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.
DERO is a new, experimental blockchain technology written in Golang with a focus on enhanced Privacy and Smart Contracts while maintaining the transparency and security of the blockchain. The goal is to create a unique state of the art blockchain technology with enhanced Reliability, Privacy, Security, Usability, and Portability by bringing together some of the best proven technologies like CryptoNote Protocol and Smart Contracts, thereby allowing for the creation of Private Smart Contracts. The Dero Project has written a unique new blockchain technology that is based on the CryptoNote protocol. Dero's goal is to create a unique state of the art blockchain technology with enhanced reliability, privacy, security, usability, and portability by bringing together some of the best proven technologies like the CryptoNote protocol and smart contracts, thereby allowing for the creation of truly private smart contracts. The Dero development team has implemented complete SSL across the Dero network which is a first on any blockchain. This encrypts the entirety of our network traffic, which greatly reduces our attack surface, while simultaneously preventing ISPs or other users from analyzing Dero’s network traffic.
