the world or their ability to roam. This same architecture has now run out of IPv4 addresses (the Internet equivalent of phones numbers) which are required for devices and services to connect to the Internet. In order to solve this problem, Dino built the LISP overlay architecture to support both IPv4 and IPv6 addresses which will help make the Internet scale. With LISP, separating identity and location changes how you use the Internet. It allows you to roam, use multiple connections at one time and scale the core of the Internet. Scaling the core of the Internet is crucial so it can grow and support more devices and newer applications that are coming. “Today, people want performance, scale and accountability, and that’s exactly what LISP and the Nexus Hybrid Blockchain create together,” said Dino.
Nexus is the only blockchain using LISP, allowing it to scale along with the future advancements of the Internet and the new devices that connect to the network. The addition of LISP gives Nexus a scaling advantage by selecting the shortest paths between locations of Nexus nodes, allowing them to be located anywhere on the Internet, along with residential environments, cloud providers and mobile carriers. Using LISP also allows Nexus connections to remain active while the node moves around or temporarily goes off the network so re-connection and application state synchronization can be avoided. This increases the speed and performance of a Nexus node that no other blockchain in the world has.
The integration of Nexus and the LISP overlay also helps achieve scalability through reduced network latency in a truly unique manner. Just like the Internet, the 32-bit IPv4 address used by most network protocols will be unable to support the future growth of networked devices. Nexus and the LISP overlay will use 128-bit IPv6 EID addresses that can accommodate far more devices on the network. When asked about the future of LISP and Nexus, Dino believes the partnership will take advantage of more LISP features such as multi-homing, mobility, better security through the LISP mapping system’s access control features, crypto-EIDs for anti-spoofing and multicast miner pools. Dino says, “What the LISP layer provides you is an up to date network database and the Nexus Blockchain provides you with an immutable tracking database, the two can be used to provide robust and comprehensive data analytics. This is a data lake of information for machine learning models at multiple layers in the software stack that we have never seen before.”
Nexus has spent the last two years meeting with key executive decision makers and gathering market research in the areas of fraud, supply chain, digital rights and identity. This information has led Nexus to adapt their technical architecture and build a hybrid blockchain solution that allows businesses to utilize the benefits of both a public and private blockchain. The Nexus architecture solves the challenges of scalability and integration for a vastly improved user experience. APIs allow advanced contracts to be written in any language, ensuring easy integration, reduced development costs and a more efficient developer experience. With the Nexus mainnet set to release this summer, businesses looking for alternatives to first generation blockchains will now have a viable solution through the combination of Nexus and LISP.

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.
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.
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.
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.
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:
Long-time community members @Mirrax and @Lib, kindly showed the Nexus team some of the lands of Norway and held an interview with Colin in which he answered questions from the community. The interviews can be viewed on the following links:
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.
January 8th: Colin will speak at CES Las Vegas, on the topic of: “How blockchain is remaking the Media/Entertainment Business”
We would like to thank the following individuals from the community for their warm welcome in Norway, @Mirrax, @Lib and @Tjustt, and the many people who helped with the Warsaw Workshop, including @Kat @Zygmunt @Pawel @Kkbiznesowy and @Jakub.
The next Newsletter will follow January’s Tritium release. We would like to wish you all a lovely Christmas and New Year with your friends and family.
The new Nexus Tritium Wallet GUI (Graphical User Interface), which will replace the original Nexus QT wallet, debuts today in a public beta through October 27th, 2018. This new GUI is still in beta testing and should not be used as your primary wallet. The GUI is the second phase of the full Tritium release, following the Tritium Trust system integrated into the 2.5.1 wallet in September. This is the long awaited combination of new technology that Nexus has been developing throughout the year. Since the original vision, Tritium has expanded past these two phases to include the entire Tritium Software Stack which is in continuous development. Future releases will include Tritium Core with Signature Chains, Tritium Advanced Contracts and more.
Created by the Nexus developers Dillon Dugan, Kendal Cormany, Bryan Hallmark, Brian Smith, and Demorio Fluker, one of the most revolutionary changes for this wallet is the decoupling of the interface from the daemon (the back-end functionality tied to the Nexus blockchain). This significant advancement allows for modular design, separate updates, and enhanced ease of use for both developers and end-users.
The Overview page now contains a globe which shows your peer connections. Each wallet that your wallet connects to shows the city on the map along with the connection path. The globe can also be turned on and off based on user preference. Here you can easily view all of your important wallet statistics:
Currency value in USD
Number of transactions
Market price in BTC
NXS market capitalization
24 hour percent change
Number of connections
Staking information (block weight, trust weight, stake weight, interest rate)
The wallet also includes a send/receive module, transactions page, an address book, customization settings, market data, the trust list, and an integration with the Shapeshift Exchange, allowing you to exchange other cryptocurrencies and tokens.
The Console is a special module for developers that was a feature in the original QT. This is where you can use console commands such as:
