Nano, a low-latency cryptocurrency built on an innovative block-lattice data structure offering unlimited scalability and no transaction fees. Nano by design is a simple protocol with the sole purpose of being a high-performance cryptocurrency. The Nano protocol can run on low-power hardware, allowing it to be a practical, decentralized cryptocurrency for everyday use. The original Nano (RailBlocks) paper and first beta implementation were published in December, 2014, making it one of the first Directed Acyclic Graph (DAG) based cryptocurrencies [6]. Soon after, other DAG cryptocurrencies began to develop, most notably DagCoin/Byteball and IOTA. These DAG-based cryptocurrencies broke the blockchain mold, improving system performance and security. Byteball achieves consensus by relying on a “main-chain” comprised of honest, reputable and user-trusted “witnesses”, while IOTA achieves consensus via the cumulative PoW of stacked transactions. Nano achieves consensus via a balance-weighted vote on conflicting transactions. This consensus system provides quicker, more deterministic transactions while still maintaining a strong, decentralized system. Nano continues this development and has positioned itself as one of the highest performing cryptocurrencies. Nano is a trustless, feeless, low-latency cryptocurrency that utilizes a novel blocklattice structure and delegated Proof of Stake voting. The network requires minimal resources, no high-power mining hardware, and can process high transaction throughput. All of this is achieved by having individual blockchains for each account, eliminating access issues and inefficiencies of a global data-structure. We identified possible attack vectors on the system and presented arguments on how Nano is resistant to these forms of attacks. Check out CoinBureau for the complete review of Nano.
Ulord is a peer-to-peer value transfer public blockchain. Through building its blockchain underlying architecture and digital resource distribution protocols, it enables third-party developers to explore their own applications over open-source agreements to form a complete ecology of blockchain technology and applications. Based on various rules and protocols created by Ulord, it loads various types of digital resource application scenarios including text, pictures, music, video and software, providing a direct docking platform for information creators and consumers. Ulord Foundation, registered in Singapore, is the main operator of the Ulord project. It is determined to use the blockchain technology to create a new digital resource interaction platform. Ulord Foundation will standardize and manage the technology development, application docking, promotion and other related work of the Ulord Project. Ulord team brings together a large number of high-level R & D personnel led by more than 10 PhDs, with comprehensive blockchain technology application development capabilities. More than 50 excellent programmers and algorithm engineers in the technology development team have backgrounds in areas such as blockchain, cryptography, Internet information security, big data, cloud computing, artificial intelligence, finance, and management. There are senior scientists in cryptography and blockchain, and specialized blockchain project investors. In addition, Ulord team also maintains close cooperation with research institutes such as Windsor University in Canada, National University of Defense Technology, Wuhan University, Beihang University, Chinese Academy of Sciences and South China University of Technology, etc.
