XNO Nano Rank #414

Nano (XNO) is a low-latency, feeless cryptocurrency built on a block-lattice data structure, a form of Directed Acyclic Graph (DAG) in which each account maintains its own blockchain. It operates as a Layer 1 payment-focused protocol designed specifically for fast, efficient everyday transactions rather than general-purpose smart contracts. Consensus is reached through an Open Representative Voting (ORV) system, a delegated approach similar to Proof of Stake in which account holders delegate their voting weight to representatives, but without staking rewards or token inflation. The original Nano (originally called RailBlocks) paper and beta were published in December 2014, placing it among the earliest DAG-based cryptocurrencies, alongside projects like IOTA and Byteball. By assigning each account its own chain, Nano avoids the throughput bottlenecks of a single global ledger and eliminates the need for mining or high-power hardware, making the network lightweight and energy-efficient. The result is a simple, decentralized protocol optimized for high-performance, zero-fee digital payments.
