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.
Ultra is a protocol and platform positioned to disrupt the $140bn USD gaming industry using blockchain technology to allow anyone to build and operate their own game distribution platform or virtual goods trading service. In doing so, it challenges the current monopoly held by industry heavyweights Steam, Google, and Apple. This will unlock new opportunities and create value for all the actors involved. Large commercial partnerships are signed, the protocol and platform have been built and will be launched in open beta in October 2019. UOS is the Token that powers the Ultra Ecosystem and can be used to purchase everything on the platform, including games, virtual items and ads for game developers. Ultra will accept traditional forms of payment such as Paypal and credit cards as well. These fiat currency transactions are converted to UOS seamlessly on the backend and are completed on the blockchain with UOS tokens. The token will also be used across the platform in many non-transactional ways including betting, tournaments, and donations. TIMELOCK: 10 to 20% of every transaction will be kept in a smart contract for 60 days. In addition, 5% of Ultra profits will be reserved for 2 years to fund exclusive games that use its blockchain and NFTs capabilities. ENGAGEMENT: Tokens are earned by performing specific actions such as; helping developers to build better games; watching ads; beta testing; answering surveys, and more. STACKING: Players can get rewarded with free games, swag and exclusive content just by holding tokens. SPENDABILITY: Users can buy and sell games/items for UOS, and in hundreds of shops through partners.
