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.
The Swipe Wallet has been designed to require Swipe Tokens SXP to perform all functions and utility of the Wallet including to use the services and to make withdraws. Users on the Swipe Wallet can buy, sell, and pay with their cryptocurrencies to fiat directly within the Wallet application as well as purchase Gift Cards and make instant exchanges between all supported assets. Users are able to use their SXP tokens on launch and there are also tiered benefits based on the SXP holding on the Wallet Contract. All Swipe Wallets require a 1 SXP deposit to activate and utilize on-chain functions based on an audited Smart Wallet-Contract to perform its duties. The protocol has been designed and built on Ethereum and destroys 80% of network and transaction fees are and 20% of the fees are retained by the company.
