Nano is a groundbreaking digital currency that leverages a unique block-lattice data structure to provide an innovative, feeless, and low-latency transaction experience. Designed to be a practical cryptocurrency for everyday use, Nano enables instant transactions without compromising user value, allowing 100% of the transferred amount to reach its destination. Its eco-friendly approach circumvents traditional mining processes, making it a sustainable solution in the evolving landscape of cryptocurrencies. Utilizing an efficient Open Representative Voting (ORV) consensus algorithm, Nano maintains decentralization while processing high transaction throughput with minimal resources. This mechanism not only enhances security but also ensures quicker and more reliable transactions compared to conventional blockchains. The individual blockchains for each account eliminate access issues inherent in global data structures, contributing to Nano's resilience against potential attack vectors. Since its inception in December 2014, when it was originally known as RailBlocks, Nano has positioned itself as a leading cryptocurrency among Directed Acyclic Graph (DAG)-based projects, setting a high-performance standard that has influenced other cryptocurrencies like IOTA and Byteball. With its seamless application in local and international payments, Nano is particularly advantageous for remittances and microtransactions, simplifying the process of moving money across borders. Users interested in a decentralized financial future may find value in exploring the expanding ecosystem of applications, merchants, and exchanges that support Nano.
