Nexus is the first truly quantum-resistant blockchain, incorporating advanced cryptography designed to negate the threat posed by quantum technology of the future. The 3DC combines 571-bit private keys, 1024-bit Skein and Keccak quantum-resistant hashing algorithms, and an evolving signature scheme called signature chains. Signature chains update the private and public keys that secure your address and obscures them after each and every transaction, maintaining the integrity and security of your account even on mobile wallets. Signature chains offer several advantages over equivalent quantum-resistant schemes such as BLISS and Lamport signatures, being extremely compact and lightweight, making it ideal for blockchain applications. The Nexus coin (NXS) is the currency of the network. There’s no cap on the amount of NXS that will be minted. Instead, the coin has a 10-year distribution period in which 78 million NXS will be distributed until September 23rd, 2024. After this time, the supply will inflate each year by a maximum of 3% through the holding channel and 1% through the prime and hashing channels. Nodes create blocks, on average, every 50 seconds, and an NXS transaction requires 6 confirmations. Currently, most transactions cost 0.01 NXS. However, once the 3DC is built and 10-year distribution is complete, transaction fees will disappear. Instead, the system will absorb the fees through inflation. Nexus didn’t hold an ICO. Instead, the project has a Developer Fund that takes a small commission from mining rewards. This commission starts at 1.5% and increases to 2.5% over 10 years. Additionally, 20% of the block rewards are slotted for marketing as well as the production and launch of the Nexus satellite network. Colin Cantrell, also known as Videlicet, is the founder and lead developer of Nexus. He first named the project Coinshield (CSD) when starting in September 2014. The original code only contained the prime channel; the team added the hash channel in October 2014. In April 2015, the team rebranded to Nexus, and they added Proof-of-Holdings in July 2015. Besides partnering with Vector on the satellite network, Nexus has also joined forces with SingularityNET to provide their 3DC architecture to the project’s decentralized AI network. Moving forward, Nexus is releasing major updates following their TAO (Tritium, Amine, Obsidian) roadmap strategy. The releases include the 3DC, mobile wallets, quantum resistance, and the satellite network, among many other things. The creation of new NXS is capped at 3 percent per year and is earned through securing the network by mining or staking. The platform is developed and maintained by the Nexus Embassy who is funded through a 1.5% commission on each block produced and from funds acquired through early mining of NXS. The commission will also gradually increase from 1.5 – 2% over the next 10 years.
OriginTrail provides a helpful protocol solution to the problem of maintaining trust among all players involved in bringing a product to market by making the “chain” in “supply chain” more literal. Using blockchain technology, OriginTrail can append immutable data to products as they take each step along the supply route. Thus, each participant not only verifies that their conditions are being met but that at every previous stage, the right conditions were also met by everyone else. This is achieved by making an application layer that allows data to be collected in the real world, and then stored on the blockchain. OriginTrail started out by testing their tracking with organic beef products in 2014, and they are still mostly involved in the tracking of food products in general. It wasn’t until 2016 that they introduced a blockchain into their system. In January 2018, they raised US$22.5 million in their ICO. Since their ICO they’ve successfully launched their testnet, implemented privacy features, and achieved compliance with the GS1 standards that are integral to their business model. Their roadmap is robust and full of details, citing certifications with international bodies, alliances with companies, and entering new markets. Their mainnet is scheduled for launch in Q3 2018, and thereafter they appear to be on track to having all their services fully operational by 2020. OriginTrail is not the first or only company to recognize that supply chains could benefit a great deal from blockchain technology. Ambrosus is also going for the same market, though they seem to be focused on food and pharmaceuticals specifically. It should be noted that most supply chains have their own specific quirks, and so specialization might be be a good option. Another potential competitor of OriginTrail is Waltonchain, a company based in China that puts heavy emphasis on RFID chip scanning as part of their business model. In other words, where OriginTrail wants to leverage existing systems for their infrastructure, Waltonchain wants to try and establish new standards and methods. OriginTrail’s token is called TRAC, and it’s an ERC-20 token, making it storable on any ERC-20 compatible wallet. The total supply is capped at 500 million tokens. The value in TRACE tokens comes from their utility on the OriginTrail network. Tokens are spent to store, retrieve, and send data about supply chains. Since TRACE can be bought and sold in a speculative market, that creates the potential for the price to go up, which would be counter to the needs of people on the network looking for stable prices for setting and getting data. However, prices for data saving and retrieval will be determined by auction, which should counter increasing token value for those using OriginTrail as a service. The Internet of Things is a topic that gets a lot of press, and the general consensus is that it will be standard practice in the future for almost everything in the world to be tracked and traced for a wide variety of purposes. OriginTrail is one company that is demonstrating a concrete plan for exactly how that will be manifest. There really isn’t much to criticize in terms of the overall intention of the project. OriginTrail has identified a weak point in the very important world of supply chain management, that of reliable transfer of information all the way up and down the chain, and aims to provide a workable and clearly understood solution.
